ETYMOLOGY. — This new species is named after Liu Zheng-Ping, who has made important contributions to the discovery of this new species.
TYPE LOCALITY. — China, Sichuan, Chengdu Shi, Dujiangyan Shi, Qingcheng Houshan, 1200 m a.s.l.
DIAGNOSIS. — A Coccoglypta species with a rounded body whorl, greenish to yellowish colour and weak sculpture on the ventral shell surface.
DESCRIPTION
Shell dextral, rather large, light brown (dorsal surface) to greenish or yellowish (ventral surface, and dorsal side behind the aperture); colour changing below keel, and some light colouration indicating some growth lines; shell depressed globular, body whorl rounded or with very slightly marked keel (if present, mostly visible from ventral view of the body whorl); entire shell consisting of 5.25-5.75 whorls, separated by rather shallow suture, sometimes indicated by a whitish line; protoconch consisting of 1.5-1.75 whorls, matt, rather smooth, dorsal side of teleoconch dominated by irregular, rather rough wrinkles and tubercles (tubercles appearing after the first 1.5 whorls of teleoconch); some fine spiral grooves also visible; ventral surface without or with much less prominent tubercles, rather “hammered”, irregularly wrinkled and spirally grooved; aperture strongly oblique to shell axis, white; peristome expanded (mostly in basal and umbilical direction) but not reflected; parietal callus weak, only indicated by fine whitish calcareous layer, which is transparent in fresh shells; umbilicus open, moderately wide, showing all whorls.
Measurements
D = 29.1-32.9 mm, H = 16.1-20.6 mm (n = 3). Remarks on the genitalia
From a single specimen anatomically examined from Qingcheng Houshan (Figs 3-4). Right ommatophoral retractor crossed vagina and penis. Inner wall of the penis finely reticulated (Fig. 4A), produced by the perpendicular projections of the slender longitudinal folds. Inner wall of vagina with widelyspaced, sometimes converging longitudinal folds (Fig. 4B).
DIFFERENTIAL DIAGNOSIS. — Coccoglypta liui Páll-Gergely, n. sp. differs from C. pinchoniana, which also occurs sympatrically, by the usually narrower umbilicus, weaker sculpture of the ventral surface, the lighter colour, and the less keeled body whorl. The ventral side of C. pinchoniana is dominated by ribs and tubercles, but also has fine spiral grooves. However, the ventral shell surface of Coccoglypta liui Páll-Gergely, n. sp. has much less prominent tubercles and is dominated by spiral grooves.
DISTRIBUTION. — So far this species is known only from Qingcheng Houshan and Qingcheng Shan in Sichuan Province, China (Fig. 5).
REMARKS
Our observations on the genitalia generally match with those of Schileyko (2004), based on a C. pinchoniana specimen collected in Emei Shan. The notable differences are the following: 1) the mucus glands form a single oval mass, not separated clearly as on Schileyko’s (2004) drawing; 2) we have not found a twisted part of the spermathecal stalk in a capsule; and 3) the bursa copulatrix is smaller and more elongated than the specimen examined by Schileyko (2004). It is yet unclear which of these differences represents speciesspecific traits.
