Description

21. Gaeolaelaps debilis (Ma, 1996) (Fig. 21)

ƞġșṻṄ응j (ṵAE)

Hypoaspis debilis Ma, 1996.

Hypoaspis debilis Ma, 2004.

Gaeolaelaps debilis Beaulieu, 2009, Yan et al., 2018: 261.

Material examined. Taehwa River (35°53′83″N, 129°31′ 13″E), Ulsan-si, Korea; Soil; collected by SY Keum on 3 June 2015.

Deposition. NIBRIV0000835092.

World distribution. China, Iran, Russia far east and Korea.

Diagnosis. Body size much larger (539 - 575 long, 288 - 315 wide) and leg I shorter than idiosoma, anal shield longer than wide, post-stigmatic section well developed after stigma. Presternal area sclerotized, with lineate reticulation and bearing st1. Sternal shield with almost smooth, with two pairs of simple and subequal sternal setae, st1 off the shield, genito-ventral shield narrower and longer, its posterior end reaches to the level of JV2, anal shield longer than wide and the peritreme extended to the middle of coxa I.

Remarks. This species is associated with nests of squirrel or ants, and phoretic but not parasitic. This can be free-living predators of smaller arthropods (Kafi et al., 2020). Gaeolaelaps debilis has the unusual character state of setae st1 off sternal shield. Sternal shield in Gaeolaelaps usually bears three pairs of setae, rarely setae st1 off shield in the presternal region. This only occurs in eight species of Gaeolaelaps (Beaulieu, 2009; Kazemi et al., 2014; Joharchi et al., 2019a - c). However, seta st1 being off the sternal shield in the presternal region can be difficult to discern. In particular, in some of the aforementioned species, seta st1 could be borne on paired anterior extensions of the shield, as in G. jondishapouri.

Family Pachylaelapidae Berlese, 1913 ĩ÷응jň

Genus Onchodellus Masan and Halliday, 2014

ǖĩ÷응jṧ

Material examined. Uiseong-gun (36°27′29″N, 128°23′ 36″E), Korea; collected by SY Keum on 23 April 2012.

Deposition. N. A.

World distribution. Japan and Korea.

Diagnosis. Dorsum. Dorsal shield entire, weakly reticulated, 30 pairs of simple setae. Setae i4 as long as the distance between bases of setae j4 and z2. Tritosternum well developed. Sternal shield fused with four pair of simple setae and five pair of pores. Genito-ventral shield wider than long. Peritreme extending anteriorly beyond coxae I and base of seta r1. Epistome median denticulate bifurcate process. Corniculi short. Tarsus II with a short stout spur.

Remarks. The species is bigger (length: 0.65 mm) than Pachylaelaps ishizuchiensis and was regrouped from the genus Pachylaelaps to the genus Onchodellus by Masan and Halliday (2014).
