Myopsocus insularis n. sp.

( Figs 133–144 )

Diagnosis. Belonging to the assemblage of species that do not present the forewing with the scalloped apical margin, unlike these it presents phallosome elongated ring-shaped, pointed basally and apically rounded, aedeagus medial bar-shaped narrower than external parameres and hinged to the phallobase ( Fig. 138 ). Endophallus membranous. Subgenital plate subrectangular with apical lobe funnel-shaped and a pair of apical setae ( Fig. 143 ).

Male. Color. Head ( Fig. 135 ) pale brown with dark brown spots on front and postclypeus. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Legs: coxae brown, trochanter creamy, femur brown with a subapical band white-cream, tibia white-cream with brown apical band, tarsus 1 white-cream with a basal band brown, tarsi 2 and 3 brown. Forewing ( Fig. 133 ) spotted, with brown spots darker on cell R 5 and discoidal cell (M). Hindwings ( Fig. 134 ) smoked with brown veins. Hypandrium dark brown. Epiproct and paraprocts little pigmented.

Morphology. As in diagnosis, plus the following: Head ( Fig. 135 ): H/MxW: 1.29; compound eyes grandes, H/D: 1.64, with interonmatidial setae; vertex slightly emarginate, V-shaped; IO/MxW: 0.46. Outer cusp of lacinial tips little wide, with four denticles; Mx4/Mx2: 1.29. Forewings ( Fig. 133 ): L/W: 2.44. Pterostigma: lp/wp: 3.33, areola postica wider than tall, apically angled: al/ah: 0.94. Hindwings ( Fig. 134 ): l/w: 2.54. Hypandrium ( Fig. 137 ) trapezoidal, rounded distally, with three pairs of small teeth and an apical middle projection with two setae. Paraprocts ( Fig. 136 ) with short sclerotized process directed downward and slight curvature and a short apodeme directed upwards; sensory fields with 20 trichobothria on basal rosettes. Epiproct ( Fig. 136 ) semioval, with sclerotization on the top edge.

Measurements. FW: 2687.5, HW: 2050, F: 557.5, T: 1010, t1: 420, t2: 70, t3: 84, ctt1: 18, f1: 600, f2: 420, f3: 222.5, Mx4: 168, IO: 250, d: 317, D: 430, IO/d: 0.79, PO: 0.74

Female. Color. As in males. Paraprocts, epiproct and gonapophyses slightly pigmented.

Morphology. As in diagnosis, plus the following: Head ( Fig. 141 ). H/MxW: 1.18; Vertex somewhat sinuous, slightly above upper level of compound eyes, these smaller than in males, H/D: 2.67, widely separated IO/MxW: 0.68. Outer cusp of lacinial tips little wide, with four denticles; Mx4/Mx2: 1.25. Forewings ( Fig. 139 ): L/W: 2.56. Pterostigma: lp/wp: 2.89, postic areola almost as tall as wide, apically angled: al/ah: 1.16. Hindwings ( Fig. 140 ): l/w: 2.61. Paraprocts ( Fig. 142 ) subrectangular, with short outer margin, distally and apical margin with rows of setae and macrosetae; rounded external lateroapical angle; sensory fields with 18 trichobothria on basal rosettes. Epiproct ( Fig. 142 ) subtriangular, broadly rounded apically and basal margin slightly convex medially, distal field with setae and four macrosetae, apical margin with few setae. Subgenital plate ( Fig. 143 ). Gonapophyses typical to family ( Fig. 144 ), V1 apically acuminate, V2 distally acuminate, almost three times the length of V1, V3 oval and with setae and macrosetae as illustrated.

Measurements. FW: 2475, HW: 1850, F: 500, T: 900, t1: 350, t2: 50, t3: 65, ctt1: 16, f1: 425, f2: 325, f3: 275, Mx4: 150, IO: 370, d: 166, D: 240, IO/d: 2.23, PO: 0.69.
