Brazil
; Recent.
Remarks.
Diagnosis follows
Witte (1993)
. The observed specimen differs from the
holotype
in general size and shape of the ventral carina, possibly representing a juvenile form of the species. Specimens identified as
Triebelina
cf.
raripila
(
Müller, 1894
)
in
Keyser & Schöning (2000)
are similar to
T. intermedia
, despite their short average length. Comparing the literature for both species (
Müller 1894
;
Yassini 1979
;
Jellinek 1993
;
Witte 1993
;
Szczechura 1998
), it is possible to separate them based on the more subrectangular general shape and well-developed ventral carina of
T. intermedia
when compared to
T. raripila
.
