Priscaleclercera kyawae Jiang & Li , sp. nov. ( Figs 28–30 )

Holotype. Male (IZCAS-Ar42693Fo). Late Cretaceous amber from Hukawng Valley. No biotic syninclusions.

Etymology. The species name is a girl’s name from Myanmar and means “famous, fame”; noun in apposition.

Diagnosis. This species resembles P. furcata (see Wunderlich, 2020: 101, figs 106–107, photos 18–19) by the shape of sclerite 3 on the bulb but can be distinguished by the pointed apophysis of sclerite 1 ( Figs 28A–D ) and the forked, membranous apex of sclerite 2 ( Figs 28A–D ).

Description. Male. Total length -; carapace not visible; opisthosoma 1.01 long, 0.52 wide. Left palp: - (- + - + 0.28), left leg I: - (1.78 + 0.23 + 2.02 + 1.08 + -), leg II, III absent, leg IV: - (1.90 + 0.21 + 2.10 + - + -); right palp: 0.80 (0.37 + 0.14 + 0.29), right leg I absent, leg II: 4.85 (1.52 + 0.10 + 1.66 + 1.36 + 0.21), leg III: - (1.03 + 0.22 + 0.91 + 0.94 + -), leg IV: - (1.47 + 0.17 + 1.64 + - + -). Eyes not visible. Habitus as in Figs 29A–B . Opisthosoma ( Figs 29A–B ): Abdomen elongate, yellow.

Palp ( Figs 28A–D , 30 ). Femur with at least five short macrosetae ventrally; cymbium longer than wide with a retrolateral macroseta which long and curved with a hook. Bulb longer than wide and with three sclerites apically. Sclerite 1 elongate, boot-shaped in retrolateral view, with an apophysis medially. Sclerite 2 with a forked, membranous apex. Sclerite 3 strongly sclerotized with a pointed apophysis medially.
