New Species of Southern Spiders

International Journal of NEW SPECIES OF SOUTHERN SPIDERS BY ELIZABETH B. BRYANT Museum of Comparative ZoSlogy Cambridge, Mass. BY ELIZABETH B. BRYANT 0 Cambridge 0 Mass. 0 0 Fig. 8, a, b, c, d, e During the winter and spring of 1935 a student at Southern Methodist University collected spiders throughout Dalla.s County, Texas. It i,s a section o.f the country from which little is known of the, spider fauna. Among them were five new species and the male of a. species known only from the type from Okefenokee Swamp, Georgia. From a small collection from Florida two species were found to be new and from the Florida. Keys was found a male. of a Cuban species known only from the female. Ma.ny species of spiders have been found to be, common to. Florida and Texas. - Female. Length, 2.5 mm. ceph., 0.7 mm. abd., 1.6 mm. width of ceph. 0.8 mm. Cephalothorax yellowish white with a dark margin, and media.n area from .eyes to, posterior margin shaded with dark gray, black a.bout eyes, broader than long, thoracic groove long and lightly impressed, clypeus protruding and shaded with gray; eyes closely grouped on a distinct elevation which falls away on all sides, anterior row procurved, a.m.e, largest of eight, round and dark, separated by more than a diameter and almost touching a.l.e, which are half the size, flat and white, posterior row about the same length, strongly procurved, p.l.e, little smaller than a.m.e., round and da.rk and almost touching a..m.e., p.m.e, flat., white and triangular, separated by their long diameter; quadrangle of median eyes slightly wider in front, and as high as wide; clypeus protruding and longer than quadrangle with a few colorless hairs at margin and a. pair of very long hairs projecting forward directly above a.m.e. mandibles colorless, weak and covered with long hairs, many with globular tips, fang impossible to. see; labium triangular, as high as wide at base.; maxillae pale. with many hairs, curved and almost surrounding labium, pedipalps colorless, long and parallel, extending 2orward with a single claw; sternum colorless, wider than. long, margins with many short hairs; abdomen oval, two. thirds as wide as long, base slightly bilobed, a dull tan thickly with irregular chalky white spots, entire abdomen sparsely covered with very long colorless hairs, venter paler with the same chalky white spots; legs colorless with no indication of dark rings, hairy with many bristles that can hardly be. called spines, I and II emora with a double row of heavy bristles, calamistrum double, extending over little more than the. basal half of IV metatarsus; spinnerets protruding, o. the usual type; epigynum with a bilobed chitinized margin thinly fring.ed with long colorless hairs above a slightly darkened area with transverse wrinkles; above the. chitinized margin are two widely separated darkened areas. Male. Length, 2.0 mm.; ceph., 0.8 mm.; abd., 1.3 mm.; width of the cephalothorax 1.0 mm. Cephalothorax, pale as in female but without the dark margin, eye elevation higher than in female so that clypeus is almost vertical; palpus long, femora parallel, patella and tibia about equal length, erminal joint brown and palpal organ dark brown, projecting from cymbium quite the length of the joint as figured. Holotype 3 Texas; Dallas, 17 March, 1935, (S. Jones). Allotype Texas; Dalla.s, 28 March, 1935, (S. Jones). Paratype 3 Texas; Dallas, 14 June, 1935, (S. Jones). Paratype 9 Texas; Dallas, 13 May, 1935, (S. Jones). This genus has been represented in the United States by Oecobius parietalis (Hentz) found in the southern states. Chamberlin and Ivie have made a revision of the American species of the family in Ann. Ent. Soc. Amer., 1935, 28, pp. 262-2?.72, pls: 1-4. They have described a new species Oecobius isolatus from immature females found at Carmen Island, Gulf of California and Sycamore Creek, Arizona. This species has heavily annulated legs and a carapace blackish. The relative position of the. eyes is not given. As so many small spiders are carried by commerce., it was thought that there was a possibility that this species might be Oecobius maculatus Simon, the species found about the Mediterranean. As there were no specimens of this species in the museum collection, drawings of the Texa.n species were sent to, the Paris Museum and M. Berland kindly compared them with th two. European species. It was found to. be different from either. AGELENIDAE Tegenaria simplex sp. nov. Fig. 9 Female. Length, ceph., 2.2 mm. abd., 3.1 mm. Cephalothorax light y.ellowish brown, cephalic portion high, o.utlined with a broad stripe of dusky gray which continues to. the posterior margin, la.teral margins with a na.rrow black