Synonymie : Litman et al. 2021 : "Costa described Stelis leucostoma from Sardinia
(Costa, 1883). Warncke (1980), Rasmont et al. (1995),
Přidal (2004) and Ornosa et al. (2008) each placed
S. leucostoma in synonymy with P. nanum (as
either Anthidium lituratum or Pseuodanthidium
lituratum). However, Nobile (1995) considered
this taxon a distinct species. Nobile noted that his
decision to assign this name to this particular taxon
was based on Costa’s original description of Stelis
leucostoma but he gives no indication of having
examined the type series. Nobile illustrated the
male gonostylus and sterna of a specimen collected
close to Nuoro (Sardinia); this specimen, as well as others that we have examined from Sardinia, agree
with our concept of P. stigmaticorne. At the present
time we place Stelis leucostoma in synonymy with
P. stigmaticorne. However, both P. stigmaticorne
and P. nanum are known from Sardinia, and Costa’s
description of Stelis leucostoma is suggestive of
both. Costa’s type series must thus be examined to
determine whether the name Stelis leucostoma refers
to the taxon that we refer to as P. stigmaticorne or to
another."
