New taxa and notes on spine-headed katydids (Orthoptera: Conocephalinae: Agraeciini) from the Philippines

摘要

The diversity of the Agraeciini spine-headed katydids (Orthoptera: Tettigonioidea: Conocephalinae) in Southeast Asia remains poorly known, with species still awaiting discovery. Recent field collections in the Philippines resulted in the discovery of three novel species and redescription of two known species of Agraeciini, namely, (1) Anthracites furvuseques sp. nov. from Siargao in Mindanao, a species close to A. major Hebard, 1922; (2) Axylus mabinii sp. nov. from Luzon: (3) a new variant in Axylus c.f. philippinus (Hebard, 1922); (4) Salomona lumadae sp. nov. from Siargao in Mindanao; and (5) Salomona brevicollis Stal, 1877 comb. resurr. is a valid species distinct from Salomona maculifrons Stal, 1877.
