VARIATION. Length of fore wing of female 2.0– 2.1 mm. Male Unknown. Host Unknown. Distribution China (Guizhou, Zhejiang). 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).
