Figs 9 View Fig , 12E–F View Fig
Diagnosis
Coloration ( Fig. 12E View Fig ) of crown black with anterior margin red, pronotum brown with small black maculae, forewing costal margin with narrow light yellow macula on anterior third and small depigmented (white) macula on apical third. Style ( Fig. 9K View Fig ) slender and slightly broadened subapically, without processes near base of blade or apical portion. Aedeagus ( Fig. 9L–M View Fig ) shaft long and slender, cylindrical, curved anterad, without apical or subapical processes; pair of long and slender processes arising from basal third, parallel to shaft and slightly surpassing apex, abruptly enlarged at midlength.
Etymology
The species epithet refers to the anterior margin of head being red.

Description
Male
MEASUREMENTS. Holotype male: total length 5.0 mm. Paratype male (n = 1) 5.0 mm.
COLORATION. Dorsal portion head and thorax reddish-brown ( Figs 9A, C View Fig , 12E View Fig ); ventral portion yellow ( Figs 9B–C View Fig , 12F View Fig ). Crown ( Fig. 9A View Fig ) black; anterior margin red; ocelli red. Face ( Fig. 9B View Fig ) with frons black; lorum black to dark brown; gena dark brown between eye and frons; clypeus dark brown except apex yellow. Pronotum ( Fig. 9A View Fig ) with black irregular maculae near anterior and lateral margins; lateral margins yellow. Mesonotum ( Fig. 9A View Fig ) lateral angles black; pair of black maculae submedially. Forewing ( Fig. 9D View Fig ) costal margin with elongate narrow light yellow macula on anterior third, small depigmented (white) macula on outer apical cell, remaining portion black; veins outlined by dark brown; outer half of corium, apex and appendix smoky. Legs ( Fig. 11B View Fig ) yellow, without black markings.
STRUCTURE. Head in dorsal view ( Fig. 9A View Fig ): median length of crown as long as half interocular width; transocular width of head 8.5 tenths humeral width of pronotum; in lateral view ( Fig. 9C View Fig ), with anterior margin moderately thick, with 5–6 well developed carinae. Forewing ( Fig. 9D View Fig ) with inner discal cell half long as outer discal cell; apex rounded. 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 20–23, 12, and 13 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. 9E View Fig ) 1.1× as wide as long; lateral margins excavated at base, forming a triangular projection and then converging to rounded apex. Valve ( Fig. 9F View Fig ) 1.6× as wide as long; posterior margin rounded. Pygofer ( Fig. 9G View Fig ), in lateral view, 2× as long as maximum height; ventral margin broadly rounded; posterodorsal margin approximately straight; external surface near ventral margin with short filiform setae; macrosetae distributed on posterodorsal quadrant; apex slightly tapered and almost truncate. Subgenital plate ( Fig. 9G View Fig ), in lateral view, surpassing half length of pygofer; in ventral view ( Fig. 9H View Fig ), 4× as long as wide; lateral margins slightly rounded; ventral surface and external margin with long filiform setae; apex tapered and weakly sclerotized. Connective ( Fig. 9I View Fig ) T-shaped; arms weakly produced laterally; stalk narrow, slightly shorter than maximum width or arms; median keel weakly developed. Style ( Fig. 9J View Fig ), in dorsal view, with outer lobe well developed, rounded; in lateral view ( Fig. 9K View Fig ), blade slender, evenly curved dorsally, slightly broadened subapically; ventral margin not serrated; apex tapered, curved dorsally and acute. Aedeagus ( Fig. 9L–M View Fig ) preatrium not developed; dorsal apodeme weakly produced laterally, dorsal margin straight; shaft long and slender, cylindrical, curved anterad; pair of long and slender processes arising from basal third, parallel to shaft and slightly surpassing apex, enlarged at midlength and thin and acute apically; shaft without apical or subapical processes.
Female
Unknown.
Remarks
Costanana rubromarginata sp. nov. is similar to C. helvacosta , C. nana and C. santana in having the aedeagus with the shaft long and slender, with the pair of processes arising near the base of the shaft and without processes distally ( Fig. 9L–M View Fig ). The shape of the apex of the style, slightly expanded subapically ( Fig. 9K View Fig ), is most similar to that of C. nana , but the new species is separated in having the pair of lateral processes abruptly expanded medially and not parallel to the shaft along the entire length as in C. nana .
