Figs 56–57
Diagnosis
The species may be distinguished by a characteristic striped and silvery shinning abdomen (Fig. 56A, D). The palpal organ is thin with a thick embolus that is broader than in most other species in the genus. The presence of accessory glands connected to the copulatory ducts is characteristic of the female genitalia. Similar glands can only be found in Phintella lunda Wesołowska, 2010 and Phintella incerta Wesołowska & Russel-Smith, 2000, but these two species have longer copulatory ducts than Phintella bella sp. nov.
Etymology
The name of this species is Latin word, meaning ‘beautiful’, and refers to the silvery shining abdomen characteristic for both sexes.
