No full textGenus Tachornithoglyphus gen. nov. Type species: Guatemalichus tachornis Cruz, Cuervo and Dusbabek, 1984 Guatemalichus non Fain and Wharton, 1970: Cruz et al. 1984: 1 (part.); Cruz 1988: 14 (part.); Fain 1988: 22 (part.); Fain 1990: 22 (part.) Description. BOTH SEXES: Full set of idiosomal and leg setae and solenidia, except for famulus ε absent. Setae si situated very close and slightly anterior to bases of setae se. Setae h 2 and h 3 whip-like. Central sclerite of ambulacral disc with anterior portion, shaped as narrow wedge. Dorso-apical spur of tarsi I and II present. Apices of tarsi III and IV without spurs. Setae s III, w III, r IV slightly thickened, spine-like. MALE: In homeomorphic male, setae c 2 situated off humeral shields; in heteromorphic males c 2 situated on humeral shields. Coxal apodemes Ia fused to form a Y-shaped structure in heteromorphic males and intermediate forms and contiguous in homeomorphic males. Adanal shields distinctly developed and fused to each other. Tarsus I with ventro-apical antiaxial spur; tarsus II without this spur. Sucker-like setae d IV and e IV widely separated from each other. In heteromorphic male, femora and genua of legs I widened, femora with 2 ventro-lateral triangular projections. Setae e III and f III filiform. Legs III about 1.4 times longer than legs IV. FEMALE: Setae c 2 situated off humeral shields. Hysteronotal shield present. Lateral parts of epigynal arch contiguous to coxal apodemes Ia. Posterior lip of ovipore triangular, longitudinally striated, without apical incision and sclerotization,. Setae 4 a situated distinctly posterior to level of bases of setae g. Basal cup of bursa copulatrix indistinct. Setae e III–IV and f III–IV filiform. Differential diagnosis. Diagnostic characters of the new genus are listed in Table 1; details of the female of Guatemalichus bananae are in Fig. 1. The new genus differs from the other four genera of the subfamily Guatemalichinae in having solenidion σ 1 of genu I three or more times shorter than the segment (vs. solenidion σ 1 I is at least half as long as genu I), by the absence of famulus ε of tarsus I (vs. present), and by coxal apodemes Ia contiguous to the lateral parts of the epigynal arch (vs. posterior tips of apodemes Ia fused to each other and with the median part of the epigynal arch, or separated and contiguous to or fused with the median part of the epigynal arch). See Table 1 (column IV) for state distributions of the latter character in the guatemalichine genera.

Heideman). Data on localization of mites on A. lamellatus was not reported. Host specimen in the University of Michigan Museum of Zoology (UMMZ) bearing the voucher label, “Mites removed, B.M. OConnor #83-1800-024.” The host specimen was collected in a decaying log in primary dipterocarp forest. Type deposition — The holotype and one paratype are deposited in the collection of the University of Michigan Museum of Zoology, Ann Arbor, MI, USA; one paratype is deposited in the collection of the Tyumen State University Museum of Zoology, Tyumen, Russia. All specimens are stored in ethanol with a drop of glycerol. Note: Roman letters refer to normal setae, Greek letters to solenidia (except ɛ = famulus). Single prime (’) indicates setae on anterior and double prime (”) setae on posterior side of the given leg segment. Parentheses refer to a pair of setae. Etymology — The species name paracuriosus refers to the similarity between the new species and Perscheloribates curiosus Ermilov, 2016. Remarks — In the presence of a pointed rostrum, lanceolate bothridial head and developed notogastral setae, and in the absence of prolamella, the new species is similar to Perscheloribates curiosus Ermilov, 2016 from Cuba (see Ermilov & Tolstikov 2016), but differs from the latter by the morphological differentiation of the notogastral setae c, (la, lm short, simple; others distinctly longer, flexible) (versus all setae short, similar in length, simple in P. curiosus), the presence of flexible anal and adanal setae (versus simple in P. curiosus) and a keel-shaped ridge on the lateral side of the prodorsum (versus absent in P. curiosus), and the absence of custodium (versus present in P. curiosus).Published as part of Ermilov, Sergey G. & OConnor, Barry M., 2020, New Perscheloribates species (Acari, Oribatida, Scheloribatidae) phoretic on beetles (Insecta, Coleoptera), pp. 289-300 in Acarologia 60 (2) on pages 290-295, DOI: 10.24349/acarologia/20204368, http://zenodo.org/record/448776

