Types.
Holotype: ♀ (IZCAS), Thailand, Satun Province, Thung Wa District, Cave without name, 07°3.04278'N, 99°48.03915'E, 28 m, 01.XII.2013, F. Ballarin.
Etymology.
The species name is a noun in apposition derived from the Chinese pinyin zuǐchún (lip) and refers to the overall structure of the spermathecae which is similar to a human lip.
Diagnosis.
Thaiderces zuichun sp. nov. is similar to T. miantiao sp. nov. but can be easily distinguished by a pair of stalked spermathecae with an oblong distal part connected to a wavy horizontal duct (vs. two pairs of strongly twisted spermathecae in T. miantiao sp. nov.).
Description.
Female. Total length 1.58; carapace 0.50 long, 0.63 wide; abdomen 1.08 long, 0.78 wide. Carapace round and brown, with three longitudinal purplish bands, median band rather pale and only half the length of the carapace, lateral bands three times wider than the median band ( Fig. 13C View Figure 13 ). Chelicerae brown ( Fig. 27G View Figure 27 ). Clypeus purple. Endites purple. Labium brown. Sternum with purplish pattern. Abdomen elongated, posterior with indistinct dark brown pattern ( Fig. 13C View Figure 13 ), ventrum with indistinct brown pattern, anterior epigastric area forming a semi-circle ( Fig. 13D View Figure 13 ). Legs uniformly brown; measurements: I missing, II 4.13 (1.09, 0.15, 1.25, 1.09, 0.55), III 3.45 (0.94, 0.16, 0.94, 0.94, 0.47), IV 4.70 (1.20, 0.20, 1.40, 1.30, 0.60). Endogyne: a pair of stalked spermathecae, with oblong distal parts, stalk almost equal in length to and half the width of the oblong distal part, connected by a wavy horizontal duct ( Fig. 13A View Figure 13 )
