Dens dorsally with one proximal row of 3–4 blunt mac weakly ciliated and apically bullet-like, holotype with 3 ( Fig. 38C View FIGURE 38 ).

Etymology. Refers to the type locality of the new species, Botswana.

Remarks. Lepidocyrtinus botswanensis sp. nov. resembles L. annulicornis in antennae subequal to trunk length, Th II with 6 median mac in m1–2 complex and 11 posterior mac, Th III to Abd II with 9, 5 and 4 central mac, respectively, and unguiculus pe lamellae serrated. However, L. botswanensis differs from this species by color pattern (see remarks of L. africanus ), unguiculus pe lamella with a small proximal tooth (absent in L. annulicornis ) and manubrial plate with 1 mac abruptly acuminate at apex (2–3 in L. annulicornis ).
