Diagnosis

Body coloration of both males and females of Phintella candramawa Dhiya’ulhaq sp. nov. is identical to that of Phintella liui Wang, Mi & Peng, 2023 but is easily distinguished by the genitalia. Males have RTA with a long dorsal keel (Fig. 25C, E vs absent in P. liui [Wang et al. 2023: fig. 20b]); much longer embolus, approximately one fifth length of tegulum (Fig. 25B, D vs embolus 1/25 length of tegulum in P. liui [Wang et al. 2023: fig. 20a]); and trapezoid lamellar process, twice as long as wide (vs elongated, four times as long as wide). Females lack basal protrusion and atrial ridge present in P. liui (Fig. 28A; Wang et al. 2023: fig. 21a). In addition, female genitalia are very similar to those of Phintella accentifera (Simon, 1901), Phintella handersoni Sen, Sudhin & Caleb, 2024 and Phintella nilgirica Prószyński, 1992 but can be distinguished by vertical, slit-shaped copulatory openings (vs diagonal, oval-shaped in P. accentifera [Asima et al. 2024: figs 54, 61] and P. nilgirica [Prószyński 1992a: figs 62–63]; circular in P. handersoni [Sudhin et al. 2024b: fig. 4g]).

Etymology

The specific epithet is taken from the Indonesian word ‘ candramawa ’ which refers to the black-andwhite pattern of certain cats, alluding to the male coloration of Phintella candramawa sp. nov. Noun in apposition.
