Note.

The common name, Saline Catarrh Beetles, proposed here follows my principle of translating the scientific name as strictly as possible. In this case, “coryza” comes from the Greek, koryza, meaning cold, catarrh, as in disease. Why Alluaud named the genus so is not known.

Diagnostic Combination.

Differing in adult attributes from those of its adelphotaxon, Schizogenius Putzeys, 1846, by the following: Pygidium not striate or with very subtly crenulate striae; antennomere 2 pluristose. In addition, mandibles prominent, nearly straight laterally, abruptly angulate near apices; lacinia asetose on outer margin; frontal carinae nearly perfectly regular, parallel, equidistant, and equally raised; frons evenly convex; neck not pitted or punctate dorsally; eyes reduced, bordered laterally by a distinct carina; gula broad; mentum not deeply emarginate at middle, with median tooth obsolete and epilobes short; tarsi short; paramedian carinae of sternum II short, widely spaced and poorly developed; median lobe of male genitalia neither arcuate nor abruptly deflexed in apical third; fused stylus and coxite of the ovipositor with one robust seta (Whitehead, 1966, 1972).

Geographic Distribution.

Sea beaches, intertidal lagoons on the edges of mangroves, and island shores of the Atlantic, Indian, and Pacific Oceans, the Caribbean Sea, Sea of Cortés, and the Gulf of México.
