Phylladothrips bispinosus (Okajima)

Paradexiothrips bispinosus Okajima, 1984: 731.

Material examined.

Holotype, ♀ (TUA), Japan, Mindanao , Mt. Apo, Agko, on dead Palmaceae leaves, 4.viii.1979 (S. Okajima); paratypes, 1♀ 1♂ (TUA), with the same data as holotype.

Comments.

Described from Mindanao, Philippines on dead Arecaceae leaves, this species was transferred to Phylladothrips from Paradexiothrips by Okajima (1988). However, it can be distinguished by tergite VIII with only one posterior pair of wing-retaining setae. It is similar to P. pallidus described from Taiwan in having well-developed postocellar setae with apex expanded (Fig. 2 ), but their differences are given in the key. In addition, the broader stylets are somewhat similar to those of Idolothripinae species, and Okajima (1984) recorded lots of small fungal spores in the gut of the holotype female. Paratype males of this species have been studied, and setae S2 on tergite IX are short, a condition that is non-typical in this genus.
