Figs 12–21 , 43–44 Diagnosis. Pygofer with long and slender dorsal process curved downward, with pointed apex ( Fig. 15 ). Subgenital plate with five macrosetae on median and apical thirds close to inner margin ( Fig. 16 ). Aedeagus slender and curved dorsally with pair of apical teeth curved posteriorly and pair of large and spatulate apodemes at base ( Figs 19–21 ). Measurements (mm). Male holotype : total length 7.7; crown median length 0.65; transocular width 1.65; interocular width 0.85; frons basal width 0.65; frons length 1.0; pronotum median length 0.65; width between humeri 1.95; mesonotum median length 1.0; mesonotum maximum width 1.3; forewing length 6.2; forewing maximum width 1.5. General color. Whitish ( Figs 43–44 ). Head, in frontal view, pale yellow to whitish, without distinct stains, only antennal escape, pedicel and clypeus yellowish. Crown whitish, only posterior margin and contour of tentorial pits yellowish ( Fig. 12 ). Proepimerum yellowish at base and whitish at apex. Pronotum pale yellow to whitish without distinct stains ( Figs 12–13 ). Mesonotum whitish with yellowish lateral stains ( Figs 12–13 ). Forewing with basal and middle thirds whitish and opaque; apical third yellowish and hyaline, with short irregular brown stripe at apex of inner and central anteapical cells, and three to five brown spots between second and third apical cells; yellowish venation of forewing visible only at apex ( Fig. 14 ). Hind wing hyaline with yellowish venation at basal and middle thirds and brown on apical third. Legs pale yellow. Description. Tentorial pits distinct and coronal suture indistinct; frons approximately 1.5 times its basal width; forewing about four times longer than its greatest width; anteapical cells slightly conspicuous. Male genitalia: in lateral view, pygofer wider basally, narrowing towards apex and without macrosetae, with long and slender dorsal process curved downward, with pointed apex ( Fig. 15 ). Subgenital plates fused only on basal third, length about two times their basal width; in ventral view, with five macrosetae on median and apical thirds, close to inner margin, apices folded dorsad ( Figs 15–16 ). Style moderately long and thickened, with apex hook-like, curved ventrally and sclerotized, and with large apical lobe lateral to hook; two microsetae bellow hook ( Figs 17–18 ). Connective cruciform, approximately same length of style, articulated with aedeagus ( Fig. 18 ). Aedeagus slender and curved dorsally with pair of apical teeth curved posteriorly and pair of large and spatulate apodemes at base, gonopore apical ( Figs 19–21 ). Anal tube simple, without processes ( Fig. 15 ). Female unknown. Geographical distribution. Ecuador ( Orellana ). Specimens examined. Male holotype ( NMNH ), with following labels: “ Ecuador , Orellana , Transect Ent. 1 Km S Onkonegare Camp., Reserva Etnica Waorani , 00º39’10”S , 076º26’00”W / 22-Jun-96 , T.L.Erwin et al .; Fogging terra firme forest; Lot#1574/ Loan from USNMNH #2037483 ”. FIGURES 12–21. Chinaia longicauda sp. nov. , male holotype: 12 , head, pronotum and mesonotum, dorsal view; 13 , head, pronotum and mesonotum, lateral view; 14 , forewing; 15 , valve, pygofer and anal tube, lateral view; 16 , valve and subgenital plates, ventral view; 17 , style, lateral view; 18 , connective and styles, dorsal view; 19 , aedeagus, lateral view; 20 , aedeagus, dorsal view; 21 , apex of aedeagus, superior view. Holotype condition. Right side of thorax glued to the triangle. Right antennal flagellum with broken apex. Right foreleg glued to triangle, tarsus missing; tarsus of left hind leg missing; the other legs in perfect state. Apex of right forewing broken, other wings in perfect state. Abdomen dissected. Etymology. From the Latin, longus , long; cauda , tail, appendage. Species name refers to the long and slender dorsal process of the pygofer. Notes. Chinaia longicauda sp. nov. can be easily separated from the other species of the genus by the morphology of the pygofer, with a long and slender process ( Fig. 15 ) that resembles the condition found in Chinaia agarista Kramer. Additionally , the morphology of the aedeagus ( Figs 19–21 ) and the color pattern of the forewing ( Fig. 14 ), with few stripes and dots, can quickly differentiate C. longicauda from all the other species of Chinaia .
