Bottom Line: New or reestablished synonyms are L. dolorosa (Goeze) (= L. jucunda Reitter, = L. koltzei Reitter), L. tibialis (Voss) (= Pertorcus tibialis pilifer Voss) and L. t-album (Linnaeus) (= L. bedeli Reitter, = Baridius crocopelmus Gyllenhal, = L. sahlbergi Reitter, = L. scutellaris Reitter, = Baris t-album sculpturata Faust).Calandra uniseriata Dufour is considered a junior synonym of Sitophilus oryzae (L.) (syn. n.).A key for identification and a distribution map are provided.

ABSTRACT
The genus name Limnobaris Bedel is applied in a restricted sense to baridine weevils with a covered pygidium and non-prominent, decussate mandibles which occur on sedges in the Palaearctic Region and immediately adjacent parts of tropical Southeast Asia. Calyptopygus Marshall and Pertorcus Voss are syn. n. of Limnobaris. Some species from Africa and the Americas are maintained provisionally in Limnobaris in the widest sense but will need to be transferred to other genera in future studies. A total of eleven species is recognized in Asia, two of which are widespread and occur also in the Western Palaearctic Region. Limnobaris martensi Korotyaev sp. n. is described from Nepal. Pertorcus tibialis basalis Voss is raised to species rank, as L. basalis (stat. prom.). New or reestablished synonyms are L. dolorosa (Goeze) (= L. jucunda Reitter, = L. koltzei Reitter), L. tibialis (Voss) (= Pertorcus tibialis pilifer Voss) and L. t-album (Linnaeus) (= L. bedeli Reitter, = Baridius crocopelmus Gyllenhal, = L. sahlbergi Reitter, = L. scutellaris Reitter, = Baris t-album sculpturata Faust). Calandra uniseriata Dufour is considered a junior synonym of Sitophilus oryzae (L.) (syn. n.). A key for identification and a distribution map are provided.

Mentions: The present study is concerned with an ill-defined complex of small, slender, usually black species associated with Cyperaceae (Fig. 1). Bedel (1885) was the first to place two Western Palaearctic species in a separate genus named Limnobaris Bedel, which differs from other European baridines by having the pygidium completely covered by the elytral apices. This simple but useful character was accepted readily by contemporary entomologists: Reitter (1888) honored Bedel for his keen observation with the patronym Limnobaris bedeli; Casey (1892) adopted the concept for Nearctic species, Hartmann (1904) for an African species and Faust (1896), Champion (1908, 1909) and Hustache (1932) for Neotropical species. However, this worldwide concept no longer functioned when Casey (1920, 1922) applied new generic names to North American and Brazilian species in his private collection but ignored many others not immediately available to him. In addition to these still existing but obsolete generic placements, further problems have evolved around certain East Asian species, which currently are placed in three genera. Most share a distinct ventromedian tooth on the male protibia and all lack the dense, lateral vestiture of the type species, Limnobaris t-album (Linnaeus). Marshall (1948) described the genus Calyptopygus for a species with the above characters from the Myanmar-China border region but did not recognize its similarity to Limnobaris. Likewise, Voss (1953) described Pertorcus for a species from China’s Fujian Province, erroneously stating it has only six funicular segments. Korotyaev (1982) described Limnobaris kabakovi from Vietnam and was the first to make a connection between Limnobaris and Pertorcus, but was misled by Voss’ faulty description of the antenna. Yoshihara and Morimoto (1994) did not recognize the latent problem so Calyptopygus and Pertorcus were disregarded in their revision of East Asian Limnobaris species. Subsequent regional studies used the name Calyptopygus without providing diagnostic criteria (Yoshihara and Morimoto 1997) or their criteria made Calyptopygus and Limnobaris paraphyletic to each other (Morimoto and Yoshihara 1996, Zherikhin 1997). Kojima and Morimoto (2004) and Prena (2011) merely cataloged the status quo. The primary objective of this study is to resolve the taxonomic conflict in the current usage of the names Limnobaris, Calyptopygus and Pertorcus, and to provide a means for the identification of the species likely to be found in China. As this covers almost all known species of the genus in the restricted sense adopted herein, our results may help future students of the Limnobaris complex in other biogeographical regions.
