Lord; USNM 372572, 1, Paratype, 70.0 mm SL, Guyana, Rupununi (Region 9), Rupununi River, rock area near Massara, 23 November 2001, col. by D. Arjoon. Diagnosis: Peckoltia cavatica can be identified from all other described Peckoltia except P. braueri by the presence of an orange band in the dorsal fin and by having thin, black lines that outline the plates and bones of the head. Peckoltia cavatica can be identified from P. braueri as above The only other species of Peckoltia similar to P. cavatica in coloration are P. lineola and P. vermiculata, which can be identified by having vermiculations on the dorsal head bones and plates (vs. coloration confined to the borders between bones and plates in P. cavatica). Description: Peckoltia cavatica was recently described by Armbruster and Werneke (2005). Morphometrics in Table 3. Range. Collected from two localities around the Macushi village of Massara near Anai in the Rupununi River (Fig. 8).Published as part of Armbruster, Jonathan W., 2008, The genus Peckoltia with the description of two new species and a reanalysis of the phylogeny of the genera of the Hypostominae (Siluriformes: Loricariidae), pp. 1-76 in Zootaxa 1822 (1) on pages 24-26, DOI: 10.11646/zootaxa.1822.1.1, http://zenodo.org/record/512521
Rhinelepini Armbruster 2004, NEW TRIBE
No full textRHINELEPINI NEW TRIBE <p>Includes:</p> <p> <i>Canthopomus</i> Eigenmann, 1910 (synonym of <i>Pseudorinelepis</i>)</p> <p> <i>Monistiancistrus</i> Fowler, 1939 (synonym of <i>Pseudorinelepis</i>)</p> <p> <i>Pogonopoma</i> Regan, 1904</p> <p> <i>Pogonopomoides</i> Gosline, 1947 (synonym of <i>Pogonopoma</i>)</p> <p> <i>Pseudorinelepis</i> Bleeker, 1862</p> <p> <i>Rhinelepis</i> Valenciennes, 1829</p> <p> <i>Diagnosis:</i> The Rhinelepini is diagnosed by two unique characteristics: an upper pharyngeal tooth plate with a lateral shelf (31: 1) and a large, U-shaped, two-part diverticulum of the digestive tract (211: 1-3). Other characteristics considered synapomorphic for the Rhinelepini are: loss of the second basibranchial (3: 2), interhyal not contacting the cartilaginous section between the hyomandibula and quadrate (26: 0), a long ventromesial process of the palatine (59: 1), a very large, almost square nasal (105: 2), a flattened and widened parasphenoid (106: 1), a loss of ribs behind the enlarged rib of the sixth vertebral centrum (129: 1), at least a partial exposure of the coracoid strut (162: 0), circular (vs. bilobed) pupils, and a straight oesophagus to which the intestine does not pass dorsally (210: 1). See description and diagnosis of the Rhinelepini in Armbruster (1998b) and Quevedo & Reis (2002).</p> <p> <i>Comparisons:</i> The Rhinelepini can be distinguished from <i>Corymbophanes</i> by the lack of a postdorsal ridge of three or more median preadipose plates, and by having five (vs. three) rows of plates on the caudal peduncle, from the Hypostomini and the Pterygoplichthini by having one unbranched and five branched anal-fin rays (vs. one unbranched and four branched rays) and by lacking the dorsal flap of the iris, and from the Ancistrini and the Pterygoplichthini by lacking highly evertible cheek plates.</p>Published as part of <i>Armbruster, Jonathan W., 2004, Phylogenetic relationships of the suckermouth armoured catfishes (Loricariidae) with emphasis on the Hypostominae and the Ancistrinae, pp. 1-80 in Zoological Journal of the Linnean Society 141 (1)</i> on pages 61-62, DOI: 10.1111/j.1096-3642.2004.00109.x, <a href="http://zenodo.org/record/5429286">http://zenodo.org/record/5429286</a>
