Description
(based on our own observations;
Boero 1980a
;
Boero
et al.
1997a
):
Hydroid.
Hydrorhizas single stolons; colonies stolonal; hydranth with conical hypostome; hydrothecae campanulate, with curved margin, usually with annular thickening and a thin membranous diaphragm, on short and annulated pedicels. Gonothecae nearly twice the length of the hydrotheca, originating from hydrorhiza, on short and annulated pedicels tapered basally, wide and truncated distally, with 4–5 opercular flaps.
Swimming gonophores:
rounded to cylindrical; manubrium reduced to a spadix, lacking a mouth; 4 radial canals; velum conspicuous; 4 atentaculate marginal bulbs; gonads on spadix.
Cnidome.
Microbasic mastigophores.
Habitat
type
.
Epiphytic on other hydroids (
Boero & Fresi 1986
;
Boero
et al.
1997a
).
Substrate.
Aglaophenia kirchenpaueri
,
A. octodonta
, and
Sertularella ellisii
.
Seasonality.
Present all year (
Boero & Fresi 1986
; De Vito 2006; Puce
et al
. 2009; this study) in the Mediterranean Sea.
Reproductive period.
June–September (
Boero & Fresi 1986
;
Peña Cantero & García Carrascosa 2002
), and April (Puce
et al
. 2009) in the western Mediterranean; January–December (see Bouillon
et al
. 2004); September–October (De Vito 2006; this study) in Salento waters.
Distribution.
Warm waters around the world (
Medel & López-González 1996
;
Boero
et al.
1997a
; Bouillon
et al.
2004;
Gravili
et al.
2008a
).
Records in Salento.
Common in the following localities: Torre dell’Inserraglio, Ponte del Ciolo (
Presicce 1991
); La Strea, Porto Cesareo (
Faucci & Boero 2000
;
Ventura 2011

et al
. 2002
; De Vito 2006; Gravili 2006;
Gravili
et al.
2008a

The whole cycle was examined in the present study.
Anthohebella parasitica
is a thecate hydroid producing an anthomedusa (for more details see
