Description.

Body length: 1.18-1.25 mm, width: 0.91-0.77 mm. Elytra with blackish and bluish luster. Ventral side and appendages light brown or amber. Distance between eyes about 1.4-1.5 times wider than transverse diameter of eye. Punctures on vertex well defined, sparse, smaller than distance between them. Pronotal punctures sparse, slightly elongate in shape, their transverse diameter much smaller than distance between them. Elytral punctures larger than those on pronotum, forming rows. Distance between punctures in rows smaller than or as great as their diameter. Distance between rows greater than diameter of punctures. Lateral side of metatibia with short evenly spaced denticles. Metatibial spur curved, projecting beyond denticle situated on apex of inner side of metatibia. Posterior sclerotizations of vaginal palpi with slightly sinusoidal lateral side, straight at apex. Tignum more or less parallel sided, abdominal sternite 8 without sclerotized spots near apex. Spermatheca with relatively long middle part of receptacle, with internal side slightly bend.

Comments.

Monotalla obrienorum can be separated from all other Monotalla species based on the distance between eyes being 1.40-1.50 times greater than the transverse diameter of the eye.

Etymology.

We name this species after Charles W. & Lois B. O’Brien who collected two of five new species described in this paper.
