Figs 4– 5 , 11E–F

Diagnosis

Coloration ( Fig. 11E ) of crown black, pronotum brown with inconspicuous black maculae, forewing costal margin with sequence of small yellow spots and a small depigmented (white) macula on apical third. Style ( Fig. 4K ) without dentiform ventral process near base of blade; apical third with short slender process overlapping dorsal apex. Aedeagus ( Fig. 4L–M ) without processes near base; shaft with short subapical spiniform process on dorsal margin and pair of long subapical processes almost as long as shaft length, directed dorsally and curved anterad.

Etymology

The new species name is an anagram of the initials C.I.I.F. and refers to the Centro de Identificação de Insetos Fitófagos, Departamento de Zoologia of Universidade Federal do Paraná, that sampled many insects in Paraná State in the year 1985.

Description

MEASUREMENTS. Holotype male: total length 5.2 mm. Paratype female (n = 2) 5.6–5.8 mm.

COLORATION. Dorsal portion of head and thorax reddish-brown ( Figs 4A, C , 11E ); ventral portion yellow ( Figs 4B–C , 11F ). Crown ( Fig. 4A ) black; eyes and ocelli red. Pronotum ( Fig. 4A ) with inconspicuous irregular black maculae near anterior margin; lateral margin yellow. Mesonotum with small yellowish spots near anterior margin and scutoscutellar suture. Face ( Fig. 4B ) with frons almost completely black, except with lateral and ventral margins brownish; gena black between eye and frons. Forewing ( Fig. 4D ) costal margin with small slender yellow macula on anterior fifth, sequence of 13–14 yellow spots and a small depigmented (white) macula at apex of outer apical cell; veins brown with several yellowish spots. Legs ( Figs 4C , 11F ) yellow, without black markings.

STRUCTURE. Head in dorsal view ( Fig. 4A ): median length slightly shorter than interocular width; transocular width of head 8.5 tenths humeral width of pronotum; in lateral view ( Fig. 4C ), with anterior margin thick, with 7–8 well developed carinae. Forewing ( Fig. 4D ) with inner discal cell not distinctly shorter than outer discal cell; apex rounded. Profemur AV row with 3–4 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 6–7 setae increasing in thickness and length towards apex. Metatibia rows PD, AD, and AV with 18–19, 12, and 13–14 macrosetae, respectively. Metatarsomere I apex with 3–4 platellae. Metatarsomere II apex with 2 apical platellae. Other characteristics as in the generic description.

MALE TERMINALIA. Sternite VIII ( Fig. 4E ) 1.2× as wide as long; lateral margins excavated at base, forming a triangular projection; apex broadly rounded. Valve ( Fig. 4F ) 2× as wide as long; posterior margin rounded, slightly emarginated medially. Pygofer ( Fig. 4G ), in lateral view, 2.2× as long as maximum height; ventral margin slightly rounded; posterodorsal margin rounded; posteroventral margin straight; external surface near ventral margin with short filiform setae; macrosetae distributed on apical half; apex subtruncated. Subgenital plate ( Fig. 4G ), in lateral view, short, slightly surpassing half length of pygofer; in ventral view ( Fig. 4H ), 4.5× as long as wide; inner margin straight; external margin broadly rounded; ventral surface and external margin with long filiform setae; apex tapered and weakly sclerotized. Connective ( Fig. 4I ) Y-shaped; arms weakly produced laterally; stalk narrow, about as long as maximum width of arms; median keel weakly developed. Style ( Fig. 4J ), in dorsal view, with outer lobe reduced; in lateral view ( Fig. 4K ), blade strongly elongated, almost straight; ventral margin not serrated, with short slender process at apical third, directed posterad, weakly curved dorsally and overlapping dorsal apex; apex tapered and curved dorsally. Aedeagus ( Fig. 4L–M ) preatrium developed; dorsal apodeme strongly produced, with divergent arms; shaft elongated curved dorsally; dorsal margin with subapical spiniform process; pair of long subapical processes almost as long as shaft length, directed dorsally and curved anterad, with apex tapered and sharply acute.

FEMALE TERMINALIA. Sternite VII ( Fig. 5A, C ), in ventral view, 2.4× as wide as long; posterolateral angles rounded and weakly produced posterad; posterior margin almost straight and slightly excavated medially. Internal sternite VIII membranous. Pygofer ( Fig. 5A–B ), in lateral view, approximately 2× as long as high; macrosetae distributed on posteroventral quadrant; apex rounded. First valvifer ( Fig. 5D ) subelliptic, slightly higher than wide. First valvula ( Fig. 5D ) 10× as long as high; ventral interlocking device long, reaching apical fifth; dorsal sculptured area areolate; apical portion ( Fig. 5E ) gradually tapering to apex; apex acute and areolate. Second valvula ( Fig. 5F ) 10.5× as long as high; dorsal protuberance reduced and acute, localized before midlength of blade; apical portion ( Fig. 5G ) of dorsal margin with a larger tooth followed by small denticles, approximately regular in shape and size; ventroapical margin with minute rounded denticles; apex rounded. Second valvifer ( Fig. 5H ), in lateral view, approximately 2.5× as high as wide. Gonoplac ( Fig. 5H ) 5.4× as long as high; dorsoapical margin straight, longer than one-third of gonoplac length; ventral margin evenly rounded, with a few short setae; outer surface ( Fig. 5I ) with many integumentary denticles; rounded apex.

Remarks

Costanana cifi sp. nov. is similar in coloration to C. nupera comb. nov. in having the costal margin of the forewing with a small and slender yellow macula on the anterior fifth followed by a sequence of small yellowish spots and a larger white macula at the apex of the outer apical cell ( Figs 4D , 20A ). Costanana cifi can be separated from the other species of Costanana by the unusual shape of the aedeagus, with a short subapical spiniform process on the dorsal margin and a pair of long subapical processes directed dorsally and curved anterad ( Fig. 4L ).
