Ptiloneura andoque González, García Aldrete & Carrejo

( Figs 2–13 )

Diagnosis. Related to P. canoae n. sp., P. hernandezi n. sp., and P. caguanensis n. sp., by having the central sclerite of the hypandrium with postero-lateral long processes widely separated ( Fig. 5 ); it is closer to P. caguanensis n. sp. by having the forewings with a marginal pigmented band from R1 to 1A and by having the lateral endophallic sclerites bow shaped.

Male. Color. Body dark brown, with creamy spots. Head brown, with few pale spots ( Fig. 4 ), oblique dark brown bands from the inner margin of each compound eye to the epistomal sulcus, surrounding the antennal fossae. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Vertex pale brown, with pale spots. Postclypeus with converging brown slender bands on each side. Genae dark brown with small pale spots. Postgenae creamy. Antennae: scape and pedicel brown, flagellomeres pale brown, with apices cream. Maxillary palps brown. Tergal lobes of meso- and metathorax dark brown. Thoracic pleura ochre, with light brown areas on pro- and metapleura. Legs: fore-, middle coxae and trochanters dark brown; hind coxae, femora and trochanters cream; fore- and middle femora dark brown proximally, cream distally; tibiae brown, tarsi brown. Forewings hyaline ( Fig. 2 ), with a marginal brown band from R1 to distal half of 1A, veins brown; pterostigma dark brown. Hindwings hyaline ( Fig. 3 ), veins brown. Abdomen dark brown, with small, pale cream irregular spots. Clunium brown, hypandrium and paraprocts dark brown, epiproct cream.

Morphology. Head ( Fig. 4 ). H/MxW: 1.42; compound eyes large, H/d: 3.85; IO/MxW: 0.77; vertex at the same level as the upper border of the compound eyes; outer cusp of lacinial tips broad, with 5–6 short, rounded denticles. Mx4/Mx2: 1.17. Forewings ( Fig. 2 ) L/W: 2.71; pterostigma: lp/wp: 5.52; M seven-branched; areola postica: la/ha: 1.03, tall, narrow, distally rounded. Hindwings ( Fig. 3 ) l/w: 3.65; M three-branched. Central sclerite of the hypandrium with abundant macrosetae on each side of the longitudinal midline ( Fig. 5 ); apices of posterior processes of the central sclerite bidentate. Side sclerites long, narrow, each with an irregular process posteriorly on inner border. Phallosome ( Fig. 7 ) anteriorly Y-shaped; five endophallic sclerites; anterior pair triangular; mesal sclerite broadly trapeziform, with posterior median process pointed; lateral endophallic sclerites bow shaped, dilated distally, with a small pointed process. Paraprocts ( Fig. 6 ) oval, with abundant distal setae as illustrated; sensory fields with 33–35 trichobothria on basal rosettes. Epiproct ( Fig. 6 ) convex anteriorly, broadly rounded posteriorly, with few setae as illustrated and a field of microspiculae posteriorly.

Female. Color. Body, head, legs, wings, epiproct and paraprocts as in the male. Subgenital plate dark brown, hyaline in the middle and posteriorly ( Fig. 11 ). Gonapophyses: v1 hyaline, with long dark brown longitudinal area, v2+3 brown. IX sternum yellowish, with small lateral brown spots and posterior hyaline areas.

Morphology. Head ( Fig. 10 ) H/MxW: 1.38; compound eyes as in the males, H/d: 3.77; IO/MxW: 0.77; vertex at the same level of the upper border of the compound eyes; outer cusp of lacinial tips broad, with 4-5 denticles. Mx4/ Mx2: 1.21. Forewings ( Fig. 8 ) L/W: 2.66; pterostigma: lp/wp: 5.13, long, wider in the middle; M seven branched; areola postica: la/ha: 1.27, tall, narrow, rounded apically. Hindwings ( Fig. 9 ) l/w: 2.96; M three-branched. Subgenital plate ( Fig. 11 ) wide, almost straight posteriorly, setae as illustrated. Gonapophyses ( Fig. 13 ): v1 elongate, slender and acuminate, with abundant spiculae; v2+3 proximally wide, distal process long and acuminate, with abundant spiculae, v2 with a row of three setae; ninth sternum ( Fig. 13 ) of three distinct areas, wider anteriorly, with sides rounded, anterior margin convex, membranous. Paraprocts ( Fig. 12 ) broadly triangular, with field of long and short setae distally; sensory fields with 30-32 trichobothria on basal rosettes. Epiproct ( Fig. 12 ) triangular, wide based, with setae and macrosetae as illustrated.
