Type material.

Holotype ♂ (IZCAS-Ar44186), Vietnam: Vinh Phuc Province: Tam Dao National Park, Acacia Plantation, 1-30.III.2008, D.S. Pham leg. Paratypes 2♂1♀ (IZCAS-Ar44187-44189), same data as holotype; 1♂1♀ (IZCAS-Ar44190-44191), Tam Dao National Park, 1-30.I.2008, same collector.

Etymology.

The specific name is a patronym in honor of Dmitri V. Logunov (Manchester, UK), a leading arachnologist in jumping spiders, who has contributed significantly to the taxonomy of jumping spiders from Vietnam; noun (name) in genitive case.

Diagnosis.

The male of Chinattus logunovi sp. nov. can be easily distinguished from other congeners by the presence of RCA (Fig. 3B ). The female of this new species resembles that of C. prabodhi Basumatary, Das, Caleb & Brahma, 2020 by the absence of epigynal plate, but it can be easily distinguished by the spermathecae, which are anterior to copulatory openings (Fig. 4B ), whereas almost as level as copulatory openings in C. prabodhi ( Basumatary et al. 2020: figs 8-11), and by the accessory glands of copulatory ducts, which are anteriorly extending (Fig. 4B ), whereas posteriorly extending in C. prabodhi ( Basumatary et al. 2020: fig. 11).

Description.

Male (Figs 3 , 4C, D, F, G ). Total length 5.45. Carapace 2.95 long 2.23 wide. Abdomen 2.59 long, 1.91 wide. Clypeus 0.14 high. Eye sizes and inter-distances: AME 0.59, ALE 0.36, PLE 0.30, AERW 1.94, PERW 1.73, EFL 1.14. Legs: I 7.52 (2.13, 1.33, 1.88, 1.43, 0.75), II 4.81 (1.45, 0.88, 1.10, 0.88, 0.50), III 6.21 (2.08, 0.93, 1.45, 1.25, 0.50), IV 5.74 (1.68, 0.93, 1.20, 1.38, 0.55). Carapace sub-square, slightly narrowed anteriorly, red-brown to dark brown, covered with setae, denser anteriorly, with fan-shaped, red-brown area medially; fovea bar-shaped, longitudinal, dark. Chelicerae red-brown, with two promarginal teeth and one retromarginal fissidental tooth with six cusps. Endites broadened distally, bearing dense setae at distal half on inner margins. Labium red-brown, almost linguiform, paler distally. Sternum colored as labium, longer than wide, with straight anterior margin. Legs yellow to brown, spinous. Abdomen almost oval, dorsum brown, spotted, with arc-shaped, pale stripe anteriorly, two pairs of muscle depressions, several pairs of irregularly shaped spots mediolaterally, several wave-shaped or straight, transverse stripes posteromedially; venter colored as dorsum, with two pairs of pale, longitudinal dotted lines. Palp (Fig. 3A-D ): tibia longer than wide, with short, strongly sclerotized retrolateral apophysis curved medially, and with rather pointed tip; cymbium longer than wide, with flat, apically blunt baso-retrolateral apophysis; bulb longer than wide, swollen medio-posteriorly, with semi-circular posterior lobe extending prolaterally; embolus strongly sclerotized, slightly curved, originates from antero-prolateral portion of bulb, with rather pointed tip, directed anteriorly in ventral view.

Female (Fig. 4A, B, E ). Total length 5.56. Carapace 2.52 long 1.96 wide. Abdomen 3.01 long, 2.44 wide. Clypeus 0.15 high. Eye sizes and inter-distances: AME 0.54, ALE 0.34, PLE 0.29, AERW 1.66, PERW 1.57, EFL 1.03. Legs: I 4.76 (1.45, 0.88, 1.13, 0.80, 0.50), II 4.09 (1.13, 0.80, 1.01, 0.70, 0.45), III 5.64 (1.95, 0.88, 1.18, 1.13, 0.50), IV 5.29 (1.68, 0.70, 1.13, 1.25, 0.53). Carapace similar to that of male except paler. Chelicerae with one retromarginal fissidental tooth with seven cusps. Abdomen pale brown, with two pairs of muscle depressions medially. Epigyne (Fig. 4A, B ): wider than long, with oval structure (maybe a transformation of epigynal hood) between copulatory openings; copulatory openings posterolaterally located, opened laterally; copulatory ducts thick, twisted, strongly curved, with proximal accessory glands; spermathecae indistinct; fertilization ducts lamellar, transversely extending.

Distribution.

Known only from the type locality in Vinh Phuc Province, Vietnam.
