Proposal and phylogenetic relationships of Lapsamita, a new genus of lapsiines, and description of a new species (araneae, salticidae).

Ruiz GR - PLoS ONE (2013)

Bottom Line: The presence of palpal claws in females, long ventral spines on front tibiae and metatarsi and long retrolateral tibial apophyses in male palps suggested that the species was closely related to or even nested within Soesiladeepakius Makhan, 2007.The analysis showed L. maddisoni as the sister group of Soesiladeepakius, supporting the proposal of the new genus.Character evolution is discussed and compared to a previous study on the group.

ABSTRACT
Lapsamita maddisoni gen. et sp. nov. is described from Bahia, Brazil. The presence of palpal claws in females, long ventral spines on front tibiae and metatarsi and long retrolateral tibial apophyses in male palps suggested that the species was closely related to or even nested within Soesiladeepakius Makhan, 2007. To evaluate its phylogenetic position, a cladistic analysis was carried out using a data matrix comprising 24 morphological characters, scored for 13 taxa. The analysis showed L. maddisoni as the sister group of Soesiladeepakius, supporting the proposal of the new genus. Character evolution is discussed and compared to a previous study on the group.

Chosen best tree of phylogenetic reconstruction of the lapsiines using morphological data.White and black circles on branches represent, respectively, homoplasious and non-homoplasious transformations. Numbers under circles indicate characters; for detailed character description and discussion, including question marks under numbers, see previous study [6].

Numbers under circles indicate characters; for detailed character description and discussion, including question marks under numbers, see previous study [6].

Mentions: In the other shortest tree, Galianora showed up as the sister group of Lapsamita + Soesiladeepakius. Although we still do not have molecular data available for Lapsamita maddisoni, the closer relationship between Galianora and Soesiladeepakius was found in analyses using DNA sequences [6], and the topology (Galianora (Lapsamita + Soesiladeepakius)) is expected to be corroborated in forthcoming molecular studies. This topology is chosen in this paper to discuss character evolution (Fig. 3).
