Tadaxa Nye
Type
species: bijungens Walker,
Sri Lanka.
Synonym: Daxata
Walker
(type species bijungens) praeocc.
This
genus consists of two species about the same size as those of Maguda,
and with somewhat similar facies. However, the labial palps are longer, slender,
upcurved, the curvature being in the second segment. The male antennae are
fasciculate or ciliate. The second abdominal tergite lacks phragma lobes.
In the
male abdomen, the eighth sternite is of the framed, corematous type, the pair of
coremata well developed and the frame narrow but strong along the anterior
margin and part of the lateral ones. The sclerotisation of the tergite is
narrow, an elongate triangle broadening distad. In the genitalia, the uncus is
dorsally peaked in the type species but simple in the Bornean species. The
tegumen extends slightly below the junction with the vinculum on each side. The
valves are narrow, without processes, though the ventral and apical area is
invested with numerous dorsally directed setae. There is a transtilla. The
aedeagus vesica is invested generally with coarse scobination.
The
female of the type species has the ostium between the seventh and eighth
segments. The ductus arises narrowly from it, unsclerotised, and expands gently
into a rather elongate, pyriform bursa, slightly corrugated throughout.
The
genus, despite its similarity in appearance to Maguda,
lacks boletobiine features and should be excluded from that group.
