A comprehensive review and analysis of the literature on echinoids from Sri Lankan waters were conducted to compile an annotated list that integrates the existing published data with original data from recent research. According to the published literature, 115 echinoid species and one subspecies have been reported from Sri Lanka to date. However, the current study revealed that only 66 echinoid species and one subspecies belonging to 20 families can be verified to occur in Sri Lankan waters. According to the present analysis, 49 species were excluded from the list due to uncertain records (16) or synonymy (33) with other taxa known from the region. Of the 66 species and one subspecies occurring in Sri Lankan waters, 11 were first described from type material collected from this region. Six of the type specimens are "regular" echinoids and five are Irregularia. Out of these 11, Araeosoma coriaceum indicum has been recorded only from and appears to be endemic to Sri Lankan waters. However, 34 species of Sri Lankan echinoids have not been recorded in the last 90 years. Echinoid species recorded from Sri Lankan waters represent 6.7% of the currently accepted species of extant echinoids and include representatives of 28% of the extant echinoid families. Forty-five percent (45%) of echinoids recorded from the Indian coast (113 species and subspecies) are present in Sri Lankan waters. The current study highlights the need for systematic revision of echinoid records in Sri Lanka through field surveys and reconciliation of discrepancies in the existing literature. Offshore sampling is also needed due to lack of recent information on local deep-sea echinoids.
对来自斯里兰卡海域的海胆类文献进行了全面的综述和分析，以编制一份注释清单，将现有的已发表数据与近期研究的原始数据整合在一起。根据已发表的文献，迄今为止，从斯里兰卡已报道了115种海胆类物种和1个亚种。然而，当前的研究表明，在斯里兰卡海域仅能证实有属于20个科的66种海胆类物种和1个亚种存在。根据目前的分析，由于记录不确定（16种）或与该地区已知的其他分类单元同义（33种），有49种被从清单中排除。在斯里兰卡海域出现的66种物种和1个亚种中，有11种是首次根据从该地区采集的模式标本描述的。其中6个模式标本是“规则”海胆类，5个是“不规则”海胆类。在这11种中，印度革海胆指名亚种仅在斯里兰卡海域有记录，似乎是该海域特有的。然而，有34种斯里兰卡海胆类在过去90年中未被记录。从斯里兰卡海域记录的海胆类物种占目前公认的现存海胆类物种的6.7%，包括现存海胆类科的28%的代表。从印度海岸记录的海胆类（113种和亚种）中有45%存在于斯里兰卡海域。当前的研究强调需要通过实地调查和协调现有文献中的差异，对斯里兰卡的海胆类记录进行系统修订。由于缺乏关于当地深海海胆类的最新信息，还需要进行近海采样。
