Ololaelaps tasmanicus  .— Babaeian et al., 2019b: 352 View Cited Treatment ; Beaulieu et al., 2019: 5.

Specimens examined. Six females, four males; 27°11’ N, 31°09’ E, Abutig, Assiut; 01 April 2015; coll. A.S. Abdelgayed; ex. soil under grapefruit.

Remarks. Ololaelaps tasmanicus  was described as Pristolaelaps tasmanicus  , which had been collected from leaves of strawberry plants ( Womersley, 1956). The description of this species is brief and lacks many important details, but additional morphological characters that complement the description of this species are recently presented by Babaeian et al. (2019b). They also synonymised O. paratasmanicus  and O. tasmanicus  , this decision was based on comparing the descriptions and figures of these species. We followed Babaeian et al. (2019b) and keep them as synonyms. Ololaelaps bregetovae  was described from debris in Egypt ( Shereef & Soliman, 1980). This species is also very similar and shares almost all important character states with O. tasmanicus ( Beaulieu et al., 2019)  . We were unable to examine the type specimens of O. bregetovae  , but by comparing the descriptions and figures of these species we could not find any distinguishing authentic morphological differences. Therefore, we suspect that Ololaelaps bregetovae  may be a junior synonym of Ololaelaps tasmanicus  . Our specimens of O. tasmanicus  agree completely with Babaeian et al. (2019b, Figs 1–15View FIGURES 1–5View FIGURES 6–10View FIGURES 11–18). This species was described based on adult female. The male is described herein for first time.

Description. Male (n=4). ( Figs 47–50View FIGURES 43–48View FIGURES 49–50).

Dorsal idiosoma. Dorsal shield (554–567) long, (298–315) wide; ornamentation and chaetotaxy as in female ( Fig. 43View FIGURES 43–48).

Ventral idiosoma ( Fig. 49View FIGURES 49–50). Sternal, genital, endopodal, exopodal, parapodal, ventral and anal shields fused into holoventral shield, strongly sclerotised throughout, bearing st1-5, five pairs of opisthogastric setae (Jv1–Jv3, Zv2, Zv3) in addition to circumanal setae; six pairs of poroids and a pore-like (gv3) laterad para-anal setae. Peritrematal shield free, soft opisthogastric cuticle with five pairs setae and metapodal element merged with holoventral shield.

Gnathosoma  . Epistome and subcapitulum similar to female ( Fig. 45View FIGURES 43–48). Fixed digit of chelicera with one median tooth and large distal hook, pilus dentilis slender. Movable digit of chelicera with one median tooth, spermatodactyl 0.7× as long as movable digit, strongly angled, variously bent, with a large distal knob, duct discernable ( Figs 48View FIGURES 43–48 & 50View FIGURES 49–50), fringed hyaline arthrodial process at base of movable digit ( Figs 48View FIGURES 43–48 & 50View FIGURES 49–50). Palps similar to those of female.

Legs. Without a spine-like seta on femur II; pv thickened on both genu and tibia III, av2 on tarsus II spatulate-truncate ( Fig. 47View FIGURES 43–48) and pd spine-like on femur IV, other segments as in female (see Babaeian et al. 2019b, Figs 8–11View FIGURES 6–10View FIGURES 11–18).
