( Figs. 3B ; 4B, K ; 5B, K ; 6B, K ; 7B, H ; 8E, K ; 10B, K ; 11B, J ; 12B, K )

Material studied. 4 L3 reared ex adults collected at: Macedonia, Negotino env., 2 km S from Pepelishte, N°41.546, E°22.139, semi-arid hills and continental steppe habitats 12.–13.vi.2014, P. Šípek lgt.; 19 L3 reared ex adults collected at: Macedonia, Negotino env., N of Pepelishte, ca 120–170 m, N°41.53694, E°22.13833, 19.v.2015, O. Kouklík, D. Král, P. Šípek, D. Vondráček lgt.

Body length 15–18 mm. Cranium: width 2.01–2.21 mm, height 1.18–1.38 mm. Cranium yellowish to yellowish-brown, smooth; semi-circular in shape, dorsally flattened (length of dorsal straight portion of cranial margin slightly less than one half of maximum width of cranium). Chaetotaxy as in Table 1. Epipharynx: Zygum with 10–13 stout conical setae and 5–7 similarly shaped setae at its proximal base. Chaetoparia with 45–52 and 30– 36 setae on right and left side, respectively. Acanthoparia with 4–6 ovate setae, 1 or 2 distal setae elongated. Stridulatory area of mandibles with 9–11 evenly broad transverse ridges. Apical scissorial tooth of left mandible falcate, about two times larger than subapical tooth. Transverse proximal row of setae and sensilla on ligula composed of approximately 10 stout lanceolate setae and campaniform sensilla combined. Thoracic legs with stout (spine-like) or long hair-like setae, the hair-like setae are well developed prominent, never slender. Respiratory plate of spiracle with 11–13 holes across diameter. Raster monostichous composed of single horseshoe-like row of 19–26 pali, septula broadly ovate, opened posteriorly, almost as wide as long. Tegillar setae about size of pali or three times as long, few longer setae present as well. Tegilla fused, only sparsely setose (average distance between two setae about three times of length of palus), campus absent. Dorsal parts of last abdominal segment with circular row of long setae surrounding field of short ovate setae.
