Enochletica simulata Gorochov , sp. n.

( Figs 29–33 )

Material. Holotype, ♂ ( ZIN): Uganda, western region, Karabole Distr., environs of Kibale National Park , ~ 1500 m, secondary forest, at light, 6– 11.03.2020 (A. V. Gorochov) . Paratype: 1♂ ( ZIN), same data as for holotype .

Description. Male (holotype). Body colouration ( Fig. 29 ) very similar to that of E. ostentatrix Karsch, 1896 from Cameroon: head yellowish with brown genae as well as areas between antennal cavities and lateral parts of clypeus, two light brownish rose short median longitudinal stripes on dorsum, dark brown to brown middle and distal parts of antennal flagellum, dark brown (almost blackish) palpi, light brown rest of mouthparts (but with darker dorsal marks on clypeus and labrum) and rather numerous small spots on rest of antenna; pronotum reddish brown with brownish rose disc having a pair of yellowish stripes along lateral edges and three barely distinct lightish longitudinal lines between them; tegmina light brown to almost yellowish with brown, light brown, reddish brown and greyish spots ( Figs 29–31 ); hind wing darkened (almost dark grey) but with short yellowish subapical and small light brown to brown apical parts ( Fig.29 ); legs reddish brown with barely darker fore tibia, light brown fore and middle tarsi (having dark brown marks), and almost completely dark brown hind tarsus (but ventral parts of three proximal segments of all tarsi light); rest of thorax from greyish brown dorsally to reddish brown laterally and ventrally; abdomen dark brown with brown dorsum of anterior tergites, reddish brown sternites (having darker spots), and reddish brown to light brown small areas near these sternites as well as most part of cercus (but its distal part slightly darker) and proximal half of genital plate ( Fig. 32 ). External structure of body distinguished from that of E. ostentatrix only by stridulatory vein of left tegmen with clearly denser stridulatory teeth ventrally (1 mm of this vein in its middle part with 28 teeth; Fig. 33 ), and genital plate with wider apical part having shorter styles and posteromedian notch (width of this apical part ~1.3 times as great as length of each style; Fig. 32 ); genitalia membranous.

Variability. Paratype with barely wider distal part of mirror in both tegmina and slightly narrower apical part of genital plate (width of this apical part ~1.1 times as great as length of each style) as well as even less deep posteromedian notch of genital plate, and without reddish or rose tinge on all body parts.

Female unknown.

Length (in mm). Body 18–20; body with wings 43–44; pronotum 7.5–8; tegmina 37–38; hind femora 13.5–14.

Comparison. ffle new species is almost indistinguishable from E. ostentatrix (previously the only representative of this genus [ Massa, 2013]) in general appearance but with distinctly denser stridulatory teeth of the left tegmen (1 mm of the middle part of stridulatory vein has about 28 teeth in E. simulata sp. n. and about 17 teeth in E. ostentatrix ; compare Figs 33 and 35 ) as well as a wider apical part of the male genital plate and shorter styles (width of this apical part is about 1.1–1.3 times as great as length of each style in E. simulata sp. n., but this ratio is about 0.6–0.7 in Е. ostentatrix ; see Figs 32 and 34 ).

Etymology. fflis species name is the Latin word “simulata” (simulating, imitating) due to the similarity of the new species with E. ostentatrix .
