Diagnosis

Coloration ( Fig. 11G View Fig ) of head and pronotum reddish-brown without black maculae, forewing costal margin with narrow light yellow macula on anterior third, depigmented (white) macula on apical third absent. Style ( Fig. 6K View Fig ) with dentiform process near base of blade; dorsal margin strongly produced medially, forming a triangular process. Aedeagus ( Fig. 6L–M View Fig ) without processes near base; shaft compressed, with pair of long subapical processes directed basally, branched near base, with ventral ramus half as long as dorsal ramus; apex rounded with pair of short spiniform processes directed dorsally.

Etymology

The new species name is in honor to Prof. Dr José Roberto Pujol Luz of the Universidade de Brasília who collected the holotype.

Description

Male

MEASUREMENTS. Holotype male: total length 7.1 mm.

COLORATION. Dorsal portion of head and thorax reddish ( Figs 6A, C View Fig , 11G View Fig ); ventral portion yellow ( Figs 6B–C View Fig , 11H View Fig ). Crown ( Fig. 6A View Fig ) without markings; eyes and ocelli red. Pronotum ( Fig. 6A View Fig ) with lateral margins black. Scutellum yellowish. Face ( Fig. 6B View Fig ) with frons reddish. Forewing ( Fig. 6D View Fig ) costal margin dark brown, long and slender yellow macula on anterior half and apical fourth; appendix smoky with median whitish macula. Legs ( Figs 4C View Fig , 11H View Fig ) yellow, without black markings.

STRUCTURE. Head in dorsal view ( Fig. 6A View Fig ): median length of crown as long as half interocular width; transocular width of head 7.5 tenths of humeral width of pronotum; in lateral view ( Fig. 6C View Fig ), with anterior margin moderately thin, with 5–6 well developed carinae. Forewing ( Fig. 6D View Fig ) with inner discal cell very short, one-third as long as outer discal cell; apex slightly tapered. Profemur AV row with 4–5 setae restricted to basal half and PV row with 1 apical seta. Protibia PD row with 3 long setae and apical PD 1 seta developed; PV row developed, with 8 setae increasing in thickness and length towards apex. Metatibia rows PD, AD, and AV with 18–19, 13, and 12 macrosetae, respectively. Metatarsomere I apex with 3 platellae. Metatarsomere II apex with 2 apical platellae. Other characteristics as in the generic description.

MALE TERMINALIA. Sternite VIII ( Fig. 6E View Fig ) 1.3× as wide as long; lateral margins excavated at base, forming a triangular projection; apex broadly rounded. Valve ( Fig. 6F View Fig ) 3.1× as wide as long; posterior margin almost straight. Pygofer ( Fig. 6G View Fig ), in lateral view, 1.7× as long as maximum height; ventral margin with rounded protrusion near midlength; posterodorsal and ventral margins rounded; macrosetae distributed on dorsoapical quadrant; apex slightly tapered and rounded. Subgenital plate ( Fig. 6G View Fig ), in lateral view, surpassing half length of pygofer; in ventral view ( Fig. 6H View Fig ), 3.5× as long as wide; inner margin straight; external margin rounded on basal half; external margin with long filiform setae; apex strongly tapered and weakly sclerotized. Connective ( Fig. 6I View Fig ) Y-shaped; arms produced laterally; stalk shorter than maximum width of arms, widened apically; median keel weakly developed. Style ( Fig. 6J View Fig ), in dorsal view, with outer lobe reduced and rounded; apical portion directed outward; in lateral view ( Fig. 6K View Fig ), ventral margin not serrated, with dentiform process near base of blade; dorsal margin strongly produced on basal half, forming a triangular process; apical portion slender, curved dorsally; apex acute. Aedeagus ( Fig. 6L–M View Fig ) preatrium not developed; dorsal apodeme strongly elongated laterally, forming divergent and truncated apices; shaft compressed, curved dorsally; pair of long subapical processes directed basally, branched near base, ventral ramus half as long as dorsal ramus; apex rounded with pair of short spiniform processes directed dorsally.

Female

Unknown.

Remarks

Costanana luzi sp. nov. is most similar to C. praecellens in having the same color pattern ( Figs 11G–H View Fig , 13C–D View Fig ) and the aedeagal shaft compressed and bearing a pair of subapical processes branched near the base ( Fig. 6L View Fig ), and the apex of the aedeagus rounded with pair of short spiniform processes directed dorsally ( Fig. 6M View Fig ). The new species can easily be separated from C. praecellens in having the style with a process on the dorsal margin of the blade and the distal portion longer and distinctly more curved ( Fig. 6K View Fig ), and the branched subapical process of the aedeagus with the ventral ramus half as long as the dorsal ramus ( Fig. 6L–M View Fig ).
