THE NAGATAI SPECIES GROUP

DIAGNOSIS: Vein C with row of small, dark spinules between apices of R 2+3 and R 4+5. Male genitalia: Reduced and basic; subepandrial sclerite well developed but not extended past posterior margin of epandrium; outer paraphyses small, simple (no spines); inner paraphysis present, but small, simple.

NEARCTIC SPECIES: Amiota raripennis , sp. nov.

COMMENTS: Chen and Toda (2001) erected this species group to accommodate three OldWorld species. This group may also include A. steganoptera Malloch , known from Costa Rica, plus several undescribed Neotropical species, all of which possess costal spinules. These species will be treated in a future study. Amiota raripennis differs from the Old World species by several apomorphic features of the epandrium: setae very sparse, very short; with pair of distinct, setulose ventral epandrial lobes. Plesiomorphically this species differs from the Old World species by lacking the lobe on the hind trochanter in the male. He et al. (2009) provided a treatment of the Old World species. Thus, there appears to be two lineages, an Old and New World one.
