Pterorthochaetes haroldi (Sharp, 1875)

Known distribution: Indonesia, East Malaysia, West Malaysia (Pahang), Singapore (Paulian 1978).

Remarks. The first author began a revision of the genus Pterorthochaetes in the late 90’s, the revision is still in progress. Based on the preliminary results of this revision the majority of records of P. haroldi (and P. incertus, which will probably become a junior synonym of P. haroldi) reported by Paulian (1978) (e.g. Java, Thailand, Vietnam, Sri Lanka, etc.) are wrong.
