Ptenothrix beta
No problem -- I'm appreciative of all efforts to sort these guys out to species!
Do you think this one is Ptenothrix beta as well?

Ptenothrix cf. renateae
Family = Dicyrtomidae.
The well in focus left antennae reveals
1. the short pointed 4th antennal segment (typical for Dicyrtomidae)
2. the subsegmented apical part of the 3rd antennal segment (typical for Ptenothrix).
The dorsal pattern resembles that of P. renateae.
