Type locality.
"Rio Napo, northeastern boundary of Ecuador".
Type material.
ANSP 227455 (1), possible syntype.
Diagnosis.
Shell relatively medium-sized, with longitudinal streaks reddish-brown dots, some dots irregularly spaced in between, sculptured with a regular pattern of granulation (Fig. 5B), suture somewhat descending in front, rapidly descending behind the lip, aperture ovate, peristome hardly expanded and reflexed.
Dimensions.
Shell height 56.8, diameter 29.5 mm.
Distribution.
Ecuador, Prov. Napo,
Rio
Jatunyacu [=
Rio
Napo].
Ecoregion.
Eastern Cordillera real montane forests [NT0121].
Remarks.
This taxon has been considered as a separate species. Upon comparing the type with material of
Plekocheilus (Eurytus) piperitus
(Sowerby I, 1837), we conclude that
mcgyntyi
is very similar and consider it herein as subspecies of
Sowerby's
taxon (stat. n.). The differences seem to consist mainly in
Plekocheilus (Eurytus) piperitus mcgyntyi
having a more expanding lip, and a somewhat slenderer shell. The Ecuadorian material mentioned by
Borrero and Breure (2011)
is now tentatively considered to be this subspecies.
