Pliacanthopus Giglio-Tos, 1927

= Xanthomantis Giglio-Tos, 1915

= Polyacanthopus Hebard, 1920

= Oligocanthopus Beier, 1935

Three subgenera are currently recognized, two of them monotypic. The genus was previously known as Xanthomantis Giglio-Tos, 1915 , but this name was preoccupied, so Uvarov (1940b) chose the next available name, of subgenus Pliacanthopus , as replacement, without further commenting on former nominate subgenus Xanthomantis . The nomenclatory change went unnoticed by subsequent authors (e. g. Beier 1964, 1968, Ehrmann 2002, Otte & Spearman 2005), until Koçak & Kemal (2008) confirmed the homonymy and proposed Malayamantis as replacement name for subgenus Xanthomantis . Monotypic subgenera endemic to Borneo. Arboricolous.

Pliacanthopus (Pliacanthopus) mantispoides ( Hebard, 1920) §

Polyacanthopus mantispoides Hebard, 1920

Distribution. E Borneo: Sabah: Sandakan ( Hebard 1920); Kalimantan: Mentawir ( Beier 1958).

Pliacanthopus (Oligocanthopus) ornatus (Beier, 1935) §

Distribution. Borneo: Lebang Hara ( Beier 1931b); Sabah: Danum Valley (CSUB).

Pliacanthopus (Malayamantis) flavus (Giglio-Tos, 1915) §

Xanthomantis flava Giglio-Tos, 1915

Distribution. Singapore (?), Borneo ( Giglio-Tos 1915b, Hebard 1920, Ehrmann 2002; AFUW). Bornean records. Sarawak: Mt. Dulit ( Beier 1937); Sabah: N Sabah (AFUW), Poring Hot Springs (SMNK),

Danum Valley ( Helmkampf et al. 2007); Kalimantan: Lebang Hara ( Beier 1931a), Bidang Menabai ( Beier 1931a). Remarks. The Singapore specimen mentioned by Hebard (1920) is the only record known outside of Borneo.

It may possibly refer to P. (M.) malayanus Beier, 1931 , which would make P. (M.) flavus a Bornean endemic.
