Aglaophenia curvidens Fraser, 1937b 

Aglaophenia curvidens Fraser, 1937b: 3  , pl. 1, figs. 5a–c.

Holotype. USNM 43289View Materials: Puerto Rico, northeast coast off Cabo San Juan, Johnson-Smithsonian Deep-Sea Expedition Sta. 75, 18°27’35”N, 65°33’35”W, 25 February 1933, 48 m, R/ V Caroline, one colony, 2.6 cm high, in fairly good condition, without gonophores, collGoogleMaps  . Paul Bartsch, labelled “ type ” and “ holotype ”; ethanol. 

Paratypes. BCPMAbout BCPM 976-00770-001: Puerto Rico, north coast, Johnson Hydro Sta. 75, 25 February 1933, two colony fragments, in only fair condition, without gonothecae, labelled “co-type”; 60% IPAAbout IPA.

Type locality. Puerto Rico: 18°27’35”N, 65°33’35”W, 26 fm (48 m) ( Bartsch 1933, Sta. 75; Fraser 1937b).

Current status. Valid.

Remarks. Aglaophenia curvidens  was taken by tangle off Cabo San Juan, northeastern Puerto Rico, during the Johnson-Smithsonian Deep-Sea Expedition (Station 75). Fraser’s holotype of the species is currently listed as a syntype in the NMNHAbout NMNH online database ( USNMAbout USNM 43289), although the specimen count is given as “1”. That specimen, examined here, indeed comprises a single colony. Other material, labelled “co-type”, exists at the RBCMAbout RBCM ( BCPMAbout BCPM 976-00770-001). It is included above as a paratype.

The hydroid described by Fraser (1937b) was sterile. Its specific name refers to the striking inward curve of the marginal cusps on the hydrothecal rim. Aglaophenia curvidens  is currently listed as valid in WoRMS, although Bogle (1975) regarded it as probably identical with Macrorhynchia robusta ( Fewkes, 1881)  . Fraser (1944a) distinguished the two species based on purported differences in the morphology of their marginal cusps, which were said to be straight in M. robusta  (= Aglaophenia robusta  ) and strongly recurved in A. curvidens  . We have followed his concept that the two are distinct. The species is known only from the original description, although non-type specimens identified as Aglaophenia cf. curvidens  from northern Florida, USA, exist in the NMNH (USNM 59441).
