Distribution.

Dominica, Montserrat, St. Lucia.

Remarks.

The tibiae in specimens from Montserrat are mostly yellow whereas those from Dominica and St. Lucia are mostly brown, but otherwise appear conspecific. The drawing of male genitalia of M. pseudonigripes in Robinson (1975: fig. 25) shows the surstylus pointed, but it is actually narrowly spatulate with tip shallowly concave or notched. This species belongs to the M. isobellae species group most notably in having the surstyli fused into expanded apical lobe with modified setae medially ( Bickel 1985). M. pseudonigripes is very similar to the Nearctic M. isobellae Bickel, but the latter species has the surstylus much broader apically with the tip not concave or notched.
