**Morphological and mitogenomic characteristics of Chinese endemic species Blaps (Blaps) chinensis (Faldermann, 1835) (Coleoptera, Tenebrionidae, Blaptini)**

LAN-FANG LIU — 2025-12-17

Blaps (Blaps) chinensis (Faldermann, 1835) is an endemic species to north-central China. We provide the first description and illustration of the egg and pupal stages of this species, supplemented by additional larval and adult morphology. Updated keys to 24 larval and 11 pupal stages of Chinese Blaps species are presented. Additionally, we report the first complete mitochondrial genome sequence and analysis for B. (B) chinensis.

**Notes on the genus Onychargia Selys, 1865 (Odonata: Zygoptera: Platycnemididae) with description of O. hungeri sp. nov. from southern Vietnam**

MINH KHANG TRAN — 2025-12-17

This study updates the distribution and provides notes on the habitat of three species of the genus Onychargia Selys, 1865 in Vietnam, including the description of a new species, O. hungeri sp. nov. (holotype ♂, 10.52238° N, 107.47591° E, altitude 41 m, Binh Chau-Phuoc Buu Nature Reserve, Ho Chi Minh City, southern Vietnam), which is described based on male and female specimens. The new species can be easily distinguished from two other congeners by having smaller body size, U-shaped pruinosity on male’s synthorax and differences in the male’s appendages structures.

Cold-water coral associated Acanthonotozomellidae (Crustacea, Amphipoda) off Aotearoa New Zealand, with description of a new genus and species

ANNE-NINA LÖRZ — 2025-12-17

Aotearoa New Zealand has some of the most diverse and abundant deep-sea cold-water coral fauna found in the world. The coral-associated fauna off Stewart Island was investigated and revealed Amphipoda of the family Acanthonotozomellidae Coleman & J.L. Barnard, 1991a. This is the first time this family is recorded from the south Pacific. In situ observations by the ROV MARUM Squid revealed camouflage colour patterns of the amphipods on different primnoid corals. Integrative taxonomy methods were approached, Paracanthonotozomella steffi gen. et sp. nov. is described in detail, including photographs, illustrations, confocal laser scanning microscope images, COI and 16 S sequences. A key to the world genera of Acanthonotozomellidae is provided.

Desdimelita awatschensis a new species of Melitidae Bousfield, 1973 (Crustacea: Amphipoda: Hadziida) from southeastern Kamchatka (Avacha Bay Pacific Ocean)

VJACHESLAV S. LABAY — 2025-12-17

A new amphipod species, Desdimelita awatschensis sp. nov., from the eastern coast of Kamchatka Peninsula (Northwest Pacific, Avacha Bay) is described. The new species is assigned to the genus Desdimelita Jarrett & Bousfield, 1996 in most of the characters: pleon segments smooth above, in the structure of the mouthparts, gnathopod 1 little sexually dimorphic, carpus of gnathopod 1 (male) long, deeper than wide, dactylus of gnathopod 2 (male) without outer marginal setae, bases of pereopods 5–7 large, regular, outer ramus of uropod 3 2-segmented, terminal article small, telson lobes normal, slightly fused basally. The new species have the bifid anterior lobe of the coxa 6 of females as in Desdimelita transmelita Jarrett & Bousfield, 1996, differs from last by the dorsal carination of urosome segment 1 with 3 subequal teeth. It also differs from D. californica (Alderman, 1936) by the structure of gnathopod 1 of male (the shorter, length 1.5 times as width) and by the structure of pereopods 5–7 (carpus short, 2/3 times as long as merus). Keys to the world species of the genus Desdimelita is provided.

**The ground beetle genus Zuphium and subgenus Chlaenius (Trichochlaenius) (Coleoptera: Carabidae) from Iran, with the description of two new species**

FARHAD ESHRAGHI MOFRAD — 2025-12-17

Two new species of ground beetle from Iran are described and illustrated. Zuphium seiedyae sp. nov., collected from the Zagros Mountains in the Fars Province, and Chlaenius (Trichochlaenius) shimbarensis sp. nov., found in Khuzestan Province, are presented with detailed morphological descriptions and illustrations. In addition, identification keys and images of all Iranian species are provided. The country record for Chlaenius (T.) gotschii Chaudoir, 1846 is corrected from Iran in Azerbaijan, Chlaenius (T.) albissoni Reitter, 1908 is recorded for the first time from Jordan.

**A review of Dictyoptera Latreille, 1829 (Coleoptera: Lycidae: Erotinae) of mainland China, with description of a new species from Jiangxi**

S.V. KAZANTSEV — 2025-12-17

The erotine genus Dictyoptera Latreille, 1829 of mainland China is reviewed. A new species, D. wuyishanensis sp. nov., is described from Jiangxi, eastern China, raising the number of Dictyoptera species in the continental part of the country to four. Dictyoptera bicoloricornis Pic, 1933 is transferred to Helcophorus Fairmaire, 1891 as Helcophorus bicoloricornis (Pic, 1933), comb. nov. The habitus and aedeagus of the holotype of D. gansuensis Kazantsev, 2004 are illustrated with colour photographs for the first time. A key to the Dictyoptera species of continental China and a list of species of the genus are provided.

**A new species of the genus Rhipidandrus LeConte, 1862 from China, with description of the immature stages (Coleoptera: Tenebrionidae: Bolitophagini)**

HENG ZHANG — 2025-12-17

Rhipidandrus LeConte, 1862 is a small genus of mycophagous beetles. Previously, only one species, Rhipidandrus speculifrons (Gebien, 1922), was known to occur in China. Here, we report the discovery of a new species, Rhipidandrus longipunctatus Zhang sp. nov., from the Qinling Mountains, Shaanxi. This new species is distinguished from all congeners by the presence of longitudinal punctures on the pronotum. Detailed morphological descriptions of the adult, larva, pupa, and egg are provided. Additionally, a key to the two known Chinese species of Rhipidandrus is included.
