Twelve female and four male specimens ( CNC), the pin where one of the male specimens is mounted also has a gel capsule with a few additional (unmounted) specimens. All paratypes either from the same holotype locality or from Sendero Carmona, 670m, 10.87621N, - 85.38632W, Sector San Cristobal, Alajuela province. Voucher codes: DHJPAR0049206, DHJPAR0053702, DHJPAR0053756, 12 –SRNP– 75869, 12 –SRNP– 76060, 13 –SRNP– 4390.


Dolichogenidea rogerblancoi  can be recognized by its black to brown metafemur, comparatively narrower T1 (usually with T1 L medially 2.0-3.0 × T1 posterior W), more quadrate T2 (T2 posterior W 1.6-2.1 × T2 L medially) and host being Depressariidae  . D. alejandromasisi  shares those features and is very similar morphologically, but it differs from rogerblancoi  by having longer F1 L, relatively more quadrate T2 (T2 posterior W 1.3-1.9 × T2 L medially) and relatively narrower pterostigma. The two species parasitize different hosts (although in the same genus Antaeotricha  ), but rogerblancoi  tends to be found at lower 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 (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 light 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  radicalisDHJ01 ( Depressariidae  ). This is the only species of Dolichogenidea  known to parasitize that species of caterpillar in ACG, with 24 records out of 243 reared caterpillars of this species. It does not parasitize any of the other ACG species of the " Antaeotricha radicalis  " species complex.

Dolichogenidea rogerblancoi  is dedicated to Roger Blanco Segura of Area de Conservación Guanacaste, co-coordinator of ACG Research & Subdirector of ACG Area Silvestre Protegido, in recognition of his many decades of protection and biodevelopment of the forests occupied by this wasp.
