First records of Croatian and Serbian Tetrigidae (Orthoptera: Caelifera) with description of a new subspecies of Tetrix transsylvanica (Bazyluk & Kis, 1960)

Abstract

A review of the Croatian and Serbian Tetrigidae is given and first records of Tetrix undulata (Sowerby, 1806) for Croatia and Serbia as well as Tetrix tuerki (Krauss, 1876) and Tetrix transsylvanica (Bazyluk & Kis, 1960) comb. nov. for Croatia are presented. The status of the genus Uvarovitettix Bazyluk & Kis, 1960 and the taxonomic position of T. transsylvanica comb. nov. are discussed. The genus Uvarovitettix Bazyluk & Kis, 1960 syn. nov. is synonymised with the genus Tetrix Latreille, 1802. A new subspecies from Croatia and Slovenia, Tetrix transsylvanica hypsocorypha Skejo, 2014 subspecies nova, is described. Tetrix pseudodepressa (Ingrisch, 2006) comb. nov. and Tetrix depressa (Brisout de Barneville, 1848) comb. nov. are moved to the genus Tetrix and the genus Depressotetrix Karaman, 1960 syn. nov. is synonymised with the genus Tetrix. Tetrix gibberosa (Wang & Zheng, 1993) inc. sed. and T. nodulosa (Fieber, 1853) inc. sed. are now considered to be species of uncertain placement within the genus Tetrix. New combination is also given to Paratettix tuberculata (Zheng & Jiang, 1997), primarily placed within the genus Mishtshenkotetrix: Tetrix tuberculata (Zheng & Jiang, 1997) comb. nov., but its placement within the genus Tetrix is also uncertain.

Two new species of the genus Formosatettix Tinkham, 1937 (Orthoptera, Tetrigidae) from Guizhou and Chongqing, PR China

“…Tinkham (1937) and Zheng (2005Zheng ( , 2009 described them as 'absent or degenerated', while Wei et al (2019) referred to 'tegmina' as absent, while hind wings as 'absent or very short'. Authors in other continents have similar issues, such as North America (Hancock 1902) or Europe (Skejo et al 2014), and have already proven that the flying organs of some Tetriginae species are degenerated, not absent. We have now also checked the flying organs of the Formosatettix specimens (ten species altogether).…”

“…Specimens of Formosatettix indeed have tegmina and hind wings present, but degenerated, very small, triangular and scaly or long-ovate, hind wind being distinctly longer than tegmenulum (Figs 1d, 5d). Formosatettix thus, has reduced tegmina and hind wings, not absent, just as members of the genus Nomotettix (Hancock 1902) in North America or Tetrix nodulosa and Tetrix transsylvanica in Europe (Skejo et al 2014).…”
