Chinaia peruviana  sp. nov.

Figs 31–40View FIGURES 31 – 40, 46–47View FIGURES 41 – 47

Diagnosis. Pygofer with large sclerotized process arising from the middle third, dorsally curved, hook-like, with pointed apex ( Fig. 35View FIGURES 31 – 40). Subgenital plates, in ventral view, with four macrosetae medially, close to inner margin ( Fig. 36View FIGURES 31 – 40). Aedeagus dorsally curved, “U” shaped, with fork-like bifurcated apex ( Figs 39–40View FIGURES 31 – 40).

Measurements (mm). Male holotype: total length 7.27; crown median length 0.52; transocular width 1.64; interocular width 0.84; frons basal width 0.60; frons length 1.04; pronotum median length 0.76; width between humeri 1.92; mesonotum median length 1.0; mesonotum maximum width 1.24; forewing length 5.96; forewing maximum width 1.36.

General color. Pale yellow to whitish, with orange stains ( Figs 46–47View FIGURES 41 – 47). Head, in frontal view, pale yellow to whitish, without distinct stains, only antennal escapes light orange ( Fig. 32View FIGURES 31 – 40); crown entirely pale yellow without stains, except for conspicuous tentorial pits ( Fig. 31View FIGURES 31 – 40). Pronotum pale yellow with orange stripe along posterior margin not reaching lateral angles ( Figs 31, 33View FIGURES 31 – 40). Mesonotum pale yellow with two approximately triangular brown stains close to the lateral angles, and middle stripe of the same color that does not cross preapical fold ( Figs 31, 33View FIGURES 31 – 40). Forewings yellowish with yellow veins and six orange stains: one at center of clavus, one at apex of clavus, and four on basal and middle thirds, above claval suture: a basal one, two central and one preapical ( Fig. 34View FIGURES 31 – 40). Hindwing brown with red veins. Legs pale yellow to whitish with setae of the same color.

Description. Tentorial pits conspicuous and coronal suture indistinct; frons approximately two times its basal width; forewing about 4.5 times longer than its greatest width; anteapical cells slightly conspicuous apically. Male genitalia: in lateral view, pygofer wider basally, narrowing towards apex and without macrosetae, with large sclerotized process arising from the middle third, dorsally curved, hook-like, with pointed apex ( Fig. 35View FIGURES 31 – 40). Subgenital plates fused only on basal third, length about two times its basal width; in ventral view, with four macrosetae medially, close to inner margin ( Fig. 36View FIGURES 31 – 40). Style moderately long and thickened, apex hook-like, curved ventrally and sclerotized, and with large apical lobe, lateral to hook; two microsetae bellow hook and several setae at apex of apical lobe ( Figs 37–38View FIGURES 31 – 40). Connective cruciform, approximately same length of style, articulate to aedeagus ( Fig. 38View FIGURES 31 – 40). Aedeagus dorsally curved, “U” shaped, with fork-like bifurcated apex, apical gonopore located in the middle of the bifurcation ( Figs 39–40View FIGURES 31 – 40). Anal tube simple, without processes ( Fig. 35View FIGURES 31 – 40). Female unknown.

Geographical distribution. Peru (Loreto).

Specimens examined. Male holotype ( NMNH), with following labels: “ 26.viii.1965, San Antonio, Loreto, PERU, 82, Coll. J.C. Hitchcock Jr. / Chinaia  n. sp. like ornata (Osb.)  except pyg. process” 

Holotype condition. Right side of thorax glued to the triangle. Antennal flagellum with apical half missing.

Right foreleg with the tibia and tarsi missing; left hind leg missing. Forewings and hind wings in perfect state. Abdomen dissected.

Etymology. The name of the species refers to the country of origin of the holotype, Peru.

Notes. Chinaia peruviana  sp. nov. is similar to Chinaia lepida Kramer  and Chinaia ornata (Osborn)  in the apical processes of the pygofer ( Fig. 35View FIGURES 31 – 40), although these processes are larger in the new species than in the later. The aedeagus ( Figs 39–40View FIGURES 31 – 40) is curved dorsally and “U” shaped, like in C. ornata  , but it does not have a long basal apodeme as in C. ornata  . The general coloration, stains and dots of the forewing ( Fig. 34View FIGURES 31 – 40) resemble C. ornata  .
