This study provides a comprehensive taxonomic revision of Autolytinae (Polychaeta, Syllidae) from Australian waters, based on extensive collections housed at the Australian Museum (Sydney). All known Australian members of the subfamily are described and illustrated and accompanied by diagnostic keys to genera and species. We report 26 species belonging to eight genera—one of them new to science: …

Nine species of Griburius Haldeman, 1849 and three species of Metallactus Suffrian, 1866, previously regarded as valid, together with two taxa previously treated as synonyms, are revised and critically discussed. According to the recent new diagnosis of Metallactus, all treated taxa are assigned to this genus. The following nomenclatural changes and synonymies are proposed: Metallactus corruscans…

Two new taxa of Platycleidini have been discovered in southern Albania, with one of them extending its range to the Greek border. In this paper, we analyse their morphological features, the characteristics of their acoustic signals, and phylogenetic relationships. These taxa clearly belong to the cluster of species comprising the four genera Montana, Amedegnatiana, Parnassiana, and Metrioptera s.…

A revised classification is presented for a group of Andean bees from Argentina, Bolivia, and Peru previously assigned to Liphanthus Reed (Andrenidae: Panurginae: Protandrenini) based on a phylogenetic analysis of 108 morphological characters. The results indicate that these species form a well-supported clade with the previously monotypic genus Incasarus Gonzalez, Rasmussen & Engel, renderin…

New records of some species of tiger beetles of the subgenus Leptinomera Rivalier, 1961 from Southeast Asia are presented and discussed. Cylindera (Leptinomera) catoptroides (W. Horn, 1892) is recorded for the first time from Thailand (Nakhon Si Thammarat and Yala Provinces), and Cylindera (Leptinomera) macrodonta Cassola et Probst, 1995 is recorded for the first time from Malaysia (Sabah Provinc…

This article provides a description of a new species of a catshark of the family Pentanchidae, Apristurus drona sp. nov. based on 4 specimens, which include two males and two females ranging from 439–473 mm TL, collected off the Kollam slope, Southwest coast of India, at a depth of 400–650 m. This new species is placed in the Apristurus brunneus subgroup among the three groups divided within the …

The species constitution and taxonomy of Zenithicola Spinola, 1841 is reviewed, resulting in description of Megaxestodes gen. nov.. for Megaxestodes crassus (Newman, 1840) comb. nov., Megaxestodes funestus (Chevrolat, 1874) comb. nov. and Megaxestodes socius (Chevrolat, 1874) stat. rev., comb. nov., the latter removed from synonymy with M. funestus. Zenithicola cribricollis Pic, 1941 syn. nov. is…

The present study deals with the morphological characteristics of the Indo-Australian geometrid moth genus Antimimistis Turner, 1922 sensu Holloway, 1997. The genus currently comprises four species. The moths are small, the upper side of the wings is usually dark brown, with irregular whitish lines, often with a pale central spot at the termen. Two species, A. circumsubteracta, sp. nov. and A. ma…

A new species of the extremely rarely collected genus Limnichopharus Miyatake, 1994, of the monotypic, ladybird beetle tribe Limnichopharini Miyatake, 1994 (subfamily Coccinellinae), Limnichopharus khaoyaiensis sp. nov., is described from Thailand, illustrated, and compared with the other congeneric species L. hainanensis Miyatake and L. borneensis Miyatake. This represents the third known specie…

The present contribution continues the revision of the subfamily Masarinae in Central Asia and deals with the genus Celonites Latreille, 1802. This genus includes 14 species: C. biinterruptus Kostylev, 1940, C. crenulatus Morawitz, 1888, C. foveolatus Kostylev, 1935, C. hystrix Kostylev, 1940, C. kozlovi Kostylev, 1935, C. kurzenkoi Mauss, Fateryga & Carpenter, 2026, C. maussi Fateryga, sp. n…

The Mexican leafhopper Gyponana germari (Stål), previously reported in Hawaii, Mexico, and Central America, has recently been documented in the continental United States from Florida. The species is here reported for the first time from Belize, El Salvador, and Honduras. Diagnosis of G. germari and its distinction from other similar Gyponana spp. in Florida are discussed. DNA sequence data for th…

The genus Erschoffia Swinhoe, 1900 is reinstated from synonymy with Aspitates Treitschke, 1825 to accomodate four ennomine species characterized by asymmetrical male genitalia. Erschoffia remmi, sp. nov. is described from the Western Tien Shan. E. acuminaria (Eversmann, 1851) exhibits a disjunct distribution between the highlands of Middle Asia and the Caucasus. The distribution and taxonomic sig…

Additional, abundant material of a recently described species of Mysida, Cubanomysis manuelortizi, previously known from a few individuals from the type locality in the SW Gulf of California and now collected in the SE Gulf of California, Mexico, is used to complete its description, particularly the morphology of thoracopods of both sexes. The new material matches the original description provide…

A survey of the ostracod fauna in the Chi River Basin in three provinces (Maha Sarakham, Kalasin and Roi Et) of northeast Thailand uncovered three new species of the tribe Cyprettadopsini of the Cypridopsinae: Cyprettadopsis hanjavanitae sp. nov., C. kalasinensis sp. nov. and Pseudocypretta sangpradubae sp. nov. Apart from its different soft part morphology, P. sangpradubae sp. nov. can be obviou…

We present a morphological description of a recently discovered species of spider in the family Trogloraptoridae from the Columbia River Gorge in northwestern Oregon. The family was previously monotypic (Trogloraptor marchingtoni) and only known from populations near the southwestern Oregon—northern California border. Trogloraptor tulishpun sp. nov. retains the key family synapomorphy, distinctiv…

The frog family Ranidae includes many cryptic taxa due to their high morphological similarity and broad distributions. The majority of original descriptions and distributional records have been based primarily on morphological identification alone, often lacking genetic support. This has led to instability and controversy in their taxonomy. The taxonomic status of Odorrana gigatympana (Orlov, Ana…

Two new species of Callyntrura Börner, 1906 are described and illustrated from the Indian Eastern Himalayan region (West Bengal, India). Callyntrura (Handschinphysa) tricolor sp. nov. closely resembles Callyntrura (Callyntrura) carli (Handschin, 1929) in general appearance but differs in the number of inner teeth on unguis, shape of basal chaeta of maxillary outer lobe, and chaetotaxy. Another ne…

A new species of the genus Calliteara Butler, C. hollowayi Qiao & Wang sp. nov., is described from Fujian and Guangdong provinces, China. C. rytovi Trofimova, Shovkoon et Witt, 2016 and C. brunnescens (Moore, 1879) are newly recorded in China. Illustrations of adults, wing venation and genitalia of these species are provided.

The genus Psilochorus Simon has long been suspected to be an exclusively North American genus, with only one exception: the synanthropic and widely distributed Psilochorus simoni (Berland, 1911). All Old World species and most South American species originally assigned to Psilochorus have been transferred to other genera in the last 25 years. Here we deal with the remaining South American species…

Two new species of pedunculate cirripede are described from lower Campanian basinal limestones of Höver and Misburg (Hannover area), northern Germany. These are the myolepadid Bosquetlepas schneideri sp. nov. and the large cretiscalpellid Jagtscalpellum kaeckei sp. nov. The occurrence of Bosquetlepas in basinal limestones is remarkable, as the genus was largely confined to shallow-marine and coas…
