Etymology: Dorosoma: Greek, doris = lance + Greek, soma = body (Ref. 45335). More on author: Hubbs.

Anal
soft rays: 22 - 29. Body moderately deep; belly with 15 to 18 + 9 to 12 scutes. Mouth small. Last dorsal fin ray long, but less the distance from snout tip to pelvic fin base; anal fin relatively short. Scales somewhat small, somewhat irregular. A dark spot behind gill opening. Distinguished from Opisthonema species by its anal fin which is longer than head and well behind dorsal fin base.
North America: Pacific drainage of northwestern Mexico (Río Piaxtla, Río del Fuerte, Río Sinaloa system, Río de Mocorito, Río Muerto, Río Yaqui system, i.e. between Sinaloa and Sonora).
Occurs in rivers and perhaps in lakes. A filter-feeder, its feeding and breeding habits presumably similar to other Dorosoma species. More data needed.
