TRICHADENOTECNUM QUAESITELLUM View in CoL SP. NOV.

Material examined: Holotype. Male. Mexico: Tamaulipas, 5.1 mi W Gómez Farías , 16.vi.1962, ELM et al. ( ISU).

Etymology: The specific epithet is taken from quaesitum (= specific epithet of Trichadenotecnum quaesitum ) + - ellus (= Latin diminutive). This species is very similar to T. quaesitum but smaller.

Description: Male. Head. White in ground colour; vertical and orbital markings blackish brown; coronal suture black; frontal suture bordered with narrow brown band dorsally; frons with pair of pale brown bands at middle and with pair of circular markings laterally; eye black, IO/D = 0.6; ocelli white, ocellar field black; gena white; antennal socket bordered with brown band; postclypeus with c. eight rows of pale brown spots at middle, fused with each other ventrally forming a large marking, ventro-lateral corner white, lateral margin of postclypeus dark brown, Key to species of the quaesitum group

dorsal margin without marking; anteclypeus pale brown. Antenna pale brown, pedicel and scape darker. Mouth parts pale brown; 4th segment of maxillary palpus brown.

Thorax. Prothorax brown. Mesonotum pale; anterior surface of scutum brown; lateral lobe of scutum with large pale brown marking; scutellum pale brown, median part darker, anterior margin blackish brown; postnotum brown. Metanotum pale brown, with three whitish oval spots on posterior regions of scutal lobes. Meso- and metapleurites brown, with longitudinal white band medially.

Legs. Pale brown; middle and hind coxae, basal half of middle femur and entire hind femur brown, distal tip of hind tibia darker.

Forewing ( Fig. 17D View Figure 17 ). Not extensively covered with tiny spots. Spots in cell a 1 apparent, nearly of equal size. Opposing spots in cell r distinct. Proximal band broad, narrowly interrupted just beyond fork of M + Cu. Distal band distinct. Spot on roof of cell m 3 narrow but distinct. Submarginal spots apparent; spot in cell r 5 elongate. Marginal clouds distinct. Hindwing. Hyaline, cell CuP with faint brownish spots in distal half; veins brown.

Phallosome ( Fig. 22D View Figure 22 ): pseudoparameres widely separated, long, longer than basal width, directed dorsally, apical margin rounded with tiny denticles internally. Phallobase widest at anterior third, then narrowing to pointed anterior end.
