González-Obando, Ranulfo, Carrejo-Gironza, Nancy & García, Alfonso N., 2017, New species of Colombian Triplocania Roesler (Psocodea: ‘ Psocoptera’: Ptiloneuridae), Zootaxa 4336 (1), pp. 1-113 : 51

Triplocania guane n. sp. Female

( Figs 158–163 )

Diagnosis. Similar to T. matildae n. sp., from which it differs by having the pigmented marginal band of the forewings narrower, by having the areola postica much wider ( Fig. 158 ), and by having the ninth sternum more slender posteriorly, with the anterior, transverse pigmented band narrower ( Fig. 162 ); also 2A ends in the wing membrane, not reaching the wing margin, and the head pattern is different ( Fig. 160 ).

Color (in 80% ethanol). Body pale brown, with dark and light spots. Compound eyes dark brown; ocelli hyaline, with ochre centripetal crescents. Head brown, with pale brown spots on vertex, front and clypeus ( Fig. 160 ). Central area of postclypeus with dark brown V-shaped area; genae with extensive brown area. Tergal lobes of meso- and metathorax pale brown, mottled cream. Pleura creamy. Fore- and hind- coxae cream, mid coxae pale brown. Forewings hyaline, with a pale brown marginal band from R2+3 to 1A; pterostigma hyaline with pale brown spots. Hindwings hyaline. Abdomen pale cream, with subcuticular pale brown spots. Subgenital plate hyaline in the middle, with pigmented area dark brown. Gonapophyses brown. IX sternum pale brown with transverse, anterior pigmented area. Epiproct and paraprocts pale brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 160 ): H/MxW: 1.45; compound eyes: H/D: 3.10; IO/MxW: 0.75, MxW/IO: 1.93. Vertex slightly above the level of the compound eyes. Outer cusp of lacinial tips broad, with seven denticles. Forewings ( Fig. 158 ): L/W: 2.54. Pterostigma elongate, almost six times as long as wide: lp/wp: 5.77; areola postica: la/ha: 2.05. Hindwings ( Fig. 159 ). Subgenital plate wide, semioval, with dense field of setae. Gonapophyses ( Fig. 162 ): v1 elongate, slender, acuminate; v2 +3 proximally with a short pointed heel, v2 with a row of eight macrosetae; distal process long, acuminate, with abundant microsetae. IX sternum ( Fig. 162 ). Paraprocts ( Fig. 163 ), broadly triangular, with a field of setae posteriorly, as illustrated; sensory fields with 34 trichobothria on basal rosettes. Epiproct ( Fig. 163 ) triangular, wide based, rounded posteriorly, setae as illustrated.

Measurements. FW: 7750; IO: 700; D: 437; d: 312; IO/d: 2.24; PO: 0.71.
