ZHUO-HENG JIANG, ZHEN-BANG XU, YI-TING LIN, CHANG-QIU LIU, XIN WANG, SHAO-JI HU — Tue, 05 Aug 2025 00:00:00 +1200

New discoveries and notes of the family Sphingidae Latreille, 1802 from China are reported. The rare species, Rothinjoa leucomelas Rothschild & Jordan, 1915 is reported from south Yunnan, which is a new genus record for China. Griseosphinx marchandi Cadiou, 1996, Smerinthulus baonganae Brechlin, 2016, Smerinthulus mirabilis mirabilis (Rothschild, 1894), Rhodoprasina floralis (Butler, 1876) and Dahira obliquifascia obliquifascia (Hampson, 1910) are new recorded from China. The female of Dahira klaudiae Brechlin, Melichar & Haxaire, 2006 is reported and illustrated for the first time, together with the female genitalia. New data from China are given for Amplypterus mansoni mansoni (Clark, 1924), Dahira yunnanfuana montivaga (Kernbach, 1966), Dahira yunnanfuana indicus Melichar, 2021, Dahira melichari Haxaire, 2021, Acosmeryx formosana arunachalensis Haxaire & Melichar, 2023 and Daphnusa haxairei Melichar & Řezáč, 2014. Color photographs of adult moths (in the wild and of museum specimens) and habitats are provided, together with distribution maps and, for most taxa, monochrome photographs of the male genitalia.

Parahesione dudahamra sp. nov., an eye-catching symbiotic worm from the Red Sea, with complementary description and notes on Leocrates giardi Gravier, 1900 (Annelida: Phyllodocida: Hesionidae)

VITALY SYOMIN, ARTHUR ANKER, GLAFIRA KOLBASOVA, SUSANA CARVALHO — Tue, 05 Aug 2025 00:00:00 +1200

A new, brightly red-coloured, symbiotic hesionid worm, Parahesione dudahamra sp. nov., is described based on the holotype and single specimen collected in the shore waters of the King Abdullah University of Science and Technology, Thuwal, Red Sea coast of Saudi Arabia. The new species is characterized by simple lateral antennae without distinct ceratophores, longest dorsal cirri reaching chaetiger 12, and longest ventral cirri reaching only chaetiger 4. The holotype was extracted from a burrow of an unknown host in very shallow water, close to mangrove roots. The diversified burrowing fauna of the type locality, including the possible infaunal hosts of P. dudahamra sp. nov., is briefly discussed. In addition, a full description and ecological notes are provided for another hesionid worm, Leocrates giardi Gravier, 1900, of which several specimens were extracted from burrows at the type locality of P. dudahamra sp. nov.

Morphological and molecular characterization of Heterosaccus papillosus Boschma, 1933 (Rhizocephala: Sacculinidae) and its effects on the swimming crab Charybdis anisodon De Haan, 1850 (Decapoda: Portunidae) in Nha Trang Bay, Vietnam

Tue, 05 Aug 2025 00:00:00 +1200

Rhizocephala parasites, particularly Heterosaccus papillosus (Boschma), profoundly affect the morphology and physiology of their crustacean hosts, including the economically valuable swimming crab Charybdis anisodon (De Haan). This study provides a comprehensive analysis of H. papillosus in Vietnam, integrating detailed morphological description with molecular phylogenetic analysis using 18S rDNA and COI mtDNA. We confirm the parasite’s identity but uncover a substantial COI mtDNA divergence compared to GenBank sequences. This study documented an 11% infection rate, with host sex and size influencing prevalence. Notably, H. papillosus induced significant morphological modifications in C. anisodon, including abdominal segment expansion in males and pleopod degeneration in both sexes. These results emphasize the need for integrated taxonomic approaches and highlight the substantial impact of rhizocephalan parasitism on economically significant crab populations.

**A review of Ephydrella Tonnoir and Malloch from the New Zealand subregion (Diptera: Ephydridae) with description of a new species**

WAYNE N. MATHIS, TADEUSZ ZATWARNICKI — Tue, 05 Aug 2025 00:00:00 +1200

The species of Ephydrella from the New Zealand subregion are reviewed, including description of one new species, Ephydrella bicolor (type locality: Chatham Islands, Chatham Island, Wharekuri (field and beach; 43°42.6'S, 176°35.05'W) and designation of a lectotype for Ephydra macquariensis Womersley and for Mydaezealandia glauca (Salmon). The latter name, M. glauca, is synonymized with E. novaezealandiae (Tonnoir and Malloch). Considerable new distributional data are provided and are based primarily on recently identified specimens. To facilitate identification, the tribe Ephydrini is characterized, as are the genus Ephydrella and all species from the New Zealand subregion. A key to the New Zealand species is included, as are numerous photographs of structures of the male terminalia.

