Steleops clavatus sp. nov.

( Figs 207–213 )

Diagnosis. Belonging to the mendivili group, unlike Steleops mendivili and S. furcatus sp. nov., presents the arms of the clunium apically thickened ( Fig. 211 ), hypandrium with the medial band covered with pointed papillae ( Fig. 212 ), forewing with Rs-M veins fused in a short distance; phallosome more widened and with shorter phallobase than in S. furcatus ( Fig. 213 ). As in S. furcatus , it has a symmetrical hypandrium, but the medial band does not have elongated acuminate processes and the denticles are more elongated and densely distributed ( Fig. 212 ).

Male. Color (in plate and 80% ethanol). Head ( Fig. 209 ) cream yellow with brown spots on frons, postclypeus and ocellar tubercle. Compounds eyes dark ochre. Forewings ( Fig. 200 ) hyalines, pterostigma light brown, veins brown. Hindwings ( Fig. 208 ) hyalines with veins brown. Legs pale brown. Terminalia abdominal pale brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 209 ): H/MxW: 1.26; compound eyes large, pedunculated, almost rounded, H/D: 2.06; IO/MxW: 0.56. Vertex U–shaped wide, below upper level of compound eyes. Outer cusp of lacinial tips with three broad denticles; Mx4/Mx2: 1.20. Forewings ( Fig. 207 ): L/W: 3.18. Pterostigma widened medially: lp/wp: 3.88, areola postica: al/ah: 1.91. Hindwings ( Fig. 208 ): l/w: 3.29.Arms of the clunium on each side of the paraprocts, widened apically, club-shaped, covered with small spicules. Hypandrium symmetrical ( Fig. 212 ), with a tongue-shaped medial band, distally bilobed and with numerous elongated finger-like papillae and spicules on the proximal dorsal surface, with hypandrium arms fused apically with the medial band. Phallosome rhomboid symmetrical and widened ( Fig. 213 ), apically with aedeagus widened, parameres apparently lateral, phallobase short anteriorly, basally narrow. Epiproct ( Fig. 210 ) projected on the clunium, rhomboid, widened distally with angled posterior margin, proximally narrow and with setae and microsetae. Paraprocts somewhat oval ( Fig. 211 ), with setae as illustrated, with long, inwardly curved, lateroapical process; sensory fields with 24 trichobothria on basal rosettes.
