Male. Length: 6 mm (Fig. 38). Head (Fig. 38 a, b): frons narrow, 1/5 of head width; gena 1/10 of head height; four reclinate orbital setae uppermost reclinate orbital pair slightly convergent; anteriormost reclinate orbital shorter than uppermost frontal seta; ocellar setae absent; outer vertical seta absent; ocellar triangle and fronto-orbital plate pale brassy-gold; fronto-orbital plate with short blonde hairs interspersed among frontal setae; parafacial dull gray-silver; facial ridge bare; palpus digitiform, apically terminating in a small bulbous club; arista brown, smoothly tapering to apical 1/8, microtrichia at most 1.5X as long as width of arista; postpedicel orange over at most 30% of surface; postocular region behind margin of eye upper half gold, with lower half including gena silver tomentose; upper half of occiput gold tomentose. Thorax (Fig. 38 a, c): brassy-gold tomentose, with two distinct outer dorsal stripes, and two short inner stripes; thorax covered in dense plumose blonde hairs laterally, absent dorsally; chaetotaxy: five postpronotal setae, basal setae arranged in a straight line; supra-alar setae 2:3; intra-alar setae 2:2; dorsocentral setae 3:3; acrostichal setae 3:3; katepisternum with three setae. Scutellum brassy-gold tomentose; two pairs of strong marginal setae (basal and subapical) and a small pair of crossed apical scutellar setae 1/8-1/10th as long as subapical scutellars; basal scutellar setae subequal in length to subapical setae; subapical setae straight; underside of scutellum bearing plumose blonde hairs below basal scutellar setae. Legs: foreleg brown coxa and proximal half of femur, yellow with ground color extending from distal half of femur, tarsal segments darkened by vestiture of microsetulae; both midleg and hindleg with yellow coxa, and remainder dark brown entirely; anterior leg tibia with smoothly tapering fringe of equally spaced setae along anteroventral surface, and two posterodorsal setae. Wings: basicosta ivory/beige; all veins bare, with only one setula at base of R4+5; calypters pale white translucent with narrow pale yellow fringe. Abdomen (Fig. 38 a, c): ground color yellow-orange; ST1+2 brown over medial 30%, with yellow ventrolaterally, extending into a longitudinal middorsal brown stripe bisected by a brown band along posterior edges of T3 and T4; T1+2-T4 with pale silver tomentum extending over entire tergite, anterior margin of tergites beige tomentose; T5 entirely yellow, bearing some beige colored tomentum; marginal setae present on T4 1/2 as long as those present on and T5; median discal setae absent. Male terminalia: not examined.

Female. Unknown at this time.


Telothyria osvaldoespinozai sp. n. can be distinguished from all other Telothyria by the following combination of traits: ocellar setae absent, plumose hairs absent from disc of scutum, katepisternum with three setae, two postsutural intra-alar setae, underside of scutellum bearing plumose blonde hairs below basal scutellar setae, and T5 yellow with silver tomentum.


Telothyria osvaldoespinozai sp. n. is named in recognition of Osvaldo Espinoza’s outstanding work on the team that conducts the caterpillar and parasite inventory from ACG’s Estación Biológica San Gerardo.


Costa Rica, ACG, Alajuela Province, 96 m elevation.


Telothyria osvaldoespinozai sp. n. has been reared once from a single species of Lepidoptera in the family Crambidae : Herpetogramma phaeopteralis ( Guenée, 1854), in rain forest.
