Wide distribution and wide bodies: A new genus of Neopachylinae (Opiliones, Gonyleptidae) formed by false Discocyrtus.

Following the results of a maximum parsimony cladistic analysis of 30 terminal taxa against 117 morphologic characters (2978 scorings), the new genus Krateromaspis gen. nov. is described in Neopachylinae. This new genus accommodates three species from Argentina, Brazil and Paraguay, formerly included in Discocyrtus Holmberg, 1878: Krateromaspis antiqua (Soares 1946); Krateromaspis dilatata (Sørensen 1884) and Krateromaspis lata (Mello-Leitão, 1935). All species of Krateromaspis are redescribed, and Discocyrtus invalidus Piza, 1938 is newly considered a junior subjective synonym of Krateromaspis dilatata (Sørensen 1884), this species being quite widespread. The recent inclusion of Opisthoplatus Holmberg, 1878 in Neopachylinae (originally done without a phylogenetic analysis) is corroborated via this study. [ABSTRACT FROM AUTHOR]
