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 : 34

Myopsocus caliensis n. sp.

( Figs 91–96 )

Diagnosis. Belonging to the assemblage of species that do not present the forewing with the scalloped apical margin, unlike these it presents a pyriform phallosome, with narrow and fused phallobase, wider distally ( Fig. 96 ), external parameres flattened, widened and curved inward, apically separated by short membrane; endophallus elongated, flattened, distally and apically more broadened.

Male. Color. Head ( Fig. 93 ) dark brown, darker genae, clypeus and labrum. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Forewing ( Fig. 91 ) with dark brown spots, with well-marked basal fascia, pterostigma filled with small purple spots that extends outside the margin, while retaining its shape, alar margin dotted, venation poorly differentiated basally and distally marked. Hindwing ( Fig. 92 ) smoked, with veins brown and dotted alar margin. Legs: coxae and trochanter dark brown, femur dark brown with subapical band white-creamy, tibia and tarsi brown. Hypandrium, paraprocts and epiproct dark brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 93 ) H/MxW: 1.25; compound eyes grandes, H/D: 1.74, with interonmatidial setae; vertex with emargination ‘V’-shaped, with slightly pronounced bulge before the epicranial suture. IO/MxW: 0.50. Outer cusp of lacinial tips little wide, with four denticles; Mx4/Mx2: 1.38. Forewings ( Fig. 91 ): L/W: 2.68. Pterostigma: lp/wp: 2.67, areola postica wider than tall, apically angled: al/ah: 1.67. Hindwings ( Fig. 92 ): l/w: 2.62. Paraprocts ( Fig. 94 ) with well-sclerotized conical lateral projection hiding a small membranous tubercle covered setae, sensory fields with 23 trichobothria on basal rosettes. Epiproct ( Fig. 94 ) crescent-shaped, with a transverse dorsal protuberance with superficial small tubercles, distal edge rounded and an apical bulge with four distal setae.

Measurements. FW: 2907.5, HW: 2175, F: 525, T: 1075, t1: 400, t2: 65, t3: 70, ctt1: 19, f1: 675, f2: 462.5, f3: 382.5, Mx4: 165, IO: 266, d: 300, D: 382, IO/d: 0.89, PO: 0.79
