Mortoniella collegarum (Rueda Martín and Gibon) : Blahnik and Holzenthal 2011: 51 [redescription, reillustration, distribution, member of ormina group].

This species was described from Bolivia by Rueda Martín and Gibon and subsequently recorded from Argentina and Chile by Blahnik and Holzenthal, who also redescribed and reillustrated the species. The reader is referred to that paper for the redescription and discussion of the variability encountered. The species is readily identified by the emarginate apicolateral margin of tergum X and by the form of the dorsal phallic spine, which has its apex sharply upturned and mesally cleft. The type and the reillustration by Blahnik and Holzenthal (2011), based on a specimen from Chile, are characterized by having the margin of the apex of the dorsal phallic spine serrate and covered with small spines. The latter character was absent from some of the specimens examined in a series from Argentina, and is also absent in the specimen from Bolivia that is reillustrated here. Although other examined specimens from the series from Bolivia were consistent in the character variation illustrated, the difference from the type is relatively minor and we are interpreting this as intraspecific variation.
