Etymology.

This name comes from the Latin ‘tres-’, meaning ‘three’, and the Latin word ‘coloratus’, meaning ‘colored’, and the combination refers to the three transversal bands of different colors on the dorsum of the abdomen; adjective.

Diagnosis.

This species is similar to Parameioneta biobata Tu & Li, 2006 by the shape of embolus ( Tu and Li 2006: fig. 8C; Fig. 85D) and the median membrane ( Tu and Li 2006: fig. 8B); differs in the following aspects: Parameioneta tricolorata sp. n. has a much smaller tibial dorsal apophysis (Fig. 85B); the shape of radix is different in two species ( Tu and Li 2006: fig. 7B; Fig. 85A); the structure of lamella characteristica differs in two species. The color pattern of abdomen in Parameioneta tricolorata sp. n. (Fig. 86C) is quite similar to the type species Parameioneta spicata Locket, 1982 ( Locket 1982: fig. 72). The epigyne of female resembles greatly that of Parameioneta spicata ( Locket 1982: fig. 78), but differs in the wider distal end of the scape.
