Steleops taurus, González-Obando & Calderón-Martínez & Carrejo-Gironza & Manchola, 2025

Steleops taurus sp. nov.

( Figs 222–228 View FIGURES 222–228 )

Diagnosis. It forms a unique morphological group. It differs from all Steleops species by having phallosome with calf's head shaped ( Fig. 228 View FIGURES 222–228 ), aedeagus represented by two lobular processes articulated to a membranous structure, parameres as lobular processes slightly curved outwards, widely separated and apically with tiny spines. Hypandrium with three basal acuminate processes, the two lateral ones larger, also with a pair of anteromedial globular structures with a rounded apex ( Fig. 227 View FIGURES 222–228 ).

Male. Color (in plate). Head ( Fig. 224 View FIGURES 222–228 ) dark brown, genae and lateral areas of the labrum light cream. Compound eyes light, with some brown ommatidia. Forewings ( Fig. 222 View FIGURES 222–228 ) hyalines, with some brown spots and brown veins. Hindwings ( Fig. 223 View FIGURES 222–228 ) hyalines, veins brown. Epiproct light brown, paraprocts brown. Hypandrium brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 224 View FIGURES 222–228 ): H/MxW: 1.10; compound eyes large, elongated, H/D: 2.33; IO/MxW: 0.31. Vertex V–shaped wide, below upper level of compound eyes. Outer cusp of lacinial tips with four denticles; Mx4/Mx2: 1.27. Forewings ( Fig. 222 View FIGURES 222–228 ): L/W: 2.80. Pterostigma: lp/wp: 2.90, areola postica: al/ah: 0.20. Hindwings ( Fig. 223 View FIGURES 222–228 ): l/w: 0.44. Hypandrium asymmetric, with three basal acuminate processes, also with a pair of anteromedial lobular structures with a rounded apex ( Fig. 227 View FIGURES 222–228 ). Phallosome with calf's head shaped ( Fig. 228 View FIGURES 222–228 ), aedeagus represented by two lobular processes articulated to a membranous structure, parameres as lobular processes slightly curved outwards, widely separated and apically with tiny spines ( Fig. 228 View FIGURES 222–228 ). Epiproct ( Fig. 225 View FIGURES 222–228 ) pyramid-shape, with rounded corners. Paraprocts ( Fig. 226 View FIGURES 222–228 ) oval, with apical process slightly curved at the base, shorter than the rest of the paraproct, distally acuminate and curved, sensory fields with 19-20 trichobothria on basal rosettes.
