Lachesilla huitoto View in CoL n. sp.

( Figures 7 − 22 View FIGURES 7 − 12 View FIGURES 13 − 19 View 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. 9 View 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. 20 View FIGURES 20 − 22 ) or joined for a short length ( Fig. 7 View FIGURES 7 − 12 ). Hindwing length-width relation 2.8; Rs-M veins fused for a length ( Fig. 8 View 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. 12 View FIGURES 7 − 12 ). Phallosome apodeme long, slender, “T” shaped ( Fig. 12 View FIGURES 7 − 12 ). Clunium with a broad apophysis, widened distally and projected over the epiproct, with posterior border straight ( Fig. 10 View FIGURES 7 − 12 ) or slightly concave ( Fig. 22 View 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. 10 View 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. 11 View FIGURES 7 − 12 ) and with a short, broad spine on the inner margin of the basal half ( Figs 10 View FIGURES 7 − 12 , 22 View FIGURES 20 − 22 ).

Female. Color. (in 80% ethanol). Subgenital plate with a pigmented area on each side, as illustrated ( Fig. 17 View FIGURES 13 − 19 ). Forewing membranes brownish, opaque, with a dark shadow along the membrane surrounding the basal half and pterostigma. Gonapophyses brown; ninth sternum opaque, with a brown transverse band. 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. 15 View 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. 21 View FIGURES 20 − 22 ) or joined for a short length ( Fig. 13 View FIGURES 13 − 19 ). Hindwing length-width relation 2.9; Rs-M veins fused for a length ( Fig. 14 View FIGURES 13 − 19 ). Subgenital plate broad, apically bilobed, each lobe with setae distally ( Fig. 17 View FIGURES 13 − 19 ). Gonapophyses long, slender with setae towards the outer margin; with a basal area slightly pigmented ( Fig. 18 View FIGURES 13 − 19 ). Ninth sternum membranous, with two rounded, well sclerotized areas and with a narrow transverse band distally; spermapore round ( Fig. 18 View FIGURES 13 − 19 ). Paraprocts almost rectangular, sensory fields with 10 trichobothria (one without basal rosette, Fig. 16 View FIGURES 13 − 19 ). Epiproct rounded posteriorly, slightly concave anteriorly, with setal field on distal half, as illustrated ( Fig. 19 View FIGURES 13 − 19 ).
