Two new species of the genus Terrobittacus Tan & Hua, 2009 (Mecoptera, Bittacidae)

Abstract

Two new species of Terrobittacus Tan & Hua, 2009 are described and illustrated from Sichuan and Guangxi provinces of China, increasing the species number of Terrobittacus to eight. Terrobittacus emeishanicussp. nov. is differentiated from its congeners by wings with distinct markings and a female subgenital plate with a V-shaped carina. Terrobittacus laoshanicussp. nov. can be recognized by the black terga VI–IX. A key to species of Terrobittacus is updated. The species distribution and the relationship between adult morphology and mating behavior were briefly discussed.

Biodiversity and Spatiotemporal Variations of Mecoptera in Thailand: Influences of Elevation and Climatic Factors

“…This differed slightly from a previous report by Bicha in 2022 [ 3 ], which documented 22 species from three genera ( Bittacus , Neopanorpa and Panorpa ), thereby bringing the total mecopteran fauna in Thailand to 23 species. Terrobittacus is a small genus comprising eight species that are endemic to China and distributed only at high elevations (950–2500 m) with cool conditions and moist forests [ 45 , 46 , 47 ]. The current study found this genus during the rainy season at elevations of 567 m (four specimens) and 1231 m (one specimen).…”
