Diagnosis.

Zabka cooki resembles Z. xuyei , comb. nov. in having similar copulatory organs, but it can be easily distinguished by the following: (1) the mediodorsal cymbial spines are absent (Fig. 24A, C ), whereas the spines are present in Z. xuyei ( Lin and Li 2020: fig. 5A, C); (2) the copulatory ducts are twisted proximally and lack accessory glands (Fig. 25B ), whereas they are not twisted and have proximal accessory glands in Z. xuyei ( Lin and Li 2020: fig. 6B); (3) the dorsum of abdomen has a pair of anterior, elongate-oval, pale yellow patches and a transverse, posterior, pale yellow band in both sexes (Fig. 25C, E ), whereas there are several chevrons in Z. xuyei ( Lin and Li 2020: fig. 6C, E).

Description.

Male (Figs 24 , 25C, D, F, G ). Total length 3.01. Carapace 1.82 long, 1.40 wide. Abdomen 1.24 long, 1.10 wide. Clypeus 0.08 high. Eye sizes and inter-distances: AME 0.44, ALE 0.29, PLE 0.25, AERW 1.41, PERW 1.23, EFL 0.85. Legs: I 3.99 (1.25, 0.63, 1.10, 0.63, 0.38), II 2.83 (0.90, 0.50, 0.68, 0.45, 0.30), III 3.61 (1.25, 0.53, 0.75, 0.78, 0.30), IV 3.51 (1.13, 0.50, 0.75, 0.80, 0.33). Carapace red to dark brown, covered with dense, brown setae, with square cephalic region bearing two pairs of scale setae, one pair between PLEs and PMEs and other pair near the posterior-inner margins of PMEs; fovea dark, longitudinal, linear. Chelicerae red-brown to dark brown, with two promarginal teeth and one retromarginal fissidental tooth with one cusp. Endites paler than chelicerae, broadened distally. Labium tapered, paler at distal end. Sternum almost oval, with sub-straight anterior margin. Legs pale yellow to yellow except femora I dark brown, with three and two pairs of ventral spines on patellae I and metatarsi I, respectively. Abdomen oval, dorsum pale yellow to dark brown, covered with white setae, with pair of anterolateral, elongate-oval, pale yellow patches and transverse, posterior pale yellow band; venter pale yellow to brown. Palp (Fig. 24A-C ): tibia longer than wide in retrolateral view, with medio-posterior notch, and straight RTA almost equal to its length and blunt apically; cymbium longer than wide, and tapered at distal half; bulb elongated, with sperm duct strongly curved at anterior half, with oval anterior lobe, and well-developed, posteriorly extended posterior lobe; embolus originates from the antero-prolateral portion of bulb, forming disc at base, remainder curved into nearly a complete circle, with blunt tip.

Female (Fig. 25A, B, E ). Total length 2.99. Carapace 1.59 long, 1.32 wide. Abdomen 1.37 long, 1.10 wide. Clypeus 0.08 high. Eye sizes and inter-distances: AME 0.44, ALE 0.29, PLE 0.24, AERW 1.37, PERW 1.21, EFL 0.89. Legs: I 3.24 (1.01, 0.55, 0.80, 0.55, 0.33), II 2.61 (0.80, 0.50, 0.58, 0.45, 0.28), III 3.33 (1.20, 0.50, 0.70, 0.65, 0.28), IV 3.26 (1.10, 0.43, 0.70, 0.73, 0.30). Habitus (Fig. 25E ) similar to that of male except darker and with denser white setae on carapace. Epigyne (Fig. 25A, B ) wider than long, with pair of round atria separated from each other by <1/6 of their width; copulatory openings slit-shaped, located at middle of inner portions of atria, separated from each other by ~ 1/4 of the atrial width; copulatory ducts long, extending transversely in opposite directions before ascending to the same level of anterior margins of spermathecae, finally connecting to anterior portion of spermathecae; spermathecae almost spherical, anteriorly located, touching each other; fertilization ducts originate from the middle of anterior margins of spermathecae, extending transversely.

Distribution.

Vietnam (Nghe An, Ninh Binh).
