Treatment

Neohydatothrips bellisi View in CoL sp.n.

( Figs 41–45 View FIGURES 37 – 45 )

Female macroptera. Strongly bicoloured; head brown but postoccipital region and pronotum yellow; meso and metanotum dark brown, meso and metasternum light brown; abdominal segment I yellow with antecostal ridge interrupted medially, II–VI yellow with III variably shaded anterolaterally, antecostal ridges weakly shaded but only laterally, VII–VIII dark brown, IX–X mainly yellow; legs yellow; forewings banded, dark at base including clavus, with pale sub-basal area before brown band, with second light brown band before pale apex. Antennal segments mainly yellow, with faint shadings at apex of IV–VI. Head with occipital carina close to eyes; ocellar triangle without sculpture lines; ocellar setae III close together between posterior margins of posterior ocelli; two or three pairs of postocular setae, median pair long; postoccipital region with transverse narrow reticulation. Pronotum transversely reticulate without internal markings, blotch weakly defined. Mesonotum with closely spaced striations, and small lines between the major striae. Metanotum with linear reticulation, many small linear markings between the major sculpture lines; posterior half sharply paler. Metasternal anterior margin straight. Forewing with distal setae widely spaced, no setae on second vein; wing apex with no sub-apical lobe. Tergites I–VI medially without marginal microtrichia; V–VI with few discal microtrichia medially. Sternites II–VII medially without marginal microtrichia, discal microtrichia not extending mesad of setae S2; VII with marginal setae arising on discal area.

Measurements. Holotype female in microns: Body length 1100. Head, length 140; width across eyes 160. Pronotum, length 95; width 185. Forewing length 730. Antennal segments III–VIII length 55, 40, 53, 40, 7, 12.

Male. Similar to female, abdominal segment VIII brown; sternites without glandular areas.

Material studied. Holotype female, Queensland, 30km north of Cloncurry, from unknown shrub, 1.viii.1993 (LAM2560), in ANIC.

Paratypes: 3 females, 3 males taken with holotype; Northern Territory, Humpty Doo, I female from dead Eucalyptus leaves, 25.xii.1996; Bathurst Island, from Ficus opposita , 14.v.1999; Western Australia, Kununurra, 4 females from chillies, 7.ix.2005.

Comments. This species has been taken widely across northern Australia, but with no host association. The colour pattern is unique, predominantly whitish-yellow but with dark markings on the head and pterothorax, and two dark bands on the wings. Moreover, the position of the ocellar setae between the hind ocelli is unique within this genus.

Sericothrips diana Girault 1929: 3

This species is probably widespread in eastern Australia. It has been found commonly near Canberra on the leaves of two low-growing Fabaceae View in CoL species, including Dyllwynia seeberi and Pultenaea procumbens View in CoL .

Female macroptera. Body strongly bicoloured; head brown with postoccipital region and anterior half of pronotum yellow; pronotal blotch and pteronota, also meso and metasternum, dark brown; abdominal segments I–VI yellow, VII–X dark brown; legs mainly brown; forewings with pale sub-basal area then uniformly light brown. Head with occipital carina close to eyes; ocellar triangle irregularly sculptured; ocellar setae III within anterior margins of triangle; three pairs of postocular setae, median pair long and arising near posterior ocelli; postoccipital region transversely striate. Pronotum anterior third transversely reticulate without internal markings; blotch transversely striate with many markings between the major lines. Mesonotum and metanotum with many linear markings between the major sculpture lines, metanotal reticulation equiangular to linear. Metasternal anterior margin with shallow emargination. Forewing with one or two setae distally on second vein, apparently displaced from first vein; wing apex with sub-apical lobe well developed. Tergites I–VI medially without marginal microtrichia; antecostal ridge interrupted medially on tergite I. Sternites II–VII medially without marginal microtrichia, but a few discal microtrichia extend mesad of setae S1 near posterior margin.

Male. Similar to female, abdominal segment VII yellow; sternites without glandular areas.
