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 : 84

Triplocania plaumanni n.sp. (Male).

( Figures 22–28 )

Diagnosis. Close to T. mariateresae n.sp., described above. For differences between the two species see diagnosis of the later, above.

Color. Body pale brown, with dark brown spots as indicated below. Tergal lobes of meso- and metathorax slightly more pigmented than rest of the thorax. Epimeron and episternum of mesothorax ochre. Pleura of metathorax with small, irregular ochre spots. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 22 ). Scape yellow, pedicel pale yellow, f 1 pale yellow with apex white and a brown band next to it, other flagellomeres brown with apex white. Mx4 light brown distally. Legs yellow. Abdomen whitish, with ochre, transverse subcuticular bands. Forewings almost hyaline, as illustrated ( Fig. 23 ), veins brown; pterostigma with brown spots proximally and distally, a brown spot on confluence of Cu 2 -1A, brown spots distally on veins R 2+3 to Cu 1b, at wing margin. Hindwing ( Fig. 24 ) almost hyaline throughout, veins brown.

Morphology. Compound eyes without interommatidial setae. Outer cusp of lacinial tip broad, with seven denticles ( Fig. 25 ). Forewing pterostigma long, basally narrow, wide posteriorly. Areola postica tall, with round apex. R 2+3 almost straight proximally and concave distally, R 4+5 sinuous. M stem slightly concave proximally, then almost straight, M 1 stem convex proximally, then almost straight, M 2 sinuous, M 3 branched, M 3a convex, M 3b short and almost straight. Hindwing Rs almost straight, R 2+3 short and straight, R 4+5 sinuous, M sinuous. Paraprocts broadly semi-elliptic, sensory fields with 29–30 trichobothria on basal rosettes, setae as illustrated ( Fig. 26 ). Epiproct almost semi-circular, three mesal setae near anterior border, other setae as illustrated ( Fig. 26 ). Hypandrium ( Fig. 27 ) of three pieces, a large central one, wide based, convex anteriorly, with two stout posterior projections, setose as illustrated, flanked by two smaller, elongate sclerites, with setae on posterior margin as illustrated. Phallosome ( Fig. 28 ) with side struts independent, elongate, wider anteriorly, then narrowing to join the external parameres, these wide distally, with a field of pores as illustrated. Three pairs of endophallic sclerites, an anterior pair curved, distally acuminate, proximally wide, the two arms almost touching in the middle; a mesal Ushaped sclerite, each arm associated distally with the posterior pair, each arm of this stout, slightly curved outwards distally, close to the ends of the external parameres.

Measurements (in microns): FW: 4154, HW: 2705, F: 933, T: 1569, t1: 619, t2: 81, t3: 110, f1: 687, f2: 664, f3: 529, Mx4: 212, IO: 423, D: 281, d: 205, PO: 0.729.

Material examined. Holotype male ( INPA): Brazil. Santa Catarina. Nova Teutonia. II. 1971. F. Plaumann.

Etymology. This species is dedicated, with great pleasure, to the late Dr. Fritz Plaumann, a great collector of Psocoptera.
