Lachesilla huitoto  n. sp.

( Figures 7 − 22View FIGURES 7 − 12View FIGURES 13 − 19View FIGURES 20 − 22)

Diagnosis. Belonging in species group pedicularia ( García Aldrete, 1974)  . Males differing from L. ilama  in having the clunial apophysis longer; in having the epiproctal apophyses stouter, with a short, broad spine on the inner margin of the basal half. Differing from L. carpinteroi  , in addition to the epiproct spine character, in having the epiproctal apophyses almost straight, curved distally; in having the clunial apophysis broader and in having the process resulting from the fusion of the distal ends of the claspers apically bifurcated. The females differ from L. asymmetriproctus  in having the subgenital plate broad, with a pigmented area on each side of the longitudinal midline and in having the ninth sternum with a narrow transverse band. Differing from L. convexicornis  in having the subgenital plate not extended posteriorly, with each lobe bearing setae only distally. Differing from L. macropudenda  in having long and slender gonapophyses; in having a pigmented area on each side of the longitudinal midline of the subgenital plate, without a dark brown inner area. Differing from L. cesarcardonai  in having the subgenital plate posteriorly bilobed; in having the gonapophyses straight; in having the ninth sternum with the spermapore near the border of the narrow transverse band.

Description. Male. Color (in 80 % ethanol). Head brown, frontal suture dark brown, compound eyes black, ocelli hyaline, with dark brown centripetal crescents. Thorax and coxae brown. Abdomen creamy with subcuticular rings light brown. Clunium and clunial apophysis dark brown. Paraprocts brown, epiproct light brown. Forewing membranes brownish, opaque; pterostigma darker distallly. Hindwings opaque, veins brown.

Morphology. Vertex of head slightly concave ( Fig. 9View FIGURES 7 − 12). Tergal mesothoracic lobes prominent; precoxal bridge broad; membranous region of metapleura broad. Forewing length-width relation 2.3; pterostigma wider distally, length-width relation 2.5, Rs-M veins meeting at a point ( Fig. 20View FIGURES 20 − 22) or joined for a short length ( Fig. 7View FIGURES 7 − 12). Hindwing length-width relation 2.8; Rs-M veins fused for a length ( Fig. 8View FIGURES 7 − 12). Hypandrium membranous, laterally joined to claspers. Claspers well sclerotized, wider proximally, rounded, with distal ends fused to form a broadly bifurcated projection, with long setae and with two apically membranous areas with papillose surface ( Fig. 12View FIGURES 7 − 12). Phallosome apodeme long, slender, “T” shaped ( Fig. 12View FIGURES 7 − 12). Clunium with a broad apophysis, widened distally and projected over the epiproct, with posterior border straight ( Fig. 10View FIGURES 7 − 12) or slightly concave ( Fig. 22View FIGURES 20 − 22). Paraprocts of two well sclerotized pieces; a basal one with 13 trichobothria (one without basal rosette) on the sensory fields, the distal one with a short hook-like prong, truncated and with a small seta in apex ( Fig. 10View FIGURES 7 − 12). Epiproct broad, bilobed, connected in the middle by a membranous, setose bridge; each lobe with a long, almost straight and apically curved apophysis, projected beyond the base of the clunial apophysis in lateral view ( Fig. 11View FIGURES 7 − 12) and with a short, broad spine on the inner margin of the basal half ( Figs 10View FIGURES 7 − 12, 22View FIGURES 20 − 22).

Epiproct brown with a pale central area. Paraprocts light brown, with inner margin slightly darker. Head with frontal suture brown; ocelli with brown centripetal crescents. Thorax and abdomen as in males.

Morphology. Vertex of head slightly concave ( Fig. 15View FIGURES 13 − 19). Tergal mesothoracic lobes prominent; precoxal bridge broad; membranous region of metapleura broad. Forewing length-width relation 2.4; pterostigma wider distally, length-width relation 2.8; Rs-M veins meeting at a point ( Fig. 21View FIGURES 20 − 22) or joined for a short length ( Fig. 13View FIGURES 13 − 19). Hindwing length-width relation 2.9; Rs-M veins fused for a length ( Fig. 14View FIGURES 13 − 19). Subgenital plate broad, apically bilobed, each lobe with setae distally ( Fig. 17View FIGURES 13 − 19). Gonapophyses long, slender with setae towards the outer margin; with a basal area slightly pigmented ( Fig. 18View FIGURES 13 − 19). Ninth sternum membranous, with two rounded, well sclerotized areas and with a narrow transverse band distally; spermapore round ( Fig. 18View FIGURES 13 − 19). Paraprocts almost rectangular, sensory fields with 10 trichobothria (one without basal rosette, Fig. 16View FIGURES 13 − 19).
