Weissenbornia praestantissima aurea

Gorochov, subsp. n.

( Figs 36–38 )

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).

Description. Male (holotype). General appearance ( Fig. 36 ) very similar to that of nominotypical subspecies, but body colouration with following differences: labrum yellowish rose, strongly widened part of maxillary palpus light brown, tegmina yellowish with mostly light brown pattern (vs labrum and widened part of maxillary palpus intensively brown, and tegminal pattern dark brown to blackish). External structure of body almost identical to that of W. p. praestantissima Karsch, 1888 but having some characteristic features: stridulatory vein of left tegmen with ventral teeth as in Fig. 37 (1 mm of middle part of this vein with 31 stridulatory teeth); abdominal apex ( Fig. 38 ) with straight (not slightly concave) posterodorsal edge of last tergite, somewhat more curved cerci, and clearly shorter posteromedian notch of genital plate (each style of latter plate approximately trice as long as this notch; in nominotypical subspecies, style almost twice as long as this notch); genitalia membranous.

Female unknown.

Length (in mm). Body 19; body with wings 38; pronotum 5.8; tegmina 30; hind femora 14.5.

Comparison. Differences between the new subspecies and E. p. praestantissima from Cameroon are listed above, in the description.

Etymology. fflis subspecies name is the Latin word “aurea” (golden) due to the characteristic body colouration.
