Ruta, Rafał, 2019, Calvariopsis gen. nov., a new genus of Neotropical Scirtidae (Coleoptera: Scirtoidea), Zootaxa 4604 (1), pp. 1-41 : 37

Calvariopsis sp., female, French Guiana

( Figs 2E , 4 D–E, 27J)

Material examined. 3 females ( MNHG): “ Guyane Francaise \ Mont Grand Matoury \ 2.– 11.10.1995 \ M. Kocian lgt.” .

Notes on morphology. Body very small (TL 1.90–1.95 mm), brownish black, elytra without modifications. Gonocoxites moderately wide, subtriangular, with subapical gonostyli ( Fig. 27J ). Bursal sclerite in form of elongated plate, poorly preserved in the specimens studied.

Remarks. These are females of either C. bituberculata sp. nov. or C. kawense sp. nov. As both species are sympatric and very similar externally, it is impossible to assign females to any of the two species. Undoubtedly a member of group II.
