This species has more of a
slender body than any other member of this genera
and the ventral fins are very large. They posses a
reticulated design on the head and pectoral fins.
Description: Pseudohemiodon almendarizi
can be distinguished from all its congeners by the
combinations of the following characters: abdomen
totally covered with small to medium-sized, irregularly
shaped plates (vs. abdomen partially covered, in P.
and P. amazonum or covered by one central
row of plates wide and rectangular, in P. thorectes);
absence of small, bony plates, anterior to gill openings
(vs. presence of one to three small plates in front
of the gill openings, in P. lamina); 12–15
coalescing lateral scutes (vs. 20–21 in P.
thorectes); thoracic plates (between pectoral
and pelvic fins) fold sideways (vs. thoracic plates
do not fold in P. amazonum); eyes relatively
smaller, its diameter without notch fits 12.0–12.7
times in HL (vs. 8.3–11.8 times in HL in P.
times in HL in P. lamina, 8.2–8.7 times
in HL in P.
laticeps and 8.1–9.2 times
in HL in P. unillano); body less wide at
anal-fin origin 10.4%–12.0% SL (vs. 13.4%–17.7%
SL in P apithanos, 12.8%–13.9% SL in P. laticeps,
11.9%–17.1% SL in P. unillano); six or seven
wide and dark transverse bands, posterior to dorsal-fin
(vs. bands absent in P. laticeps, P.
unillano, and medium to large sized P. lamina
(over 60 mm SL) or no more than three or four transverse
dark bands posterior to dorsal-fin in P. apithanos,
or up to eight in very small sized (below 55 mm SL)
of P. lamina (Provenzano-Rizzi et. al 2022).
Sexual Differences: Mature males
will develop their lower lips to allow them to carry
their eggs (abdomino-lip brooders). The very large
eggs are incubated by the male. Aquarium Care:
Requires a large aquarium witha big surface area.
Prefers a sand substrate as they like to dig. Diet:
Algae wafers, sinking tablet and frozen foods such
as bloodworm and shrimp. Etymology:
The specific name honours Ana de Lourdes Almendáriz,
in recognition of her significant contributions to
the Ecuador herpetofauna knowledge, and her enthusiasm
and friendship for many years. Noun in apposition.
Aguarico River, near Puerto Loja, Napo River system,
Amazon River Basin, approx. 00°52’57”S
