Cryptophleps
Lichtwardt
Cryptophleps
Lichtwardt, 1898: 491
.
Type
species:
Cryptophleps kerteszi
Lichtwardt, 1898
(monotypy).
Etymology
. From Greek:
kryptós, phléps
(with hidden veins); gender feminine.
Diagnosis
. This genus is defined (together with cosmopolitan
Asyndetus
Loew, 1869
) by the synapomorphy of the broken and displaced vein M which readily distinguishes both genera from the related and probably ancestral cosmopolitan genus
Diaphorus
Meigen, 1824
. Small species, body length
1.1–2.5 mm
; body with bristles yellow (Afrotropical and some Palaearctic species), sometimes partly black or almost entirely black (Australasian and
Seychelles
species); face broad (
C. kerteszi
and Afrotropical species), moderately broad (
Seychelles
species) or linear (Australasian species); costa not extending beyond tip of R4+5; distal vein M gently sinuate or broken or weakened, with distal section often displaced; vein R4+5 ending along distal anterior wing margin, well before wing apex; distal parts of R4+5 and M1+2 strongly diverging; acrostichals absent or microscopic; usually 4 strong dorsocentral setae present; male segment 8 with or without strong setae.
Remarks
. A thorough re-description of all the characters can be found in
Grootaert & Meuffels (1987)
and
Bickel (2005)
, which was based mainly on Australasian species.
