Max length : 5.5 cm TL mâle / non sexé; (Ref. 31267); common length : 4.5 cm TL mâle / non sexé; (Ref. 27139)
Rayons mous dorsaux (Total) : 8 - 9; Rayons mous anaux: 20 - 25. Distinguished from all other members of the genus by the combination of the following characters: 41-47 vertical rows of scales; 8-9 dorsal rays; 20-25 anal rays; and the distinctive color pattern of males (Ref. 26687).
