New species and records of crane flies (Diptera, Tipuloidea) from Great Smoky Mountains National Park, Tennessee and North Carolina, U.S.A.

A survey of crane flies (Diptera: Tipuloidea) was conducted at I I reference sites through sampling associated with the All Taxa Biodiversity Inventory (ATBI) in Great Smoky Mountains National Park in Tennessee and North Carolina, U.S.A. Two new species of crane flies, Ormosia (Oreophila)parviala new species and Tipula (Lunatipula) atreia new species, are described here. Ormosia parviala is most easily distinguished by the reduced wings of the female. Tipula atreia is a small Lunatipula, distinguished primarily by a trilobed ninth tergite, a minute outer gonostylus, and the appendage of the ninth sternite with straight pale setae. Significant range extensions are reported and discussed for ten species of crane flies: Antocha (Antocha) obtusa Alexander, Ctenophora apicata Osten Sacken, Discobola nigroclavata (Alexander), Hexatoma (Eriocera) spinosa Osten Sacken, Limnophila (Idiolimnophila) emmelina Alexander, Limonia maculicosta (Coquillett), Tipula (Lunatipula)flavibasis Alexander, Tipula (Lindnerina) illinoiensis (Alexander), Tipula (Lunatipula) monticola Alexander, and Tricyphona (Pentacyphona) autumnalis (Alexander).
