Aegla odebrechtii Müller, 1876  

Diagnosis.—Antero-lateral spine of carapace reaching middle of cornea; protogastric lobes obsolete; rostrum of medium length in adult males, deflected and slightly recurved distally, without carina on distal third; anterior angle of ventral margin of epimeron 2 unarmed; proximal outer margin of movable finger of cheliped with lobe tipped with tubercles; palmar crest of cheliped subdisciform, excavated; inner margin of ventral surface of ischium of cheliped with one distal conical spine, one proximal smaller spine, and up to three tubercles between them.

Formerly Known Distribution.—Brazil: The majority of records refer to the central region of the state of Santa Catarina, and the northern part of Rio Grande do Sul. In the Rio Itajaí basin, there is only the record of the holotype described from the Rio Itajaí-Açu, municipality of Blumenau.

New Records.— Brazil: Santa Catarina: Rio Itajaí basin, a tributary of the Rio Itajaí do Sul ( Fig. 1 View Fig ), Atalanta, 16.viii.1999, G. Bond-Buckup and L. Buckup col., 7 m, 2 f, 3 j ( UFRGS 2676 )   ; Ribeirão Belchior, a tributary of Rio Itajaí-Açu , Gaspar, 14.vi. 1986, Ada Silva col., 3 m, 2 f ( UFRGS 2390 )   .

Biology.—Unknown.

Remarks.—The phylogeny of the group, presented by Pérez-Losada et al. (2004), showed that A. odebrechtii   belongs to clade C, with A. jarai   as the sister species, and a divergence time estimated at 33.2 ± 1.8 MYA.
