Type locality.

Description.

Size, form, color, head, prothorax, pterothorax, abdomen, genitalia, and distribution as in description of the genus.

Derivation of specific epithet.

The patronym howdenorum  honors Henry and Anne Howden, collectors of the holotype. The Howdens collected several examples included in the type series of Tachyxysta howdenorum  two decades apart in different locations.

Remarks.

Despite its superficial resemblance to the genus Xystosomus  , Tachyxysta howdenorum  possesses a combination of characters that support its placement among the Tachyina  but discourage its membership in any previously described tachyine genus; Tachyxysta howdenorum  has an apicolaterally notched protibia and an apical recurrent groove reminiscent of Tachyta  , but lacks the denticulate tarsal claws diagnostic for that genus (Erwin, 1975).
