Paratypes.

Ten female and five male specimens mounted on individual points (CNC). The pins where two of the female specimens are mounted also have a gel capsule each, with a few additional (unmounted) specimens. All paratypes either from the same holotype locality or the following three localities, all in ACG: 1) Leonel, 510m, 10.99637N, - 85.40195W, Sector Pitilla, Guanacaste province; 2) Casa Roberto, 520m, 11.01095N, - 85.42094W, Sector Pitilla, Guanacaste province; 3) Sendero Perdido, 620m, 10.8794N, - 85.38607W, Sendero San Cristobal, Alajuela Province.

Diagnosis.

Dolichogenidea alejandromasisi can be recognized by its black to brown metafemur, comparatively narrower T1 (usually T1 L medially 2.0-3.0 × T1 posterior W), more quadrate T2 (T2 posterior W 1.30-1.90 × T2 L medially) and host being Depressariidae . D. rogerblancoi shares those features and is very similar morphologically, but it differs from alejandromasisi by having shorter F1 L, relatively less quadrate T2 (T2 posterior W 1.6-2.1 × T2 L medially) and relatively broader pterostigma. The two species parasitize different hosts (although in the same genus Antaeotricha ), but alejandromasisi tends to be found at higher 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 (with small dark brown spots), 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 renselariana (Stoll, [1781]) ( Depressariidae ). This is the only species of Dolichogenidea parasitizing that species of caterpillar in ACG, with 87 records out of 1,132 rearings.

Distribution.

Costa Rica, ACG, Sectores San Cristobal & Pitilla, 500-620 m. Rain forest ecosystem.

Molecular data.

This species is represented in BOLD by 78 sequences, which belong to BINBOLD:ABX6174.

Etymology.

Dolichogenidea alejandromasisi is dedicated to Alejandro Masis Cuevillas, Director of Area de Conservación Guanacaste, in recognition of his decades of protection and biodevelopment of the forests occupied by this wasp.
