Four or more rows of sessile macrotubercles are present; papillae are usually present on the ventrum and sometimes between the rows of macrotubercles on the dorsum. Microtubercles are absent. Five or seven antennae are present on the anterior end and the peristomial cirri are usually well developed. All setae are composite; recurved hooks are absent. Eyes may be present. Genotype is Sphaerodoropsis sphaerulifer (Moore, 1909, p. 336) from California.
