Material examined. 1 female, Pernambuco, Brazil: Meu Rei cave , 08°29’14.1”S, 37° 16’48.8”W, 777 m a.s.l., 19- I-2016, Catimbau National Park, E. Barbier leg. ( LECA; Ps-012) .

Diagnosis. According to the description made by Beier (1974), the specimens of Ceriochernes foliaceosetosus Beier, 1974 can be easily distinguished by the carapace reddish-brown, slightly longer than wide, without eyes and eyespots, strongly granulated, the granules of the metazone covered with an epicuticle, reticulate in the form of a rough honeycomb, both transverse furrow narrow and not very deep, but distinct, the anterior curved laterally, the posterior closer to the rear margin, with six setae on the anterior margin, and eight on the posterior margin. All tergites divided, setae clavate and broadly foliated, rounded at the tip, curved and almost sessile, partially covered by epicuticle, with midrib, pleural membrane very densely granulated. Chaetotaxy tergal: 6: 8: 8: 6: 6: 8: 8: 8: 8: 8: 8: 2. Genital region operculum with a set of 12 setae, and ten setae on posterior margin. Chelicerae with six to seven setae on hand, es very short, three blades on the rallum, Serrula with 17 blades, galea with 5 very short branches distally. Pedipalps strongly reticulated, trochanter 1.0×, femur 2.58×, patella 2.15×, fingers not as long as the hand without pedicel, each with about 35–40 marginal teeth, the accessory teeth small and inconspicuous, present on the medial side only on the distal part of the finger, trichobothrium ist midway between isb and it, est proximal of ist; trichobothrium st closest to t.
