2F5C87849829701D354BFEAE1A36F93B.taxon	discussion	Remarks Sinacroneuria aequalis sp. nov. shares a similar head pattern and sensilla basiconica patches with S. longwangshana (Yang & Yang, 1998) (compare Fig. 1 A – B with Fig. 3 A – B). However, in S. longwangshana, the aedeagal Y-stem is much shorter than the Y-arms and the basal halves of the lateral sclerites are heavily sclerotized (compare Fig. 2 A with Fig. 3 C). This new species also resembles S. lateralis Sivec & Stark, 2020 in having similar sensilla patches of tergum 10 and aedeagal sclerites (compare Figs 1 E, 2 C with Fig. 3 D – E); however, the aedeagus of S. lateralis lacks a median sclerite (compare Fig. 2 C with Fig. 3 E).	en	Liu, Rui-Jun, Cao, Zhi-Shan, Li, Wei-Hai (2025): Two new species of Sinacroneuria Yang & Yang, 1995.
