TRICHADENOTECNUM ERICIUM View in CoL SP. NOV.
Material examined: Holotype. Male. Mexico: Puebla, c. Xicotepec de Juárez , 20.iii.1983, H. Brailovsky ( UNAM) . Paratypes. 2 males, 1 female, 4 mi W. Jalacingo, Rd. 131, Veracruz, 29.vi.1962, ELM, J. Campbell & F. Hill ( ISU) .
Etymology: The specific epithet is taken from the Latin ericius (= spiny), in reference to the field of spines on the lobes of the clunial arms.
Description: Male. Head. White in ground colour; vertical and orbital markings pale brown; coronal suture black; frontal suture bordered with dark brown band dorsally; frons with pair of brown bands medially and pair of pale circular spots laterally; gena dark brown, dorsal half paler; eye black, IO/D = 0.9; ocelli white, ocellar field black; antennal socket bordered with dark brown band; postclypeus with c. eight rows of pale brown spots at middle, fused with each other ventrally forming a large blackish brown marking, ventro-lateral corner white, lateral margin of postclypeus brown, dorsal margin without marking; anteclypeus brown. Antenna pale brown, pedicel and scape darker. Mouth parts dark brown; third segment of maxillary palpus pale brown.
Thorax. Prothorax brown. Mesonotum white; anterior surface of scutum brown; anterior margin of lateral lobe of scutum black; posterior region of scutum with pair of brown markings at middle; scutellum white, median part and anterior margin brown; postnotum brown. Metanotum brown, with pair of whitish oval spots on posterior regions of lobes of scutum, lateral corner white. Meso- and metapleurites brown with longitudinal white band medially.
Legs. Coxae dark brown; femora brown except middle part of fore and middle femora white; tibiae pale brown, with darker portion near distal ends; tarsi brown.
Forewing ( Fig. 17H View Figure 17 ). Sparsely covered with small spots. Spots in cell a 1 apparent, almost equal in size. Opposing spots in cell r large and distinct. Proximal band narrow, broadly interrupted just beyond fork of M + Cu. Distal band narrow in cell r 5, small in cell r 3. Spot on roof of cell m 3 narrow, narrower in distal half. Submarginal spots apparent; spot in cell r 5 elongate; spots in cells r 1 and m 3 small, almost indistinct. Marginal clouds faint. Hindwing. Hyaline, cell CuP with faint brownish spots in distal half, cell r 3 with few faint spots, cell r 1 with longitudinal faint marking along R1 vein; veins brown.
Abdomen. White, with sparse minute blackish brown spots. Terminalia. Clunial arm ( Fig. 29A View Figure 29 ) long, rather broad, forming rounded free process apically, antero-ventrally with sclerotized lobe covered with short and thick spines. Anterior margin of 8th sternum ( Fig. 29C View Figure 29 ) irregularly indented; fusion with hypandrium rather broad. Epiproct lobe ( Fig. 29B View Figure 29 ) wider than long, dorsal margin almost straight, with conical projection medially, posterior surface almost flat. Paraproct ( Fig. 29A View Figure 29 ): ventro-lateral band short, triangular; distal process short. Hypandrium ( Fig. 29C View Figure 29 ): left process broad, slightly arched, directed postero-internally; right process projected outward, then strongly bent postero-internally near base; median tongue slightly broadened apically, apical margin slightly hollowed, dorsal keel rounded. Phallosome ( Fig. 29D View Figure 29 ): pseudoparameres widely separated, short, almost as long as wide, directed dorsally, apical margin almost straight with small projection internally. Phallobase widest at anterior third, then narrowing to pointed anterior end.
Length. B 2.6–2.8; FW 3.5–3.7; HW 2.7–2.8.
Female. Colour and general morphology almost as in male; eye IO/D = 2.0. Genitalia: Egg guide of subgenital plate ( Fig. 30A View Figure 30 ) slightly widened near distal end, apical margin slightly arched and shallowly hollowed at middle; dorsal surface of egg guide sclerotized laterally; body of subgenital plate with pair of triangular extensions antero-medially. Dorsal valve of gonapophyses ( Fig. 30B View Figure 30 ) with short distal process; posterior lobe of external valve not strongly projected posteriorly. Internal plate as in Figure 30C View Figure 30 .
Length. B 3.1; FW 3.9; HW 2.8.
