Figures 83, 84

Types. Holotype ♀, CHINA, Yunnan, Gongshan County, Cikai Township, Dahaituo, 27.78440°N, 98.46038°E, alt. 3363m, 13 August 2006, Peng Hu leg. (Hu060813).

Etymology. This epithet derives from the Latin adjective “ rutundus ”, meaning “round” and refers to the round spermathecae in the epigyne.

Diagnosis. This new species resembles Curtimeticus nebulosus Zhou and Li, 2014 in having the similar wide ventral plate and the copulatory openings at the junction of dorsal and ventral plate (Fig. 83B, C; Zhou and Li, 2014, fig. 28C), but can be distinguished by the shorter and circular copulatory duct in C. rutundus sp. nov. (Fig. 83B, C), whereas straight in C. nebulosus (Zhou and Li, 2014, fig. 28C). Spermathecae globular in C. rutundus sp. nov. (Fig. 83B, C), whereas elliptical in C. nebulosus (Zhou and Li, 2014, fig. 28C).

Epigyne (Fig. 83B, C): Ventral plate sclerotized, wide, mid ventrally grooved; copulatory openings at the junction of dorsal and ventral plate; copulatory ducts short, located mesally, forming a loop before entering the spermathecae; spermathecae globular; fertilization ducts short, extending mesally.

Male. Unknown.
