对 Apogonidae 科的两个物种（Cercamia eremia [Apogoninae] 和 Pseudamia gelatinosa [Pseudamiinae]）的侧线系统及其神经支配进行了检查。这两个物种的特征都是具有大量浅表神经丘（SN；麻蚁麻疹总数 2,717 个；胶状麻蚁 9,650 个），包括躯干背半部和腹侧半部的行，与 1 个（麻蚁麻）和 3 个（明胶麻）缩小的躯干管相关。 SN 神经支配模式清楚地表明，SN 分布的总体模式在两个物种中趋同进化。因C.在麻血病中，整个躯干上的 SN 行由背侧纵向收集神经 (DLCN) 的细长分支（前方）和外侧支（后方）支配。 InP。 gelatinosa 中，DLCN 的神经支配模式反映在躯干的腹侧半部（腹侧纵向收集神经：VLCN）。 DLCN 和 VLCN 的细长分支分别支配躯干背半部和腹半部的 SN 行。干管的减少显然与 SN 的增加没有直接关系，因为这些分支起源于侧线鳞片深处，鳞片表面没有支配神经管神经丘 (CN) 同源物。 InP。 gelatinosa 的每一个小侧线鳞片上都出现一个 CN（或一个 SN 行：CN 同源物），而同源物（P. hayashiii 和 P. zonata）的每一个大侧线鳞片上都有一个 SN 行（CN 同源物）。
The lateral line system and its innervation were examined in two species of the family Apogonidae (Cercamia eremia[Apogoninae] andPseudamia gelatinosa[Pseudamiinae]). Both species were characterized by numerous superficial neuromasts (SNs; total 2,717 inC. eremia; 9,650 inP. gelatinosa), including rows on the dorsal and ventral halves of the trunk, associated with one (inC. eremia) and three (inP. gelatinosa) reduced trunk canals. The pattern of SN innervation clearly demonstrated that the overall pattern of SN distribution had evolved convergently in the two species. InC. eremia, SN rows over the entire trunk were innervated by elongated branches of the dorsal longitudinal collector nerve (DLCN) anteriorly and lateral ramus posteriorly. InP. gelatinosa, the innervation pattern of the DLCN was mirrored on the ventral half of the trunk (ventral longitudinal collector nerve: VLCN). Elongated branches of the DLCN and VLCN innervated SN rows on the dorsal and ventral halves of the trunk, respectively. The reduced trunk canal(s) apparently had no direct relationship with the increase of SNs, because these branches originated deep to the lateral line scales, none innervating canal neuromast (CN) homologues on the surface of the scales. InP. gelatinosa, a CN (or an SN row: CN homologue) occurred on every other one of their small lateral line scales, while congeners (P. hayashiiandP. zonata) had an SN row (CN homologue) on every one of their large lateral line scales.
