Anacroneuria laru , sp. n.

( Figs. 8–13 )

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♂, 2♀ ( PEGFC). Same location. 1♂, ( MIUP). Same location.

Adult habitus. Head with dark brown lateral stripes, mid stripe yellow; stripe patterns extend to the pronotum, antennae evenly dark brown. Pronotum with median stripe yellow and lateral stripes dark brown. Fore femora banded in two sections, base section yellow and apical section dark. Most of mid and hind femora yellow, but apical ends dark. Fore tibiae dark, mid and hind light brown, but with a dark apical band. Wing membrane and veins dark brown. Cerci lightly brown at the base ( Fig. 8 ).

Male. Forewing length 7–8 mm. Hammer thimble-shaped, height more than apical diameter ( Fig. 9 ). Aedeagal apex long and slender, scoop-shaped with rounded tip ( Fig. 10 ). Lateral aspect of aedeagus spoon-shaped, distinctively arched ( Fig. 11 ). Ventral membranous lobes small ( Fig. 12 ). Dorsal keel absent, hooks slender.

Female. Forewing length 9 mm. Body coloration similar to male. Subgenital plate bilobed, lobes about equal in length, with median notch V-shaped. Mesal field of sternum 9 uniformly covered with moderately long pale setae ( Fig. 13 ).

Nymph. Unknown.

Etymology. Species name is in honor to biologist Luis Alonso Ramírez Ulate, of initials “ laru ”, for his outstanding contribution to the organization and consolidation of Macrolatinos, a Latin American network of aquatic scientists.

Comments. The aedeagus of this species is similar to the Mexican species A. hoogstraali Jewett, 1958 , with the apex spoon-shaped in lateral view and with small membranous lobes ( Stark & Kondratieff 2004). However, the pigment patterns in the pronotum and head of these species are markedly different.
