Type specimen.

Holotype female, Mount Canala (21°31'S, 165°58'E, New Cale-donia), F. Sarasin and J. Roux (NHMB 979a). Photographs examined.

Other material examined.

1 male, 7 females (in 8 records)(see Suppl. material 1).

Diagnosis.

Males of S. canalae comb nov. shares with S. tartara sp. nov. two patellar setae on the pedipalp (Fig. 12C, D vs. Fig. 22C, D). However, S. canalae comb nov. is distinguished by prominent, heavily sclerotised conductor of S. tartara sp. nov. which is short and inconspicuous in S. canalae comb. nov. Female genitalia are most similar to those of S. brisbanae comb. nov., but differ from those and other Salsa gen. nov. species by the epigyne scape, that is longer than the epigyne plate and exceeds its posterior margin (Fig. 13C, D).

Redescription.

Male (based on WAM T75922) Total length 5.5. Carapace 2.9 long, 2.5 wide, pear-shaped and pale brown, covered with short white setae (Fig. 12A). Eye diameter AME 0.20, ALE 0.18, PME 0.13, PLE 0.11; row of eyes: AME 0.54, PME 0.47, PLE 1.22. Chelicerae yellowish brown; with four promarginal teeth (second basal largest) and three retromarginal teeth (basal largest). Legs yellowish brown mottled in pale brown, bearing thick setae on patella, tibia and metatarsus (Fig. 12A, B). Leg formula I> II> IV> III; length of segments (femur + patella + tibia + metatarsus + tarsus = total length): I - 2.8 + 1.2 + 2.2 + 1.7 + 0.9 = 8.8, II - 2.2 + 1.0 + 1.6 + 1.6 + 0.8 = 7.2, III - 1.4 + 0.6 + 0.8 + 0.8 + 0.5 = 4.1, IV - 2.1 + 0.9 + 1.5 + 1.5 + 0.7 = 6.7. Labium 0.31 long, 0.47, and endites yellowish brown, paler anteriorly (Fig. 12B). Sternum 1.3 long, 0.8 wide, yellowish brown mottled dark and bearing dark brown contour (Fig. 12B). Abdomen 2.5 long, 1.8 wide, with pointed conical posterior portion after spinnerets, dorsum, sides, and venter beige mottled in grey (Fig. 12A, B). Pedipalp (Fig. 12C, D) length of segments (femur + patella + tibia + cymbium = total length): 0.5 + 0.2 + 0.15 + 0.9 = 1.75; patella with two setae; paracymbium reduced and straight; median apophysis elongated, with a thick basal process, a notched apical section on an acute and apically curved rounded tip; conductor lobe small; terminal apophysis subrectangular, apically projected and inflated, bearing a finger-like lobe from its basis; conductor flat with sclerotised borders; embolus short and strong, very sclerotised.

Female (based on WAM T75921): Total length 8.3. Carapace 3.5 long, 3.1 wide; dark brown and bearing long white setae throughout (Fig. 13A). Eye diameter AME 0.20, ALE 0.18, PME 0.14, PLE 0.13; row of eyes: AME 0.52, PME 0.45, PLE 1.88. Chelicerae dark brown, four promarginal teeth (apical and basal largest), and three retromarginal (basal largest). Legs orange-brown, slightly darker on femur and joints (Fig. 13A, B). Pedipalp length of segments (femur + patella + tibia + tarsus = total length): 1.0 + 0.5 + 0.7 +1.1 = 3.3. Leg formula I> II> IV> III; length of segments (femur + patella + tibia + metatarsus + tarsus = total length): I - 3.2 + 1.4 + 2.7 + 2.4 + 1.1 = 10.8, II - 2.8 + 1.5 + 2.2 + 2.2 + 0.9 = 9.6, III - 1.9 + 0.9 + 1.0 + 1.0 + 0.7 = 5.5, IV - 2.8 + 1.2 + 2.0 + 2.1 + 0.9 = 9.0. Labium 0.54 long, 0.86 wide and endites dark brown, beige on anterior border (Fig. 13B). Sternum 1.5 long, 1.5 wide and brown (Fig. 13B). Abdomen 5.5 long, 5.2 wide; dorsum with beige background brindled in olive-grey (Fig. 13A); sides olive-grey (Fig. 13B); venter olive-grey with two thick rounded white patches (Fig. 13B). Epigyne subquadrate with broadly rounded antero-lateral borders and wide atrium and basis (Fig. 13C, D); scape almost twice the length of epigyne base, from a slightly wide base gradually narrowing a thin section (Fig. 13C-E); central division goblet-like, very wide anteriorly, ca. as wide as the epigyne base, and tapering basally (Fig. 13F); spermathecae oval and apart by more than its diameter (Fig. 5C).

Variation.

Only one male was available for measurements (see above); female total lengths 5.8 and 6.4 (n = 2). All our specimens were of very similar colouration, but Berland (1932) reported numerous females with considerable colour variations, specifically of the abdomen, without providing any further detail.

Life history and habitat preferences.

The mature male described here was found in April, mature females examined between February and June; however, specimen numbers are too small to confidently interpret the phenology of the species. There was no information on habitat with any specimen labels.

Distribution.

Distributed throughout New Caledonia (Fig. 14), including Nouméa (cited in Berland 1932).
