Bob,

The genus Guamampa according to Schileyko includes the species bulbulus, gloriosa, tuba and zodiacus (I will have to double check this as I am not near my library right now). 

Various authors have also classified these species in the genera Tricheulota and Planispira in prior years. 

MolluscaBase/WoRMS still classifies bulbulus in the genus Tricheulota along with the similar T. zodiacus among others.

P.&F. Sarasin (1899) classified these species as follows:

Planispira bulbulus with variety gloriosa forma nova
Planispira zodiacus with varieties tuba, unicolor, typica

I have to believe that the current thinking is that the species name gloriosa may not have any taxonomic ranking. Notwithstanding, it would have to be classified in the genus Tricheulota. Why the name is overlooked in both databases is another discussion...

Confusing but not surprising...

Having a hard time getting a grip on this land snail genus. It appears Aegistini, Kuroda & Habe, 1949 is the parent of Guamampa Schileyko, 1997. MolluscaBase lists one species, Guamampa tuba (Albers. 1854). In 2020 I obtained two specimens of Guamampa gloriosa (P. F. Sarasin, 1899). I added another specimen earlier this month. Is gloriosa correct, and if so, where does it belong? Any help will be welcomed.
