Etymology: Pomacentrus: Greek, poma, -atos = cover, operculum + Greek, kentron = sting (Ref. 45335); yoshii: Named Pomacentrus yoshii in honour of Satoshi Yoshii, who provided the logistic arrangements for the collection of many of the type specimens. The surname Yoshii, which is spelled with a double "i" ending, is treated as a noun in apposition. More on authors: Allen & Randall.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 2 - 22 m (Ref. 54758). Tropical

Western Central Pacific: Known from the southern Marshall Islands at Majuro and Mili Atoll. It was not found in the northern Marshalls at Enewetak Atoll, the site of extensive fieldwork by both authors.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 6.9 cm SL male/unsexed; (Ref. 54758)
Life history characteristics for the family specify that this group is oviparous, with distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 54980; 113699).
