>I have found some references to Unionidae shells (some Hyriidae?) that I couldn't identify as valid names (see below) Probably they are outdated -or maybe mistyped- and are synonims at present. Most of them came from Uruguay. Abbreviations are from original. <
Mostly genus-level comments based on the Treatise on Invertebrate Paleontology. The unionoids have had a lot of recent work based on molecular data and new morphological studies, not all of which is at hand.
>Anodontites tenebrosicus
>Anodontites trapezialis
>Anodont. patag. (Anodonta? Anodontites? patagonica?)
>Anodont. felix
>Anodont. mortonianum
>Anodont. soleniformis
>Anodont. spixii
Anodontites is the only Anodont. bivalve genus in the Treatise in South America. It is not in Unionidae but rather Mycetopodidae. I am a bit suspicious about A. soleniformis. A (Lamproscapha) ensiformis (Spix, 1827) may have been confused with Mycetopoda soleniformis d'Orbigny, 1835.
>Castalia undosa
Castalia is in Hyriidae.
>Diplodon hyaleus
>Diplodon smithii
>Diplod. charruanus
>Diplod. paralelepipedon
>Diplod. rhuacoicus
Presumably all Diplodon (Hyriidae), but Diplodontites (Hyriidae)could be abbreviated Diplod. too.
>Monocond. corrientesensis
>Monocond. minuana
Monocondylaea would be the genus, Mycetopodidae.
>Mycetopoda legumen
>Mycetopoda silicuosa
Mycetopoda is of course the type genus for Mycetopodidae.
>Neocorbicula manilensis
>Neocorbic. limosa
Neocorbicula is a subjective synonym of Cyanocyclas, considered a subgenus of Corbicula (Family Corbiculidae, Superfamily Corbiculoidea, Subclass Heterodonta). Corbicula manilensis is a widely introduced Asian species (although some of the so-called manilensis may actually be C. leana, another Asian species) and so is not Cyanocyclas; however, C. limosa is the type of Cyanocyclas.
