Description
Male.
Length: 7 mm (Fig.
37
).
Head
(Fig.
37
b
): frons narrow, 1/5 of head width; gena 1/12 of head height; three reclinate orbital setae; anteriormost reclinate orbital almost equal to uppermost frontal seta; ocellar setae absent; outer vertical seta absent; fronto-orbital plate brassy-gray throughout; fronto-orbital plate with short blonde hairs interspersed among frontal setae; parafacial brilliant silver; facial ridge bare; palpus short digitiform with slight club apically, sparsely haired along outer margin, slightly denser apically giving apex a darkened tone relative to rest of palpus; arista brown, basally orange, smoothly tapered, with microtrichia at most as long as width of arista; postpedicel only 40% orange, directly adjacent to pedicel; postocular region behind margin of eye upper half gold, with lower half including gena silver tomentose; upper half of occiput brassy-silver tomentose, remainder silver.
Thorax
(Fig.
37
a
,
c
): dark brown ground color, with gold tomentum, with four distinct dorsal stripes, outer pair almost unbroken across suture, and inner pair extending almost to second postsutural dorsocentral seta; thorax laterally covered in dense plumose blonde hairs, dorsally covered in long dark hairs; chaetotaxy: 5 postpronotal setae, basal setae arranged in a straight line; supra-alar setae 2:3; intra-alar setae 1:2; dorsocentral setae 3:3; acrostichal setae 3:3; katepisternum with three setae. Scutellum dark with light gold color along posterior margin; 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
: all legs with an overall light reddish-brown ground color throughout with silver tomentum on posterodorsal surfaces, tibia yellow ground color with dense black hairs giving them an overall dark appearance, tarsal segments appearing dark brown; anterior leg tibia with regular fringe of equally spaced setae along anteroventral surface, and one posterodorsal seta.
Wings
: basicosta beige; all veins bare, with only 1-2 setulae at base of R4+5; calypters pale cinereous translucent, with a narrow yellowish fringe.
Abdomen
(Fig.
37
a
,
c
): ground color dark yellow laterally, with dark brown dorsocentrally and dark brown ventrally; ST1+2 brown medially over central 40%, ST1+2-T5 yellow laterally; T3-T5 with dense sheen of light gold tomentum extending over entire tergite appearing to have a gold sheen when viewed with the naked eye; T5 with orange apically; strong lateral marginal setae on T3; marginal setae absent from T4, row of marginal setae on T5; median discal setae absent.
Male terminalia
: not examined.
Female.
Unknown at this time.
Diagnosis
Telothyria omissa
sp. n.
can be distinguished from all other
Telothyria
by the following combination of traits: ocellar setae absent, fronto-orbital plate brassy-gray, parafacial brilliant silver, postpedicel orange, thorax with four thoracic stripes and three katepisternal setae, abdominal ground color orange with a brownish middorsal stripe, with dark orange lateroventrally from ST1+2-T5, plumose hairs on thorax absent dorsally, and T5 orange apically with gold sheen of tomentum.
Telothyria omissa
differs from
Telothyria obscura
by the absence of median marginal setae on T4, and the underside of scutellum bearing only plumose blonde hairs below basal scutellar setae.
Etymology
Telothyria omissa
sp. n.
From the Latin adjective, "
omissus
" meaning lacking, in reference to the lack median marginal setae on T3 and T4.
Distribution
Mexico, Chiapas, Ocosingo 6km SW, 1400 m elevation.
Ecology
Specimens hand collected once at 1400 m, further ecology not available.
