The type specimens of bees (Hymenoptera, Apoidea) deposited in the Zoological Institute of the Russian Academy of Sciences, St. Petersburg. Contribution IX. Family Megachilidae, tribe Anthidiini, species described by F. Morawitz

KONSTANTIN S. IVLEV — 2025-11-24

The type specimens for names of bee taxa in the tribe Anthidiini, described by Ferdinand Morawitz and which are deposited in the Zoological Institute, Russian Academy of Sciences (St. Petersburg) are reviewed. Primary types of 35 taxa are illustrated and detailed information is provided. Lectotypes are here designated for the following seven nominal taxa: Anthidium affine Morawitz, 1874, A. christophi Morawitz, 1884, A. insulare Morawitz, 1873, A. montanum Morawitz, 1865, Stelis aculeata Morawitz, 1880, S. scutellaris Morawitz, 1894, and S. simillima Morawitz, 1875. The types of Anthidium laticeps Morawitz, 1874, A. puncticolle Morawitz, 1888, and A. terminale Morawitz, 1893 have not been found and are probably lost.

**First report of the genus Swammerdamella Enderlein, 1912 (Diptera: Scatopsidae) in China, with descriptions of nine new species**

YISHEN XIAO — 2025-11-24

The genus Swammerdamella Enderlein, 1912 is first reported in China with nine new species described in this paper: S. flexuosa sp. nov., S. globus sp. nov., S. gracilis sp. nov., S. latilobata sp. nov., S. papillata sp. nov., S. planus sp. nov., S. ramulosa sp. nov., S. tricuspis sp. nov., S. venusta sp. nov. A key to known Swammerdamella species in China is also provided.

**The butterfly genus Laothus (Lycaenidae), with the description of a new species and a morphology-based phylogenetic outline**

CARLOS PRIETO — 2025-11-24

The taxonomy of the genus Laothus Johnson, Kruse & Kroenlein, 1997 is revised. A new species, Laothus isakubi Prieto, sp. nov., endemic to the Sierra Nevada de Santa Marta, is described. Adults and genitalia of the new species are illustrated and compared with its closest relatives, Laothus viridicans (Felder & Felder, 1865) and Laothus cockaynei (Goodson, 1945). An updated checklist and two dichotomous keys for the identification of males and females are provided. A phylogenetic analysis based on 22 morphological characters coded for parsimony resulted in a single most parsimonious tree of 30 steps with a CI of 83 and RI of 88, in which Laothus is recovered as monophyletic.

**Morphological redescription and DNA barcoding of Diamesa longipes Goetghebuer, 1941 (Diptera: Chironomidae: Diamesinae) from the Swiss Alps**

BRIGITTE LODS-CROZET — 2025-11-24

Morphological redescription of Diamesa longipes Goetghebuer with using syntype from the Ötztal Alps (Tyrol) as well as the adult male and pupa from the Zermatt valley (canton Valais) downstream of the Gornera glacier (Swiss Alps) is provided, and DNA barcoding for specimens from Swiss Alps is studied. Based on the morphology and DNA barcoding using 658-bp fragments of the mitochondrial cytochrome oxidase subunit I, indicate that D. longipes is closely related to Diamesa zagrosica Makarchenko et Semenchenko from Iran. Mean K2P interspecific distances between D. longipes and D. zagrosica were 4.72% which based on four species’ delimitation approaches (BIN BOLD, ASAP, mPTP, GMYC), confirms that these are valid species. Comments on the geographical distribution and ecology of this rare species in the glacial streams of the Swiss Alps are also given.

Julus bengeli sp. nov., a new millipede from the Altais, Siberia, Russia, showing strong sexual dimorphism in the gnathochilarium (Diplopoda: Julida: Julidae)

PAVEL S. NEFEDIEV — 2025-11-24

Julus bengeli sp. nov. is described and illustrated from the Russian Altais, southwestern Siberia, Asian Russia. The new species shows a strong sexual dimorphism in the gnathochilarium in males, viz. a distinct projection located parabasally on the gnathochilarial stipes, apically carrying a circular bundle of 15–17 elongated papillae/trichomes. Julus bengeli sp. nov. seems to be especially close to J. ghilarovi Gulička, 1963, but differs from it by the presence of a conical apical outgrowth of the telopodite 1 of leg pair 1, and a large anterior coxal outgrowths of leg pair 2 thickened in the central part. The distributions of all Julus species of the Russian Altais are mapped, and a key to species of the genus in the study area is given.

**Breaking ground below: first troglobitic Circoniscus (Isopoda: Scleropactidae) from Southeastern Brazil**

JÚLIA BARBOSA GALO — 2025-11-24

A new troglobitic species of the genus Circoniscus is described from Brazil. Circoniscus boitata sp. nov. is the first troglobitic species of the genus reported from Southeastern Brazil and is found in two caves within the Cavernas do Peruaçu National Park, in Minas Gerais state. Additionally, we provide the first identification key for the troglobitic species of Circoniscus, along with electron micrographs and ecological notes on the species and the conservation status of its habitat.

A catalog of the Milichiidae of Chile (Diptera: Carnoidea)

CHRISTIAN R. GONZÁLEZ — 2025-11-24

An updated catalog of the Milichiidae of Chile is provided. We present all valid names and synonyms for the 12 species and four genera distributed in the country, including information about name, author, year of publication, page number, type species, type depository, type locality, and references. Milichiella Giglio-Tos is the most species-rich genus in Chile, with nine species. The geographical distribution of the different species was compiled from bibliographic data and revised collections.
