115.3 c;nellopogon mgneans: 22.5 cm
116: EXOCOETIDAE (FL YINGFISHES)
Body dark iridescent blue dorsally, silvery white ventrally; P black with pale margin, the central portion crossed by a
yellowish stripe becoming narrower toward anterior fin
margin; V usually with a prominent black spot. In juveniles,
body with dark bars (up to 6 in smallest specimens). Attains
24 cm SL. Tropical eastern Atlantic (to 17°S) and IndoWest Pacific; possibly a complex of related taxa. One specimen, a juvenile (SAM 23328), known from our area.
116.4 Cheilopogon pinnatibarbatus altipennis
(Valenciennes, 1846)
PLATE 16
Small head flyingfish
Kleinkop-vlieende vis
Exocoetus altipennis ValencienRes, in Cuv. & Val., 1846: 109 (Cape of
Good Hope; syntype MNHN A.9920 is here designated as the lectotype).
Exocoetus longipinnis Castelnau, 1861: 64 (Agulhas Bank). Cypselurus
bahiensis (non Ranzani): Smith, SFSA No. 212* (in part). Cypselurus pinnatibarbatus: Gibbs & Staiger, 1970: 457* (in part).
D 12-14; A 9-12; P i, 13-15; predorsal scales 39-45; vertebrae 49-51; total
GR 20-2S. Depth 5.7-7.S, P 1.3-1.5 in SL. Palatine teeth usually present.
A origin below 4th to 6th D rays; V reach last A ray, their origin nearer
head than to C. Juveniles elongate, with high D like that of Parexocoetus.
Body dark iridescent blue dorsally, silvery white ventrally; D with or without black spot; P dark brownish grey (with
narrow, pale, transverse stripe in fishes 20-30 cm SL). Attains 38 cm SL. A neritic species occurring from the Cape to
Kosi Bay, also on Agulhas Bank; other subspecies in most
subtropical areas.
Genus Cypse!urus Swainson, 1838
About 12 species (17-24 cm SL); Fowler (1934) recorded
Cy. nigripennis (Val.) from Natal (Smith, SFSA No. 213),
but the figure of the juvenile with 3 unbranched P rays appears to be Prognichthys brevipinnis. Although no species
of Cypselurus (in the restricted sense used here) is definitely
known from southern Africa, there are 4 Indo-West Pacific
species in the northwestern Indian Ocean that may be found
in our area. These 4 species can be distinguished by the following Key.
