Leptomorphus papua
sp. n.
(
Figs 43–49
)
Holotype
male (
BMNH
):
Papua
New Guinea
:
Madang Prov.
, rain forest near
Biteta Village
,
iv. 1987
,
Malaise trap
(
C. J. H. Godfray
).
Antennae
and most of its legs lost, only right mid and hind tibiae and femora, as well as left hind tibia and femur present; wings torn, apices lost
.
Paratype
male (
HNHM
, genitalia prepared and kept in a plastic microvial with glycerol): same data. Antennae, wings and all legs lost, only left fore femur and right hind femur remained
.
Measurements (
holotype
): wing length:
5.1 mm
, head + thorax
1.75 mm
, abdomen
3.8 mm
.
Diagnostic characters. Prefrons ventrally with 2 (3) strong setae only. Metanotum partly yellow. Terminal section of Cu
1
less downcurved, M
3
about 1.2 times as long as terminal section of Cu
1
.
Male terminalia. Pregenital (8th) sternite (
Fig. 43
) strongly narrowing proximally, with 3 pairs of lateral setae only. Sternite 8 at about its basal 1/3 with a darker transverse thickening. Tergite 8 (
Fig. 44
) broader than long, cranial 2/5 bare, setae are not on extreme edge. Male genitalia with tergite 9 and gonocoxites fused into a tergo-gonocoxal complex, which is about as high as broad (see ratio on
Fig. 45
). Caudal process of the complex separated from the other parts but on a small section ventrally (
Figs 45, 48
). Caudal processes serrate, both apically and basally (
Figs 46, 48
). Medial process of gonocoxite simple, not double, dark processes observable. Gonostyli very small (
Fig. 45
), embraced deeply into the medial part of gonocoxites; gonostylus with one – rather blunt – apical process only. Gonostyli rather different in dorsal view and in the view of their broadest extension (
Fig. 47
, vs
Fig. 46
). Aedeagus (
Fig. 49
) long, apex blunt. Ejaculatory apodeme not sclerotised, membranous (
Fig. 49
). Base of aedeagus continued into a pair of blunt processes (? to replace ejaculatory apodeme).
Etymology. Named after
