Harttiella Boeseman, 1971
status

 

Harttiella Boeseman, 1971  ZBK  .

Type species: Harttia crassicauda Boeseman, 1953  ZBK  .

Holotype: RMNH 19418, Surinam, in a creek of the Nassau Mountains, Marowijne River drainage . 

Gender: feminine.

This monotypic genus is only known from its type locality. The single species was collected in a little forest creek over sandy and rocky bottoms (Boeseman 1971). Sexual dimorphism is similar to that of Harttia  ZBK  , in which mature males develop hypertrophied odontodes on the pectoral spines, along the margin of the snout, and on the entire body except for the abdominal region. The phylogenetic position of Harttiella  ZBK  remains uncertain. Boeseman (1971), and Isbrücker (1981a) gave it a rather basal position within Loricariinae  but its geographic isolation in the Marowijne drainage could also correspond to a more derived state within Harttiini  . The morphology of Harttiella  ZBK  suggests it is a dwarf form closely related to Harttia  ZBK  . Rapp Py-Daniel (1997) tentatively placed Harttiella  ZBK  within Harttiina  because of its close resemblance with Harttia  ZBK  . Unfortunately, this question may remain unresolved as Mol & Ouboter (2004) mentioned the possible disappearance of this species because of mining activities in the Nassau Mountains. This species is also interesting because of its morphological convergence with Ixinandria  ZBK  , a genus within Loricariini  found in the southwestern part of the continent. The morphological likeness between Ixinandria  ZBK  and Harttiella  ZBK  may have misled Boeseman (1971) when he moved Canthopomus montebelloi Fowler, 1940  ZBK  into Harttiella  ZBK  .
