Etymology: Pempheris: Greek, pempheris = the name of a fish (Ref. 45335);  adusta: Name from Latin 'flavi' meaning yellow, and 'cycla' for ring, referring to the bright yellow ring encircling the pupil, which is often still apparent in recently preserved specimens..
  More on author: Bleeker.

Issue
Pempheris flavicycla flavicycla was considered as synonym of P. adusta by Koeda et al., 2014 (Ref. 95675) but valid according to Randall et al., 2014 (Ref.95583); and Pempheris flavicycla marisrubri as synonym of P. erythraea in Golani et al., 2018 Ref. 120578. Please send references, or more studies are needed.

Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 6; Raggi dorsali molli (totale) : 8 - 10; Spine anali: 3; Raggi anali molli: 36 - 45; Vertebre: 25. This species is distinguished by the following characters: pectoral fin base with a faint blackish spot; pored lateral-line scales 56-64 (Andaman Sea 52-58; Pacific 51-62); scale rows above lateral line 4.5-6.5 (usually 5.5; Andaman Sea and the Pacific Ocean, 4.5-5.5, usually 4.5); circumpeduncular scales 14-18 (usually 16); outer edge of anal fin with a distinct blackish band (rarely faint or only anterior half prominent; usually none in Pacific); posterior edge of caudal fin with a blackish band (caudal fin whole yellowish in Andaman Sea); upper-jaw length 14.2-15.6% SL; body depth 41.4-45.4% SL. Individuals in the Pacific are distinguished from its congeners by the following set of characters: ctenoid and deciduous scales are thin and semicircular in shape; 51-62 pored lateral-line scales; 4.5-5.5 (usually 4.5) scale rows above lateral line; pectoral fin base with a faint blackish spot; anal fin usually have no blackish outer margin; anal fin base with a dusky band (Ref. 95675).

Biologia     Glossario (es. epibenthic)

This fish is common on coral reefs (Ref. 6645); forming aggregations in caves or crevices or under overhangs (Ref. 48636) by day, but a few may at times be seen in the open, close to the shelter of reefs. This species is also observed forming small groups with Myripristis murdjan at 0.5-1 m below the surface. At night, it is known to feed on zooplankton (Ref. 94773). Spawning occur during April to June, and is year-round in Okinawa I. (Koeda et al., in press - in Ref. 95675). Spawning occurred after sunset with individuals larger than 11 cm SL joining the spawning group (Ref. 95675). Flesh is edible (Ref. 12484).
