Notes. The main difference between Cosmolaelaps and Gaeolaelaps is the shape of dorsal shield setae. In Gaeolaelaps the setae are acicular, but in Cosmolaelaps they are variously flattened and may be possess a knoblike projection at their base (Gwiazdowicz et al., 2014). Dorsal and ventral figures of female and male along with the leg chaetotaxy of this species were presented by Lapina (1976). The dorsal setae have a knob at their base. In all examined specimens in Iran and Germany (see above) the dorsal shield setae possess a distinct knob at their base. According to the above examination and explanations G. angustiscutatus is transferred to Cosmolaelaps .