line and fringed with long dark hairs directed forward, thoracic groove long; eyes cover little more than middle half of the head, anterior row slightly procurved, eyes equidistant, a.m.e, smallest of the eight, separated by less than a radius, posterior row little than anterior, eyes equidistant, p.m.e, largest of the eight., separated by a diameter, lateral eyes almost touching and subequal; quadrangle oi median eyes narrower in front and higher than wide; clypeus more than a diameter of a.m.e.; mandibles vertical, long, front surface flat with many black bristles, fang oblique, superior margin with scopula of long hairs, four distinct teeth, inferior margin with four teeth, fang long; labium as high as wide, tip rebordered, lateral margins almost parallel and excavate at basal fourth; maxillm twice as long as labium with sides" parallel; sternum with broad lateral dark stripes broken by two pairs o. light spots oppo,site I and II coxse,, as wide as long, sides almost parallel between I, II and IIi coxse, tip continued in a slender point between IV co.xm; abdomen two-thirds as wide as long, pale yellow with the usual grayish marks, tip much, venter pale with a gray rectangle from old to spinnerets, containing two pale poorly defined parallel stripes; spinnerets, superior pair with long basal joint, terminal joint about two-thirds as long, inferior pair shorter than basal joint of superior; legs long and slender, IV pair missing, pale, femora darker with faint gray rings; epigynum dark reddish-brown, with margins heavily chitinized, openings small and round, widely separated leading by spiral tubes to. sacs above. Holotype Texas; Dallas, near Southern Methodist University, 5 April, 1935. This species is marked like Tegenaria cavicola Banks, from Salt Petre Cave, Indiana. Unfortunately the type o.f this species is immature. The posterior row of eyes is not as strongly procurved as in Tegenaria domestica but the epigynum has the same broad lobe. It differs from Tegenaria obscura Banks, described from a single female by the different proportion in length of the joints of the spinnerets and position of eyes of posterior row. Schizocesa perplexa sp. nov. LYCOSIDAE Male. Length, 9.0 mm. ceph., 5.0 mm. abd., 4.0 mm. Cephalothorax with light stripe from second eye. row to posterior margin, with sides ev.enly co.nverging from the posterior eyes so that width at posterior margin less than half the. greatest width, covered with short white hairs, sides brown, thickly co.vered with short black hairs, no. indications of submarginal light stripe, very dark about eyes; eyes anterior row shorter than second row, a.m.e, separated by little over a radius, larger than a.l.e, and separated from them by less than a radius, eyes of second row separated by about a diameter; mandibles dark brown, covered with long black hairs, vertical, superior margin of fang groove with three teeth, middle, largest, inferior margin with three subequal teeth; labium higher than wide, lateral excavations at about one third the length; maxillm twice as high as labium; sternum and coxm light; abdomen with light brown basal stripe which disappears about middle:; in this the usual spear-mark can be traced outlined by black dots, sides black, entire abdomen thickly covered with long dark hairs and a few longer white hairs at base. on light stripe; venter dark with a few scattered lighter spots and a narrow, median light stripe, from fold to. spinnerets; legs, I left, II right missing, I leg darkest, o.thers same color as light stripe of cephalothorax, I tibia thickly covered with short erect black hairs, metatarsus with dark hairs not. as numerous, ?these black hairs not as long as diameter of joint and much shorter than in Schizocosa ocreatc (Hentz), spines, I tibia, dorsal 0, ventral, 2-2-2, basal and median pairs not overlapping, 1 lateral, metatarsus, 2-2, 1 lateral, posterior pairs spiny, III and IV ?tibim with dorsal basal and median spines; palpus, same color as legs, not as long as cephalothorax, seen from above, pa.tella little longer than tibia, tibia only slightly swollen, not as broad as long, a small dark do.rsal cusp extending towards cymbium, palpal organ lacking horn, principal tenaculum about the middle, unequally bidentate, lesser tenaculum situated above the middle, bent at right angles and turned downwards, above and parallel with the distal half is another slightly smaller process. , Holotype Texas; Dallas, Garland Swimming Pool, 25 March 1935 (S. Jones). This sp.ecies is a little larger than Schizocosa puebla Chamb. from Albuqu.erque, New Mexico, and is easily separated by the darker first leg, and tibia of the palpus shorter than patella and very diff.erent palpus.

