Spalacomimus spec. near verruciferus

S. near verruciferus differs only slightly morphologically from S. verruciferus distributed further north in Tanzania. In S. verruciferus the “warts“ on the 9th abdominal tergite are conspicuous structures while in S. near verruciferus these structures are low bumps or ridges rather than blade-like warts. Further, the posterior margin of the subgenital plate is differently shaped between these two species. Otherwise, in size and body shape, and the spination of the pronotum, both species are very similar.

Material examined: all TANZANIA, all Manyara Region: 1 male [CH7899 (SR, CHR)], Lossogonoi, Dezember 2014, leg. C. Hemp ; 1 male [ CH 7898 (SF; CHR)], Ruvu Masai Game controlled area. Lager 1, Dezember 2014, leg. C. Hemp.

Bioacoustics. According to the limited data, the species is bioacoustically quite similar to S. stettinensis and S. verruciferus . The echemes seem to be intermediate in length between S. stettinensis and S. verruciferus (29 syllables per echeme), but the SRR is with 14 Hz slower than in both ( Fig. 10I View FIGURE 10 ; see Table 2 View TABLE 2 ).

Genitalia. The genitalic sclerites ( Fig. 11F View FIGURE 11 ) are similar to that of S. verruciferus .

Chromosomes: 2n = 24 (22 + neo-XY), FN = 25; pairs 1–11 acrocentric, neo-X submetacentric and neo-Y acrocentric (2 males); thin C-positive paracentromeric bands in all autosomes, thick on the neo-X and neo-Y, as well as an interstitial one on the long pair ( Fig. 12K View FIGURE 12 ).
