Cryptopygiella musaphila Robinson, 1975: 41.

Material examined.

Dominica: Holotype ♂, La Ronde River, 15 February 1964, H. Robinson (USNM). Montserrat: 1 ♀, Bottomless Ghaut, 5 August 2005, yellow pan trap, V.G. Martinson; 1 ♀, Big River, 450 m, 16°45.690'N, 62°11.174'W, 28 June 2017, J.B. Runyon; 1 ♂, small ghaut, on Heliconia , 16°45.844'N, 62°11.402'W, 28 June 2017, J.B. Runyon (MTEC, USNM).

Distribution.

Dominica, Montserrat.

Remarks.

This is the first report of the monotypic genus Cryptopygiella outside of Dominica. Specimens seem to be restricted to the deepest ghauts on Montserrat. The male antenna and genitalia were illustrated by Bickel (2009). The male postabdomen is unique in being completely enclosed within an opening at apex of the preabdomen (Fig. 6B ). Adults collected in 2017 were found on large Heliconia leaves, a similar habitat to where they were found on Dominica "running over the surface of banana leaves" ( Robinson 1975).
