Diagnosis

Teloneria juceliae sp. nov. and T. bimaculata have the head elongate and mostly yellow, except for the black frontal vitta and pale brown ventral half of occiput of the latter. Teloneria juceliae sp. nov. and T. ladyae sp. nov. are very similar in general color, both having the thorax yellowish-brown subshiny with dorsal brown and yellow areas; postpronotal lobe, notopleura, anepisternum, anepimeron and katepisternum partially yellow; and femora yellow with distal fourth black. These two species also have the inner vertical seta one third or more shorter than the length of the outer vertical seta. Exclusive characters of T. juceliae sp. nov. include having the first flagellomere pear-shaped with the distal half slightly twisted up ( Fig. 4A ), two well-developed fronto-orbital setae, a broad median dark brown line on the dorsal scutum ( Fig. 4D ) and the male fore femur with three rows of short and thick ventral setae.

Etymology

The specific epithet ‘ juceliae ’ is dedicated to D.S. Souza’s mother, Jucelia Pereira de Santana Souza.

Description

Male (holotype)

MEASUREMENTS. Body length 5.3 mm. Wing length 5.2 mm and width 1.3 mm.

HEAD ( Fig. 4A ).Anterior margin of frons straight; anterior fronto-orbital seta absent; middle fronto-orbital seta positioned near anterior margin of eye and as long as inner vertical seta; posterior fronto-orbital seta lost; outer vertical seta aligned with two subequal postocular setae; occipital setae inconspicuous.

THORAX ( Fig. 4B ). Sub-shiny and partially brown with yellow areas; broad median presutural dark brown line, medially divided near transverse suture; broad median brown postsutural line narrow near transverse suture, widening toward scutellum; scutellum brown dorsally and yellow laterally; anterior notopleural seta subequal to posterior notopleural seta; proepisternum yellow; ventral katepisternal seta hair-like and short. Fore and mid coxae yellow, hind coxa brown. Femora yellow with dark brown distal fourth, slightly paler on fore femur; fore tarsomeres without ventral setae; mid tibia cylindrical and thin; mid tarsomeres without ventral setae; hind trochanter without ventral patch of setulae.

ABDOMEN. Dark brown with several long setulae laterally on posterior half of syntergite 1+2. Syntergosternite 8 not protruded basally and without marginal setae; epandrium only slightly longer than syntergosternite 8, reaching anterior half of third segment ventrally; surstylus narrow linear; cercus broad linear, narrowing distally; length of cercus half length of epandrium and ¾ length of surstylus ( Fig. 2C ).

Variation (males)

Body length 4.6–6.6 mm. Wing length 5.2–6.5 mm and width 1.3–1.7 mm. Inner process of pedicel broad linear to slightly triangular. Anterior margin of frons straight to slightly convex; posterior frontoorbital seta longer than inner vertical seta; postocular setae vary from three long setae to one short plus three long setae or one short seta plus two long setae. Yellow parts of body slightly darker and dorsal longitudinal lines of thorax vary in intensity, especially on anterior half, where these can be yellow to black. Proepisternum brown. Specimens from India (TAUI 674, 681, 672, 675) and two from Thailand (TAUI 1023, 1003) with thorax and pleuron mostly brown. Distiphallus partially sclerotized and flattened, with distal half divided by median membranous area and apex branched in two short membranous spikes.

Female

Body length 4.5–6.3 mm. Ventral katepisternal seta inconspicuous to absent in most females. Fore femur without ventral setae. Oviscape shiny, with dorsal line brown and laterally yellow to entirely brown.

Distribution

India, Thailand.
