M. biguttatus: Colombia, Peru (new record)
M. simillimus: Colombia


Generic Diagnosis: This genus is recognized by its elongate body; mottled coloration; prementum quadrate, medially grooved (Fig. 1); clypeus with anterior angles acute (Fig. 2), prelabrum often visible (Fig. 3); pronotum trapezoidal, widest medially, posterior margin medially concave or weakly tridentate; pygidium tear-shaped.

Generic Description
Measurements: Prothorax at widest point 3.2-3.3 mm, elytra at widest point 4.5-4.6 mm, length 10.8-13.3 mm.

Color and vestiture: Head and pronotum dark brown, vestiture of white setae, scutellum dark brown, often densely covered with white setae, elytra golden brown, mottled, often with scattered white setae, ventral surface dark to light brown.

Head: Clypeus coplaner with frons, with anterior angles acute; labrum not coplaner with clypeus, prelabrum visible (M. biguttatus); labium with prementum quadrate, medially grooved; antennae 8-9-segmented, club thin, antennal insertions not visible in dorsal view.

Prothorax: Pronotum chordate or trapezoidal, widest medially, posterior angle acute, posterior margin straight, medially concave or weakly tridentate; coxa transverse; tibia bidentate; pretarsus with claws weakly divergent, equal in length, both claws narrowly split.

Mesothorax: Scutellum broadly triangular or chordate; elytra longer than wide, widest medially, lacking striae, anterior and posterior umbones prominent.

Metathorax: Metathoracic leg with coxa widely separated; femur ovate, narrowing distally; tibia clavate, widest medially, narrowing in distal 1/4th, widening at distal margin, posteroventral distal margin with two large spurs, spurs above tarsal articulation joint, posterior distal margin with deep, broad U-shaped groove; pretarsus with claws similar to prothoracic and mesothoracic claws.

Abdomen: Ventrites 2-4 subequal in length, 5th visible ventrite (=propygidium) length equal to the length of ventrites 3-4 combined, 6th ventrite equal in length to 5th ventrite length, posterior margin with a slight membranous margin, ventrite and sternite of 5th abdominal segment lacking a complete suture; pygidium tear-shaped, longer than wide, narrowing posteriorly, posterior margin blunt.

Notes: This genus is difficult to separate from Ceraspis. Manopus lacks a prothoracic sternum with a posterior margin bearing a medially flattened acuminate process, extending posteriad of the coxae and extending over the mesosternum (characteristic of Ceraspis). As more material becomes available the validity of this genus can be evaluated.
