Length: 5 mm (Fig. 28 ). Head (Fig. 28 a , b ): frons 1/4 of head width; gena 1/7 of head height; three reclinate inner orbital setae uppermost reclinate orbital pair slightly convergent, and two proclinate orbital setae; ocellar setae absent; outer vertical seta present; fronto-orbital plate pale brassy-gold; fronto-orbital plate with short blonde hairs interspersed among frontal setae; parafacial brilliant silver; facial ridge bare; palpus apically clubbed and slightly upturned; 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 including gena gold tomentose; occiput gold tomentose. Thorax (Fig. 28 a , c ): brassy-gold tomentose, with four distinct thoracic stripes outer pair broken across suture; plumose hairs absent from disc of scutum; chaetotaxy: 5-6 postpronotal setae, basal setae arranged in a straight line; supra-alar setae 2:3; intra-alar setae 2:3; dorsocentral setae 3:3; acrostichal setae 3:3; katepisternum with three setae; meron lacking plumose hairs with 9-12 typical meral 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 hair covering; both midleg and hindleg with yellow coxa, and remainder of both legs yellow-brown appearing dark brown due to hair covering; anterior leg tibia with irregular sized fringe of equally spaced setae along anteroventral surface, with one posterodorsal setae. Wings : basicosta ivory white; all veins bare, with only one setula at base of R4+5; calypters pale white translucent. Abdomen (Fig. 28 a , c ): ground color yellow-orange; ST1+2 brown over medial 50%, with yellow ventrolaterally, extending into a longitudinal middorsal brown stripe bisected by a brown band along posterior edge of T3 and T4 entirely brown dorsally; T1+2-T4 with dense gold tomentum extending over entire tergite; T5 entirely yellow, covered with gold tomentum; marginal setae present on T4 and T5; median discal setae absent. Male. Unknown at this time. Diagnosis Telothyria gloriasihezarae 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, three postsutural intra-alar setae, and T5 yellow with gold tomentum. Etymology Telothyria gloriasihezarae sp. n. is named in recognition of Gloria Sihezar's outstanding work on the team that conducts the caterpillar and parasite inventory from ACG's Estacion Biologica San Gerardo. Distribution Costa Rica, ACG, Alajuela Province, 575 m elevation. Ecology Telothyria gloriasihezarae sp. n. has been reared two times from a single species of Lepidoptera in the family Crambidae : Desmia Janzen03 , in rain forest.
