Diagnosis.

Dolichogenidea josealfredohernandezi can be recognized by its legs almost entirely orange-yellow (except for small, dark spot on posterior 0.1-0.2 of metafemur). It is very similar to D. carlosmanuelrodriguezi , but the later species is slightly smaller and with a slightly less quadrate T2 (although the variation of those characters is very small, to the point that both species are almost indistinguishable morphologically). However, they parasitize different host species, in different genera, and they also differ in a total of 21 DNA barcode diagnostic characters. 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 small, dark spot on posterior 0.1-0.2 of metafemur, 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 Stenoma Janzen99 ( Depressariidae ). This is the only species of Dolichogenidea known to parasitize that species of caterpillar in ACG, with seven records out of 126 rearings.

Distribution.

Costa Rica, ACG, Sector Rincon Rain Forest, 400m. Rain forest ecosystem.

Molecular data.

This species is represented in BOLD by 5 sequences belonging to BINBOLD:ABA9255.

Etymology.

Dolichogenidea josealfredohernandezi is dedicated to José Alfredo Hernández of Alajuela, Costa Rica in recognition of his dedication to supporting BioAlfa to render Costa Rica bioliterate, representing CONAGEBIO and Costa Rican membership in iBOL (=BioScan at http://ibol.org/site/), and supporting conservation biodevelopment of ACG.

Comments.

Dolichogenidea josealfredohernandezi is very similar to D. carlosmanuelrodriguezi and we have not yet located a good morphological character to distinguish them. However, they parasitize quite different hosts on very different plants and their DNA barcodes are also very different (3.4% base pairs).
