Gergithoides Schumacher, 1915 in Vietnam, with two new species, and taxonomic notes on the genus (Hemiptera: Fulgoromorpha: Issidae) Author Jérôme Constant Author Hong-Thai Pham text European Journal of Taxonomy 2017 2017-03-10 296 1 20 journal article 32062 10.5852/ejt.2017.296 6ab0c810-4a49-4a9a-8830-66e044e66255 2118-9773 894145 urn:lsid:zoobank.org:pub:F71721A1-65D9-4AC7-8877-092B76BCC76F 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. Species included G. carinatifrons Schumacher, 1915 G. caudospinosus Chen, Zhang & Chang, 2014 G. gibbosus Chou & Wang, 2003 G. gnezdilovi sp. nov. G. jejudoensis Rahman, Kwon & Suh, 2012 G. nui sp. nov. G. rugulosus (Melichar, 1906) G. undulatus Wang & Che, 2003 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.
