Triplocania lamasi n.sp. (Male)

( Figures 1–7 )

Diagnosis. Differing from the known species of Triplocania , in having the hypandrium of four pieces, and in having a distinct, elliptic protuberance mesally on the epiproct.

Color. Body yellowish brown, with dark brown spots as indicated below. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 1 ). Scape and pedicel pale brown; flagellomeres pale yellow. Mx4 pale yellow. Tergal lobes of meso- and metathorax reddish brown; episternum of mesothorax ochre. Coxae, trochanters and femora creamy white, tibiae and tarsomeres pale yellow. Forewings almost hyaline, as illustrated ( Fig. 2 ); a brown spot on confluence of Cu 2 –1A; veins brown. Hindwing ( Fig. 3 ), almost hyaline throughout, veins brown.

Morphology. Compound eyes with interommatidial setae. Outer cusp of lacinial tip broad, with six denticles ( Fig. 4 ). Forewing pterostigma long, widest in the middle. Areola postica wide basally, slanted posteriorly, apex round, narrow. R 2+3 and R 4+5 sinuous, M stem concave, M 1 almost straight, M 2 sinuous, M 3 branched, with sinuous branches. Hindwing Rs almost straight, R 2+3 sinuous, R 4+5 almost straight. Paraprocts broad, wide proximally, narrowing to round apex; with a field of short setae along inner margin, other setae as illustrated; sensory fields with 32–34 trichobothria on basal rosettes ( Fig. 5 ). Epiproct mesally with an almost elliptic protuberance, with setae along sides and posterior margin, and three large mesal setae ( Fig. 5 ), next to anterior margin. Hypandrium ( Fig. 6 ) of four sclerites, broader anterior piece, anteriorly rounded; two long sickle-shaped lateral projections posteriorly, heavily sclerotized proximally and distally, a well-defined, setose sclerotized area in the middle; one posterior sclerite, anteriorly concave, with a stout, mid posterior projection, flanked by two large, rounded sclerites. Phallosome ( Fig. 7 ) with side struts independent, V shaped, fused posteriorly to external parameres, these stout, each with an elongate projection on inner margin, with field of pores; three pairs of endophallic sclerites, a posterior pair parallel to the inner margin of the external parameres, with three acuminate projections distally; a mesal pair, narrow, elongate and curved, with ends almost together in the middle of endophallus, and an anterior pair, with each arm branched posteriorly and membranous, fused with the other arm.

Measurements (in microns): FW: 3716, HW: 2554, F: 934, T: 1563, t1: 667, t2: 53, t3: 112, f1: 536, f2: 400, f3: 280, Mx4: 270, IO: 339, D: 393, d: 303, PO: 0.77.
