Etymology: luticolus: The species name is derived from the Latin word for mud, lutus, and the verb colere, to dwell, referring to the habitat in which the new species was collected; a noun in apposition (Ref. 116049).

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Diagnosis: Monopterus luticolus is assigned to the 'Amphipnous group' within the genus Monopterus based on the presence of a unique synapomorphy of the group: the spatial dissociation of ceratobranchial 1 from hypobranchial 1 and its close association with hypobranchial 2 and ceratobranchial 2 (Ref. 116049). It is distinguished from all other species of synbranchids, including the other African synbranchids Ophisternon afrum and Monopterus boueti, by having more vertebrae, 198-208 vs. 100-194 (Ref. 116049). It is further distinguished from all synbranchids except O. infernale, O. candidum, M. boueti, M. eapeni, M. roseni, and M. digressus by the lack of externally visible eyes; Monopterus luticolus is also readily distinguished further from the African synbranchid species O. afrum by having the posttemporal greatly reduced in size and removed spatially from the supracleithrum and cleithrum, as well as from the skull, vs. posttemporal large, articulating with supracleithrum and epiotic of skull; and by having five vs. six branchiostegal rays (Ref. 116049). Monopterus luticolus is most similar to the West African M. boueti, from which it differs by having fewer abdominal vertebrae, 95-101 vs. 108, and more caudal vertebrae, 98-110 vs. 79-86; it differs further from M. boueti by several osteological characters (Ref. 116049).
Body shape (shape guide): eel-like.
Obligate air-breathing (Ref. 126274); This species was found during attempts to collect caecilian amphibians; they were dug from moist to wet soil, usually inundated by the neighbouring water body; the sites were immediately adjacent to both lotic and lentic aquatic habitats (Ref. 116049).
