DIAGNOSIS
— Characteristic for the new species is the typical prodorsal shield design (

Prodorsal shield

sc
) missing. Shield design of faint median lines, aproximate on anterior two thirds and farther apart on posterior third; faint admedian and submedian lines on anterior two thirds; a few lines laterally. Legs missing tibial I, genual II and femoral I and II setae.
