R e m a r k s on the type series of
Bracon marshalli
(after
PAPP 2000: 249
, partly modified): SZÉPLIGETI (1901: 270) described his species on the basis of female and male specimens (" "). The precise number of the
syntype
specimens and the locality name(s) were not indicated by him, i.e. the species has been described within the key and its detailed description was not presented in the traditional way. The species name "marshalli" was applied to the species "
Br. obscurator Marsh.
(non Nees)" (Szépligeti l.c.) or as a new name (nomen novum) for
B. obscurator Nees sensu
Marshall (1885: 45)
. This taxonomic procedure explains the omission of the description. At present
three male
specimens (male
lectotype
and
two male
paralectotypes
) of
B. marshalli
are housed in the Hungarian Natural History Museum, these
three males
belong unambiguously to the original
syntype
series, reliable female specimen(s) was (were) not found (further
two male
paralectotypes
are representing
B. atrator
NEES
, see also
PAPP 2004: 177
). The
three males
were collected by Szépligeti in the localities "Budapest Óbuda" (
15 April 1896
,
two males
) and "Ungvár" (since 1945 Uzhgorod,
Ukraine
: Podkarpaty,
one male
, its designation see subsequently); the locality labels were partly handwriting by Szépligeti, thus the
three specimens
in question are considered as authentic ones. Furthermore, the
three males
were placed under the name "
Bracon marshalli
SZÉPL.
" in the collection set up by SZÉPLIGETI himself and, consequently, I name-labelled them accordingly (in the years 1960ies Szépligeti’s original braconid collection was re-arranged by me). One male was designated as the
lectotype
and the
two males
as the
paralectotypes
, Hym. Typ. Nos 1340 (
lectotype
), 1341 and 11014 (
paralectotypes
) (
PAPP 2004: 177
). The latter male
paralectotype
(no. 11014) is herewith designated: (first label) "Ungvár" (with Szépligeti’s handwriting) / "Szépligeti" (printed); (second label with my handwriting) "Kárpátalja /
Ukraine
"; (third label) "
Bracon marshalli Szépl.
" (with my handwriting) / "det. Szépligeti" (printed); fourth label is the
paralectotype
card, fifth label is with the inventory number 11014.
The
three male
type specimens are in poor condition. The
lectotype
no. 1340: (1) micropinned; (2) left antenna deficient, i.e. with 12 antennomeres; (3) metasoma missing. The
paralectotype
no. 1341: (1) micropinned, (2) head, left fore wing, left fore leg and metasoma missing. The
paralectotype
no. 11014: (1) micropinned, pin pricked through left fore and right hind wings hence fore left wing medially somewhat damaged, (2) metasoma missing.
The female and male specimens, serving for the subsequent re-description, were selected scrupulously by me (and re-named by me as
B. marshalli
) from among the huge material accumulated in the Hungarian Natural History Museum and named mainly by routine identification as
B. obscurator
, a species very similar to
B. marshalli
.
