Hypselothyrea brevipennis
DE
MEIJERE
, 1906
DE
MEIJERE
1906: 195
.
Material studied (
HNHM
):
holotype
female: double mounted through a 10×5×
1.2 mm
Sambucus-like
bricklet, minuten covered by and transferred into FeS (?Ag
2
S) crystals, the original hole of minuten
4 mm
deep, dark, the minuten was broken, the specimen repinned into bricklet behind the original hole; right wing on a white label pinned under the specimen, which is without head and abdomen, also hind legs lost and all setae broken
.
Labels
on
holotype
: 1) [printed card, 11×
4 mm
]
Sattelberg Huon Golf
[on reverse side] “IX. 25.”; 2) [printed card, 10×
4 mm
] N.
Guinea
,
Biró
1898, 3) [grey paper, 5×
4 mm
] “4” (a collection label of
Biró
or of the
HNHM
; an additional label between 3) and 4), printed number, 39, I think it as an identity label of
DE
MEIJERE
during his studies; 4) [dirty white paper, 20*
9 mm
, handwriting of
DE
MEIJERE
] “
Hypselothyrea brevipennis de Meij.
Type. de Meij. det.05.”; 5) [red margined
Holotypus
label of the
HNHM
, without writing]
.
Wing length
1.31 mm
, wing breadth
0.485 mm
.
Another, topotypic female was found in the
HNHM
(rusty needle, double mounted in a Sambucus-like bricklet of 12×9×
5 mm
with rusty minuten; specimen without head, left wing and left hind leg): labels 1) – 3) as on the
holotype
; the last one is obviously a collection label referring to the same locality as of the type, 4) [dirty white paper, 18×
10 mm
, handwriting of
DUDA
] “
Hypselothyrea brevipennis de Meij.
f d. Duda”, 5) [yellow paper, 15×
8 mm
, handwriting of
DUDA
] “l. Flügel photogr.”
.
There is a third pin in the
HNHM
, which is obviously a head of this species. Labels 1)–3) as above, 4) “
Hypselothyrea brevipennis
f det. Duda” (
DUDA’
s handwriting, i.e. labelled by
DUDA
, which emerges a mystery, since labels 1) and 2) were printed in
Budapest
).
The head may belong to any of the
two specimens
. This head is without setae and left antennae and glued massively on a plastic (celluloide) label. Right antenna with 6 dorsal and 3 ventral long aristal rays, frontal shield granulose. As a matter of course, I cannot decide whether the
holotype
specimen is a male or a female (cf.
BÄCHLI
1984
b
: 30
).
OKADA
(1980)
did not see the
type
of this species and some of its characters were erroneously given there. This is why I add some additional features here.
I was able to detect only the posterior pair of dorsocentrals. Mesonotum microgranulose, mat, dark graphite-grey. Scutellum comparatively small, upright. Legs not unicolorous, as stated by
OKADA
: fore coxa, basal half of fore femur, basal 3/5 of mid and hind femora, whole mid tibia, mid and hind tarsi yellow, fore tarsus (except for the dark base of metatarsus) whitish, apical half of fore femur, apical2/5ofmidandhindfemoraandforetibiadark;righttibiaofthesecondspecimen is brown. Wing patterned (see fig. 4 of
DUDA
(1928))
: dark brown with 3 light transverse bands consisting of 3 confluent light spots each, Cx 3.0 or so, 2.95 on
holotype
.
OKADA’
s (1980) key is improper to identify this species, which is otherwise a very distinct one.