New records and calling songs of Landrevinae (Orthoptera, Grylloidea, Gryllidae) from Sabah

Tue, 05 Aug 2025 00:00:00 +1200

We studied new material of six species of Landrevinae (Orthoptera, Grylloidea, Gryllidae) collected from recent field trips in Sabah. New locality records are reported for five species. Duolandrevus (Eulandrevus) borneo Gorochov, 2016 in Maliau Basin, Duolandrevus (Duolandrevus) spinicauda Gorochov, 2016 in Maliau Basin, Endodrelanva peculiaris Gorochov, 2016 in Sinipung Hill, Repapa denticulata Gorochov, 2016 in Maliau Basin and Repapa trusmadi Gorochov, 2016 in Bukit Hampuan and Tenompok Forest Reserve. Previously-unknown calling songs of three species are also described: Duolandrevus (Duolandrevus) spinicauda, Repapa denticulata and Repapa trusmadi. The calling song of Repapa is known for the first time.

**Distribution and some biological features of Arctodiaptomus (Rhabdodiaptomus) bacillifer (Koelbel, 1885) (Copepoda, Calanoida) in Kazakhstan**

KRUPA E.G., KENZHEYEVA A. — Tue, 05 Aug 2025 00:00:00 +1200

Based on the males and females’ morphology and own long-term data, the freshwater diaptomid copepod Arctodiaptomus (Rhabdodiaptomus) bacillifer (Koelbel, 1885) presence was confirmed at three localities of Kazakhstan: the ultra-fresh mountain lakes Markakol (Eastern Kazakhstan) and Upper Kolsay, and a small lake located in the floodplain of the Aksu River (Southeastern Kazakhstan). A. (R.) bacillifer is known from various regions of the world not only as an inhabitant of ultra-fresh and fresh waters, with a total dissolved solids of 0.08–0.81 g/dm³, but also in salt waterbodies (up to 58.1 g/dm³). The reasons for the contradictory information on the distribution and biology of A. (R.) bacillifer in Kazakhstan and other regions are discussed. A comparative analysis of the key identifying features of its morphologically close congeners A. (R.) bacillifer, A. (R.) acutilobatus (Sars, 1903), and A. (R.) salinus (Daday, 1885), which are often mistakenly identified, is provided. The necessity of critical analysis of data on the wide distribution of A. (R.) bacillifer in mineralized waterbodies of different regions of the world is emphasized, since A. (R.) bacillifer, in addition to A. (R.) acutilobatus, A. (R.) salinus, is mixed with other species of the subgenus, in particular, with “alpinus” and “rectispinosus”. The absence of A. (R.) bacillifer in the optimal gradient of water mineralization is likely caused by competitive relationships with other species of calanoid crustaceans, most often with Acanthodiaptomus denticornis (Wierzejski, 1887) and Arctodiaptomus (Rhabdodiaptomus) spinosus (Daday, 1891).

**First record of the genus Krenopelopia (Diptera: Chironomidae) from China, with a description of Krenopelopia wangi sp. nov.**

ZHI-CHAO ZHANG, JUN-WEI CHEN, YAN ZHANG, XIAO-LONG LIN — Tue, 05 Aug 2025 00:00:00 +1200

The genus Krenopelopia Fittkau, 1962 is recorded from China for the first time. Krenopelopia wangi Zhang & Lin, sp. nov. is described and illustrated as adults. Species status is supported by COI DNA barcodes. A key to adult males of Krenopelopia worldwide is presented.

**First Record of the genus Lagynodes Förster, 1840 (Megaspilidae: Lagynodinae) from India, with the description of a new species and a molecular analysis**

AMIT KUMAR GHOSH, VIKAS KUMAR, TOBIAS SALDEN, KAOMUD TYAGI — Tue, 05 Aug 2025 00:00:00 +1200

The subfamily Lagynodinae and genus Lagynodes Förster, 1840 (Hymenoptera: Ceraphronoidea: Megaspilidae) are reported for the first time from India. Lagynodes mikoi sp. nov. is described and illustrated from West Bengal, India. The species concept is based on an integrative taxonomic approach combining morphological and molecular characters. Comparison of the COI barcode further allows clear species delimitation from other published COI sequences of Lagynodes species.
