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 : 81

Triplocania newi n.sp. (Male).

( Figures 15–21 )

Diagnosis. Close to T. calcarata New , from which it differs in having the mid posterior projection of the hypandrium much longer and blunt ended, in having the side projections of the hypandrium much smaller, and in having the posterior endophallic sclerites of the phallosome ending in three acuminate projections, and in having the mesal, acuminate process of each arm of the posterior pair of endophallic sclerites much larger.

Color. Body pale brown, with dark brown spots as indicated below. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 15 ). Thoracic pleura with small ochre spots above the level of the coxae. Scape and pedicel pale brown; flagellomeres pale yellow. Mx4 pale yellow with distal end pale brown. Legs yellow. Forewings hyaline, as illustrated ( Fig. 16 ), veins brown. Hindwing ( Fig. 17 ), hyaline with veins brown. Abdomen whitish, with dark brown, transverse subcuticular bands.

Morphology. Compound eyes with interommatidial setae. Outer cusp of lacinial tip broad, with four denticles ( Fig. 18 ). Forewing pterostigma long, narrow anteriorly, wider in the middle. Areola postica wide based, rounded. R 2+3 and R 4+5 sinuous, M stem concave, M 1 almost straight, M 2 sinuous, M 3 branched, with branches sinuous. Hindwing Rs almost straight, R 2+3 and R 4+5 almost straight, M stem concave proximally, then almost straight. Paraprocts broadly semi-elliptic, a field of setae along inner margin, other setae on apex; sensory fields with 27–28 trichobothria on basal rosettes ( Fig. 19 ). Epiproct wide based, posteriorly rounded, three setae on apex and three large mesal setae, next to anterior margin ( Fig. 19 ). Hypandrium of one sclerite, rounded anteriorly and distally triangular, with a long, slender, acuminate projection posteriorly, one projection on each antero-lateral extreme, deeply concave in outer margin, forming two acuminate projections, setae as illustrated ( Fig. 20 ). Phallosome ( Fig. 21 ) with broad, independent side struts, fused posteriorly to external parameres, these rounded distally, bearing an field of pores, each with an elongate projection distally, outwardly curved at the end; three pairs of endophallic sclerites, a posterior pair parallel to the inner margin of the external parameres, each arm broad, basally narrow with and acuminate projection mesally near inner border, ending in three acuminate extensions, the outer one short, and the outer two long, slender, curved outwards; a mesal pair, narrow at the ends, wide in the middle; and an anterior pair, V-shaped, behind the posterior and mesal sclerites.

Material examined. Holotype male ( INPA). Brazil. GO[iás][Tocantins]. Anaguacena. 26.I.1983. J.A. Rafael . Paratypes: 1 male. Brazil. AM [azonas]. Manaus. P. [arque] Laranjeiras. CDC trap. 15.I–20.II.1982. João e Nonato . 1 male ( INPA). Same data as paratype above, except 28. V –3.VII.1981. Light [Trap]. J. Arias .

Etymology. This species is gratefully dedicated to Dr. Timothy R. New (LaTrobe University, Bundoora, Victoria, Australia), in recognition to his important work on South American Psocoptera, particularly in Brazil; he described the first two species of Triplocania with forewing M3 forked ( T. calcarata and T. furcata , from the states of Amazonas and Mato Grosso, respectively).
