species but dorsal spur on article 2 of the telopodite not recognisable. Pretarsus without spurs, with well-developed dorsal brush. The angle between the longitudinal axes of pretarsus and article 3 of telopodite slightly more than 100° (Fig. 3), which is quite unusual condition in Scolopendromorpha.

<paragraph pageId="3" pageNumber="42">Forcipular segment: coxosternite without any visible sutures (including thechitin-lines). Anterior margin of coxosternite evidently convex (Fig. 3), divided by a median diastema into two low additionally sclerotised lobes; each lobe bearing a longseta. Trochanteroprefemoral process absent. Tarsungula normal.</paragraph>

Tergite 3 with a very characteristic thin oblique sutures bordering the anterior corners of tergite. Tergites 2-22 with complete paramedian sutures, tergites 3-21(22)withlateral longitudinal sutures (Fig. 4). Tergite 23 lacking sutures, its posterior margin convex. Tergite margination virtually absent, only tergite 23 distinctly margined laterally.Tergite 23 much wider rather than long and nearly rectangular in shape; its lateral sides slightly rounded (Fig. 4). All tergites without medial keel; pretergites also missing.</paragraph>

Sternites 2-21 with definite and complete lateral margination (Fig. 5) through lateral longitudinal sutures (see Remark 2); endosternites absent. Sternite 23 trapeziform, with a few very short (spur-like) setae on lateral sides (Fig. 6), with a straight posterior margin.</paragraph>

<paragraph pageId="3" pageNumber="42">Legs: prefemur, femur and tibia with a few large setae (Fig. 5); tarsi with more numerous setae of various length and size. Tibia of legs 1-20 with a lateral spur; both, ventral tibial spur and tarsal spur absent. Tarsi of legs 1-21 (Fig. 5) without distinct division between tarsus 1 and 2; pretarsi long, thin and sharply pointed.Pretarsi of legs 1-22 with two thin and long (as long as 1/2 of pretarsus)accessory spines.</paragraph>

Coxopleural surface without setae.Posterior margin of pleuron of ultimate leg-bearing segment forming avery obtuse angle.</paragraph>

Ultimate legs (Fig. 8): slender, ca 9 mm long, width of prefemur ca 0.5 mm.Prefemur triangular in cross-section, with a standard row of 4 ventral spinous processes (Fig. 7), some spurs (strong, spine-like setae of various length) dorso-laterally and more numerous similar spurs dorso-medially (Fig. 4). All four prefemoral ventral spinous processes are of the same size, apically curved and ending in a pointed harpoon-like tip, which is accompanied by a long seta. Femurcylindrical,with 3 small spinous processes medially (Fig. 9) and 1 ventrally in the middle of femur (Fig. 10). Tibia cylindrical, with 2 small spinous processes medially: one close to its base and another at mid length (Figs 9, 10). Both femoral and tibial spinous processes are ac

by a single long ventral seta. Tibia practically as long as prefemur or femur. Tarsus well divided into tarsus 1 and tarsus 2 (Fig. 8), former as long as 1/2 of tibia. Tarsus 1 (Figs 8-10) is enlarged and clavate (bulbous); tarsus 2 thin, consisting of 19 (or 20) articles (Fig. 8). In a few places annulation of tarsus 2 is somewhat vague; for example, the very long ultimate article seems to consist of two articles, which are not well divided. Ultimate legs without pretarsus.
