Amerikeroplatus n. gen.

Type species. Amerikeroplatus dimorphicus n. sp., here designated.

Diagnosis. The following combination of characters will distinguish the genus Amerikeroplatus from all other Keroplatidae . A medium-sized (6–8 mm) keroplatid with unmarked wings, one-segmented palpus, 14 unmodified moniliform antennal flagellomeres, 3 ocelli, tibial microsetae irregularly arranged, tibial spurs 1:2:2, laterotergite and mediotergite bare, distinct membranous area below scutellum absent, posterior prostigmatic setae present, anterior prostigmatic setae absent, Sc long and ending in C, crossvein r-m usually present (Figs. 4a–b), but when absent, either very short radiomedial fusion (R S +M) present (Fig. 4c), or bm-cu, base Rs, R 4+5, and stem of M all meeting at a central point forming a clean “X.” R 2+3 absent, basal cell not reduced, crossvein bm-cu oblique, stem of M long, CuP long and reaching wing edge.

Etymology. The generic name is derived from a combination of America, referring to the distribution, and Keroplatus Bosc , the genus from which the family name is derived. Gender is masculine.
