03CF87940026FFA7FF312765AF02FAA9.taxon	discussion	Remarks. Asca quinquesetosa was described from the nest of a booby on Clipperton Island (Wharton, 1941), and has been recorded from litter and moss in Hawaii (Hurlbutt, 1963) and New Zealand (Wood, 1966). It is now recorded from Cuba for the first time, from soil and litter. Our specimens agree very well with the description given by Hurlbutt (1963). There are two setae and two circular structures on each postero-dorsal tubercle (Figure 7), the epistome has two strong lateral points, and the margin between the points is slightly convex (Figure 6), all dorsal setae are minutely barbed and distance J 4 – J 4 is less than J 4 – Z 3 (Figures 1, 4, 5).	en	Joharchi, Omid, Halliday, Bruce, Tolstikov, Andrei V., Trach, Viacheslav A.

03CF87940024FFA3FF3123BEAA30FE31.taxon	diagnosis	Differential diagnosis. The new genus can easily be distinguished from other related members of the family by a combination of morphological attributes, some of which are unique or rarely observed in laelapid mites, such as (1) dorsal seta S 5 markedly elongated (2) very long dorsal setae (macrosetae) on femur and genu of legs I-IV (pd 1 on legs I & II and ad 1 on III & IV) (3) tibia III bears eight setae (2 1 / 1 2 / 1 1) (4) tarsus II – IV with subterminal blunt spines (al 1 and pl 1) (5) claws on pre-tarsi II – IV with a basal spur on their convex surface; (6) peritrematal shield broadly enlarged around stigmatic opening; (7) sternal shield reduced in size and longer than wide and bearing two pairs setae, st 1 off the shield; (8) opisthogastric area strongly hypertrichous. Females of the new genus are similar to Mumulaelaps Clark (in Clark & Hawke, 2012) in having the dorsal shield without lateral incisions, lateral soft skin strongly hypertrichous, sternal shield reduced in size and longer than wide and bearing two pairs setae, st 1 off the shield, legs I longer than II and III, elongated setae (macrosetae) on genua and femora I-IV (pd 1 on legs I & II and ad 1 on III & IV), tibia III bearing eight setae (2 1 / 1 2 / 1 1), and tarsus II-IV with subterminal blunt spines (al 1 and pl 1). The new genus differs from Mumulaelaps by the 28 pairs of dorsal shield setae (15 podonotal, 13 opisthonotal), with j – J and z – Z series complete (vs. 22 pairs (12 podonotal, 10 opisthonotal) and missing many setae from j – J and z – Z series in Mumulaelaps), setae S 5 greatly elongated and on dorsal shield (vs not markedly elongated and off the dorsal shield), setae Z 4 & Z 5 not markedly elongated (vs markedly elongated), opisthogastric area strongly hypertrichous (one pair of caudal setae greatly elongated, at least two-thirds of the body length) (vs. opisthogastric area hypotrichous in Mumulaelaps, lacking very long caudal setae), peritrematal shield broadly enlarged around stigmatic opening (Figure 27) and post-stigmatic section not conspicuous (vs. peritrematal shield normal and post-stigmatic section conspicuous in Mumulaelaps), one elongated seta (ad 1) (macroseta) on each genua III – IV, and tibia IV without elongated macrosetae (vs. two elongated setae (ad 1, pd 1) (macrosetae) on each genua III – IV and ad 1 on tibia IV elongated setae (macrosetae) in Mumulaelaps), and pre-tarsi II – IV with a basal spur on the inner surface of each tarsal claw (Figures 31 – 32). The last character state is otherwise unknown in the free-living Laelapidae, and appears to be autapomorphic for the new genus. The new genus is also very similar to Coleolaelaps. These two genera both have lightly sclerotised idiosomal shields, sternal shield reduced to leave small triangular endopodal fragments, sternal setae st 1 inserted in soft skin anterior to the sternal shield, and greatly elongated setae on the dorsal shield and some leg segments. These appear to be apomorphic character states in both genera. Most species of Coleolaelaps have a posteriorly reduced dorsal shield, which also appears to be apomorphic, but C. abnormalis Costa & Hunter, 1971 has a normal oval-shaped dorsal shield. Coleolaelaps brachysetus Costa & Hunter, 1971 has a posteriorly reduced dorsal shield, but is atypical in lacking greatly elongate setae on the dorsal shield and legs. These may be plesiomorphic character states in two early-derivative members of the genus. Acantholaelaps shares some derived character states with Coleolaelaps, but has a normal oval-shaped dorsal shield similar to that of C. abnormalis. However, Acantholaelaps differs from all species of Coleolaelaps in the presence of thick blunt setae on tarsus II, modified tarsal claws, the relative length of the legs (length of leg I longer than leg III vs. shorter than leg III in Coleolaelaps), and a short post-anal seta. The new genus is compared with other morphologically similar hypoaspidine genera associated with scarab beetles in Table 1. A full analysis of these character states must await the description of more beetle-associated species in genera similar to Coleolaelaps, Mumulaelaps, and Acantholaelaps.	en	Joharchi, Omid, Halliday, Bruce, Tolstikov, Andrei V., Trach, Viacheslav A.

