description: TRICHADENOTECNUM QUAESITELLUM 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). 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.   
 Abdomen. White, with sparse minute blackish brown spots. Terminalia. Clunial arm (Fig. 22A) developed but very weakly sclerotized, not forming free process apically, basally with membranous lobe ventrally covered with short spines. Anterior margin of 8th sternum (Fig. 22C) smoothly arched, fusion with hypandrium narrow. Epiproct lobe (Fig. 22B) broadened dorsally, wider than long, dorsal margin sinuate, posterior surface slightly concave. Paraproct (Fig. 22A); ventro-lateral band short, triangular; distal process long. Hypandrium (Fig. 22C): outer margin of left process slightly arched, directed posteriorly; right process projected outward, then strongly bent postero-internally near base, its apex not exceeding outer margin of left process; median tongue long, slightly constricted medially, apical margin slightly hollowed, dorsal keel rounded. Phallosome (Fig. 22D): 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.
