Description
Female. Length, 7.0 mm. Antenna black; scape and pedicel white. Head black with labrum and palpi white. Thorax black; tegula, pronotum, and postspiracular sclerite (except anterior margin) white; mesoscutellum white at center, black at sides, scutellar appendage and metanotum pale orange. Abdomen with basal plates black; tergites 4–5 with broad anterior halves half or more black; posterior portion black, 6-9 with very narrow posterior portion white; sheath black. Legs white, only apical tarsomeres black. Wings hyaline, veins and stigma black.
Head and body shiny, with fine, minute punctures; covered with fine, white pubescence. Antennal length 2.3× head width; 3rd and 4th antennomeres subequal in length. Malar space linear. Distance between eye and hind ocellus subqual to slightly shorter than distance between hind ocelli. Postocellar area 2.4× broader than long. Lower interocular distance slightly less than eye height. Forewing with 4 cubital cells; intercostal crossvein present and interstitial with M. Pulvilli small; only evident on tarsomeres 3 and 4. Hind basitarsomere subequal to slightly shorter than length of remaining tarsomeres combined; inner hind tibial spur about 0.4× length of basitarsomere and subequal to width of hind tibia at apex. Tarsal claws with long inner tooth, about equal in length and width of outer tooth. Sheath broadened at apex, with distinct rounded scopae (similar to Benson 1958[1], fig. 414). Lancet (Fig. 21) with 14 serrulae; each with 6–8 very fine subbasal teeth, large spurette dorsal to anterior edge of serrulae 3 to apex, spurette about as large as serrula; basal annuli curved, each with broad band of long stout spines.
Male. Length, 6.5 mm. Similar to female except head with clypeus and spot on lower inner orbit white; pronotum black with posterior edge narrowly white; and mesoscutellum black. Malar space about half diameter of front ocellus. Lower interocular distance about 1.1× eye height. Forewing with intercostal crossvein present and basal to vein M; with 3 cubital cells. Genitalia in Figs 32, 33; penis valve slender, with a short small valvispina directed vertically near center of valve.

Etymology
The species name is an arbitrary combination of letters and is to be treated as a noun.
Discussion
I have not seen other species of Pristiphora with large spurettes above the serrulae plus the strong, stout spines on the annuli (Fig. 21). The only other Pristiphora species illustrated that apparently has such spurettes on the lancet is Pristiphora lineogenata Wei (in Wei and Nie 2002[2]: fig. 67) from Guizhou Province, China, but Wei illustrated only two serrulae and he compares his species with Pristiphora borneensis, with which Pristiphora ettera has no similarities (see Wong 1977[3]: fig. 15). Pristiphora etteri also has the scape, pedicel, mesoscutellum, posterior margins of the tergites, and the sternites white, whereas these are black in Pristiphora lineogenata. The male penis valve (Fig. 33) is similar to that of Pristiphora sauteri, illustrated by Wong (1977[3]: fig. 8).
