Redescription (based on holotype; 2 Iranian and 1 Pakistani specimen in parentheses)

Larva: Dorsal surface with ~50 (~76, 80, 76) [fD] finely barbed and tapering setae placed on small platelets, two setae anterior of eyes; crista present with anterior and posterior sensillary areas placed on weak dorsal scutum. Dorsal scutum narrow, smooth, longitudinal but widest at level of PL setae. Dorsal scutum with 2 pairs of normal setae (AL and PL), both finely barbed ( Figs. 1 View FIGURES 1 – 3 , 9 View FIGURES 7 – 9 ). Anterior end of scutum rounded, posterior pole a blunted point. Scutum carries linear, rod-like crista. Anterior sensillary area triangular, and carries a pair of sensilla (ASens) which is barbed along entire stem. Posterior sensilla (PSens) similar to anterior sensilla but longer, situated at posterior part of crista. One eye on each side of scutum, circular, situated behind middle of dorsal scutum ( Fig. 1 View FIGURES 1 – 3 ).

Idiosoma ventrally with 18 (18, 19, 14) setae between coxae II and III and 30 (28, 27, 28) setae behind of coxae III (fV = 48 (46, 46, 42)), all finely barbed, tapering and pointed ( Fig. 2 View FIGURES 1 – 3 ). NDV = ~50 (~76, 80, 76) + 48 (46, 46, 42) = ~98 (~122, 126, 118). Sternalae 1a, 2a and 3a similar to other ventral setae. Coxae I, II & III, each with 1 finely barbed and pointed seta. Supracoxal seta of leg I peg-like.

Gnathosoma with a nude galeala (cs) and two hypostomalae, anterior hypostomala (as) normal, nude (tiny, thorn-like in Pakistani specimen), posterior hypostomala (bs) barbed ( Figs. 3 View FIGURES 1 – 3 , 8 View FIGURES 7 – 9 , 10 View FIGURES 10 – 11 ). Cheliceral blade with small tooth on lateral part. Palpal trochanter with 1 seta, femur with 3 and genu with 5 barbed and pointed setae; palpal tibia with 1 weakly barbed and 2 nude setae. Palptarsus with 1 eupathidium, 1 solenidion and 5 nude setae. Palpal tibial claw entire with small median dorsal and small median ventral tooth ( Figs. 3 View FIGURES 1 – 3 , 7 View FIGURES 7 – 9 ). fPp = B-BBB-BBBBB- BNN-NNNNNωζ; cheliceral basis and subcapitulum punctate. Supracoxal seta (eP) peg-like.

Leg lengths (including coxae, excluding claws): Leg I 376 (414–433, 341-421) leg II 336 (346–353, 271-346) leg III 386–401, 321-400); IP= 1146–1187.

Leg segmentation formula: 7–7–7. Leg setal formula: Leg I: Ta- 1ω, 2ζ, 1z, 20n (23 in holotype); Ti- 2φ, 1κ, 11–12n; Ge- 1σ, 1κ, 10n; TFe- 5n; BFe- 4n; Tr- 2n ( Fig. 4 View FIGURES 4 – 6 ). Leg II. Ta- 1ω, 2ζ, 1z, 19–20n; Ti- 2φ, 11n; Ge- 1κ, 10n; TFe- 5n; BFe- 3n; Tr- 3n ( Fig. 5 View FIGURES 4 – 6 ). Leg III. Ta- 1ζ, 20n; Ti- 1φ, 11n; Ge- 9n; TFe- 5n; BFe- 3n; Tr- 3n ( Fig. 6 View FIGURES 4 – 6 ).

Pedotarsal claws normal, anterior claw and empodium falciform, simple and posterior claw pulvilliform.

Abnormalities: One specimen from Iran, on one side of Ta III, 18 setae (instead of 20) and on one side of Ge III, 10 setae (instead of 9). Specimen from Pakistan, on one side of Ti II, 10 setae (instead of 11). In the holotype specimen, the seta anterior to the eyes on one side is longer than the other.

Measurements are given in Table 1 View TABLE 1 .

Remarks. Corrections to the original species description

We studied the holotype of P. kovalamicus and found that the following characters should be corrected in the original description: scutum present (absent in original description) ( Fig. 9 View FIGURES 7 – 9 ); number of setae on BFe I and II is 4 (3 in original description), microseta present on Ge I and II and Ti I (absent in original description); number of solenidia on Ti I is 2 (3 in original description), companion seta (z) on Ta I and II present (absent in original description); number of normal setae on Ta I is 23 (14 in original description); number of normal setae on Ge I, Ti I and Ta I is 10, 11 and 19 respectively (9, 10 and 14 in original description, respectively); palpal setal formula is as follows: B-BBB-BBBBB-BNN-NNNNNωζ (B-BB-BBBB-BB?N-NNNNωζ in original description). Haitlinger (2002) considered that the three pairs of scutalae (AL, ML and PL) were all in soft membrane for the genus, even though Womersley (1934) and Southcott (1961) clearly showed that the scutum is present and bears two pairs of scutalae. Here, we show that the genus Pollux has two pairs of scutalae on the scutum, and two pairs in soft cuticle, as reported by Womersley (1934) and Southcott (1961). Naming these setae is problematical. Here, we consider the anterior scutalae AL and the posterior scutalae PL, that ML has been lost, and that the two setae in soft cuticle are hypertrichous additions. Another interpretation would be that AL and ML are on the scutum, and PL is off the scutum, and that only one pair of setae is a hypertrichous addition. Due to our nomenclatural change, the PW is 38, not 70 as in the original description of P. kovalamicus .
