TRICHADENOTECNUM MIFFY SP. NOV.

Material examined: Holotype. Male. Peru: Madre de Dios. Río Tambopata Reserved Zone , 30 km SW Puerto Maldonado, 290 m, 10.v.1982, T. L. Erwin et al. ( SI) . Paratypes. 1 male, same locality and collectors as holotype ( SI), 7.xi.1983 ; 1 male, same locality and collectors as holotype, 28.xi.1984 ( SI) .

Etymology: The specific epithet is taken from Miffy, a picture book character in the form of a small rabbit, refering to the shape of the epiproct lobe.

Description: Male (available as dissected and partly cleared specimens only). Head. Coloration not discernible; coronal suture black; eye black, IO/D = 1.0; ocelli white, ocellar field black; postclypeus with rows of faint brown spots, ventral margin blackish brown. Antenna pale brown. Mouth parts brown, 4th segment of maxillary palpus blackish brown.

Thorax. Prothorax blackish brown. Mesonotum white; anterior surface of scutum brown with longitudinal white line medially; posterior margin of lateral lobe of scutum pale brown; scutellum pale brown, antero-lateral corner blackish brown; postnotum pale brown. Metanotum white, anterior lobe of scutum and postero-median part of lateral lobe of scutum pale brown; scutellum pale brown, anterolateral corner blackish brown. Meso- and metapleurites brown except membranous region and ventral part of epimeron white.

Legs. Brown; tibiae pale brown with brown spot near distal end; fore and middle femora with pale brown portions at middle and distal end.

Forewing ( Fig. 36F ). Distal spot in cell a 1 large and dark, basal one small and faint. Opposing spots in cell r apparent, anterior one smaller, posterior one large, placed proximal to anterior spot. Proximal band broad but pale in posterior half, strongly constricted at anterior part of cell CuA, broadly interrupted just beyond fork of M + Cu. Median spots sparse. Distal band broad but faint, especially in cell r 5. Spot on roof of cell m 3 small but apparent. Submarginal spots apparent; spot in cell r 5 larger, spot in cell m 3 smaller. Marginal clouds apparent, darker in cell r 5. Hindwing. Hyaline; cell cup with pale brown marking; veins brown.

Abdomen. White, each segment with pale brown band. Terminalia. Clunial arm ( Fig. 42A ) broad basally, then strongly constricted near apex, onionshaped and serrated apically. Anterior margin of 8th sternum ( Fig. 42D ) with broad and deep trapezoidal incision at middle, widely fused with hypandrium posteriorly. Epiproct lobe ( Fig. 42B ) long, much longer than wide, very deeply incised at middle. Hypandrium ( Fig. 42D ): left and right processes long, gradually narrowing to pointed apices, directed posteriorly, then strongly arched, with distal tip directed internally. Phallosome ( Fig. 42E ): posteriorly with pair of rather long conical processes. Phallobase almost parallel sided posteriorly, anterior part gradually narrowing to pointed anterior end.

Length. B (unavailable); FW 2.4–2.5; HW 1.7–1.8.

Female. Unknown.
