«The holotype, a left valve, is moderately convex and higher than long. The surface is ornamented with about twelve, radial, rather angular ribs, separated by wide, shallow furrows. There is an additional, very fine, divaricate ornament, forming in part, by intersection, an interlaced pattern, particularly well developed on the antero-central part of the body of the shell; this ornament becomes indistinct in the umbonal region. The ears have only a very fine concentric ornament.
The ornament in shells like Pecten (Indopecten) clignetti Boehm, has a zigzag, not an interlaced-divaricate, pattern. Name. Chiwan, an Indian proper name. Type. The holotype, cat. no. 8786, is from the Mahaffy Cliffs fauna on Mahaffy cliffs.» FRANK HARRIS MCLEARN, 1941

«Stratigraphic range.— Middle Triassic (Ladinian)–Upper Triassic (Carnian) (Waller in Waller & Stanley, 2005). Waller (in Waller & Stanley, 2005) included the type species within Loxochlamys, from the upper Ladinian, and two other species: Pecten chiwanae McLearn, 1941, and Pecten sasuchan McLearn, 1941, both from Carnian beds.»
