Description. Length 1.30 mm; width 1.03 mm; depth 0.73 mm. Body highly convex. Color black throughout, tarsi and funicle pale. Head transverse. Punctures of head and pronotum smaller in size than eye facets, not impressed and separated by interpunctural spaces about equal to width of 1–4 punctures; those of elytron not similar to those of pronotum, separated by a space of 2–4 punctures. Antennal segmentation similar to M. lundgreni with funicle composed of small antennomeres and a club of elongate and flattened antennomeres. Antennal club about half length of entire antenna. Sub­basal punctate line of pronotum deeply impressed. Setae present on edge of elytron above epipleuron; length of middle setae about equal to length of tarsomere III; edge of epipleuron not visible in dorsal view. Umbo well developed.

Type Material.

Holotype, Sex Unknown. With labels as follow: Holotype [round label bordered with a red circle], sp. figured; Purula Vera Paz.; 1911­403; Micropsephodes serraticornis Ch. [hand written]; Tr. Ent. Soc. L. 1913 det. by Champion. The specimen is from Guatemala and is deposited in the Natural History Museum, London ( BMNH) .

Comments. The single specimen of M. serraticornis is in relatively good shape. However, the left antenna, right middle leg, and maxillary palpomere are disarticulated lying separately from the body on the card, and two legs are missing from the left side. We did not remove this specimen from its card because of the risk of losing parts. As is, the specimen serves as an appropriate type specimen for the genus. Specimens of undescribed species from the Dominican Republic and Ecuador differ from M. serricornis by having welldeveloped flabellate antennae and the head not transverse.
