Miridiba xingkei – Gao et al . 2019: 462 (species list; in key). Diagnosis See Gao et al . (2018) . Remarks Gao et al . (2018) described Miridiba xingkei based on the male holotype and thirteen paratypes ( 4 males and 9 females ) conserved in IZCAS and NWAFU of China . This species shows features that characterize genital morphotype IX “ Ciliatipennis ”. The parameres have the characteristic dorsal tubular complex ( Gao et al . 2018 : figs 3g –i) with dorsal and ventral branches (upper and lower parts) ( Gao et al . 2018 : fig. 3h) forked at distal end ( Gao et al . 2018 : fig. 3g ), showing in lateral view the distinctive concavity at distal end ( Gao et al . 2018 : fig. 3h). On the other hand, the ventral branches appear reduced but obvious, fused laterally to dorsal tubular complex forming an apparent lateral scar ( Gao et al . 2018 : figs 3h–i). According to these features, we include M. xingkei in the genital morphotype IX “ Ciliatipennis ”. Distribution China ( Yunnan ).
