Remarks

In 2018, I described Ptiliola semitaria from Angola and illustrated alongside the figure of the spermatheca a second figure of a spermatheca of a specimen with a reduced length of duct between the pump and chamber which I suggested might be P. semitaria ( Darby 2018) . The spermathecae of Ptiliola from Sarawak include examples of similar ducts ranging in length between the two seeming to confirm that only one species is present. It is also worth noting that this form of spermatheca is similar to that of the European P. brevicollis (Matthews, 1860) , but in that species the duct is shorter.

A figure of the spermatheca of the Sabah P. semitaria is included for reference ( Fig. 5G ) together with figures of the Sarawak insect ( Fig. 5 A–F).
