Anacroneuria totumas sp. n.

( Figs. 16-20 View Figs )

Material examined. Holotype ♂, Panama, Chiriqui, Totumas Cloud Forest , lodge, 08 ° 53.060’ N, 82 ° 41.068’ W, 1920 m, 19-25 June 2011, E. Fuller ( USNM) GoogleMaps . Paratypes: Costa Rica: Puntarenas, Rio Bellavista , ca. 1.5 km NW Las Alturas, 1400 m, 10-11 August 1990, R. Holzenthal, R. Blahnik, F. Munoz, 1♂ ( BPSC) . San Jose, tributary Quebrada Caraiges , 3.6 km SW La Legua, 1650 m, R. Holzenthal, K. Kjer, F. Quesada, 2♂ ( BPSC) .

Adult habitus. General color brown patterned with yellow-brown. Head with dark lappets, antennae and a dark band extends from behind ocelli forward to M-line; dark band expanded laterally along M-line, and interrupted by a pale interocellar spot ( Fig. 16 View Figs ). Pronotum dark over most of disc, but with a slender pale median band. Wings pale brown, veins brown except for C and apical half of SC. Femora pale in proximal half and dark brown in distal half; fore and mid tibiae brown, hind tibiae with pale transverse median band.

Male. Forewing length 20 mm. Hammer a low, mound-like structure ( Fig. 17 View Figs ). Aedeagal apex simple ( Figs. 18-19 View Figs ); ventroapical aspect with a large pair of membranous lobes overlying darkly sclerotized lateral margins ( Fig. 18 View Figs ); dorsal keel absent, lateral margins slightly convergent to truncate apex ( Fig. 20 View Figs ). Hooks slender.

Female. Unknown.

Larva. Unknown.

Etymology. The species name, based on the type locality at the Mount Totumas Cloud Forest, is used as a noun in apposition.

Diagnosis. This species keys to couplet 11 in Stark (1998) where A. acutipennis Klapálek, 1923 and A. equisita , a pair of species with trilobed aedeagal apices are the options. Because the new species has a simple aedeagal apex without lateral lobes, neither of these choices are viable. The aedeagal apex of the new species is generally similar to that of A. varilla , a much smaller species (male FWL = 9-10 mm) known from Costa Rica and Panama ( Stark 1998).
