Diagnosis. Antennae five-segmented, first and second antennomeres subequal in length; segment X of pygophore wider than long, apex rounded with abundant setae; lateral angles of laterotergites VIII projected well beyond the line connecting the mesial thrichobotria of urosternite VII, and covering completely the base of laterotergites IX.

Male. Genitalia: conical projection of the ventral rim of pygophore single, with apical setae; posterolateral angles narrowly rounded at apex, medial projection of posterolateral angles tumescent, much shorter than the dorsal limit of segment X in lateral view; lateral projection of dorsal rim thin, spine like and lateral to the posterolateral angle; segment X covered by setae, as wide as high in posterior view, and as wide as long in ventral view ( Fig. 4 E–H ); apical projection of parameres short, with tuft of setae, largest axis of head less than half the length of stem ( Fig. 5D–F ); phallus with 2 + 2 lateral projections of vesica; ductus seminis distalis twisted, bifid at secondary gonopore; thin conjunctiva accompanying the full length of ductus seminis distalis ( Fig. 5P–R ).

Female. Genitalia: Valvifers VIII longer than wide, covering completely the basal portion of the laterotergites IX; lateral angles well projected, surpassing the lateral margin of laterotergites IX and the imaginary line connecting the mesial thrichobotria of urosternite VII; lateral margin of valvifers VIII deflected, covering the limit between laterotergites VIII and IX ( Fig. 6B ). Folds of valvulae IX with conical microsculptures; thickening of vaginal intima thin and translucent; ring sclerites half the diameter of orificium receptaculi, this about half the width of vaginal intima ( Fig. 7B ).

Comments. Considerations on the distribution and differential diagnosis of M. spinolae are as treated in the comments made for M. reticulare .
