Morphological differences between the eastern Pacific gobiid fishes Quietula guaymasiae and Quietula y-cauda (Teleostei: Gobiidae) with emphasis on the topography of the lateral line system Harald AHNELT & Josef GÖSCHL (1) (1) University

- Quietula guaymasiae and Quietula y-cauda occur sympatrically
in the Gulf of California (Mexico). Both species are similar in their
meristic values but differ in the topography of the lateral line system:
the pattern of free neuromasts, their total number and their number in
most rows. Quietula guaymasiae is generally somewhat larger than
Quietula y-cauda but differences in the number of neuromasts between
both species are not size dependent, and the neuromast pattern does not
vary between juveniles and adults of either species. The lateral line
system of Quietula guaymasiae and Quietula y-cauda is described
in detail. For identification of the neuromast pattern and for the comparability
of this feature with other gobiids, a nomenclature of the series and the
rows of free neuromasts is given. |
