Description.

Body length: 1.28-1.38 mm, width: 0.84-1.10 mm. Color blackish with light bluish luster. Ventral side and appendages light brown or amber. Distance between eyes about 2 times wider than transverse diameter of eye. Diameter of punctures on vertex smaller than distance between them. Pronotal punctures sparse, slightly elongate in shape, their transverse diameter much smaller than distance between them. Elytral punctures relatively large, forming well developed rows. Distance between punctures in rows about as great as their diameter. Distance between rows much greater than diameter of punctures. Lateral (outer) side of metatibia deeply and coarsely dentate. Metatibial spur curved, nearly as long as denticle situated on apex of inner side of metatibia. Posterior sclerotizations of vaginal palpi nearly parallel-sided, straight at apex. Posterior sclerotization of tignum gradually widening posteriorly, abdominal sternite 8 with two sclerotized spots near apex. Spermatheca with relatively long middle part of receptacle, with internal side forming nearly 90 degree angle.

Comments.

Monotalla dominica can be separated from other Monotalla by its short metatibial spur situated on the apex of the inner side of the metatibia that barely projects beyond apicomedial denticle.

Etymology.

This species is named after the island where it occurs.
