Colour red. Eyed. Cuticular sculpture composed of many small round or polygonal projections (see Figure 1a). The biggest granule with a diameter of 1.8 mm. Ventral side smooth except the area beside the gonopore with many small pores. Cephalic appendages include internal buccal cirrus, cephalic papilla, external buccal cirrus, cirrus A, and clava; lateral and dorsal appendages consist of filaments D, C dand spine D d. Armour consists of single cephalic plate, scapular plate, first single median plate, first paired-plates, second median plate, second paired-plates, and terminal plate; third median plate absent, terminal plate with normal notches; two paired-plates with smooth bands. The fourth pair of legs with dentate collar containing six or seven teeth. Papilla-like projection present on the lateral surface of the fourth pair of legs, teeth present on the first pair of legs. Lateral side of each leg with many small granules (see Figures 1a, b, 2a). Spurs that pointed towards the base of the claw present on the internal two claws on all legs; three short teeth present on the external claws near the base on hind legs, a small tooth also present on the external claws near the base on third pair of legs (see Figure 2b, c).  Figure 1.  Echiniscus marleyi sp. n.(a) Habitus in dorsal view (holotype) focused to show the sculpture and plates; (b) habitus (holotype) focused to show claws. Scale bars: 50 mm. Eggs smooth, 98.9 mmlong, 83.2 mmwide. Laid in exuviae.  Etymology This species is dedicated to Mr Nigel Marley, School of Biological Sciences, University of Plymouth, UK.  Figure 2.  Echiniscus marleyi sp. n.(a) Habitus (holotype); (b) claws on first pair of legs; (c) claws on fourth pair of legs.
