Eugasteroides loricatus

Eugasteroides loricatus (Gerstaecker, 1869) Material examined: 2 males [CH7352 (SR, SF), CH 7353 (SF)], TANZANIA, Northern part, Lake Chala, Mt Kilimanjaro, Kilimanjaro Region, September 2010, leg. C. Hemp; 1 male (SR), TANZANIA, Longido, Arusha Region, Oktober 2010, leg. C. Hemp (all nominate subspecies). References: Grzeschik 1969, Hemp 2021 (all to nominate subspecies). Bioacoustics. Tegmina (Fig. 3) and the spectrum of the song (Fig. 6) do not show large differences to the typical Hetrodini pattern. However, the stridulatory file (Fig. 4C) shows a slight elevation in the middle, not seen in other Hetrodini species. The calling song consists of a long, uninterrupted trill (song type A) with a SRR of about 44 Hz (Fig. 10C; see Table 2). Genitalia. As in Eugaster, we could not find a titillator or other sclerotized genitalic elements despite careful examination. Chromosomes: 2n = 29 (28 + X0), FN = 29; pairs 1–14 and X chromosome acrocentric [2 males described earlier (Grzywacz et al. 2015: CH 7352, CH 7353)]; thin paracentromeric C-bands in all chromosomes.
