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.
