TRICHADENOTECNUM TAMBOPATENSE View in CoL SP. NOV.
Material examined: Holotype. Male. Peru: Madre de Dios. Río Tambopata Reserved Zone , 30 km SW Puerto Maldonado, 290 m, 10.ix.1984, T. L. Erwin et al. ( SI) . Paratypes. 1 male, 2 females, same data as holotype, 4.v.1984 ( SI) ; 1 male, same locality, 6.ix.1984 ; 2 males, same data as holotype ( SI) ; 1 male, same locality as holotype, 14.ix.1984 ( SI) .
Etymology: The specific epithet is taken from the type locality of this species.
Description: Male. Head. White in ground colour; vertical and orbital markings brown; coronal suture black; frontal suture bordered with narrow pale brown line dorsally; frons with pair of pale brown lines at middle; gena brown in ventral half with white spot ventrally; eye black, IO/D = 1.0; ocelli white, ocellar field pale; antennal socket bordered with narrow brown band; postclypeus with c. six rows of brown spots, ventral margin blackish brown; anteclypeus brown. Antenna pale brown. Mouth parts pale brown; 4th segment of maxillary palpus darker.
Thorax. Prothorax brown. Mesonotum white in ground colour; each lobe of scutum with large brown marking, marking on anterior lobe bilaterally divided by narrow white line, marking on lateral lobe divided in two by narrow white transverse line; scutellum brown, antero-lateral corner blackish brown; postnotum pale brown. Metanotum brown, anterior lobe paler, lateral lobe with white spot posteriorly; anterolateral corner of scutellum blackish brown. Meso- and metapleurites brown except membranous region and ventral region of epimeron white.
Legs. Fore- and middle femur, tibiae and tarsi unavailable. All coxae, trochanter and hind leg brown, distal ends of hind femur and tibiae paler.
Forewing ( Fig. 1D View Figure 1 ). Spots in cell a 1 faint, indistinct. Opposing spots in cell r indistinct except for very small posterior spot. Proximal band represented by triangular or semicircular markings just below fork of M + Cu and irregular-shaped marking on basal section of Rs. Distal band indistinct except for faint brown tinge in cell r 5. Spot on roof of cell m 3 small, only distinct on distal Rs-CuA fork. Submarginal spots distinct only for large spots in cells r 5, m 1 and m 2. Marginal clouds indistinct except for brown spots on distal ends of vein R 2+3, R 4+5 and M 1. Hindwing. Hyaline, cell CuP with faint brown markings at distal end; veins brown.
Abdomen. White, sparsely with minute blackish brown spots ventrally. Terminalia. Anterior margin of 8th sternum ( Fig. 3C View Figure 3 ) deeply incised by membranous region medially. Epiproct lobe ( Fig. 3B View Figure 3 ) longer than wide, nearly parallel sided and with smoothly rounded dorsal margin, posterior surface shallowly concave. Paraproct ( Fig. 3A View Figure 3 ): ventro-lateral band absent. Hypandrium ( Fig. 3C View Figure 3 ): left and right processes conical, directed posteriorly, basally arranged with many processes of variable size; basal and distal parts of median tongue strongly expanded laterally, apical margin slightly hollowed, with several fine and rather long setae, ventral surface covered with denticles distally and antero-laterally. Phallosome ( Fig. 3D View Figure 3 ): posteriorly with pair of conical processes medially. Phallobase parallel sided posteriorly, then narrowing to truncated anterior end.
Length. B 1.8–2.0; FW 2.3–2.4; HW 1.7–1.8.
Female (available from dissected females only). Colour and general morphology almost as in male. IO/D = 2.1. Fore and middle legs brown, distal ends of femur white, tibiae paler. Genitalia. Egg guide of subgenital plate ( Fig. 4A View Figure 4 ) gradually narrowing to slightly arched distal margin, medially with membranous region; pigmented arms closely approximated basally, antero-internally with extension of sclerite. External valve of gonapophyses ( Fig. 4B View Figure 4 ) small, internal end not reaching internal margin of dorsal valve, posteriorly with weak posterior lobe. Internal plate as in Fig. 4C View Figure 4 .
Length. B (unavailable); FW 2.1–2.2; HW 1.6–1.7.
