Remarks. Based on the holotype of Sternacanista retrospinosa Tippmann, 1955 and a series of specimens from Fujian and Guangxi Provinces (Huang et al., 2015), and a series of specimens of Neacanista laosensis (Breuning, 1965) from Laos (via photographs taken by James H. Boone), we conclude that these specimens are identical and propose the following new combination and synonymy: Neacanista retrospinosa (Tippmann, 1955) comb. nov. is the valid name according to the Principle of Priority (ICZN Article 23). Since Sternacanista retrospinosa Tippmann, 1955 is the genotype, Sternacanista Tippmann, 1955 is treated as a junior synonym of Neacanista Gressitt, 1940.
According to Breuning (1965), the holotype specimen of Paracanthocinus laosensis should be 10 mm long by 4 mm wide. Regarding the type specimens, Breuning (1965) stated “Type du Laos, capturé dans la Plaine des Jarres, région de Xieng-Khouang, en Mars 1964, avec plusieurs paratypes.” We believe the specimen in the original photograph (Fig. 1E) should be considered the holotype specimen and that additional specimens from the same series should be considered paratypes. Rondon & Breuning (1970) published a more complete version of the same photograph in their figure 41g (Fig. 1F). The gender of the holotype was not mentioned and it is difficult to determine based on these two photographs. We were unable to examine the holotype which should be deposited in BPBM. There are 22 specimens in the BPBM (James H. Boone, personal communication, 2017-III-28), and the one in Figs. 1 G–J has been considered as the holotype. The holotype might have been remounted/repositioned after the photograph was taken (Figs. 1 E–F), shown in the original publication and Rondon & Breuning (1970). However, we conclude that the specimen shown in Figs. 1 G–I is not the holotype shown in the original paper, based on the black spots along the elytral suture and on the middle part of left elytron.
