Length: 10-11mm (Fig. 11 ). Head (Fig. 11 b ): frons narrow, 1/5 of head width; gena 1/8 of head height; two reclinate orbital setae; anteriormost reclinate orbital almost equal to uppermost frontal seta; ocellar setae absent, or apparently absent; outer vertical seta absent; fronto-orbital plate brassy-gold throughout; fronto-orbital plate with short black hairs interspersed among frontal setae; parafacial brassy-gold, almost concolorous with fronto-orbital plate; facial ridge bare; palpus long slender digitiform with slight upward turn apically, sparsely haired along outer margin; arista orange-brown, smoothly tapered, microtrichia at most 3X as long as width of arista, concolorous with postpedicel; postpedicel only 30% orange, directly adjacent to pedicel; postocular region behind margin of eye including gena gold tomentose; occiput dark grey to silver tomentose. Thorax (Fig. 11 a , c ): pale brassy tomentose, with four thick and distinct dorsal stripes, bearing a basal dark dorsomedial stripe on postsutural scutum directly adjacent to scutellum; plumose blonde hairs absent from disc of scutum, punctuated on anepisternum at base of postpronotum with a spot of long brown plumose hairs, dorsally thorax densely covered in black hairs; 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 4:4; katepisternum with three setae. Scutellum dark brown ground color with brassy tomentosity along margin 20%; 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 regular non-plumose black hairs below basal scutellar setae. Legs : all legs dark brown ground color; anterior leg tibia with regular fringe of equally spaced setae along anteroventral surface, one posterodorsal setae. Wings : basicosta brown; all smoky-brown slightly infuscate all veins bare, with only one setula at base of R4+5; calypters brassy brown, lower calypter with a narrow yellow fringe, upper calypter with a narrow brown fringe. Abdomen (Fig. 11 a , c ): ground color bright orange, with orange to maroon spots apparent when viewed dorsally; ST1+2 maroon over dorsomedial 40%, T3 and T4 each with only some dark brown spots present dorsomedially; light silver tomentum along T3-T5, extending over entire tergite appearing to have a silver sheen when viewed with under certain angles of light; T5 orange ground color with a slightly darker apex and a light silver tomentum; median marginal setae present only on T4 and T5; median discal setae absent. Male terminalia (Fig. 11 d , e , f ): Sternite 5 with a wide deeply excavated median cleft, smoothly V-shaped, margins covered in dense pollinosity; lateral lobes of sternite rounded apically, with a group of strong setulae along outer margins; basal section of sternite 5 subequal to slightly longer than length of apical lobes. Cerci in posterior view sharply pointed triangular sharply widening to a rectangular shoulder along the basal section, equal in length to surstyli, fused along entire length; in lateral view, with a slight downward angle on apical 1/3; when viewed dorsally entire genital capsule can be said to be quite hirsute bearing several strong setulae throughout. Surstylus in lateral view, almost equilateral along its length rounded and downwardly curved at tip, appearing digitiform; surstylus appearing fused with epandrium; when viewed dorsally surstyli appear slender with a slight inward curve at apices. Pregonite short and not very well developed, apically rounded, bare. Postgonite, elongate and slender, sharply pointed at its tip, subequal in length to pregonite. Basiphallus long and slender, as a short humplike process. Distiphallus subequal in length to basiphallus and tubular, slightly pointed at apex. Female. Unknown at this time. Diagnosis Very distinctive species of Telothyria can be distinguished from its congeners by the following combination of traits: ocellar setae absent, or apparently absent, fronto-orbital plate and parafacial pale brassy-gold, with four thick and distinct dorsal stripes, bearing a basal dark dorsomedial stripe on postsutural scutum directly adjacent to scutellum, plumose blonde hairs absent from disc of scutum, punctuated on anepisternum at base of postpronotum with a spot of long brown plumose hairs, dorsally thorax densely covered in black hairs, katepisternum with three setae, and entire abdomen bright orange. Etymology Telothyria clavata sp. n. From the Latin noun, " clavus " for the stripes on the tunics of Roman senators, in reference to the uniquely bold dorsal stripes.
