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 : 47

Myopsocus katios n. sp.

( Figs 145–150 )

Diagnosis. Belonging to the assemblage of species that does not present the forewing with the apical margin of some of its cells scalloped, but unlike these it presents a basally broadened phallosome, with narrow external parameres ( Fig. 150 ) and epiproct with convex anterior margin, projected onto the clunium ( Fig. 148 )

Male. Color. Head ( Fig. 147 ) brown, genae darker. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Antenna pale brown; maxillary palps brown. Forewing ( Fig. 145 ) with dark browns and pale brown spots, extensive hyaline areas; pterostigma brown, filled with brown spot that extends outside the margin, while retaining its shape, alar margin dotted, veins light brown to brown. Hindwing ( Fig. 146 ) smoked, with veins brown and dotted alar margin. Legs: coxae and trochanter dark brown, femur dark brown proximally, light brown distally, with subapical brown spot, tibia and tarsi pale brown, t2–t3 darker. Hypandrium and phallosome brown, paraprocts and epiproct pale brown to light brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 147 ): H/MxW: 1.29; compound eyes large, H/D: 1.82; IO/MxW: 0.52. Vertex slightly emarginated, below upper level of compound eyes. Outer cusp of lacinial tips broad, with four denticles; Mx4/Mx2: 1.56. Forewings ( Fig. 145 ): L/W: 2.65. Pterostigma: lp/wp: 2.41, areola postica almost as tall as wide, apically angled: al/ah: 1.12. Hindwings ( Fig. 146 ): l/w: 2.73. Hypandrium trianguliform, rounded apically ( Fig. 149 ), anterior border concave; with several macrosetae. Phallosome apically rounded, aedeagal arch undifferentiated from external parameres ( Fig. 150 ), side struts short, broad basally, curved inward, endophallus membranous. Paraprocts ovoid ( Fig. 148 ), with short, robust apical process directed inward, field of setae and macrosetae on distal area; sensory fields with 21 trichobothria on basal rosettes. Epiproct with anterior margin strongly convex, projected over clunium ( Fig. 148 ), sparse setae field, as illustrated.

Measurements. FW: 2557.5, HW: 1957.5, F: 500, T: 967.5, t1: 336, t2: 67, t3: 72, ctt1: 15, f1: 525, f2: 400, Mx4: 140, IO: 265, d: 270, D: 363, IO/d: 0.98, PO: 0.74.

Material studied. Holotype male. COLOMBIA. Chocó, National Natural Los Katios , 7°51’12.3”N: 77°09’11.0”W. 33m. 25–26.ii.2017. MUSENUV slide code: 31350 . N. Carrejo, R. González. J. Mendivil. Led light trap in forest canopy . Paratype: 1 male, same data as holotype. MUSENUV slide code: 31351

Etymology. The specific epithet is a noun in apposition, and makes reference to the National Natural Park Katios ( Colombia), where the holotype was found.
