Trisinuata apicula sp. nov.

Holotype. Male. NEW GUINEA. North East : 146.40E, 7.22S, Wau, Bulolo River, 850–900m, 24.viii.1965, J. and M. S. ( BPBM).

Paratype s (3). Same locality as holotype, male 4.ii.1966, JS ( BPBM) . Morobe District, 4 miles n Wau elev. C 2800 feet, near Kunai creek Lae road, 15.xi.1969, J. E. Lloyd, male (G263) ( ANIC) . Morobe District, Mt Missim , 880–1050m, 8–9.ii.1963, J S. male ( BPBM) .

Diagnosis. Superficially similar to both Tri. papuae and Tri similispapuae , distinguished by the yellow pronotum, which may be dark margined laterally; elytra dark brown; elytral apex truncate, PLP narrow and T8 with asymmetrical flanges.

Male. 5–5.5 mm long. Colour: pronotum bright shiny pale orange yellow with a very fine dark border (without dark margin in Kunai Creek male); remainder of body dark brown except for narrow pale posteromedian area on V5, largely pale LO in V6, 7 (darker markings of these segments indicated as stippling in Ballantyne 1987a Fig. 13q ), apical 3 tergites and reflexed margins of V6, 7 pale brown. Pronotum: 0.8–0.9 mm long; 1.4–1.5 mm wide; punctures broad, shallow, some contiguous, some separated by their width in median area of disc. Head: moderately depressed between eyes; GHW 0.9–1.3 mm; ASD = ASW. Elytron: apices truncate, outer margin (B) slightly curved, inner margin (C) sinuous ( Ballantyne 1987a Fig. 13o ). LO in V7 extending into PLP ( Ballantyne 1987a Fig. 13q ) or not (G236); MPP shallowly emarginated, posterolateral corners very short and acute. Flanges of T8 asymmetrical ( Ballantyne 1987a Fig. 13r ).

Etymology. The name apicula (Latin, apicula, ae = bee) is a play on words, referring to the designation of these specimens as Species B ( Ballantyne & McLean 1970; Ballantyne 1987a).

Remarks. Ballantyne and McLean (1970) briefly described and illustrated a single male with unusual deflexed elytral apices as "Species B". Ballantyne (1987a:162) described an additional Wau male. Two additional males are associated and the treatment formalised here. The apical labial palpomere is not dentate on its inner margin, and the apparent dentition observed by Ballantyne (1987a) is attributed to a clumping of hairs.
