UROSTYLIDIDAE Dallas , sensu stricto Historical: The systematic position of this family has been ambiguous over time, as was stressed by Schuh and Slater (1995). Singh-Pruthi (1925) related it

to the Acanthosomatidae . Yang (1938a,b, 1939) and Pendergrast (1957) related it to the Pyrrhocoridae , and Miyamoto (1961) to the Pentatomidae . Kumar (1971) believed that the group represented an early divergence from the other pentatomomorphans, possibly together with the Pyrrhocoridae , with which they share uniquely the fused 2nd valvifers that form an M- or W-shaped sclerite. As Gapud (1991) did not provide an illustration of what he considered as separate 2nd valvifers, we conclude that he erroneously interpreted the 2nd valvifers in the species of Urostylididae that he studied. Berger et al. (2001) proposed the emended spelling Urostylididae , in order to remove the homonymy between the heteropteran family name and Urostylidae Bütschli (Ciliophora, Hypotrichia).

Analytical result: The treatment of the Urostylididae as the basal grouping within the Pentatomoidea by Gapud (1991) is a position supported by our morphological analyses ( Figs 42–44 View Fig View Fig View Fig ) and combined analyses under an unweighted equal costs regime ( Figs 51 View Figs 49–52. 49 and 53 View Fig ). Under unequal costs, Urochela is dissociated from Urostylus and moved up to a more central position within the pentatomoid cladogram. Characters supporting the treatment of the Urostylididae sensu strico as the sister group of all remaining Pentatomoidea are listed below in the Conclusions. The monophyly of the Urostylididae sensu strico is

recognized in our analysis by the presence of a stridulitrum on A 1 in the hind wing (221) and the presence of bristles on the claws (311). Additionally, gonocoxites 9 (in females) form an Mor W-shaped

sclerite (465; Fig. 28 View Figs 25–34. 25 ), which we suggest argues for its treatment at the family level.
