Diagnosis.

Yunguirius ornatus can be distinguished from other species of this genus as follows: 1) atrium inverted trapezoid (Fig. 3A ; fig. 53 in Wang et al. 1990) in Y. ornatus , but cordiform (fig. 245A in Zhu et al. 2017) in Y. subterebratus and Y. xiangding sp. nov. (Fig. 4A ), or subrounded (Fig. 2A ) in Y. duoge sp. nov. and (fig. 28 in Peng and Wang 1997) Y. terebratus ; 2) median septum present (Fig. 3A ; fig. 53 in Wang et al. 1990) in Y. ornatus ; 3) copulatory opening away from each other and the midline (Fig. 3A ; fig. 53 in Wang et al. 1990) in Y. ornatus , but close to each other and the midline (fig. 245A in Zhu et al. 2017) in Y. subterebratus and (Fig. 4A ) Y. xiangding sp. nov.; 4) patellar apophysis long, extending beyond the patella to the middle of the tibia (fig. 3 in Zhang 1993) in Y. ornatus , but extending to the quarter of the tibia (fig. 31 in Peng and Wang 1997) in Y. terebratus ; and 5) lateral tibial apophysis short, c. 1/4 the length of retrolateral tibial apophysis (fig. 3 in Zhang 1993) in Y. ornatus , but c. 1/3 (fig. 31 in Peng and Wang 1997) in Y. terebratus .

Leg formula 1> 4> 2> 3. Sternum c. 1.5 times longer than wide. Epigyne (Fig. 3A, B ): posterior epigynal sclerite rectangular, atrium with white margins, outside with brownish markings, fold bell-jar-shaped, c. 2 times larger than hood; copulatory opening located anteriorly, away from each other, close to the lateral margin of the atrium; copulatory duct semilucent; spermatheca lamellar at first half, its head longer than the length of the copulatory duct; fertilization duct long and bent, c. 4 times longer than wide.
