The zoogeographical analysis of true bugs (Cimicomorpha, Heteroptera) of the Western Tien Shan

Abstract

This article presents a zoogeographic study of true bugs of the infraorder Cimicomorpha (Heteroptera) in the Western Tien Shan. Species were collected from several localities in the Western Tien Shan, ranging from lower elevations to high-altitude areas. The recorded species were assigned to 18 zoogeographical regions based on their distribution trends. A total of 89 species were identified and assigned to five families: Miridae, Tingidae, Nabidae, Anthocoridae and Reduviidae.

The results showed that the Holarctic zoogeographic region is represented by 15 species, including 12 species (80%) of the family Miridae, 2 species of Nabidae, and 1 species of Anthocoridae. The Trans-Palaearctic realm contains 15 species, primarily Miridae (10 species). The Trans-Eurasian and Western Eurasian zones display the greatest species richness, with 16 species (18%) and 17 species (19%), respectively, where in Miridae constitute 50-65% of the species in these locales. In other regional zones, such as the Holarctic-Oriental, Holarctic-Neotropical, Trans-Palaearctic-Oriental, Western Palaearctic, Eastern Palaearctic, Central Tethyan, Iran-Turan, Euxino-Iran-Turan, Turan-Turkestan-Altai-Gobi, Euxino-Kazakh-Altai-North Turan, Euro-Siberian-Kazakh, European-Kazakh, Central Asian-Kazakh and Turkestan Mountain areas, 1 to 3 species of true bugs were noted, with particular territories showing dominance by Nabidae, Tingidae and Reduviidae.

The gathered information supplements the understanding of the zoogeographic spread of Cimicomorpha in the mountain environments of the Western Tien Shan and can act as a foundation for future exploration of biodiversity and the safeguarding of native species.
