With 12 circumpeduncular scales, it differs from P. longicaudatus, the undescribed species coded in Sullivan et al. (2002) as P. sp. ‘OFF’, P. batesii and P. tavernei which all have 16 or more. With its relatively sharp V-shaped head profile, P. sphekodes differs from P. batesii, P. gabonensis, P. retrodorsalis, P. tavernei and P. kingsleyae which have distinctly blunt or U-shaped snouts. P. sphekodes has type NPp electrocytes in its electric organ, as do seven other Paramormyrops from Lower Guinea, while P. batesii and P. kingsleyae have electric organs composed of electrocytes with penetrating stalks innervated on the anterior face (Type Pa). These characters are summarized in the key and in Fig. 16.</p> <p>Paramormyrops sphekodes differs from P. curvifrons in head and snout shape. Head and shout are shorter, deeper and more rounded when viewed laterally in P. sphekodes compared to P. curvifrons. P. curvifrons also has a downward sloping forehead, protruding snout and enlarged chin. The ratio of HL to SL is 23.5–26.9 in P. curvifrons, higher than 21.5–23.4 in P. sphekodes (Fig. 5A, Table 2), while the ratio of HD to HL (external measurement using callipers) is reduced in P. curvifrons compared to P. sphekodes (Fig. 5C). The ratio of pre-pectoral distance to pre-dorsal distance is greater in P. curvifrons compared to P. sphekodes (Fig. 5B, Table 2), and P. curvifrons has a significantly narrower snout than P. sphekodes measured by either snout angle (Fig. 5G) or ratio IOW/SNL (Fig. 5D, Table 2).</p> <p>Paramormyrops sphekodes is most easily confused with the species referred to above as SN4, but SN4 may be recognized by its much longer duration EOD, and by subtle morphometric characters discussed above and illustrated in Figs 3 and 4. Other distinguishing characters are presented below in the description of the new species.</p> <p>Description: Based on the lectotype Fig. 1A (above) and 1B and 10 other specimens, Table 2. Figure 7 shows five specimens in photographs of live fish in the field.</p> <p>A small-bodied Paramormyrops, the largest is a male, 133 mm SL, 153 mm TL. Body laterally compressed, maximum width at opercular bones. Viewed laterally, dorsal and ventral profile nearly parallel from behind the head to the first anal ray. Median BD 16.1% SL at pectoral fin, 17.6% SL at the urogenital pore. The ratio of these two BDs 84–89%, indicating that the depth changes little from anterior to posterior of the body anterior of the anal fin. Caudal peduncle length 17–20% SL, slightly wider at its origin than middle, depth 25–29% CPL. Lobes of caudal fin rounded.</p> <p>Lateral head profile above eye usually gently convex to very slightly concave in some individuals (Fig. 7, #1214). Snout short and smoothly rounded (Fig. 7). Forehead downward-sloping from halfway between opercular opening and snout tip. Tip of the snout one half eye diameter below the ventral margin of the eye. Viewed dorsally, head and snout V-shaped or sharp, median snout angle 53.6°, less sharp than P. curvifrons (Fig. 5D).</p> <p>Mouth small, rictus directly beneath nares. Chin protrudes slightly below gular region, not extending beyond snout. Eye small, ED 11–14% HL, positioned mid-laterally. Eye socket forms pale ring around pigmented eye, with gold iris and dark centre. IOW 26.8–29.3% HL. Anterior naris about 1/3 distance from snout tip to eye, slightly below line drawn through centre of eye, posterior naris halfway between anterior naris and eye, at about level of eye’s lower margin. Opercular opening begins anterior to base of pectoral fin. POL 60–68% HL.</p> <p>Pectoral-fin origin beneath posterior terminus of opercular opening, slightly below mid-horizontal line, length 12.4–17.0% SL, 11 rays. Pelvic-fin origin at 35.0– 38.8% SL, length 9.2–10.8% SL, positioned ventrally, 6 rays. Dorsal-fin origin at 64–65% SL; anterior margin gently convex, trailing margin concave in first third, remainder levels off at ½ DFH. Maximum height 62.3– 79.2% DFL, 20–23 total rays. Anal-fin origin slightly anterior to dorsal-fin origin: dorsal-fin origin above seventh (fifth branched) anal-fin ray. Anal fin mirrors general shape of dorsal fin, maximum height 45.2–65.0% AFL. In males, anterior AFR thickened and stiff with a noticeable notch at the base of the anal fin, spanning anterior half of anal-fin base. End of anal-fin base terminus directly beneath end of dorsal-fin base, rays 24–28. Lobes of caudal fin rounded, equal, slightly wider than caudal peduncle, deeply cleft, scaled at their bases.