Family: Gastrodontidae
Common name: Furrowed Glyph
Discovery: Hubricht, 1966
Identification
Width: 5.7 mm
Height: 2.6 mm
Whorls: 4.5
Glyphyalinia luticola is moderate to large-sized glyph with a low, slightly rounded spire. The very small umbilicus is nearly filled by the inside edge of the shell aperture leaving only a small fissure. The whorls increase moderately quickly in size, their basal surface is slightly rounded. The shiny and translucent shell is sculptured with widely and regularly spaced narrow indentations that run parallel to the nearly invisible growth lines. Shell color is a coppery brown and the animal slate grey. Internally, the epiphallus enters sub-apically, nearly at the center of the penis.
Ecology
This species is usually found in floodplain and swamp forests under leaf litter or on bare mud as well as in anthropogenic habitats (Hubricht, 1985). Most sites where Glyphyalinia luticola occurs have high to moderately acidic soil pH and the species appears to be an acidophile (Nekola, 2010).

Distribution
