Diagnosis
Antenna with white band on 10 th –12 th segments ( Fig. 4K View Fig ); mandible basal half blackish and apical half yellowish and with reddish teeth ( Fig. 4D View Fig ); hind femur slender, 5.6× as long as wide ( Fig. 4F View Fig ); body length about 5.3 mm ( Fig. 3 View Fig ); body black ( Fig. 3 View Fig ); hind femur black and hind tibia black except basally white ( Fig. 4F View Fig ).
Etymology
Named after white antennal band; ‘ annulatus ’ is Latin for ‘ringed’.

Remarks
Phanerotomella annulata sp. nov. is similar to P. taiwanensis in having a similar colouration of the body and hind femur. However, Phanerotomella annulata can be easily distinguished from P. taiwanensis by having an antenna with a white band on the 10 th –12 th segments (antenna with white band on 3 rd- 4 th segments in the latter), the hind femur 5.6× as long as wide (4.7 × in the latter), the more robust mandible and an inner tooth 0.7 × as long as apical tooth (slender and 0.5 × in the latter), and the mandible basal half black and apical half yellow (mandible yellow in the latter).
