Trilepida Hedges (type species: Stenostoma macrolepis Peters 1858) |
Contents:
16 species, of which 14 (87.5%) are endemic.
Endemism: 0%  100%
Remarks:
Includes the species affinis, formerly assigned to the genus
Rena,
and the species acutirostris, formerly assigned to the genus
Siagonodon.
For a short period, the genus name
Tricheilostoma was used for the species now placed in Trilepida, until Hedges (2011) resolved the taxonomic confusion regarding the type species of the former genus.
Tricheilostoma is now used for the African species previously assigned to Guinea (a preoccupied, thus unavailable name for these species).
Distribution:
S. Central America, N. South America.

|
| |
Trilepida affinis Mumaw, González & Fernández 2015 |
Remarks:
Previously assigned to the genus
Rena (e.g., Adalsteinsson, Branch, Trape, Vitt & Hedges 2009).
Wallach, Williams & Boundy (2014) listed this taxon as a synonym of Trilepida macrolepis, based on Pinto (2010), however, the authors omitted this reference
in their literature list, so the synonymization has not been verifiable.
It is now regarded as a valid species (e.g., Mumaw, González & Fernández 2015; Pinto & Fernandes 2017).
The type specimen was collected in Tachira state in Venezuela, but the exact locality is unknown (Pinto & Fernandes 2017).
The range map shows the approximate location.
Distribution:
Venezuela.

|
| |
Trilepida dimidiata (new combination, this work) |
Remarks:
When they moved dimidiata from
Rena to
Tricheilostoma, Pinto & Fernandes (2012) were apparently unaware of Hedges' (2011) reassignment to Trilepida of all South American species previously placed in
Tricheilostoma. The latter genus is now restricted to African species.
Records from Minas Gerais (e.g., Silveira, Pires & Cotta 2004; Passos, Caramaschi & Pinto 2006; São-Pedro & Pires 2009) refer to jani (Pinto & Fernandes 2012).
Distribution:

Remarks:
Pinto & Fernandes (2017) did not include any records from eastern Brazil for this species. Consequently, records from Bahia (Argôlo 2004), Espirito Santo (Ruschi 1966), and Rio de Janeiro (Rocha, Bergallo, Pombal, Geise, Sluys, Fernandes & Caramaschi 2004) are regarded as doubtful.
