description
Description. Preantennal head broadly rounded (Fig. 3). Male scape longer than female (Fig. 4), but not much wider and not otherwise modified; male flagellomere I with distal extension. Head chaetotaxy as in Fig. 3. Lateral margins of temples more or less parallel in male. Thoracic and abdominal segments and chaetotaxy as in Figs 1 – 2. Distal abdomen of male as in Fig. 42; sternal plate VII apparently separate from subgenital plate; stylus short, spatulate; distal margin of segment XI only barely concave, lateral corners not extended distally. Male genitalia as in Figs 5 – 7. Distal rugosity of mesosome somewhat coarse. Ventral sclerite with slightly concave anterior margin and only one visible gpmes on each side. Gonopore does not approach distal margin of mesosome. Parameres slender, convergent, with slightly bulging heads; pst 1 in distal fourth of paramere. Female sternal plate VII may have median bulge on distal margin (Fig. 8), but this is not clear due to poor sclerotisation. Median bulge of vulval margin pronounced, with 4 – 6 vss on each side; lateral lobes with 15 – 20 long, slender vms on each side. Lateral margin of claspers with 5 – 7 lateral setae on each side. Measurements as in Table 1. Non-type material examined: Ex Arborophila crudigularis: 5 ♀, Taiwan [as Formosa], Nov. 1898, coll. R. Meinertzhagen, 3595, NHMUK 010682415 (NHML). 1 ♁, 1 ♀, Taiwan [as Formosa], Apr. 1912, no collector, 16, NHMUK 010682414 (NHML).
discussion
Remarks. Price et al. (2003: 203) listed Arborophila brunneopectus (Blyth, 1855) and Arborophila cambodiana Delacour & Jabouille, 1928 as hosts of “ Oxylipeurus formosanus ”, citing Emerson & Elbel (1957) as a source for A. brunneopectus, but none for A. cambodiana. We have not examined any specimen from A. cambodiana, but our specimens examined from A. brunneopectus are not conspecific with R. (F.) formosanus (see below under Reticulipeurus (Forcipurellus) species 1). Therefore, these two hosts are not included here.
