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

( Fig. 13 )

Diagnosis. Body coloration ( Fig. 13A, B ) mostly dark brown and black, brochosome coverage can give a bluish appearance on some parts of the body; head ( Fig. 13A, B ) almost completely dark brown to black, except for the tip of the anterior part of the head, which is castaneous brown; pronotum ( Fig. 13A ) black in anterior half and dark brown posteriorly; male forewing ( Fig. 13A, B ) completely black. Crown with anterior margin ( Fig. 13A ) broadly rounded; anterior portion ( Fig. 13B ), in lateral view, inflated; disk with a distinct depression; M-shaped elevation bordering posterior margin present and conspicuous. Connective ( Fig. 13E ) with arms converging anteriorly; base of arms with a U-shaped dorsal rim. Style ( Fig. 13E ) with apodeme wide and long, as long as apophysis; inner lobe rounded; apical portion almost as long as wide; not extending to connective apex. Aedeagal shaft ( Fig. 13F–H ) with anterodorsal projections slender and long. Dorsal connective ( Fig. 13F–H ) sclerotized; submedian acute process conspicuous.

Description. Total length: male (n = 1) 16.7 mm.

External structures. Crown ( Fig. 13A ) with anterior margin broadly rounded; in lateral view, anterior portion ( Fig. 13B ) inflated, forming an obtuse angle with frons. Ocelli located slightly behind an imaginary line between anterior eye angles. Hind legs with femoral setal formula 2:0:0 or 2:1:0. Other characters as in A. confusa sp. nov.

Coloration. Body coloration ( Fig. 13A, B ) mostly dark brown and black. Head ( Fig. 13A, B ) almost completely dark brown to black, except for the tip of the anterior part, which is castaneous brown. Pronotum ( Fig. 13A ) black on anterior half and dark brown posteriorly, as well as mesonotum ( Fig. 13A ). Thorax ( Fig. 13B ), in lateral view, with pleurites mostly dark brown to black, with some yellow areas; anepisternum ( Fig. 13B ) dark brown to black. Forewing ( Fig. 13A, B ) black. Legs ( Fig. 13B ) mostly dark brown to black, with some yellow areas mostly on articulations. Abdomen dark brown to black, with yellow areas along posterolateral margins of pleurites and on posterior margins of sternites.

Male terminalia. Pygofer ( Fig. 13C ) with ventral margin, in lateral view, regularly convex medially; preapical region with a small ventral concavity. Style ( Fig. 13E ) with apodeme wide and as long as apophysis. Other characters as in A. confusa sp. nov.

Female. Unknown.

Distribution. Peru (Madre de Dios department) ( Fig. 30 ).

Material examined. Type material: Holotype, ♂: PERU: Madre de Dios: Tambopata Res. Zone, Tambopata Research Center on Rio Tambopata , S13 08.305, W69 36.502, 622 ft, 3–7.x.2004, C. R. Bartlett ( MUSM).

Etymology. The specific epithet ‘ inornata ’ comes from the Latin and means “without ornaments or decorations”. This name is given because of the dark coloration of this species, lacking any striking bright or maculate coloration. It should be treated as an adjective.

Remarks. This species is somewhat similar to the males of A. horvathi s.s. ( Fig. 27A, B ), especially by the black coloration of the forewings and by the aspect of the crown in lateral view, which is inflated in the anterior part, a unique character shared only by these two species within Abana ( Figs. 13B , 27B ). The male genitalia are also almost identical to those of A. horvathi s.s. and A. amazonica sp. nov. ( Figs. 13C–H , 24C–H , 27C–H ); they differ only in the shape of the inner lobe of the style, which is rounded in A. inornata sp. nov. ( Fig. 13E ) and subtriangular in A. amazonica sp. nov. and A. horvathi s.s. ( Figs. 24E , 27E ). This makes it very difficult to distinguish these three species on the basis of the male genitalia alone. However, A. inornata sp. nov. has an almost completely dark brown to black coloration, with the exception of some small yellow areas on the thoracic and abdominal pleurites, on the legs near the articulation points, and on the posterior part of the abdominal sternites. Abana gigas also has a general brown coloration, but this is castaneous brown and clearly differs from the dark brown to black coloration of A. inornata sp. nov. These two species can also be easily distinguished by the morphology of the aedeagus, with the anterior dorsal processes of the shaft apex being slender and long in A. inornata sp. nov. (broad and short in A. gigas , Fig. 10I–K ). No COI sequence was obtained for this species.