Material examined — Holotype (female) and three paratypes (one male and two females): U.S.A., Michigan, Emmet Co., Wilderness State Park, 45°44’N, 84°55’W, phoretic on specimens of Phellopsis obcordata (Kirby, 1873) (Coleoptera, Zopheridae), May 1981 (J. Kukor). Host specimen in UMMZ bearing the voucher label, “Mites removed, B.M. OConnor #81-0604-001.” Mites were found on 3 specimens of P. obcordata collected from a fruting body of the polypore fungus, Porodaedalea pini (Brot.) Murrill, 1905 (= Fomes pini, = Phellinus pini), growing on red pine, Pinus resinosa Alton, 1789. Mites were found in pits on the dorsal surface of the elytra. The habitat consists of around 4050 hectares of dense coniferous and mixed hardwood forest on the northeast shore of Lake Michigan. The host beetle is associated with several species of polypore fungi in dense boreal forests in Eastern North America (Evans 2014), suggesting that the normal habitat of this mite species is either on or in the fungal fruiting bodies or in the mycelium growing within the wood of the host tree. Type deposition — The holotype and two paratypes are deposited in the collection of the University of Michigan Museum of Zoology, Ann Arbor, MI, USA; one paratype is deposited in the collection of the Tyumen State University Museum of Zoology, Tyumen, Russia. All specimens are stored in ethanol with a drop of glycerol. Note: See Table 1 for explanation. Etymology — The species name parakontumensis refers to the similarity between the new species and Perscheloribates kontumensis Ermilov & Frolov, 2019. Remarks — In the presence of pointed rostrum, lanceolate bothridial head with long setiform apex and developed notogastral setae, and in the absence of prolamella, the new species is similar to Perscheloribates kontumensis Ermilov & Frolov, 2019 from Vietnam (see Ermilov & Frolov 2019a), but differs from the latter by the presence of simple notogastral setae (versus with flexible tip in P. kontumensis) and the absence of body sculpturing (versus simple in P. kontumensis) and setae it on leg tarsi I–III (versus absent in P. kontumensis). General remarks As previously noted (Norton 1980; Ermilov 2019; Ermilov & Frolov 2019a, b), some oribatid mites are actively phoretic on insects, having morphological adaptations for attachment to the host (for example, gripping setae of beetles between the rostrum of the aspis and the anterior portion of the genital plates in ptyctimous mites, or specifically curved leg claws for holding onto setae of the host as in Siculobata (Paraleius)) (Norton 1980). However, other oribatid species (including P. paracuriosus n. sp. and P. parakontumensis n. sp.) have no visible adaptations, so mostly hold the host’s surface by hiding in various depressions and grooves of the host body and using the force of the pretarsal claws for attaching to the surface. Beetles of the family Passalidae are one of the more common insect hosts actively used by oribatid mites for phoresy (Ermilov 2019), however, phoretic oribatid mites had not been previously reported from A. lamellatus, nor from any beetles of the family Zopheridae. Hence, our findings (P. paracuriosus n. sp. on A. lamellatus and P. parakontumensis n. sp. on P. obcordata) are the first records of the use of A. lamellatus and zopherid beetles by oribatid mites for phoresy.Published as part of Ermilov, Sergey G. & OConnor, Barry M., 2020, New Perscheloribates species (Acari, Oribatida, Scheloribatidae) phoretic on beetles (Insecta, Coleoptera), pp. 289-300 in Acarologia 60 (2) on pages 295-299, DOI: 10.24349/acarologia/20204368, http://zenodo.org/record/448776
