Diagnosis.

The species is closely related to Phintella accentifera , P. aequipeiformis , P. argentea , and P. suavis in palpal morphology. However, it is distinguishable by the transverse metallic bands on the abdomen in both sexes (Figs 34 A–F), comparably smaller and broader ALT, dorsally curved RTA (Figs 35DE, 36A, B) in males and oval spermathecae and moderately recurved SC border in females (Figs 29H, 36C, D).

Description.

Male. Small spiders (less than 5.0 mm). In life, prosoma oval and black with transverse blue metallic band on the middle of the eye field (Figs 34A, B, E, F). Surroundings of eyes black-grey with sparse grey-brown setae ( Prószyński 1992; Roy et al. 2016; Żabka 1985). Clypeus covered with blackish grey gleaming setae. Chelicerae glossy black with blackish brown fangs. Transverse large diamond-shaped metallic blue blotch behind eye field (Fig. 34A, E, F). Rounded sternum, brownish grey in ethanol preserved specimens (Fig. 35B). Two silvery belts on each lateral sides of prosoma (Fig. 34A, E). Posterior margin of prosoma steep, slightly truncated. Glossy brownish black legs except greyish yellow metatarsus and leg I somewhat robust.

Abdomen slightly shorter and narrower than prosoma, tapering posteriorly. Dorsum decorated with transverse blue and black metallic lustrous banding pattern, single transverse golden yellow at the posterior region (Figs 34A, E, F). Ventrum blackish grey with devoid of markings (Fig. 35B). Spinnerets pale yellow.

Brownish black palp. Short cymbium narrows at distal region. Embolus short, somewhat stout immovable, on rather triangular apical portion of tegulum, extending beyond the level of the distal end of tegulum (Figs 35 D–E, 36 A–B). Large triangular flap on side of embolus (lamellar process) conspicuous (Figs 35D, 36A). Bulbus elongated. Sperm duct comparably broader at the distal end of tegulum, narrower at the apical portion of tegulum. Small hump at retrolateral portion of bulbus. Proximal lobe of tegulum with well-developed posterior lobe at the prolateral side. Palpal tibia short, two, unequal sized lateral apophysis (Figs 35D, E, 36A, B), a small tooth on the posterior (dorsal) surface of tibia ( Peng et al. 1993; Prószyński 1992; Żabka 1985).

Female. As in male except for greyish yellow legs and distal end of femur IV and tibia IV with black patches (Figs 34C, D). Epigynum strongly sclerotised with well-developed scapum, extending beyond the line of epigastric furrow at the posterior margin (Figs 29G, H, 36C, D). Copulatory openings clearly visible. Large and oval spermathecae with strongly sclerotised thick wall (Figs 29H, 36C, D). Copulatory canals externally in the shape of letter “V” ( Żabka 1985). FD lanceolate, opening into the anterior wall of receptacles (Figs 29H, 36D).
