González-Obando, Ranulfo, Carrejo-Gironza, Nancy & García, Alfonso N., 2021, New species of Triplocania Roesler (Psocodea: ‘ Psocoptera’: Ptiloneuridae) from Colombia and Peru, Zootaxa 5080 (1), pp. 1-63 : 24-26

Triplocania caquetensis n. sp. Male

( Figs 55–60 )

Diagnosis. It belongs in species group lucida , of Subgroup MPB2A (see Classification below). It is close to T. caguanensis n. sp. The central sclerite of the hypandrium follows the same structural plan in both species, but the median posterior processes are stouter, straight and distally rounded in T. caquetensis . The phallosomes are almost identical in both species, but the anterior endophallic sclerite, the lateral sclerites, and the mesal sclerite are larger in the former, also, the mesal denticles in the inner border of the external parameres are better developed in the latter.

Color (in 80% ethanol). Body brown to cream. Head pale brown, with dark brown spots pattern ( Fig. 57 ). Compound eyes dark brown, ocelli hyaline, with ochre centripetal crescents; antennae and maxillary palps pale brown. Thorax brown, tergal lobes of meso- and metathorax brown with cream spots. Pronotum and propleura cream, propleura with ochre spots. Thoracic mesopleura-metapleura brown, with small cream to ochre-brown spots. Legs pale brown; coxae with dark spots basally and distally, femora with small dark spots distally; tibiae and tarsi pale brown. Forewings almost hyaline, with pale brown spots at the ends of veins R, M, CuA 1, CuA 2 and intersection A1-CuP; pterostigma with brown bands proximally and distally; veins pale brown ( Fig. 55 ). Hindwings mostly hyaline, veins pale brown, with brown spots at distal ends of R and M veins ( Fig. 56 ). Abdomen cream with ochre spots. Epiproct and paraprocts light brown. Sclerites of hypandrium pale brown, lateral sclerites darker than central sclerite. Endophallic sclerites dark brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 57 ): H/MxW: 1.61; H/D: 2.18; IO/MxW: 0.61. Vertex slightly emarginate, at the level of the upper edge of the compound eyes. Outer cusp of lacinial tips broad, with four denticles. Mx4/Mx2: 1.42. Forewings ( Fig. 55 ): L/W: 2.47. Pterostigma: lp/wp: 4.48. Areola postica triangular: la/ha: 1.85, CuA 1 gently concave distally. Hindwings ( Fig. 56 ): l/p: 2.80. Hypandrium ( Fig. 59 ) of three sclerites. Phallosome ( Fig. 60 ), side struts slender, basally separated, Y-shaped, lateral sclerites straight, well sclerotized, club-shaped; external parameres broad, distally rounded, with pores, a sinuous, acuminate process anteriorly on each inner border, also, a small denticle mesally on each inner border. Median process of mesal endophallic sclerite with rounded apex, without distal denticles. Paraprocts oval, with abundant medium sized setae and macrosetae on distal third, at least one apically spatulate macroseta, a macroseta near each sensory field, these with 20 trichobothria on basal rosettes ( Fig. 58 ). Epiproct ( Fig. 58 ) wide, broadly rounded posteriorly, setae and macrosetae as illustrated.
