Pseudomelanactini
Arnett, 1967
Pseudomelanactini is a tribe of () within the Agrypninae, established by Arnett in 1967. The group comprises multiple distributed primarily in the Neotropical region. These share morphological features with related elaterid tribes but are distinguished by specific combinations of characters in the stage. The tribe is relatively understudied compared to more economically significant elaterid groups.

Identification
Members of Pseudomelanactini can be distinguished from other Agrypninae tribes by specific combinations of characters in the prosternal process, mesosternal cavity, and antennal structure. Detailed morphological examination is required for definitive tribal assignment, as superficial similarities exist with related groups such as Melanactini and other Agrypninae tribes. Identification to or level requires examination of male genitalia and other fine structural details.
Distribution
Primarily Neotropical, with records from Central and South America. The distribution aligns with that of the Agrypninae, which shows strong tropical affinity.

Taxonomic History
The tribe was erected by Ross H. Arnett Jr. in 1967 as part of his comprehensive work on classification. The group has undergone limited subsequent revision, and its internal composition and relationships remain subjects for future systematic study.
Research Status
Pseudomelanactini is among the less-studied tribes within . No comprehensive modern revision exists, and -level diversity is likely underestimated. Most available information derives from regional faunistic surveys rather than focused systematic studies.
