Hemilepistus pavlovskii Borutzky, 1954: 477 View in CoL .

Material examined. Holotype, male, 30 mm, Kazakhstan, Almaty region, near Jarkent , 1 June 1938 ( ZMMU, Mc- 802); same data as holotype, six males, fourteen females and one juv. ( ZMMU, Mc-802).

Redescription. Maximum length of both male and female: 30 mm. Color pale brown in fixative with usual muscle spots ( Fig. 4A View FIGURE 4 ).

Head with well developed quadrangular lateral and pointed median lobes; frons without an incision in the middle; vertex with several rounded tubercles of more or less the same size ( Figs 4A View FIGURE 4 ; 5A View FIGURE 5 ). Antenna long, fifth article of peduncle to flagellum ratio 1.5:1; flagellum with two articles equipped with long setae, proximal article about 2.5 times as long as distal one ( Fig. 5B View FIGURE 5 ).

Pereon tergite I with rounded hind margin, granulated with several rounded tubercles. Pereon tergites II–III with less tubercle. Pereon tergites IV–VII smooth ( Figs 4A, B View FIGURE 4 ; 5A View FIGURE 5 ).

Pleon smooth, with continuous outline with pereon ( Fig. 4A View FIGURE 4 ); telson short, triangular, with concave sides and acute apex, not surpassing uropod protopodites ( Figs 4C View FIGURE 4 ; 5C View FIGURE 5 ). Uropod protopodites large, exopodites cylindrical, up to four times as long as telson ( Fig. 5C View FIGURE 5 ).

Pleopod exopodites I–V with monospiracular covered lungs ( Fig. 6B–G View FIGURE 6 ).

Male: Pereopod I merus and carpus without brushes of setae on ventral margin ( Fig. 5D View FIGURE 5 ). Pereopod VII ischium with straight ventral margin; merus and carpus equipped with strong spine setae ( Fig. 5E View FIGURE 5 ).

Pleopod endopodite I straight; apex bearing a finger-like lobe with a line of small setae on inner margin, surpassing the summit of endopodite ( Fig. 6A View FIGURE 6 ). Pleopod exopodite I with small rounded hind lobe ( Fig. 6B View FIGURE 6 ). Pleopod exopodite II with faintly concave outer margin ( Fig. 6D View FIGURE 6 ), endopodite as long as exopodite ( Fig. 6C View FIGURE 6 ). Pleopod exopodites III–V as in Fig. 6 View FIGURE 6 E-G.

Remarks. This species is close to H. ruderalis in the shape of head, telson, pereopods and in dorsal tuberculation, but differs in males regarding having elongated uropod exopodites and the shape of pleopod endopodite I with a finger-like lobe at the apex which protrudes the summit of endopodite.

Distribution. Kazakhstan.
