Abstract—Thermothrips Pelikán, 1949 with the single species Thermothrips mohelensis Pelikán, 1949 is recorded from Central Yakutia for the first time for Siberia. Keywords: thrips, fauna, Thermothrips, Thermothrips mohelensis, Central Yakutia DOI: 10.1134/S0013873820040107
developed. Median setae (S1) on abdominal tergites II– VIII long, with approximate bases (Fig. 1, 5). Tergite VIII without comb—the row of microtrichia; without ctenidia. Segment X of female with dorsal slit. Male with glandular area on abdominal sternites III–VII (Fig. 1, 6).
At present, 57 species of 3 families, Aeolothripidae, Thripidae, and Phlaeothripidae, are known in the thrips fauna of Yakutia (Evdokarova and Velikan, 2011; Evdokarova and Doricova, 2013; Shmakov and Evdokarova, 2013; Evdokarova and Zvarikova, 2016; Evdokarova and Vierbergen, 2018). We found in Central Yakutia a monotypical genus of the family Thripidae, Thermothrips Pelikán, 1949, new to the fauna of Siberia. Earlier, Thermothrips mohelensis was recorded for the European part of Russia from Kursk Province (Schliephake, 1977). These genus and species rare in Russia are described below.
The genus includes only 1 species. Thermothrips mohelensis Pelikán, 1949 Thermothrips mohelensis Pelikán, 1949 : 37–41. Material. Russia. Central Yakutia, environs of Yakutsk, Botanical Garden of IBPC SB RAS (62°01ʹN, 129°36ʹE), steppe slope of southeastern exposition and xerophytic meadow, Galium verum, 19.VI.2017, 15.VI.2018 (Т.G.

Description. Body and legs dark brown; femora and tibiae paler distally; tarsi yellow. Head transverse: width 170–175, length 122–139. Antennae uniformly dark brown. Ocellar setae I and II leveled with anterior ocellus (Fig. 1, 1). First pair of postocular setae strong; 3 other pairs small (Fig. 1, 1). Pronotum: width across anterior margin 185–195, that across posterior margin 215–225; length 100–115. Length of posteromarginal setae of pronotum 33–39; that of posteroangular seta 19–23. Wings slightly infuscate basally. Seta S1 on metanotum situated nearly in middle of sclerite. Length of middle dorsal setae of tergite IX 39–43.
Genus THERMOTHRIPS Pelikán, 1949 Thermothrips Pelikán, 1949 : 37–41. Description. Head with 3 pairs of ocellar setae (Fig. 1, 1). Antennae 8-segmented. 3rd antennal segment with simple sensillum; 4th segment with paired sensillum (Fig. 1, 2). Tarsi 1-segmented.
