TRICHADENOTECNUM BOS SP. NOV.

Material examined: Holotype. Male. Peru: Madre de Dios. Río Tambopata Reserved Zone , 30 km. SW Puerto Maldonado, 290 m, 6.ix.1984, T. L. Erwin et al. ( SI).

Etymology: The specific epithet is taken from the latin bos (= cow), refering to a pair of phallosomal processes that resemble cow horns.

Description: Male (available only by partly cleared and dissected specimen). Head. Coloration unavailable. Eye small, IO/D = 1.3.

Thorax. Coloration of prothorax unavailable. Mesonotum white in ground colour, each lobe of scutum with large brown marking, marking on anterior lobe divided bilaterally by narrow white line, marking on lateral lobe divided in two by narrow transverse white line; scutellum white, anterior margin brown; postnotum brown. Metanotum brown, median lobe with longitudinal white line medially; lateral lobe with white spot posteriorly; scutellum white; postnotum brown. Meso- and metapleurites brown except membranous region, postero-ventral corner of anepisternum and median part of epimeron white.

Legs. Missing.

Forewing ( Fig. 1F ). Spots in cell a 1 distinct only for distal small spot. Opposing spots in cell r distinct only for small, semicircular posterior spot. Proximal band represented by circular marking just below fork of M + Cu, narrow marking along basal section of Rs, and faint brown tinge in cell CuP. Distal band almost indistinct except for faint brown tinge in cell r 5. Spot on roof of cell m 3 broad and distinct. Submarginal spots distinct only for large spots in cells r 5, m 1 and m 2. Marginal clouds faint, only visible along distal ends of vein R 2+3, R 4+5 and M 1. Hindwing. Hyaline, cell CuP with faint brownish marking distally; veins brown.

Abdomen. Pregenital segments missing. Terminalia. Clunium, epiproct and paraproct missing. Hypandrium (left postero-lateral corner missing, possibly including left process: Fig. 3I ): group of setae at postero-lateral corner; left process unknown; right process reduced to tiny conical process projecting from near postero-lateral corner; median tongue short and broad, broadened basally, basal part with two pairs of processes laterally, distal pair smaller and conical, basal pair larger and covered by denticles, apical margin serrated and hollowed at middle, ventral surface covered by wrinkles and tiny denticles. Phallosome ( Fig. 3J ): pair of strongly hooked processes (= pseudoparameres?) arising from posterolateral corner, processes widely separated by aedeagus, this with small notch medially. Phallobase parallel sided, then gradually narrowing to opened anterior tip.

Length. B (unavailable); FW 2.1; HW 1.6.

Female. Unknown.

Distribution. Peru.
