A pictorial key to differentiate the recently detected exotic Haemaphysalis longicornis Neumann, 1901 (Acari, Ixodidae) from native congeners in North America

Until recently, only two haemaphysaline species, Haemaphysalis chordeilis (Packard, 1869) and Haemaphysalis leporispalustris (Packard, 1869), were known to occur in the United States, and neither was considered to be of significant medical or veterinary importance. In 2017–2018 established populations of the Asian longhorned tick, Haemaphysalis longicornis Neumann, 1901, were...

Description of Callophylla macrocephala sp. n. from southern Tanzania

A male cetoniine specimen from the old Schürhoff collection currently deposited in the Ditsong National Museum of Natural History (Pretoria, South Africa), was recently submitted for identification and has been found to represent a yet undescribed species of the poorly-known genus Callophylla Moser, 1916. The species is named C. macrocephala sp. n., in recognition of its wider...

A revision of Lachnodius Maskell (Hemiptera, Coccomorpha, Eriococcidae)

Lachnodius Maskell is a genus of three named species that are part of an Australian radiation of felt scale insects that induce galls on Eucalyptus and Corymbia (Myrtaceae). A female’s gall usually consists of an open-top pit in swollen plant tissue. Depending on the species, galls can occur on a host’s leaves, buds, stems, or trunk. Here, we redescribe the named species: L...

Prionospio cristaventralis sp. n...

Enantiomorphs and taxonomy of three conchological species in flat-shelled snails Trichocathaica (Pulmonata, Camaenidae)

Biomodal (flat/globular or slender/tall) shell/body shapes are associated with dichotomous (simultaneous reciprocal or non-reciprocal) modes of copulation behaviour in the fully-shelled stylommatophoran snails. In flat-shelled groups that copulate simultaneously reciprocally, no study has found an example of enantiomorphism that persists within a population. However, the original...

Onychocamptus Daday, 1903 from Thailand, with descriptions of two new species and two new records (Crustacea, Copepoda, Harpacticoida, Laophontidae)

In this paper, two new species of Onychocamptus Daday, 1903 are described from Thailand: Onychocamptus satunensis sp. n. and Onychocamptus tratensis sp. n. The following features mainly distinguish O. satunensis sp. n. from known species: internal sausage-like and internal rounded structures on cephalothorax and one outer seta on the male P5 exopod that is as long as the...

The freshwater crabs of Macau, with the description of a new species of Nanhaipotamon Bott, 1968 and the redescription of Nanhaipotamon wupingense Cheng, Yang, Zhong & Li, 2003 (Crustacea, Decapoda, Potamidae)

One new species, Nanhaipotamon macau sp. n., is described. The large flap on the male first...

Evidence of cryptic species in the blenniid Cirripectes alboapicalis species complex, with zoogeographic implications for the South Pacific

Rapa Nui, commonly known as Easter Island (Chile), is one of the most isolated tropical islands of the Pacific Ocean. The island location of Rapa Nui makes it the easternmost point of the geographic ranges for many western Pacific fish species that are restricted to the subtropical islands south of 20°S latitude. The blenniid fish species Cirripectes alboapicalis has been thought...

Genetic signatures of polymorphic microsatellite loci in the Ambiguous silver pomfret, Pampus argenteus (Teleostei, Stromateidae)

Pampus argenteus is a broadly exploited pelagic fish species, commonly misidentified as Pampus echinogaster. Genetic variation and population structure in Pampus argenteus was studied based on seven microsatellite loci. The observed high average allele number, heterozygosity values, and polymorphism information content of P. argenteus suggested high genetic diversity. No...

A new species of the genus Deinodryinus Perkins (Hymenoptera, Dryinidae) from the USA

A new species of Deinodryinus Perkins, 1907, is described from the USA, Texas: D. bimaculatus sp. n. Morphologically the new species is similar to D. masneri (Olmi, 1984), but it is distinguished by the head lacking a frontal line and the forewing crossed by two dark transverse bands; in D. masneri the head shows a conspicuous frontal line and the forewing is hyaline and without...

The structure of the male terminalia and their musculature of species of tanyderid genera Araucoderus Alexander, 1929 from Chile and Nothoderus Alexander, 1927 from Tasmania are examined and compared with each other and with published data on the likely relatives. The overall pattern of male terminalia of both genera is similar to those of most Southern Hemisphere genera, with...

A new treefrog from Cordillera del Cóndor with comments on the biogeographic affinity between Cordillera del Cóndor and the Guianan Tepuis (Anura, Hylidae, Hyloscirtus)

The Hyloscirtus larinopygion group is a clade of 16 species of large hylids that inhabit cascading Andean streams. They have brown coloration that, in most species, contrasts with bright marks. Herein morphological and genetic evidence is used to describe a new species of the group from Cordillera del Cóndor, a sub-Andean mountain chain that has phytogeographic affinities with...

Phylogeography indicates incomplete genetic divergence among phenotypically differentiated montane forest populations of Atlapetes albinucha (Aves, Passerellidae)

The White-naped Brushfinch (Atlapetes albinucha) comprises up to eight allopatric subspecies mainly identified by the color of the underparts (gray vs. yellow belly). Yellow and gray bellied forms were long considered two different species (A. albinucha and A. gutturalis), but they are presently considered as one polytypic species. Previous studies in the genus Atlapetes have...

Two new species of Amphinemura (Plecoptera, Nemouridae) from the southern Qinling Mountains of China, based on male, female and larvae

Two new species of the genus Amphinemura, A. albicauda sp. n. and A. dingoidea sp. n. from the southern Qinling Mountains, Foping County of Shaanxi Province, western China, are described based on both sexes and the larval stage. The new species are compared with related taxa, and the A. sinensis species group is defined for an Oriental lineage of the genus. Amphinemura sinensis...

Comparative larval ultramorphology of some myrmecophilous Aleocharinae (Coleoptera, Staphylinidae), with a first description of the larvae of Amidobia talpa (Heer O, 1841) and Oxypoda haemorrhoa (Mannerheim C.G., 1830), associated with the Formica rufa species group

The paper describes the external structures of the late larval stages of two Palearctic myrmecophilous staphylinids: Amidobia talpa and Oxypoda haemorrhoa associated with the Formica rufa species group. This is the first-ever description of the larva of Amidobia, and the only complete, detailed account of the morphology of this developmental stage in the genus Oxypoda currently...

A taxonomic revision and molecular phylogeny of the eastern Palearctic species of the genera Schizomyia Kieffer and Asteralobia Kovalev (Diptera, Cecidomyiidae, Asphondyliini), with descriptions of five new species of Schizomyia from Japan

The genus Asteralobia (Diptera, Cecidomyiidae, Asphondyliini, Schizomyiina) was erected by Kovalev (1964) based on the presence of constrictions on the cylindrical male flagellomeres. In the present study, we examine the morphological features of Asteralobia and Schizomyia and found that the male flagellomeres are constricted also in Schizomyia galiorum, the type species of...

Gastrocopta armigerella (Reinhardt, 1877) and Gastrocopta theeli (Westerlund, 1877) in western Tien Shan, Kyrgyzstan, and their further occurrence in Asia (Mollusca, Gastropoda, Pupilloidea)

Gastrocopta armigerella (Reinhardt, 1877) has been described from Japan and is widespread in the Far East and China. Surprisingly, a few occurrences in central and western Asia have also become known. Forcart (1935) found G. armigerella in northern Iran. The authors found evidence of G. armigerella in western Tien Shan, Kyrgyzstan. The form from northern Tajikistan described by...
