Syntypes.

Ed. Luja / Kondué / Congo-Belge // Donateur 858a / Ed, Luja, / Lux[em]b[our]g V.1911 // Trochalus / Ferranti Mos. n. sp. [handwritten by Moser] // 2332, 1♂; ditto, Donateur 858b / Ed, Luja, / Lux[em]b[our]g V.1911 // 2333, 1♀; ditto, Donateur 858c / Ed, Luja, / Lux[em]b[our]g V.1911 // 2334, 1♀; ditto, Donateur 858d / Ed, Luja, / Lux[em]b[our]g V.1911 // 2335, 1♀.

Remarks.

The species was described from an unknown number of specimens ("ich widme diese Art dem Konservator V. Ferrant in Luxemburg, welcher mir einige Exemplare gütigst überlief”) from both sexes measuring 6 mm in body length. Luja had collected these during his third mission in Kondué.

The type locality is “Kassai” and none of the specimens preserved in the collection of the MNHNL come from this locality. However, Kondué is located in the Kasai region and some specimens in the museum show old labels referring “Kondué / Kassai / Congo, Luja" (see e.g. the following species). Considering Moser’s imprecision in mentioning type data (see Lomaptera viridipes ), it is likely that “Kassai” included both types of label.
