Cosmolaelaps subacutiscutus Bai & Wang, 2005 Cosmolaelaps subacutiscutus Bai & Wang, 2005: 26. Cosmolaelaps subacutiscutus .— Ren & Guo, 2008: 328; Kazemi & Rajaei, 2013: 80; Moreira et al ., 2014: 320; Moreira, 2014: 231. Hypoaspis ( Cosmolaelaps ) subacutiscutus .— Bai & Ma, 2012: 557. Notes. These two species have been reported from China (Teng, 1982; Bai & Wang, 2005) and Iran (Kavianpour et al ., 2011; Soleimani & Joharchi, 2012; Kazemi & Rajaei, 2013). There are apparent similarities between C . acutiscutus , C . subacutiscutus and C . angustiscutatus . Cosmolaelaps angustiscutatus is recognised by several characters including: scimitar-shaped setae on dorsal shield with distinct knob at their base; the presence of abrupt curvature at the level of seta Z 3 on the dorsal shield; and about eight to ten pairs of setae between genital and anal shields (Willmann, 1951; Lapina, 1976; Karg, 1993; Beaulieu, 2009; personal observation of Karg collection specimens, 2014: see above). The abrupt curvature at the level of Z 3 in the dorsal shield, the presence of unpaired dorsal setae, a small inward curve in the lateral margins of the sternal shield (this character was observed in specimens of C . angustiscutatus in Karg collection, Berlin) and the presence of ten pairs of setae between the genital and anal shields could be considered as the main diagnostic characters of C . acutiscutus and C . subacutiscutus (Teng, 1982; Bai & Wang, 2005). Bai & Ma (2012) separated these species only based on dorsal setae length, which are slightly longer in C . subacutiscutus . Except for the unpaired dorsal setae, these characters could be observed in C . angustiscutatus . Our observation of C . brevipedestra as well as other studies such as Strong & Halliday (1994), Faraji & Halliday (2009) and Beaulieu (2009) have shown that the unpaired setae have no taxonomic value for separating species of Gaeolaelaps and Cosmolaelaps . By comparing the descriptions and figures of these species we could find no distinguishing authentic morphological differences, therefore, C . acutiscutus and C . subacutiscutus are suspected to be junior synonyms of C . angustiscutatus . : Published as part of Nemati, Alireza & Gwiazdowicz, Dariusz J., 2016, Description of a new species of Cosmolaelaps Berlese and the male of C. brevipedestra (Karg) from Iran, with notes on some other species of Cosmolaelaps Berlese (Acari: Laelapidae), pp. 535-551 in Zootaxa 4066 (5) on page 545, DOI: 10.11646/zootaxa.4066.5.2, http://zenodo.org/record/270562 : {"references": ["Ren, T.
