Idiotrephes maior sp. n., a new species of water bug from Vietnam with morphological notes on I. chinai (Heteroptera: Helotrephidae)
- N/A
A new helotrephid, Idiotrephes maior sp. n. (Helotrephinae: Limnotrephini), is described (male, female) from North Vietnam and compared with the sympatric and widely distributed Oriental species I. chinai Lundblad, 1933. Description of macropterous morph and ovipositor of I. chinai is added to Lundblad's diagnosis of this species. Diagnosis of the genus Idiotrephes is expanded. Some morphological features of this genus are compared briefly with the same of related genera of Limnotrephini and two genera of Helotrephini (Hydrotrephes, Esakiella).
