Notes
Wiśniewski and Hirschmann (1993) did not place this species into any of species groups; on the basis of the shape of the peritreme (U-shaped) it is moved into subgenus Monomacrodinychus .

Material examined
One female, on the slide “45-2e” ( HNHM).
Remarks
Hirschmann (1975a) mentioned only the shape of the central region of the peritreme as a distinguishing character between M. parallelepipedus and M. paraguayensis , (the central region of the peritreme in M. paraguayensis turns anteriorly, but this character is missing in M. parallelepipedus ). This slight difference is insufficient for justifying separation of a new species, therefore M. paraguayensis should not be regarded else than a junior synonym name of M. parallelepipedus .
New records
One female: Suriname, ( Suriname 1521) Mites on Passalus species, 1932 leg.G. Bunzli. ( NHM, London).
Distribution

Macrodinychus (Macrodinychus) malayicus sp.nov.
Material examined
Holotype: male. Leaf litter and soil under jungle trees, Kuala Lumpur Peninsular, Malaysia, 21 September 1980. leg. J.D. George. Paratype: one male, locality and date same as holotype. Holotype and paratype are stored in alcohol and deposited in the Natural History Museum, London.
Description
Male. Length of idiosoma 840–850 µm, width 540–550 µm (n = 2). Shape oblong, posterior margin rounded.
Dorsal idiosoma ( Figure 1A View Figure 1 ). Dorsal and marginal shields not fused anteriorly. Isolated pygidial shield present with smooth surface and bears two pairs of pilose setae. Dorsal setae with short hairs on their margins, and placed in small alveolar cavities ( Figure 1B View Figure 1 ). Crenellation can be found between the marginal and dorsal shields on the central and posterior regions. Marginal setae in these regions without small, alveolar cavities. These cavities bear pilose setae and they are only present on the anterior region of marginal shield.
Ventral idiosoma ( Figure 1C View Figure 1 ). Sternal and ventral shields covered by small, alveolar cavities, these cavities bear setae with short hairs on their margins ( Figure 1D View Figure 1 ). Several small alveolar ornamentations can be found near the metapodal line.
Genital shield circular, with small alveolar ornamentation.
Stigmata situated between coxae II and III. Peritremes wide and U-shaped.
Legs with serrated setae.
Gnathosoma. Corniculi, internal malae, epistome, hypostomal setae and 210 chelicerae not clearly visible (covered by coxae I).
Female, nymphs and larvae are unknown.
Etymology
The name of the new species refers to the country ( Malaysia) where the species was collected.
Remark
The small alveolar cavities on the dorsal, ventral and sternal shields distinguish the new species from all the others in this subgenus.
Notes
Unfortunately the new species is known from two males only and more collections are needed in the type locality.
