Distinctly convex, surface brownish or light-brown, shiny, pronotum covered with double punctation, elytron very fine microsculptured basally, microsculture missing apically. Head ( Figs 5 , 18 , 25 , 31 , 37 , 57 ). Clypeus broadly rounded, nearly semicircular, anterior angles vague. Posterior angles of clypeal margin elevated. Frontal horn well developed, long, distinctly furcate, base triangularly shaped in dorsal view, posterior edge of base situated at height of center of eye, side margin of tubercle keeled from base to apex. Punctation of clypeal disc simple, distinct. Oblique keels above eyes reaching approximately to half of eyes. Punctation of frons and vertex same as on clypeus; frontoclypeal suture present. Eyes distinctly elliptic and well developed; genae arcuate posteriorly, extending eyes laterally. Pronotum ( Figs 5 , 18 , 25 , 31 , 37 , 57 ) distinctly transverse; broadest just in basal quarter, entirely bordered; lateral margin evenly rounded, marginal carina not crenate, distinctly widened and elevated; lateral fovea almost missing. Pronotal punctation distinct, double, consisting of deeply impressed punctures, punctures separated by approximately 2–3 times their diameter, intermixed with very fine, pinned punctures. Base of pronotum glabrous. Lateral hornlike apophyses well developed, bent distinctly upwards and sidewards in lateral and dorsal view; between lateral and apical apophyses distinct, deeply oval concavity.Apical hornlike apophyses distinctly elevated, angled, directed 30° frontoapically, subapical protrusion of apical apophyses laterally near apex on outside. Scutellar shield triangular elongate, very finely punctate, shiny. Elytra approximately as long as wide, surface shiny, glabrous; between suture and humerus 7 distinct striae along entire elytral length, all striae with distinctly separated punctures; intervals flat; humeral umbone weak. Parameres as in Fig. 64 . Variability in males. Surface black to brownish; pronotal hornlike apophyses in medium developed and underdeveloped (hypothelic) specimens short, more or less straight, only simply rounded to almost acute apically. Female ( allotype ) . Head ( Figs 12 , 43 ). Clypeus broadly rounded, semicircular with straight anterior margin, anterior angles evenly rounded. Posterior angles of clypeal margin very weakly elevated. Frontal carina well developed, distinctly interrupted in middle, bituberculate on internal interruption, laterally keeled on each side. Punctation of clypeus, frons, vertex and occiput simple, distinct; oblique keels above eyes distinct, elongated to half of eyes; eye well developed, distinctly elliptic, genae well developed, arcuate anteriorly and posteriorly. Pronotum ( Fig. 12 ) distinctly transverse, lateral margin weakly widened, broadest just basally, surface distinctly deeply punctate, double except of basal part, punctures consisting of well and deeply impressed punctures, separated approximately by distance equal to their diameter, intermixed with very fine, pinned punctures.Anterior transverse protrusion distinct, sharply semicircular, lateral apophyses present. Elytron surface shiny, glabrous; humeral umbone weak. Measurements. Total body length 12.0–15.1 mm ( holotype , ♂: 14.6 mm; allotype , ♀ : 14.8 mm). Differential diagnosis. Refer to species key. Etymology. Patronymic; named in honour of our friend Georgy V. Nikolajev (Al-Farabi State University, Almaty , Kazakhstan ), a renowned specialist in world Scarabaeoidea. Collection circumstances. Prefers sandy and/or loess soils. Distribution. Mediterranean Egypt , Libya (Tripolitania, Cyrenaica) and Tunisia (Fig. 59).
