Pteridobaris maritima (Roelofs)

( Figs. 13 , 20 )

Baris maritima Roelofs 1875: 181 .

Syntypes from Japan, without further collecting data ( BMNH, NKMB, RBINS); one examined. Transferred to Pteridobaris by Morimoto & Yoshihara (1996).

Baris quinquecarinata Zaslavskij 1956: 351 .

Holotype male, “Pekin”, without further collecting data ( ZIN); examined. New synonymy.

Diagnosis. Species of Pteridobaris Morimoto & Yoshihara have one distinct and several small denticles on the ventral side of the femora, most conspicuously on the profemur; most other Oriental genera with armed femora have single or paired denticles. Pteridobaris maritima ( Fig. 13 ) has five dorsal carinae on the rostrum, which are absent in a similar, undescribed species from Hainan, China (HBU, IZCAS). Morimoto & Yoshihara (1996) mentioned six undescribed species from Taiwan, the Philippines, Thailand and Malaya.

Notes. Zaslavskij (1956) distinguished B. quinquecarinata from B. maritima based on the dorsally carinate rostrum. We examined the types and found no difference, although the carination can be more subtle in females.

Distribution. The species occurs in S China (Fujian, Guangxi, Guizhou, Hong Kong), Japan and Vietnam ( Fig. 20 ). The record from Beijing ( Zaslavskij 1956) is unconfirmed.

Biology. Nothing is known about the life history of Pteridobaris species except that P. maritima and an undescribed species have been collected from ferns ( Morimoto & Yoshihara 1996). The only other known baridines associated with ferns are species of the New World genera Lamprobaris Champion and Lissobaris Champion (A. Howden, J. Prena, unpubl. data).
