Type
species (by original designation):
Pseudognaptodon curticauda
Fischer, 1965
.
Williams (2004)
recognized two species groups (both without medio-posterior depression of mesoscutum); one group with distinctly impressed and curved episternal scrobe, antero-lateral grooves of third metasomal tergite distinct and setose part of ovipositor sheath 0.5–0.9 × as long as hind basitarsus (
P. omissus
group) and one without distinct scrobe (at most present as shallow depression), antero-lateral grooves of third metasomal tergite indistinct or absent and setose part of ovipositor sheath less than 0.5 × as long as hind basitarsus (
P. curticauda
group). Unfortunately, these characters were not mentioned in the descriptions by
Cirelli
et al.
(2002)
, but judging from the figured metasoma, only
P. murupe
Braga & Penteado-Dias, 2002
, belongs to the
P. omissus
group and the rest to the
P. curticauda
group. Another problem is the existence of two primary homonyms:
Pseudognaptodon striatus
Williams, 2004
(not
P. striatus
Braga & Penteado-Dias, 2002
), and here renamed
P. williamsi
van Achterberg
,
nom. n.
in honour of Daryl Williams for his excellent revision, and
P. carinatus
Williams, 2004
(not
P. carinatus
Cirelli & Penteado-Dias, 2002
) is here renamed into
P. carinatoides
van Achterberg
,
nom. n.
The only known non-American species,
Pseudognaptodon ruficeps
Belokobylskij, 1992
, from
Vietnam
, is an aberrant species because of its metasomal sculpture: the first–third metasomal tergites (except apical half of third tergite) are largely longitudinally striate or rugulose, and the basal area of the second tergite is only 0.05 × as long as second and third tergites combined, features not encountered in any of the 28 New World species (
Cirelli
et al.
2002
;
Williams 2004
). The new species from NW
China
(
Shaanxi
) fills a gap in the distribution but is very different from
P. ruficeps
. It only shares the extensively sculptured three basal metasomal tergites, but the sculpture itself is different. The genus is new for the Palaearctic region and the Chinese fauna, and it is only the second known species in the Old World.
