### Implicit attributes

Unless indicated otherwise, the following attributes are implicit throughout the descriptions, except where the characters concerned are inapplicable.

Head. Frons without brown markings except ocellar tubercle. Occiput without brown marks. Ocellar seta weak, small or absent. Gena without brown spot. Facial carina in profile concave or flat on dorsal 2/3. Face with ventral part gradually tapered laterally; without brown markings. Face without whitish markings. Antenna not extended to ventral margin of face. Arista of male without preapical expansion. Palpus in lateral view evenly setulose.

Thorax. Postpronotal, presutural supra-alar, dorsocentral, intra-alar and scutellar setae well developed, subequal to or longer than scutellum length. Acrostichal seta well developed. Basal scutellar seta strong, longer than scutellum. Scutum pale sublateral postsutural vitta extended posteriorly to intra-alar seta.

Wings. Cell bm entirely hyaline or infuscated only along subapical fold. S-band distal section without marginal hyaline band or spots in cell r2+3 or near apices of R2+3 or R4+5. Area surrounding apex of lobe of cell bcu with microtrichia similar in density to area anterdistal to it along vein Cu1. Costa in male with setulae on anterior margin between crossvein h and apex of vein R1 similar to other setulae. Crossvein dm-cu orientation with anterior end more distal than posterior end.

Abdomen. Abdomen ovate or parallel-sided, syntergite 1+2 gradually broadening or parallel-sided. Abdominal tergite without brown markings. Glans without spinules. Eversible membrane, subbasally on ventral side without cluster of hairs.

Miscellaneous. Data recording adequate.

We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
