González-Obando, Ranulfo, Calderón-Martínez, Nadia R. & Carrejo-Gironza, Nancy S., 2023, New species of Myopsocidae (Insecta: Psocodea: “ Psocoptera ”) from Colombia, Zootaxa 5377 (1), pp. 1-61 : 36-39

Myopsocus colombianus n. sp.

( Figs 109–114 )

Diagnosis. Belonging to the assemblage of species with the posterior margin of the forewings scalloped, but unlike these it presents hypandrium more broadened basally and distally with two short lateroapical processes widely separated ( Fig. 113 ). On the other hand, its phallosome is elongated, with side struts basally close together and connected by a narrow membrane, external parameres subparallel, apically widened and separated by membrane, the endophallus is membranous, with two medial elongated endophallic sclerites ( Fig. 114 ).

Male. Color. Head pale brown ( Fig. 111 ), with scattered dark brown spots. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Antenna pale brown; Maxillary palps: Mx1–3 cream, with dark brown spots, Mx4 dark brown. Forewing ( Fig. 109 ) with brown spots and some hyaline areas, pterostigma dark brown, darker distally; alar margin and some veins dotted. Hindwings ( Fig. 110 ) smoked, brown veins and dotted costal margin. Legs: coxae and trochanter dark brown, femora dark brown proximally, light brown distally, with subapical brown spot, tibiae and tarsi pale brown, t2–t3 darker. Hypandrium, paraprocts, epiproct and phallosome brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 111 ): H/MxW: 1.36; compound eyes large, H/D: 1.75, with interommatidial setae; IO/MxW: 0.55. Vertex emarginated, V-shaped widened, below upper level of compound eyes. Outer cusp of lacinial tips broad, with five denticles; Mx4/Mx2: 1.15. Forewings ( Fig. 109 ): L/W: 2.39. Pterostigma: lp/wp: 1.86, areola postica high and, apically angled: al/ah: 1.3; posterior margin of cells M1 and M2 scalloped. Hindwings ( Fig. 110 ): l/w: 2.53. Hypandrium with abundant macrosetae as illustrated ( Fig. 113 ). Phallosome elongated, side struts connected anteriorly by membrane, external parameres parallel, apically widened and separated by membrane, endophallus membranous, with two medial elongated endophallic sclerites ( Fig. 114 ). Paraprocts subtriangular ( Fig. 112 ), with thick laterodistal process directed inward, setae as illustrated; sensory fields with 22 trichobothria on basal rosettes. Epiproct ( Fig. 112 ) semioval, crescent shaped, with setae scattered in the distal field, as illustrated.

Etymology. The specific epithet is named in honor of Colombia, because it apparently has a wide distribution in this country.
