García Aldrete, Alfonso N., Obando, Ranulfo González & Gironza, Nancy Carrejo, 2016, New species of Loneuroides García Aldrete (Psocodea: ' Psocoptera': Ptiloneuridae) from Colombia, and description of the male L. venezolanus García Aldrete, Zootaxa 4093 (1), pp. 103-117 : 104-106

Loneuroides bretanaensis n. sp. Male

( Figs 1–6 )

Diagnosis. Differing from L. ledesmai n. sp., in having the median posterior process of the central sclerite of the hypandrium wide and obtusely concave posteriorly. Differing from L. colombianus n. sp., L. santanderinus n. sp., and L. venezolanus García Aldrete , in having the lateral processes of the central sclerite of the hypandrium slender and acuminate, directed posteriorly. Differing from L. rionegroensis n. sp., in having the central sclerite of the hypandrium with one median posterior process flanked by pointed posterior processes, and by having the forewing M five branched, and the hindwing M three or four branched.

Color (in 80% ethanol). Body pale brown, with ochre and creamy areas. Head pale brown, with brown and creamy areas ( Fig. 3 ). Compound eyes dark brown, ocelli hyaline, with ochre centripetal crescents. Antennae pale brown; maxillary palps cream, Mx4 pale brown distally. Legs pale brown, coxae with proximal and distal brown ochre spots; femur with little apical brown spot. Forewing with a marginal, pigmented band from R4+5 to confluence of Cu2-1A, with hyaline areas on each side of vein ends at wing margin, from M1 to Cu1a and Cu1b; pterostigma pale brown with ochre spots ( Fig. 1 ). Veins pale brown, with dark brown areolae on setal insertions. Abdomen creamy, with ochre subcuticular areas. Epiproct and paraprocts pale cream, with ochre subcuticular areas; hypandrium pale brown.

Morphology. As in diagnosis, plus the following: Forewing M of five branches ( Fig. 1 ), hindwing M of three or four branches ( Fig. 2 ). Head pattern ( Fig. 3 ). Central sclerite of hypandrium ( Fig. 6 ) with median posterior process stout, sides almost parallel, obtusely concave distally, with postero-lateral corners pointed; lateral processes long, slender, with small, median protuberance on outer border, apices pointed, directed posteriorly. Phallosome ( Fig. 5 ) anteriorly Y shaped, side struts fused proximally, with stem short, pointed; arms of the side struts proximally dilated on inner borders; two pairs of endophallic sclerites, anterior pair bow shaped, with proximal ends wide, hooked, and distal ends bearing teeth on inner and outer borders; posterior pair wide proximally, narrowing distally, each arm ending in a hook directed outwards, next to external parameres; a mesal, stout, strongly sclerotized transverse sclerite, deeply concave anteriorly and pointed posteriorly. Paraprocts ( Fig. 4 ) broad, elongate, with field of setae distally, and sensory fields with 23–24 trichobothria in basal rosettes. Epiproct ( Fig. 4 ) convex anteriorly, broadly trapeziform, with setae as illustrated, and a mesal, slender, transverse field of microspines next anterior border.
