UCE and Sanger sequenced data for phylogenetic analysis of jumping spiders (Baviini and Nungia, Salticidae)

The systematics and taxonomy of the tropical Asian jumping spiders of the
tribe Baviini is reviewed, with a molecular phylogenetic study (UCE
sequence capture, traditional Sanger sequencing) guiding a
reclassification of the group's genera. The well-studied members of
the group are placed into six genera: Bavia Simon, 1877, Indopadilla Caleb
& Sankaran, 2019, Padillothorax Simon, 1901, Piranthus Thorell,
1895, Stagetillus Simon, 1885, and one new genus, Maripanthus Maddison.
The identity of Padillothorax is clarified, and Bavirecta Kanesharatnam
& Benjamin, 2018 synonymized with it. Hyctiota Strand, 1911 is
synonymized with Stagetillus. The molecular phylogeny divides the baviines
into three clades, the Piranthus clade with a long embolus (Piranthus,
Maripanthus), the genus Padillothorax with a flat body and short embolus,
and the Bavia clade with a higher body and (usually) short embolus
(remaining genera). In general, morphological synapomorphies support or
extend the molecularly-delimited groups. Eighteen new species are
described (all with taxonomic authority W. Maddison): Bavia nessagyna,
Indopadilla bamilin, I. kodagura, I. nesinor, I. redunca, I. redynis, I.
sabivia, I. vimedaba, Maripanthus draconis (type species of Maripanthus),
M. jubatus, M. reinholdae, Padillothorax badut, P. mulu, Piranthus api, P.
bakau, P. kohi, P. mandai, and Stagetillus irri. The distinctions between
baviines and the astioid Nungia Żabka, 1985 are reviewed, leading to four
species being moved into Nungia from Bavia and other genera. Fifteen new
combinations are established, and one combination is restored. Five of
these new or restored combinations correct previous errors of placing
species in genera that have superficially similar palps but extremely
different body forms, in fact belonging in distantly related tribes —
emphasizing that the general shape of male palps should be used with
caution in determining relationships. A little-studied genus,
Padillothorus Prószyński, 2018, is tentatively assigned to the Baviini.
Ligdus Thorell, 1895 is assigned to the Ballini.
