sp. nov. |
Bicornoculus aungi Jiang & Li , sp. nov. ( Figs 37–39 View Figure 37 View Figure 38 View Figure 39 )
Holotype. Male (IZCAS-Ar42697Fo). Late Cretaceous amber from Hukawng Valley. Syninclusion includes one hemipteran.
Etymology. The species name is a popular Burmese boy’s name and means “success”; noun in apposition.
Diagnosis. This species resembles B. levis (see Wunderlich, 2015: 165, figs 117–121, photo 43–44) by the spindleshaped bulb but can be distinguished by the wave-shaped embolus ( Figs 37A–D View Figure 37 , 39 View Figure 39 ). The embolus of the new species is longer than B. levis .
Description. Male. Total length 2.13; carapace 0.90 long, 0.55 wide; opisthosoma 1.23 long, 0.74 wide. Left palp: 0.43 (0.23 + 0.08 + 0.12), left leg I: - (0.79 + 0.22 + - + - + 0.30), leg II: 2.10 (0.71 + 0.23 + 0.51 + 0.36 + 0.29), leg III: - (0.58 + - + - + 0.32 + 0.24), leg IV: - (0.70 + - + - + 0.39 + 0.20); right palp: 0.40 (0.20 + 0.09 + 0.11), right leg I: - (0.81 + 0.22 + - + - + 0.24), leg II: - (0.61 + 0.18 + - + - + 0.20), leg III: - (0.54 + - + - + - + 0.20), leg IV: - (0.64 + - + - + 0.43 + 0.23). Eye sizes: ALE 0.05, PLE 0.06, PME 0.04, eyes interdistances not visible. Habitus as in Figs 38A–B View Figure 38 . Carapace ( Figs 38A–B View Figure 38 ) reticulated, brown; clypeus brown; six eyes ( Figs 38C–D View Figure 38 ) almost ovoid, PME <ALE <PLE; sternum reticulated, rugose. Opisthosoma ( Figs 38A–B View Figure 38 ): Scutum long, oval, covered with long setae, reticulated, center granulated; ventral scutum reticulated, margin rugose.
Palp ( Figs 37A–D View Figure 37 , 39 View Figure 39 ). Bulb long with two apophyses distally, apophyses curved, with serrated margin; embolus sclerotized, slender, bent twice.
