Steleops furcatus sp. nov.

( Figs 214–221 )

Diagnosis. Belonging to the group mendivili . It differs from S. mendivili and S. clavatus sp. nov., for presenting the hypandrium with apically forked arms in the shape of a “C” and with the medial band densely covered with long papillae ( Fig. 220 ).

Male. Color (in plate and 80% ethanol). Head ( Fig. 216 ) light cream, with Y-shaped spot from base of compound eyes and vertex to postclypeus. Ochre compound eyes. Forewings ( Fig. 214 ) hyalines, pterostigma light brown, veins brown. Hindwings ( Fig. 215 ) hyalines, veins brown. Terminalia abdominal brown, clunium pale brown, clunium arm pale brown, apically darker, epiproct and paraprocts light cream. Legs yellowish.

Morphology. As in diagnosis, plus the following: Head ( Fig. 216 ): H/MxW: 1.11; compound eyes large, pedunculated, H/D: 2.05; IO/MxW: 0.70. Vertex V–shaped wide, below upper level of compound eyes. Outer cusp of lacinial tips with four denticles; Mx4/Mx2: 0.95. Forewings ( Fig. 214 ): L/W: 2.94. Pterostigma: lp/wp: 2.18, areola postica: al/ah: 3.31. Hindwings ( Fig. 215 ): l/w: 3.03. Clunium ( Fig. 219 ) with lateral arms on each side of the paraprocts, apically forked, C-shaped. Hypandrium ( Fig. 220 ) symmetrical, with tongue-shaped medial band, distally bilobed and covered superficially by numerous long finger-like papillae and spicules on the proximal dorsal surface, with arms of the hypandrium fused apically with the medial band. Phallosome symmetrical, rhomboid ( Fig. 221 ), aedeagus apically bilobed, with 4-6 lateroapical teeth, elongated and lateral parameres, pallobase elongated anteriorly, basally narrow, and truncated. Epiproct ( Fig. 217 ) subtriangular, distally more widened, with macrosetae and setae, posterior margin angled, anteriorly projecting onto clunium, with microspicules and setae as illustrated. Paraprocts ( Fig. 218 ) with setose medial tubercle and long, curved, distally acuminate lateroapical process, sensory fields with 31 trichobothria on basal rosettes.
