Table 1. Comparison of Mexican and Central American Corthylus species with truncate declivities. Declivital crest: degree of elevated margin on circumdeclivital ring, scale of 1–10 where 10 represents a complete ring without interruption. Armature of declivital interstriae 1 and 3: costate= prominently elevated; serrate=elevated with prominent denticles; dentate=denticles prominent but not joined into single structure; elevated=elevated with respect to interstria 2 but not prominently so; inflated=interstrial area higher than adjacent interstriae but not costate.
