Diagnosis.

Dolichogenidea genuarnunezi can be recognized by its mesofemur mostly dark brown, comparatively narrower T1 (T1 L medially more than 2.0 × T1 posterior W), relatively more quadrate T2 (T2 posterior W 1.6 × T2 L medially) and host being Depressariidae . The mesofemur color would separate this species from D. alejandromasisi and D. rogerblancoi . However, D. genuarnunezi is very similar to D. yeimycedenoae , with only slight differences in pterostigma L/W ratio, as well as proportions of posterior ocellar line, lateral ocellus diameter and ocular ocellar line (see key above for details). The variation of those characters is very small, to the point that both species are very similar morphologically. However, they parasitize different host species, and also differ significantly molecularly (available DNA barcodes are 4.54% different). Additionally, the two species have been found at different altitudes.

Description.

Body color: head and mesosoma black, metasoma black to dark brown; palpi, metatibial spines, tegula and most of humeral complex white-yellow; legs mostly orange-yellow, except for mesofemur and metafemur mostly brown, and apical 0.1-0.2 of metatibia and metatarsus brown; wing venation mostly white or transparent, except for fore wing veins R1, r, 2RS and 2M which are brown, pterostigma mostly brown but with small light spot at base. Anteromesoscutum mostly with setae and sculptured with punctures that do not fuse with each other; scutoscutellar sulcus relatively wide and with relatively deep crenulae; scutellar disc smooth and unsculptured, with isolated setae; propodeum mostly setose and with scattered punctures; propodeum areola partially defined on posterior half by longitudinal carinae, transverse carinae partially defined; T1 mostly smooth, with shallow and sparse punctures along lateral margins; T2+ smooth.

Biology.

Reared from Antaeotricha phaeoneura (Meyrick, 1913) ( Depressariidae ). This is the only species of Dolichogenidea known to parasitize that species of caterpillar in ACG, with one record out of 25 rearings.

Distribution.

Costa Rica, ACG, Sector San Cristobal, 500m. Rain forest ecosystem.

Molecular data.

This species is represented in BOLD by one sequence belonging to BINBOLD:ACC1300.

Etymology.

Dolichogenidea genuarnunezi is dedicated to Genuar Roman Núñez Vega of Guadalupe, Costa Rica, in recognition of his dedication to supporting BioAlfa to render Costa Rica bioliterate, constructing CONAGEBIO as a biodiversity biodevelopment-friendly government agency, and constructing Costa Rica’s Biodiversity Clearing House for COP14 of the Convention for Biological Diversity in October 2018.
