This study describes Henneguya sacacaensis n. sp. in specimens of the Osteichthyes Satanoperca jurupari (Heckel, 1840), collected in the Rio Curiaú Environmental Protection Area in the city of Macapá, state of Amapá Brazil. Using optical microscopy and molecular analysis, these cyst-shaped parasites were analyzed. The gills of 57.14% of the analyzed S. jurupari contained hundreds of spores. The cysts found on the gill lamellae were oval-shaped and whitish. The Henneguya spores had an average length of 46.5 (41.3-56.92) µm. The fusiform body of the Henneguya measured 16.5 (13.16-20.01) µm long and 5.1 (3.91-6.12) µm in width, the two polar capsules had a taper of 3.83 (3.4-4.32) µm and a width of 1.68 (1.4-1.99) µm, and the tail measured 30 (22.47-41.67) µm in length, containing a polar filament coiled seven to nine times. Morphogical and phylogenetic analysis allowed the preposition of a new species, Henneguya sacacaensis n. sp, that belongs to the family Myxobolidae and the genus Henneguya.
本研究描述了在巴西阿马帕州马卡帕市库里阿乌河环境保护区采集的鲈形目鱼类撒旦丽鱼（Heckel，1840）标本中的萨卡卡亨内古亚新种。利用光学显微镜和分子分析对这些囊肿状寄生虫进行了分析。在57.14%的被分析撒旦丽鱼的鳃中发现了数百个孢子。在鳃小片上发现的囊肿呈椭圆形，颜色发白。亨内古亚孢子的平均长度为46.5（41.3 - 56.92）µm。亨内古亚的梭形主体长16.5（13.16 - 20.01）µm，宽5.1（3.91 - 6.12）µm，两个极囊的锥度为3.83（3.4 - 4.32）µm，宽度为1.68（1.4 - 1.99）µm，尾部长30（22.47 - 41.67）µm，包含一条盘绕七至九次的极丝。形态学和系统发育分析确定了一个新物种，即属于粘体科和亨内古亚属的萨卡卡亨内古亚新种。
