Alexandr Anichtchenko — 2024-12-27

The species status of Brachinus (Brachinoaptinus) tashkenticus Kirschenhofer, 1986 is restored . A differential diagnosis with related species is proposed. The taxonomic status and the type locality of B. (Brachinoaptinus) aktashiensis Kirschenhofer, 1986 are discussed. Photographs of habitus are given for all the three taxa of this group and the endophallus structure is studied and illustrated for the first time for two of them.

Longhorn beetles (Coleoptera: Cerambycidae) of Ossa massif, Greece

Jan Tatur-Dytkowski — 2024-12-27

The paper presents and summarizes data on the distribution of longhorn beetles on Mount Ossa in Eastern Thessaly, Greece. Observations are the result of numerous expeditions carried out within years 1999-2024 with various intensity. The paper comprises data on 158 species which reflects 33% of Greek Cerambycidae fauna including subspecies. In-depth literature review was conducted and published data was herein included. Remarks on interesting and rare species are provided with detailed collecting data. Habitus of selected species is presented. 126 taxons are recorded for the massif of Ossa for the first time. The total number of recorded long-horned beetle species indicates the high degree of ecological and environmental preservation of Mount Ossa.

A new species of the genus Asiodonus Legalov, 2010 (Coleoptera, Curculionidae) from India.

Andrei A. Legalov — 2024-12-27

A new species, Asiodonus chaunriensis Legalov, sp. nov. from Uttarakhand (North India), is described and illustrated. The new species is similar to Asiodonus solidus (Petri, 1901) but differs in the prosternum with strong postocular lobes, relatively straight sides of the pronotum, and a mesosternal process that is not produced anteriorly. This is the southernmost find of the Asiodonus Legalov, 2010 and the first record of the genus in India.

A new species, Sphinxis yunnanicus Legalov, sp. nov. from Yunnan (China) is described and illustrated. The new species is closely related to Sphinxis uniformis Kojima et Morimoto, 2000, but differs in that the rostrum is longer than the pronotum, the elytra are narrower towards the apex, the mesosternal process is distinctly broader than the coxa, and the integument is thinly covered with greyish to dark setae. This is the first record of this genus from mainland China.

On the distribution of Metopides nivosus (White, 1858) (Coleoptera: Cerambycidae) in Pakistan .

Arvīds Barševskis — 2024-12-27

The paper provides new information about the distribution of Metopides nivosus (White, 1858) in Pakistan. The results of the study show that this species is more widely distributed in Pakistan than previously thought. New faunistic data presents material near the border of Afghanistan. It can be assumed that the distribution of the species is wider in Asia and it potentially can be found in Afghanistan.
