Diagnosis.

Living female. Female covered with white wax powder.

Adult female. Labium three-segmented, longer than wide. Posterior pair of spiracles always larger than anterior spiracles. Circulus present or absent. Legs well developed, claw with or without denticle; tarsal digitules hair-like, not capitate; claw digitules knobbed, claw digitules broader than tarsal digitules. Only posterior ostioles developed; anterior ostioles absent. Anal lobes poorly developed. Anal ring oval, with one inner row of pores and one or two outer rows of pores plus with six setae. Minute discodial pores present of various sizes, scattered throughout.

Dorsum. Antennae 6-8 segmented. Eyes oval, each on a small basal cone. Cerarii present numbering 1-4, only on posterior abdominal segments. Dorsal body setae spinelike. Multilocular disc pores present or absent. Quinquelocular pores present, scattered all surface. Oral collar tubular present in transverse rows on body segments. Trilocular pores absent. Minute discodial pores present, from a few to scattered on the surface, variable in sizes.

Venter. Most ventral setae slender and hair-like, of various sizes. Oral collar tubular ducts of one or two sizes, each varying in length and width. Multilocular disc pores present on posterior abdominal segments, especially around vulva or absent. Quinquelocular pores present, scattered throughout. Trilocular pores, each 2.5-5.0 μm in diameter, only around atrium of both pairs of spiracles. Minute discodial pores present, of variable sizes, scattered through.

Comments. In this study, the concept of Kaydan (2011) and Foldi and Cox (1989) are accepted and Brevennia Goux sensu stricto is regarded as a valid genus and is considered to include: Brevennia cicatricosa (Danzig), Brevennia dasiphorae (Danzig), Brevennia filicta (De Lotto), Brevennia oryzae (Tang), Brevennia pulveraria (Newstead) and Brevennia rehi (Borchsenius). These species are characterized by: (i) lack of anterior ostioles; (ii) trilocular pores restricted to around each spiracular atrium on the venter and to the cerarii on the dorsum. For further discussion see Danzig and Gavrilov (2012; 2013), Kaydan (2011) and Foldi and Cox (1989).
