Aleurodamaeus niedbalai View in CoL sp. nov.

( Figs 8 View FIGURE 8 B, 9)

Specific diagnosis. Aleurodamaeus niedbalai sp. nov. is most similar to A. angelae sp. nov., but is bigger in size, does not have a discidium and notogastral setae h1 is longer. Setae h1 and p1 is twisted and of medium size. The chitin-like structure around the famulus has a pincher-like form.

Measurements. Length: females (n = 5) mean 506 (range 488–532), males (n = 5) mean 457 (range 447–468). Width: females mean 273 (range 264–288), males mean 246 (range 238–254). Holotype (female): length 474, width 259.

Integument ( Figs 8 View FIGURE 8 B, 9A–D). Notogaster with three to four bands of solid cerotegument, cerotegument of diverse forms anterior on notogaster, cerotegument in the shape of the letter “n” on the prodorsum; body also covered with sparse spherical cerotegumental granules, body surface under cerotegument smooth; all body setae (except in) covered with small and large granules, sensillus with spine-like cerotegument; granules in bands on legs especially seen on Ti I, granules larger on legs itself than on the leg setae; exuvial scalps absent.

Prodorsum ( Fig. 9 View FIGURE 9 A). Rostrum rounded in dorsal view, slightly projecting in lateral view; ro (62), le (57) slender, curving medially, ro inserted posterior-ventrally to le in lateral view, le inserted on a small tubercle, in (11) spiniform, ex (23) thin, slender, inserted on distinct tubercle, anterior-laterally to bothridium; ss long (103), slender, smooth.

Notogaster ( Fig. 9 View FIGURE 9 A, C, D). Notogaster convex; distinct rim around notogaster; lyrifissures ia, im, ip slightly visible, ih, ips distinct, all of similar length (9); four pairs of notogastral setae on posterior edge, setae thin, smooth, h1 and p1 on distinct tubercles, seta p1 (110) longer than h1 (difficult to measure due to the ‘corkscrew shape’ but in general p1 a third to two thirds longer than h1); setae p2 and p3 shorter (21), not inserted on tubercles.

Gnathosoma . Subcapitulum longer than wide; hypostomal setae a, h, m strongly barbed; similar to A. vicinus sp. nov. ( Fig. 6 View FIGURE 6 E, F).

Epimeral region ( Fig. 9 View FIGURE 9 B). Sejugal apodeme well developed; number of setae on epimeres (from I to IV) 3-1- 3-3; all epimeral setae thin, weakly barbed, 2 a shortest (9) and 1b, 1c, 3c longest (33–36).

Anogenital region ( Fig. 9 View FIGURE 9 B). Genital setae of similar length (11–13), in a more or less straight line, weakly barbed; an short, spiniform, weakly barbed, similar length (16); ag (28) slender, similar to epimeral setae; ad3 (18) slightly shorter than ad2 (23); lyrifissure iad not evident.

Legs ( Fig. 8 View FIGURE 8 B). Leg IV (379)> leg I (341)> leg III (324)> leg II (236); legs similar to A. salvadordalii sp. nov. ( Table 1 View TABLE 1 , Fig. 3 View FIGURE 3 A–D); the chitin protection around the famulus in the shape of pinchers.

Etymology. The species is named in honour of Prof. Wojciech Niedbała from the Adam Mickiewicz University in Poland for his extensive contribution to the knowledge of ptyctimous mites in South Africa.

Type material. The holotype and 10 paratypes were sampled in the grassland biome, Eastern Cape GoogleMaps , between Hamilton and Rhodes GoogleMaps (30°45’S, 28°01’E) on a high mountain from soil under bushes by J.P. Eksteen on 3.xii.1993. The holotype ( NMB 3774.4.1) and GoogleMaps six paratypes ( NMB 3774.4) are deposited in the Acarology collection of the National Museum, Bloemfontein, South Africa. Four paratypes are deposited in the Staatliches Museum für Naturkunde Karlsruhe, Germany ( SMNK-ORIB 0498 ).

Collection data. Aleurodamaeus niedbalai sp. nov. is widespread across South Africa, but has a higher occurrence in the grassland biome. For distribution see Fig.10 View FIGURE 10 , indicated by filled stars.
