This species is similar to Halolaguna sanmaru Park, 2011 in the male genitalia, but can be separated from it by the valva with a strong apical spine, the juxta with postero-lateral lobes about 1/2 length of the juxta, and the aedeagus with a pointed apex (Fig. 3d). In Halolaguna sanmaru , the valva does not bear an apical spine, the postero-lateral lobes of the juxta are slightly longer than the juxta, and the aedeagus is rounded apically. This species is also similar to Halolaguna discoidea sp. n. in the female genitalia, but can be separated from it by the eighth sternite with caudal margin slightly concave at middle, and the ductus seminalis as broad as the ductus bursae (Fig. 4c). In Halolaguna discoidea sp. n., the caudal margin of the eighth sternite is deeply concave in U shape medially, and the ductus seminalis is slenderer than the ductus bursae. Distribution. China (Chongqing, Fujian, Guangxi, Sichuan, Taiwan, Yunnan, Zhejiang).
