West Indian Carabidae X. Three More Species From Jamaica, Including a New Cave Colpodes

International Journal of WEST INDIAN CARABIDAE X. THREE MORE SPECIES FROM JAMAICA, INCLUDING A NEW CAVE COLPODES* BY P. J. DARLINGTON 0 1 0 The following three species 1 Museum of Comparative Zoology, Harvard University Colpodes cavicola n. sp. Form of a slender d yonum (Platynus). but with long head and long, slender appendages; brownish piceous, margins of prothorax and elytra not paler, legs brownish piceous, antennae and palpi paler brown; moderately shining, elytra not much duller than head and prothorax; upper surface almost impunctate, with microsculpture lightly impressed, is.odiametric on front of head, transverse on prono.turn and elytra. Head rather elongate, .84 and .83 width prothorax (in o measured); eyes rather large, moderat'ely prominent; genae slightly shorter than eyes, oblique, not swollen; neck constrictio.n indistinct; front convex, with normal, parallel impressions anteriorly; posterior supraocular setae present, between posterio.r edges o.f eyes; anterior supraocular setae absent; antennae long and slender but otherwise normal; mentum with an acute tooth. Prothorax subquadrate; about as long as wide (but appearing longer), width/length 1.02 and 1.02 (in 0*9 measured) base about I/I0 wider than apex; apex slightly, broadly emarginate; base almost truncate; sides broadly, irregularly arcuate especially near middle of length, nearly straight and converging anteriorly, and nearly straight, converging, and usually slightly and broadly sinuate posteriorly; posterior angles narrowly rounded; lateral margins moderate, slightly wider posteriorly; both pairs lateral setigerous punctures lacking; disc no.rmal and normally imlbressed basal marginal line entire, apical one interrupted at middle. Elytra about 2 X wide as prothorax, long, almost subparallel; humeri prominent but broadly rounded, with basal margin entire and scarcely angulate at humeri; sides almost straight and slightly diverging to about middle of length, then arcuate to weak subapical sinuations; apices bluntly angulate or narrowly rounded about Psyche [December opposite ends of 2nd striae.; striae rather lightly impressed, vaguely punctulate; internals flat or slightly convex, 3rd normally 3-punctate. Inner wings ully developed; metepisterna long. Body below with fine punctures on sides o mesosternum, otherwise impunctate; abdo.men not pubescent. Tibiae not grooved on outer edges; hind tarsi slender, basal segments groo.ved above on outer side, less so on inner side; 4th hind-tarsal segment with very long outer lobe and much shorter inner one; 5th hind-tarsal segment without accessory setae. External sexual characters normal. Length 9.5-I I.o; width 3.2-3.7 mm. Holotype c (M. C. Z. Type No. 29,463) and 6 paratypes (2 in M. C. Z., 4 in Museum o, the Institute o Jamaica) all from St. Clair Cave, St. Catherine, Jamaica, 5 March 954, collected by C. B. Lewis and R. P. Bengry. This is a distinct, well defined species. It differs from all previously known Jamaican Colpodes in lacking both pairs o lateral prothoracic setae, and it has a unique combination o. ot’her specific characters. It is perhaps a distinct member o the Jamaican vayepunctatus-macersubovalis group, beginning to be specialized t:or lie in caves. However, the specialization has no,t yet gone ar. The brownish rather than black color and the long, slender appendages may be adaptations to life in caves; but the eyes are n.o.t much reduced and th.e wings are still (ully developed. Another, somewhat similar (but probably not related) agonine, more highly modified for life in caves, is Speokokosia corneti Alluaud of the CJrotte de Kokosi in the Congo in tropical Africa. In Speokokosia the eyes are much reduced, the wings have atrophied, and more depigmentation has occurred. In time, t’he Jamaican Colpodes may be expected to evolve in this direction. Callida caymanensis Darl. Entomologist’s Monthly Magazine, 83, 1947, 210. One specimen is before me from Crossroads, St. Andrew, Jamaica, 24 Nov. 954, T. H. Farr. This is the first Jamaican record for the species--but when I described it, rom the Cayman Islands, I suggested t;hat it might prove to be Jamaican. Pentayonica vittula Darl. Memorias de la Soeiedad Cubana de Historia Natural, 13, 1939, 100. Three specimens now before me constitute the first records of this species fro.m Jamaica. It was previously known only from Hispaniola. Two of the specimens are fro.m Upper Mr. View, St. Andrew, Jamaica, 9 Nov. 954, C. B. Lewis; and the other is from Beverly Hills, St. Andrew, 23 Dec. 954, R. P. Bengry.
