Leucocelis (Amauroleucocelis) vingerhoedti Perissinotto & Léonard, 2024, sp. nov.

Leucocelis (Amauroleucocelis) vingerhoedti sp. nov. (Figs 1, 3, 4) Diagnosis. The new species is most closely related to L. (A.) jeanneli, which was originally described as the only member of the then genus Amauroleucocelis (Bourgoin 1913). With it, L. (A.) vingerhoedti shares part of the chromatic dorsal ornamentation, being also mainly dark green with some testaceous-yellowish areas on the apical region of the elytral disc and on elytral and pronotal lateral margins as well as on clypeal surface (Figs 1 and 2). It differs from L. (A.) jeanneli by lacking the oblique stripes on the elytral disc and the longitudinal central band on the pronotum and scutellum. These are replaced by rust brown areas, in the shape of an inverted face on the pronotum, discal and marginal bands on elytra and variable triangular area on scutellum (Fig. 1 A). It also exhibits markedly raised elytral costae by comparison with L. (A.) jeanneli and most other species of the genus. The leg joints are dark brown to black in the new species, while they are reddish brown in L. (A.) jeanneli and undifferentiated from the rest of the leg surface (Figs 1 A, 2 A). The mesometasternal process is wider and mostly dark coppery-purple in L. (A.) vingerhoedti, but detectably narrower and metallic green to light coppery in L. (A.) jeanneli. In particular, the mesosternal lobe is slightly less produced forward in the former species than in the latter and exhibits a light brown colour, rather than metallic green like in L. (A.) jeanneli (Figs 2 A, 2 B). Finally, the aedeagal parameres of the two species are substantially different in the size of both their apical and basal extensions, with those of the new species being broader but shorter than those of L. (A.) jeanneli (Fig. 1 F, G). Also, within the apical part, the inner lobes of L. (A.) vingerhoedti are wider and the external ones protrude further forward than in L. (A.) jeanneli.
