Fasciolariinae Gray 1853

Subfamily Fasciolariinae Gray, 1853 Diagnosis. “ Shell fusiform, medium-sized to extremely large; outer lip usually medially convex, without adapical sinus; outer-lip edge usually with paired crenulations; inner lip adherent, abapically bearing two columellar folds and a more prominent fold at entrance of siphonal canal; adaxial margin of siphonal canal often erect; siphonal process parallel to axis of coiling.” (Snyder et al. 2012: 33). Genus Aurantilaria Snyder, Vermeij & Lyons, 2012 Type species. Fasciolaria aurantiaca Lamarck, 1816; original designation by Snyder et al. (2012: 44). Present-day, northeastern Brazil to Grenadines, Lesser Antilles. Diagnosis. “ Shell medium-sized to large for subfamily, maximum length of type and largest species 211 mm; shell broadly fusiform, with relatively high spire; when fully expressed, sculpture of up to five rows of ten or more abaxially pointing nodes; other spiral sculpture of prominent cords; outer lip edge weakly convex and angled at periphery, with paired black crenulations, the termini of paired black lines on the spire and body whorl; internal lirae on adaxial side of outer lip mostly smooth, but some discontinuous toward anterior; junction of outer lip with penultimate whorl often without notch; parietal ridge prominent, rounded; entrance fold to siphonal canal prominent, rounded, more strongly expressed than the two columellar folds; folds abapical to entrance fold absent.” (Snyder et al. 2012: 45).Fasciolariinae亚科（Fasciolariinae Gray, 1853） 鉴别特征：“壳体呈纺锤形，中小型至极大；外唇通常中部凸，无近壳顶缺刻；外唇边缘通常具成对的齿状突起；内唇贴附，远壳端具2个轴唇褶，且在水管入口处具更为显著的褶；水管沟的近轴缘常直立；水管沟与螺轴平行。”（Snyder等，2012：33） Aurantilaria属（Aurantilaria Snyder, Vermeij & Lyons, 2012） 模式种：Fasciolaria aurantiaca Lamarck, 1816；由Snyder、Vermeij与Lyons（2012：44）首次指定为该属模式种。 现生分布范围：巴西东北部至小安的列斯群岛格林纳丁斯群岛。 鉴别特征：“该亚科下的中小型至大型壳体，模式种及最大物种的最大体长可达211毫米；壳体呈宽纺锤形，螺旋部相对较高；壳饰发育完全时，具最多5列结节，每列含10个以上指向远壳端的突起；其余螺旋状壳饰为显著的螺肋；外唇边缘弱凸，在周缘处呈角状，具成对黑色齿状突起，对应壳顶螺层和体螺层上成对黑线的末端；外唇近轴侧的内部褶纹大多光滑，前部部分不连续；外唇与次体螺层的连接处通常无缺刻；胼胝脊显著且圆润；水管入口处的褶显著且圆润，较2个轴唇褶更为发达；水管入口褶的远壳端无其他褶。”（Snyder等，2012：45）
