Mayana ramosus
(Barber, 1938)
Mayana ramosus is a of true in the Oxycarenidae, first described by Barber in 1938. The Mayana is a small group within the lygaeoid complex, and this species is one of few documented members. Records indicate occurrence in the United States. Like other Oxycarenidae, it is presumed to be a seed-feeding heteropteran, though specific biological details remain poorly documented.

Identification
Mayana ramosus can be distinguished from other Oxycarenidae by features of the male genitalia, particularly the structure of the parameres and , which were characterized in the original description. The name 'ramosus' (Latin for 'branched') likely refers to branching structures in these genitalic components. External habitus characters for field identification are not well established in available literature.
Distribution

Taxonomic history
Originally described in a different (exact original combination requires verification). The genus Mayana was established to accommodate with distinctive male genitalic within the lygaeoid radiation. The Oxycarenidae was elevated from status based on phylogenetic studies of the Lygaeoidea.
Research status
This is known from very few specimens and has not been the focus of modern systematic or ecological study. Most information derives from the original description and subsequent cataloguing works.
