FONTS OF TAXA NAMES:

Italics — names of genus-group and species-group, everywhere (in tables, index, titles, and texts); no other words are written in Italics (according to ICZN recommendation B6)

Small capitals — circumscriptional names (nomina circumscribentia), only in tables and index; in titles and texts these names are written by regular font.

Regular font — typified names (hierarchical, ranking and universal), everywhere.
