Guembelina pseudotessera Cushman, 1938 is the type species of Tesseraella Aliyulla, 1977 (a subjective junior synonym of Spiroplecta according to L&T). If it is to be accepted under Praegublerina then Praegublerina should be considered as a subjective junior synonym of Tesseraella (reinstated).
Merry Christmas & Happy new year,
Thanks for pointing that out. Actually though the species Praegublerina pseudotessera has been deleted from the working taxonomy and you managed to get to the deleted entry -so this is a mostly case of me needing to clean up the program code to avoid non-editors viewing deleted taxa.
