Ophthalmothrips longiceps (Haga)

Pyrgothrips longiceps Haga, 1975: 264 .

Ophthalmothrips longiceps (Haga) : Mound & Palmer, 1983: 71; Han, 1997: 337; Okajima, 2006: 138.

Diagnosis. Head about two times as long as wide; head elongate, preocular projection wider than long; postocular setae well-developed, but shorter than interocellar setae, blunt at apex. Antennae 8-segmented, segment III longest, about 5 times as long as wide, III with 1+1 sense cones, IV with 2+2 (Fig. 19). Maxillary stylets V-shaped. Pronotum with five pairs of developed major setae, pointed to blunt at apex. Mesopresternum boat-shaped. Fore tarsal tooth absent in both sexes. Pelta triangular, with entire reticulation (Fig. 25); abdominal tergites II–VII with two pairs of well-developed wing-retaining setae; tube shorter than head, anal setae slightly shorter than tube.

Distribution. China (Hainan, Taiwan); Japan.

Material examined. China, Taiwan (Kenting), 1♀ 1♂, from dead leaves, 22–24.V.1972, coll. Shuji Okajima ( IZCAS); China, Hainan, 1♂, 11.IV.1958, coll. Xiangling Meng ( IZCAS) .

Comments. Described from Japan on decayed grasses by Haga (1975), this species was recorded from Taiwan, China by Han (1997). Here, one female and one male from Taiwan, and one male from Hainan were studied. O. longiceps is similar to O. elongatus Li & Dang , sp. nov. by having an elongate preocular projection of the head and lacking fore tarsal teeth in both sexes, but they have obvious distinct characters (see Comments of the new species).
