Seta v’ present on genua I and II. Immatures: Unknown. Etymology. This species is named in honour of the eminent acarologist, Professor Dr. Reinhart Schuster. Remarks. Both males and females of this species are easily recognized by the capitate bothridial seta, short notogastral setae, and apophyses posteriorly on the prodorsum expressed as 1 pair of discrete tubercles overhanging the dorsosejugal scissure. Sexual dimorphism in this species consists of males with posteromedial weakly porose cavity, about 20 width, positioned between lyrifissures ips, bearing setae h 1 and p 1 internally in cavity. Setae h 1 and p 1 thick, strongly modified from that of female, with tendril-like barbs. Gravid females carry up to 2 large eggs. Gut contents are primarily darkly pigmented fungal hyphae and spores.

Scale bar: 42 –45, 47 = 20, 46 = 10. Sexual dimorphism in Autogneta. Most oribatid mites exhibit slight sexual dimorphism in size, but strong dimorphism is uncommon (Behan-Pelletier & Eamer 2010). In Autognetidae it was previously known only in Cosmogneta impedita and Cosmogneta kargi, which show a modified seta a’ on tarsus I (Grandjean 1960 b, 1963, respectively), and an unidentified Autogneta species from Madeira which has thickening of the integument in the humeral region of the notogaster (Travé 1959). Herein I have shown that dimorphism also exists in other species of Autogneta, including the rather well-known type species, A. longilamellata and that it takes a form that is novel in the family. In Autogneta amnica, A. longilamellata and the 3 Autogneta species described above, sexual dimorphism is expressed as a porose region posteriorly on the notogaster in males. Although I have no direct evidence, the restriction of this porose region to the male suggests that these are secretory structures, secreting semiochemicals to enhance associative mating in these species, or to facilitate location of spermatophores by females, by marks on the substrate. A function of cuticular maintenance is also possible, as “behavior of adult males of dimorphic species may require greater production of maintenance materials” (Norton & Alberti 1997), though as these authors noted, it is less likely than that these are secreting semiochemicals. These porose regions are present despite these Autogneta species not expressing the octotaxic system of porose areas. In this they are not unique, as other non-poronotic Brachypylina, express sexual dimorphism involving porose regions. In the amerobelbid (Ameroidea) Hellenamerus ionicus Mahunka, 1974, porose regions are found on the ventral plate of males only (Behan-Pelletier & Eamer 2010). In Fortuyniidae (Ameronothroidea) males only of Fortuynia atlantica Krisper & Schuster, 2008 have 4 pairs of porose regions on the notogaster, along with modifications of notogastral shape and some notogastral setae. These expressions of sexual dimorphism and those in species of Autogneta, described above, confirm that porose organs with a possible secretory function, that apparently occur independent of the octotaxic system, can express sexual dimorphism. For example, possibly secretory porose organs are found on anal plates in males only of the zetomimid Heterozetes aquaticus (Banks, 1895), and on the ventral plate in males only of H. minnesotensis (Ewing, 1913), species in which the octotaxic system is absent, presumably lost, as it is expressed in the con-familial genus Zetomimus Hull, 1916 (Behan- Pelletier & Eamer 2003). The close association of setae, often modified, with these sexually dimorphic porose regions, as is found in Autogneta flaheyi, A. schusteri, and A. amnica, suggests that these setae may contribute in some as yet undefined way to the dispersal of semiochemicals (Norton & Alberti 1997). Species of Autogneta expressing sexual dimorphism are associated with habitats that are spatially discrete, e.g., decaying wood and fungi (A. aokii, A. flaheyi, A. longilamellata, A. amnica) and ferns (A. amnica); they are rarely found in general forest litter. Norton and Alberti (1997) noted that sexually dimorphic species generally inhabit non-soil microhabitats. This possibly explains why A. longilamellata, a species with a Palearctic and Nearctic distribution, is rarely encountered in ecological studies on soil microarthropods, and has been recorded primarily from decaying wood habitats, such as tree hollows (Taylor & Ranius 2014), fallen logs (Skubała & Marzec 2013), tree stumps (Skubała 2008), and decaying fungi on trees (Maraun et al. 2014).Published as part of Behan-Pelletier, Valerie M., 2015, Sexual dimorphism in Autogneta, with description of three new species from North America and new diagnosis of the genus (Acari, Oribatida, Autognetidae), pp. 55-78 in Zootaxa 3946 (1) on pages 71-75, DOI: 10.11646/zootaxa.3946.1.2, http://zenodo.org/record/28831
