in body proportions and coloration, but is clearly
larger than M.
perparva.
Also, petrigena has a dark belly with an irregular
white blotch. Females reach 18 mm snout-vent
length, males are smaller.

Tadpoles were described (verbally, no image) in
Inger & Steubing 2005 and appear to be similar
to those of M.
perparva.
The tail bears a brown cross band in the distal
third. The tail terminates in a short, narrow tip.
Tadpoles are mid water column suspension feeders. They lack keratinized mouthparts. The mouth is terminal. The spiraculum is located in a medial position on the venter.
The eyes of the tadpole are far lateral on the head.
