Diagnosis

Teloneria ladyae sp. nov. and T. juceliae sp. nov. are very similar in general color, both with thorax yellowish-brown sub-shiny with dorsal brown and yellow areas; postpronotal lobe, notopleura, anepisternum, anepimeron and katepisternum partially yellow; and femora yellow with distal fourth black. These species also bear an inner vertical seta one third or more shorter than the length of the outer vertical seta. Exclusive characters of T. ladyae sp. nov. include anterior margin of frons very convex, three well-developed fronto-orbital setae, hind trochanter with ventral patch of setulae and thorax mostly yellow, with two suprahumeral dark brown spots and one presutural median brown line. Within Neriidae , T. ladyae sp. nov. is the only species in which males bear strong mid legs, represented in the mid tibia thickening distally and mid tarsomeres with ventral setae.

Etymology

The specific epithet ‘ ladyae ’ is dedicated to T.A. Sepúlveda’s mother, Luz Lady Villa Toro.

Description

Male (holotype)

MEASUREMENT. Body length 6.3 mm. Wing length 5.7 mm and width 1.4 mm.

HEAD ( Fig. 5A ). Rounded. First flagellomere ovate, with acute apex. Anterior margin of frons projecting over small antennal bases and between antennae, surpassing anterior margin of parafacial; outer vertical seta aligned with three subequal postocular setae; occipital setae very thin.

THORAX ( Fig. 5C ). Dorsal median brown line very pale, scutellum dark brown dorsally and yellow laterally; anterior notopleural seta subequal to posterior notopleural seta. Proepistermun yellow. Ventral katepisternal seta hair-like and short. Fore and mid coxae yellow, hind coxa brown. Femora yellow with brown distal fourth, slightly paler on fore femur; fore femur without ventral rows of setae; fore tarsomeres without ventral setae.

ABDOMEN. Dark brown except yellow lateral of syntergite 1 + 2 at proximal half; syntergite 1 + 2 with several long setulae laterally on posterior half. Syntergosternite 8 protruding basally and dorsally, with seven setae; epandrium only slightly longer than syntergosternite 8, reaching anterior half of

third segment ventrally; surstylus narrow linear; cercus broad linear, tapering distally toward inner margin; length of cercus half length of epandrium and twice length of surstylus ( Fig. 2D ).
