Diagnosis
Sciadonus pedicellaris is long, slender and compressed with protruding lower jaw and differs from all other Sciadonus species by the following combination of characters: no black pigmentation on body, dorsal fin rays 90-107, precaudal vertebrae 43-49, origin of anal fin below dorsal fin rays nos. 44-56 and below vertebrae nos. 44-49. Tissue flaps anteriorly on lower jaw well developed on most specimens.
Description
The principal meristic and morphometric characters are shown in table I. Body slender and compressed with scaleless, loose skin. Skin and peritoneum transparent showing the inner organs. Mouth horizontal with protruding lower jaw. Most specimens with a pair of distinct tissue flaps anteriorly on lower jaw (cf. Fig. 7 View Figure 7 ). Small deep-set black eyes placed above posterior third of upper jaw. Opercular spine absent. Sagittal otolith ( Fig. 10 View Figure 10 ) small, half as thick as long; sulcus undivided reaching to about middle of inner face and with wide opening at anterior rim. Origin of dorsal fin at about tip of pectoral fin; anal fin origin well behind midpoint of fish. Vertical fins joined. Pectoral peduncle about three times as long as high. Pelvic fin rays very thin and short, when present; lacking in about half of the specimens. Anterior gill arch ( Fig. 11 View Figure 11 ) with 12-15 small, knob-formed rakers each provided with 2-6 short spines and with gill filaments equal in size to rakers. Filaments on second and third gill arch twice the length of those on anterior arch. Pseudobranchial filaments not observed. Females with a pair of well-developed claspers ( Fig. 12 View Figure 12 ). Penis partly covered ventrally by the urogenital hood that ends in two small wing-like prolongations on each side of penis and a pair of probably vestigial claspers placed at each side at base of hood ( Fig. 13 View Figure 13 ). A thorough description of the holotype and paratype of the now synonymized Leucochlamys galatheae is given in Nielsen (1969: 75-78).
