Type locality. USA: Florida, Loggerhead Key , 9 ftm (16 m) ( Allman 1877: 12)  .

Material examined. Southwest Florida Shelf, middle shelf west of North Naples, 26°16.83”N, 83°23.81”W, 59.5 m, 19 July 1981, triangle dredge, on Synthecium tubithecum  , one colony with two hydrothecae, 0.6 mm high, without gonophores, coll. Continental Shelf Associates, ROMIZ B1929.

Remarks. Hebella venusta  , originally described by Allman (1877) from Loggerhead Key in the Dry Tortugas, southwest Florida, is widely distributed in tropical and subtropical regions of the western Atlantic. It ranges there from North Carolina ( Cain 1972) to the southern Caribbean Sea ( Leloup 1937) and has also been reported from Brazil ( Oliveira et al. 2016). Although the validity of H. venusta  was questioned by Boero et al. (1997), it has otherwise been recognized in multiple recent works ( Ortiz Rosado 2000; Cairns et al. 2002; Calder & Cairns 2009; Galea 2010; Calder 2013, 2015; Oliveira et al. 2016; Wedler 2017b; Mendoza-Becerril et al. 2018b; Castellanos et al. 2018; WoRMS). Characters distinguishing it from several related species worldwide were summarized by Galea (2010). Hydrothecae of the species are distinctive, and striking, in being deep and transversely annulated.

The life cycle of H. venusta  remains unknown. A free medusa seems likely, but gonophores have yet to be described. Empty gonothecae of the species were discovered and illustrated by Galea (2010) in specimens from Guadeloupe, in the Caribbean Sea.