Allotype 3 Texas; Kaufman, 3 miles E. ofParson?s Slough, 13 May 1935, (S. Jones). The holotype was described from a female, from Ok,efenokee Swamp, Georgia. Both male and female were taken at Pa.rson?s Slo.ugh, Texas. The. male differs from any species found in North America and Mexico by the processes on the patella, as all ?known species hav.e the processe.s on the tibia and patella smooth. Simo.n sta,tes that O. lepidus Blackw. (similars Stol.) ha,s a process on the. patella. D?RASSIDAE Nodocion agilis sp. nov. Male. Length, 5.0 mm. ceph., 2.5 mm. abd., 2.8 mm.

Holotype 3 Texas; Dallas, house on Oak Cliff, 15 May, 1935, (S. Jones). The. genus was based o.n a female from California. Chamberlin described one male that has a similar palpal organ but differs from the Texas species by the proportion of the joints of the palpus and he much longer tibial spur. Drassyllus pullus sp. nov. Male. Length, 5.1 mm. ceph., 2.2 mm. abd., 3.0 mm. Cephalo.thorax dark brown with no. light area, thoracic groove short but distinct, sides evenly rounded, front margin about same width as posterior; .eyes covering middle half of head, anterior row straight, a.m.e, smallest of eight, separated by less thaa a diameter and rom a.l.e, by less than a radius, a.1..e, largest of eight, posterio.r row a little longer than anterior row, straight, p.m.e, little smaller than a.l.e, round, separated by a diameter and fro.m p.l.e, by less; quadrangl.e of median eyes slightly narrower in front and higher than wide; clypeus less than diameter of a.m.e. mandibles dark brown, vertical, median margin covered with long, fang groove slightly oblique, superior margin with numerous stiff bristles and two subequal teeth, inferior margin with three small t.eeth, ang stout at base and evenly curved; labium higher than wide, lateral margin excavate at basal third then sides slightly inclined towards tip; maxillse once and a half times as high as labium; palpi inserted very near the tip; maxillse distinctly impr,essed; sternum brown, two-thirds as wide. as long, ending in a blunt point in front of IV coxm, sides with numerous long bristles; abdomen oval, a dark gray, thinly cover.ed with long hairs, basal scutum very distinct extending one. third length of abdomen, venter pale, with a scutum separate rom dorsal and extending from pedicle o old; inferior spinnerets separated by more than a diameter; legs, I pair, and II right missing, dark with many long hairs and bristles, spines, II tibia, 0 spines ventral or lateral, metatarsus, 2 basal, rather w.eak, IV tibia, 0 spines dorsal but a lateral pair; palpus not as long as cephalothorax, seen from abov.e patella longer than tibia, tibia longer than wide, tibial apophysis longer than joint and extends one half length of cymbium, slender and smo,oth, embolus, short, staring from near the tip, ma.king an abrupt turn soon after its origin, on, opposite side. of tip a slender black spine which extends slightly outside on cymbium, seen from the side between the embolus and the black spine, are. two leaf-like pieces with dark margins which cover the parts at the tip like a veil; a.t base of the organ is a dark round knob. Holotype 1 3 Florida;Coral Gables, 17 June, 1935 (0. C. Webb). Herpyllus faxoni sp. nov. F.emale. Length, exclusive oi spinnerets, 7.5 mm. ceph., 3.5 mm. abd., 4.0 mm. width o.f abd., 2.6 mm. Cephalothorax golden brown, covered with fine white hairs and long scattered black hairs, widest between second and third pair o. legs, much narrowed anteriorly, gently rounded, thoracic groove, distinct; eyes, anterior row slightly recurved, a.m.e, largest of the eight, separated by a radius and almost