Aleyroctonus pilatus Masner & Huggert, 1989: 38 (original description); Vlug 1995: 10 (cataloged, type information).

Description.

Body length of female: 1.18-1.23 mm (n=2). Body length of male: 0.99-1.06 mm (n=2). Color of radicle: yellow; black. Color of mesosoma: black. Color of metasoma: black. Length of LOL: equal to or greater than 2 OD. Length of POL: greater than 2 OD. Genal carina: present. Length of clava: longer than A3-A7. Length of A4: approximately as long as A3. Shape of mesoscutum in lateral view: flat to slightly convex. Path of notauli: subparallel. Shape of notaulus: same width throughout. Posterior mesoscutellar sulcus: incomplete medially. Setation of posterior mesoscutellar sulcus: dense. Sculpture of posterior mesoscutellar sulcus: smooth. Rim of posterior mesoscutellar sulcus: absent. Sculpture of metanotal trough: smooth. Prespecular sulcus: absent; present. Sculpture of prespecular sulcus: smooth; weakly costate. Setation of metapleuron: dense. Length of metabasitarsus: shorter than tarsomeres 2-5. Setation of anterolateral pits on T2: dense. Rs of fore wing: spectral. M of fore wing: nebulous. Rs+M of fore wing: nebulous. Shape of ventral adeagal lobe: rounded.

Diagnosis.

The genal carina and ovoid clava that is longer than A3-A7 readily separates A. pilatus from other species in the genus.

Material examined.

Paratypes: MALAYSIA: 6 females, 2 unsexed, OSUC 697943-697945 (BMNH); OSUC 697946-697950 (CNCI). Other material: AUSTRALIA : 3 females, 5 males, OSUC 697909, 697911-697912 (ANIC); OSUC 697918, 697921-697922 (CNCI); NHMUK010370460, OSUC697954 (NHMUK).

Comments.

The distribution of this species is expanded to include northeast and southeast Queensland, Australia. In addition, Carver and Reid (1996) mentioned the presence of A. pilatus in Papua New Guinea; however, we did not examine specimens from that location.
