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 1–15 View FIGURES 1–5 View FIGURES 6–10 View FIGURES 11–18 ). This species was described based on adult female. The male is described herein for first time.

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

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

Ventral idiosoma ( Fig. 49 View 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. 45 View 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 48 View FIGURES 43–48 & 50 View FIGURES 49–50 ), fringed hyaline arthrodial process at base of movable digit ( Figs 48 View FIGURES 43–48 & 50 View 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. 47 View FIGURES 43–48 ) and pd spine-like on femur IV, other segments as in female (see Babaeian et al. 2019b, Figs 8–11 View FIGURES 6–10 View FIGURES 11–18 ).
