Diagnosis. In D. loricatus males, T 14 is the broadest, but without two lobes ( Figs 22 View FIGURES 21 – 24 & 26 View FIGURES 25 – 29 ). In females, T 12 is of similar length and width, concave at the rear edge, without formed lobes ( Farzalieva & Zalesskaja 2003: Fig. 10 View FIGURES 10 – 15 ). 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 View FIGURES 21 – 24 ), the trochanteroprefemur is slightly concave on the inner surface, with an almost straight, ventral, chitinous rib ( Fig. 24 View FIGURES 21 – 24 ). All males have T 14 and Tim broadened and serrate, especially strongly broadened is T 14, their surface roughly rugose ( Figs 22 View FIGURES 21 – 24 & 26 View FIGURES 25 – 29 ). 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.
