Description
In life Dichotomyctere kretamensis is olive green in color dorsally and laterally with round and oblong spots of varying sizes. Most specimens exhibit a black occipital chevron and a partially interrupted ventro-lateral black stripe running from the mouth below the eye and the pectoral fin that fades as it extends back to the vent. The ventral surface otherwise is white. Fins are unmarked and the caudal fin (tail) is dusky. Based on the few specimens that have been measured, this fish has a maximum length of 4.5 centimetres (1.8 in).
