Pachylaelaps quadricombinatus Gu, Huang & Li, 1991

Pachylaelaps quadricombinatus Gu, Huang & Li, 1991: 437 . Type locality: China.

Notes. The dorsal shield chaetotaxy, the structure and chaetotaxy of the ventral shields, the epistome, the tarsus II, and the sperm access system of this species are very similar to those of Pachylaelaps pectinifer (G. Canestrini, 1881) . These two species may be synonyms, but we cannot confirm that decision until the male of P. quadricombinatus is described.
