Anacroneuria darien View in CoL , sp. n.

( Figs. 2–7 View FIGURES 2 – 7 )

Material examined. Holotype ♂ ( USNM), Panama: Darién , Darién National Park, field station near to the Perresenico stream, 8° 01' 10.41''N; 77° 44' 17.44'' W, 94 m asl, 17–22 November 2014, R. Salas, PE Gutiérrez Fonseca, light trap. Paratypes: 1♂, 3♀ ( PEGFC). Same location. 1♂, 2♀ ( MIUP). Same location.

Adult habitus. General color yellow. Head yellow, with a small brown spot, very diffuse, between ocelli; antennae brown with base yellow. Pronotum yellow, sides with a soft light brown, and margin yellow. Femora mostly yellow with a dark apical band. Tibiae dark yellow with a dark apical band. Wing membrane transparent, veins yellow. Cerci yellow ( Fig. 2 View FIGURES 2 – 7 ).

Male. Forewing length 9.5–10 mm. Hammer thimble-shaped, with height subequal to apical diameter ( Fig. 3 View FIGURES 2 – 7 ). Aedeagal apex simple, rounded at tip; shoulders project slightly, giving apex a trilobed appearance ( Fig. 4 View FIGURES 2 – 7 ). Lateral aspect of aedeagus with acute tip ( Fig. 5 View FIGURES 2 – 7 ). Ventral membranous lobes large, covering shoulders and most of apex ( Fig. 6 View FIGURES 2 – 7 ). Dorsal keel absent, aedeagal hooks slender.

Female. Forewing length 11.5–12.5 mm. Body coloration similar to male. Subgenital plate with four subequal lobes, median notch deep and V-shaped. Mesal sclerite of sternum 9 V-shaped; sterna covered with short fine setae, lateral areas sparsely clothed with large setae ( Fig. 7 View FIGURES 2 – 7 ).

Nymph. Unknown.

Etymology. The species name, based on the type locality at the Darién National Park, is used as a noun in apposition.

Comments. Anacroneuria darien is similar to A. curiosa Stark 1998 . However, the lateral bands of the pronotum are dark brown in A. curiosa and light brown in A. darien . The aedeagus is also similar to that of A. curiosa , but A. darien lacks a dorsal keel. The aedeagus of A. darien is also similar to the Colombian species A. albimacula Klapálek 1921 ( Stark et al. 1999) , differing in several structures, such as the membranous lobes. These species also differ in their pronotal stripes. In addition, the description of the subgenital plate of A. darien is very similar to the description of Anacroneuria sp. F. by Harper (1992). However, the pronotum of Anacroneuria sp. F. is pale with two narrow sublateral darker stripes.