touching a.l.,e., posterior row procurved so that anterior_margin of p.m.,e, and middle of p.l.e, form a straight line, p.m.e, slightly angul.ate rather than oval, separated by a little more than their long dia.meter and by a little less from p.l.e., lateral eyes subequal and separated by less than a diameter; quadrangle of median eyes wider in front and slightly higher than wide.; clypeus about one-half diameter of a.m.e. mandibles vertical, cone. shaped, brown covered with long black hairs, ang groove shor, inferior margin with no teeth, superior margin with very small nodules, fang short; labium almost twice as high as wide, lateral margins at basal third slightly excavate; maxillm not twice as high as labium, only .slightly impressed, slightly inclined over labium, upper margins rounded; sternum oval, slightly narrowed between first coxm, lateral margins slightly emarginate, tip, obtusely pointed in front of ourth coxm; abdomen dark gray with a median light stripe, wide at base, sides converging and almost meeting at middle and continuing on posterior half as a much narrower spot that does not reach tip; venter light gray; legs, left III missing, 4-1-2-3, same color as cephalothorax, thinly covered with fine dark hairs, anterior metatarsi and tarsi with dense scopula, spines, I tibia, I-I-I, basal, median and apical, left tibia with basal spine misusing, metatarsus, 2 basal, II tibia, I-I, median and apical, spines more numerous on posterior pairs, III tibia, dorsal, I basal spine, IV tibia dorsal, 0 spine; epigynum, the. openings a. short distance above the fold, connected with fold by a h.eavily chitinized groove, above are the round receptacles separated by half a diameter. Holotype Florida Sebastian, F.ebruary, 1932, (G. Nelson). This species differs from others found in Florida. by the procurved row of posterior eyes, quadrangles of median eyes wider in front, and the lack of dorsal spine on the IV tibia. Herpyllus cratus Chamb., also from Florida, is immature and so. is difficult to place. It is much darker in color, possibly due to. the length of time it has been in alcohol, it is la.rger, the. spines on the anterior tibim are. not paired, the. epigynum while showing the chitinized grooves will be evidently much longer, but it has a dorsal spine at the base oi III tibia and none at the base of IV tibia. CLUBIONIDAE Clubiona transversa sp. nov. Female.. Length, 8.6 mm. ceph., 3.1 mm. abd., 5.5 mm. Cephalothorax pale yellow shading to brown near the eyes, sides almost parallel, front broad, thoracic groove distinct; eyes, anterior row straight, eyes subequal and equidistant, s.eparated by less than a diameter, posterior row longer than anterior, covering almost entire width of head, straight or very slightly procurved, eyes subequal p.m.e, slightly p.l.e, tha.n to each other; quadrangle of median eyes narrower in front and wider behind than high; clypeus less than a radius of a.m.e. mandibles very dark brown, swollen at base, long, boss .small, ang groove slightly oblique, superior margin with one large tooth, preceded by several small teeth and followed by one medium sized tooth, inferior margin with two teeth, ang, sto.ut and evenly curv,ed; labium twice as high a.s wide, lateral margins excavate on basal third, tip, slightly narrower than base; maxilla twice as high as labium, tips slightly dilate; palpus inserted at basal third; sternum twice as long as wide, width of labium in frontand pointed in front of IV coxm; abdomen oval, twice as long as wide, pointed above spinnerets, a dirty white, shading to a light brown at tip, venter pale with a iaint, dusky median line; legs, 4-1-2-3, right I and IV