Teabooma princeps Distant

( Figs 1 , 3, 6, 8)

Teabooma princeps Distant, 1914: 373 .

Redescription (submacropterous forms only): Body bronze with copper tinge, its dorsal surface alutaceous; head and anterior part of pronotum slightly shiny, and sometimes more blackish in shade than other body parts. Head with two primary setae only, the secondary setae absent; clypeus as long as the paraclypei, without a subapical pair of setae, its surface impunctate, with a few transverse, more or less visible, striae in its apical half; paraclypei densely coarsely punctured; puncturation reaching the lateral clypeal margins (Fig. 3). Ocular index 3.4–4.1. Antennae four-segmented, pale brown to ochraceous, the second segment longest. Rostrum brown or ochraceous, reaching between the median and posterior coxae, sporadically surpassing the posterior coxae and reaching at most the anterior margin of the 1st visible abdominal segment. Gular plates punctured with large coarse punctures close to bucculae.

Lateral parts of pronotum somewhat broadened and flattened, especially at its posterior third. Pronotal disc, except calli, densely coarsely punctured, its puncturation denser in front of the calli and in the anterolateral parts; short longitudinal wrinkles present just behind calli; punctures on pronotal disc a little larger than those on the dorsal head surface. Each lateral pronotal margin with 1–2 setigerous punctures at its anterior part (setae are usually torn out and therefore unnoticeable); lateral pronotal carinae narrow. Propleuron alutaceous, its depression with large coarse punctures. Evaporative areas large, that of mesopleuron with large, deep punctures. Scutellum long; its disc, except for the anterolateral angles and for the apex, with almost evenly scattered punctures; scutellar puncturation sparser than that of the anterior and lateral parts of pronotal disc. Corium almost evenly punctured, the puncturation a little denser than those of the scutellum; clavo-corial suture almost indistinct, meso-exocorial suture better visible, but also incomplete. Exocorium somewhat flattened, its lateral part slightly uprised. Costa very narrow, without setigerous punctures. Hemelytral membrane from milky white to brown, shorter and narrower than the abdomen, membranal veins distinctly visible. Coxae and femora black or dark brown, tibiae and tarsi yellowish brown or ochraceous, tibial spines blackish brown; anterior tibiae apically broadened; middle and posterior tibiae slender and almost cylindrical.

Abdominal sterna black or almost black, glossy in the middle, their sides conspicuously punctured; sternal postero-lateral angles rounded, and distinctly projecting out ( Fig. 1 ), sometimes ventrally and dorsally with pale brown or even yellowish brown patches.

Paramere as in Fig. 6; aedeagus with 2nd conjunctival appendages short, only slightly projecting out (Fig. 8); male genital capsule, with more or less deep insinuation in ventral view.

Other material examined: 1 female: Nlle Caledonie, 12.iii.1986, J Boudinot Réc., Muséum Paris (Muséum National d’Histoire Naturelle, Paris, France); 2 males, 3 females: New Caledonia, Col d’Amieu, 1800–2000’, 12–15 Dec., 1973, G.B. & R.S. Monteith, UQIC Reg. 36211 (University of Queensland Insect Collection, Brisbane, Australia). 1 male: New Caledonia, 11997, 21 0 37’S x 165 0 49’E, 480m., Col d’Amieu, west slope, 6–30 Dec. 2004, rainforest, pitfall traps, G. Monteith (Queensland Museum, Brisbane, Australia).

Note: Body length of the type specimen given in the original description by Distant (1914), was 18 mm, whereas, it is actually only 16.38 mm.
