Abana confusa Sauceda-V & Takiya, sp. nov.

( Fig. 6 View FIGURE 6 )

Diagnosis. Body coloration ( Fig. 6A, B View FIGURE 6 ) mostly orange and black; anterior portion of crown ( Fig. 6A View FIGURE 6 ) and dorsal portion of frons ( Fig. 6B View FIGURE 6 ) orange, crown with contrasting dark maculae posteriorly and frons with contrasting dark maculae inferiorly; pronotum ( Fig. 6A View FIGURE 6 ) dark brown to black, with two anterolateral orange maculae; male forewing ( Fig. 6A, B View FIGURE 6 ) dark brown, with two broad orange transverse transcommisural stripes: one at basal half and another preapical, aligned to clavus apex. Crown anterior margin ( Fig. 6A View FIGURE 6 ) subtriangular, apex truncate; anterior portion ( Fig. 6B View FIGURE 6 ), in lateral view, straight, not inflated; disk with a distinct depression; M-shaped elevation bordering posterior margin present and conspicuous. Connective ( Fig. 6E View FIGURE 6 ) arms parallel; base of arms with a U-shaped dorsal rim. Style ( Fig. 6E View FIGURE 6 ) with apodeme wide and long, 0.8 times as long as apophysis length; inner lobe rounded; apical portion almost as long as wide; not extending to connective apex. Aedeagal shaft ( Fig. 6F–H View FIGURE 6 ) with anterodorsal projections slender and long. Dorsal connective ( Fig. 6F–H View FIGURE 6 ) sclerotized; submedian acute process conspicuous.

Description. Total length: male (n = 1) 16.9 mm.

External structures. Crown ( Fig. 6A View FIGURE 6 ) without pubescence; anterior margin subtriangular, apex truncate; in lateral view, anterior portion ( Fig. 6B View FIGURE 6 ), straight, not inflated, forming an acute angle with frons; disk with a distinct depression; posterior margin M-shaped elevation present and conspicuous. Ocelli located on imaginary line between anterior eye angles; each slightly closer to adjacent anterior eye angle than to midline. Frons evenly convex medially. Pronotum ( Fig. 6A View FIGURE 6 ) surface without pubescence. Forewing ( Fig. 6A, B View FIGURE 6 ) with punctures distributed throughout membrane; base of fourth apical cell slightly more distal than base of third apical cell. Hind legs with femoral setal formula 2:0:0. Other characters as in generic description.

Coloration. Body coloration ( Fig. 6A, B View FIGURE 6 ) mostly orange and black. Crown orange, except for a black macula on posterior portion between antennal ledges, indented medially, divided into two subquadrate areas. Frons ( Fig. 6B View FIGURE 6 ) with upper two thirds also orange, ventral third black as well as clypeus and gena, continuing black area of crown. Pronotum ( Fig. 6A View FIGURE 6 ) dark brown to black, with two anterolateral orange maculae continuing laterally to proepimeron. Mesonotum ( Fig. 6A View FIGURE 6 ) black. Thorax ( Fig. 6B View FIGURE 6 ), in lateral view, with pleurites mostly orange, with small black areas; anepisternum ( Fig. 6B View FIGURE 6 ) black. Forewing ( Fig. 6A, B View FIGURE 6 ) dark brown, lighter at apex, with two broad orange transverse transcommissural stripes: one at basal half, broader at clavus, reaching costal margin and another broader at corium, reaching costal margin, aligned to clavus apex. Legs ( Fig. 6B View FIGURE 6 ) almost completely orange, with some brown to black small portions mostly at apex of tibiae and tarsomeres of all legs.

Male terminalia. Pygofer ( Fig. 6C View FIGURE 6 ) ventral margin, in lateral view, regularly convex until apex. Subgenital plates ( Fig. 6C View FIGURE 6 ), in lateral view, ending clearly before pygofer apex. Connective ( Fig. 6E View FIGURE 6 ) with arms converging anteriorly; base of arms with a U-shaped dorsal rim. Style ( Fig. 6E View FIGURE 6 ) with apodeme wide and long, 0.8 times as long as apophysis length; inner lobe rounded; angle formed between preapical lobe and apical portion acute; apical portion subquadrate, almost as long as wide; not extending to connective apex. Aedeagal shaft ( Fig. 6F View FIGURE 6 ), in lateral view, with preapical dorsal spiniform process extending to dorsal margin of lateral projections; anterodorsal projections ( Fig. 6F–H View FIGURE 6 ) slender and long. Dorsal connective ( Fig. 6F–H View FIGURE 6 ) sclerotized; submedian acute process conspicuous. Other characters as in generic description.

Female. Unknown

Distribution. Peru (Huánuco Region) ( Fig. 30 View FIGURE 30 ).

Material examined. Type material: Holotype, ♂: PERU: Huánuco: Monson Valley Tingo Maria, 1954-vi-29 ( NCSU).

Etymology. The specific epithet ‘ confusa ’ comes from Latin and is the perfect passive participle of the verb cônfundere, which means “confused”. It should be treated as an adjective. This name is given because the holotype is a male with a striped coloration similar to that of the females of the A. horvathi complex, which can lead to confusion during identification.

Remarks. This species is similar to A. minuta sp. nov. and to the species of the A. horvathi complex ( A. amazonica sp. nov., A. colombiana sp. nov., and A. horvathi s.s.), sharing characters of the external morphology and having the male genitalia almost identical. However, A. confusa sp. nov. can be distinguished from these four species by the color pattern of the forewings of males ( Fig. 6A, B View FIGURE 6 ), with two broad transverse stripes, resembling the color pattern of some females of A. colombiana sp. nov. and A. horvathi s.s. ( Figs. 26A–D View FIGURE 26 , 28A, B View FIGURE 28 , 29G–R View FIGURE 29 ). Males of A. haupti also display two light transverse stripes on the forewings ( Fig. 12A–B View FIGURE 12 ); nonetheless, A. confusa sp. nov. can be distinguished from the latter mostly by the morphology of the head, with the anterior margin of the crown subtriangular and truncate at the apex (rounded in A. haupti , Fig. 12A View FIGURE 12 ), and the body coloration, being mostly orange and black (mostly brown in A. haupti , Fig. 12A, B View FIGURE 12 ). No molecular information was obtained for this species because the only specimen was very old.
