对淡水半喙翅目昆虫的侧线系统及其神经支配进行了研究，发现其适应了一种表面昆虫的食性。浅层神经肥大(SNS)分布于头部(下颌骨腹面、口鼻、面颊、颞上区和穹隆)、躯干(形成四列纵行：背中、背外侧、外侧和腹外侧排)和尾鳍(两排)。背中线较宽，累及躯干前方的3个纵向鳞片(背中和左右相邻)，包括809个SNN(左侧计数)，每个鳞片上可达108个SNN形成不同程度的新月状斑块。后外侧线神经(PLLN)的额上支(PLLN)强烈地向后延伸，支配背中行。(PLLN)外侧支发出1支支配背外侧排的前背侧支，4支支配外侧排的腹侧短枝，15支长的腹侧支支配腹外侧排的SN和主干侧线的管神经肥大。
Examination of the lateral line system and its innervation in a freshwater halfbeak,Zenarchopterus dunckeri(Beloniformes: Exocoetoidei: Zenarchopteridae), revealed adaptations of a surface insect feeder. Superficial neuromasts (SNs) occurred on the head (ventral surface of lower jaw, snout, cheek, supratemporal region and opercle), trunk (forming four longitudinal rows: middorsal, dorsolateral, lateral and ventrolateral rows) and caudal fin (two rows). The middorsal row was broad, involving three longitudinal scale series (middorsal and left and right adjacent series) anteriorly on the trunk and including 809 SNs (counted on the left side); up to 108 SNs formed a more or less crescentic patch on each scale. The supratemporal ramus of the posterior lateral line nerve (PLLN) extended strongly posterior to innervate the middorsal row. The lateral ramus (of PLLN) gave off an anterior dorsal ramule innervating the dorsolateral row, four short ventral ramules innervating the lateral row, and 15 long ventral ramules innervating SNs of the ventrolateral row and canal neuromasts of the trunk lateral line.
