Systematics
In a detailed morphological study of Mugilogobius and allied genera Larson (2001) placed Caecogobius in the subfamily Gobionellinae and the Mugilogobius clade. She also provided a revised diagnosis of the genus and a drawing of the head of paratype CMK 7249 (which is ZSM 27189 on loan to CMK). Caecogobius appears to be close to Tamanka siitensis, a freshwater goby from two crater lakes on Jolo Island, Sulu Archipelago, Philippines, and the two may share a common ancestor. The Sulu Archipelago is directly south east of Mindanao Island and it is very likely that they formed a common landmass at lowered sea level.
Kuang et al. (2018) used molecular markers to study the internal structure of the Suborder Gobioidei which contains within it eleven Families. They demonstrated that Milyeringidae is sister Family to a group of four Families: Oxudercidae+Gobiidae+Butidae+ Eleotridae and is only disttantly related to four others: Odontobutidae, Rhyacichthyidae, Apogonidae and Kurtidae (samples from Thalasseleotridae and Trichonotidae were not availabe for analysis).
