Etymology. We name this species bromelicola (from the Latin adjective meaning ‘inhabitant of bromeliads’) in reference to its host-plants, which belong to the family Bromeliaceae .

Description of adult female. Macroscopic appearance ( Fig. 1 ). Body of live adult female pale pink-orange, with a thin coating of powdery white wax on dorsum and paired lateral filaments of white wax on margins, filaments successively increasing in length gradually towards posterior end, with longest pair projecting from posterior-most segment. Color of body in alcohol pale pink-orange, not turning black or green when placed in ethanol or KOH.

Slide-mounted characters ( Fig. 2 ). Body of adult female oval, becoming larger and more rotund with age, 1.5 ± 0.4 [1.0] (0.9–2.3) mm long, maximum width (at metathorax) 0.9 ± 0.2 [0.6] (0.4–1.4) mm. Anal lobes moderately developed, each with an apical seta 142 ± 14 [152] (119–164) µm long. Antenna 241 ± 20 [222] (208–265) µm long, each with 7 segments. Legs well developed, hind tibia 97 ± 10 [92] (81–117) µm long, hind femur 107 ± 8 [110] (93–118) µm long, hind trochanter + femur 147 ± 12 [148] (124–164) µm long, hind tibia + tarsus 152 ± 14 [142] (131–181) µm long; claw well developed, 17 ± 2 [18] (14–19) µm long. Ratio of lengths of hind tibia + tarsus to hind trochanter + femur 1.0: 1.0 ± 0.05 [1.0: 1.0] (1.0: 0.9–1.0: 1.0). Ratio of lengths of hind tibia to tarsus 1.0: 1.7 ± 0.1 [1.0: 1.8] (1.0: 1.4–1.0: 2.0). Hind tibia distally with 5–10 [8] translucent pores, and hind coxa with 22–88 [29–32] translucent pores. Labium 86 ± 7 [75] (74–95) µm long (measured as l in Fig. 2 ); clypeolabral shield 125 ± 7 [119] (112–133) µm long (measured as c in Fig. 2 ); ratio of lengths of labium to clypeolabral shield 1.0: 1.5 ± 0.1 [1.0: 1.6] (1.0: 1.3–1.0: 1.7). Circulus present between SIII and SIV, undivided by intersegmental line, 40 ± 13 [45] (19–60) µm wide. Anterior and posterior ostioles moderately developed. Anal ring 63 ± 7 [64] (52–74) µm in diameter, with a double band of pores, bearing six setae, each seta 111 ± 8 [95] (95–124) µm long. Cerarii each containing 2 conical setae and a concentration of trilocular pores, numbering 12–14 pairs [13], present on all abdominal segments and on several cephalic and thoracic segments; if cerarii not recognizable, then 1 or more isolated marginal conical setae present in their positions. Anal lobe cerarii (C1) each containing 2 enlarged conical setae, each seta 18 ± 1.5 [19] (17–22) µm long, 2–4 auxiliary setae and a concentration of trilocular pores situated on a slightly sclerotized area; all other recognizable cerarii lacking auxiliary setae and situated on membranous cuticle.

Dorsum. Slender lanceolate setae of two lengths present: shorter setae each about 7.2 µm long; longer setae each about 14.3 µm long. Multilocular pores and OR absent. Discoidal pores, each slightly smaller than a trilocular pore, scattered and scarce. Trilocular pores evenly distributed except absent from segmental folds.

Venter. Setae normal, flagellate. Cisanal setae each 26 ± 3 [24] (21–29) µm long, obanal setae each 19 ± 2.5 [24] (15–24) µm long, anal lobe seta 142 ± 14 (119–165) µm long. Multilocular pores each 7.0 ± 0.4 µm [6.2] (6.2– 7.2) in diameter, present along margins from head to SVIII, sometimes present near front coxa, in medial area of abdomen on SV–VIII, and submedially on SIV–VII. Trilocular pores evenly distributed except absent from segmental lines and around coxal bases. Discoidal pores as on dorsum, scarce. OR absent. OC restricted to marginal areas, one per segment on head and thorax except for a small group opposite anterior coxa; on abdomen 1 per segment on SII and III, small groups of 2–6 OC of 2 sizes on SIV–VIII; larger type slightly wider than, and smaller type slightly narrower than a trilocular pore.
