877387B8017A861DFF5EDFB7FBFEB088.taxon	description	This species is known only from the illustration provided by Valenciennes. So far no type material could be found in collections nor does the figure resemble clearly any known species. As long as H. itacua cannot be assigned to any other taxon as a senior synonym it should be considered uncertain, thus valid.	en	Koerber, Stefan, Weber, Claude (2014): The Hypostominae (Siluriformes: Loricariidae) of Argentina.

(2003) Hypostomus latifrons Weber, 1996 synonym: Peckoltia vittata NON Steindachner, 1881 type locality: Paraguay, Río Aguaray-guazú, Río Paraguay basin, River Paraná system One lot of paratypes is from the Río Paraguay where it forms the political border between Paraguay and Argentina (Ita Enramada, 11 km S of Asuncion). first record: Meinken (1937) from Río Paraná in Corrientes sub Ancistrus vittatus other records: sub Peckoltia vittata: - Rodriguez & Cuello (2005): Corrientes, Rio Paraná at Corza-Cué | Corrientes, río Paraná at Puerto Yahape | Santa Fe, tributary of río Paraná near city of Santa Fe sub Hypostomus latifrons: - MHNG 2582.052: Corrientes, Rio Paraná at Corza-Cué - Bishop & Bishop (2004): Entre Rios, Rio Paraná at city of Paraná sub Hypostomus sp.: - Almirón et al. (2008): Parque Nacional Pre-Delta, several locations remarks: The specimen in MHNG 2582.052 was identified as H. latifrons in 1996 but this, for being unpublished data, could not be considered to indicate a distrbution in Argentina in the CLOFFSCA account of this species (Weber 2003). This was the first time that a collection lot with a locality from Argentina has been determined as H. latifrons. Meinken’s Ancistrus vittatus still exists (ZMB 32513, coll. C. Hahn, Corrientes, im Río Paraná, det. H. Meinken, Dez. 1936) and could without doubt be determined as a juvenile Hypostomus latifrons. Loricariid specialists in the aquarium hobby have established a system of Lnumbers to provide working names to unidentified loricariid species that have been imported for aquarium purposes (Stawikowski et al., 2004). A loricariid species imported from Paraguay had been assigned L 51 (Lucas & Mahr, 1989) and was later determined as H. latifrons (Stawikowski et al., 2004). Another species from Paraguay initially thought to be either a Peckoltia sp. or a species from the Panaque - dentex - complex was presented as L 281 (Werner, 2000) and later also determined as a juvenile of L 51 (Stawikowski et al., 2004). Animals of Hypostomus latifrons in an import of aquarium fishes from Paraguay with mixed sizes, showed during their growth that the species starts changing the colour pattern between 70 and 80 mm, losing the typical honeycomb drawings and part of the reddish colour (figs. 2 - 4.). Reaching 100 mm they finish the changing and then show the colour pattern of adults (Ingo Seidel, pers. com. 25.09.06). Adult H. latifrons are reported to reach 287 mm (longest specimen in type series, Weber, 1986) and 250 - 300 mm (Seidel & Evers, 2005). All specimens reported so far from Argentina have been not larger than 51 mm (Meinken, 1937) or max. 55.4 mm (Rodriguez & Cuello, 2005). The records of Peckoltia vittata from Argentina, all originally based on either Meinken (1937) or Rodriguez & Cuello (2005), represent juvenile H. latifrons. All the above shall finally put an end to the myth of Peckoltia species in the La- Plata-basin.	en	Koerber, Stefan, Weber, Claude (2014): The Hypostominae (Siluriformes: Loricariidae) of Argentina.

Weber (2003) restricted the distribution of H. paulinus to the Tietê river basin in Brazil and findings in Paraguay. Weber (1986, unpublished degree thesis) listed one lot (MHNG 2198.44 - 45) from the río Tembey in Southeast Paraguay, only few km from the Argentinean coast of the río Paraná. Although possibly still doubtful, we currently consider this species to exist in Argentina and future records may confirm this Southern distribution.	en	Koerber, Stefan, Weber, Claude (2014): The Hypostominae (Siluriformes: Loricariidae) of Argentina.

877387B8017E8619FF5EDD90FDC7B590.taxon	materials_examined	other records: Roa & Permingeat (1999) remarks: Berg (1895) considered Perugia’s Plecostomus punctatus partially as a synonym of both, P. commersonii and of P. commersonii affinis. He also put Plecostomus cordovae Günther and P. paranensis Weyenbergh in the synonymy of P. commersonii affinis. López (1992) treated Berg’s P. commersonii affinis as a synonym of H. cordovae. Therefor it could be assumed that the alleged first record for H. punctatus sub P. commersonii affinis, as listed by López et al. (2003), might have referred to H. paranensis. From the 11 species of Hypostomus treated by López & Miquelarena (1991) and López (1992), Hypostomus punctatus is the only one without reference to examined material, thus indicating a doubtful situation regarding a distribution in Argentina. Weber (2003) limited the distribution of H. punctatus to the Southeastern Brazilian coastal drainages.	en	Koerber, Stefan, Weber, Claude (2014): The Hypostominae (Siluriformes: Loricariidae) of Argentina.
