Omalorphanus is monotypic genus of beetles in the family Staphylinidae, the rove beetles, where it is placed in the subfamily Omaliinae. The only species is Omalorphanus aenigma . [2] [3] The genus and the species were described by John Milton Campbell and Donald S. Chandler in 1987 from the H.J. Andrews Experimental Forest (Oregon) at elevations of 3,500 feet (1,100 m) to 4,000 feet (1,200 m). It was described by them as unusual for its number of unusual morphological features, which made the placement of the species difficult. [1]

Taxonomy

Omalorphanus was assigned to the subfamily Omaliinae for its "unique and complex omaliine-type defense gland (a gland that by that by emitting an offensive secretion or vapor serves to repel enemies) on sternite 8" and for the distinct spiracles on tergites 2–6. These characteristics limited the genus to the subfamilies Omaliinae, Microsilphinae and Empelinae . According to Campbell and Chandler, the Microsilphinae consisted of 3 genera from the southern hemisphere and was also considered to be a tribe of Omaliinae, while Empelinae was a monotypic subfamily, only consisting of one genera and species which was unknown to them.

The rove beetles are a family (Staphylinidae) of beetles, primarily distinguished by their short elytra that typically leave more than half of their abdominal segments exposed. With over 66,000 species in thousands of genera, the group is one of the largest families in the beetle order, and one of the largest families of organisms. It is an ancient group that first appeared during the Middle Jurassic based on definitive records of fossilized rove beetles, with the Late Triassic taxon Leehermania more likely belonging to Myxophaga. They are an ecologically and morphologically diverse group of beetles, and commonly encountered in terrestrial ecosystems.

Many species of Staphylinidae have developed complex interspecies relationships with ants, known as myrmecophily. Rove beetles are among the most rich and diverse families of myrmecophilous beetles, with a wide variety of relationships with ants. Ant associations range from near free-living species which prey only on ants, to obligate inquilines of ants, which exhibit extreme morphological and chemical adaptations to the harsh environments of ant nests. Some species are fully integrated into the host colony, and are cleaned and fed by ants. Many of these, including species in tribe Clavigerini, are myrmecophagous, placating their hosts with glandular secretions while eating the brood.

Cenaspis aenigma is a species of colubrid snake in the subfamily Dipsadinae and the only member of the monotypic genus Cenaspis. It is endemic to the highlands of western Chiapas, Mexico, where it was described from a single, partially digested male specimen found in the stomach of a Central American coral snake. This is referenced in its generic name, as cena is Spanish for "dinner". Despite being partially digested, the specimen still displayed many unique traits, including undivided subcaudals for the full length of the tail, as well as a simple hemipenis completely covered in calyces with a largely non-bifurcated sulcus spermaticus. These traits are not known from any other colubroid snake in the Western Hemisphere.
