Cephennium corruptum
group
Species of small size (
0.9–1.2 mm
), slender habitus, relatively long elytra, and pale colouration (usually reddish-yellow). Eyes composed of 3–5, sometimes weakly defined ommatidia without, or with very weak, pigmentation. Punctation of pronotum often more distinct than that of elytra. Elytra each with a small circular or transversely oval impression with whitish tomentose pubescence anteriorly. Hind wings completely reduced.
: protibia without distinct modifications; metaventrite extensively and shallowly impressed, depressed, or unmodified; aedeagus strongly dorso-ventrally depressed and short, much less than twice as long as broad; ventral process short and broad, apically broadly truncate; internal structures weakly to moderately sclerotized, not conspicuously minute, apico-medially with a more or less transverse structure; parameres thin, apically extending to, nearly to, or beyond apex of median lobe, with short and fine apical seta.
The species of the
C. corruptum
group can be assigned to two subgroups, one of them (
C. unguicum
subgroup) including five species (
C. unguicum
,
C. deplectens
,
C. sicaferum
,
C. geminum
,
C. duplum
) from Southwest
Anatolia
and characterized by the presence of pairs of large spines in the internal sac of the aedeagus. The
C. corruptum
subgroup, which comprises the remaining ten species, is distributed in central southern
Anatolia
,
Lebanon
, and
Jordan
and lacks such distinct spines.
In the study region, the representatives of the
C. corruptum
group are locally endemic in South and Southwest
Turkey
(thirteen species),
Lebanon
(one), and
Jordan
(one) (
