Gromphas lemoinei Waterhouse, 1891: 60 [1st July 1891].
NAME-BEARING TYPE. — Holotype by monotypy (unknown sex), NHM.
TYPE LOCALITY. — Venezuela: La Guaira: La Guaira.
ETYMOLOGY. — The masculine singular genitive of the proper noun Lemoine, a French surname meaning ‘the monk’ (‘Le Moine’). Waterhouse (1891) did not explain after whom this eponym was formed, but I suspect it may have been the French entomologist Victor Lemoine (b.?-1897), the only Lemoine who I found associated with entomology in the late 19th century. Alas, apart from the fact that he was based in Paris and was a pioneer in the application of radiography in the study of arthropods (Lemoine 1897), almost nothing is known about Victor Lemoine (Anonymous 1897; Constantin 2012; Groll 2016).
DISTRIBUTION. — Open savannas, pastures and river sandbanks in the Colombian and Venezuelan Llanos and associated areas.
