Diagnosis Test lenticular, proloculus followed by planispirally enrolled and involute tubular second chamber or coiling axis may vary slightly, chamber floor convex; wall with well-developed thin dark finely granular inner layer showing lateral thickening or contreforts, hyaline radial layer covering the umbilical region and thinning markedly toward the test periphery; aperture at the end of the tubular chamber, semilunate because of the convex chamber floor. L. Carboniferous (Visean); USSR: S. Urals; Belgium; Iran. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
