Description.

Claval formula: 1-2-2-2-2-1. Number of clavomeres: 6. Color of antenna in female: radicle and A1-A6 light yellow, A7-A12 brown. Color of A7 of female: concolorous with clavomeres. Color of antenna in male: unknown. Color of head: reddish-brown. Color of mesosoma: reddish-brown. Color of metasoma: reddish-brown. Color of legs: light yellow-brown, fore legs darkest. Setation of frons: short, sparse. Sculpture of frons: punctate-rugose dorsally, transversely striate ventrally. Sculpture of vertex: punctate-rugose. Excavation on posteromedial vertex: present. Sculpture of posteromedial vertex: smooth. Sculpture of gena: rugose. Length of LOL: 1 OD. Length of POL: two times as long as LOL. Sculpture of dorsal pronotal area: areolate-rugose. Sculpture of lateral pronotal area: transversely striate. Sculpture of netrion: transversely rugose. Notaulus: absent. Mesoscutal humeral sulcus: not clearly differentiated from surrounding surface sculpture. Mesoscutal suprahumeral sulcus: not clearly differentiated from surrounding surface sculpture. Sculpture of mesoscutum: areolate-rugose. Parapsidial line: absent. Setation of mesoscutellum: absent medially. Sculpture of mesoscutellum: granulate posteriorly. Form of metascutellum: twice as long as wide, unsculptured. Sculpture of propodeum: rugose. Setation of plical area: present. Median area of the lateral propodeal area: absent. Sculpture of mesofemoral depression: transversely rugose. Setation of mesepisternum ventral to mesofemoral depression: sparse. Sculpture of mesepisternum ventral to mesofemoral depression: smooth dorsomedially, otherwise punctate-rugose. Setation of dorsal metapleural area: absent. Sculpture of dorsal metapleural area: smooth anteriorly, rugose posteriorly. Setation of ventral metapleural area: absent. Sculpture of ventral metapleural area: smooth. Length of horn on T1: reaching apex of mesoscutum. Sculpture of horn on T1: areolate-rugose basally and along margin of armilla, otherwise transversely aciculate. Sculpture of T1 posterior to armilla: transversely striate-rugose medially, longitudinally striate laterally, interstices rugose. Sculpture of T2: longitudinally weak medially, replaced by areolate surface sculpture, interstices areolate-rugose. Sculpture of T3: longitudinally striate, interstices areolate. Sculpture of T4: transversely striate laterally, faintly areolate medially. Sculpture of T5: weakly longitudinally striate laterally, punctate medially. Sculpture of T6: punctate. Length of T6 in female: 1.25 times maximum width. Relative length of hind basitarsus in female: 2 times as long as remaining tarsomeres. Relative length of hind basitarsus in male: unknown.

Diagnosis.

Three characters are unique to P. halua sp. nov.: (1) the posterior vertex is excavated and devoid of surface sculpture; (2) the clava is 6-merous; and (3) the median area on the lateral propodeal area is absent. Otherwise, P. halua sp. nov. is most likely to be confused with P. gunnelsi sp. nov. based on its size and habitus similarities.

Etymology.

The species name is taken from the Indonesian word for smooth, in reference to the sculpture of the declivity on the vertex. The epithet is treated as a noun in apposition.

Material examined.

Holotype, female: Indonesia: W. Kalimantan Gunung Palung Nat. Pk. 15 JUN-15 AUG 1991 Darling, Rosichon, Sutrisno | Cabang Panti Res. Sta. 1 rainforest. 100-400m Alluvial light gap 1°15'S, 110°5'E Malaise trap head IIS 910122, OSUC 359932 (deposited in MZB) . Paratypes: Indonesia: 2 females, OSUC 359933 (CNCI); 359934 (ROME) .

Comments.

The three females that comprise the type series are virtually identical.
