Note. In Rino (1972), Pl. 6 fig. 10-11 it is probably an illustration of Monomorphina parapyrum Kim, Triemer & Shin ( Kim et al. 2013). Most species in the genus Monomorphina can only be identified based on molecular characters, including this one (see Kosmala et al. 2007).

M. trypanon has never been formally synonymized because the diagnostic feature of the taxa (dual pellicle ribs) has never been seen in modern studies (see discussion in Kosmala et al. 2007) so it is proposed that it should be a synonym of M. pyrum . In this case the illustration in Rino (1972: Pl. 6, figs. 8-9) is that of Monomorphina pyrum ( Kosmala et al. 2007) .
