Vinasco-Mondragón, Andrés Felipe, González-Obando, Ranulfo & García-Aldrete, Alfonso N., 2018, The species group Amabilis of the genus Euplocania Enderlein (Psocodea: Psocomorpha: Ptiloneuridae), Zootaxa 4444 (1), pp. 43-65 : 55-58

Euplocania metensis n. sp. Male

Figs 43–48

Diagnosis. It is close to E. manausensis n. sp., differing from it by the narrow mesal endophallic sclerite, 0.4 times as wide as long; its short postero-median projection, by the spinose process in the posterior concavity of the central sclerite of the hypandrium and by the postero-lateral processes of the central sclerite of the hypandrium, anteriorly globular in E. metensis n. sp., and almost straight in E. manausensis n. sp.

Color (in 80% ethanol). Body creamy, with pale brown areas, as indicated below. Head ochraceous, with dark brown pattern as illustrated ( Fig. 45 ). Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Tergal lobes of meso- and metathorax ochraceous. Thoracic pleura with black stripes and spots. Legs: hind- and midcoxae creamy, with proximal dark brown stripe; fore coxae pale brown, with proximal dark brown stripe. Femora, tibiae and tarsi creamy. Forewings: veins brown, with a dark brown spot at wing margin; first section of vein Rs, crossvein Rs-M and vein M dark brown. Pterostigma dark brown, with a hyaline round window at the lower angle and a clear area in the proximal third ( Fig.43 ). Hindwings hyaline, veins pale brown, with a dark spot distally, except A2 ( Fig 44 ). Abdomen creamy, with subcuticular dark spots. Hypandrium brown, with median dark brown Y-like area. Epiproct pale brown, paraprocts with dark brown band limiting outer border of sensory fields.

Morphology. As in diagnosis, plus the following: Head ( Fig. 45 ): H/MxW: 1.53, H/d: 3.4, H/D: 2.07; compound eyes large: IO/MxW: 0.46. Vertex emarginate in the middle. Outer cusp of lacinial tip broad, with six denticles. Forewings ( Fig. 43 ): L/W: 2.91, pterostigma angulate and projected towards Rs: lp/wp: 4.67. Areola postica tall, slanted posteriorly, apex rounded, al/ah: 2.2. Hindwings ( Fig. 44 ): l/w: 2.81. Hypandrium convex posteriorly, lateral sides almost parallel, posterior processes flanking a short median arch that has numerous protuberances such as thorns ( Fig. 48 ). Phallosome anteriorly V-shaped ( Fig. 47 ), external parameres membranous, distally dilated, internally sclerotized and projected posteriorly. Lateral endophallic sclerites strong, wide anteriorly, narrowing posteriorly. Mesal endophallic sclerite transverse, posteriorly sinuous and slightly curved upwards, with a slender postero-median projection. Paraprocts ( Fig. 46 ) oval, almost triangular, basally wider, setose as illustrated, sensory fields with 31 trichobothria on basal rosettes. Epiproct wide, triangular, anteriorly rounded, convex posteriorly, with four macrosetae, two preapical and two median, posterior border with three setae and a row microspines as illustrated ( Fig. 46 ).

Measurements. FW: 4650, HW: 3300, f1: 940, IO: 560, D: 510, d: 360, IO/d: 1.56, PO: 0.71.
