Two new species of Catoptrus A. Milne-Edwards, 1870, Catoptrus quinquedentatus sp. nov. and Catoptrus undulatipes sp. nov. (Portunidae, Carupinae), are described from the South China Sea, and their affinities with allied taxa are discussed. RÉSUMÉ Deux espèces nouvelles de Catoptrus A.

Background. Preoperative eye-covering training for 3 hours has been reported to e ectively reduce the incidence of emergence delirium (ED) in preschool children. However, most children can only maintain the eye being covered for less than 60 min, and shortening eye-covering duration can also achieve similar clinical e ects as long duration of eye-covering. is study was designed to compare the e ects of 30-min and 60-min eye-covering pretreatment based on cartoon education only on preoperative anxiety, postoperative ED, and pain score after ophthalmic surgery with general anesthesia in preschool-aged children. Methods. Preschool-aged children (3-7 years) who were diagnosed with cataract, blepharoptosis, trichiasis, strabismus, eyelid tumor, and underwent ophthalmic surgery with general anesthesia from August 2021 to January 2022 were recruited. A total of 228 patients were randomly assigned at a 1 : 1:1 ratio to receive 30-min eye covering (30-min group), 60-min eye covering (60-min group) pretreatment, or programmed education only (C group). e preoperative anxiety, postoperative emergence delirium, and pain were compared between the groups. Results. e preoperative anxiety score, postoperative ED score, and incidence of ED in the 30-min group (n 76) and 60-min group (n 72) were signi cantly lower than those in the C group (n 76), demonstrating a signi cant between-group di erence (P < 0.001). However, the 30-min group and 60-min group had no signi cant di erence in the abovementioned outcome measures (P > 0.05). Moreover, no signi cant di erence was found in postoperative pain scores among the three groups (H 0.274, P 0.872). Conclusion. Both 30-min and 60-min eye-covering pretreatments signi cantly reduce preoperative anxiety and postoperative ED after ophthalmic surgery with general anesthesia in preschool-aged children.e e ects of the two groups show no intergroup di erence, but the 30-min eye-covering pretreatment may be more convenient for practicing. Trial Registration. is study was registered with the No. NCT04973150.
