Kranzithrips gen.n.

Diagnosis. Macropterous, fore wing setae small, widely spaced, many cilia straight but some wavy; clavus with discal seta ( Fig. 48 ). Antennae 8-segmented, III–IV with sensorium long and simple; segment I with no dorso-apical setae. Head almost as long as wide ( Fig. 51 ), ocellar setae I absent but with longitudinal ridge anterior to first ocellus; compound eyes with no pigmented facets; maxillary palps 2-segmented. Pronotum weakly trapezoidal, 2 pairs of posteroangular setae. Metanotum irregularly reticulate medially, median setae small, distant from anterior margin ( Fig. 48 ); campaniform sensilla present. Prosternal basantra with one pair of setae, ferna continuous medially; mesothoracic sternopleural sutures complete; meso and metafurcae without spinula; meta pre-episternum broad and band-like with one seta. Abdominal tergite I with no craspedum, II–VIII with pale, broad and weakly lobed craspedum ( Fig. 47 ), campaniform sensilla close to posterior margin except on VIII; IX with 2 pairs of campaniform sensilla, median dorsal setae slender; X with split almost complete. Sternite II with 2 pairs of marginal setae, III–VI with 3 pairs and craspedum of 5 broad and overlapping lobes ( Fig. 49 ), VII with no craspedum medially. Male similar to female, sternites III–VII with broad pore plate; tergite IX with pair of stout, thorn-like setae forming a single median process ( Fig. 50 ).

Type species Kranzithrips mareebai sp.n.

Comments. The new species for which this genus is erected is similar in general appearance to the species of Yoshinothrips , but has tergal and sternal craspeda. The tergal craspeda and position of the campaniform sensilla suggest a relationship to Bregmatothrips , but unlike the species of that genus it lacks dorso-apical setae on the first antennal segment, the head and pronotum are different in shape, and the male has sternal pore plates and a different chaetotaxy on tergite IX ( Figs 34 , 50 ). The lack of ocellar setae pair I on the head, and the male with large sternal pore plates and large setae on the ninth tergite suggest this genus is not closely related to the Australian genera, Aliceathrips , Masamithrips and Monothrips .
