'''''Neurhermes''''' is a genus of dobsonflies in the family Corydalidae.

== Description == Questions about whether ''Neurhermes'' and ''Protohermes'' are separate genera have been raised repeatedly, with several species being transferred between the two.<ref name="Pdiff">{{Cite journal |last=Liu |first=Xingyue |last2=Yang |first2=Ding |date=2006 |title=The ''Protohermes differentialis'' group (Megaloptera: Corydalidae: Corydalinae) from China, with description of one new species |journal=Aquatic Insects |volume=28 |issue=3 |pages=219–227 |doi=10.1080/01650420600980297 |issn=0165-0424}}</ref> ''Neurhermes'' can be differentiated from ''Protohermes'' by presence of protrusions from the sternite plate.<ref>{{Cite journal |last=LIU |first=XINGYUE |last2=LÜ |first2=YANAN |last3=ASPÖCK |first3=HORST |last4=YANG |first4=DING |last5=ASPÖCK |first5=ULRIKE |date=2015-10-27 |title=Homology of the genital sclerites of Megaloptera (Insecta: Neuropterida) and their phylogenetic relevance |journal=Systematic Entomology |volume=41 |issue=1 |pages=256–286 |doi=10.1111/syen.12154 |issn=0307-6970}}</ref> Geologic uplift likely resulted in speciation across mainland southeast Asia, followed by dispersal to Sundaland.
