Description Cell is small- to relatively large-sized and is somewhat isodiametric. In ventral view, the shape is irregularly pentagonal and convex. The cell frequently has one or two shoulders that may or may not be very noticeable. The hypotheca is irregularly trapezoidal with convex and sometimes irregular sides. A concavity may be located on the left side of the hypotheca; sometimes a protuberance is above it. This concavity is not deep, but it is noticeable. The posterior margin is very often asymmetric, sloped forwards and to the right. The descending (1) cingulum is excavated and has a very narrow list. The sulcus is variably deep and has moderately developed lists. The PO is often very wide and markedly angular. Its dorsal margin is relatively extensive and is more often straight or nearly straight, but it is sometimes regular or irregularly convex. Commonly, the right margin is composed of two segments. The dorsal segment is usually straight or almost straight but is sometimes regularly or irregularly convex and parallel to the major axis of the plate. The ventral segment is sloped inward and is straight or rather concave. The ventral end is almost always fully truncated and forms a clear connection with 1'. Rarely, a PO is found that has a laterally located connecting pore that is almost always small (several were found in material from Norway [Oslo]). Small marginal pores were detected in the PO of thecae from England (Cornwall) and Korea. The 1' has a relatively variable width. Usually, the anterior angle and, especially, the posterior angle are rather extensively truncated. The anterior right margin is often rather concave. Sometimes, the margin is abruptly angled at the location of the ventral pore. Occasionally, the two larger margins are straight. The ventral pore is small and always exists. Both its position on. the margin and the degree of its indentation on the plate may vary. For example, the notch frequently occurs mostly within the suture region and penetrates only a little or not at all onto the plate. In other cases, the pore may be formed by two conjugated notches, one in 1' and the other in 4'. In some individuals, the notch is in the 4' plate, completely or almost completely. In this latter circumstance, the pore would be missed if the observer examined only the 1 '. 3' is always clearly asymmetrical, but the degree of asymmetry varies. 1 """" is somewhat narrow. The most variable feature is the development of the left sulcal list, which is rather wide in some cases and rather narrow in others. The right sulcal list, supported by the 5""' plate, is usually barely conspicuous. 2"""" is variable. It is transversely extended in some thecae (type B) or dorsoventrally in others (type A), with some in transition. Type B is dominant and is the type represented in Lebour's description. However, the transition forms occur frequently. The sulcal plates also vary. The S.a. is always narrow, is generally a little longer than wide, and has a deep posterior sinus. The anterior margin is more or less straight, wide, and situated at or a little above the level of the anterior left margin of the cingulum. In Lebour's figure, the anterior margin clearly intrudes onto the epitheca. From the left side of this margin, a short and oblique groove is directed to the right and down. Frequently, a portion of this margin, usually the right part but sometimes the left part, is lifted more or less abruptly and penetrates into the epitheca, sometimes quite deeply. This may be a kequent and rather noticeable characteristic in cultured specimens, but it is rare in field specimens. The S.p. may or may not have a connecting pore that is small, clearly displaced to the right, and connected to the edge by a groove. Sometimes, a groove occurs without a pore; many thecae have neither, as is the case for most of those from the Argentine Sea. The length/width relation of this plate is somewhat variable. Of the remaining sulcal plates, the most variable [details]
Harmful effect For a discussion of the species in the tamarense group, see under A. catenella. John et al. (2014) have suggested that the name A. tamarense be applied to isolates belonging to Group II. With this concept A. tamarense would be a harmless species.
Only a strain (CNR-ATA6PT) from Sardinia was reported to have GTX (Gonyautoxins) once analysed by high pressure liquid chromatography coupled to a mass spectrometry (HPLC/MS) (Lugliè et al. 2017). [details]
Identification This species, belonging to the Alexandrium tamarense species complex, can only be unambiguously identified using genetic techniques. [details]
