Pogonioefferia frewingi (Wilcox) 

Efferia frewingi Wilcox, 1966b: 169  .

Recognition characters: Grayish black species; length 14–21 mm; mystax with black bristles intermixed with white setae; bristles and setae of mesonotum mostly black, postpronotal setae white anteriorly, black posteriorly, supraalar setae white; meral bristles white; scutellar setae mixed white and black, marginal bristles black in males; abdominal segments 2–5 black setae dorsocentrally, segments 6 and 7 silvery white pollinose; legs black except fore- and mid-tibiae with basal anterior half brown. Can be differentiated from both P. helenae  and P. bicaudata  by the position of the discal crossvein which is opposite the forking of the third longitudinal vein in P. frewingi  as well as by the structure of the male basistyle in which the arms are of equal length in P. frewingi  .
