Chinaia maranhensis sp. nov.

( Figs. 1–9 )

Specimens examined. Male holotype deposited at the Entomology Collection Pe. Jesus Santiago Moure, Departamento de Zoologia, Universidade Federal do Paraná (DZUP), with following labels: BRASIL, Maranhão, Imperatriz, Ribeirãozinho, 25.viii.1989 (hand written white label)/ Malayse trap/ F. F. Ramos [leg.] (printed white labels)/ Holotype Chinaia maranhensis Marques­Costa & Cavichioli (printed red label).

Measurements (mm). Male holotype: total length 6.6; crown medium length 0.5; transocular width 1.55; interocular width 0.8; pronotum medium length 0.7; width between umeri 1.75; scutellum medium length 0.8; scutellum maximum width 1.0; forewing length 5.8; forewing maximum width 1.5.

General color. Yellow marked with orange; crown yellow with light­orange bands on lateral margins and a dark­orange band on the posterior margin ( Fig. 1 ); front entirely yellow; scape and pedicel marked with orange; gena and basal half of maxillary plates with whitish coloration; proepimeron and apical half of maxillary plates, clypeus and lora with narrow orange band a continuation of band on posterior margin of pronotum, remainder of clypeus and lora yellow ( Fig. 2 ). Pronotum with orange band on posterior margin ( Fig. 1 ). Scutellum almost entirely orange, with two small medium yellow markings and lateral extremities also yellow ( Fig. 1 ). Forewings with yellow claval area with two orange spots: one at center and other near claval suture apex; area above claval suture basad of anteapical portion with large orange spot and 3–4 small orange red spots; forewing apex yellow and hyaline with 2–4 small dark­brown dots ( Fig. 3 ). Hindwings brownish with reddish venation.

Description. Structural characters as in generic description. Forewing about four times longer than greatest width. Male genitalia: in lateral view, pygofer basally wide, narrowing towards apex and without setae; posterior margin with small sclerotized process with apex approximately truncated; ventral margin membranous on apical third and little differentiated ( Fig. 4 ). Subgenital valve partially fused with subgenital plates, with posterior margin strongly emarginated ( Fig. 5 ). Subgenital plates strongly concave, narrowed apically, length about two times basal width; apex rounded with microsetae and larger seta close to inner margin ( Fig. 5 ); in lateral view, without apical tooth. Styles moderately long and thickened, with apex hooklike, curved ventrally and sclerotized; apex of hook not bifurcated; microsetae on the ventral portion of the hook; apical lobe with microsetae; outer and inner margins slightly irregular ( Figs. 6–7 ). Connective cruciform, about 2/3 style length, medially sclerotized, with lateral branches thickened and central branch basally narrowed ( Fig. 7 ). In lateral view, aedeagus J­shaped, narrowed and sclerotized ( Fig. 8 ); base more enlarged, with a bifurcation whose branches are linked by a membrane; shaft with serrated margins on apical portion and pair of spine­like apical processes with ventral margin serrated, connected by membrane; apical gonopore, opening between the processes ( Figs. 8–9 ). Female unknown.

Holotype condition. Glued on an entomological triangle and covered by scales of Lepidoptera. Antennae broken. Right forewing broken in the claval area; left forewing broken at the apex. Left prothoracic and mesothoracic legs broken, the others glued on the triangle. Abdomen dissected.

Etymology. The species name refers to the location (the Brazilian State) where the holotype was collected.
