Wandella loloata View in CoL sp. nov.


Fig. 30 View Fig


This species is most similar to Wandella grayi Magalhaes, 2016 due to the tapering, long palpal bulb with erect paraembolic lamina in the male, and the female with columnar median receptacles attached to the rounded lateral receptacles via a stalk. Males can be diagnosed by the shorter, less curved embolus and the larger paraembolic lamina with an acute tip ( Fig. 30A–B View Fig ) (vs embolus longer and more curved, and smaller, curved paraembolic lamina in W. grayi ). Females can be diagnosed by the digitiform median receptacles, widest at the base, and by the stalk of the lateral receptacles connecting apically ( Fig. 30E–F View Fig ) (vs median receptacles with even width throughout, and stalks of the lateral receptacles connecting basally).


The name is a noun in apposition and is taken from the type locality.

Type material

Holotype PAPUA NEW GUINEA • ♂; Central Province , Loloata Island; 10 Nov. 1985; D.J. Court leg.; AM KS32718 .

Paratype PAPUA NEW GUINEA • 1 ♀; same collecting data as for holotype; AM KS32717 .


Male holotype (AM KS32718)

COLOURATION. Carapace mostly pale brownish-cream, lateral margins translucent; postocular area with a middorsal grey patterned triangular patch that narrows toward the foveal area around which it divides; lateral carapace with three grey pigment patches forming incomplete lateral bands; a pair of larger anterolateral grey patches flank the mostly cream-coloured clypeus. Chelicerae, labium, endites and sternum cream; abdomen pale creamy brown. Legs pale creamy brown, with dark grey partial ringlike patches restricted to proximal and distal femora and tibiae. Abdomen with well-defined brownish patterning on a cream ground. Frontal abdomen dark brown connecting dorsally to a broad middorsal brown patch with a paler central area; from this arise 5–6 pairs of brownish-grey dorsal chevrons reducing in size posteriorly; these are flanked below by a set of 4–5 smaller lateral chevrons on each side. Venter pale brown.

HABITUS. Anterior margin of carapace subrounded but anterolateral margins with concave (‘pinched’) curvature, clypeus unsclerotized and unpigmented. Sternum subrounded, bluntly pointed posteriorly, sigilla not seen.

MEASUREMENTS. Total length 2.43. Carapace length 1.02, width 0.79. Clypeus length 0.24. Eye diameters and interdistances: AME 0.07, PME 0.08, ALE 0.09, PLE 0.08; AME–AME 0.03, PME–PME 0.082. Sternum length 0.71, width 0.57. Palp: femur length 0.59, height 0.20; tibia length 0.33, height 0.14. Legs 1423. Leg I: 5.99 (1.50, 0.40, 1.78, 1.41, 0.90). II: 4.26 (1.07, 0.31, 1.31, 1.02, 0.55). III: 3.87 (1.02, 0.33, 1.02, 1.05, 0.45). IV: 4.99 (1.31, 0.32, 1.67, 1.12, 0.57). Abdomen length 1.51, width 0.92.


PALP. Cymbium horseshoe shaped; tegulum with a shallow prolateral excavation; presence or absence of microspine surface structures could not be verified; sperm duct N-shaped with a single coil; crest-like paraembolic process present; embolus slender, slightly curved.

Female paratype (AM KS32717)

COLOURATION. As in male.

HABITUS. Sternal sigilla not seen.

MEASUREMENTS. Total length 3.57. Carapace length 1.57, width 1.31. Clypeus length 0.31. Eye diameters and interdistances: AME 0.06, PME 0.09, ALE 0.20, PLE 0.11; AME–AME 0.06, PME–PME 0.15. Sternum length 1.06, width 0.95. Palp: femur length 0.86 width 0.36; tibia length 0.50, width 0.26. Legs I: 6.9 (1.79, 0.43, 1.90, 1.64, 1.14). II: 4.44 (0.83, 0.37, 1.19, 1.05, 1.00). III: 3.88 (0.95, 0.40, 0.95, 0.75, 0.83). IV: 5.9 (1.59, 0.50, 1.52, 1.31, 0.98). Abdomen length 2.14, width 1.48.

LEG MACROSETAE. Absent. Calamistrum with three rows of setae.


ENDOGYNE. Lateral receptacle large and rounded with scattered pores and a curved stalk-like basal attachment; median receptacles smaller with many pores clustered apically.
