Diagnosis

Hind femur distinctly swollen medially, at most 3.3 × as long as wide ( Fig. 22F View Fig ); metasoma in lateral view strongly curved ( Fig. 21 View Fig ); lateral border of metasomal carapace distinctly curved ( Fig. 22J View Fig ); antenna basal third yellow and remainder brown ( Fig. 22E View Fig ); second submarginal cell strongly petiolate, about 1.0× as long as vein r ( Fig. 22G View Fig ); mesopleuron reticulate and with distinctly smooth area posteriorly ( Fig. 22I View Fig ); face and temple superficially rugulose ( Figs 22B, 22C View Fig ); head yellowish brown but around occipital carina darkened ( Fig. 22A View Fig ); metasoma dark brown except first tergite and second tergite medio-basally yellow ( Fig. 22J View Fig ).

Etymology

Named after the short and wide hind femur; ‘ brevis ’ is Latin for ‘wide’.

Remarks

Phanerotomella brevifemorata sp. nov. is similar to P. gladia Chen & Ji, 2003 in having a similar colouration of the body. However, P. brevifemorata can be easily distinguished from P. gladia by having vein m-cu antefurcal (postfurcal in the latter), the second submarginal cell strongly petiolate (sessile in the latter), the temple in dorsal view narrowing behind the eye (widening in the latter), the hind femur at most 3.3 × as long as wide (3.9 × in the latter), the basal half of the flagellum yellow and the apical half brown (entirely brown in the latter).

Phanerotomella brevifemorata sp. nov. is similar to P. longa Chen & Ji, 2003 because of the flagellum being basally yellowish and apically brown, the second submarginal cell distinctly petiolate, and the lateral border of the metasoma curved in dorsal view. However, P. brevifemorata sp. nov. can be distinguished from P. longa by having vein m-cu antefurcal (postfurcal in the latter), the temple in dorsal view narrowing behind the eye (widening in the latter), and the mesopleuron with a smooth area posteriorly (without a smooth area in the latter).
