Holotype. Male (IZCAS-Ar42688Fo). Late Cretaceous amber from Hukawng Valley. Syninclusion includes one mite. Paratype male (IZCAS-Ar42689Fo). Late Cretaceous amber from Hukawng Valley. No biotic syninclusions.

Etymology. The species name is a popular Burmese boy’s name and means “everlasting or immortal”; noun in apposition.

Diagnosis. The new species can be distinguished from all other Priscaleclercera species by the shape of the palpal sclerites: sclerite 1 with 3 apices; sclerite 2 with two needle-shaped, strongly sclerotized structures distally; sclerite 3 with sclerotized structure with membranous margin.

Description. Male (holotype): carapace 0.75 long, 0.52 wide; opisthosoma absent. Left palp: 1.26 (0.62 + 0.13 + 0.51), legs absent. Eye sizes and interdistances: ALE 0.03, PLE 0.03, PME 0.04, PLE–PME 0.04. Habitus as in Figs 17A–B. Carapace oval (Fig. 17A), brown; six eyes (Fig. 17A) almost ovoid, PME> ALE = PLE; labium not visible.

Palp (Figs 16A–B, 18). At least five short macrosetae ventrally on femur; cymbium 0.45 long, 0.12 wide, with dense brown setae; cymbium with three macrosetae: a long, curved retrolateral one with a hook, and two preapical, short, subconical ones. The bulb bears three sclerites apically. Sclerite 1 and 2 slender, sclerotized. Sclerite 3 forked, with triangular apophysis.
