Abstract

The aim of this study is to review the family Behningiidae and Potamanthidae in Thailand. Two genera and three species of Behningiidae are recognised:Protobehningia mergaPeters & Gillies, 1991,Behningia baeiMcCafferty & Jacobus, 2006, andBehningia nujiangensisZhou & Bisset, 2019, which is newly reported from Thailand. The egg structure ofB. nujiangensisis described for the first time using scanning electron microscopy. The larva ofP. mergais redescribed and its distribution is expended northward with a new record from Chiang Mai province. Two genera and five species of Potamanthidae are identified:Potamanthus formosusEaton, 1892,Rhoenanthus magnificusUlmer, 1920 (new record for Thailand),Rhoenanthus obscurusNavás, 1922,Rhoenanthus distafurcusBae & McCafferty, 1991, andRhoenanthus speciosusEaton, 1881. Our morphological evidence is supported by COI data for the family Potamanthidae. Diagnostic characters, distributions, and keys are presented for the larvae of all known species of Thai behningiid and potamanthid mayflies.
