Triplocania lamasoides sp. n. Figures 15-21, 22-26


Brazil, Rondônia: Ariquemes, Rio ji Paraná, 90°44'S: 61°52'W, Malaise trap. 28.I.1986, J. A. Rafael leg.


Holotype male, mounted on slides, with thorax in a separate microvial. Original label: Brasil. Rondonte [ Rondônia]. Ariquemes, Rio ji Paraná. 28.I.1986. 90°44'S: 61°52'W. Malaise trap. J. A. Rafael. Paratypes: 1 female and 3 males, same data as the holotype (INPA, slides 57-61, vials 57-61).


The specific name refers to the proximity of this species to Triplocania lamasi Silva–Neto, Rafael & García Aldrete.


Differing from Triplocania lamasi in having the posterior sclerite of the hypandrium thicker in the middle, with the posterior projection more than twice as long; sickle-shaped lateral projections distal to the anterior sclerite barely reaching the inner margins of the lateral sclerites.


Color. Body yellowish brown, with dark brown spots as indicated below. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern (Fig. 15). 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 hyaline, as illustrated (Fig. 16); veins brown. Hindwing (Fig. 17), hyaline throughout, veins brown.


As in diagnosis, plus the following: compound eyes with interommatidial setae. Outer cusp of lacinial tip broad, with six denticles (Fig. 18). Forewing pterostigma long, widest in the middle. Areola postica wide basally, slightly slanted posteriorly, apex round, narrow. R2+3 and R4+5 sinuous, M stem concave, M1 almost straight, M2 sinuous, M3 branched, the branching point closer to M than to the wing margin. Hindwing Rs almost straight. Hypandrium (Fig. 19) of four sclerites, anterior piece broad, setose, bearing distally two sickle-shaped lateral projections, heavily sclerotized at both ends, and having also a well defined, setose sclerotized area in the middle; posterior sclerite concave anteriorly, with a long, slender posterior projection in the middle, flanked by two large, broadly triangular lateral sclerites. Phallosome (Fig. 20) 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; anterior pair long, slender and curved, mesal pair wide proximally, narrowing distally, pointed, and posterior pair parallel to the inner margin of the external parameres, with three acuminate projections distally. Paraprocts broad, wide proximally, narrowing to round apex; with a field of short setae along inner margin, other setae as illustrated; sensory fields with 30-31 trichobothria on basal rosettes (Fig. 21). Epiproct mesally with an almost elliptic protuberance, with a field of setae posteriorly, and three large mesal setae next to anterior margin (Fig. 21).

Color. Essentially as in the male.


Fore- and hind- wings (Figs 22, 23) same as in the male. Subgenital plate broad, V shaped, pigmented area wide, setae as illustrated (Fig. 24); Gonapophyses: V1 long, slender, heavily sclerotized; V2+3 stout, heeled, narrow anteriorly and wider in the middle, with three large setae on outer lobe as illustrated, distal process stout, sinuous, distally blunt, with a field of microsetae (Fig. 25). Ninth sternum broad, with two distinct areas, the anterior one unpigmented, with a concavity anteriorly and posteriorly in the middle; posterior area pigmented, thicker than the anterior one, with a strongly sclerotized band latero-posteriorly, and a small, strongly pigmented area mesally on each side. Paraprocts broad, almost triangular, wide proximally, narrowing to round apex, setose posteriorly as illustrated, sensory fields with 26-27 trichobothria on basal rosettes (Fig. 26). Epiproct missing.
