Amphibalanus sp. Figure 25a-o View Figure 25 , Table 1: species no. 91

Material examined.

Ambon Island: 1 specimen, MZB Cru Cir 135, Talake, 3°41'59.4"S, 128°10'19.2"E, coll. P. Pitriana & D. Tala, 5 Sep 2016; 1 specimen, MZB Cru Cir 136, Waitatiri, 3°37'04.0"S, 128°16'20.3"E, coll. Adin, 19 Sep 2017. Seram Island: 2 specimens, MZB Cru Cir 137, Dermaga Pelita Jaya, 3°00'13.5"S, 128°07'09.2"E, coll. P. Pitriana & D. Tala, 21 Sep 2017.

GenBank accession numbers.

COI gene (MK995349-MK995351, MK995353), 18S (MK981356-MK981358, MK981360).

Diagnosis.

Primary parietal tubes with transverse septa, exterior of shell with longitudinal striations; orifice toothed; scutum without adductor ridge; anterior margin of cirri III with conical denticles, erect hooks below posterior angles of distal articles of rami present; cirrus IV with erect hooks on posterodistal angles of articles; basidorsal of penis absent.

Description.

Shell six-plated, conical, whitish with dark purple transverse stripes (Fig. 25a, b View Figure 25 ); orifice slightly toothed; scutum trigonal, occluding margin toothed; tergum with closed spur furrow (Fig. 25c, d View Figure 25 ); mandible with five teeth (Fig. 25n View Figure 25 ); maxilla bilobed with dense setae only on lower margin (Fig. 25l View Figure 25 ). Basal length 7.4-12.2 mm, basal width 6.3-11.8 mm, height 5.5-9.4 mm; orifice length 3.6-8.3 mm; orifice width 2.6-5.9 mm (measurements for four specimens are presented in Suppl. material 1: Table S24).

Distribution.

In this study, Amphibalanus sp. was found on Ambon (at Talake and Waitatiri) and Seram islands (at Dermaga Pelita Jaya) (a map with the occurrence of Amphibalanus sp. in the Moluccas is shown in Suppl. material 1: Fig. S9).

Remarks.

In the molecular phylogeny, Amphibalanus sp. forms a well-supported clade in both, the COI and the 18S tree (Figs 28 View Figure 28 , 29 View Figure 29 ). This species also has different maxilla than those of A. amphitrite , A. reticulatus and A. variegatus , which have setae on its upper and lower margins.
