Vesperopsis subgenus Contrangularia

"VESPEROPSIS subgenus CONTRANGULARIA" (Wan Chuanbiao and Zhang Ying, 1990, p.11,13–14) He Chengquan et al. 2009, p.307.  Emendation: Mao Shaozhi et al., 1999, p.154–155, as Contragularia.  Combination not validly published: no clear indication of rank.  We assume that the rank of subgenus was implied by He Chengquan et al. (2009) and so treat it as such here; but in doing so do not intend to validate the name.  Taxonomic senior synonym: Vesperopsis, by implication in He Chengquan et al. (2009, p.307).  Originally Contrangularia, subsequently Vesperopsis subgenus Contrangularia (name not validly published).  Type: Wan Chuanbiao and Zhang Ying, 1990, pl.3, fig.2, as Contrangularia reticulata.
