Aleurotrachelus fissistigmae Takahashi, 1931: 264 .

Material examined. Lectotype puparium (here designated) and paralectotypes: Taiwan, Shinten, 14 puparia on Fissistigma oldhamii , 14.vi.1931, R. Takahashi, TARI, Taiwan.

Other material: Taiwan: Suisha, 7 puparia on F. oldhamii , 17.vi.1933, R. Takahashi; Sitozan, 4 puparia, on F. oldhamii , 15.vi.1938, R. Takahashi; Suisha, 14 puparia on F. oldhamii , 11.vi.1933, R. Takahashi ( TARI); Fushan, 17 puparia on 5 slides, on Pericampylus glaucus , 15.vi.1994, K. C. Chou; 20 puparia on 6 slides, on F. oldhamii , 16.vi.1994, K. C. Chou; Taipei, 3 puparia on F. oldhami , 16.iii.2009, A. K. Dubey ( NTU).

Host plants. Fissistigma oldhamii ( Takahashi, 1931) ; Pericampylus glaucus (new record).

Distribution. Taiwan.

Remarks. The lectotype puparium of this species is selected from among 14 syntypes on one slide and it is nearly central puparium from right side of the slide, and marked by a circle on cover slip ( Fig. 73 ). The puparia of this species are unique among Aleurotrachelus species known from Taiwan by the following combination of characters: longer than wide and sharply pointed marginal teeth, densely scattered submedian dorsal pores on cephalothorax and abdomen, nine pairs of minute submarginal setae, rhachisform abdominal segments, dorsal setae reaching well beyond margin, and medially elevated cuticle along with the longitudinal molting suture. Some of the examined puparia of this species were oval, and tip of lingula extended beyond posterior margin of the orifice. In a puparium examined from Pericampylus glaucus , the meso-, and metathoracic setae were seven times shorter than the cephalic setae. Puparia of this species were found together with Aleuroclava sp. on Fissistigma oldhamii .
