Description

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

Diagnosis

Male. In the group VIII key of Borgmeier (1966), M. joanneae keys to couplet 11 where it differs from M. globipyga Borgmeier by lacking the globose genitalia of that species and from M. brevicostalis Wood 1910 by having unequal supraantennals and lacking the large notopleural cleft of that species. It should be noted that in order to key to M. globipyga , you must say that the first costal division is at most as long as second (couplet 10), which is not always accurate (but the alternative, of the first costal division being three-times as long as second, is much less accurate). Otherwise, the species simply fails to key at couplet 10. Within the Los Angeles fauna, this species is quite similar to M. mikejohnsoni , but differs in details of the genitalia, most noticeably with M. joanneae lacking the prominent trio of setae on the posterior of the epandrium (Fig. 83 in Hartop et al. 2015 versus Fig. 4d).
