Terthrothrips Karny

Of the 25 species listed in this genus, 22 are from the Neotropics ( Mound 1977a) and three from southern Japan, all living in leaf-litter. Terthrothrips ananthakrishnani Kudo , described from Nepal ( Kudo 1978) and recorded from southern Japan ( Okajima 2006), is here recorded from Australia ( Fig. 45 ). Four females and one male (all macropterae) of this species have been identified from Australia, based on the descriptions of Kudo and Okajima, collected at Kuranda, Queensland, on dead leaves, 4.xi.2008. Two specimens in ANIC taken near Darwin have the head strongly reticulate, and possibly also represent either this genus or Eurythrips , a closely related genus ( Mound 1977a).

Diagnosis. Head usually longer than wide, slightly prolonged in front of eyes, cheeks incut behind eyes; postocular setae long, capitate; mouth-cone short and rounded, stylets short, V-shaped; antennae 8-segmented, VIII constricted basally, III and IV each with 2 or 3 sensoria; pronotum with 3 or 4 slender, capitate setae, anteromarginals reduced; notopleural sutures complete or nearly complete; basantra usually present; mesopraesternum transverse; no sternopleural sutures; fore tarsal tooth present in both sexes; fore wings, if present, parallel-sided without duplicated cilia; pelta variable; tergites II–VII each with 2 pairs of wing retaining setae; tube shorter than head, anal setae much shorter than tube, about twice as long as apical width of tube; male sternite VIII without pore plate.
