González-Obando, Ranulfo & Carrejo-Gironza, Nancy, 2023, Euplocania (Psocodea: Ptiloneuridae) in Peru, description of six new species, Zootaxa 5256 (2), pp. 173-187 : 184-185

Euplocania wchipere n. sp.

( Figs 35–40 )

Diagnosis. Forewing with a pale brown to brown wide band along margin, from R4+5 to cup cell. Ninth sternum trianguliform, with anterior margin convex, apical angle rounded. Due to the lack of knowledge of the males of this species, it is impossible to assign it to a group of species, since these have been proposed mainly based on characteristics of the hypandrium and phallosome.

Female. Color (in 80% ethanol). Head pattern ( Fig. 37 ). Compound eyes dark brown to black, ocelli hyaline, with ochre centripetal crescents. Vertex pale brown, with brown spots centrally. Frons pale brown, with dark brown transverse band between the inner margins of the compound eyes and between them and epistomal suture; postclypeus, anteclypeus, genae and labrum dark brown to brown. Antennae pale brown, scape brown, flagellomeres with apices cream. Maxillary palp brown, Mx1 clearer. Tergal lobes of meso- and metathorax brown, with pale brown spots. Thoracic pleura creamy, with brown spots. Legs: coxae dark brown, trochanters light brown with pale brown spot basally, mid- and hind- femora dark brown, cream apically, fore femur dark brown proximally, light brown distally, with preapical pale brown spot, tibiae and tarsi pale brown. Forewings almost hyaline, with a pale brown to brown wide band along margin, from R4+5 to cup cell; veins brown, with brown areolae on veins in setal insertions and a dark brown spot at end and at wing margin. Pterostigma hyaline basally dark brown proximally and apically ( Fig. 35 ). Hindwings hyaline, veins brown, with a brown spot at end of R2+3, R4+5 and M1 ( Fig. 36 ). Abdomen creamy, with brown to ochre spots. Subgenital plate dark brown with sides and centrally light brown ( Fig. 39 ). Clunium brown. Epiproct and Paraprocts pale brown and darker areas. Gonapophyses: V1 brown to cream, V2+3 dark brown and pale brown area; IX sternum cream, with narrow brown marginal area ( Fig. 40 ).

Morphology. As in diagnosis, plus the following: Head ( Fig. 37 ): H/MxW: 1.36; compound eyes large, H/D: 2.59; IO/MxW: 0.74. Outer cusp of lacinial tip broad, with six denticles; Mx4/Mx2: 1.19. Forewings ( Fig. 35 ): L/ W: 2.44. Pterostigma: lp/wp: 4.22, areola postica high and wide with anterior edge rounded: al/ah: 1.99. Hindwing ( Fig. 36 ): l/w: 2.85. Subgenital plate ( Fig. 39 ) broadly triangular, rounded apically and setose as illustrated. Gonapophyses: V1 long, wide proximally, acuminate distally, V2+3 wide proximally, V3 with 14 macrosetae, distal process straight, acuminate, bearing microsetae on surface ( Fig. 40 ). Ninth sternum ( Fig. 40 ). Epiproct triangular, setal field with abundant setae and macrosetae distally. Paraprocts triangular ( Fig. 38 ), with a dense setal field distally, with abundant macrosetae apically; sensory fields with 21 trichobothria on basal rosettes.

Measurements (in microns). FW: 4025; HW: 2850; F: 1000; T: 1700; t1: 700; t2: 82; t3: 124; ctt1: 24; f1: 600; f2: 512.5; f3: 450; f4: 425; Mx4: 250; IO: 480; D: 340; d: 252; IO/d: 1.90; PO: 0.74
