All legs with welldeveloped ambulacra. Genital shield of female small and oval, similar to genital shield of male. Tritosternum with narrow basis and trifurcated. Gnathosoma: hypostomal setae long, with pilose margins. Corniculi horn-like. Internal malae pilose. Epistome marginally pilose. Chelicerae with internal sclerotized nodes, fixed digit without process.</p> <p>Remarks</p> <p>Only one genus (Macrodinychus Berlese, 1916) is known from this family.</p> <p>Distribution</p> <p>Circum-tropical, European, Australian and Middle-East.</p> <p>Notes</p> <p>In the last comprehensive work (Krantz and Walter 2009), Macrodinychus species were mentioned as members of the family Dinychidae (Lindquist et al. 2009). Unfortunately this statement [fixed cheliceral digit typically with a rounded or acuminate apical “finger” (see (Lindquist et al. 2009) on page 197], which can be found in the key to the family Dinychidae, is not true for the Macrodinychus species, where this character is lacking on their chelicerae (Hirschmann 1993). For this reason, I discuss these mites as a separate family.</p> <p>Biology</p> <p>Currently there is little information about the biology and ecology of these mites. Bal and Özkan (2005) reported viviparity in Macrodinychus bregetovaae Hirschmann, 1975 because they found about 30 larvae in the female’s body, but this phenomenon has not been recorded in other Macrodinychid species. One species of this family (Macrodinychus sellnicki Hirschmann and Zirngiebl-Nicol, 1975) is a well-known parasite of ant pupae (Gonzales et al. 2004; Vargas et al. 2004; Krantz et al. 2007), and presumably other species are associated with ant species or live in anthills, but we have no other information.</p> </div>	https://treatment.plazi.org/id/F25B87B2FFE8FFB92A57FAAA531EFB92	Public Domain	No known copyright restrictions apply.

However, Hirschmann’s categories are not recognized by the International Code of Zoological Nomenclature (ICZN 1999) so in the present work “Ganggattung” is regarded as genus, “Stadiengattung” as subgenus and “Stadiengruppen” as species-group (see Kontschán 2008).</p> <p>First, Hirschmann (1975a) subdivided the genus Macrodinychus into two “Stadiengattungen”, Macrodinychus and Monomacrodinychus, on the basis of the denticulation of chelicerae, which was often used in his catalogue (see Hirschmann 1993). The shape of the chelicerae is diverse within a genus, because modification of chelicerae is the result of an adaptation of feeding habits (Evans 1972), so its taxonomic value is questionable. For this reason, this difference is insufficient to justify the separation of these two groups.</p> <p>Some years later Hirschmann (1979) mentioned Macrodinychus as a “Ganggattung”, with Macrodinychus Berlese, 1917, Bregetovamacrodinychus Hirschmann, 1979, Loksamacrodinychus Hirschmann, 1979 and Baloghmacrodinychus Hirschmann, 1979 as “Stadiengattungen”. Although Hirschmann (1979) discussed these groups as subgenera of the genus Macrodinychus, in the same paper (on pages 69 and 70) he refers to Macrodinychus Berlese, 1917, Bregetovamacrodinychus Hirschmann, 1979, Loksamacrodinychus Hirschmann, 1979 and Baloghmacrodinychus Hirschmann, 1979 as genera as well. This subdivision was based on the shape of the peritreme, of which four types are known in the genus Macrodinychus (see the key).</p> <p>According to my assumption Macrodinychus is a Uropodina genus distributed worldwide and comprising four subgenera; accordingly I consider Macrodinychus Berlese, 1917, Bregetovamacrodinychus Hirschmann, 1979, Loksamacrodinychus Hirschmann, 1979 and Baloghmacrodinychus Hirschmann, 1979 as subgenera in the present work.</p> </div>	https://treatment.plazi.org/id/F25B87B2FFE9FFBE2AF5FBD75030FC22	Public Domain	No known copyright restrictions apply.

The holotype stored in alcohol and deposited in Natural History Museum Geneva (NHMG).</p> <p>Description</p> <p>Male.</p> <p>Length of idiosoma 1630 µm, width 950 µm (n = 1). Shape oblong, posterior margin rounded.</p> <p>Dorsal idiosoma (Figure 2A). Dorsal and marginal shields not fused anteriorly. Isolated pygidial shield present, with alveolar pattern and without setae. Two halfring-form cavities can be seen in the central region of dorsal shield. Margin of cavities covered by bulbiform setae. Crenellation can be found between marginal and dorsal shields. All dorsal and marginal setae bulbiform with short hairs on their margins (Figure 2 B). Dorsal shield bears alveolar ornamentation.</p> <p>Ventral idiosoma (Figure 2 C). Sternal and ventral shields bear large, alveolar ornamentation. Shape and situation of sternal setae as follows: St1 and St2 bulbiform and placed near the level of coxae II. St3 smooth, needle-like and inserted near the anterior margin of coxae II. St4 and St5 bulbiform, St4 placed near the posterior margin of coxae II, St5 near the anterior margin of coxae IV. All ventral setae bulbiform. Scabellum covered by tile-like pattern.</p> <p>Genital shield circular, without ornamentation.</p> <p>Stigmata situated between coxae II and III. Peritreme with several finger-like branches.</p> <p>Legs with serrated setae.</p> <p>Gnathosoma. Corniculi, internal malae, epistome, hypostomal setae and chelicerae not clearly visible (covered by coxae I).</p> <p>Female, nymphs and larvae are unknown.</p> <p>Etymology</p> <p>The name of the new species refers to the several extreme characters (bulbiform setae, dorsal cavities) that are unique in this family.</p> <p>Remark</p> <p>The dorsal cavities and dorsal and ventral setae are unique in this family.</p> <p>Notes</p> <p>Unfortunately the new species is known from a male holotype only and more collections are needed in the type locality.</p> <p>Key to the species</p> <p>1.
