Prolachesilla boliviana n. sp. Male

( Figs 1–5 )

Diagnosis. Hypandrium biconcave posteriorly ( Fig. 5 ). Aedeagal arch with sides parallel, terminating in a wide hood, posteriorly concave ( Fig. 4 ). Endophallus with a mesal, elongate body of small denticles. External parameres slender, with apical spines ( Fig. 4 ), each paramere associated anteriorly to a long, sclerotized rod, directed diagonally outwards. Posterior border of clunium projected over the area of the epiproct and paraprocts. Projection of clunium over the epiproct with wrinkled surface, widely concave distally, with slender postero-lateral corners; sides and posterior border sclerotized. Projection over each paraproct triangular, with border sclerotized ( Fig. 3 ).

Color. Body tawny brown, compound eyes black, legs pale yellow, forewings pale yellow, veins pale brown ( Fig. 1 ), hindwings yellowish, almost transparent. Tergal lobes of meso- and metathorax pale brown, abdomen creamy, with pale brown, subcuticular transverse bands. Clunial projections pale brown; epiproct and paraprocts creamy. Hypandrium pale brown.

Morphology. As in diagnosis, plus the following: head vertex almost straight, upper border of compound eyes slightly above the level of the vertex ( Fig. 2 ). Compound eyes with interommatidial setae. Forewing ( Fig. 1 ); L/W: 2.52; pterostigma elongate, wider distally, without setae on the membrane; lp/wp: 2.91. Areola postica triangular ( Fig. 1 ). Hindwing L/W: 2.91 ( Fig. 1 ). Paraprocts broad, elongate, rounded posteriorly; sensory fields with 18–20 trichobothria on basal rosettes ( Fig. 3 ). Epiproct ( Fig. 3 ) with sides parallel, posteriorly rounded, setae as illustrated.
