Teasienna
Heydon, 2004
: 183
–184; type species:
T. eirene
Heydon, 2004
, by original designation and monotypy.
Diagnosis.
Female clava asymmetric due to large area of microsetation (100%) (
Figs 75
,
87
,
95
,
120
); male clava symmetric (100%) (
Figs 74
,
106
); propodeum with flange-like projections anteriorly partially concealing dorsellum, with median area smooth, and without plicae (100%) (
Figs 80
,
98
,
109
,
118
); lateral side of prothorax with visible whitish membranous area between posteroventral corner of pronotum and fore coxa, posteroventral corner of pronotum short, rounded (100%) (
Figs 79
,
89
,
108
,
117
); posterior margin of gena not carinate (100%); medial ventral margin of scape at least partly carinate (100%) (
Figs 75
,
87
,
113
); antenna inserted below middle of face (100%) (
Figs 75
,
84
,
93
,
103
,
113
); both mandibles with 3 teeth, inner mandibular tooth double (100%) (
Fig. 103
); posterior part of mesoscutellum conspicuously surpassing base of propodeum, with one median spine (100%) (
Figs 78
,
96
,
107
,
116
); marginal vein much shorter than stigmal vein (100%) (
Figs 81
,
90
,
99
, 110,119); notauli complete (100%) (
Figs 78
,
88
,
96
,
107
,
116
). Male: scape without any ventral protuberance (100%) (
Figs 74
,
106
).
Remarks.
Due to its very short marginal vein (
Figs 81
,
90
,
99
,
110
,
119
),
Teasienna
resembles certain
Eutrichosomatinae
such as
Manineura
Bouček
and
Collessina
Bouček
, but differs from both genera mostly in having the axillae not advanced, and by a different shape of the clypeus and antenna. For differences
between
Teasienna
and
Austroterobia
, see comments under the latter genus. Previously known only from one
Oriental
species, the distribution of the genus now extends to the
Afrotropical region
, where the species diversity seems much higher. The biology is unknown, but given the gastral structure, which is similar to that of
Austroterobia
, it is highly possible that the hosts are also scale insects.
