Platypona furcata sp. nov.

( Figs 1–12 , 24, 25 )

Diagnosis. Frons and dorsal portion of clypeus ( Fig. 2 ) dark brown to black; male pygofer ( Fig. 7 ) with ventrocaudal margin emarginate, forming two lobes; styles ( Figs 9, 10 ) forked near midlength; aedeagal shaft ( Figs 11, 12 ) without processes, but with serrated lateral flanges at apical half; processes of aedeagal dorsal apodemes without basodorsal projection.

Measurements (mm). Male holotype: total length 9.6; crown median length 1.0; transocular width 2.4; interocular width 1.4; pronotum median length 1.3; width between humeri 2.9; mesonotum median length 1.6; mesonotum maximum width 2.2; forewing length 7.0; forewing maximum width 2.0.

Color. Body ( Figs 24, 25 ) with ground color pale yellow. Crown ( Figs 1, 3 ) with pair of small spots on anterior margin in front of ocelli, thin longitudinal median stripe, and anterior margin, orange; pair of small irregular brown areas behind ocelli. Ocelli ( Figs 1, 3 ) red. Antennal ledges orange with black carina. Frons and dorsal portion of clypeus ( Fig. 2 ) dark brown to black. Pronotum ( Figs 1, 3 ) with small irregular brown areas distributed on anterior third and lateral areas, extending posteriorly to humeral angles. Mesonotum ( Figs 1, 3 ) with basal angles brown. Forewings ( Fig. 4 ) with basal 2/3 semi-hyaline and apical third hyaline; irregular oblique brown band extending from base of first apical cell to base of median anteapical cell; veins mostly pale yellow with some small darkened portions. Hind wings ( Fig. 5 ) with veins brownish-yellow to brown. Legs yellow ( Fig. 25 ); fore and middle legs with femoral apices and tibiae marked with orange; hind legs with femoral apices and parts of tibiae dark brown.

External morphology. Crown with oblique striae converging apically. Pronotum ( Fig. 1 ) with transverse striae on central portion of median third and on posterior third. Forewings ( Fig. 4 ) approximately 3.5 times longer than wide; venation distinct, without supernumerary veins; three closed anteapical cells, base of median anteapical cell slightly more proximal than bases of other ones; five apical cells (R1 present); apex rounded; appendix very narrow, extending from claval apex to second apical cell. Hind legs with plantar surface of first tarsomere with one row of very short setae.

Male terminalia. Sternite VIII ( Fig. 6 ) with maximum width about 4/5 of length; anterior margin slightly concave; lateral margins converging apically; posterior margin narrow, with shallow median concavity. Pygofer ( Fig. 7 ) lobe with ventrocaudal margin bilobed; inner surface with hook-shaped process arising dorsally, near base of anal tube, extending ventrocaudally but with apex directed caudally; disk with long robust setae on dorsoapical half and minute microsetae distributed along ventrocaudal margin; apex rounded. Valve ( Fig. 7 ) laterally fused to pygofer. Subgenital plates ( Figs 7, 8 ) elongate, 3.7 times longer than maximum width, not extending posteriorly as far as pygofer apex; outer margin with minute microsetae distributed at apical half; ventral surface with long setae on apical 4/5 close to outer margin; apex narrowly rounded. Connective ( Fig. 10 ) Y-shaped; arms broad and directed dorsally. Style ( Figs 9, 10 ) elongate; in lateral view, forked near midlength, forming strong, straight dorsal process with sclerotized hook-shaped apex; apical portion elongate and more slender than dorsal process, curved dorsally; apex acute. Aedeagus ( Figs 11, 12 ) with shaft tubular, basal third with short dorsal keel, laterally expanded preapically, with pair of lateral serrated flanges; dorsal apodemes with pair of slender elongate processes extending adjacent to ventral margin of shaft to its apex, where each is strongly bent basolaterally, forming falciform crossed apices of 1/5 length of shaft; preatrium absent; gonopore located at apex. Anal tube (segment X) without processes.

Female unknown.

Etymology. The new species name alludes to the male style, which is deeply forked ( Figs 9, 10 ).

Material examined. Male holotype: “ PERU: Cusco [Department], 3 rd km E Quincemil \ 13°13’03’’S 70°43’40’’W 633m \ 20.VIII-01.IX.2012, Malaise \ RR Cavichioli, JA Rafael, APM \ Santos & DM Takiya”, “ DNA voucher\ Entomologia, DZRJ \ ENT 1218” ( MUSM).

Notes. Platypona furcata sp. nov. can be easily distinguished from the other species of Platypona by the black coloration of face ( Fig. 2 ) and characters of the male genitalia. This new species has the following features: (1) styles ( Figs 9, 10 ) more robust with a long dorsal process near midlength (appearing deeply forked), while in P. sinverda and P. i n c a sp. nov. they are very slender and bifurcate more apically ( Figs 20, 21 ); (2) aedeagal shaft ( Figs 11, 12 ) with lateral serrated flanges at expanded portion and without processes, while P. sinverda and P. i n ca sp. nov. do not have lateral serrated flanges and have a pair of short apical processes ( Figs 22, 23 ); and (3) processes of the dorsal apodeme ( Fig. 11 ) without basodorsal projection, while P. sinverda and P. i n c a sp. nov. have a dorsal projection at basal third ( Fig. 22 , arrowed).
