Abstract.(cid:8212)Spilindolla, a new genus of Neotropical Coccinellini, is proposed to accom-
modate the species Cycloneda vigintiduonotata (Mulsant), C. darestei (Mulsant) and
Egleis constellata Mulsant. These three species constitute new combinations within Spi-
lindolla. The new genus is most closely allied to Spiloneda Casey and belongs to a
subgroup of nine other genera within the neotropical coccinelline fauna informally des-
ignated as (cid:8220)(cid:8216)Olla and allies.(cid:8221) Spilindolla is compared to related as well as superficially
similar genera. The species are described, keyed and illustrated and their distributions
given.
