Gergithoides Schumacher, 1915

Jérôme Constant & Hong-Thai Pham, 2017, Gergithoides Schumacher, 1915 in Vietnam, with two new species, and taxonomic notes on the genus (Hemiptera: Fulgoromorpha: Issidae), European Journal of Taxonomy 296, pp. 1-20 : 4

Genus Gergithoides Schumacher, 1915

Gergithoides Schumacher, 1915: 126 . Type species: Gergithoides carinatifrons Schumacher, 1915 by monotypy.

Daruma Matsumura, 1916: 103 (preoccupied). Type species: Daruma nitobei Matsumura, 1916 , by original designation. Synonymized by Ishihara (1965a: 208) under the erroneous spelling “ Darma ”.

Darumara Metcalf, 1952: 227 . New name for Daruma Matsumura, 1916 . Synonymized by Gnezdilov (2009: 85) [erroneous: already synonymized by Ishihara (1965a)].

Darma Ishihara, 1965a: 208. Misspelling of Daruma .

We follow the definition of the genus given in the key to the genera of Hemisphaeriini proposed by Sun et al. (2012), with the following distinctive set of characters: (1) posterior wing longer than half length of tegmen; (2) frons with complete median carina; (3) lateral margins of frons not elevated and (4) a row of tubercles along lateral margin of frons.

Note

Ishihara (1965a) was the first to propose Daruma as a junior synonym of Gergithoides , although he should have used the name Darumara as proposed by Metclaf (1952). It seems that Chan & Yang (1994) were not aware of Ishihara’s (1965a) synonymy, as they considered Gergithoides and Darumara as separate genera. More recently, Gnezdilov (2009) reinstated Ishihara’s (1965a) view but erroneously stated that he proposed a new synonymy instead.

Remarks

The species of Gergithoides should be identified based on the comparison of the male genitalia with reliable illustrations. Considering the numerous pending issues regarding the identity of the species of Gergithoides , it is currently unwise to propose an identification key to the species.
