Dong, Zhiwei, Yiu, Vor, Liu, Guichun, He, Jinwu, Zhao, Ruoping, Peng, Yanqiong & Li, Xueyan, 2021, Three new species of Lamprigera Motschulsky (Coleoptera, Lampyridae) from China, with notes on known species, Zootaxa 4950 (3), pp. 441-468 : 449-450

Diagnosis of Lamprigera male adults

Head totally concealed by pronotum dorsally ( Fig. 94 ); eyes kidney-shaped in lateral view and almost contiguous ventrally ( Fig. 95 ); vertex broadly impressed between eyes ( Fig. 95 ); antennae short, usually no longer than pronotum, 11–segmented, antennomeres 1–2 long and dilated, antennomeres 4–10 or 7–10 serrate, last antennomere briefly bifurcate apically. Pronotum ( Fig. 96 ) well-developed, semi-elliptical, with black central disc and varied translucent edge, as important diagnostic traits for species identification. Abdomen with seven visible sternites (visible sternite = ventrite); abdominal tergites strongly lobed. Luminous organs spot-like, each located in sublateral sides of last abdominal ventrite (i.e. ventrite VII). Male genitalia with medial lobe slender in dorsal/ventral aspect, moderately broad in lateral aspect; parameres subparallel sided, thick and evenly broad, as an important diagnostic character for species identification.
