Given the L-number of L168
before description. Description:
The Dekeyseria genera possess broad and flattened
heads. Both sexes have odontodes to the pectoral and
caudal spines with the males being somewhat longer.
Some authors (Seidel 2008) place the Dekeyseria
genus as Zonancistrus and state these species
as being in the Dekeyseria brachyura group.
Aquarium Care: Whatever their true
placing's they are relatively easy to keep in the
aquarium. If you keep them in soft acid water they
will sport their natural colours as seen in the supplied
images. If the water is too hard their colours will
be somewhat muted and they will take on a fright pattern.
Omnivorous, veg, tablet and fine frozen foods. Remarks:
A re-evaluation of Dekeyseria brachyura and
D. pulchra found them to be junior synonyms
of D. picta, the oldest species among these
congeners, based on continuous intraspecific variation
in morphometrics and colour pattern. Examination of
material deposited at Brazilian and Venezuelan collections,
including the original type specimens of Ancistrus
brachyurus and A. pictus, plus samples
recently collected in the Rio Negro, Amazonas, Brazil,
allowed re-evaluation of the taxonomic status of D.
picta and provides additional information on
its distribution, habitats and reproductive strategies
(R. Silva et al 2018).
