Kenyattathrips katarinae
sp.n.
Female macroptera
. Body bicoloured; head yellow medially, brown on anterior margin and posterolaterally; pronotal lateral thirds brown, yellow medially; meso and metanota with light brown markings laterally; legs yellow; tergites II–VIII brown medially but yellow laterally, tergal lateral setae dark, also terminal setae of abdomen; forewing including clavus dark brown, paler toward apex; antennae mainly brown, segments III–IV yellow at base.
Head broad across eyes, ocellar setae III small and arising on anterior margins of ocellar triangle; maxillary palp with basal segment small and pale. Antennal segment II with few and weak microtrichia dorsally; III and IV with apical neck; inner sensorium on VI extending almost to apex of VII. Metanotal median setae arise behind margin, scarcely longer than lateral pair but stouter. Tergites with no sculpture mesad of setae S2; laterally with at least 12 rows of microtrichia.
Measurements
(
holotype
female in microns). Body length 1400. Head, length 125; width across eyes 185; ocellar setae
I 50
; ocellar setae
III 25.
Pronotum, length 100; width 190; anteromarginal setae 65; posteromarginal setae 25, 70, 65, 15. Tergal setae S1, on

, 65, 65, 50, 65, 40.
Male macroptera
. Similar to female in structure and colour, but abdomen paler.
Larvae II
. Surface of abdomen and thorax, but including only median area of pronotum, finely granulate (
Figs 11, 12
), remainder of pronotum smooth; on tergite IX the granulation grades into sharply pointed microtrichia at posterior; major setae capitate; head unusually broad.
Specimens examined
.
Holotype
female,
Kenya
, taken in quarantine at Melbourne,
Australia
, on leaves of
Catha edulis
,
2.vi.2009
(AQIS 002971), in the Natural History Museum, London.
Paratypes
:
5 females
with similar data except,
24.ii.2009
,
31.iii.2009
,
12.v.2009
,
26.v.2009
;
2 males
with similar data
17.v.2002
.
Paratype
specimens will be deposited in London, also in the
Kenya
Museum, Nairobi and the Australian National Insect Collection, Canberra.
Comments
. More than 10 immature specimens, including second instar larvae as well as both pupal instars, have also been intercepted by Australian quarantine together with the adults on the leaves of
Catha
. It is therefore evident that this is a plant on which this thrips breeds, but this should not be taken as evidence that the thrips is host specific.
