Anochetus maryatii, a new species of ponerinae (hymenoptera: formicidae)

Abstract

Anochetus maryatii, a new species of Formicidae from the subfamily Ponerinae, tribe Ponerini from Ulu Gombak was described and illustrated. Photos of this species were a/so included. This genus was last studied in Malaysia by Brown 31 years ago. Observations were made on morphometric characters which included parameter measurements of total length, head length, head width, mandible length, scape length, antenna length, maximum eye length, oculomandibular distance, funicular length segment 1 to 4, pronoturn width, propodeum height, petiole length, petiole height, dorsal petiole width, cephalix index alld mandubular index. It is followed by brief diagnosis, description of morphological structure, microsculpture, pilosity and discussion. Although it has resemblance with Anochetus tua, it could be easily distinguished from other species in having reticulate pronotum. This is the only species from Malaysia with such microsculpture on the pronotum. In addition to that, it varies with A. tua in having smaller total length, less than 7.5 mm and lighter colour.
