Description

Male. Length: 8-10 mm (Fig. 9). Head (Fig. 9 b): frons narrow, 1/6 of head width; frontal vitta narrow yet prominent and visible 1/24 head width; gena 1/12 of head height; four reclinate orbital setae; anteriormost reclinate orbital subequal to uppermost frontal seta; ocellar setae reduced, almost absent; outer vertical seta absent; fronto-orbital plate pale brassy-gold throughout; fronto-orbital plate with short blonde hairs interspersed among frontal setae; parafacial pale silver; facial ridge bare; palpus elongate and slender digitiform with slight upward turn apically, sparsely haired along outer margin slightly darkened at tips; arista brown, smoothly tapered, microtrichia short at most as long as width of arista; postpedicel only 1/10 orange adjacent to pedicel; postocular region behind margin of eye upper 3/4 gold, with lower portion including gena silver tomentose; upper 3/4 of occiput gold tomentose. Thorax (Fig. 9 a, c): dark ground color with brassy gold tomentum tomentose, with two pairs of distinct dorsal stripes, outer pair thick and prominent, inner pair extending up to second postsutural dorsocentral seta, when viewed from behind a fifth stripe appears dorsocentrally between postsutural acrostichal setae; thorax covered in dense plumose blonde hairs throughout; chaetotaxy: 4-5 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 4:3; katepisternum with two setae. Scutellum dark brown ground color, slightly gold tomentose; two pairs of strong marginal setae (basal and subapical) and a small pair of crossed apical scutellar setae 1/5th 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 covered in dark hairs giving tibia and tarsal segments an overall dark appearance; midleg and hind leg dark brown ground color, both with yellow coxa; anterior leg tibia with regular fringe of equally spaced setae along anteroventral surface, and 2-3 posterodorsal setae. Wings: basicosta beige/orange brown basally; wings brown slightly infuscate, all veins bare, with only 1-2 setulae at base of R4+5; calypters brassy brown translucent, with a narrow yellowish fringe. Abdomen (Fig. 9 a, c): ground color dark burnt orange to with brown medially apparent when viewed dorsally; ST1+2 dark over dorsomedial 50%, with yellow laterally and dark stripe laterally which continues along T3 and T4; T3-T5 with dense gold tomentum along anterior margin of tergite, diffusing over entire tergite appearing to have a golden sheen when viewed with the naked eye; T5 orange ground color with gold tomentum; median marginal setae on ST1+2-T3 and a complete row on T4 and T5; median discal setae absent. Male terminalia (Fig. 9 d, e, f): Sternite 5 with a narrow deeply cloven median cleft, narrowly V-shaped, margins tomentose; lateral lobes of sternite elongate and subtriangular apically, outer margins covered in strong setae, overall appearance like rabbit ears; basal section of sternite 5 almost 1/2 as long as length of apical lobes. Cerci in posterior view sharply pointed with a strong rectangular shoulder, slightly longer than surstyli, fused along entire length; medial shoulder rounded and smoothly tapered, not abrupt as in other species. In lateral view cerci, with a strong downward bend, along apical 1/2, and several strong widely spaced setae along basal 1/3rd. Surstylus in lateral view narrow and digitiform rounded at tip; fused with epandrium; when viewed dorsally surstyli appearing straight and convergent. Basiphallus long and narrow, distiphallus 3X as long as basiphallus, weakly tapering apically.

Female. Unknown at this time.

Diagnosis

Telothyria bicuspidata sp. n. can be distinguished from its congeners by the following combination of traits: frons narrow, fronto-orbital plate pale brassy-gold throughout, thorax covered in dense plumose blonde hairs throughout, two katepisternal setae, three postsutral intra-alar setae, wings slightly infuscate, calypters brassy brown, and median marginal setae present on ST1+2 and T3.

Etymology

Telothyria bicuspidata sp. n. From the Latin prefix " bi -" meaning two, the noun, " cuspis " meaning tooth, and the suffix " ata " in reference to T5 resembling a pair of canine (cuspid) teeth.

Distribution

Costa Rica, Puntarenas Province, Monteverde 1500 m elevation.
