086287B53333FFECFEA5F909C177FD77.taxon	materials_examined	Type species: Megatrachelus chloris Faust, 1889. DIAGNOSIS. — Large apionids, usually well over 4.0 mm long (without rostrum), easily distinguished from members of other New Caledonian genera by inflated, pyriform elytra having markedly distinctly convex at least the inner intervals, and deeply impressed striae with always evident specific apical arrangement (isolated stria 9 reduced, 2 joining 7, and 8 free) shared only with the closely related genera Rhadinocyba and Himantapion. Unlike these two genera, in Megatracheloides the characters listed above are uniquely combined with profemur always longer and thicker than meso- and metafemur and armed with a tooth or spine, divaricate tarsal claws bearing long and thin, acute teeth, and the wing having almost complete anal cell.	en	Wanat, Marek (2008): The Apionidae (Coleoptera: Curculionoidea) of New Caledonia.

Females lay eggs singly to the fully developed flower buds (Fig. 110), the larva feeds on soft petals and generative organs inside the bud, which usually falls down on the ground soon after infection. Pupation takes place in the bud and teneral adult beetles appear on leaves in December-March, following extended flowering season of the host plants.	en	Wanat, Marek (2008): The Apionidae (Coleoptera: Curculionoidea) of New Caledonia.

VARIATION. — The specimens from Northern Province have weaker deve- loped elytral tubercles, practically missing in the population from Kopéto. The only studied male from Mt. Do has body almost black and aedegus slightly broader, shallower notched ventrally and stronger sinuate than in other studied specimens. BIOLOGY. — Maquis species, found primarily on Hibbertia pancheri (Brongn. & Gris) Briquet (Fig. 72), occasionally on H. lucens Brongn. & Gris and other spp. Adults feed on flower buds and underside of leaves (Figs 105, 106).	en	Wanat, Marek (2008): The Apionidae (Coleoptera: Curculionoidea) of New Caledonia.

086287B5333CFFEBFF47FD5EC634FDDE.taxon	description	DESCRIPTION. — Body length 4.6 - 7.6 mm. Coloration of elytra intensely blue-green. The following differences from M. chloris have been noticed (excepting those concerning morphological indices given in Table 3). Rostrum longer, particularly in female (Figs 3, 4, 8, 9), puncturation finer, often obsolescent; sulci on venter of pro- and mesorostrum obsolete. Antennae: scape m: 4.5 - 4.8 x, f: 5.3 - 6.8 x longer than wide, club as long or longer than the scape. Head with subocular keel obsolete to absent; vertex almost even throughout, impunctate. All elytral intervals evenly convex, without tubercles at angulation of elytral outline (Figs 6, 16). Mesoventrite with extremely weak median depression, without distinct median keel. Legs: base of profemur longitudinally or obliquely grooved; protarsus stouter, 2.6 - 2.9 x longer than wide, length / width ratios: ts 1 1.45 - 1.60, ts 2 0.8 - 0.9, ts 3 0.9 - 1.0, onychium 3.2 - 3.9, exceeding ts 3 by 0.25 - 0.30 length (Fig. 27). Male: profemoral tooth very large, always bifid, with secondary tooth of the same shape and more than half as long as the main one (Fig. 22). Abdominal V 5 broadly flattened in apical half, deeply emarginate (Fig. 33). S 8 very short, with weak emargination. S 9 with arms of fork broad and rounded (Fig. 74). Tegmen: parameroid lobes long and narrow, more than 3 x longer than fenestrae, at base with 5 - 7 short macrochaetae replaced with minute spines on the narrowed, distal parts; membranous lobes attached at inner side of parameroid lobes, hardly longer than fenestrae and much shorter than the outer extensions of parameroid lobes, basally with triangular, melanized areas, without clear microchaetae; fenestrae well margined, entirely closed; postfenestral plate complely divided; prostegium very long, narrowly divided, not TABLE 3. Morphological indices of Megatracheincised laterally (Fig. 69). Aedeagus: median lobe 4.0 - 4.5 x longer than broad, loides bidentipes. with short, blunt apex (Fig. 57), in profile weakly sinuate apically, with apical (Fig. 99), spermathecal duct narrowed shortly before its junction with bursa. VARIATION. — Beetles collected from Hibbertia baudouinii Brongn. & Gris with huge flowers are usually distinctly larger than those from other plant species. In large-sized specimens elytra are more elongate and profemoral are teeth better developed, in males symmetrically forked.

