Sertularia brevis Fraser, 1935b

Sertularia minuta Hargitt, 1924: 494 , pl. 5, fig. 18 [invalid junior primary homonym of Sertularia minuta Bale, 1882 ].

Sertularia brevis Fraser, 1935b: 110 , pl. 2, fig. 9 [replacement name for Sertularia minuta Hargitt, 1924 ; not Sertularia minuta Bale, 1882 ]

Dynamena brevis .— Yamada, 1959: 58.

Syntypes. USNM 42652 : Philippines, Bataan, Luzon Island, Mariveles , 14°25’48”N, 120°28’48”E, 0 6 June 1912, several colony fragments (as Sertularia minuta Hargitt, 1924 ); slide.

Lectotype, by present designation. USNM 42652 : Philippines, Bataan, Luzon Island, Mariveles , 14°25’48”N, 120°28’48”E, 0 6 June 1912, one colony fragment, in good condition, with a gonotheca (as Sertularia minuta Hargitt, 1924 ); slide; see Remarks below.

Paralectotypes. USNM 42652: Philippines, Bataan, Luzon Island, Mariveles, 14°25’48”N, 120°28’48”E, 0 6 June 1912, several colony fragments, in good condition, two with gonothecae (as Sertularia minuta Hargitt, 1924 ); same slide as lectotype.

Type locality. Philippines, Bataan: Luzon Island , Mariveles.

Current status. Valid, as Dynamena brevis ( Fraser, 1935b) .

Remarks. Hargitt (1924) provided a station number (697) in his account of Sertularia minuta from the Philippines, but gave no other collection data to accompany it. Information on the type locality above is taken from the NMNH record of Hargitt’s syntype specimens (USNM 42652). The coordinates of the site point to a location on dry land.

Several colony fragments exist on the syntype slide (USNM 42652) of Hargitt’s (1924) Sertularia minuta . These may or may not have been part of the same colony. Therefore, one in the NW quadrant, having a gonotheca containing a gonophore, is designated here as the lectotype. Others on the slide are paralectotypes.

Nutting (1927: 213) noted the homonymy between Sertularia minuta Hargitt, 1924 and S. minuta Bale, 1882 , but did not provide a replacement name for the junior name. Fraser (1935b) proposed S. brevis as a nomen novum for Hargitt’s species, now assigned to Dynamena Lamouroux, 1812 , as D. brevis (e.g., Yamada 1959; Hirohito 1995; Tseng et al. 2014; WoRMS). Meanwhile, Sertularia minuta Bale, 1882 has been referred to Amphisbetia L. Agassiz, 1862 , as A. minuta .
