Neurhermes

Questions about whether Neurhermes and Protohermes are separate genera have been raised repeatedly, with several species being transferred between the two.^[1] Neurhermes can be differentiated from Protohermes by presence of protrusions from the sternite plate.^[2] Geologic uplift likely resulted in speciation across mainland southeast Asia, followed by dispersal to Sundaland.

Species in Neurhermes and some in Protohermes were originally placed in the deprecated genus Hermes.^[3] The color patterns have been described as an example of Batesian mimicry of toxic zygaenid moths.^[1] Neurhermes males produce large nuptial gifts of gelatinous spermatophores, but have small mandibles and limited sexual dimorphism compared to many other dobsonflies.^[4] Unlike most other dobsonflies, Neurhermes are active during the day, possibly meaning the dark wing color is more related to preventing hybridization with other sympatric genera.^[5]

Nanocladius asiaticus have a commensal relationship with many Asian Corydalidae species, and Neurhermes maculipennis serves as the host in the Malay peninsula.^[6]

Neurhermes, when it is recognized as a valid genus, contains the following species, which are otherwise considered to belong to the genus Protohermes:^[7]
