Mesozoic amber cockroaches are rare compared to sedimentary imprints and are only
known from Myanmar, Lebanon, France, Russia and USA. Perspicuus csincsii sp. n. from
the Late Cretaceous (Santonian) ajkaite amber of Hungary with very long cerci, cup-like
terminal palpomere of the maxillary palp and fully carinated legs, is clearly distinguished
from all other Vitisminae species by the unique, black forewing with small light-coloured
dots/stripes and the absence of pubescence on the wings (autapomorphies). The second
cockroach described from the ajkaite adds important data to the distribution pattern
of Vitisminae during the Late Cretaceous and further highlights the similarity of
the ajkaite and burmite biotas.
