Gonopod eversible portion with one or two denticulate tubercles apically or subapically. Apex truncated. Abdominal segment I lacking a ventral chitinized plate. Brood pouch variable, may be elongate, pedunculate, conic or pyriform. Females may have corneous or papillose cephalic projections. Type by monotypy Branchinecta paludosa ( Müller, 1788 ) . Fig. 3. 50% Majority consensus tree from the 15 most parsimonious trees produced from a heuristic search of 51 morphological characters in PAUP. The proportion of 1,000 bootstrap replicates above 70% are shown. Comments : There are 52 species presently recognized (Rogers 2013; Rogers and Lorenz 2015 ) in seven species groups. Due to the lack diagnosis or definition in the work of Brtek and Mura (2000) , we have made no effort to associate our species groups with theirs; any attempt would be pure speculation. Subdivision : All the following species groups and incertae sedis taxa are part of Branchinecta . The shared characters between the ferox and the raptor groups, and the fact that these groups were consistently basal in our analyses, suggest that Branchinecta may have had a Eurasian origin, and via a stochastic dispersal event, invaded North America and rapidly differentiated across that continent in a manner similar to Streptocephalus ( Daniels et al. 2004 ) .
