Anacroneuria tempisquito sp. n.

( Figs. 11-15 View Figs )

Material examined. Holotype ♂, Costa Rica, Guanacaste Province, Estación Biológica Maritza, Rio Tempisquito , 21 May 1990, light trap ( USNM).

Adult habitus. Head yellow except for diffuse brown area forward of ocelli and dark brown lappets and antennae ( Fig. 11 View Figs ). Pronotum with pale mesal band; dark lateral bands cover most of disc. Wing membrane transparent with pale amber tint; veins darker except for pale costa. Femora pale except for narrow black apical band; tibiae dark in proximal fourth and with a small distal dark spot.

Male. Forewing length 10 mm. Hammer reduced to a small, transparent, hairless disc ( Fig. 12 View Figs ). Aedeagal apex pointed in ventral aspect and bearing a prominent pair of ventral, membranous lobes ( Fig. 13 View Figs ); apex angled sharply ventrad in lateral aspect ( Fig. 14 View Figs ), and bearing an obscure V-shaped dorsal keel composed of divergent, broken lines ( Fig. 15 View Figs ). Hooks slender with long acute tips.

Female. Unknown.

Larva. Unknown.

Etymology. The species name, based on Rio Tempisquito, is used as a noun in apposition.

Diagnosis. This species does not appear to be closely related to others known from Mesoamerica, but is more similar to the Ecuadorian species, A. cajas Zúñiga & Vimos, 2006 ( Zúñiga et al. 2006) and the Colombian species A. otun Stark & Zúñiga, 2007 ( Zúñiga et al. 2007). The new species is distinguished from both on the basis of pigment pattern, the prominent ventral membranous lobes, the dorsal keel, and the obscure hammer. In Stark (1998) the new species will key to couplet 9 where a choice of A. varilla could be forced, despite conspicuous differences in aedeagal structure.
