Carrejo, Nancy, Obando, Ranulfo González, Aldrete, Alfonso Neri García & Mendivil, Julián, 2021, New species of Goja Navás (Psocodea: ‘ Psocoptera’: Epipsocidae) from Colombia Mexico and Peru, Zootaxa 4903 (4), pp. 501-541 : 508-512

Goja caucana n. sp.

( Figs 12–22 )

Diagnosis. Forewing R2+3 unbranched, R4+5 four-branched. M eight-branched. Similar to species with hindwing R4+5 branched or not; M three-five branched, M4, M6 and M7 forked. A long spur vein in Rs directed backward. Hindwing Rs two-branched, M five branched ( Fig. 12 ). Anterior endophallic sclerites slender, slightly curved outward, directed anteriorly; posterior endophallic sclerites inverted U-shaped, outer arms acuminate ( Fig. 17 ). Female IX sternum broadly oval, wider anteriorly, spermapore near the posterior border ( Fig. 22 ). Similar to G. munchinquensis n. sp., from which it differs in that the hyaline areas of the forewing are of different size in both species (compare Figs 12 and 67 ), the branching of the forewing Rs are different in the two species, and the former has M with eight primary branches vs. M of three primary branches in the latter (compare Figs 12 and 67 ); also, G. caucana has a spur vein directed backward in Rs, and the hindwing M is five branched vs. absence of a spur vein in the forewing Rs of G. munchinquensis , and hindwing M of two branches. The phallosome is short, with the arms of the aedeagal arch curved, and the endophallic sclerites small and slender in G. caucana vs. phallosome long, with the arms of the aedeagal arch S-shaped, and the endophallic sclerites are large and stout.

Thorax brown, pronotum pale brown, with brown spots; tergal lobes of meso and metathorax with dark brown spots, mesopleura with dark stripes. Legs: coxae, tibia and tarsi brown, fore- coxae pale brown, trochanters and femora cream. Forewings ( Fig. 12 ), brown, with hyaline areas as illustrated, pterostigma hyaline in the middle, veins dark brown. Hindwings ( Fig. 13 ), pale brown, with a yellowish hue, veins brown. Abdomen pale brown, with cream and ochre spots. Hypandrium brown, darker on sides; epiproct and paraprocts pale brown. Phallosome brown, with endophallic sclerites and aedeagal arch dark brown.

Hypandrium ( Fig. 16 ), posteriorly concave in the middle, setose as illustrated. Phallosome ( Fig. 17 ) with side struts straight distally, slender, broad basally, curved inward; aedeagal arch slender, with triangular posterior process and rounded apex; external parameres dilated, apically truncate, bearing pores. Paraprocts ( Fig. 15 ), oval, with a macrosetae near sensory field, and a distal setal field as illustrated, one macrosetae distally spatulate; sensory fields with 27 trichobothria on basal rosettes. Epiproct ( Fig. 15 ) wide, convex anteriorly, rounded posteriorly, one macroseta mesally, two lateral macrosetae, minute spicules and distal setae as illustrated.
