Troctopsocoides erwini View in CoL n.sp. (female)

Color (in 80% ethanol, ca. 12 years). Body pale brown. Compound eyes reddish, ocelli hyaline. Legs brown, with distal ends of femora white, proximal and distal ends of tibiae and of each t1 white, t2’s pale brown, t3’s brown. Forewing ( Fig. 1 View FIGURES 1–8 ) with many small, brown spots. Hindwings ( Fig. 2 View FIGURES 1–8 ) slightly shaded.

Structural characters. Sculpture of integument in vertex and frons ( Fig. 5 View FIGURES 1–8 ) a polygonal net formed by irregular pentagons and hexagons with granulate surfaces. Lacinial tip ( Fig. 3 View FIGURES 1–8 ) with inner cusp pointed and outer cusp with a subapical, rounded protuberance. Maxillary palpus ( Fig. 4 View FIGURES 1–8 of segments 2-4): P2 straight, somewhat thickened, P4 bullet-shaped. Pretarsal claws ( Fig. 6 View FIGURES 1–8 ) each with a large preapical denticle and a minute more basal denticle. Forewing ( Fig. 1 View FIGURES 1–8 ) broad in middle, tapering beyond a line from distal end of pterostigma to distal end of areola postica to form a slenderer apical region. Rs-M junction in forewing a short crossvein; other aspects of wing venation typical of the family or as described in the generic diagnosis. Subgenital plate ( Fig. 7 View FIGURES 1–8 ) triangular, rounded apically, with a partial division (segmental?) near base; apex with four stout setae; other marginal setae shorter (non-marginal setae not shown); in middle, two curved lines running lengthwise, basal to T-shaped sclerite and a smaller crescent-shaped line on each side of the long lines; T-shaped sclerite stout with short arms; surface of plate basal to dashed line in Fig. 7 View FIGURES 1–8 , sculptured with a net of slender, transverse imbrications becoming compressed to longitudinal lines, as illustrated, near base. Ovipositor valvulae ( Fig. 8 View FIGURES 1–8 ): v1 large, reaching nearly to tip of v2+3; v2 fused with v 3 in basal two-thirds; v3 shallowly bilobed apically. Paraprocts ( Fig. 9 View FIGURES 9–13 ): semicircular, sensory fields each with four trichobothria and four setae with faintly developed basal rosettes. Epiproct ( Fig. 9 View FIGURES 9–13 ): triangular, with two macrosetae near apex; setae of paraprocts and epiproct as illustrated.
