Holotype. Male (IZCAS-Ar42684Fo). Late Cretaceous amber from Hukawng Valley. No biotic syninclusions.
Etymology. The species name is a popular Burmese boy’s name and means “sky”; noun in apposition.
Diagnosis. Zamilia arkari Jiang & Li , sp. nov. resembles Z. quattuormammillae Wunderlich, 2015 (see Wunderlich, 2015: 296, figs 300–309, photo 147) by the trapeziform median apophysis. Z. quattuormammillae has a tegular apophysis in addition to the median apophysis, while the new species does not have.
Description. Male. Total length 3.80; carapace 1.55 long, 1.44 wide; opisthosoma 2.25 long, 1.25 wide. Left palp: - (0.66 + 0.32 + -), left leg I: 7.08 (2.09 + 0.62 + 1.73 + 1.87 + 0.77), leg II: 7.84 (2.82 + 0.71 + 1.52 + 1.90 + 0.89), leg III: - (2.02 + 0.69 + - + - + -), leg IV: 6.75 (1.86 + 0.52 + 1.34 + 2.09 + 0.94); right palp: - (0.78 + - + -), right leg I: 6.80 (1.88 + 0.59 + 1.62 + 1.81 + 0.90), leg II: 7.08 (1.93 + 0.72 + 1.71 + 1.89 +0.83), leg III: 5.71 (1.75 + 0.66 + 1.52 + 1.03 + 0.75), leg IV: - (1.93 + 0.48 + 1.47 + 1.79 + -). Eye sizes and interdistances: ALE 0.08, AME 0.08, PLE 0.09, PME 0.04; AME– AME 0.04, AME–ALE 0.02, PME–PLE 0.06, PME–PME 0.19. Habitus as in Figs 5A–B View Figure 5 . Carapace almost round, longer than wide, yellow. Sternum oval, yellow, with dense brown setae. Metatarsi with 2 distal spines. Opisthosoma elongate. Anterior lateral spinnerets ( Fig. 5D View Figure 5 ) short, posterior spinnerets with terminal segment long, ca. 0.63, basal segment short, ca. 0.20; anal tubercle fringed with long setae.
