464587D18B49FFDAFEFFFCA0FB86FE77.taxon	materials_examined	Type species. Tydeus triophthalmus Oudemans, 1929. Diagnosis Adults. André (1985) examined the type species T. triophthalmus (Oudemans) and redefined the genus and synonymized his genus Metatriophtydeus (Andre´, 1980) with Triophtydeus. Originally the genus was only characterized by the presence of three eyes, which are absent in most cleared specimens. This genus can be defined as follows: prodorsum with three pairs of eyes (not always visible) and four pairs of setae, including a pair of trichobothria; opisthosoma with eight pairs of setae and four pairs of slit-like pores or cupules, namely ia halfway between setae c 1 and d, im halfway between d and e, and ip lateral to setae f 1, a fourth pore (ih) is lateral to setae ps 1, posteroventrally; genital area with four to six pairs of genital setae (g), four to five pairs of aggenital setae (ag), two pairs of eugenital setae (eu) in female and six in male and two pairs of anal setae (ps); epimeral formula in adults (coxal plus ventral setae): 3 - 1 - 3 - 3; leg chaetotaxy (with solenidia in parentheses): tarsi 10 (ω) - 6 (ω) - 5 - 5, tibiae 5 - 2 - 1 - 2, genua 3 - 2 - 2 - 2, femora 5 - 4 - 1 - 1 + 2, trochantera 1 - 1 - 1 - 0, femur IV is divided. Twenty-nine species were originally placed in Triophtydeus. However, besides the type species, only four others fit this new definition, namely T. craυeni Wood, 1965, T. flatus Livshitz, 1973 (Kuznetzov and Livshitz 1973), T. immanis Kuznetzov, 1973 (Kuznetzov and Livshitz 1973), and T. lebruni Andre´, 1980. André (1985) opined that T. lebruni and T. triophthalmus are conspecific but maintained the status quo until a thorough revision of the genus could be contemplated. An examination of the paratypes of T. flatus indicated that the latter and T. triophthalmus may also be conspecific. South African specimens were compared with the type of T. immanis and resemble the latter in all respects, thus until DNA studies can be conducted we are left with no other choice but to consider them conspecific, and this is also the first record of this species from South Africa.	en	Ueckermann, Edward A., Grout, Timothy G.

464587D18B41FFD0FE30FA3BFB0EFC71.taxon	description	Orthotydeus munsteri (Meyer and Ryke); André 1980, p 127. Material examined South Africa: Mpumalanga Province: one female, four males, and three tritonymphs from Citrus sp., Lowveld Agricultural College, Nelspruit (25 ° 26.39 S, 30 ° 58.89 E), 14 August 2002, T. G. Grout. Northern Cape Province: three females and one male from Citrus sp., Kuruman (27 ° 26.69 S, 23 ° 25.69 E), 13 May 2003, T. G. Grout. Meyer and Rodrigues (1966) also recorded this species on citrus from Grahamstown (Eastern Cape Province), Buffelspoort (North-West Province), Kiepersol (Mpumalanga), Durban and Richmond (KwaZulu-Natal), and Swaziland. Diagnosis Adults. For an unknown reason Baker (1970) placed this species in his subgenus T. (Afrotydeus), with four pairs of genital setae, in spite of the fact that Meyer and Ryke (1959) clearly stated that T. munsteri has the same number of genital setae as T. grabouaei Meyer and Ryke, namely six. Perhaps the type specimen he studied was a tritonymph. This species is characterized by the following combination of characters: all dorsal setae, except for υi and υe, short and spatulate and pointed distally, sce also appear pointed distally in some specimens. Setae sci longest and slightly spatulate distally. Tydeus spathulatus (Oudemans) (Figures 13 – 19)	en	Ueckermann, Edward A., Grout, Timothy G.

