Description

Male. Length: 7-10 mm (Fig. 41). Head (Fig. 41 b): frons narrow, 1/6 of head width; gena 1/8 of head height; two reclinate orbital setae; anteriormost reclinate orbital four times longer than uppermost frontal seta; ocellar setae present but so small as to appear absent; outer vertical seta absent; fronto-orbital plate brassy gold, ocellar triangle slightly darker than vertex; fronto-orbital plate with short blonde hairs interspersed among frontal setae; parafacial pale, with a very light silver tomentosity visible under certain angles; facial ridge bare; palpus with a slight spatulate club at apex, sparsely haired along outer margin; arista orange-brown smoothly tapered, microtrichia at most as long as width of arista; postpedicel orange over more than 50% of surface; postocular region behind margin of eye upper 3/4 gold, with lower 1/4 including gena silver tomentose; upper half of occiput gold tomentose. Thorax (Fig. 41 a, c): golden tomentose, with four distinct dorsal stripes; entire thorax covered in dense plumose blonde hairs; chaetotaxy: 6-7 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 two setae. Scutellum ranging from golden 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 with yellow ground color throughout, tibia and tarsal segments appearing darker due to hair covering; midleg with yellow coxa and femur, tibia light yellow-brown appearing darker due to hair covering and dark brown tarsal segments; hindleg with yellow coxa and proximal 1/3 of femur, almost entirely dark brown extending from distal 2/3 of femur to tarsal segments; anterior leg tibia with regular fringe of equally spaced setae along anteroventral surface, with two strong posterodorsal setae. Wings: basicosta pale ivory, darkening to brown basally; dorsally with 1-2 setulae at base of R4+5; calypters pale white translucent, fringe only slightly more opaque than remainder of calypter. Abdomen (Fig. 41 a, c): ground color yellow-orange; ST1+2 brown over 50%, with yellow ventrolaterally, extending into a longitudinal middorsal brown stripe up to posterior edge of T4; T3 and T4 each with dense gold tomentum along anterior marginal 10%, thinning and extending over remainder of tergite; T5 entirely orange with gold tomentum; median marginal setae present only on T4 and T5; median discal setae absent. Male terminalia (Fig. 41 d, e, f): Sternite 5 with a wide deeply excavated median cleft, smoothly V-shaped, margins covered in dense pollinosity; lateral lobes of sternite pointed apically, with a small group of strong setulae along outer margins; basal section of sternite 5 subequal to slightly shorter than length of apical lobes. Cerci in posterior view sharply pointed and slender, abruptly widening to a moderate almost rectangular shoulder along the basal section, equal in length to surstyli, fused along entire length; in lateral view, with a smooth regular downward curve along apical 2/3rds; several strong widely spaced setulae along basal 1/3rd. Surstylus in lateral view, almost equilateral along its length rounded at tip, digitiform; surstylus appearing fused with epandrium; when viewed dorsally surstyli appear slender with an inward bend. Distiphallus 2X as long as basiphallus and tubular, slightly pointed at apex.

Female. Length: 5-9 mm (Fig. 42). Head (Fig. 42 b): as in male with the following exceptions: fronto-orbital plate 50% gold; parafacial brilliant silver; frons 1/5 of head width; three inner reclinate orbital setae; two proclinate orbital setae; outer vertical seta present; postocular region behind margin of eye upper 1/4 gold, with lower 3/4 including gena silver tomentose; upper half of occiput gold tomentose. Thorax (Fig. 42 a, c): katepisternum with three setae; meron densely covered in plumose hairs as in male but with the addition of 2-4 typical meral setae. Legs: foreleg with yellow ground color throughout; midleg with yellow coxa and proximal 1/5 of femur with brown tibia and tarsal segments; hindleg with yellow coxa, proximal 1/3 of femur yellow and remainder almost entirely dark brown extending from femur to tarsal segments. Wings: as in male except ventrally R4+5 bearing 2-7 setae. Abdomen (Fig. 42 a, c): ground color brown on ST1+2 and T3 with small patches of orange laterally; T4 entirely brown ground color; T5 entirely orange with gold tomentum; T3 with one pair of median marginal setae and T4, T5 with a complete row of marginal setae.

Diagnosis

Telothyria relicta can be distinguished from all other Telothyria by the following combination of traits: ocellar setae present but so small as to appear absent, postpedicel mostly orange, parafacial gold, entire thorax covered in dense plumose blonde hairs, katepisternum with two setae, underside of scutellum bearing plumose blonde hairs below basal scutellar setae, legs yellow, abdominal ground color yellow-orange, and T5 entirely orange with gold tomentum.

Distribution

Costa Rica, ACG, Alajuela Province, 123-560 m elevation.

Ecology

Within the ACG inventor, Telothyria relicta has been reared seven times from three species of Lepidoptera in the family Crambidae : Desmia tages (Cramer, 1777), Desmia benealis DHJ03, and Desmia ploralis DHJ10 in rain forest and dry-rain lowland intergrade.
