Evenhuis, Neal L., 2005, A review of the genera comprising species of the genus Eurynogaster sensu Hardy & Kohn, 1964 in Hawai‘i (Diptera: Dolichopodidae), Zootaxa 1017, pp. 39-60 : 56-57

Genus Uropachys Parent

( Figs. 11, 20, 28)

Pachyurus Parent, 1934: 305 . Type species: Pachyurus hawaiensis Parent, 1934 , by monotypy. [Preoccupied by Pachyurus Agassiz, 1831 .]

Uropachys Parent, 1935: 80 (new replacement name for Pachyurus Parent, 1934 ). Pachyurus hawaiensis Parent, 1934 , automatic.

Uropacys: Tenorio, 1969: 40 (misspelling).

Diagnosis: Species in this genus are distinguished from other genera by the following: absence of anterior preapical setae on all femora; hypopygium extremely large, larger than 1/2 length of abdomen; and cerci variably shaped, long (usually over 3 x width), sclerotized, possessing strong, modified bristles, especially at apex ( Fig. 28). As in Sigmatineurum , what appears to be a long thin upper surstylar lobe is actually the apicoventral epandrial lobe.

Hypopygium ( Fig. 28): Extending forward well past 4th segment, in some species up to 2nd abdominal segment. In lateral view: cercus elongate, sclerotized, rounded basally with fine hairs, becoming thinner medially, then enlarging to apex, medial and apical portions shining, with strong setation and/or modified setae, especially apically; surstylus unilobed, with short hairs apically; basiventral epandrial lobe relatively small, truncate apically, not elongate, without strong setae; apicoventral lobe inserted basoventrad of surstylus, long, thin, with apical setation; hypandrium length about 3 x width, with small recurved hook­like apex, with small rounded lateral lobe; postgonite well developed, rounded.

Discussion: After being transferred to Eurynogaster , Uropachys hawaiensis (Parent) , was given the new replacement name E. parenti by Hardy & Kohn (1964) because it was at that time preoccupied by Eurynogaster hawaiiensis (Grimshaw) . Now that it is removed in the present study from its secondary homonymy, Article 59.4 of the I.C.Z.N. Code (I.C.Z.N. 1999) requires that the original species [ Uropachys hawaiensis (Parent) ] be considered the valid name for the species, and Eurynogaster parenti Hardy & Kohn becomes a new synonym.

All species in this genus are restricted to the island of Kaua‘i.
