description: Subgenus Painjunirmus Ansari, 1947
Brueelia Kéler, 1936: 257 (in partim).
Painjunirmus Ansari, 1947: 285.
Type species
Painjunirmus pengya Ansari, 1947: 285, by original designation.
Diagnosis
Brueelia (Painjunirmus) is close to Brueelia (Brueelia) based on the following shared characters: as3, pns and s4 absent; dorsal preantennal suture absent and marginal carina uninterrupted [except in Br. (Br.) phasmasoma Gustafsson & Bush, 2017]; mts3 only temporal macroseta; fII- v2 and fIII-v2 absent; parameral heads not folded medianly; female subgenital plate forming cross-piece at vulval margin; post-spiracular sensilla present on abdominal segments II–VII in both sexes.
These two subgenera are separated by the following characters: antennae at least slightly sexually dimorphic in Br. (Painjunirmus) (Figs 3–4), but monomorphic in Br. (Brueelia); fI-v4 clearly shorter than fI-v 1 in Br. (Painjunirmus) (Fig. 1), but as long as fI-v 1 in Br. (Brueelia); aps present on male tergopleurite IV in Br. (Painjunirmus) (Fig. 1; also on tergopleurite III in some species; Fig. 9), but absent on male tergopleurite IV in Br. (Brueelia) [except in Brueelia (Br.) nebulosa (Burmeister, 1838)]; ames sensilla present on gonopore in Br. (Painjunirmus) (Fig. 6), but absent in Br. (Brueelia); mesosomal lobes with antero-lateral “horns” in Br. (Painjunirmus) (Fig. 6), but no such “horns” in Br. (Brueelia).
Brueelia (Painjunirmus) is also rather similar to the genus Teinomordeus Gustafsson & Bush, 2017. These two groups share the antero-lateral “horns” of the mesosome, the slightly sexually dimorphic antennae, and the patterns of abdominal chaetotaxy of the male. However, these two groups can be separated by the following characters: cross-piece present in Br. (Painjunirmus) (Fig. 8), but absent in Teinomordeus; head sensillus s4 present in Teinomordeus, but absent in Br. (Painjunirmus) (Fig. 3); ps are present on female abdominal segment II in Teinomordeus, but absent in Br. (Painjunirmus) (Fig. 2); pmes present on gonopore in Br. (Painjunirmus) (Fig, 6), but absent in Teinomordeus.
Description
Both sexes
Head dome-shaped (Fig. 3), slightly variable between species. Lateral margins of preantennal head slightly convex to more or less straight. Frons concave, hyaline. Marginal carina uninterrupted, displaced and much widened at osculum. Head chaetotaxy as in Fig. 3; as3, pns, s4 absent; pos on or near eye. Antennae sexually dimorphic, with male scape (Fig. 3) at least slightly swollen and elongated compared to female scape (Fig. 4), but varying degree of difference among species. Temporal and occipital carinae not visible. Prothorax rectangular, psps on postero-lateral corner (Figs 1–2). Pterothorax roughly trapezoidal, but with rounded or slightly convergent posterior margin; mms moderately separated medianly. Meso- and metasterna not fused, each with 1 seta on each side on postero-lateral corners. Male tergopleurites II–IX+X and female tergopleurites II–VIII divided medianly (Figs 1–2). Tergopleurites with no or only very small antero-lateral re-entrant heads (Figs 1–2). Sternal plates with concave lateral margins (Fig. 26), in some species with lateral modifications (Figs 1–2). Accessory sternal plates absent. Pigmentation largely translucent except for sternal and subgenital plates of abdomen, gular plate, and lateral margins of head; extent of dark pigmentation variable between species, and indicated with grey lines in illustrations.
Male
Abdominal chaetotaxy rich (Fig. 1), variable among species; aps on at least tergopleurites IV–VII; tps on at least tergopleurites VI–VIII, in some species on V. Basal apodeme variable in size and shape (Figs 5, 13, 21, 29, 37). Proximal mesosome extended to overlap with basal apodeme. Antero-lateral corners of mesosomal lobes extended into “horns” (Fig. 6); distal mesosome intensely rugose; 2 pmes sensilla on each side of gonopore, associated with paler area of mesosomal lobes. Gonopore roughly crescent-shaped, with 3 ames sensilla on each side. Penile arms slender (Fig. 6). Parameral heads broad, blunt (Fig. 7). Parameral blades much elongated; pst1 sensillus, central; pst2 microsetae, on lateral margin.
Female
Abdominal chaetotaxy sparse (Fig. 2); aps, tps, and ss absent on all segments; psps present only on tergopleurites VI–VII. Subgenital plate with more or less sinuous lateral margins (Fig. 8), connected to cross-piece. Few slender vms and many thorn-like vss along vulval margin; few vos on each side of subgenital plate; distal 1 vos median to vss and separated from other vos by pronounced gap.
Host distribution
Only known from hosts in the genus Argya (Passeriformes: Leiothrichidae).
Geographical range
Africa, Middle East, India, Myanmar [?].