DIAGNOSTIC DESCRIPTION. — At first glance very similar to M. cornutus (see description above), distinct only in the characters list- ed below. Rostrum slightly shorter than in M. cornutus, particularly in ♀ (compare rl / mxrw and brl / eyl ratios in both species). Elytra: tubercle on the 6 th interval indistinct, blunt; intervals 3 - 6 weaker convex (Figs 49, 51); stria 1 shortened basally, not exceeding the level of scutellum’s tip and disjunctive with the basal rim of elytron (Fig. 55). Profemoral tooth in both sexes minute, conical, hardly longer than its basal width (Fig. 47).

Male: Membranous process between T 7 and T 8 at most 1.5 x longer than broad. Tegminal plate: outer membranous lobes very large, as broad as parameroid lobes and about as long as the remainder of the plate, entirely covering the inner lobes (Fig. 86). Aedeagus: pedon over 4.0 × longer than broad, with long, parallel-sided, abruptly separated apical half (Fig. 61), stronger sinuous in profile (Fig. 67). Female: Abdominal T 7 with more projecting tip and slightly concave lateral margins (Fig. 92). The remaining characters as in M. cornutus. Body length 4.7 - 6.2 mm.

ACKNOWLEDGMENTS I wish to express my sincerest thanks to the Direction de l’Environnement (Province Sud) and Direction du Développement Économique et de l’Environnement (Province Nord) for the issuance of permits to collect Apionidae in New Caledonia. I owe a special debt of gratitude to the following persons: BenoÎt Perignon, BenoÎt Michel, David Paulaud, and Joseph Manaute, of DENV Nouméa, for much advice and assistance, and for the permit to use scientists’ refuges in the Parc Provincial Rivière Bleue; Christian Mille and Sylvie Cazeres of IAC, Pocquereux, for their hospitality, guidance, and technical help in 2007; Jean-Jérome Cassan of DDEE, Pouembout, for his help and advice in Province Nord; late Henri Blaffart of Association Dayu Biik for his great help in field work and hospitality in Tiendanite; Martin Brinkert for his help in getting full access to the areas of Aoupinié and Tchamba; Jean Chazeau, Gilles Dagostini and JérÔme Munzinger of IRD, Nouméa for discussion and generous help in identification of plant species for this study. Hervé Jourdan and Veronique Perrin of IRD had a big part in the success of 2006 / 2007 expedition helping with custom procedures of the equipment. Sophie Rouys, Jörn Theuerkauf and Paweł Krzyżyński are thanked for a great logistic help, advice, nice company and long Polish talks during my stays on New Caledonia. I greatly thank Dariusz Skibiński and Roland Dobosz for their company and invaluable help during expeditions to New Caledonia. I am grateful to all the curators and coleopterists, who made their materials and comparative specimens available to me: Jane Beard and Max Barclay (BMNH), Marcel Cludts (IRB), Guillermo Kuschel (NZAC), Geoff Monteith (QLDM), Rolf Oberprieler (ANIC), Hélène Perrin (MNHN), Alexander Riedel (SMNK), Al Samuelson (BPBM). Roman Guziak is thanked for his counting computer programme helpful with morphological indices. Present contribution is a part of the studies conducted with financial support of the former State Committee of Scientific Research, Poland (currently the Ministry of Science and Higher Education), as a grant no. 3 P 04 C 08223.	en	Wanat, Marek (2008): The Apionidae (Coleoptera: Curculionoidea) of New Caledonia.
