Here we present the taxonomy of the cheilostome genera Adeonellopsis MacGillivray, 1886 and Reptadeonella Busk, 1884 in Brazil. Of the six species previously reported in Brazilian waters, we include redescriptions of Adeonellopsis subsulcata (Smitt, 1873), Reptadeonella bipartita (Canu & Bassler, 1928) and Reptadeonella costulata (Canu & Bassler, 1928). Four new species of Reptadeonella are described: Reptadeonella aspera n. sp., Reptadeonella brasiliensis n. sp. (previously misidentified as Reptadeonella violacea), Reptadeonella cucullata n. sp. and Reptadeonella leilae n. sp. Reptadeonella aspera n. sp., from Bahia State, is characterized by rugose frontal calcification, a tubular peristome, small suboral avicularium and elliptical spiramen. Reptadeonella brasiliensis n. sp. is the commonest intertidal species in NE Brazil; it is distinguished from other Brazilian Reptadeonella in having a nodular peristome, large subperistomial areolar pore and zooids with one or two frontal pores frequently replaced by a suboral avicularium and crescentic spiramen. Reptadeonella cucullata n. sp., from Espírito Santo and Bahia states, has a hood-like peristome, large subperistomial areolar pore, suboral avicularium with curved mandible and denticulate spiramen. Reptadeonella leilae n. sp., described from Bahia State, has a frontal shield with small granules, tubular peristome, semilunar to semicircular subperistomial areolar pore and circular spiramen. Diagnostic characters of Reptadeonella species are discussed.
在此，我们展示了巴西唇口目艾氏苔藓虫属（Adeonellopsis MacGillivray，1886年）和拟蜥苔藓虫属（Reptadeonella Busk，1884年）的分类学研究。在先前报道于巴西海域的6个物种中，我们对浅沟艾氏苔藓虫（Adeonellopsis subsulcata，斯密特，1873年）、二分拟蜥苔藓虫（Reptadeonella bipartita，卡努和巴斯勒，1928年）以及肋状拟蜥苔藓虫（Reptadeonella costulata，卡努和巴斯勒，1928年）进行了重新描述。此外，还描述了4个拟蜥苔藓虫新物种：粗糙拟蜥苔藓虫（Reptadeonella aspera）新种、巴西拟蜥苔藓虫（Reptadeonella brasiliensis）新种（此前被误鉴定为紫色拟蜥苔藓虫）、兜状拟蜥苔藓虫（Reptadeonella cucullata）新种以及莱拉拟蜥苔藓虫（Reptadeonella leilae）新种。来自巴伊亚州的粗糙拟蜥苔藓虫新种的特征为额部钙化粗糙、口围呈管状、口下鸟头体小且螺旋孔呈椭圆形。巴西拟蜥苔藓虫新种是巴西东北部最常见的潮间带物种；它与巴西的其他拟蜥苔藓虫的区别在于口围呈结节状、围口部乳晕孔大，且个虫具有一两个额孔，常被口下鸟头体和新月形螺旋孔取代。来自圣埃斯皮里图州和巴伊亚州的兜状拟蜥苔藓虫新种的口围呈兜状、围口部乳晕孔大、口下鸟头体的下颌弯曲且螺旋孔具细齿。来自巴伊亚州的莱拉拟蜥苔藓虫新种的额部盾板有小颗粒、口围呈管状、围口部乳晕孔呈半月形至半圆形且螺旋孔呈圆形。文中还讨论了拟蜥苔藓虫属物种的鉴别特征。
