Antennal segment I with 10 setae, antennal segment II with 12 setae. Antennae III and IV fused dorsally and separated ventrally. Antennal segment III organ composed of two small, subcylindrical internal sensilla, two long subcylindrical guard sensilla and two guard setae between them; ventral microsensillum present. Antennal segment IV with trilobed apical vesicle, dorsoexternal microsensillum and 7 subcylindrical sensilla (e1–3, d1–2, i1, i1’) (as in Figs 3-4in Weiner & Kaprus’ (2005). Postantennal organ absent. Ocelli 4 + 4 with 4–5 ocular setae between them ( Fig. 6). Buccal cone elongated. Mandible with 6 teeth (including two strong basal teeth, two central denticles and two medium apical teeth). Maxilla styliform with two pointed lamellae ( Fig. 8). Labral chaetotaxy: 2/222. Labium without seta L as in Fig. 5in Weiner & Kaprus’ (2005). Dorsal chaetotaxy as in Figs 2–6. Setae very short, body sensilla (s) distinctly longer. Sensillar formula per half tergum: 022/11111. Head without setae a0 and with two setae d0. Thoracic tergum I with 4–6 + 4–6 setae. Thoracic terga II–III without setae a2. Microsensilla on thoracic tergum II present. Thoracic sterna without setae. Ventral tube with 6–7 + 6–7 setae. Furca absent. 5–6 microchaetae in furcal area ( Fig. 7). Each anal valve with two setae hr. Tibiotarsi I, II and III with 18, 18 and 17 setae, respectively (seta M absent, seta B7 absent on tibiotarsus III). Femora I, II and III with 12–13, 13 and 10–11 setae, trochanters I, II and III with 5–6, 5–6, 5–6 setae, coxae I, II and III with 2–3, 6–7 and 7 setae, subcoxae “2” I, II and III with 0, 2 and 2 setae, subcoxae “1” I, II and III with 4– 5, 5 and 5 setae, respectively.

Remarks. I. persica sp. nov.differs from I. poliakovaein large mandibles with two strong basal teeth, two central denticles and two medium apical teeth (versus small mandibles with 6 teeth in which 4 denticles) and many chaetotactic features e.g.: 4–5 ocular setae (versus 7),5–6 microchaetae in furcal area (versus 8), ventral tube with 6–7 + 6–7 setae (versus 9–10 + 9–10), subcoxae “1” I, II and III with 4–5, 5 and 5 setae respectively (versus 6, 7, 7).