Dorsum (Figures 13 – 15): all dorsal setae slightly serrated (Figure 14), except for setae e 1 – 2, f 1 – 2, and h 1 which are spatulate (Figure 15) and serrate; however, d 2 can also be spatulate in some specimens. Setae sci slightly longer than other dorsal setae. Prodorsum with four pairs of setae, opisthosoma with nine, only cupule ia could be detected. Striae with minute spikelike tubercles. Striae longitudinal on propodosoma and transverse medially on opisthosoma. Venter (Figure 16): epimeral formula 3 - 1 - 4 - 2. Genital area with four pairs of aggenital and six genital setae and no eugenital setae. Striae immediately lateral to progenital opening smooth, not tuberculated. Only one pair of anal setae (ps) present and paraproctal suckers well developed. Cupule ih lateral to paraproctal suckers. Gnathosoma (Figure 17): palp chaetotaxy (tarsus to trochanter): 6 (ω) - 2 - 2 - 0. Setae ba shortest, solenidion ω minute. Legs (Figures 18, 19): chaetotaxy of leg segments: tarsi 8 (ω) - 6 (ω) - 5 - 5, tibiae 4 - 2 - 2 - 2, genua 3 - 2 - 1 - 1, femora 3 - 2 - 1 - 1, trochantera 1 - 0 - 1 - 0. Femur IV entire. All tarsi terminate in two claws and a hairy empodium. Coxa I with coxal organ. Male (n 51). Dimensions of Israeli specimen: length of idiosoma (including gnathosoma) 315, width 192; setae: υi 22, υe 25, sci 33, sce 32, c 1 28, c 2 32, d 1 28, d 2 28, e 1 28, e 2 28, f 1 32, f 2 28, 16, h 25, ps 22; cheliceral stylets 19; palp tarsus 23. Similar to female but differs in that the genital area has four pairs of aggenital, six pairs of genital, and four pairs of eugenital setae. Paraproctal suckers well developed. Coxa I with coxal organ. Tritonymph (n 52). Dimensions (measurement of Israeli specimen in parentheses): length of idiosoma (including gnathosoma) 265 (302), width 173 (180); legs: I 199 (183), II 177 (170), III 157 (151), IV 173 (173); setae: υi 16 (19), υe 19 (19), sci 28 (?), sce 22 (25), c 1 16 (22), c 2 22 (25), d 1 19 (22), d 2 22 (25), e 1 22 (25), e 2 22 (28), f 1 22 (25), f 2 22 (25), h 16 (22), ps 16 (19); cheliceral stylets 13; palp tarsus 22. Tritonymph differs from adults by lacking a progenital aperture, which is represented by two pores, presence of four pairs of aggenital, three pairs of genital, and one pair of anal setae. Paraproctal suckers well developed. Coxa I with coxal organ. Remarks The South African specimens resemble the redescription of T. spathulatus (André 2005) in all respects. Tydeus californicus (Banks) may be a junior synonym of T. spathulatus because it corresponds to the redescription of the latter in all respects; five pairs of lanceolate / clavate dorsal setae posteriorly, striae arrangement of genital area and blunt setae on genua III and IV. This is a new record for South Africa. Figures 20 and 21 show how the setae of T. grabouaei Meyer and Ryke, the closely related South Africa species, differ from that of T. spathulatus.	en	Ueckermann, Edward A., Grout, Timothy G.

