( Figs 13–15 ) Holotype . Male (IZCAS-Ar42687Fo). Late Cretaceous amber from Hukawng Valley . Syninclusion includes one beetle. Etymology. The species name is a popular Burmese girl’s name and means “prayer, offerings”; noun in apposition. Figure 13. Furcembolus inzaliae Jiang & Li , sp. nov. , holotype male (IZCAS-Ar42687). A. Left palp, retrolateral view; B. Right palp, dorsal view. Scale bars = 0.10 mm. Figure 14. Furcembolus inzaliae Jiang & Li , sp. nov. , holotype male (IZCAS-Ar42687). A–B. Habitus, lateral view; C. Ocular area, dorsal view; D. Tarsus and claw, lateral view. Scale bars: A–B= 0.50 mm; C =0.10 mm; D =0.05 mm. Diagnosis. This new species resembles F. crassitibia Wunderlich 2017 : (see Wunderlich, 2017: 129 , fig. 78) by the absence of an embolic apophysis but can be distinguished by the presence of a tibial apophysis and the shape of the bulb. The bulb of the new species bent three times at a right angle, while that of F. crassitibia folds two times at a right angle. Description. Male. Total length 2.59; carapace 0.88 long, 0.54 wide; opisthosoma 1.71 long, 0.91 wide. Left palp: 1.22 (0.56 + 0.18 + 0.48), left leg I: - (2.48 +0.39 + - + - + V ), leg II : - (1.36 + 0.37 + - + - + -), leg III : 3.59 (1.01 + 0.21 + 1.09 + 0.87 + 0.41), leg IV: - (1.39 + 0.28 + - + 1.34 + 0.52); right palp: - (- + 0.23 + -), right leg I–IV absent. Eye sizes and interdistances: ALE 0.07, PME 0.08, PLE 0.09, PME–PME 0.06. Habitus as in Figs 14A–B . Carapace ( Fig. 14A ) finely granulate, margin distinctly serrate, cephalic part of carapace noticeably highest posteriorly; eyes ( Fig. 14C ) ovoid, PLE> PME> ALE; labium triangular, distally obtuse; sternum granulate. Opisthosoma ( Figs 14A–B ): Abdomen oval with sclerotized lateral plates, smooth, modified by tiny pits, covered with thin setae; ventral scutum rugose; three tarsal claws ( Fig. 14D ), with a single pectinate row of teeth. Spinnerets not visible. Palp ( Figs 13A–B , 15 ). Femur more than 3 times longer than patella; patella short, ca. 0.1; tibia swollen, about two times wider than femur, with triangular apophysis in ventral view; cymbium small and compressed; bulb long, oval, proximally slightly swollen, bent, forming three right angles; embolic apophysis originates from middle of embolus, hookshaped.
