Minibiotus gumersindoi Guil & Guidetti 2005 Large, round pores in transverse rows and larger round-shaped cuticular pores over the double-claws differentiated this species from any other Minibiotus species. Three round-shaped macroplacoids and microplacoid were within the pharyngeal bulb. Double-claws were of hufelandi type. Small and smooth lunules on all double-claws. Two animals had ocular spots, four lacked these structures, and in two it was not possible to determine their presence or absence. Body size range, among eight specimens found in LF and MR samples, was 153 to 212 μm; mean 155 μm (SD 37). Minibiotus gumersindoi was found at four sampling points (Table 3).
