Diagnosis Deutonymph: The idiosoma length is 521­985 μm. The podonotal shield is well sclerotized, granular and entriely reticulated. It bears 21 pairs of setae of z 1, s 1 and s 2 are very short and peglike. The remain setae are stout and of varying lenghts with z 5 and r 3 the longest. The opisthonotal shield is of similar texture to the podonotal shield. It bears 13 pairs of homogeneous setae of variable lenght which have traces of pilosity at their tips. The posterior membrane bears short setae. The endopodal shields are generally darkly sclerotized, especially at coxae IV. The opisthogastric setae are fine and simple the anal shield is elliptical, reticulated and granular, and the paranal setae are slender, the postanal stouter. The peritreme extends to coxa I. The tectum comprises a sharply tapered central prong flanked a pair of inwardly curved side prongs ( Fig. 2 ). The chaetotaxy of the palp trochanter, femur and genu is as in Fig. 2 , with the anterolateral setae on the femur and genu alike, broadly spatulate distally, whilst the distal dorsal seta on the femur is noticeably stout and finely pilose in its distal half ( Fig. 2 ).

Material examined. Total 26 deutonymphs. This species were found en mass from the carrion beetles of the genus Nicrophorus ( Silphidae ) as in the deutonymphal stage of phoretic interaction during autumn season. Information of sampling and habitats are detailed in Tables 2 and 3 .

Voucher specimen deposition. NIBR No. NIBRIV 0000325954.

Distribution: England, Wales, Scotland ( Hyatt, 1980), Japan, Europe, Russia, China, USA ( Takaku et al., 1994), GB, Korea (this study).
