BB6787BC1731E61CFF0837E9C097F911.taxon	diagnosis	Diagnosis. The new genus is distinguished (together with Leclercera and Althepus) from all other genera of Ochyroceratidae by the large size, the presence of a denticle on the cheliceral promargin and the rounded maxillae. It is distinguished from Leclercera and Althepus by the absence of a retrolateral protrusion on the tibia or cymbium of the male palp and by the absence of a conductor.	en	Liu, Chang, Li, Fengyuan, Li, Shuqiang, Zheng, Guo (2017): Five new genera of the subfamily Psilodercinae (Araneae: Ochyroceratidae) from Southeast Asia.

BB6787BC1731E61BFF083405C715FC96.taxon	diagnosis	Diagnosis. Specimens of the two species of Luzonacera are very similar but can be distinguished as follows. The carapace in both sexes of L. chang Li & Li, sp. nov. has a medial rounded brown area (versus three longitudinal bands in both sexes of L. duan Li & Li, sp. nov.). The male of this species is easily recognized by the long spiral embolus (versus shorter in L. duan Li & Li, sp. nov.) and the relatively light constriction of the central part of the bulb (versus constriction more pronounced in L. duan Li & Li, sp. nov.). The female is diagnosed by the two pairs of curved, elongate, distally swollen spermathecae (versus curves of spermathecae relatively more twisted in L. duan Li & Li, sp. nov.).	en	Liu, Chang, Li, Fengyuan, Li, Shuqiang, Zheng, Guo (2017): Five new genera of the subfamily Psilodercinae (Araneae: Ochyroceratidae) from Southeast Asia.

The female of this species is diagnosed by the elongate, curved spermathecae which narrow distally (Fig. 10 A) (versus spermathecae of same width throughout their length in S. exilis). Description. Male (holotype). Total length 2.02; carapace 0.70 long, 0.75 wide; abdomen 1.13 long, 0.63 wide. Carapace round, yellow with some brown bands of differing width (Fig. 10 C). Fovea shallow.

Zhou & Z. Chen. Paratype. 1 female, same data as holotype (IZCAS). Etymology. The species name is a noun in apposition derived from the Chinese pinyin " jǐan " (" simple ") and refers to the simple structure of the male palp. Diagnosis. The males of the two species of Thaiderces Li & Li, gen. nov. are very similar but can be distinguished as follows. The embolus of this species is relatively slender basally and the needle-like tip is smoothly curved (Figs 11 A – D) (versus relatively thick basally and with a slightly sinuous tip in T. vulgaris). The female of this species is easily distinguished by the relative length of the pairs of spermathecae: the medial spermathecae are elongate, the lateral spermathecae are greatly reduced (Fig. 12 A).
