Gyliotrachela troglodytes van Benthem Jutting, 1950
“Gyliotrachela troglodytes is a very small species, perhaps most nearly related to the somewhat larger G. modesta. In the latter species, however, the last part of the ultimate whorl is free and the aperture is directed downward.” (Benthem-Jutting, 1949)
Benthem-Jutting (1949) original descriptions on Gyliotrachela troglodytes – “Shell small, with a moderately small, conical spire and a wide aperture which is not free, but adnate to the previous whorl. Reddish-brown. First 1 ½ whorls smooth, polished; the growth lines. There is no spiral striation. Not transparent. Whorls 4, the last one ascending towards the aperture. Sides of whorls rounded, only the last one is provided with an obtuse keel. There is a similar keel round the open, but not wide, umbilicus. Suture rather deep. Aperture widened, somewhat obliquely facing the sky. Quadrangular with rounded angles. Parietal and angular lamellae separated. Columellar, upper and lower palatal teeth large, infraparietal lamella small. Peristome continuous, somewhat thickened and expanded.”
Gyliotrachela troglodytes – “Dimensions: Height – 1.7-2.0 mm; Breadth – 2.1-2.5 mm; Height of aperture – 1.0-1.2 mm. (Benthem-Jutting, 1949)
