status

 

Harttiella Boeseman, 1971 View in CoL View at ENA   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 .
