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 : 50

Myopsocus putumayensis n. sp.

( Figs 157–162 )

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 this one presents, it has a phallosome with side strut basally united by broad sclerotized area, external parameres broad distally, with internal margin strongly curved, apically converging mesally ( Fig. 162 ).

Male. Color. Head ( Fig. 159 ) brown, genae and labrum darker. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Antenna pale brown; maxillary palps dark brown. Forewing ( Fig. 157 ) with brown and hyaline spots, pterostigma brown, alar margin dotted, venation pale brown. Hindwing ( Fig. 158 ) smoked, with veins brown and dotted costal 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, paraprocts, epiproct and phallosome dark brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 159 ): H/MxW: 1.40; compound eyes large, H/D: 1.97x; IO/MxW: 0.630. Vertex markedly emarginated, below upper level of compound eyes. Outer cusp of lacinial tips broad, with four denticles; Mx4/Mx2: 1.45. Forewings ( Fig. 157 ): L/W: 2.44. Pterostigma: lp/wp: 2.15, areola postica, apically angled, as tall as wide: al/ah: 1.02. Hindwings ( Fig. 158 ): l/w: 2.56. Hypandrium some triangular, basally widened, distally rounded ( Fig. 161 ), with several macrosetae. Phallosome with endophallus membranous, with two somewhat elongated sclerites near mesal line ( Fig. 162 ). Paraprocts ovoid, with posterior process curved inward ( Fig. 160 ), a dense field of setae and macrosetae on distal area; sensory fields with 20 trichobothria on basal rosettes. Epiproct ( Fig. 160 ) semioval, with scattered setae and macrosetae in the distal field, as illustrated.

Measurements. FW: 2650, HW: 2012.5, F: 525, T: 975, t1: 380, t2: 55, t3: 72, ctt1: 20, f1: 475, f2: 350, f3: 295, f4: 267.5, f5: 207.5, f6: 177.5, f7: 150, f8: 137.5, f9: 125, Mx4: 168, IO: 300, d: 250, D: 340, IO/d: 1.2, PO: 0.74.
