The seventh Thai species of Bryocyclops Kiefer, 1927 – Bryocyclops jayabhumisp. nov. – was found in a karst cave in the Chaiyaphum Province of north-eastern Thailand. The new species differs from all previously-known species by the absence of an inner seta on the proximal endopod of the first four swimming legs. Bryocyclops jayabhumisp. nov. is most similar to B. maholarnensis Watiroyram, Brancelj & Sanoamuang, 2015 – the monotypic species of Group VII, which was previously described from Thailand. However, the new species differs from B. maholarnensis by having the following characteristics: i) posterior margin of urosomites serrated; ii) anal operculum triangular with acute-tip; iii) P1–P4Enp-1 without an inner seta; iv) armature on the female P2–P3Enp-2 and P4Enp; v) a transformed spine on the male P3Enp-2. In this study, the generic affinity of the genus Bryocyclops Kiefer, 1927 is discussed and redefined, based on the available literature concerning its principle morphology to fill the present knowledge gap about the characteristics of the genus.

Bryocyclops Kiefer属的新代表，1927年，来自泰国东北部的一个喀斯特洞穴（Copepoda，Cyclopoida，Cyclopidae），并评论了一般亲缘关系

1927年，泰国的第七种Bryocyclops Kiefer – Bryocyclops jayabhumisp。十一月 –在泰国东北部猜也蓬省的一个岩溶洞穴中被发现。新物种与所有先前已知物种的不同之处在于，前四个游泳腿的近端内足没有内set毛。苔藓。十一月 最类似于B. maholarnensis Watiroyram，Brancelj和Sanoamuang，2015年– VII组的单型物种，先前曾在泰国描述过。但是，该新物种与马氏芽孢杆菌的不同之处在于具有以下特征：i）锯齿状尾粒的后缘；ii）带有尖尖的肛门盖；iii）P1–P4Enp-1，无内部集合；iv）母P2-P3Enp-2和P4Enp的电枢；v）雄性P3Enp-2的脊柱变形。在这个研究中，
