Name

Badister Clairville, 1806 – Wikispecies link – Pensoft Profile

• Badister Clairville, 1806: 90
• Amblychus Gyllenhal, 1810: 74

Diagnosis

In addition to the features presented in the generic diagnosis and description above, all of the Western Hemisphere species of the typical subgenus have the right mandible deeply notched (Fig. 2, mn), and a row of setae on each latero-ventral margin of tarsomere 5. Another useful attribute in distinguishing the subgenera is the relative length of the hind tarsi. In adults of Badister and Trimorphus, the posterior tarsi are more than 3/4 the length of the hind tibiae; in Baudia, the hind tarsi are perceptibly relatively shorter.

Geographic Distribution

(Western Hemisphere).—The known range of this subgenus includes Amazonian Perú in South America, Middle American countries of Costa Rica, Honduras, Belize and México, and the North American countries of USA and Canada.
