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 : 530-532

Goja tacanaensis n. sp. Male

( Figs 94–99 )

Diagnosis. Forewing R2+3 and R4+5 unbranched. M four-branched, M3 and M4 distally forked; a crossvein proximally joining them. Hindwing Rs and M two-branched. Head with two ochre transverse bands, one between the compound eyes, enclosing the ocellar triangle, and the other between the genae, as in G. moyai and G. vittata , both by Casasola González & García Aldrete. Anterior endophallic sclerites with a slender, acuminate process directed posteriorly; posterior endophallic sclerites with stout processes slightly curved outward, blunt ended. It is similar to G. omiltemensis Casasola González & García Aldrete , differing from it in the head pattern of pigmentation, in the forewing venation, and in the endophallic sclerites.

Color (in 80% ethanol). Body brown, with pale spots. Head light brown ( Fig. 96 ). Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Maxillary palps pale brown. Antennae pale brown. Thorax brown, pronotum light brown; tergal lobes of meso- and metathorax brown with dark brown spots, mesopleura pale brown, with ochre brown band. Legs brown. Forewings ( Fig. 94 ), light brown, pterostigma with proximal and distal pale brown bands, veins brown. Hindwings ( Fig. 95 ) hyaline, veins pale brown. Abdomen tergum ochre; sternum cream. Clunium, epiproct, paraprocts and hypandrium dark brown. Phallosome with endophallic sclerites, side struts and aedeagal arch brown.

Morphology. As in diagnosis, plus the following: Head: H/MxW: 1.73; compound eyes, H/D: 3.62; IO/MxW: 0.67. Outer cusp of lacinial tips broad, with eight denticles. Forewings ( Fig. 94 ): FW/W: 2.75. Pterostigma elongate: lp/wp: 2.75, areola postica low, almost twice as long as tall: al/ah: 1.81. Hindwings ( Fig. 95 ): HW/w: 3.39. Hypandrium ( Fig. 98 ) narrow, rounded posteriorly, setae as illustrated. Phallosome ( Fig. 99 ) obtusely concave anteriorly; side struts straight, narrow, wide based; aedeagal arch with rounded apex, without apical process; external parameres well developed, membranous, joined to the side struts, wide, rounded posteriorly, with pores. Paraprocts ( Fig. 97 ), oval, with setae and macrosetae on distal field; sensory fields large, with 33 trichobothria on basal rosettes. Epiproct ( Fig. 97 ) wide, semioval, rounded posteriorly, with three macrosetae mesally; distal setal field as illustrated.

Measurements. FW: 4125, HW: 3250, F: 1075, T: 1850, t1: 850, t2: 250, ctt1: 34, IO: 370, D: 263, d: 210, IO/d: 1.76, PO: 0.80.
