Lichenomima occidentalis n. sp.

(Figs 43–54)

Diagnosis. Unlike other species related, it has phallosome with side struts basally narrow and fused, distally forcepsshaped, external parameres flattened, basal and apically wider, aedeagus membranous and lobed apically (Fig. 48)

Male. Color. Head (Fig. 45) pale brown, dark brown spot on vertex, clypeus dark brown. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; antennae pale brown to brown; maxillary palps pale brown. Legs: coxae dark brown, fore femur pale brown, middle and posterior femur with a dark brown fringe, another white cream and a small dark brown stain and white-cream fringe in the middle; tibia white-creamy, with brown apex, tarsi 1 white-creamy and brown apex, tarsi 2 and 3 brown. Forewing (Fig. 43) dappled brown, veins dark brown, more visible in the distal part; alar margin, subcostal and anal vein punctate, pterostigma filled with small dark brown spots that extends outside the margin, while retaining its shape, vein m with a dark brown spot in the distal part. Hindwing (Fig. 44) smoked, veins brown and costal margin slightly dotted. Clunium and hypandrium (Fig. 47) dark brown, epiproct and paraprocts brown.

Morphology. As in diagnosis, plus the following: Head (Fig. 45): H/MxW: 1.24; compound eyes large, H/D: 2.68; IO/MxW: 0.63. Vertex straight, compound eyes small compared to other male of the genus (equal proportion to female). Outer cusp of lacinial tips broad, with four denticles; Mx4/Mx2: 1.25. Forewings (Fig. 43): L/W: 2.63. Pterostigma: lp/wp: 2.97, areola postica high, with vertex touching vein M: al/ah: 1.64. Hindwings (Fig. 44): l/w: 2.71. Hypandrium subtriangular to V-shaped, with rounded apical margin (Fig. 47), with setae and macrosetae as illustrated. Phallosome (Fig. 48). Paraprocts with two small tubercles, one membranous medial and covered with setae and the second covered with spicules and short setae, with a lateral internal projection sclerotized curved upwards, (asta) process short, strongly curved and four distal setae (Fig. 46). Sensory fields with 27 trichobothria on basal rosettes. Epiproct (Fig. 46) crescent-shaped with distal embossed and setae transversely distributed distally.

Female. Color. As in males. Subgenital plate and gonapophyses brown to pale brown.

Morphology. As in diagnosis, plus the following: Head (Fig. 51). H/MxW: 1.20; Vertex almost straight, slightly above upper level of compound eyes, these smaller than in males, H/D: 2.90, widely separated, IO/MxW: 0.69. Outer cusp of lacinial tips little wide, with five denticles; Mx4/Mx2: 1.05. Forewings (Fig. 49): L/W: 2.59. Pterostigma: lp/wp: 3.11, areola postica almost as tall as wide, angled apically: al/ah: 1.56. Hindwings (Fig. 50): l/w: 2.65. Paraprocts (Fig. 52) subrectangular, with short outer margin, distally with rows of setae and macrosetae; lateroapical area with group of setae and small setae; sensory fields with 31 trichobothria on basal rosettes. Epiproct (Fig. 52) subtrapezoidal, broadly rounded apically and basal margin almost straight, distal field with setae and macrosetae, apical margin with few setae. Subgenital plate (Fig. 53). Gonapophyses typical to family (Fig. 54), V1 apically acuminate, with microsetae, V2 distally acuminate, about twice the length of V1, V3 oval and with setae and macrosetae as illustrated.
