Lachesilla longiproctus View in CoL n. sp.
( Figs. 19–21 View FIGURES 19 – 21 )
Diagnosis. Belonging in group pedicularia. Distal end of claspers free. Phallosome apodeme, long, slender, dilated posteriorly and divided in two slender arms, each directed laterally; a rounded, spiny area on each side, next to distal ends of claspers. Clunium extended posteriorly in area over epiproct. Paraprocts elongate, of two pieces, the proximal one articulated to clunium; the distal one with a mesal, slender prong ( Fig. 20 View FIGURES 19 – 21 ). Epiproct divided in two halves, each projected posteriorly to form a slender acuminate arm, the right one slightly shorter than the left one ( Fig. 20 View FIGURES 19 – 21 ).
Color. Body medium brown. Compound eyes black, ocelli hyaline, without centripetal crescents. Antennae, maxillary palps and legs pale brown. Wings hyaline, witha slight reddish hue. Veins brown. Abdomen creamy white, with dark brown subcuticular rings.
Morphology. As in diagnosis, plus the following: forewing pterostigma wider posteriorly, Rs-M veins joined by a crossvein or diverging from a point. Areola postica wide, apically rounded. Hindwing Rs-M veins fused for a distance. Hypandrium triangular, setose; claspers elongate, basally broad, with setae as illustrated, with a slender, sclerotized band along inner edge; distal end of each clasper slender, straight, truncate. Proximal half of paraproct with elliptic sensory field, bearing 11–12 trichobothria on basal rosettes, and a marginal one without basal rosette; distal half slender, setose. Epiproct with a setal field posteriorly on each half.

Etymology. The specific name refers to the length of the epiproct projections.
Remarks. L. longiproctus and L dividiproctus belong in an assemblage of species, within the group pedicularia, in which the male epiproct is projected posteriorly in two long apophyses, or is divided in two halves, each half extended into a long projection; this assemblage includes the following species: L. aldretei Badonnel ( Colombia) , L. assymetriproctus García Aldrete ( Peru) , L. convexicornis García Aldrete ( Peru) , L.
symmetriproctus García Aldrete ( Peru), L. trujillensis García Aldrete ( Venezuela) , and L. veneper García Aldrete ( Venezuela, Peru).
