Pristiphora
armata (Thomson, 1863)
Figs 16, 57, 193, 263
Nematus
crassicornis
Hartig, 1837: 204-205. Primary homonym of
Nematus crassicornis
Stephens, 1835 [=
Cladius (Cladius) pectinicornis
(Geoffroy, 1785)]. 3 ♀♀ and 13 ♂♂ possible syntypes belonging to
P. armata
and
P. leucopus
in ZSM, examined. Type locality: Germany according to the title of the publication.
Nematus armatus
Thomson, 1863: 619. Seven possible female syntypes belonging to
P. armata
and
P. leucopus
in MZLU, examined. Type locality: Bohus
Laen
(
Bohuslaen
), Stockholm, and
Skane
, Sweden. Note. Because of difficulties separating
P. armata
from
P. leucopus
(see
Prous et al. 2016
), we refrain from selecting a lectotype at this stage.
Nematus crataegi
Brischke, 1883b: pl. I(7), 6. Syntype(s) possibly destroyed (
Blank and Taeger 1998
). Type locality: not stated, but probably in former East Prussia (now Kaliningrad Oblast of Russia, or Poland). Synonymised with
P. crassicornis
by
Konow (1905)
.
Nematus
Fletcheri [sic!] Cameron, 1884: 26. Syntype(s) possibly in BMNH, not examined. Type locality: Worcester and Clydesdale, United Kingdom. Synonymised with
P. crassicornis
by
Konow (1905)
.
Nematus melanostomus
Zaddach in Brischke, 1884: 140-141. Holotype ♀ possibly destroyed (
Blank and Taeger 1998
). Type locality: Bautzen, Saxony, Germany. Synonymised with
P. crassicornis
by
Konow (1905)
.
Nematus ensicornis
Jacobs, 1884: XXIII. Syntype(s) ♀ possibly in IRSNB, not examined. Type locality: near Brussels, Belgium. Synonymised with
P. crassicornis
by
Konow (1905)
.
Nematus nigricollis
Cameron, 1885: 66. Syntype(s) possibly in BMNH, not examined. Type locality: Worcester, United Kingdom. Synonymised with
P. crassicornis
by
Konow (1905)
.
Similar species.
The most similar species is
P. leucopus
. Differences between these two species, which unfortunately are not very strong, were discussed by
Grearson and Liston (2012)
and
Prous et al. (2016)
.
Genetic data.
Based on COI barcode sequences,
P. armata
belongs to the same BIN cluster (BOLD:AAQ2302) as
P. leucopus
(Fig. 4). Maximum distance within the BIN is 2.41% and minimum between species distance is possibly 0.00%. The nearest neighbour to BOLD:AAQ2302, diverging by minimum of 2.76%, is BOLD:AAG3568 (
P. aphantoneura
,
P. bifida
,
P. confusa
,
P. luteipes
,
P. opaca
,
P. pusilla
,
P. staudingeri
, and
P. subopaca
). Based on nuclear TPI sequences,
P. armata
(one specimen) and
P. leucopus
(two specimens) cannot be separated either. The
P. armata
specimen is identical to one of the
P. leucopus
specimens when ambiguous positions due to heterozygosity are excluded.
Host plants.
Crataegus
species (Brischke 1883,
Grearson and Liston 2012
).
Distribution and material examined.
