Caroline Sayuri Fukushima, Rogério Bertani, Pedro Ismael da Silva Júnior
The genus Cyriocosmus Simon, 1903 is revised based on most types and additional material from Argentina, Brazil, Colombia, Tobago Island and Venezuela. Two species are newly described from Brazil: Cyriocosmus nogueira-netoi and Cyriocosmus fernandoi. The species Cyriocosmus fascia-tus (Mello-Leitão, 1930), formerly synonymized with Cyriocosmus elegans, is revalidated. Metrio-pelma nigriventris (Mello-Leitão, 1939) and Cyriocosmus butantan Pérez-Miles, 1998 are transferred to Hapalopus Ausserer, 1875, proposing Hapalopus nigriventris (Mello-Leitão, 1939) new combination and Hapalopus butantan (Pérez-Miles, 1998) new combination. The female of Hapalopus butantan is described for the first time. All 11 species of Cyriocosmus are diagnosedand keyed. A cladistic analysis with 28 characters and 19 taxa was carried out. Searches using three phylogenetic packages found a single, totally resolved tree with the same topology.
