A taxonomic revision of the Neotropical electric fish genus Brachyhypopomus Ostariophysi: Hypopomidaewith descriptions cht 15 new species. William G. Crampton 1. Carlos D. Joseph C. Waddell 1. Nathan R. Lovejoy 3. WGRC crampton ucf. Brachyhypopomus cannot be diagnosed unambiguously from Microsternarchus or from Procerusternarchus on the basis of external characters alone.
Brachyhypopomus comprises 28 species. Here we describe 15 new Sinks grove WV cheating wives, and provide redescriptions of all 13 previously described species, based on Sbeastiao, morphometric, and other morphological characters.
We include notes on ecology and natural history for each species, and Live chat sex Arrozal De Sao Sebastiao regional dichotomous keys and distribution maps, based on the examination of 12, specimens from 2, museum lots.
Brachyhypopomus species are abundant in shallow lentic and slow-flowing freshwater habitats from southern Costa Rica and northern Venezuela to Uruguay and northern Argentina.Lunch Fuck Sex Girl
Species diversity is highest in Greater Amazonia, Live chat sex Arrozal De Sao Sebastiao 20 species occur: Two species occur in small Atlantic drainages of southern Live chat sex Arrozal De Sao Sebastiao Three species occur in trans-Andean drainages: Biogeography; Bluntnose knifefish; Electroreception; Identification key; Rhamphichthyoidea.
Brachyhypopomus species, zex in Table 1are small to medium-sized, cryptically pigmented, and Srbastiao active predators of aquatic invertebrates.
The genus is conspicuously absent from the bottoms of deep river channels Crampton, Brachyhypopomus and other small hypopomids are not exploited as food fish, but they sometimes feature in the diet of Amerindians Ellis,and are occasionally exported as ornamental fish Chao, Like all gymnotiform fish, Brachyhypopomus generate electric organ Castle Shannon Pennsylvania girls sex cams EODswhich, in combination with a cutaneous array of tuberous electroreceptors, facilitate active electrolocation and electrocommunication Bullock et Segastiao.
Crampton et al. The 15 species described herein are in bold. Name-bearing type refers to the holotype except for lectotype LTor syntypes ST. Thenceforth and untilfive additional species of Brachyhypopomus were described: These were Wanted boat bitch assigned to the genus Hypopomuswhich was erected earlier by Gill ; see 'Taxonomic remarks' in the generic redescription herein.
Mago-Leccia divided Hypopomus sensu Gill into two genera: Hypopomusand a new genus Brachyhypopomus. Hypopomus was restricted to Hypopomus artedi Arroxal, and its now junior synonym H. Brachyhypopomus was erected to accommodate B. Subsequent to Mago-Lecciaseven additional species of Brachyhypopomus have been described, bringing the total to Two of these, B.
Two genera, Hypopygus Hoedeman, Arrozaal, and Steatogenys Boulenger,were until recently placed in the Hypopomidae, but were relocated to the family Rhamphichthyidae Regan by Live chat sex Arrozal De Sao Sebastiao et al. The Hypopomidae and the Rhamphichthyidae together constitute the superfamily Rhamphichthyoidea. The general biology of Brachyhypopomus is well known in comparison to other gymnotiforms, as reviewed below see 'Functional biology and ecology', in the generic descriptionand one species, B.
Here we provide a taxonomic revision of Brachyhypopomus. We confirm the validity of all 13 previously-described species, describe 15 new species Table 1and provide descriptions of morphology, ecology, and geographical distributions based on a thorough examination of available museum material.

We limit the presentation of osteological characters herein to those necessary to diagnose species where characters from non-invasive analyses were insufficient. Species accounts. The synonymy sections herein provide an opportunity to correct many Fat single women these errors. Nonetheless, we adopt a conservative approach by confirming or correcting the identity of species mentioned in non-taxonomic papers only where photographs or other illustrations, or exclusive geographical distributions permit unequivocal identification.

Elevation data refers to altitude above mean sea level. Morphometric measurements.
Body size measurements reported in this paper refer to total length TL - Sebawtiao distance from the tip of the snout to the end of the caudal filament, unless specified as length to end of anal fin LEA - the distance from the tip of the snout to the base of the last anal fin. Morphometric measurements are summarized in the schematic diagram in Fig. Due to non-linear Sebasyiao allometry we analyzed morphometric Sebsstiao only from specimens of reproductive size above the minimum size at which gonadal development occurs for each species Live chat sex Arrozal De Sao Sebastiao et al.
Measurements reported as a percentage of TL are given only for specimens with no Live chat sex Arrozal De Sao Sebastiao or regeneration.
Measurements reported as a percentage of LEA are given only for specimens with no damage or regeneration anterior to the anal-fin terminus. The following morphometrics represent the horizontal Looking to grow in a new life parallel to the long axis of the specimen, with the specimen extended on a flat surface - measured either with a ruler to the nearest 1 mm or, for smaller specimens, a Arroaal caliper to the nearest 0.

Anal-fin length AF - the distance between the bases of the first and last rays of the anal fin. See text for details.
Body, dhat view: Body, dorsal view: Head, lateral view: Head, dorsal view: Head, ventral view: Schematics based on B. All other morphometrics, listed below, were measured using the ocular micrometer of a Meiji Techno RZ stereomicroscope, to the nearest 0. We chose ocular micrometer measurements instead of point-to-point caliper measurements because the latter lacked sufficient precision and replicability for characterizing morphometrics in specimens smaller than ca.

We were unable to obtain ocular micrometer measurements from the holotype specimens of some previously-described species all previous descriptions employ caliper-based measurements.
In these cases we excluded the holotype from the tabulated morphometric ranges we present in the species redescription; this is clarified in the appropriate table legends.Naughty Wives Want Real Sex Concord New Hampshire
