Genus Nephrotoma Meigen
Pachyrrhina Macquart, 1834, Hist Nat Ins., Dipt 1:88 (variant
spellings, Pa~hphi~~ Pachyrhyna).
Nephrofoma is one of the largest genera in the
Tipuline crane flies, being best developed in the Holarctic,
Oriental, and Ethiopian regions, with about 40
species recorded from the Nearctic region and in the
1965 Catalog of the Diptera. Of these, it appears that
a single species occurs in California, the prior name
being wulpiana (Bergroth). This was described from
a single female specimen taken in Siskiyou County
by Behrens and has not been recognized in recent
collections. The later described occidentalis (Doane)
is abundant in the state and while differing in minor
details of coloration from Bergroth?s description of
wulpiana, appears certainly to represent the same
species and therefore is placed in the synonymy. In
case future investigations should indicate that two
distinct species are involved, all records here listed
should be referred to occidentalis with the single
exception of Bergroth?s type specimen of wulpiana
(Siskiyou county, below). A second very distinct
species, Nephrotorna alfissima (Osten Sacken), is
western, having been taken in Nevada. It is almost
entirely black or, in the color form, eryfhrophrys
(Williston) with the abdomen chiefly orange, the
hypopygium black.
