Reticulolaelaps lativentris Karg, 1978: 26 .

Specimens examined — The two paratype specimens of Karg’s collection were examined by the first author: Slide ZMB Kat. Nr. 40559 ♀ and 40560 ♂, labelled Hypoaspis (Reticulolaelaps) lativentris Karg, 1978 , paratypus, Chile Umgebung von La Union (Prov. Valdivia). Modrige Erde aus feucht. Wald in tief. Tal. 26.10.1965.

Notes — Here are morphological features of P. lativentris that complement the original description of Karg (1978): The dorsal shield with 39 pairs of setae 21 podonotal, 17 opisthonotal, including three pairs of Zx setae between J and Z setae, and four unpaired median Jx setae; setae increasing in length from anterior to posterior, except Z5, shorter than surrounding setae; most setae long enough to reach well past base of next posterior seta. Dorsal shield wrapping around onto the ventral idiosoma, forming a marginal strip, except for the caudal end of the idiosoma. Genito-ventral shield very wide, bearing four pair of setae (including st5), with truncate posterior margin, and its surface reticulated. Hypostomal groove wide, with six rows of denticles each bearing 6-10 very small teeth, except the first row with four teeth, and a smooth anterior transverse line ( Fig. 3B ). The palp tarsal claw has two pointed tines of unequal length; palp trochanter setae simple, needle-like. Genu IV with nine setae (2 2/1 3/0 1), anteroventral seta spine-like. Male with sternal, genital, endopodal, ventral and anal shields fused into a holoventral shield, with nine pairs of setae and four pairs of poroids, with strong reticulation throughout. Unpaired post-anal seta shorter than para-anal setae, cribrum small, paranal gland pores not visible ( Fig. 3A ).
