Poeciloderrhis tijucana sp. n. Figures 37-45

General coloration.

Shiny light brown (Fig. 37). Head with vertex, interocular space between ocelli brown; other regions light brown. Maxillary palps with apical segment brown, cilia golden. Eye brown (Fig. 38). Pronotum light brown, with dark brown punctations (Fig. 39); tegmen light brown, with dark brown punctations. Legs light brown with spine, pulvilli, arolia and claws dark brown. Abdomen light brown.

Dimensions (mm).

Total length: 33; total length of pronotum: 7.0; width of pronotum: 8.25; length of tegmen: 28; width of tegmen: 7.9.

Head.

Triangular with rounded edges, vertex slightly exposed; interocular space about 1.0 mm. Antennae long, slender, and tomentose, reaching beyond apex of cerci. Eyes positioned antero-laterally; maxillary palps with first and second segments reduced, the latter 0.46 mm, third segment 25% larger than fourth and 10% larger than fifth, which is a little more dilated and very tomentose.

Thorax.

Pronotum ample, pentagonal, convex, with curved margins, base bearing small median projection. Legs developed, femur I bearing 7 strong spines on anteroventral half, followed by series of small spines towards apex, where two strong apical spines are present; posteroventral surface with three strong spines, one apical; femora II and III with strong spaced spines on ventral surfaces. Pulvilli present on four tarsal segments, claws symmetrical and specialized, with two rows of small spines on ventral surface. Tegmen not reaching beyond apex of abdomen.

Abdomen.

Tergal modification with two latero-apical humps converging toward thorax on first segment and small median hump on second tergite (Fig. 40). Supra-anal plate round with cerci reaching over apex of plate and short apical cleft (Fig. 41). Subgenital plate asymmetrical with apical cleft, with one long, filiform style and another inconspicuous one (Fig. 42). Genitalia with left phallomere with median structure shaped as sclerotized cleft (Fig. 43); median sclerite round apically and sclerotized on pre-apical region, with prepucium membranous bearing small spines (Fig. 44, 45). Right phallomere with curved apex and a small apical spine (Fig. 46).

Material examined.

Holotype ♂, Brazil, Rio de Janeiro, Tijuca. No date and collector information.

Etymology.

This species is named after the type locality, Tijuca, in Rio de Janeiro.

Diagnosis.

This species is close to Poeciloderrhis ferruginea in size, differing in: the coloration of the tegmina being more intense in Poeciloderrhis ferruginea , ventral view, the subgenital plate having the right style small but distinct in Poeciloderrhis ferruginea , and in the median sclerite having a sharp apex in Poeciloderrhis ferruginea .
