Remarks
. Delucchi described both sexes and stated`Type deÂpose au MuseÂum d’Histoire Naturelle de
Vienne
.’ but did not specify the number of specimens he had. The identity of the type series was di cult to establish, since`Stuhleck am Wechsel,
Steiermark
(
Austria
), leg. R. Hicker’ (1955a: 29) was cited as origin of the material. However, from the description and the identi®cation labels it is evident that the specimens listed above represent original material. The
holotype
clearly served Delucchi for the description of the female except that the measurements given for the female veins were probably taken from the slide mounted fore wing (of a male, but see below). Furthermore, the correct association of the slide mounted parts was challenging. First, close examination and measurements revealed that the shorter of the two antennae of the one slide originates from the
holotype
. The other apparently belongs to the
paratype
female from
Austria
. Second, the left fore wing of the other slide can not stem from the
holotype
, as might be supposed from the indication`ala m’ on the label, because it has retained the humeral plate on the left side whereas the wing on the slide is entire. As judged from measurements the slide undoubtedly belongs to the
paratype
male in the NMW.
In his key (1955a: 22) Delucchi distinguished the female of
glaucum
from that of
Lamprotatus novickyi
(Delucchi)
[sub
Skeloceras
] based on the seventh funicular segment being only slightly longer than broad (more than 1.5 times in
novickyi
), the cubital fold of the fore wing glabrous on both sides (hairy on lower side), the median area of the propodeum without a costula and reticulate (with a costula and lustrous). Re-examination of the name-bearing types alone showed that these characters are critical for separating the species. The cubital fold of the
holotype
of
glaucum
has six hairs proximally and another six before its conjunction with the basal fold on the lower surface (eight respectively ®ve in the
holotype
of
novickyi
). An irregular but distinct costula is also present in the
holotype
of
glaucum
. Interestingly, Delucchi also refers to this feature in his description of the female (1955a: 28), thus contradicting his key. What remains is the length of the seventh funicular segment and the sculpture of the median area of propodeum where the specimens indeed diOEer as mentioned above. Examination of
27 females
and
37 males
from Central and Northern Europe (BMNH, MG, MHNG, MZL, VD, ZB) showed that these small diOEerences represent variation of a single species only. Moreover, both the female and male
paratypes
of
glaucum
run to
novickyi
in Graham’s key (1969: 242, 243), too. It should be noted, however, that the latter author most probably inferred the characters of the male of
glaucum
from Delucchi’s ®gure of the false`male’ antenna (see above) as he had not seen the type series or any fresh material of that species (
Graham, 1969: 246
).
