Abstract |
: |
Eight specimens of a new Acoelan Turbellaria, Goharia obscura
novo gen, novo sp. which belongs to a new family "GOHARIDAE", were
collected from a depth of about 50 cm inthe sandy lagoon at Ghardaqa and
north leddah in the Red Sea in 1986. The worm is dark brown with fine
white longitudinal strands. Symbiotic algae and eyes are totally missing. It
has a zeppelin shape. Reconstructions of the new Acoelan Turbellaria were
drawn from the medi~n sagittal position, by the examination of transverse,
longitudinal and frontal sections of the worm stained by Mallory stain which
gave excellent results.. Camera lucida was also used.
This worm is related to a new family GOHARIDAEbe causei t hasa peculiar
sense organ, situated near the anterior end, with a ventral aperture. The
mouth is ventral and the pharynx is missing. The female genital aperture
and the Antrum femininum are absent. The male genital aperture is located
dorsally very near to the postel:i°r end.
It is belonging to a new genus, due to the fact that it has from 4 to x
cuticularized bursa mouth pieces. The number of the sperm balls are variable.
The penis is cuticularized. The main retractor muscles of the sense
organ pass through the brain mass, and ends before the statocyst. It is a new
species,a s it possessesa highly developed nervous system, consisting of a
spherical submuscular nerve plexus, having 5 nerve stems and medio-dorsoventral
nerve commissure.
Bursa-seminalis is well developed, giving rise to 6 cuticularized bursamouth
pieces. The penis has a cuticularized tube, opening into the antrum
musculinum. |
