Copelatus cessaima sp. nov. is described from Brazil. The new species was collected in water puddles inside of caves found in an ironstone formation and has typical troglomorphic characters: the eyes and metathoracic wings are absent, the elytra are fused and the body has long setae. This is the second species of Copelatinae reported as troglomorphic and the first record of a troglomorphic Dyti...

A profile of Guanajibo clay (Plinthic Kandiudults) was evaluated to determine the ironstone content in horizons and its chemical, physical mineralogical properties. The mineralogy characterized by X-ray diffraction (XRD) iron aluminum oxide determined selective dissolution, using citrate-bicarbonate dithionite (CBD) ammonium oxalate (OX) extractions. Soil color ground were with Munsell charts. ...
