Diagnosis.
Males of
M. juvenca
comb. nov.
are recognized by the presence of an elongated TA, in combination with its enlarged apico- and meso-retrolateral folds (Fig. 1406). Females can be distinguished from
M. botuliformis
sp. nov.
by the much smaller median scape on the epigynal plate (Figs 1398–1399).
Redescription.
