sp. n.
(
Figs 6, 7h, 8
)
Material
examined:
Holotype
female: “
MOZAMBIQUE
,
Maputo
,
May 1989
leg.
Mrs Angela
”;
The
right forewing and hindwing are slide mounted in
Faure’s
medium.
Paratypes
2 females
same data as the holotype.
Holotype
is deposited in the
Insect Collection of Portici Università Federico
II-Napoli, Italy;
paratypes
are deposited in
National Museum of Ireland
and G.
MINEO
personal collection
.
Diagnosis:
Dyscritobaeus hannibal
shares with
D. orientalis
the circular and posteriorly located specillum and the subequal length of the postmarginal and the stigmal veins.
D. hannibal
, however, differs from
D. orientalis
in the smaller magnitude of the angle between these two veins (30 degrees in
D. hannibal
and 50 degrees in
D. orientalis
(
Figs 7o, 7h
), the broader forewing, shorter setae on the posterior forewing margin (
Figs 6, 9
) and the coloration of A7–A12 (
D. hannibal
golden-yellow;
D. orientalis
black).
Female body length:
1.4 mm
.
Colour: Mesosoma, metasoma and A7–A12 brown; head dark brown; A3–A6, coxae light brown; A1, A2 and legs excluding coxae golden-yellow; tegula light-yellow.
Head: Distance between lateral ocellus and praeoccipital carina is shorter than diameter of ocellus; Surface of the frons very minutely granulose from the scrobe out.
Mesosoma: MW:ML = 28:33; while the sculpture of the mesoscutum and scutellum consists of minute reticulation that is covered with a dense and short vestiture; forewings, see figs 7, 8h & 9. Posterior ¼ of mesoscutum weakly concave.
Metasoma: MTW:MTL = 20:28; MTL shorter than head+mesosoma; T1 crossed by dense and fine costae which are percurrent; the surface of T2 reticulate and transversed by dense and weak costae rather convergent to the specillum; remaining tergites with a minutely reticulate sculpture.
Male: Unknown.
Biology: Unknown.
Etymology:
Dyscritobaeus hannibal
is named after Hannibal, the famous Carthaginian military commander.
