description: Ptiloneura caguanensis González, Carrejo & Panche. Male   
(Figs 32–37)  
 Diagnosis. Related to P. andoque n. sp., P. canoae n. sp., and P. hernandezi n. sp., being closer to the former, differing from it in having the forewing marginal pigmented band with hyaline fenestrae at veins ends, in having the lateral processes of the central sclerite of the hypandrium slender and directed posteriorly, in having the side sclerites of the hypandrium posteriorly acuminate, lacking the subapical processes in the inner border shown by P. andoque (compare Figs 5 and 35) and in the shape of the endophallic sclerites, the mesal sclerite being distinctly bigger in P. caguanensis (Fig. 37).   
 Color. Body dark brown, with cream spots. Head brown, with few pale spots (Fig. 34), 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. Postclypeus with converging pale and brown slender bands on each side. Genae dark brown with small pale spots. Postgenae pale brown. Antennae: scape and pedicel brown, flagellomeres pale brown, with apices cream. Maxillary palps brown. Tergal lobes of meso- and metathorax dark brown. Mesothoracic pleura dark brown, pro- and metapleura light brown to cream, with small ochre spots. 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, with a pigmented marginal band from R1 to 2A, and small pale spots at the ends of veins M and Cu, pterostigma dark brown, veins brown. Hindwings hyaline, veins brown. Abdomen dark brown, with small, pale cream irregular spots. Clunium, hypandrium and paraprocts brown, epiproct cream.   
 Morphology. Head (Fig. 34). H/MxW: 1.43; compound eyes large, H/d: 3.85; IO/MxW: 0.78; 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: 1.29. Forewings (Fig. 32) L/W: 2.69; pterostigma: lp/wp: 5.57; M seven branched; areola postica: la/ha: 1.26, tall, narrow, distally rounded. Hindwings (Fig. 33) l/w: 2.92; M three-branched. Central sclerite of the hypandrium with fields of macrosetae on each side of the longitudinal midline (Fig. 35), apices of posterior processes of the central sclerite narrow and with short teeth. Phallosome (Fig. 37) anteriorly Y-shaped; five endophallic sclerites; anterior pair boomerang-shaped; lateral sclerites bow shaped, not widened distally, with rounded apices (Fig. 37). Mesal sclerite wider anteriorly, with posterior, pointed median process. Paraprocts (Fig. 36) oval, with abundant distal setae; sensory fields with 38–40 trichobothria on basal rosettes. Epiproct (Fig. 36) convex anteriorly, broadly rounded posteriorly, with setae as illustrated and a field of microspiculae posteriorly.
