Family Delphacidae Leach, 1815
Subfamily Asiracinae Motschulsky, 1863: 108.
Tribe Ugyopini Fennah, 1979
Genus Ugyops Guerin-Meneville, 1834: 477.
Type species (in original combination): Ugyops percheronii Guerin-Meneville, 1834.
Distribution
Widespread, but patchy in tropical regions. As noted in Fennah (1964: 119) concerning Ugyops
“Its members are impressively widespread among oceanic islands of the Pacific, are found in the Mascarene Islands, and range through tropical South America into the Greater Antilles. In the continental areas of the Old World… the genus is not represented in Africa and in continental Asia has been found only on the south-eastern seaboard, in “Cochin-China”. It is known that species of the genus occur in northern Australia, New Guinea, the Moluccas, Borneo and Sumatra and in some of the smaller islands of Indonesia, but the only evidence of its presence on the continent immediately north of Java and Sumatra is provided by specimens from Thailand in the present collection, and of its presence in the eastern part of the Indian Ocean by a specimen from Narcondam Island.”

Subgenera
Several subgenera have been defined (such as Paracona Fennah, 1965: 11), but they have been inconsistently used and few species are clearly and explicitly placed within subgenera. Fennah, 1964, divided Ugyops into two functional groups – long-winged forms that are Ugyops s.s. (noting U. kinbergi as an example in addition to the type species), and short-winged forms (the Livatis group), noting only U. annulipes. I will specify subgenera here once I have determined their species composition.
Paracona Fennah, 1965:11 (Type species Ugyops pelorus Fennah, 1965) includes Ugyops raouli.
Livatis Stal, 1859: 274 (Type species Delphax annulipes Stal. 1859) includes (at least) Ugyops annulipes, U. brevifrons and U. longifrons.
Ugyops Guerin-Meneville, 1834 – this subgenus contains all species not explicitly placed in the other subgenera.
Recognized species
There are 101 species and 12 subspecies currently placed in this genus (distribution information incomplete, I’m working on updating the Old World species; the “?” in the distributions are data I need to check with the original source).
(Fennah, 1971 indicates that the ICZN considers the –ops termination as masculine. ICZN 1999 article 30.1.4.3 (viz. ” A compound genus-group name ending in -ops is to be treated as masculine, regardless of its derivation or of its treatment by its author”) specifically indicates that ‘-ops‘ is male; below, where I have emended names to be masculine, I indicate this with a “*” to indicate that the emendation may not be published; I will remove this indication where I subsequently find the emended termination has been published).

Plant Associations
Reported plant associations are highly varied and those reported often need confirmation. Possibly, they are primitively associated with ferns or some other non-angiosperm. I have seen adults resting on tree-trunks in Central America, but have swept nymphs from understory forest vegetation (in Costa Rica, at least).

Economic Importance
Limited. Most species poorly known, not on economic plants.
Recognition
Among genera in the New World, Ugyops is very similar to Canyra, but not particularly close to any other genera. Both are large delphacids with both antennal segments long and round in cross-section. The only feature that might distinguish the genera (if any) is that Canyra bears a longitudinal sulcus on the dorsal side of the first antennal segment that Ugyops should lack. However, a casual, but incomplete, review of New World Ugyops found that most also have this feature (this is noted in Barringer and Bartlett, 2011). This suggests either that Canyra is also a synonym of Ugyops, or that most New World Ugyopini belongs in Canyra.
A number of species were described from females and may be difficult to place with certainty
Fennah claimed the color intensity varies greatly within a species, but the general color pattern is consistent. So far it is not clear to me that either is consistent within a species.

Molecular resources
There is limited data for Ugyops on Genbank; the Genbank data is for two (or 3) undetermined species, plus Ugyops stigmatus, Ugyops tripunctatus and U. vittatus (available here). Data for undetermined Ugyops are available on BOLD (as of this writing, 40(!) sequences, all undet species). Urban et al. (2010) sequence 4 genetic loci (18S rDNA, 28S rDNA, wingless, and cytochrome oxidase I) for Ugyops stigmatus and a Ugyops sp. (the latter from Papua New Guinea).
