It differs from both of these species by its relatively shorter pronotum (width 1.9 times length—in + +M. changonensis + +and + +M. proximus + +it is 1.5 times length) and black color with aeneous reflection. It differs further from + +M. changonensis + +by its frontal sulcus with the median part not as deep as the upper and lower extremes and by the male genitalia. From + +M. proximus + +, it differs further by its larger size and having the elytra widest at the apical one-third rather than the middle. + + + + +Etymology. +The species is named for Rio Guayllabamba, which flows near the +type +locality down the Pacific slope of the Andes Mountains. + + + + \ No newline at end of file
