wesenbergensis brevis (Eisenack), however, the latter has a distinctively subconical
chamber and has so far been encountered only in considerably younger strata.
Prosternal process massive, subconical
, with a bluntly round tip.
Antenna: 10, 5, 9, 14, 98; scape and pedicel slightly flattened laterally, brownish yellow, darker dorsally; scape subconical
, pedicel shorter than scape and cylindrical, and with apical crown of setae, the dorsalmost longer; postpedicel subtriangular, brown, shortly pilose; stylus long, 2nd stylomere 7 x as long as 1st stylomere.
Individuals captured (CORBIDI 010299-010301) exhibit diagnostic characteristics mentioned by Duellman and Hedges (2008) such as: tympanic membrane not differenced and tympanic annulus absent, upper eyelid bearing small tubercles, vocal slits and nuptial pads absent, subconical
tubercle on the heel and outer edge of tarsus with row of subconical
tubercles and a green dorsal coloration.
Structure: Scutellar disk with high subconical
tubercle directed upward.
Third to fifth pereopods moderately stout, notably decreasing in length from third to fifth; dactyli subconical
Legs subcylindrical; metatrochanter bearing 11-12 cuticular folds medially; metatibiae unarmed laterally, bearing apical row of three black-tipped spines and a short, moveable subconical
spike-like spur; slightly longer than the longest apical spine, without marginal teeth.
Internal face with 4-5 subconical
granules arranged in a longitudinal row.
3); venter areolate but also bearing larger warts admixed with smaller granules; pair of subconical
subanal warts; no anal sheath; upper surfaces of limbs smoother than dorsum; series of 4 low ulnar tubercles; palmar tubercle bifid, much larger than oval thenar tubercle; supernumerary palmar tubercles present; subarticular tubercles round, nonconical; fingers bearing lateral fringes; disks of outer fingers about twice as wide as digit below disk, round apically; disks of inner fingers smaller, round; all disks bear ventral pad, completely defined by circumferential grooves; first finger shorter than second; no nuptial pad in males.
The specimens of fangjaw eel were identified using the following combination of diagnostic characteristics (Castro-Aguirre and Suarez de los Cobos 1983; Allen and Robertson 1994): body elongated, cylindrical, pointed at both ends; tail longer than head and trunk; pectoral fins present; gill opening relatively elongate, vertical and lateral; snout short, subconical
, slightly constricted near tip; teeth very strong and pointed, biserial, largest anteriorly on jaws; body overall tan with abundant small, brown spots on back and sides; and dorsal fin brown.
Adpressed leg places heel at posterior margin of eye; tibia length about one half that of snoutvent; inner metatarsal tubercle elliptical, about equal in area to disc of first toe; outer metatarsal tubercle inconspicuous, smaller than the rounded to subconical
subarticular tubercles of toes; toe discs elliptical to nearly circular, slightly smaller than discs on outer three fingers; a basal web between first and second toes, extending as a fringe along inner margin of second toe; webbing between other toes variable from near distal end of antepenultimate phalanx of digit four to distal end of penultimate phalanx of digit five.
The preoccipital glabella is subconical
in outline, rounded anteriorly, 68-72% of the cephalic length (glabellar spine excluded), and 30-35% of the cephalic width posteriorly.