464587D18B5DFFCDFE45FEA4FCACFE14.taxon	materials_examined	Type species. Kakamasia cataracta sp. n. Diagnosis Adults. This new genus is closely related to Pronematulus Baker, Pronematus Canestrini, and Homeopronematus Andre´. It differs from them all in that femur IV is divided (however, femur IV may be divided in some species of Pronematulus), and in the setal formula of the tarsi, namely 8 (ω) - 6 (ω) - 6 - 5, as opposed to 8 (ω) - 7 (ω) - 6 - 6 in Pronematulus, 8 (ω) - 6 (ω) - 5 - 5 in Pronematus, and 8 (ω) - 6 (ω) - 6 - 6 in Homeopronematus. It further differs from Pronematus and Homeopronematus in that genu II has three setae instead of two. Femur IV of both Pronematus and Homeopronematus bears two setae, instead of one seta as in Kakamasia. Kakamasia bears setae on trochantera I and II, whereas Pronematus has none. This monotypic genus can be defined as follows: dorsum of idiosoma with 14 pairs of setae including a pair of trichobothria (sci); tarsus I without apotele; poroidotaxy: four (ia, im, ip, ih); genital organotaxy: 0 - 0 - 4 (eugenital (eu) - genital (ge) - aggenital (ag) setae); solenidiotaxy: three (tarsi I and II and tibia I); epimeral formula: 3 - 1 - 4 - 2 (ventral plus coxal setae); chaetotaxy of some leg segments: tarsi 8 (ω) - 6 (ω) - 6 - 5, genua 3 - 3 - 2 - 1, femora 3 - 3 - 2 - 1 + 0, and trochanters 1 - 1 - 1 - 0. Femur IV divided. Anal opening extends posterior to ps 3 to form a lobe. Etymology The genus name refers to the town close to the locality where this species was collected and its gender is feminine. Kakamasia cataracta sp. n. (Figures 22 – 25) Type material South Africa: Northern Cape Province: one holotype female, from Citrus sinensis (Delta Valencias), Augrabies near Kakamas (28 ° 39.99 S, 20 ° 27.59 E), 14 May 2003, T. G. Grout. Accession number: Acy: 03 / 244. Diagnosis The diagnostic characters of this species are the same as those defining the genus. Female (n 51). Dimensions of holotype: length of idiosoma 302, width 167; legs: I 158, II 154, III 177, IV 177; setae: υi 16, υe and c 25, sci 47, sce, d and h 1 32, e and f 1, f 2 63, h 2 54, ps 1 22, ps 2 44, ps 3 13; cheliceral stylets 13; palptarsus 16. 1 – 2 Dorsum (Figure 22): prodorsum with four pairs of setae, including trichobothrium (sci), υi is the shortest and υe situated posteromedially to sci. Opisthosoma with 10 pairs of setae and three pairs of cupules (ia, im, ip). All setae setose. Striae longitudinal on prodorsum and diagonal to longitudinal from setae c 1 to d and transverse from d to behind f 1 – 2. Venter (Figure 23): epimeral formula 3 - 1 - 4 - 2. Genital area with four pairs of aggenital setae. Eugenital and genital setae absent but three pairs of anal setae (ps) present, only ps 3 situated ventrally. Anal opening extends posterior to ps 3 to form a lobe. Ventral cupule ih close to setae ps 2. Gnathosoma (Figure 24): palp chaetotaxy (tarsus to trochanter): 5 (?) - 1 - 2 - 0. Solenidion minute, setae pζ and d apparently forked distally. Legs (Figure 25): chaetotaxy of leg segments: tarsi 8 (ω) - 6 (ω) - 6 - 5, tibiae 4 (ϕ) - 2 - 2 - 2, genua 3 - 3 - 2 - 1, femora 3 - 3 - 2 - 1 + 0, and trochantera 1 - 1 - 1 - 0. Solenidion ϕ and setae k are closely associated. All leg setae slightly serrated. Femur IV divided. Distal third of four terminal setae on tarsus I smooth. Tarsi II – IV each terminates in two claws and a hairy empodium. Solenidion on tarsus I short (9) but extends to anterior margin of tarsus. Coxae I without coxal organs. Etymology The species name cataracta is derived from the Greek word kataraktes (5 waterfall), which refers to the Augrabies Waterfall close to the collection site.	en	Ueckermann, Edward A., Grout, Timothy G.

