Steleops albertonetoi n. sp. (Male)

( Figs. 3−7 )

Color (in 80% alcohol). Body creamy white, with dark brown areas as indicated below. Compound eyes black, ocelli hyaline, with ochre centripetal crescents, thicker in the two upper ones. Head pattern as illustrated ( Fig. 4 ): two ochre bands from each compound eye, directed towards epistomal sulcus, meeting a slender ochre band radiating on each side of ocellar group, then continuing to epistomal sulcus; a creamy area between the bands from the compound eyes, and a large unpigmented area between ocellar group and epistomal sulcus, as illustrated. Postclypeus with ochre diagonal striae. Antennae: Scape pale brown, pedicel and flagellum creamy white; maxillary palpomeres 1−3 white, Mx4 pale brown. Prothoracic coxae pale brown; meso- and metathoracic coxae dark brown. Tergal lobes of meso- and metathorax dark brown. Abdomen creamy, with well defined brown bands on tergum, corresponding to each segment, these bands interrupted in the pleura of each side of the abdomen, to continue ventrally, but much less pigmented. Fore wings almost hyaline, veins brown, with brown spots on the basal part of the wing, as illustrated ( Fig. 3 ): small spot on cell R, small spot at confluence of Cu-Cu1a, a bigger spot between Cu2- A, toward distal ends, and a brown basal band between A and wing margin. Hind wings hyaline, veins pale brown.

Morphology. Head concave at vertex, compound eyes pedunculate ( Fig. 4 ), C: 210 microns; almost as long (from vertex to distal end of labrum) as wide at the level of the lower ends of the compound eyes. H/MxW: 1.09; almost triangular in front view, MxW/MnW: 1.52; compound eyes elongate. Fore wing pterostigma much wider posteriorly, lp/wp: 3.0; Rs-M joined by a short crossvein; Rs slightly curved and shorter than R 2+3; cell M almost rectangular; areola postica trapeziform. Hind wing Rs-M fused, Rs slightly longer than the fused length; vein R 4+5 1.7 times as long as Rs ( Fig. 3 ). Hypandrium symmetric ( Fig. 5 ) with sides basally straight; distal half of each side slender, strongly sclerotized, acuminate. Central body formed by two close together bean-shaped bodies, with two longitudinal, basal, acuminate projections; middle strap bearing a short acuminate prong basally on each side, and a field of short spines covering the whole surface. Phallosome ( Fig. 7 ) rhomboid, apex with a wide based, conical projection on one side, the other side associated with a long, rounded lobe, bearing a distal field of microspines. Clunium distinctly extended posteriorly over the area of the paraprocts-epiproct. Paraprocts ( Fig. 6 ) round, setose, sensory fields with 26−28 trichobothria in basal rosettes; mesal prong long, slender, curved at the end. Epiproct ( Fig. 6 ) approximately triangular, broad at base, extended posteriorly to form a long, distally rounded projection.

Measurements. FW: 2950, HW: 2180, f1: 630, f2: 540, f3: 510, IO: 470, D: 250, d: 280, IO/d: 1.68.

Specimen studied: Holotype male. BRAZIL. Bahia. Senhor de Bonfim, 10°22’197’’S: 40°10’840’’W, 800m. 8.x.2005. Light trap. R. Vieira & C. Chagas. MZUEFS, slide cod. 41464 (223).

Etymology. This species is dedicated to Alberto Moreira da Silva Neto, of the Universidade Estadual de Feira de Santana, Bahia, Brazil, for the loan of the specimen of this species, and in recognition to his enthusiasm and energetic psocid collecting in NE Brazil, within the frame of the Programa de Pesquisas em Biodiversidade (PPBIO −Semiárido).
