Neto, Alberto Moreira Da Silva, Rafael, José Albertino & García Aldrete, Alfonso N., 2014, New species of Triplocania Roesler with forewing M 3 forked (Psocodea: ’ Psocoptera’: Ptiloneuridae), from Brazil, Zootaxa 3838 (1), pp. 77-86 : 79-81

Triplocania mariateresae n.sp. (Male)

( Figures 8–14 )

Diagnosis. Close to T. plaumanni n.sp., described below; differing from it in having a wider concavity between the posterior projections of the central piece of the hypandrium, in having the side struts of the phallosome not fused to the external parameres, in having the posterior pair of endophallic sclerites distally acuminate, and by the much larger overall size.

Color (in 80% ethanol). Body creamy, with dark brown spots as indicated below. Tergal lobes of meso- and metathorax dark brown; thoracic pleura with irregular brown spots above the level of the coxae. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 8 ). Scape and pedicel pale yellow, f 1 pale yellow with a brown area subapically, apex white, f 2 - f 6 brown, with distal ends white. Mx4 yellow. Legs pale brown. Abdomen whitish, with ochre, transverse subcuticular bands. Forewings almost hyaline, as illustrated ( Fig. 9 ), veins brown; pterostigma with brown spots proximally and distally, brown spots distally on veins R 2+3 to Cu 1b, at wing margin. Hindwing ( Fig. 10 ) almost hyaline throughout, veins brown.

Morphology. Compound eyes without interommatidial setae. Outer cusp of lacinial tip broad, with six denticles ( Fig. 11 ). Forewing pterostigma elongate, constricted proximally. Areola postica tall, apex round, slightly slanted posteriorly. R 2+3 and R 4+5 sinuous, M stem slightly concave proximally, then almost straight, M 1 almost straight, M 2 sinuous, M 3 branched, with branches sinuous. Hindwing Rs, R 2+3 and R 4+5 almost straight. Paraprocts ( Fig. 12 ) triangular, with setae as illustrated, sensory fields with 30–31 trichobothria on small basal rosettes. Epiproct ( Fig. 12 ) wide basally, with sides converging to round apex, with setae as illustrated. Hypandrium ( Fig. 13 ) of three sclerites, a large central one, with a stout, wide based, distally blunt posterior projection on each side, leaving a wide concavity between them; each projection with sides almost parallel on basal two-thirds, distal third narrow; setae as illustrated; flanked by two smaller, setose, almost triangular sclerites. Phallosome ( Fig. 14 ) with side struts independent, V shaped, joining distally the external parameres, these stout, each with a field of pores mesally on outer margin; three pairs of endophallic sclerites, a posterior pair parallel to the inner margin of the external parameres, distally shaped like a bird head; a mesal pair, broad basally, deeply concave in the inner margin, narrowing posteriorly; and an anterior pair, broad basally, narrowing distally and curving behind the distal ends of the side struts.

Measurements (in microns): FW: 6475, HW: 4185, F: 1176, T: 1672, t1: 787, t2: 98, t3: 153, f1: 1313, f2: 1343, f3: 1225, Mx4: 324, IO: 473, D: 463, d: 311, PO: 0.67.

Material examined. Holotype male ( INPA). Brazil. Rio de Janeiro. Itatiaia National Park . 200 Km E Rio de Janeiro. Ca. waterfall, on rock wall with lichens. 7.IX.2003. A. N. García Aldrete.

Etymology. This species is dedicated to María Teresa Miaja, wife of A. N. García Aldrete, who, while in Rio de Janeiro, insisted on going to Itatiaia, to look for Ptiloneuropsis immaculata Roesler , a search that proved successful, resulting in the creation of the neotype of that species.
