Smilosicyopus fehlmanni (Parenti & Maciolek 1993)

More Info


Pauls Pocket Creek, northern Queensland. Elsewhere the species occurs in the tropical, west-central Pacific. 
Inhabits fast-flowing streams from teh source to the lower reaches, often in areas with rocky substrates. After hatching, the larvae are washed downstream, and develop in estuaries or marine environments before migrating back to freshwaters.


Gravid females have a bright, blood-red belly; juvenile females may have an orangish belly. Belly in adult males light brown or reddish brown. In both sexes, the anterior portion of the pelvic frenum may be deep russet or the same pale tan as the remainder of the pelvic disc. This russet color appears most frequently in the barred and more heavily pigmented specimens.


The species is named in honour of Herman Adair Fehlmann who participated in collection of the type specimens and recognized the species as new.
