Nieto, Julián Alexander Mendivil, Aldrete, Alfonso Neri García & Obando, Ranulfo González, 2017, Seven new species of Loneura Navás (Insecta: Psocodea: ‘ Psocoptera’: Ptiloneuridae) from Valle del Cauca, Colombia, Zootaxa 4227 (4), pp. 495-523 : 513-515

Loneura quimbaya n. sp. Male

( Figs 51–55 )

Diagnosis. Belonging in Group I, Subgroup IB ( García Aldrete et al. 2011 b); related to L. monserrate , from which it differs in having the posterior projections of the central sclerite of the hypandrium slender, with ends pointed, curved, with a wider concavity between them; each half of the central sclerite of the hypandrium bears a wide field of long macrosetae. The side sclerites have a row of setae along the inner border, the forewing M is five branched, with M5 distally forked, and the hindwing M is three branched (compare with the corresponding figures of L. monserrate in this paper).

Color (in 80% ethanol). Body dark brown. Head ( Fig. 52 ) with two dark brown oblique bands, from the inner margin of each compound eye to epistomal sulcus, surrounding the antennal fossae, a small band reaches the ocellar triangle. Compound eyes dark brown, almost black; ocelli hyaline. Vertex with dark brown areas of irregular size and shape to the sides of the epicranial suture and close to the inner upper edge of the compound eyes. Postclypeus with dark and light brown converging thin bands, forming a broad V-shaped area. Anteclypeus brown, paler on the sides. Labrum dark brown. Genae pale. Postgenae light cream, with small brown spots. Antennae: scape and pedicel brown; flagellum light brown. Mx 1–2 cream; Mx 3 brown; Mx 4 brown, with dark brown apical third. Tergal lobes of meso and metathorax dark brown. Thoracic pleura dark brown with small white spots. Legs: fore- and mid- coxae and trochanters brown; hind coxae and trochanters cream; fore- femora cream, with basal third brown; mid- femora brown proximally and cream distally; hind femora cream, with brown spot; tibiae cream, distally brown; tarsus 1 cream; tarsi 2–3 brown. Forewings hyaline, with brown marginal band from R 4+5 to 1A and 2A as illustrated; pterostigma brown, with a central hyaline area; R2+3 with a distal spot at wing margin. Hindwings with pale brown spots at vein ends. Abdomen dark brown with small, white and cream spots laterally. Hypandrium dark brown. Epiproct and paraprocts pale cream.

Morphology. As in diagnosis, plus the following: Head ( Fig. 52 ) H/MxW: 1.51; large compound eyes, H/d: 2.65; IO/MxW: 0.79; vertex at the same level as the upper margin of the compound eyes; outer cusp of lacinial tip broad, with 10 denticles. Forewings ( Fig. 51 ) L/W: 2.58; pterostigma: lp/wp: 5.33, elongate, wider in the middle; M five branched, M5 forked; areola postica: la/ha: 1.34, high, apically rounded. Hindwings ( Fig. 51 ) l/w: 2.82; M three branched. Central sclerite of the hypandrium ( Fig. 54 ) with two posterior projections, narrowing distally, acuminate; side sclerites elongate, widely separated from the central one. Phallosome ( Fig. 55 ) V-shaped anteriorly; each arm of side struts with a broad, rounded process proximally on inner edge; external parameres curved, elongate, distally rounded; two pairs of endophallic sclerites; anterior pair bow-shaped, proximally with a pointed process directed inward, distally widely dilated, acuminate; posterior pair M shaped, with outer arms long, distally acuminate. Paraprocts ( Fig. 53 ) broad, oval, with macrosetae and short setae posteriorly; sensory fields with 23 trichobothria on basal rosettes. Epiproct ( Fig. 53 ) wide, broadly rounded posteriorly, setae as illustrated.
