Three new species are described and illustrated: O. intermedium sp. nov. (Nepal: Bagmati), O. conoideum sp. nov. (Taiwan: Nantou Hsien) and O. constrictum sp. nov. (China: Hubei). Three new synonymies are established: O. littorale Kraatz, 1857 = O. balassogloi Eppelsheim, 1888 syn. nov. = O. bucharicum Bernhauer, 1915 syn. nov.; Omalium rivulare (Paykull, 1789) = O. kabakovi Kashsheev, 1999 syn. nov. A lectotype is designated for Homalium balassogloi Eppelsheim, 1888. The habitus of the lectotype of O. balassogloi, and, in addition, the aedeagus of O. anguliferum Shavrin, 2025 and O. littorale are illustrated. Distributional maps for O. intermedium sp. nov., O. angustissimum Shavrin, 2023 and O. scapulare Coiffait, 1982 are given. Several species are recorded from a certain area for the first time: O. acutangulum Shavrin, 2023 from Koshi (Nepal), O. amicorum Shavrin, 2023 from Bagmati (Nepal), O. anguliferum from Hubei and Fujian (China), O. angustissimum from Bagmati and Koshi (Nepal) and O. flavotestaceum Shavrin, 2023 from Nepal.

A new genus of spider wasps (Hymenoptera, Pompilidae) from the Seasonal Semideciduous forests of southern Brazil

2025-09-17T11:01:42+12:00

A new genus and species of spider wasp (Pompilidae) are described based on male and female specimens collected in the Seasonal Semideciduous forests of Brazil. Nhanduara pytun Festa, Faria & Waichert, gen. et sp. nov. belongs to the tribe Ageniellini (Pepsinae), which is now recognized as comprising nine genera in the Neotropical Region. Relevant morphological structures are illustrated, and the taxonomic position of the genus is discussed.

Diversity of fleas (Siphonaptera) on small mammals within a subalpine ecosystem in the Nevado de Toluca Protected Area, State of Mexico

2025-09-17T11:02:34+12:00

In Mexico, few studies on the species of fleas associated with rodents in high mountain areas have been conducted, even though these mammals are mainly associated with these ectoparasites to a large extent, and it is a group of species that have a wide distribution and great diversity. The present study determined the diversity of ectoparasites (fleas) in rodents from a subalpine grassland within the Nevado de Toluca Flora and Fauna Protection Area, State of Mexico. Rodent sampling was carried out during the dry season (March and April) and rainy season (August and November) of 2017, at an elevation of 4,050 m above sea level. A total of 147 Sherman traps were set during three consecutive nights across both seasons. Fleas were collected from rodent hair and placed in 70% ethanol in separate vials for each specimen. A total of 217 rodents of three different species were captured: Reithrodontomys megalotis, Peromyscus melanotis, and Microtus mexicanus. From the last two species a total of 117 Siphonaptera from three families, five genera (Hystrichopsylla, Ctenophthalmus, Plusaetis, Strepsylla, Rhadinopsylla), and seven species were obtained. Plusaetis sibynus was the most abundant species and the one that showed the highest prevalence in P. melanotis, the most abundant rodent. Of the flea species found, Ctenophthalmus tecpin and Strepylla villai were new records for the State of Mexico, and three species of the genus Plusaetis had not previously been reported for the Nevado de Toluca area.

**New species and new records of Exetasis Walker (Diptera: Acroceridae) from protected areas of the Brazilian Atlantic Forest**

2025-09-17T11:03:23+12:00

Acrocerids are specialized spider-parasitoid flies rarely collected and scarcely represented in entomological collections. Thirty species of Acroceridae are known to occur in Brazil, five belonging to the genus Exetasis Walker. Herein is proposed a new species, Exetasis teresensis sp. nov., from the central corridor of the Atlantic Forest, in southeastern Brazil. Also, new records and a new data on morphological variation of Exetasis eickstedtae Schlinger are presented.

**New record of the genus Anaplectoidea Shelford, 1906 (Blattodea: Pseudophyllodromiidae: Anaplectoidinae) from India, with description of two new species**

2025-09-17T11:04:09+12:00

The genus Anaplectoidea Shelford, 1906 is an oriental taxon represented by 13 species in South, South East Asia and China. In the present study, we report the discovery of the genus Anaplectoidea in India, with the description of two new species, Anaplectoidea indica sp. nov. and Anaplectoidea garoensis sp. nov. from Jharkhand and Meghalaya, respectively. Based on a single female specimen, we also report one undescribed species of Anaplectoidea from the Western Ghats. The type specimens of the new species are deposited at the Southern Regional Centre, Zoological Survey of India (SRC, ZSI), Chennai.

**A new species of the eelpout genus Ophthalmolycus (Teleostei, Zoarcidae) from off South Orkney Islands, Weddell Sea**

2025-09-17T11:05:08+12:00

Ophthalmolycus lacrimegalos sp. nov. is described from a single specimen collected off the South Orkney Islands, Weddell Sea, Southern Ocean at a depth of 1,495 m. The new species differs from its congeners by the combination of extensive squamation covering the abdomen, predorsal area, and pectoral axil; an enlarged lachrymal bone, a wide bony interorbital space, and other characters (cephalic pore configuration, meristics, body proportions, coloration, etc.) in combination. This is the sixth species of the genus in the Antarctic waters, bringing the total number of known species in the genus to ten. However, the distinction of Ophthalmolycus in its current composition from the species-rich genus Lycenchelys requires elucidation. A revised key to the species of Ophthalmolycus is provided.
