Fifteen Recent species and three Miocene species of Rhysodini (Coleoptera: Carabidae: Scaritinae) are named and described as new species: Yamatosa phuka (Thailand), Arrowina nan (Thailand), Arrowina taksar (Nepal), Omoglymmius (Omoglymmius) truncatus (Thailand). Omoglymmius (Omoglymmius) batantae (Irian Jaya). Rhyzodiastes (Temoana) orestes (Tibet), Rhyzodiastes (Rhyzostrix) ininius (Guyane), Rhyzodiastes (Rhyzostrix) exsequiae (Brazil), Clinidium (Clinidium) ashei (Panama), Clinidium (Clinidium) brusteli (Ecuador), Clinidium (Clinidium) chandleri (Costa Rica), Clinidium (Clinidium) dux (Philippines), Clinidium (Clinidium) erwini (Costa Rica), Clinidium (Clinidium) felix (Panama), and Clinidium (Clinidium) talamanca (Costa Rica) , and the Dominican Republic amber fossils, Clinidium (Clinidium) poinari. Plesioglymmius (Ameroglymmius) zayasi, and Clinidium (Tainoa) grimaldii. The males of Rhyzodiastes (Temoana) denticauda R. Bell and J. Bell and Clinidium (Clinidium) segne R. Bell and J. Bell, previously known only from females, are described. The females of Yamatosa schawalleri R. Bell and J. Bell and Clinidium (Clinidium) impressum R. Bell and J. Bell, previously known from males, are described. Range extensions or clarifications are given for the following 30 species: Leoglymmius lignarius (Ollift). Medisores abditus R. Bell and J. Bell, Dhysores thoreyi (Grouvelle), Rhysodes sulcatus Fabricius, Yamatosa boysi (Arrow), Yamatosa reitteri (Bell), Yamatosa sinensis R. Bell and J. Bell, Plesioglymius (Juxtaglymmius) jugatus R. Bell and J. Bell, Omoglymmius (Orthoglymmius) cavifrons (Grouvelle), Omoglymmius (Orthoglymmius) crenatus (Grouvelle), Omoglymmius (Omoglymmius) laticeps R. Bell, Omoglymmius (Omoglymmius) germari Ganglbauer, Omoglymmius (Omoglymmius) vicinus (Grouvelle), Grouvellina tubericeps (Fairemaire), Grouvellina radama R. Bell and J. Bell, Rhyzodiastes (Temoana) preorbitalis R. Bell and J. Bell, Rhyzodiastes (Temoana) denticauda R. Bell and J. Bell, Clinidium (Mexiclinidium) championi R. Bell and J. Bell, Clinidium (Mexiclinidium) newtoni R. Bell and J. Bell, Clinidium (Clinidium) centrale Grouvelle, Clinidium (Clinidium) granatense Chevrolat, Clinidium (Clinidium) insigne Grouvelle, Clinidium (Clinidium) integrum Grouvelle, Clinidium (Clinidium) jolyi R. Bell and J. Bell, Clinidium (Clinidium) mathani Grouvelle, Clinidium (Clinidium) moldenkei R. Bell and J. Bell, Clinidium (Clinidium) oberthueri Grouvelle, Clinidium (Clinidium) rossi R. Bell, Clinidium (Clinidium) segne R. Bell and J. Bell, and Clinidium (Clinidium) spatulanum R. Bell and J. Bell. Four revised keys are presented: Key to Species of Genus Arrowina; Key to Genera of Subtribe Clinidiina; Key to Species of Subgenus Rhyzodiastes (Rhyzostrix); and Key to Species of genus Clinidium (Clinidium). A discussion of the phylogeny of Clinidium (Clinidium) is given. The terminology for the antennal state of Omoglymmius americanus (Laporte), as used by Bell and Bell, is compared with that of Baker (2001).
