Gyliotrachela salpinx van Benthem Jutting, 1961
“Gyliotrachela salpinx differs from G. hungerfordiana (Mlldff) in having a much lower spire, a shorter trumpet, and more teeth in the aperture. From G. depressispira v. B. Jutting the new species differs in having a narrower umbilicus, and a somewhat higher spire. In addition the aperture is directed obliquely sidewards and upwards, wheres in G. depressispira the aperture points to the sky. Compared with G. transitans (Mlldff) and subspecies Gyliotrachela salpinx has a lower spire, a wider umbilicus and more teeth in the aperture. From G. modesta v. B. Jutting and G. emergens v. B. Jutting the new species differs in having a lower spire, a wider umbilicus, a more conspicuously keeled periphery, and in possessing more teeth in the aperture. G. salpinx differs from G. troglodytes v. B. Jutting in having a slightly lower spire, a wider umbilicus, a more conspicuously keeled periphery and a longer trumpet. In addition the number of teeth in the aperture is larger in G. salpinx. The nearest relative is G. luctans v. B. Jutting. From this species G. salpinx differs in being smaller, with a shorter trumpet. The colour of the new species is more yellowish-brown, instead of reddish-brown, as in G. luctans. The number of teeth is about the same in both species.” (Benthem-Jutting, 1961)
Benthem-Jutting (1961) original descriptions on Gyliotrachela salpinx – “Shell consisting of a low-conical spire and a broad last whorl, ending in a free, trumpet-shaped part. Yellowish-brown. First 1 ½ whorls mamillate, smooth, polished. The others are irregularly striated by oblique growth lines. This striation is crossed by still finer spiral lines, especially visible on the last whorl below the periphery. Not transparent. Whorls about 4, the first 3 ½ regularly coiled, the last half whorl widening towards the aperture and in the distal part disconnected from the rest of the shell forming a small, oblique, ascending trumpet. Two first whorls well-rounded, forming a mamillar apex. Third and fourth whorls more flattened. Just above and below the periphery the last whorl is pinched so as to give the shell an angulate appearance. The angulation continues on the free part, up to the aperture. Opposite this keel, and on the dorsal and ventral sides the trumpet bears three other keels, rendering the free part almost quadrangular in diameter. Umbilicus open, wide, showing the previous whorls. Aperture little oblique, Peristome continuous, thickened, expanded. Angular and parietal lamellae separate, the angular thin, nearly reaching the peristome edge, the parietal thicker, deeper down in the throat. On the parietal side there is further one (or two) weak infraparietal tooth. The columellar side bears a weak supracolumellar, a strong columellar and a weak infracolumellar tooth. Along the palatal side there occur 1 upper palatal, 2 interpalatal, 1 lower palatal and 2 infrapalatal teeth.”
Gyliotrachela salpinx – “Dimensions: Height – 1.6-1.9 mm; Breadth – 2.4-2.7 mm; Height of aperture – 1.0-1.2 mm. (Benthem-Jutting, 1961)
