Length: 6 mm (Fig. 10 ). Head (Fig. 10 b ): frons narrow, 1/3 of head width; frontal vitta narrow yet prominent and visible 1/12 head width; gena 1/10 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 along upper third inclusive of ocellar triangle; 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, proximal to pedicel; postocular region behind margin of eye upper 1/3 gold, with lower 2/3 including gena silver tomentose; upper 1/3 of occiput gold tomentose. Thorax (Fig. 10 a , c ): light brown ground color covered with pale gold tomentum, with four distinct thoracic stripes outer pair broken across suture; plumose blonde 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 2:2; dorsocentral setae 3:3; acrostichal setae 3:3; katepisternum with three setae; meron lacking plumose hairs with 4-5 typical meral setae. Scutellum brassy-gold tomentose; underside of scutellum bearing plumose blonde hairs; 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 ground color yellow over coxa, femur, and tibia, tarsal segments appearing darker due to covering of dark hairs; midleg and hindleg with yellow coxa, and remainder dark brown entirely; anterior leg tibia with irregularly sized, tapered fringe of equally spaced setae along basal half of anteroventral surface, one posterodorsal seta. Wings : basicosta ivory white; all veins bare, with only one setula at base of R4+5; calypters pale white translucent. Abdomen (Fig. 10 a , c ): ground color mostly brown with yellow-orange present ventrolaterally; ST1+2-T4 with gold tomentum at tergal margin changing to silver tomentum extending over up to 50% of tergite; T5 brown along anterior margin with yellow apically, tergite covered with silver tomentum along anterior 50%; marginal setae present on T4 and T5; median discal setae absent. Male. Unknown at this time. Diagnosis Telothyria carolinacanoae sp. n. can be distinguished from all other Telothyria by the following combination of traits: ocellar setae absent, plumose blonde hairs absent from disc of scutum, katepisternum with three setae, two postsutural intra-alar setae, and T1+2-T4 with gold tomentum at tergal margin changing to silver tomentum extending over up to 50% of tergite, ground color mostly brown with yellow-orange present ventrolaterally. Etymology Telothyria carolinacanoae sp. n. is named in recognition of Carolina Cano's outstanding work on the team that conducts the caterpillar and parasite inventory from ACG's Estacion Biologica San Gerardo. Distribution Costa Rica, ACG, Guanacaste Province, 292m elevation. Ecology Telothyria carolinacanoae sp. n. has been reared once from a single species of Lepidoptera in the family Crambidae : Herpetogramma phaeopteralis , in rain forest.
