Besla is a small genus of miniature sea snails, pyramidellid gastropod mollusks in the family Pyramidellidae within the tribe Chrysallidini (sensu taxonomy by Bouchet & Roctroi, 2005).
The synonymy of Parthenina Bucquoy, Dautzenberg & Dollfus, 1883 with Besla Dall & Bartsch, 1904 proposed by Micali et al. (2012) is debatable. The type species of Besla has a protoconch axis at 90° with that of teleoconch ("type A protoconch") whereas that of Parthenina is tilted nearly 180° ("type C"); this important character suggests that they are unrelated and that their teleoconch sculpture may be convergent .
Very little is known about the biology of the members of this genus. As is true of most members of the Pyramidellidae sensu lato, they are most likely to be ectoparasites.
There are twelve known species within the genus Besla, these include:
Niech nie ide sam
Zagram ci piosenki
Napisane w snach
To czary niewinne
Me jedyne dary
Matulo kochana
Jestem tak stary
Wsioryba
Ej zabierz mnie daleko
Az po szczescia kres
Bede szedl za toba
Tak jak wierny pies
Chcialbym ci powiedziec
Troche mi zalezy
Kiedy widze ciebie
Zapominam siebie
Za ciebie I za mnie
Za zadne pieniadze
Serca nie poskapie
I juz nie zabladze
Slyszalem ze kwitnie
Na szczycie beztroski
Szczescia bezmiar wielki
I male radostki
Wsioryba
Ej zabierz mnie ze soba
Niech nie ide sam
Namaluje slonce
Potem caly swiat
Zakopie sie w tobie
I troche pomoge
Jak sercem pokarmisz
I ze mnie nie zadrwisz
Wylecze twe rany
I dla cie zaspiewam
Chcialbym ci powiedziec
Troche tu posiedze
Poczekam na ciebie
Zanim tu nie przyjdziesz
Daj mi jakis znak
