Indopadilla sabivia Maddison, sp. nov. Figs 117-120

Type material.

Holotype male (specimen d107, in UBCZ) from Malaysia: Sabah: Village of Kiabau. Central Sabah. 5.8315°N, 117.2245°E, 23 November 2000 K. Ober #00.437.

Etymology.

An arbitrary combination of letters, ungendered. Other names: In WPM’s lab notebooks the informal code for this species was “BVSAB”.

Diagnosis.

Palp similar to I. kahariana with a short sharp embolus with a TmA behind it, but the TmA is broader and more retrolaterally placed than in I. kahariana . RTA with sharp point, unlike the broad flat RTA of I. kahariana . These two species are sister groups on the molecular phylogeny (Fig. 1 ).

Description.

Male (based on holotype, specimen d107). Carapace length 2.8; abdomen length 3.8. Overall appearance similar to that of I. kahariana , paler coloured than many male Indopadilla , honey to medium brown. Carapace medium brown to honey coloured, darker on sides, with ocular area and larger portion of dorsal thorax quite pale. Clypeus narrow, exposing white arthrodial membrane. Chelicerae brown, with lateral ridge. Six retromarginal teeth, on long ridge. Palp pale except basal part of femur. Embolus short and sharp, with broad TmA behind (Fig. 117 ). Legs mostly honey coloured, first somewhat darker and with ventral fringe on patella through metatarsus. Abdomen in alcohol similar to that of female I. kahariana , with series of darker paired spots dorsally and elongated pale spots along the side.

Figures 1 - 3. Phylogeny. 1 Maximum Likelihood tree (best of 20 replicates) from combined data set of 1313 UCE loci, plus mitochondrial 16 SND 1 and COI regions, plus 28 S (dataset 4 in Methods). Baviines whose names are in bold, and all outgroups, have UCE data. Numbers are percentage of 500 bootstrap replicates showing the clade 2 Maximum Likelihood tree (best of 50 replicates) from concatenated data from 1313 UCE loci (dataset 1 in Methods). Numbers are percentage of 1000 bootstrap replicates showing the clade 3 Maximum Likelihood tree (best of 50 replicates) from concatenated data from mitochondrial data and 28 S (dataset 2 in Methods). Taxa in bold have data from the entire mitochondrial genome, or nearly so. Numbers are percentage of 1000 bootstrap replicates showing the clade for the full dataset ( 2), followed by the bootstrap percentage for the restricted mtDNA + 28 S dataset ( 3 in Methods). Spots at nodes show those clades that also appear in the ML tree in the restricted dataset. The branches to B. nessagyna and I. redynis are long, compacted visually by cutting and sliding part of the length over itself; the actual length therefore should be seen as longer by the length of the overlap.
