One seta on terminal endopodal segment of leg 1 spinulose 

 (Figure 67C). Outer seta of fifth leg plumose and less well developed 

 (Figure 69B) than in female; sixth leg (Figure 69C,D) armed with 1 

 inner spine, about as long as second urosomal somite, bearing 

 spinular row at base, and 2 outer plumose setae, middle seta short 

 and stout. 



Variability. Specimens from Jureia Ecological Reserve and 

 Salesopolis were blackish in colour whilst specimens from Miracatu 

 were pale brown. 



Etymology. The species name is derived from the Bromeliaceae, 

 name of the family of plants providing a microhabitat for this 

 species, and from colere meaning to inhabit. It refers to the preferred 

 cryptic habitat of the species. 



Differential diagnosis. The new species can be differentiated 

 from other Pa racyclops species by the combination of the following 

 characters: by the long (almost twice as long as inner spine) and well 

 developed outer spinulose seta of leg 5 (Figure 65C ), by the structure 

 of the seminal receptacle (Figure 65B), by the absence of a mid- 

 distal spinular row on the posterior surface of leg 2 (arrowed in 

 Figure 67B) and leg 3 (arrowed in Figure 68B) and by the absence of 

 surface pits from the dorsal and ventral surfaces of all urosomal 

 somites except the genital double-somite, which has very fine 

 surface pits on the dorsal surface as figured (Figure 65A.B). 



Remarks 



P. bromeliacola is closely related to the other new Brazilian species, 

 P. rochai sp. nov. and P. punctatus sp. nov. They share the absence of 

 a mid-distal spinular row from the posterior surface of the coxa of 

 leg 2 and leg 3, and they all lack the spinular row near the base of the 

 two inner setae on the coxobasis of the antenna in both sexes 

 (arrowed in Figure 66C). However P. bromeliacola differs from P. 

 rochai and P. punctatus in the long (almost twice as long as inner 

 spine) and well developed outer spinulose seta of leg 5 (Figure 65C) 

 and in the structure of the seminal receptacle (Figure 65B). It also 

 differs from P. punctatus in the absence of surface pits from the 

 dorsal and ventral surfaces of the urosomal somites except the 

 genital double-somite of the female and genital somite of the male, 

 both of which have very fine surface pits on the dorsal surface as 

 figured (Figures 65A,B; 69A.D).

Description of adult female 



Body length (um) not including caudal setae, 630-711, mean = 

 681, n = 5; body width 274-309, mean = 292, n = 5. Genital 

 double-somite, second and third abdominal somites ornamented 

 with conspicuous surface pits on dorsal (Figure 70A) and ventral 

 (Figure 70B) surfaces as figured. Genital double-somite widest 

 anteriorly, narrowing posteriorly. Seminal receptacle as figured 

 (Figure 70B). Third and fourth urosomal somites with well-devel- 

 oped hyaline frill dorsally on posterior margin (Figure 70A). 

 Caudal rami 2.8 times longer than broad; with cuticular depres- 

 sions on ventral surface (Figure 70B); with inner margin convex 

 distally. Terminal accessory seta (VI) plumose and longer than 

 posterolateral seta (III); outer terminal seta (IV) and inner termi- 

 nal seta (V) well developed and heterogeneously ornamented 

 (Figures 70B; 72B). 



Antennule 8-segmented (Figure 71A,B). Segment 3 with two 

 partial suture lines on ventral and dorsal surfaces; with spiniform 

 seta distally. Segment 4 with partial suture line ventrally, extending 

 dorsally (Figure 71A,B). Segment 5 with characteristic short 

 aesthetasc. Setal formula 8, 12, 6, 5, 2 + aesthetasc, 2, 2 + aesthetasc, 

 7 + aesthetasc. Coxobasis of antenna with complex ornamentation 

 on caudal (Figure 71D) and frontal (Figure 71C) surfaces; without 

 spinular row on caudal surface near base of two inner setae (arrowed 

 in Figure 7 ID). 



Coxa of leg 1 without mid-distal spinular rows on posterior 

 surface (arrowed in Figure 72F); intercoxal sclerite without spinular 

 row on posterior surface; basis with spinular row on anterior surface 

 (arrowed in Figure 72H). Intercoxal sclerite of leg 2 ornamented 

 with spinular row on anterior (Figure 72G) and posterior (Figure 

 72E) surfaces; coxa without mid-distal spinular row on posterior 

 surface (arrowed in Figure 72E). Intercoxal sclerite of leg 3 with 2 

 spinular rows on posterior surface (Figure 72D); coxa without mid- 

 distal spinular row on posterior surface (arrowed in Figure 72D). 

 Intercoxal sclerite of leg 4 (Figure 72C) with 2 spinular rows on 

 posterior surface.
