Morphologically close genera and how to distinguish them
Rhodanthidium species have at least one apical tooth on the dorso-apical plate of the posterior tibia.
Afranthidium, Anthidium, Icteranthidium & Pseudoanthidium species don't have an arolium between their claws.
Anthidiellum species have a subrectangular, posteriorly extended scutellum and are much smaller.
Eoanthidium species have a carinate antennal fossa.
Stelis species may have pointed axillae, males have two widely separated apical teeth on their anterior and median tibiae and females have no ventral scopa.
Melitturga species have a truncated marginal cell, a second recurrent vein anteriorly connecting at the second submarginal cell, males with enlarged eyes and females without a ventral brush.

General comments on Trachusa species identification
Diagnostic characters for species identification are located on the mandibles, maxillary palps, scutellum and axillae, as well as genitalia and sternites. These area should be made visible as far as possible.
