Acostatrichia digitata Thomson & Holzenthal 2012: 21 View Cited Treatment , figs. 1A–1F, male; type locality: Venezuela: Bolívar: E Tumeremo, W Bochinche, Río Botonamo, 07°25.462’N, 61°14.318’W, 150 m.; type depository: UMSP.

Remarks. This species is known only from its holotype collected in Venezuela. The original description and illustrations are quite detailed, and they are not duplicated here (see Thomson & Holzenthal 2012). Acostatrichia digitata shows the main features of the A. brevipenis Group: the long and somewhat capitate ventromesal process on segment VII; segment VIII with ventrolateral processes; and the inferior appendages fused to each other with an apicolateral projection. The species is easily distinguished from the others by the ventrolateral processes of segment VIII each bearing a digitate lobe ( Thomson & Holzenthal 2012) and in addition, the subgenital plate is divided into two arms, in ventral view.

Distribution. Venezuela ( Fig. 16 View FIGURE 16 ).
