Triplocania mariaelinae  n. sp.

( Figures 87–102View FIGURES 87 – 94View FIGURES 95 – 102)

Diagnosis. Differing from the known species of Triplocania  by the uniquely shaped central sclerite of the hypandrium, strongly convex anteriorly and posteriorly, with a median, stout, setose posterior process. The phallosome is reminiscent to that of T. lucida Roesler  , differing from it in general structure, and in having only two pairs of endophallic sclerites.

Male. Color. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 87View FIGURES 87 – 94). Scape pale brown, pedicel yellow; f 1 –f 3 yellow, with apex white. Mx 4 pale yellow. Femora pale yellow; tibiae yellow; tarsomeres 1–3 pale yellow. Forewing mostly hyaline; pterostigma with a small brown spot distally, a small brown spot on confluence of CuP- 1 A, with a brown area limited by CuP proximally at wing margin; veins brown ( Fig. 88View FIGURES 87 – 94). Hindwing hyaline; veins brown ( Fig. 89View FIGURES 87 – 94).

Morphology. Head vertex straight; compound eyes without interommatidial setae. Outer cusp of lacinial tip broad, with four denticles ( Fig. 90View FIGURES 87 – 94). Forewing pterostigma wider in the middle, narrow basally; Rs stem slightly convex proximally, then almost straight, R 2 + 3 straight, R 4 + 5 sinuous, M stem slightly concave proximally, then almost straight, M 1 stem slightly convex proximally, then almost straight, M 2 and M 3 almost straight,; areola postica wide basally, slightly slanted posteriorly, 2 A not reaching wing margin. Hindwing Rs slightly convex, R 2 + 3 and R 4 + 5 almost straight, M sinuous. Hypandrium of three sclerites, a large central sclerite, anteriorly and posteriorly convex, with borders sclerotized; a short, blunt ended, median posterior setose process; side sclerites large, irregular in shape; setae as illustrated ( Fig. 91View FIGURES 87 – 94). Phallosome ( Fig. 92View FIGURES 87 – 94) with side struts independent, V shaped, fused posteriorly to external parameres, these with tip broad and with pores posteriorly; two pairs of endophallic sclerites, anterior pair of three arms, inner arms short, with pointed processes on outer border; outer arms long, stout, blunt ended, middle arms wide based, narrowing distally, acuminate. Posterior pair proximally rounded, long, slender, narrow in the middle and widening posteriorly, curved inwards, ending in four acuminate apophyses. Epiproct wide based, broadly triangular, with a small area heavily sclerotized in the middle, setae as illustrated ( Fig. 93View FIGURES 87 – 94). Paraprocts broad, almost square, sensory fields with 21 trichobothria on basal rosettes, setae as illustrated ( Fig. 94View FIGURES 87 – 94).

Measurements (in microns): FW: 2807, HW: 1920, F: 734, T: 1232, t 1: 513, t 2: 58, t 3: 114, f 1: 370, f 2: 190, Mx 4: 283, IO: 340, D: 323, d: 188, IO/d: 1.80, PO: 0.58.

Female. Color. Essentially as in the male.

Morphology. Head with vertex slightly concave, compound eyes without interommatidial setae ( Fig. 95View FIGURES 95 – 102). Fore- and hindwings ( Figs 96, 97View FIGURES 95 – 102) same as in the male. Outer cusp of lacinial tip broad, with four denticles ( Fig. 98View FIGURES 95 – 102). Subgenital plate broad, sides converging to a pointed apex; pigmented area with a deep, longitudinal cleft in the middle ( Fig. 99View FIGURES 95 – 102). Ninth sternum ( Fig. 100View FIGURES 95 – 102) broad, with anterior border strongly sclerotized, with a deep concavity in the middle; two almost elliptic areas, one large and one small, near posterior border, on each side of the longitudinal midline. Gonapophyses: v 1 long, slender, heavily sclerotized; v 2 + 3 stout, wide proximally, with short, blunt ended heel; five setae on outer lobe as illustrated, distal process slender, acuminate, with a field of microsetae ( Fig. 101View FIGURES 95 – 102). Epiproct triangular, sclerotized almost throughout, with three mesal setae, other setae as illustrated ( Fig. 102View FIGURES 95 – 102). Paraprocts broadly triangular, with a distinct area more sclerotized, sensory fields with 25 trichobothria on basal rosettes; setae as illustrated ( Fig. 102View FIGURES 95 – 102).

Measurements (in microns): FW: 3010, HW: 1993, F: 764, T: 1240, t 1: 534, t 2: 62, t 3: 133, f 1: 393, f 2: 201, Mx 4: 292, IO: 350, D: 338, d: 198, IO/d: 1.76, PO: 0.58.

Material examined. Holotype male ( INPA  ). Brazil. Pará, Altamira. Caverna Abrigo do Sismógrafo (03º 17 ’ 18 ”S: 52 º 13 ’ 28 ”W). 7.VII. 2009. Franco, F. Paratypes: 1 male and 1 female (LES/UFSCar). Same data as the holotype. 1 female ( INPA  ). Same data as the holotype.

Etymology. This species is dedicated to Dra Maria Elina Bichuette  , of the Universidade Federal de São Carlos, São Paulo, Brazil, for the loan of the specimens from Altamira here described, and in recognition to her enthusiasm and energetic psocid collecting in Brazilian caves.
