germaini group

Included species: Loncovilius germaini ( Scheerpeltz, 1933) , L. hammondi sp. nov., and L. impunctus sp. nov.

Diagnosis: Head transverse, with coarse non-setiferous punctures; nuchal ridge complete dorsally, nuchal and infraorbital ridges joined; postmandibular ridge distinctly separated from eye margin and well-developed PMP ( Fig. 8E ; Brunke et al. 2019: fig. 1); right mandible with distal tooth bifid; left mandible only with proximal, non-bifid tooth. Pronotum transverse, outline evenly curved. Tergites III and IV with two patches of punctures of moderate size and density, with a middle impunctate line ( Fig. 9A ); ovipositor, its second gonocoxite without macroseta medially ( Fig. 9F ).