G. Grout. Diagnosis 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 (n 51). 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): 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): 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): palp chaetotaxy 5 - 1 - 2. Solenidion on tibiotarsus, setae pζ and d apparently forked distally. Legs (Figures 28, 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. Remarks 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. Etymology The species name refers to the place where this species was collected, namely Augrabies.	en	Ueckermann, Edward A., Grout, Timothy G.

Accession numbers: AcY: 02 / 59, 03 / 27 – 30, 03 / 32, 03 / 34 – 36, 03 / 38 – 40, 03 / 226, 03 / 228, 03 / 231 – 232, 03 / 239 – 240, 03 / 242 – 245, 03 / 247 – 249, 03 / 253, 03 / 264, 03 / 273. Diagnosis Adults. This species can be distinguished by the following combination of characters: tarsus I as long as or longer than tibia I, two of terminal setae on tarsus I longer than segment and all terminal setae serrated along entire length; members of ventral setae half as long as distance between them and longitudinally aligned. Remarks The identification of the South African specimens as P. ubiquitus was based on reference material identified as such by the late Dr Smith Meyer. She studied the type specimens of P. ubiquitus in 1970 and identified the South African specimens accordingly. At present the condition of the type material renders an examination impossible (Dr Ron Ochoa, personal communication). This species appears to be the dominant species in citrus orchards in southern Africa.	en	Ueckermann, Edward A., Grout, Timothy G.

464587D18B5BFFC9FE63FC40FC9BF961.taxon	materials_examined	Type species. Lourus testatus (Kuznetzov, 1972). Diagnosis Adults. This new genus is closely related to Neopronematus Panou et al. but differs from the latter in that setae h 2 and ps 2 are present. The leg chaetotaxy of both genera is the same. Panou et al. (2000) based Neopronematus on two of Kuznetzov’s (1972) species, namely Pronematus rapidus and P. neglectus, with the former as type species, and a new species they described from Greece. They ignored P. testatus Kuznetzov which, along with L. citricolus sp. n., differs from Neopronematus in bearing dorsal seta h 2 and anal seta ps 2. This new genus can be defined as follows: propodosoma with four pairs of setae, including trichobothria (sci), opisthosoma with 10 pairs of setae (including ps 1 – 2), posterior margin with a lobe; this lobe is also present in the type species L. testatus (Dr A. Khaustov, personal communication); poroidotaxy: 4; genital organotaxy: 0 - 0 - 4; solenidiotaxy: 3; epimeral formula 3 - 1 - 4 - 1 or 2, palp chaetotaxy 5 - 1 - 1 or 2; chaetotaxy of trochantera 1 - 1 - 1 - 0. Differences in setation of coxae IV and the palp femur are regarded as significant at species level. Etymology The genus name is derived from the Latin word lobus meaning lobe and the Greek word oura meaning tail and refers to the posterior lobe of the opisthosoma of L. citricolus; L. testatus also have a small lobe. The gender is masculine.	en	Ueckermann, Edward A., Grout, Timothy G. (2007): Tydeoid mites (Acari: Tydeidae, Edbakerellidae, Iolinidae) occurring on Citrus in southern Africa.

Genital area with only four pairs of aggenital setae. Three pairs of anal setae, ps 1 – 2 dorsally situated. Cupule ih mediolaterally located on an imaginary line connecting fourth pair of aggenital setae and ps 3. All ventral setae and aggenital setae stout, except for the slender ag 4. Gnathosoma (Figure 32): palp chaetotaxy (tarsus to trochanter) 5 - 1 - 1 - 0. A solenidion may be present but could not be detected.

Tarsus I without apotele, tarsi II – IV terminate in two claws and a hairy empodium. Solenidion v 1 proximally on tarsus II. Coxa I without coxal gland. All leg setae, including four long terminal setae on tarsus I, slightly setose. Etymology The species name is derived from the Latin words Citrea for Citrus and colus meaning daeelling in.	en	Ueckermann, Edward A., Grout, Timothy G.
