This study reports the first record of the rare terrestrial leech Chtonobdella catenifera (Moore, 1938) in the Barisan Nature Reserve, Sumatra, Indonesia, where 12 specimens were found attached to their vertebrate host: the Spiny Hill Terrapin Heosemys spinosa (Gray, 1831) and the Sundaic Giant Tortoise Manouria emys Schlegel & Müller, 1840 belonging to the families Geoemydidae and Testudinid…

Understanding intraspecific variation in nematodes is essential for accurate taxonomy and ecological interpretation. This study examined morphological and molecular variation in Tylencholaimus mirabilis from geographically distinct populations in South Africa and India using an integrative taxonomic approach. South African populations from Limpopo Province were studied using light microscopy (LM)…

Two new species of bogidiellid amphipods, Bogidiella isajii and B. painushima are described from an anchialine undersea cave in Minamidaito Island and freshwater flowing through a cave in Ishigaki Island, Ryukyu Islands. Bogidiella isajii sp. nov. differs from its congeners in the absence of an inner ramus on the pleopods, armature of uropods 1 and 2 rami, and shape of the telson. Bogidiella pain…

Three new dung beetle species (Onthophagus basilensis Génier sp. nov., O. castus Génier sp. nov., O. larseni Génier sp. nov.) are described from Bioko Island, Equatorial Guinea, and assigned to d’Orbigny’s group IX. Specimens were collected in montane and lowland rainforest using dung-baited pitfall traps. Diagnostic characters, including male genitalia and intraspecific variation, are provided. …

A new species, Neallogaster vietnamica, is described based on a male collected from Hoang Lien National Park, Lai Chau Province, Vietnam. It can be distinguished from the other species of the genus by characteristics of body maculation and the shape of the cerci. This is the first record of the genus from Vietnam.

Sulu Island is part of the Sulu Archipelago located between northeast Borneo (i.e., Sabah) and southwest of Mindanao Island. As such, Sulu Island can be an interesting location to study the biodiversity between the two aforementioned biodiverse and endemic-rich regions. For orthopterans, little is known about the species from Sulu Island. Based on recent sampling of the crickets and katydids on t…

Using molecular and morphological evidence, the axiidean family Strahlaxiidae Poore, 1994 is rediagnosed and confined to just Strahlaxius Sakai & de Saint Laurent, 1989. It includes three species S. plectrorhynchus (Strahl, 1862), S. waroona (Poore & Griffin, 1979) and the new species, Strahlaxius australiensis sp. nov. The distributions of the three species are discussed. Neaxius Borrada…

The genus Allopodagrion Förster, 1910 includes Neotropical damselflies distributed from southeastern Brazil to northern Argentina, with only A. brachyurum De Marmels, 2001 previously known in the larval stage. Here, we describe the larva of A. contortum (Hagen in Selys, 1862) based on specimens collected in Pico do Itambé State Park (Minas Gerais, Brazil). The relationship between the larva and t…

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…