</p> <p>Scales fine, cycloid, absent from head. Pierced lateral line scales, 63–68 based on recent specimens (lectotype = 72, significantly fewer than Sauvage’s description of 85 which must have been total scales rather than pierced scales). Our counts of lateral line scales on the lectotype are unreliable because of damage to the specimen, other counts and measurements for the lectotype are indicated separately from other specimens in Table 2. Scales between lateral line and anterior base of dorsal fin 9–11, 10–15 scale rows between pelvic fin and lateral line. Circumpeduncular scales 12. Vertebrae: 43–45 total, 18–19 precaudal, 24–26 caudal. Teeth bicuspid, 5 in upper, 6 in lower jaw.</p> <p>Coloration: All fins with lightly pigmented rays, membranes hyaline. Dark band absent between dorsal and anal fins. Body darker dorsally, lighter ventrally. When alive, tan-brown body with yellow-olive or golden accents on top of head, back, and belly. Mouth, chin, and gular region unpigmented, whitish. Many small unpigmented spots and pores over electroreceptors (mormyromast and ampullary organs) visible on top of head and back, with fewer, large white spots (knollenorgans) on head. Preserved specimens uniform greyish-brown.</p> <p>Electric organ discharge: Short biphasic pulses – head positive first then head negative – average duration, 0.851 ± 0.352 ms (Fig. 8A, C, Table 3). First positive peak, P1, width W1 0.519 ± 0.194 ms (range: 0.320 –0.940 ms) – 1.6 times longer than width W2. First-time derivative of EOD rises smoothly from baseline with a single peak before P1 (Fig. 8B). Power spectrum of EOD peaks at 1910 ± 540 Hz (n = 9, Table 3, Fig. 10 D, E). Other quantitative measurements of EODs are summarized in Table 3 using reference landmarks illustrated for the biphasic EOD in Fig. 8A and its power spectrum in Fig. 8D.</p> <p>Several other species of Paramormyrops with biphasic EODs possess electric organs composed of electrocytes with N on- P enetrating stalks that are innervated on the p osterior faces of each cell (Type NPp Bennett, 1971; Bass, 1986; Sullivan et al., 2000; Gallant et al., 2011). Other species in this and other genera produce triphasic EODs (three peaks), beginning with a small head-negative phase P0, in advance of the larger head-positive phase P1, and the final head-negative phase P2. In all species with triphasic EODs, the electric organs are composed of electrocytes with P enetrating stalks innervated on the a nterior face of each cell (Type Pa in Alves-Gomes &amp; Hopkins 1997). Inspection of the EODs of all P. sphekodes reveals that the P0 peak is absent, even when the discharge trace is expanded 20 times by amplification (Fig. 8A, thin trace), suggesting that the electric organ is composed of Type NPp electrocytes. This is confirmed by dissection and histology shown in Fig. 9.</p> <p>Like many other mormyrids, P. sphekodes exhibits a sex difference in EOD waveform duration. One male recorded near the end of the rainy season in May 2011 had the longest EODs in all our EOD recordings (1.60 ms), but other, smaller males recorded early in the rainy season of September 2014 had EODs more similar to those of females. The averages of male and female EOD durations do not differ significantly (Student’s t = 1.439, d.f. = 7, P = 0.19, Table 3). In all adult males with SL&gt; 115 mm, we note that the ratio of the width of the second peak, W2, to total duration, DT, is greater than for that for females (Student’s t = 2.99, P = 0.03). The ratio of W1 to DT is correspondingly less for males. The variation seen for male EODs might be a reflection of seasonal changes in male pulses which begin to elongate before or shortly after the onset of the rains when most mormyrids breed (Hopkins, 1980, 1981; Hopkins &amp; Bass, 1981; Bass &amp; Hopkins, 1983, 1985).</p> <p>Distribution. In spite of several previous collecting trips to the lower, middle and upper Ogooué River of Gabon in 1999, 2001 and 2002, our only collections of this species are from Doumé, the type locality (2011, 2014), and the Sébé River, about 45 km from Doumé (2014). Both sites are within the Ogooué-Lolo Province of Gabon (Fig. 10) and both are large river habitats with rocky bottoms, sandy substrate, with rushing water and rapids (Fig. 11); this species was absent from nearby streams and other smaller tributaries.</p> <p>Etymology: The name sphekodes comes from the Greek, σφήκα, for wasp, which may refer to the fish’s elongate and slender body (Harder, 2000); however, Sauvage (1879, 1880) gives no explanation for his name for this species.</p> <p>The specimens referred to as ‘SN4’ above and in Sullivan et al. (2002, 2004) are here described as a new species.</p></div> 	http://treatment.plazi.org/id/F84B0818F2760736FF44B93D8AA4FCE7	Public Domain	No known copyright restrictions apply.