missing, pale dense scopula on anterior tarsi and metatarsi, faint scopula on distal half of anterior tibia, spines, I and II ?tibia, 2-2, long ventral, 0 lateral, metatarsi 2, basal, ventral, O lateral; epigynum wider than high, convex, with a dark narrow median septum which starts from a heavily chitinized ridg.e and curls under the fold midway in the clear area each side., starting from the median septum is a narrow dark transverse bar which does not reach outer margin, openings probably near the ends o.f the, chitinized ridge. Holotype 9 Texas; Dallas, White Rock Lake, 25 March, 1935. (S. Jones). Wulfila immaculata Banks Bull. Amer. Mus. Nat. Hist., 1914, 33, p. 640, pl. 43, fig. 7. Male. Length, 4.0 mm. ceph., 1.5 mm. abd., 2.2 mm. (measur.ement of length is without mandibles and spinnerets). Cephalothorax almost white, sparsely covered with colorless hairs, not very high, sides evenly rounded, thoracic groove a depression rather than a groove., at anterior outer corner is a darkened vertical cusp or spur similar? to figure of W. tropica Petrunkevitch Trans. Conn. Acad., 1930, 31, p. 68, figs. 56 to 60; eyes, very little black pigment about eyes, anterior row slightly recurved, a.m.e, smallest, of eight, separated by a scant diameter and from a.l.e, by more than a diameter, posterior row longer than anterior, procurved, eyes equidistant and subequal; quadrangle of median eyes narrower in front and as high as wide; clypeus one. and a half diamet.ers o a.m.e.; mandibles three-fifths as long as cephalothorax antenuate, outer margins parallel, iang groove long, oblique, superior margin with a distinct carina ro.m base., o.f fang ending in fiv.e teeth which extend on median margin, inferior margin illy defined and impossible to. see. any teeth; Petrunkevitch in redescribing the female. W. immacula,t.a states, Trans. Conn. Acad., 1930, 31, p. 85, that the mandible wh.en stained and mounted on a slide shows a row o.f nine. small teeth, very scant scopula on superior margin only, fang long and sinuous; labium higher than wide; maxillm twice as long as labium, tips slightly widened, palpi inserted at basal third; sternum flat, oval, IV coxm separated by a diameter; abdomen oval, more than twice, as long as wide, colorless, spinnerets extending beyond tip, openings o tracheal spira.l.e about middle; legs, I pair much the longest, fern., 3.0 mm. pat. rib., 4.6 mm.; metat., 4.1 ram.; tar., 2.0 mm.--13.7 mm. Spines colorless, emur, 3 dorsal serial, tibia, 2-2, ventral, 2 lateral, metatarsus, 2, basal, 2 lateral, spines more numerous on posterior legs;, longer than cephalothorax, tibia longer than patella, but little over half as long a terminal joint, tibial apophysis a small abrupt, cusp at right angles irom the joint with three short spines on ventral side and several long bristles on exterior. Allotype Florida; Bicknell?s Hammock, 30 April, 1935 (Gribbins). The, type, a emale rom Vinales, Cuba, is in the American Museum of Natural History. It has been ound since at Porto Rico and Mona. A emale was taken at Siboney, Cuba, without the first pairof legs. Petrunkevitch gives a detailed description of the type. female in Trans. Conn. Acad., 1930, p. 85, fig. 72. Ttie male agrees with t.he emale with the long first legs, the eyes, teeth on the mandibl,es and number o spines on the. legs. The spines are diffieult to see. It does not agree with the definition of the genus given by Petrunkevitch, 1930, p. 66, but probably December when both sexes of all species are known, the difference in the number of spines will be modified. The cusps on the outer corners of the cephalothorax are. ,evidently a secondary sexual character.
