Type material

South Africa: Northern Cape Province: one holotype female, from Citrus sinensis (Delta Valencias) , Augrabies near Kakamas (28 ° 39.99S, 20 ° 27.59E), 14 May 2003, T. G. Grout GoogleMaps .


Adults. This species can be recognized by setae υi (16) which are shorter than half the length of sci (47), υe (25) almost half its length, and sce (38) longer than half its length.

Female (n51). Dimensions of holotype: length of idiosoma 299, width? (specimen in lateral position); legs: I 154, II 145, III 152, IV 169; setae: υi 16, υe, c 1, c 2, and h 1 25, sci 47, sce and f 2 38, d, e, and ps 1 22, f 1 19, h 2 50, ps 2 41, and ps 3 13; cheliceral stylet 14; palp tarsus 16.

Dorsum ( Figure 26 View Figures 26–29 ): prodorsum with four pairs of setae, sci a trichobothrium, setae υe posteromedially to sci. Opisthosoma with 10 pairs of setae. All setae slightly setose. Three pairs of cupules present, ia between setae c 1 and d, im anterior to e, and ip close to f 2. Striae longitudinal on prodorsum and extend past setae d on opisthosoma, but from anterior of e to level h they are transverse.

Venter ( Figure 26 View Figures 26–29 ): epimeral formula 3-1-4-2. Genital area with four pairs of aggenital setae. Eugenital and genital setae absent. Anal setae ps 1–2 placed dorsally, ps 3 ventrally. Cupule ih lateral to ps 2.

Gnathosoma ( Figure 27 View Figures 26–29 ): palp chaetotaxy 5-1-2. Solenidion on tibiotarsus, setae pζ and d apparently forked distally.

Legs ( Figures 28, 29 View Figures 26–29 ): chaetotaxy of leg segments: tarsi 8(ω)-7(ω)-6-6, tibiae 3(ϕ)-2-2-2, genua 3-3-2-1, femora 3-3-2-1+1, trochantera 1-1-1-0. All leg setae slightly setose. Femur IV divided. Tarsus I with four long and smooth setae. Tarsi II–IV each with two claws and a hairy empodium. Solenidion ω 1 11 long and extends slightly past anterior margin of tarsus I. Coxae I without coxal glands.


This species is closely related to the type species, P. acus , which differs from P. augrabiensis in that υi, υe, and sce are shorter than half the length of sci while only setae υi are shorter than half the length of sci in P. augrabiensis . Most opisthosomal setae of P. augrabiensis are relatively longer than those of P. acus . Apparently only setae sci are setose whereas the rest of the dorsal setae are smooth in P. acus . Unfortunately, the description of P. acus lacks enough detail, which renders a thorough comparison of these species impossible. Pseudopronematulus augrabiensis is the second species described for this genus.


The species name refers to the place where this species was collected, namely Augrabies.
