Ptiloneura mutisi García Aldrete, González & Carrejo. Female

( Figs 74–79 )

Diagnosis. Close to P. andoque n. sp., differing from it in the pigmented area of the subgenital plate (compare Figs 11 and 77 ), in the shape of v2+3, with a distinct prominence in the inner border, next to the distal process, absent in P. mutisi , and in the shape of the ninth sternum, larger and of three areas in P. andoque , and distinctly smaller and of two areas in P. mutisi (compare Figs 13 and 79 ).

Color. Body dark brown, with cream spots. Head brown, with few pale spots ( Fig. 76 ), compound eyes black, ocelli hyaline, with ochre centripetal crescents. Vertex light brown, with pale brown spots; front with brown spot, with ochre transversal band between the inner borders of each compound eye below the lower edge of the ocellar triangle to the epistomal sulcus. Labrum, anteclypeus, postclypeus and mandibles dark brown. Postclypeus with converging brown slender bands on each side. Genae dark brown with light brown spots. Postgenae light brown (same pattern as in P. andoque ). Antennae: scape and pedicel dark brown, flagellomeres 1-2 light brown, 3-11 brown, with apices cream. Maxillary palps dark brown. Tergal lobes of meso- and metathorax dark brown to ochre. Thoracic pleura brown, with ochre spot. Legs: fore-, middle coxae and trochanters brown, femora brown proximally; hind coxae, trochanters and femora light brown, hind femora with preapical ochre spot; tibiae and tarsi 2-3 pale brown, tarsi 1 light brown. Forewings mostly hyaline ( Fig. 44 ). Hindwings hyaline, veins brown. Abdomen dark brown to ochre, with small, cream irregular spots. Clunium brown; subgenital plate dark brown laterally, hyaline mesally ( Fig. 47 ). Gonapophyses: v1 light brown, with longitudinal band dark brown, v2+3 dark brown to light brown; IX sternum light brown ( Fig. 49 ). Paraprocts and epiproct pale brown ( Fig. 48 ).

Morphology. Head ( Fig. 76 ) H/MxW: 1.32; compound eyes large, H/d: 3.90; IO/MxW: 0.80. Vertex at the same level as the upper border of the compound eyes; outer cusp of lacinial tips broad, with 7-8 denticles. Mx4/Mx2: 1.19. Forewings ( Fig. 74 ) L/W: 2.60; pterostigma: lp/wp: 5.39, elongate, wider in the middle; M seven-branched, M2 forked; areola postica: la/ha: 1.18, tall, broadly triangular, apically rounded. Hindwings ( Fig. 75 ) l/w: 2.84; M three-branched. Subgenital plate ( Fig. 77 ) wide, setose, with posterior border rounded, bearing a row of setae. Gonapophyses ( Fig. 79 ): v1 elongate, wide and acuminate, bearing microspicules on surface; v2+3 with a proximal slender heel, v2 with a row of 3 macrosetae; distal process long, sinuous and acuminate, bearing microspicules on surface. Ninth sternum ( Fig. 79 ) oval, wider anteriorly. Paraprocts ( Fig. 78 ) triangular, apex broadly rounded, with long and short setae posteriorly, sensory fields with 30–32 trichobothria on basal rosettes. Epiproct ( Fig. 78 ) triangular, wide basally, apex broadly rounded, with long and short setae on sides and posteriorly.
