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.
