Asca quinquesetosa .— Hurlbutt, 1963: 513; Wood, 1966: 48.

Material examined. Six females – Cuba, coll. from soil and litter.

Remarks. Asca quinquesetosa was described from the nest of a booby on Clipperton Island ( Wharton, 1941), and has been recorded from litter and moss in Hawaii ( Hurlbutt, 1963) and New Zealand ( Wood, 1966). It is now recorded from Cuba for the first time, from soil and litter. Our specimens agree very well with the description given by Hurlbutt (1963). There are two setae and two circular structures on each postero-dorsal tubercle ( Figure 7 ), the epistome has two strong lateral points, and the margin between the points is slightly convex ( Figure 6 ), all dorsal setae are minutely barbed and distance J4–J4 is less than J4–Z3 ( Figures 1, 4, 5 ).
