Mallinella renaria Zhang & Zhang 2018, sp. nov.

Mallinella renaria sp. nov.

(Figs 9–11)

Type material. Holotype male (Z-Laos-11-64), LAOS, Champasak Province: Pakse City, Tad Etu (N 15°11', E 106°06'), 22 Nov. 2011, Z.Z. Gao leg. P aratypes: 8 female (Z-Laos-11-65-Z-Laos-11-72), same data as holotype.

Diagnosis. According to Dankittipakul et al. 2012, this species should belong to the cryptocera species-group by the following characters: the dorsal opisthosoma with lanceolate dorsal scutum in the male and a pair of anterior reniform patches (Figs 9A, C) and the RTA with two apophyses (Figs 10B, D, 11B). The new species can be distinguished from other species of the cryptocera -group by the relatively broad embolus with subterminal process, the shorter median apophysis and the epigyne with almost quadrangular plate (Figs 10A–C, E, F, 11A–E).

Etymology. The specific name is from Latin word “ renarius ”, in reference to the reniform patches of dorsal opisthosoma; adjective.

Chilum represented by a single sclerite. Chelicerae dark brown, without teeth on margins of fang furrows, terminal part with row of black setae; fangs short. Endites brown with apices paler and furnished with dense black scopula. Labium triangular, 0.41 long, 0.48 wide, dark brown.

Opisthosoma oval, longer than wide, covered with black short hair, with wide and lanceolate dorsal scutum, with four pairs of white anterior patches, followed posteriorly by two transversal median bands; lateral part with white patches; anterior part of venter slightly sclerotized, yellow, median and posterior part pale with some black and white patches. Spinnerets (Fig 9B) yellow brown, ringed with blackish patches, with row of thin spines in front of spinnerets.
