The echinoid Homolampas fragilis (A. Agassiz,1869) (Echinodermata) is recorded for the first time in the Brazilian coast from the Continental shelf of the State of Ceará. The specimens were classified based on their distinct morphological characters, including the fragile test, primary tubercles non-crenulated and with deep areoles, absent peripetalous fasciole, without aboral tubercles on the interambulacrum 5, three to four genital pores, and posterior prolongation of the labrum, not reaching the second adjacent labral plate narrow and wedge-shaped, extending to second or third ambulacral plate; only just contacting sternal ambulacral plates. This species usually inhabits tropical waters from the Caribbean Sea, Gulf of Mexico, and Florida Strait. Its bathymetry is expanded from 360–3550 to 34–3550 m deep. In the present work, we provide morphological and geographical updates on Homolampas fragilis found in the Brazilian coast.

来自巴西海岸的心脏顽童Homolampas fragilis（A。Agassiz，1869年）（Echinoidea：Echinodermata）

脆弱类棘突类Ho虫（A. Agassiz，1869）（Echinodermata）首次在巴西海岸的塞阿拉州大陆架上被记录下来。根据标本的独特形态特征对标本进行分类，包括易碎性试验，无齿状的原发结节和深部的小孔，不具剑突的筋膜，第5、3至4个生殖器孔，无侧唇的延长，未达到第二相邻的窄窄楔形的唇板，延伸至第二或第三腓骨板；仅接触胸骨乳bul板。该物种通常居住在加勒比海，墨西哥湾和佛罗里达海峡的热带水域。其水深从360–3550扩大到34–3550 m。在目前的工作中，在巴西海岸发现脆弱的霍莫拉帕玛斯。
