A genus of relatively small banjo catfishes (less than 80 mm SL) distinguished from other aspredinids by having the following unique characters: the dentary teeth are restricted to broad tooth patch near symphysis of lower jaw (Fig. 1) (vs. more broadly distributed along the length of the dentary); the metapterygoid lacks a bony connection with the quadrate (Fig. 1); the posterior end of autopalatine is distinctly forked and bears two separate terminal cartilages (Fig. 2); the absence of the fourth pharyngobranchial; the absence of gill rakers on all branchial arches; and the lack of bifid hemal spines on vertebrae that articulate with anal-fin pterygiophores.</p><p>Other characters not unique to this genus, but still useful for distinguishing it from other aspredinid genera include: the anterior limits of upper and lower jaws are approximately equal (also in Acanthobunocephalus); the lateral line is truncated at approximately the level of the dorsal-fin origin (also in Acanthobunocephalus); the dorsal- and ventral-most principal caudal rays much shorter in length than other principal caudal rays (also in Acanthobunocephalus); the dorsal- and anal-fin membranes are not adnate with body (also in Acanthobunocephalus); the interhyal is absent (also in Hoplomyzon); and the abdominal and precaudal centra lack bony horizontal lamina (also in Dupouyichthys, Ernstichthys, Hoplomyzon and Micromyzon).</p><p>Etymology. The generic name is a combination of the Greek word pseudes, meaning false or deceptive, plus the aspredinid genus Bunocephalus . It alludes to the fact that members of this new genus have previously been mistaken for juveniles of various species of Bunocephalus .</p><p>Key to species of Pseudobunocephalus .</p><p>1a.

Pseudobunocephalus lundbergi can be distinguished from all congeners by having the following unique characters within the genus: dorsal surface of skull ornamented with numerous bony knobs of equal size (Fig. 4); distinct anterior and posterior cranial fontanels separated by a bony epiphyseal bar formed between the frontals (Fig. 3); infraorbital canal exits from the sphenotic (Fig. 3) and extends anteriorly past eye, bearing up to four pores (not figured); premaxilla without a posterolateral limb; and fifth centra with posteriorly directed processes that articulate with skeletal elements of the dorsal fin.</p><p>Description. Dorsal, lateral and ventral views in Fig. 4 illustrate body shape and positions of fins and barbels. Morphometric and meristic data for holotype (ANSP 168817) and 10 syntopic paratypes (ANSP 172504) are summarized in Table 1. Head depressed with only slight depression between orbits. Skull ornamentation well developed with paired series of bony knobs beginning behind eyes, converging on occiput and continuing on dorsal lamina of Weberian complex and middle nuchal plate. All bony knobs approximately equal in size. Anterior and posterior cranial fontanels present and separated by bony epiphyseal bar formed by frontals (Fig. 3). Integument covered with small unculiferous tubercles, those on posterior body in longitudinal rows; mid-dorsal row well defined; 2-3 well-defined rows on each side of caudal peduncle; several poorly-defined rows ventrally (Fig. 4). Caudal peduncle slender, round in cross section, tapering to caudal fin.</p><p>Mouth terminal, anterior limits of upper and lower jaws approximately equal. Premaxilla with 5-6 rows of acicular teeth and lacks posterolateral process. Dentary with 12-15 rows of teeth restricted to patch near symphysis of lower jaw (Fig. 1). Anterior nostril tubular, located at tip of snout, projecting beyond upper lip. Posterior nostril simple without flap or barbel, opening anteromedial to eye. Eye without free orbital rim. All barbels simple, unbranched; maxillary barbel reaching pectoral spine insertion. Posterolateral mental barbel at least twice as long as anteromedial mental barbel. Gular fold absent, branchiostegal membranes united to each other and to isthmus, 5 branchiostegal rays (Fig. 1). Opercular opening reduced to small valvular slit on ventral surface just anterior to pectoral spine insertion.</p><p>Gill rakers absent on all branchial arches. Pharyngeal teeth well developed on upper tooth plate; 1 or 2 rows of teeth on lower tooth plates. First and second hypobranchials well ossified; fourth pharyngobranchials absent. Parurohyal triangular with slight dorsal keel.</p><p>Openings of sensory canals on head darkly pigmented. Infraorbital canal exits sphenotic (Fig. 3) and passes anteriorly beyond eye, bearing up to four pores (not figured). Lateral-line canal truncated just posterior of parapophyses of fifth vertebra and anterior to dorsal-fin origin. A few individual isolated pores scattered more posteriorly, but never connected to main lateral-line canal.</p><p>Dorsal fin without spinelet; consists of relatively flexible spine and four soft rays. Dorsal-fin membrane not adnate with body. Anterior nuchal plate and supraneural absent. Middle nuchal plate ornamented with a single bony knob. Adipose fin absent. Anal fin with 5-7 soft rays (6 in holotype), anal-fin membrane not adnate with body. Pectoral fin with robust spine and 5 soft rays. Shaft of pectoral spine curved with serrations along both pre-axial and post-axial margins. Intact pectoral spine with flexible tip. Axial pore present. Postcoracoid process of pectoral girdle extends slightly past postcleithral process in lateral view. Pelvic fin with 6 soft rays, second and third rays longest, not reaching anal-fin origin, no pelvic splint. Caudal fin with 10 principal rays plus one upper and one lower procurrent ray. Caudal-fin margin rounded with outermost principal rays unbranched and shorter than branched principal rays.</p><p>Total vertebrae 33-34 (34 in holotype). Vertebrae 6-9 bearing ribs; dorsal-fin pterygiophores associated with Weberian complex (vertebrae 1-5) and vertebrae 6-11. Dorsal lamina of Weberian complex ornamented with series of three bony knobs. Parapophyses of fourth vertebra form broad lamina over swim bladder. Parapophysis of fifth vertebra long, curved anteriorly and extended laterally to body surface. Parapophyses of fourth and fifth vertebrae separated by deep notch (Fig. 3). No horizontal bony lamina developed on precaudal, caudal or ural centra. Hemal spines simple, not bifid, on vertebrae articulating with anal-fin pterygiophores.</p><p>Color in alcohol. Pigmentation variable with two distinct color morphs, one dark (Fig. 4) and one light. Dark morph with head light brown and irregularly mottled with darker pigment; overall body light brown with three poorly defined dark saddles, first beneath dorsal fin, and two more on posterior body. Individual unculiferous tubercles may be unpigmented or darkly pigmented giving speckled appearance to body. Ventral surface light brown with dark pigment concentrated in unculiferous tubercles. All fins and barbels mottled with dark pigment. Light morphs have similar pigmentation pattern to dark morphs but lack series of dark saddles on dorsal surface.</p><p>Size and sexual dimorphism. Specimens range from 19.5-30.0 mm SL. The largest specimens examined are females with ripening ova (0.5 mm in diameter). No observed dimorphism of body ornamentation, fins or pigmentation.</p><p>Distribution. Pseudobunocephalus lundbergi is currently known from just a few localities in the lower río Caura (type locality), upper río Apure, and río Meta (Fig. 5), but is likely more widely distributed within the río Orinoco basin of Colombia and Venezuela.</p><p>Etymology. The specific name is patronymic in honor of Dr. John G. Lundberg of The Academy of Natural Sciences of Philadelphia. Lundberg served as the author’s Ph.D. advisor, and has made numerous contributions to the field of Neotropical ichthyology and the systematics of siluriform and gymnotiform fishes.</p></div>	https://treatment.plazi.org/id/061E87A118698569FF41F998FC12FCC2	Public Domain	No known copyright restrictions apply.
