Natatolana angula Bruce, 1986  

Natatolana angula Bruce, 1986: 106   , fig. 73.–Springthorpe & Lowry, 1994: 37.– Brusca et al., 1995: 79.–Keable, 1997: 255, fig. 1e.– Bruce et al., 2002: 149.

Natatolana cf. angula   .– Keable, 1995: 43.

Type material. Holotype: 3, QM W9795. Paratypes: QM W9797-9800; AM P32380 View Materials (examined)   ; USNM; NTM. Type locality: Halifax Bay , Townsville, Queensland, Australia, 19°08'S 146°19'E GoogleMaps   .

Material examined. Listed by Keable (1997).

Diagnosis. Interocular furrow: well developed, extending across the cephalon; smoothly convex. Frontal lamina: lateral margins medially constricted. Antenna: c. 0.4× as long as body, reaching to between the posterior of pereonite 3 and 4 (pereonite 2 according to Bruce (1986), however, in one paratype from AM P32380 View Materials it reaches to the posterior of pereonite 3 and in the other it reaches to one third of the way along pereonite 4). Coxal plates: furrows moderately developed, on all coxae. Pleonite 4: apex slightly rounded. Pleotelson: broad, length 0.76× basal width; anterodorsal depression absent; anterolateral margins almost straight and angling posteriorly toward the midline; posterolateral margins straight, markedly angled to anterolateral margins and meeting at an obtuse angle or convex (on paratypes the posterior margin appears straight); apex not produced, lateral margins converging smoothly to a point; with 8–12 RS. Pereopods 2–3: propodus without RS on palm. Pereopod 7: basis broad, width 0.58× length; distance between anterior margin and medial carina greater than between posterior margin and medial carina; posterior margin with setae along entire length. Penes: absent. Pleopod 2 appendix masculina: just shorter than endopod; margins very slightly curved laterally or straight; slender; apex not at angle to adjacent margins, bluntly rounded. Uropods: exopod slightly shorter than endopod, 0.87× the length of the endopod.

Size. Adults to 13.5 mm.

Remarks. Identification, distribution, ecology and character variation for Natatolana angula   is discussed by Keable (1997) who also re-illustrated the uropod.

Distribution and ecology. Australia: northern Western Australia, Darwin (Northern Territory), northern Queensland south to Gladstone. Hayward et al. (2001) report “ Notatolana [sic] ‘ angula   ’” from New Zealand, this requires confirmation. Intertidal to 83 m depth. Scavenger.
