( Fig. 6 )

Malacoscylus humilis var. grisescens Gahan 1892: 271 ; Aurivillius 1923: 586 (cat.); Blackwelder 1946: 623 (checklist); Gilmour 1965: 633 (cat.).

Gahan (1892) described this subspecies based on a male and females, not only males as reported by Monné (2020) and Tavakilian and Chevillotte (2020). There is no doubt about this because we have a photograph of a female syntype, and Gahan (1892) also commented that “… in one female example of the var. grisescens the punctuation is almost as much concealed as in the present variety [ M. humilis var. flavescens ].”

We believe it is very probable that females of M. humilis flavescens and M. humilis grisescens are the same species. We did not see photographs of males of this subspecies. Accordingly, we do not know if they are Lamacoscylus humilis or another species [equal or not to males of M. humilis flavescens ].

See comments under S. fulvescens to understand the reasons for not designating a lectotype for this species, and about the status of this variety described by Gahan.
