scientific name

Priscaleclercera thanae Jiang & Li
status

sp. nov.

Priscaleclercera thanae Jiang & Li , sp. nov. ( Figs 31–33 View Figure 31 View Figure 32 View Figure 33 )

Holotype. Male (IZCAS-Ar42694Fo). Late Cretaceous amber from Hukawng Valley. Syninclusion includes one dipteran . Paratype male (IZCAS-Ar42695Fo). Late Cretaceous amber from Hukawng Valley. No biotic syninclusions .

Etymology. The species name is a popular Burmese girl’s name and means “a million”; noun in apposition.

Diagnosis. This species resembles P. paucispinae (see Wunderlich, 2017: 151, figs 119–121, photo 75) by the presence of forks on the sclerites. The new species can be distinguished from the latter by the sclerite 2 without a forked tip in retrolateral view ( Fig. 31A View Figure 31 ).

Description. Male. Total length 2.38; Carapace 0.72 long; Opisthosoma 1.66 long. Left palp: - (0.49+ 0.18 + -), left leg I: - (3.28 + 0.27 + 3.48 + - + -), leg II-IV absent, right leg I absent, leg II: 9.67 (2.97 + 0.13 + 3.03 + 2.84 + 0.70), leg III: 4.81 (1.56 + 0.16 +1.22 + 1.31 + 0.56), leg IV: 9.64 (3.21 + 0.31 + 2.56 + 2.78 + 0.78). Eye sizes and interdistances: ALE 0.04, PLE 0.03, PME 0.05, PLE–PME 0.04. Habitus as in Figs 32A–D View Figure 32 . Carapace round ( Fig. 32B View Figure 32 ), brown, six eyes ( Fig. 32C View Figure 32 ) almost ovoid, PME> ALE> PLE; labium not visible. Abdomen ( Figs 32A–B View Figure 32 ) light yellow, elongate. Anterior lateral spinnerets ( Fig. 32D View Figure 32 ) cylindrical, with three segments.

Palp ( Figs 31A–B, D View Figure 31 , 33 View Figure 33 ). Femur with at least five short macrosetae ventrally; cymbium longer than wide, with dense brown setae; cymbium with three macrosetae: one retrolateral long and curved with a hook, and two preapical, short, subconical. Bulb longer than wide, with oval basal portion, and three sclerites apically. Sclerite 1 forked, appressed to sclerite 2. Sclerite 2 elongate, serrated apically. Sclerite 3 disc-shaped with two horn-shaped apophyses.

Male (paratype, IZCAS-Ar42695Fo, Fig. 31C View Figure 31 ). Same as holotype.
