Introduction
A new genus and species of mycetophagous acarid mites (adults and hypopi) belonging to tribe Caloglyphini
was collected by the author in Ussuriyskiy Reserve (Russia, Primorskiy kray) and Siberia (Irkutsk oblast). The new
genus is closely related to the genus Sancassania Oudemans, 1916 differing mainly by proximal position and spini-
form shape of the setae ba (tarsi I-II) in adults as in the genus Rhizoglyphus Claparède, 1869 (Rhizoglyphinae,
Rhizoglyphini). Description of new genus is given below. The terms of body parts and chaeto- and solenidiotaxy of
legs are follow Griffiths (1970); nomenclature of idiosomal chaetotaxy is follows Griffiths et al. (1990). All meas-
urements are given in micrometers (μm).
Tribe Caloglyphini Oudemans, 1932
Caloglyphidae Oudemans, 1932 (fam., part.) (cited after Zachvatkin, 1941)
Caloglyphini: Zachvatkin, 1937: 174 (part.); Samšiňák, 1980: 204; Klimov, 1998: 3 (part.)
Acotyledonini Zachvatkin, 1941: 126; F. Türk, E. Türk, 1957: 87. Synonymized with Caloglyphini by
Samšiňák (1980)
Caloglyphus-group: Woodring, 1966: 98.
The tribe includes 8 genera and more than 90 species and is world-wide distributed
(except Antarctica).
Diagnos i s . Adults. Cuticle smooth. Dorsal idiosomal chaetotaxy complete. Idiosomal
setae (beside vi) smooth. ve short, near middle of lateral sides of propodosomal shield. aa
developed. Chelicera with one seta. Grandjean’s organ simple, without accessory part which
is fused with body.

glyphus Oudemans, 1932; Ctenocolletacarus Fain, 1984; Lowryacarus Fain, 1986; Neoacotyle-

New combinat ions . Since the genus Caloglyphus was sinonymyzed with Sancassania
by Samšiňák (1960) and the genus Acotyledon is treated here in the sense of Samšiňák, 1980,
new combinations are proposed for the following species: Carabidobius bartheli (F. Türk et
E. Türk, 1957), comb. n. (from Caloglyphus); Carabidobius bifurcatus (Mahunka, 1973),
comb. n. (from Caloglyphus); Carabidobius regleri (F. Türk et E. Türk, 1957), comb. n. (from
Caloglyphus); Cosmoglyphus distantsis (Ashfaq et Chaudhri, 1986), comb. n. (from Acotyle-
don); Cosmoglyphus falki (Sher et Ashfaq, 1986), comb. n. (from Acotyledon); Cosmoglyphus
haripuriensis (Ashfaq, Sher et Chaudhri, 1990), comb. n. (from Acotyledon); Cosmoglyphus
hyper (Ashfaq et Chaudhri, 1986), comb. n. (from Acotyledon); Cosmoglyphus infaustus (Ash-
faq et Chaudhri, 1986), comb. n. (from Acotyledon); Cosmoglyphus limbata (Mahunka, 1974),
comb. n. (from Acotyledon); Cosmoglyphus memphiticus (Sevastianov et Rady, 1991),
comb. n. (from Acotyledon); Cosmoglyphus moshtohorenis (Sevastianov et Rady, 1991),
comb. n. (from Acotyledon); Cosmoglyphus pytho (Ashfaq et Chaudhri, 1986), comb. n. (from
Acotyledon); Cosmoglyphus ruditas (Ashfaq et Chaudhri, 1986), comb. n. (from Acotyledon);
Cosmoglyphus stremma (Ashfaq et Chaudhri, 1986), comb. n. (from Acotyledon); Cosmogly-
phus tariqii (Ashfaq, Sher et Chaudhri, 1990), comb. n. (from Acotyledon); Cosmoglyphus
thosmos (Ashfaq et Chaudhri, 1986), comb. n. (from Acotyledon); Neoacotyledon sokolovi
(Zachvatkin, 1940), comb. n. (from Acotyledon).
The following key is based upon the papers by Ashfaq et al. (1990); Cunliffe (1964);
Fain (1984, 1986); Fain, Philips (1978); Lombert et al. (1982); Mahunka (1973, 1974);
Rupes (1967); Samšiňák (1960; 1961; 1966; 1980); Sevastianov, Rady (1991); Türk, Türk
(1957) and Zachvatkin (1937, 1941). Adults of Ctenocolletacarus were described by Fain,
Houston (1986).

P. B. Klimov 30
Hypopi . Gnathosoma elongate. Rostrum moderately developed. Idiosomal setae short,

fields II. Proximal ends of epimeres II near each other, parallel on comparatively long

Anal disk shifted from hind end of hysterosoma at distance less than its length. 4a transverse,
elongate. Chaetotaxy of tibia-genu I—IV represented by smooth spines or setae.
Diagnos i s . Mycetosancassania gen. n. is closely related to genus Sancassania (sensu
Samšiňák, 1960) but differs in follows (characters of Sancassania in parenthesis): 1) ba I—II
spiniform, placed in proximal part of tarsus near ω1 in all homeomorphic ontogenetic stages
(setiform or needle-like, placed paramedially on tarsus, distant from ω1); 2) proximal ends of
epimerites II near proximal ends of epimerae III in adults (distant from each other); 3)
bursa copulatrix of female dorsally with characteristic peripheral radial ornament (simple); 4)
epimeres II posteriorly sternum in hypopi straight, parallel and near each other (curved, not
parallel, distant); 5) conoids 4a narrow, transverse in hypopi (rounded or setiform). The new
genus resembles Rhizoglyphus Claparède, 1869 but differs in having of aa.
Etymology . Generic name is derived from Greek noun μυχησ (fungus) and Sancas-
sania (genus of Acaridae) with the reference to habitats and similarity of new genus.

Diagnos i s . See above under the description of genus. Poorly-described Sancassania
mycophagus (Mégnin, 1874) (non auct.) has spiniform ba likes M. grifolapholiotae but distant
from ω1 (near ω1 in M. grifolapholiotae). It is noteworthy that S. mycophagus inhabits fungi
(Mégnin, 1874, cited from Zachvatkin, 1941).
Etymology . Specific epithet is derived from generic names of host fungi (Grifola and
Pholiota).
Dis t r ibut ion . Russia: Irkutskaya oblast’ (Bratskiy rayon), Primorskiy kray
(Ussuriyskiy Reserve) – type locality.

A review of the tribe Caloglyphini ... 35
Var ia t ions . aa and ω1 lie on the same transverse level, or aa distally from ω1 in adults
and hypopi. ad2 in female placed anteriorly ps2, at the same level, or posteriorly.
Bio logy . Large colonies of new species have been found on fungi Grifola frondosa in
Primorskiy kray and in stems of several Pholiota sp. grown on soil in Siberia. Two hypopi
have been collected at base of stem of Pholiota sp. in Primorskiy kray and put to 40% KOH.
Two days later these hypopi were still alive and both successfully moult to teleonymphs. In
culture of M. grifolapholiotae sp. n. from the samples associated with Grifola frondosa were
reared drosophilid flies Drosophila funebris (Fabricius, 1787) (Diptera, Drosophilidae). The
examination of large number of these flies shown that the insects are not a host of the mites.
Inside one dead hypopus of the same culture three alive females of nematode Acrostichus sp.
(Nematoda, Diplogasteroididae) were found (slides in IBPV). Way of invasion is unknown.
