Teasienna Heydon

( Figs 72–120 )

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.
