Type material.

Holotype ♂ and paratypes 4♂ 9♀ (IZCAS), China: Hainan Province, Changjiang Lizu Autonomous County, Shilu Town, in leaf litter in rainforest (19.20000°N, 109.06667°E), 22.III.2005, Y. Tong, Y. Song and X. Han leg. Examined.

Other material examined.

3♂ 8♀ (NHMSU-HA081), China: Yunnan Province, Mengla County, Menglun Town, Xishuangbanna Tropical Botanic Garden, tropical rainforest (21.917°N, 101.275°E; 558 m), 5.X.2017, Y. Lin and Y. Li leg.; 1♂ juvenile (NHMSU-HA081) and 1♀ (NHMSU-HA081) used for sequencing, GenBank: MT992002 and MT992001, same data as for preceding; 1♂ 3♀ (NHMSU-HA059), China: Yunnan Province, Menglun Nature Reserve, secondary tropical seasonal moist forest (21.91197°N, 101.28233°E; 645 ± 17 m), 5-12.I.2007, G. Zheng leg.

Diagnosis.

This species differs from all other species of Crassignatha by the long embolus coiling into two loops (Fig. 27A View Figure 27 ) and by the long copulatory ducts connected to the anterolateral margin of the spermathecae, coiled into three loops below spermathecae (Fig. 27D, E View Figure 27 ). Its dorsoventral dichroism is also a prominent feature (Fig. 26A-D View Figure 26 ).

Description.

See Lin and Li (2009).

Taxonomic justification.

A series of combinations: the form of the male palp and the configuration of the epigyne, the chelicerae fused at the base, and the male clasping setae distoventrally on tibia II suggest that this species is more similar to Crassignatha than Patu . It shares homologous characters of Crassignatha , such as a large median apophysis on a slightly oblate male palpal bulb and globular spermathecae rather than a nearly oviform male palpal bulb and claviform spermathecae as in Patu . Thus, we propose a new combination, Crassignatha shiluensis (Lin & Li, 2009) comb. nov., transferring it from Patu .

Distribution.
