ABSTRACT
Anochetus maryatiae, a new species of
Formicidae from the subfamily Ponerinae, tribe Ponerini from Ulu Gombak was
described and illustrated. This ant genus was last studied in Malaysia by Brown
in 1978. 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, pronotum width, propodeum height,
petiole length, petiole height, dorsal petiole width, cephalix index and
mandibular index. It was followed by a 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, A.
maryatie varies with A. tua in having smaller total length, less than
7.5 mm and lighter colour.
Keywords: Ants; Anochetus; Formicidae; Malaysia;

ABSTRAK
Satu spesies baru Formicidae iaitu Anochetus maryatiae daripada
subfamili Ponerinae dan tribus Ponerini yang dijumpai di Ulu Gombak telah
dikenalpasti dan diperihalkan. Kali terakhir genus semut ini dikaji ialah pada
tahun 1978. Pemerhatian dilakukan pada ciri-siri morfologi termasuklah
ukuran-ukuran parameter jumlah panjangnya, panjang kepala, lebar kepala,
panjang mandibel, panjang skap, panjang antena, panjang maksimum mata, jarak
okulomandibel, panjang funikul pada segmen 1 hingga 4, lebar pronotom,
ketinggian propodeum, panjang petiol, ketinggian petiol, lebar dorsal petiol,
indeks cephaliks dan indeks mandibul. Ia diikuti oleh diagnosis ringkas,
penghuraian struktur morfologi, mikroskulptur, pilositi dan perbincangan.
Walaupun A. maryatiae seakan-akan serupa dengan Anochetus tua, ia boleh
dibezakan daripada spesies lain kerana ia mempunyai pronotum yang retikulat. Ia
merupakan satu spesies yang mengandungi mikroskulptur pada pronotum. Selain itu A. maryatiae berlainan dengan A. tua kerana A. tua mempunyai
panjang badan yang lebih pendek iaitu kurang daripada 7.5 mm dan berwarna lebih
cerah.
