Genera in the family or subfamily Geotriidae: [ 10 ] records

Chilopterus Philippi [R. A.] 1858:308 Masc. Ammocoetes caeruleus Philippi 1858. Type by subsequent designation. Apparently two included species (caeruleus and landbecki), earliest subsequent designation not researched; type as listed by Fowler 1964:32 [ref. 7160]. Based on larval specimens. Ammocoetus would be the correct spelling for the genus of the type species. •Treated as a genus inquirendum in Geotriinae by Kullander & Fernholm in Reis et al. 2003:12 [ref. 27061]. •Synonym of Geotria Gray 1851 -- (Renaud 2011:16 [ref. 31770]). Current status: Synonym of Geotria Gray 1851. Geotriidae.

Dionisia Lahille [F.] 1915:374, 380 Fem. Dionisia patagonica Lahille 1915. Type by monotypy. Proposed on p. 374 as distinguished provisionally from Geotria chilensis and in the synonymy of G. chilensis on p. 380. Evidently missed by authors until Hubbs & Potter 1971, but perhaps not available since Dionisia can be considered as a name published in synonymy and species not separately distinguished from G. chilensis and not treated as valid. •Synonym of Exomegas Gill 1883 -- (Lacoste et al. 2021:[3] [ref. 38542]). •Synonym of Geotria Gray 1851 -- (Hubbs & Potter 1971:55 [ref. 13397], Kullander & Fernholm in Reis et al. 2003:11 [ref. 27061]). Current status: Synonym of Geotria Gray 1851. Geotriidae.

Exodomegas Gill [T. N.] 1883:524 Masc. Not available; manuscript name published in synonymy of Exomegas Gill 1883 and apparently never made available by later use. Nomen Nudum. Geotriidae.

Exomegas Gill [T. N.] 1883:524 Masc. Petromyzon macrostomus Burmeister 1868. Type by original designation (also monotypic).

Current status: Synonym of Geotria Gray 1851. Geotriidae.

Thysanochilus Philippi [R. A.] 1857:268, footnote Masc. Thysanochilus valdivianus Philippi 1857. Type by monotypy.

[Article not translated; status unclear but probably unavailable; authorship perhaps Troschel in Philippi.] •Synonym of Geotria Gray 1851 -- (Kullander & Fernholm in Reis et al. 2003:11 [ref. 27061], Renaud 2011:16 [ref. 31770]).
