Description

See description Table 1 and Fig. 1a, Fig. 3a, Fig. 4a.

Diagnosis

Male. In the group VIII key of Borgmeier (1966), M. baileyae keys to M. pygmaeoides [now considered to be M. berndseni (Schmitz 1919)], to which it is very similar. The most notable difference between these similar species is in the overall lighter coloration of M. baileyae , which has legs that are clearly yellow, not light brown like M. berndseni . This subtle difference in coloration is easily confirmed by looking at the hind femur, which is largely yellow but has a dark brown spot apically. This contrasts with the femur of M. berndseni which, although it does darken slightly apically, is clearly a light, mottled brown throughout. Details of the genitalia also differ between the species although there, too, they are quite similar. In contrast to the brown, rounded left process of the hypandrium found in M. berndseni , M. baileyae has a left lobe that is large, pale and ends abruptly, appearing almost as if it has been broken or cut (Fig. 4a). This lobe is so light, in fact, that you can see parts of the penis-complex through the lobe (visible as darkened areas in Fig. 4a).
