In D. loricatus males, T 14 is the broadest, but without two lobes (Figs 22 & 26). In females, T 12 is of similar length and width, concave at the rear edge, without formed lobes (Farzalieva & Zalesskaja 2003: Fig. 10). The main differences between D. svenhedini and D. loricatus are summarized in Table 3. Description. See a detailed redescription by Farzalieva & Zalesskaja (2003). Remarks. The head and tergites are strongly punctate; the forcipules broadened, significantly extended beyond the cephalic plate (Fig. 23), the trochanteroprefemur is slightly concave on the inner surface, with an almost straight, ventral, chitinous rib (Fig. 24). All males have T 14 and Tim broadened and serrate, especially strongly broadened is T 14, their surface roughly rugose (Figs 22 & 26). In addition, some specimens show serrate edges of T 13 and slightly serrate posterolateral edges of T 12. In all males, 15F are thickened, with two distinct sulci, i.e. a poorly expressed dorsolateral sulcus and a deep dorsal sulcus, the latter forming apically a round tubercle supporting a cluster of thick and short setae; some specimens in addition with 1 or 2 poorly expressed dorsal sulci on 15P; 15Ti with a barely visible dorsolateral sulcus. In most males, very fine and dense setae cover rear halves of SS 14���15, as well as 14C, 13P, F and Ti ventrally. Tarsi 1���13 with two ventral tarsal pectens. Disphaerobius svenhedini (Verhoeff, 1934) Disphaerobius loricatus (Sseliwanoff, 1881) comb. comb. nov. nov. Distribution (Fig. 30): Steppe zone from the Sol-Iletsk District, Orenburg Area, Russia in the west to the East Kazakhstan Region of Kazakhstan (Sseliwanoff 1881) in the east.
