Lachesilla putumayensis  n. sp.

( Figures 1 − 6View FIGURES 1 − 6)

Diagnosis. Belonging in species group pedicularia ( García Aldrete, 1974)  ; clunium apophysis slender, widened distally, with apical margin straight, shorter than in L. cesarcardonai  , L. carpinteroi  and L. asymmetriproctus  , more slender than in L. ilama  ; differing from the Peruvian and Colombian species by having forceps-like epiproctal apophyses, not extended beyond the base of the clunial apophysis.

Description. Male. Color (in 80 % ethanol); head light brown, frontal suture dark brown, compound eyes black, ocelli hyaline, with small, brown centripetal crescents. Thorax and coxae brown. Abdomen creamy yellow with subcuticular rings light brown. Paraprocts brown, epiproct yellow. Forewing membrane brownish, opaque; pterostigma slightly darker; hindwings opaque, veins brown.

Morphology. Vertex of head slightly concave ( Fig. 3View FIGURES 1 − 6). Tergal mesothoracic lobes prominent; precoxal bridge broad; membranous region of metapleura broad. Forewing length-width relation 2.4; pterostigma wider distally, length-width relation 2.5; Rs-M veins fused by a short length; areola postica subtriangular, apically rounded ( Fig. 1View FIGURES 1 − 6). Hindwing length-width relation 2.8; Rs-M veins fused for a length ( Fig. 2View FIGURES 1 − 6). Hypandrium membranous, laterally joined to claspers. Claspers well sclerotized, wider proximally, distal ends fused to form a slightly bifurcated projection; with long setae and with two rounded membranous areas in apex ( Fig. 6View FIGURES 1 − 6). Phallosome apodeme long, slender, “T” shaped ( Fig. 6View FIGURES 1 − 6). Clunium with a slender apophysis, widened distally and projected over the epiproct ( Fig. 4View FIGURES 1 − 6). Paraprocts of two well sclerotized pieces; a basal one with 11 − 12 trichobothria (one without basal rosette) on the sensory fields, the distal one with a short hook-like prong, truncated at apex ( Fig. 4View FIGURES 1 − 6). Epiproct broad, bilobed, each lobe connected in the middle by a membranous, setose bridge; each lobe with a forceps-like apophysis, not projected beyond the base of the clunial apophysis in lateral view ( Fig. 5View FIGURES 1 − 6).