(2019): New records and new species of mites from Cuba, with description of a new genus of Laelapidae (Acari: Mesostigmata). Zootaxa 4612 (3): 326-350, DOI: 10.11646/zootaxa.4612.3.2
03CF87940022FFABFF3125ECABCFFA3D.taxon	discussion	Remarks. The area of sclerotised cuticle between the sternogenital shield and anal shield in the male of Acantholaelaps strategus is very unusual. In the single available specimen this sclerite is irregular in shape, has the same surface texture as the sternogenital shield, and is not covered by striated soft skin. It may be a fragment of a reduced sternogenital / ventral shield, but confirmation must await the collection of more males. Female specimens of the new species show a remarkable range of variation in body size, length of medial dorsal shield setae, range of sclerotisation of the sternal shield, and the number of dorsal shield setae, but we believe that these differences represent intra-species variation. Costa & Hunter (1971) observed variation of this type in the related genus Coleolaelaps, and speculated that the variation might represent differences between clonal strains in species that appear to be thelytokous. Our collection of A. strategus includes 20 females and one male. These numbers suggest, but do not confirm, that this species reproduces by arrhenotokous parthenogenesis. The evolutionary significance of this intra-species variation would reward further study. The geographic distributions of species of Acantholaelaps and the other genera in Table 1 are probably influenced by the distribution of their specific hosts, depending on the degree of host specificity. The feeding habits of these mites are unknown, but they may be predators that feed on other small invertebrates in the microhabitats created by the beetles such as the hypopus stage of Astigmata mites. The presence of the new genus in Cuba supports the need for further exploration in this area. Acantholaelaps is apparently not endemic to Cuba, because a specimen has been collected in Brazil, but its distribution in surrounding countries remains unknown. The host beetle genus Strategus is widespread in the Neotropical Region and includes at least 31 species (Ratcliffe, 1976).

03CF8794002AFFB3FF31235FA933FEDD.taxon	etymology	Etymology. The specific name is derived from the type locality.	en	Joharchi, Omid, Halliday, Bruce, Tolstikov, Andrei V., Trach, Viacheslav A. (2019): New records and new species of mites from Cuba, with description of a new genus of Laelapidae (Acari: Mesostigmata). Zootaxa 4612 (3): 326-350, DOI: 10.11646/zootaxa.4612.3.2
03CF8794002AFFB3FF31235FA933FEDD.taxon	diagnosis	Differential diagnosis. According to Beaulieu (2009) and Kazemi et al. (2014), seta st 1 is outside the sternal shield in the presternal region in only a few species of Gaeolaelaps – G. aculeiferoides (Teng, 1982), G. debilis (Ma, 1996), G. krantzi (Arutunian, 1993), G. minor (Costa, 1968), and G. franzi (Van Aswegen & Loots, 1970). Gaeolaelaps cubaensis can be easily distinguished from all those species by its very long dorsal setae (most long enough to reach past base of next posterior seta in Gaeolaelaps cubaensis, but never reaching base of next posterior seta in the other species), and by its much smaller body size in comparison with other described species in this genus. In the classification of Karg (1982), G. cubaensis falls into the schusteri species group of Hypoaspis (Gaeolaelaps), because its genital shield is of normal size and shape and moderately separated from the anal shield, the posterior margin of the sternal shield is straight, the anal shield is wider than the genital shield, and the dorsal shield setae are long. These character states are shared with G. spiculifera (Berlese, 1918), from South Africa. Van Aswegen & Loots (1970) show the epistome of G. spiculifera as smooth, with only two anterior points, while that of G. cubaensis is strongly polydentate.	en	Joharchi, Omid, Halliday, Bruce, Tolstikov, Andrei V., Trach, Viacheslav A.

03CF87940032FFB3FF312797AA72F9A9.taxon	discussion	Remarks. Most of the published information on Pseudoparasitus missouriensis has been published under the name G. austriacus. It has been recorded many times, from North America, Europe and Russia. The species may be recognised by the relatively narrow exopodal plates behind coxa IV, very long and narrow metapodal plates, the very wide rounded genito-ventral shield, and a pair of opisthogastric setae in the soft skin between the genito-ventral and anal shields.	en	Joharchi, Omid, Halliday, Bruce, Tolstikov, Andrei V., Trach, Viacheslav A.
