(Figs. 3D; 4D, M; 5D, M; 6D, M; 7D, J; 9 A, G; 10D, M; 11D, L; 12D, M)

Material studied. 10 L3 reared ex adults collected at: Greece, Thessaly, Mount Ossa, village Stomio, N°39.867, E°22.733, on Rubus sanctus at beach, 13.–20.vi.2007, H. Podskalská, P. Šípek lgt.; 18 L3 reared ex adults collected at: Greece, Stomio, Beach, at sea level, N°39.8761111, E°22.7313889, 16.–17.v.2015, O. Kouklík, D. Král, P. Šípek, D. Vondráček lgt.

Body length 17–21 mm. Cranium: width 2.89–3.04 mm, height 1.57–2.1 mm. Cranium brown with faint sculpture; elongate in shape, with its dorsal margin more or less convex at its entire length (length of dorsal straight portion of cranial margin less than ¼ of maximum width of cranium). Chaetotaxy as in Table 1. Epipharynx: Zygum with 11–15 stout conical setae and 10–14 similarly shaped setae at its proximal base. Chaetoparia with 56– 80 and 30–54 setae on right and left side respectively. Acanthoparia with 6–8 falcate setae. Stridulatory area of mandibles with 10–17 transverse ridges, ridges in apical third only slightly narrower than remaining ridges. Apical scissorial tooth of left mandible falcate, about twice the size of subapical one. Transverse proximal row of setae and sensilla on ligula composed of 10–11 stout lanceolate setae and campaniform sensilla combined. Setae of thoracic legs stout,short to long, or slender hair-like. Respiratory plate of spiracle with 18–20 holes across diameter. Raster polystichous, with 24–30 pali on each side, septula elliptic more than three times longer than wide. Tegillar setae variable in size from half of length of palus to four times as long as palus (longer setae quite frequent). Tegilla densely setose (average distance between two setae equals from one to two times length of palus), tegilla fused, campus absent. Dorsal parts of last abdominal segment densely setose, covered with numerous medium long and long setae, without ring of prominent long setae or circular field with conspicuously shortened setae.
