Dolichogenidea yeimycedenoae  can be recognized by its mesofemur mostly dark brown, comparatively narrower T1 (T1 L medially more than 2.5 × T1 posterior W), relatively more quadrate T2 (T2 posterior W 1.5 × T2 L medially) and host being Depressariidae  . The mesofemur color would separate this species from D. alejandromasisi  and D. rogerblancoi  . However, D. yeimycedenoae  is very similar morphologically to D. genuarnunezi  , with only slight differences in pterostigma L/W, 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.


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.

Reared from Antaeotricha  Janzen126 ( Depressariidae  ). This is the only species of Dolichogenidea  known to parasitize that species of caterpillar in ACG, with one record out of three reared caterpillars of this species.

Dolichogenidea yeimycedenoi  is dedicated to Yeimy Cedeño Solis of Moravia & Ostional, Costa Rica, in recognition of her dedication to understanding and explaining the BioAlfa project to render Costa Rica bioliterate, to COP14 of the Convention for Biological Diversity in October 2018.


The holotype is a teneral specimen, and thus its coloration (as shown in Fig. 8, which contains only images of the holotype) is not the typical coloration found in the species (body mostly black to dark brown body). However, we still selected that specimen to be the holotype because the other available specimens are missing several legs and/or antennae, and also are mostly covered by dirt. The specimen we selected as the holotype, although having a much lighter coloration than the rest, is the best preserved from the series, is not missing any body part, and thus is the best choice to characterize the species (except for the body coloration, which anyways has no diagnostic value as all described species in the Dolichogenidea carlosmanuelrodriguezi  group have the same black coloration).
