Figs 71–77
Diagnosis
Brueelia celer sp. nov. is most similar to Br. pseudognatha Gustafsson & Bush, 2017, with which it shares the following characters: abdominal segments IV and VII in both sexes with 1 ps on each side (Figs 71–72); female abdominal segment VI with only 1 ps on each side (Fig. 72); male tergopleurite IV without aps, male tergopleurite VIII with tps (Fig. 71); overall shape of proximal mesosome rather broadly rounded (Fig. 76); vulval margin convergent to median point (Fig. 77).
These two species can be separated by the following characters: male tergopleurite VIII with 2 tps on each side in Br. pseudognatha, but with only 1 tps on each side in Br. celer sp. nov. (Fig. 71); proximal mesosome gently rounded in Br. pseudognatha, but with median bulge in Br. celer sp. nov. (Fig. 76); parameres proportionately more elongated in Br. celer sp. nov. (Fig. 75) than in Br. pseudognatha; gonopore crescent shaped in Br. celer sp. nov. (Fig. 76), but rounded in Br. pseudognatha; mesosomal lobes broader in Br. pseudognatha than in Br. celer sp. nov. (Fig. 76); differences in shape of female subgenital plate (Fig. 77).
Etymology
The species name is derived from the Latin ‘ celer ’ for ‘swift’, referring to the sleek, slender appearance of this species.

Description
Both sexes
Head convex dome-shaped (Fig. 73), lateral margins of preantennal head convex, frons rounded to slightly flattened. Marginal carina slender, moderately displaced and translucent but not widened at osculum, median margin undulating. Ventral anterior plate not visible. Head chaetotaxy as in Fig. 73; pos located near posterior margin of eye. Temples rounded, occiput slightly convex. Thoracic and abdominal segments as in Figs 71–72. Base pigmentation pale brown, darkening at median margin of marginal carina, margins of antennal socket, lateral section of postantennal head including pre- and postocular nodi and marginal temporal carina, proepimera, metepisterna, and lateral sections of tergopleurites.
Male
Thoracic and abdominal chaetotaxy as in Fig. 71. Basal apodeme long (Fig. 74), constricted at midlength, with rounded anterior margin. Proximal mesosome broad, rounded (Fig. 76). Mesosomal lobes slender, with restricted rugose area near medio-distal margin; 2 pmes sensilla on each side laterodistal to gonopore. Gonopore crescent shaped, stocky; no lateral extensions. Penile arms reach slightly beyond distal margin of mesosomal lobes. Parameres stocky, elongated distally; pst1–2 as in Fig. 75. Measurements as in Table 1.
Female
Thoracic and abdominal chaetotaxy as in Fig. 72. Subgenital plate long and slender (Fig. 77), with straight anteriora and lateral margins, distal connection to cross-piece broad. Vulval margin straightly convergent to rounded median point (Fig. 77), with 2–5 short, slender vms and 3–5 short, thorn-like vss on each side; 3–5 short, slender vos on each side of subgenital plate; distal 1 vos median to vss. Measurements as in Table 1.
Remarks
We found no significant differences between specimens from the two host subspecies, and consider specimens from both host subspecies to be conspecific.
