Remarks. This species was described from Suriname and is known only from its holotype (not studied here). The male of A. spinifera has a costal bulla on each forewing, probably two small ventromesal processes on segment VII, a pair of long dorsolateral processes on segment IX, and inferior appendages short and not fused to each other ( Flint 1974), being allocated here in the A. plaumanni Group. However, the male genitalia in A. spinifera are very distinctive, and can be easily distinguished from those of other Acostatrichia species by segment VIII having an acute median process on the posterior margin in ventral view, by bifid inferior appendages, and by the divided subgenital plate.

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