Chinaia modesta  sp. nov.

Figs 22–30View FIGURES 22 – 30, 45View FIGURES 41 – 47

Diagnosis. Pygofer, in lateral view, wider basally, narrowing towards apex and without macrosetae or processes ( Fig. 25View FIGURES 22 – 30); subgenital plates, in ventral view, with two macrosetae medially, close to inner margin ( Fig. 26View FIGURES 22 – 30); aedeagus simple, without processes or lateral flaps, curved dorsally, “U” shaped; gonopore located in a “V” shaped apical opening ( Figs 29–30View FIGURES 22 – 30).

Measurements (mm). Male holotype: total length 5.87; crown median length 0.50; transocular width 1.45; interocular width 0.75; frons basal width 0.55; frons length 1.25; pronotum median length 0.65; width between humeri 1.65; mesonotum median length 0.60; mesonotum maximum width 1.0; forewing length 5.0; forewing maximum width 1.40.

General color. Yellow with most of hind wing red ( Fig. 45View FIGURES 41 – 47). Head, in frontal view, without distinct stains, except for upper two thirds of gena and maxillary plate, whitish, close to compound eye; maxilla with yellow lower third ( Fig. 23View FIGURES 22 – 30); crown yellow, without stains ( Fig. 22View FIGURES 22 – 30); pronotum with narrow orange stripe close to posterior margin and with lateral margins of the same color ( Fig. 22View FIGURES 22 – 30). Proepisternum orange ( Fig. 23View FIGURES 22 – 30); mesonotum with very narrow orange stripe on lateral margins ( Fig. 22View FIGURES 22 – 30). Forewing ( Fig. 24View FIGURES 22 – 30): clavus with yellow basal half; apex of clavus and entire middle third of wing red, apical third yellowish, being the only hyaline portion of the wing; with three slender brown stripes: one on middle area of clavus, and two on middle third, above claval suture, the most basal slightly longer than the one close to base of apical cells; three lilac stains also on middle third, two smaller close to longer brown stripe and one larger, close to the other brown stripe, above apex of clavus; a row of three brown small dots on apical third, between second and third apical cells; red venation. Brown hind wing with red venation. Yellow legs with setae of the same color.

Description. Tentorial pits distinct and coronal suture indistinct; frons approximately two times its basal width; forewing about 3.5 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 or processes; posterior margin apparently truncated (it seems to be broken in the holotype) ( Fig. 25View FIGURES 22 – 30). Subgenital plates fused only on basal third, approximately as long as pygofer, length about two times its basal width; in ventral view, with two macrosetae medially, close to inner margin ( Fig. 26View FIGURES 22 – 30). Style moderately long and thickened, with apex hooklike, curved ventrally and sclerotized, and with large apical lobe, lateral to hook; two microsetae bellow hook ( Figs 27– 28View FIGURES 22 – 30). Connective cruciform, approximately same length of style, articulate to aedeagus ( Fig. 28View FIGURES 22 – 30). Aedeagus simple, without processes or lateral flaps, curved dorsally, “U” shaped; gonopore located in a “V” shaped apical opening ( Figs 29–30View FIGURES 22 – 30). Anal tube simple, without processes. Female unknown.

Geographical distribution. Brazil (Amazonas).

Specimens examined. Male holotype ( INPA), with following labels: “ BRASIL, Amazonas, Manaus, R.[eserva Florestal Adolpho] Ducke , 26 Km NE de Manaus, xi.1988, Arm.[adilha] Suspensa, 20m, J.A. Rafael leg. ”. 

Holotype condition. Glued direct to the entomological pin by the dorsal part of the pronotum, the pin is not well positioned on the right side of pronotum. Left antenna broken at base of flagellum. Left hind leg missing. Abdomen dissected.

Etymology. From the Latin, modestus, moderate, gentle, unassuming, chaste. The species name is allusive to the male genitalia, especially to the pygofer and aedeagus, both of which are simpler than in other species of Chinaia  , lacking any processes or flaps.

Notes. Chinaia modesta  sp. nov. is very similar to Chinaia bidentata Chiamolera & Cavichioli  in the general coloration and male genitalia, although it differs from C. bidentata  in by the morphology of the pygofer ( Fig. 25View FIGURES 22 – 30) and aedeagus ( Figs 29–30View FIGURES 22 – 30). The aedeagus of C. modesta  does not have any processes, and in C. bidentata  it has preapical and apical processes. Differences in the size of the forewing stripes and in the number of small dots present on apical third between the second and third apical cells of the forewing were also observed ( Fig. 24View FIGURES 22 – 30).
