Nothing is known of the biology of any of the four species here recognised in this genus, but each is presumed to be leaf-feeding. The genus does not seem to be related to any other Australian
Panchaetothripinae
, although it is closely related to a monobasic
New Zealand
genus,
Sigmothrips
. This has been found living on the seedlings of several unrelated plants in
New Zealand
(
Mound & Walker, 1982
), and
Bhattithrips
species possibly have a similar host association.
S. aoteroana
differs from the species of
Bhattithrips
in having swollen cheeks and elongate setae on the ninth abdominal tergite (
Ward, 1970
), but the relationships of these two genera to other
Panchaetothripinae
are not clear. The two share with
Astrothrips
the presence on tergite II of specialised areas of sculpture that comprise broadly based and strongly curved microtrichia. However, in
Astrothrips
species these areas are anterolateral on tergite II, but in
Bhattithrips
(
Fig. 10
) and
Sigmothrips
they are sub-median. The most probable relatives to these two antipodean genera are members of the Neotropical genus
Dinurothrips
(
Mound et al., 2001
)
. Character states used previously in identification keys to
Bhattithrips
species (
Mound, 1970
;
Wilson, 1975
) have been found to be variable, but the sculpture of tergites II–IV is characteristic in each of the four species.
