Marsikomerus is a genus of centipedes in the family Schendylidae.

[1][2] Species in this genus are found in Mexico and in the United States (in Arkansas, Texas, and Hawaii).

[3] Centipedes in this genus feature sternal pore-fields that are subcircular or transversally elliptical and found only on the anterior part of the trunk.

The ultimate leg-bearing segment has a single pore on each coxopleuron, a wide metasternite, and legs without claws.

[4] Males of the smallest species in this genus, Marsikomerus arcanus, measure only 10 mm in length and have only 39 leg pairs, the minimum recorded for this genus.
