Kaliella gregaria (Tillier & Bouchet, 1988)
Tiller & Bouchet (1988) original descriptions on Gunongia gregaria – “Shell thin, soft, fragile, biconical, consisting of a little less than one protoconch whorl and three teleoconch whorls with rapidly increasing diameter. Protoconch with a distinct (except in the nuclear region) sculpture of small incremental ribs and much fainter incised spiral groves. Protoconch/teleoconch transition distinct. Teleoconch whorls convex, with appressed suture; body whorl large, occupying 83% of total shell height, with a strong peripherial keel. The axial sculpture consists of very regular and fine incremental lines, and more widely and more irregularly spaced, stronger axial ribs. The incremental lines, but not the axial ribs, extend on the base of the shell below the peripherial keel. The spiral sculpture consists of very regular, fine spiral groves, forming with the incremental lines a delicate reticulation which is best seen through the transparent shell. Aperture somewhat ovate, with upper and lower parts of the outer lip forming a sharp angle at the level of the keel. A very thin glaze appressed on the body whorl marks the inner lip. No umbilicus. Colour of the shell with periostracum amber-brown.”
“The radula has ca. 300 latero-marginal teeth per half-row; they are distinctly smaller than in dendrobates.” (Tiller & Bouchet, 1988)
“The foot is aulacopod, and uniformly dark in colour in living animals. The pallial border extends into one nuchal and two lateral short lobes. The sigmurethrous pallial complex occupies the last 0.25 whorls. The kidney is wider than in other species described here, sigmoid in shape and occupies nearly one half of lung length; obviously these characters are related to lung shortening. The stomach is ca. 0.6 whorls long, but the intestinal loops occupy less than 0.2 whorls between top of lung and stomachal crop, in relation to visceral hunp shortening.” (Tiller & Bouchet, 1988)
“The cerebral commissure an the connectives are all short in length. The visceral chain is distinctly displaced on the right side: the left parietal ganglion is located approximately in the median plane separating the pedal ganglia, and the left pleuro-parietal connective is shorter than the perieto-visceral. The visceral and right parietal ganglia appear to be almost fused together.” (Tiller & Bouchet, 1988)
“Genital apparatus: in all specimens collected, the epiphallus is about twice as short as the penis proper and is a simple tube which opens into the penis through a prominent papilla. The penis exhibits two lateral outgrowths: one on the vaginal side is horn-like and about equal in size to the epiphallus; the second one, which is opposite the former, looks either like a very short lateral horn, or like a very strong appendage which is reminiscent of the penial appendage found in some Orthurethra, or of a spermathecea. In both cases, the transverse penial apical ridge enters both appendages. Despite the morphorlogical amplitude of the discontinuous variation in size of the second penial appendage, we cannot find any other character which could indicate that the two forms are not conspecific. From its morphology this appendagem when developed, is not involved mechanically in copulation and we have no idea of what its function can be, if it has any. It differs from the spermathecea of the Microcystinae by both its position opposite to the oviduct and its morphology; consequently it is probably not homologous with this structure.” (Tiller & Bouchet, 1988)
Gunongia gregaria – “Dimensions of the holotype: height 5.2 mm, diameter 6.8 mm; aperture height 3.4 mm, breadth 4.0 mm.” (Tiller & Bouchet, 1988)
Type locality – “upper montane zone of Mt. Kinabalu (Sabah, Borneo)” (Tiller & Bouchet, 1988)
