Dyscritobaeus bicolor
sp. n.
(
Figs 4–5
)
Material examined:
Holotype
male: “
MOZAMBIQUE
,
Maputo
,
May 1989
leg.
Mrs Angela
”.
The
left antenna, wings and legs are slide mounted in
Faure’s
medium.
Holotype
is deposited in the
Insect Collection of Portici Università Federico
II-Napoli,
Italy
.
Diagnosis:
Dysctritobaeus
bicolor
differs from all other
Dyscritobaeus
species
of the
orientalis
species-group in having a sculptured praeoccipital area.
Male body length:
1.2 mm
Colour: castaneous head and mesosoma; castaneous scutellum with ochraceous rim; wings and legs ochraceous; T1–T3 ochraceous with remaining tergites castaneous; A1–A2 ochraceous with remainder of antenna castaneous.
Head: HW:HL:HH:IOS:MS = 22:5.5:10:14:3.8; EH:EW = 9.5:7; mandibles bidentate; A2 shortest, A12 longest of flagellomeres, the latter weakly tapering towards apex; length of A5–A11 almost quadrate in shape, length more or less equal; central keel present, slightly shorter antennal scrobe; antennal scrobe smooth, frons except for reticulate narrow areas along inner orbit and ventral margin of anterior ocellus coarsely punctuate and granulose; cheeks with radiating sulci; interommatidial setae short.
Mesosoma: MW:ML = 24.2:24.6; scutellum subrectangular, slightly longer medially at the meson; dorsellum wide, weakly spined at the meson, hardly surpassing the apical rim of the scutellum, not sculptured above with its rim slightly sinuate and overlapping the propodeum at the middle. Mesoscutum has reticulate sculpture with scattered punctures; mesoscutellum sculpture similar to that of the mesoscutum; notaulus and median mesoscutal line not marked; posterior
¼
of mesoscutum weakly concave; the forewing has a reduced postmarginal vein. Hind wing with sparse setae. The vestiture of the head, mesoscutum and scutellum consists of sparse short hairs.
Figs 4–5.

sp. n.
m: 4 = forewing, 5 = hindwing
Metasoma: MTL:MTW = 25:23; lT1:lT2:lT3:lT4 = 5:7:5:4; The specillum is absent; T1 traversed by rather dense striae and punctuate among the elements; T2 for all its surface has sculpture like that on T1 and on T3 where the striae are rarer; T1–T4 each terminating into a smooth apical stripe.
Female: Unknown.
Biology: Unknown.
Etymology: The species name refers to the dichromatic body colouration.
Note: The
holotype
of
Dyscritobaeus bicolor
was mentioned as
Dyscritobaeus
sp.
