Diagnosis

Coloration ( Fig. 12C View Fig ) of head and pronotum dark brown with black maculae, forewing costal margin with broad light yellow macula on anterior third and large depigmented (white) macula on apical third. Style ( Fig. 8K View Fig ) with ventral dentiform process near base of blade; apex abruptly tapered and acute. Aedeagus ( Fig. 8L–M View Fig ) without processes near base; shaft moderately slender, with pair of long filiform subapical processes directed basally, almost as long as shaft length; apex weakly compressed, subacute.

Etymology

The new species name refers to the municipality of Piraquara, where the holotype was collected.

Description

Male

MEASUREMENTS. Holotype male: total length 6.9 mm.

COLORATION. Dorsal portion of head and thorax brown ( Figs 8A, C View Fig , 12C View Fig ); ventral portion yellow ( Figs 8B–C View Fig , 12D View Fig ). Crown ( Fig. 8A View Fig ) reddish-brown; transverse black stripe interrupted medially over median line; pair of rounded black spots behind ocelli, near posterior margin; eyes and ocelli red. Pronotum ( Fig. 8A View Fig ) dark brown; black irregular maculae and reddish-brown areas near anterior margin; lateral margin yellow. Mesonotum lateral angles dark brown. Face ( Fig. 8B View Fig ) with frons brownish, dorsal portion black, short black stripes over muscle impressions; gena black between eye and frons. Forewing ( Fig. 8D View Fig ) with large triangular light yellow macula on anterior third of costal margin and large rounded depigmented (white) macula at level of outer anteapical cell; remaining portion of costal cell, apical cells, apex of clavus and appendix dark brown; apical margin whitish. Legs ( Fig. 12D View Fig ) yellow; apex of metatibia dark brown.

STRUCTURE. Head in dorsal view ( Fig. 8A View Fig ): median length of crown slightly shorter than interocular width; transocular width of head eight tenths humeral width of pronotum; in lateral view ( Fig. 8C View Fig ), with anterior margin thick, with 5–6 well developed carinae. Forewing ( Fig. 8D View Fig ) inner discal cell open, m-cu 2 crossvein absent; apex broadly rounded. Profemur AV row with 3–4 setae restricted to basal half and PV row with 1 apical seta. Protibia PD row with 4 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 24–25, 14, and 15 macrosetae, respectively. Metatarsomere I apex with 4 platellae. Metatarsomere II apex with 2 apical platellae. Other characteristics as in the generic description.

MALE TERMINALIA. Sternite VIII ( Fig. 8E 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. 8F View Fig ) 2.7× as wide as long; posterior margin almost straight. Pygofer ( Fig. 8G View Fig ), in lateral view, 1.8× as long as maximum height; basodorsal process present but weakly developed; ventral margin with rounded protrusion near basal third; posterodorsal and ventral margins straight; external surface near ventral margin with short filiform setae; macrosetae distributed on posterodorsal quadrant; apex broad and truncate. Subgenital plate ( Fig. 8G View Fig ), in lateral view, slightly surpassing half length of pygofer; in ventral view ( Fig. 8H View Fig ), 3.2× as long as wide; inner margin straight; external margin slightly rounded; ventral surface and external margin with long filiform setae; apex tapered and weakly sclerotized. Connective ( Fig. 8I View Fig ) linear; arms not produced laterally; stalk very broad, slightly longer than maximum width of arms; median keel weakly developed. Style ( Fig. 8J View Fig ), in dorsal view, with outer lobe reduced and rounded; in lateral view ( Fig. 8K View Fig ), blade broadened medially; ventral margin not serrated, with dentiform process near base of blade; apex abruptly tapered, slightly directed dorsally, acute. Aedeagus ( Fig. 8L–M View Fig ) preatrium not developed; dorsal apodeme elongated laterally, forming divergent and truncated apices; shaft slender, curved dorsally; pair of long subapical filiform processes directed basally, almost as long as shaft length; apex compressed, subacute.

Female

Unknown.

Remarks

Costanana piraquarensis sp. nov. is separated from C. obtusa sp. nov. in having the following differences: (1) apex of pygofer truncated ( Fig. 8G View Fig ); (2) connective shorter ( Fig. 8I View Fig ); (3) style with apex acute ( Fig. 8K View Fig ); (4) aedeagal shaft wider ( Fig. 8L–M View Fig ); and (5) subapical pair of processes lacking spurs near base ( Fig. 8M View Fig ).
