Miridiba youweii – Gao et al . 2019: 462 (species list; in key). Diagnosis See Gao et al . (2018) . Remarks Gao et al . (2018) described Miridiba youweii based on the male holotype and 110 paratypes ( 71 males and 39 females ) conserved in IZCAS. Antenna 9-segmented, pronotal surface densely punctate and parameres with two dorsal and two ventral branches ( Gao et al . 2018 : fig. 4) allow us to include M. youweii in morphotype I “ Trichophora ”. Distribution China ( Guizhou , Yunnan , Zhejiang ) Species included in Morphotype II “Gressitti” The group is composed of two species, which are characterized by antenna 10-segmented, pronotal surface scattered punctate (distance between punctures greater than diameter of puncture), and male and female genitalia as specified above.
