Diagnosis.

Dolichogenidea carlosmanuelrodriguezi 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. josealfredohernandezi , but the later species is slightly larger and with a slightly more 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 Antaeotricha spurca (Zeller, 1855) ( Depressariidae ). This is the only species of Dolichogenidea known to parasitize that species of caterpillar in ACG, with four records out of 344 rearings.

Distribution.

Costa Rica, ACG, Sector Santa Maria, 820 m. Rain forest ecosystem.

Molecular data.

This species is represented in BOLD by four sequences which belong to BINBOLD:ABZ4155. Interestingly, that BIN may contain more than carlosmanuelrodriguezi , as four other undescribed species (with interim names Janzen51, Janzen156, Janzen 251, and Janzen325) are also included within BOLD:ABZ4155. We have not been able to examine those specimens, and so while it is possible that they are all the same species, we doubt it owing to their different host records. Resolving this potential complex of cryptic species will require future examination of more specimens and is beyond the scope of the present paper.

Etymology.

Dolichogenidea carlosmanuelrodriguezi is dedicated to Carlos Manuel Rodriguez of San Jose, Costa Rica, Minister of Environment & Energy (MINAE), in recognition of his life-long support of ACG and Costa Rican biodiversity conservation overall, as well as being today’s Costa Rican representative for BioAlfa and other biodiversity conservation initiatives for the global Convention for Biological Diversity.
