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 : 47-50

Myopsocus panchei n. sp.

( Figs 151–156 )

Diagnosis. Belonging to the assemblage of species that does not present the forewing with the apical margin of some of its cells scalloped and hypandrium V-shaped and without subsequent processes ( Fig. 155 ). Unlike these, it presents phallosome piriform, with side struts joined by membrane and widened external parameres with rounded apex and converging medially ( Fig. 156 ).

Male. Color. Head ( Fig. 153 ) brown, darker genae. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Antenna and maxillary palps pale brown. Forewing ( Fig. 151 ) with browns spots, pterostigma brown, filled with small purple spots that extends outside the margin, while retaining its shape, alar margin dotted, veins pale brown. Hindwing ( Fig. 152 ) 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, paraprocts and epiproct brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 153 ): H/MxW: 1.24; compound eyes large, H/D: 1.74; IO/MxW: 0.44. Vertex slightly emarginated, V-shaped wide, below upper level of compound eyes. Outer cusp of lacinial tips broad, with four denticles; Mx4/Mx2: 1.36. Forewings ( Fig. 151 ): L/W: 2.43. Pterostigma: lp/wp: 2.55, areola postica high and wide, apically angled: al/ah: 1.61. Hindwings ( Fig. 152 ): l/w: 2.57. Hypandrium ( Fig. 155 ), anterior border convex; basal section slightly wider than long, postero-lateral angle with short rounded processes, with several macrosetae. Phallosome pyriform, side struts apically curved inward and projected on the base of the external parameres, these well-developed, widened and with rounded margins, converging medially ( Fig. 156 ). Paraprocts ovoid ( Fig. 154 ), with apical acuminate process and field of setae and macrosetae on distal area; sensory fields with 22 trichobothria on basal rosettes. Epiproct ( Fig. 154 ) semioval, with setae, as illustrated.

Material studied. Holotype male. COLOMBIA. Putumayo, Puerto Leguizamo, Resguardo Indigena Tukunaré (Murui–Muina Etnia), Jose’s house trail, 0°07’24.65”N: 74°55’38.11”W. 189m. 8–9.ii.2016. MUSENUV slide code: 31352 . J. Panche. Led light trap in forest canopy.

Etymology. The specific epithet is gratefully dedicated to Jeferson Danois Panche, in recognition to his important work as a collector of Psocoptera species in the departments of Putumayo and Caquetá.
