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).
