Comment(s) on data
According to Chace (1997) only 2 species in this genus, M. rhizophorae (Rathbun, 1900), Atlantic species and M. oligodon, Indian O. and Indonesia 'Obviously, further study will be required to determine whether these interesting shrimps that behave like insects belong to one, two or three species'. Additional record in Kenya and distribution of the 2 species in Bruce (1993, Tropical Zoology).
Comment of D. Theuerkauff, collector at Mayotte (29/01/2020) 'Son comportement est vraiment intéressant, je ne l'ai vue que de nuit à la base des racines dans le faciès à Rhizophora … je pense qu'elle est capable de respiration aérienne en tout cas elle se balade librement sur les racines'
