TYPE MATERIAL. — New Caledonia. Holotype ♂, labelled “ New Caledonia (N); 20°56.1’S 165°17.7’E [= 20.9351°S 165.2946°E]; Pic d’Amoa, 220-250 m; 14.I.2007, maquis; ex Hibbertia wagapii ; leg. M. Wanat & R. Dobosz” ( MNHN) . Paratypes (39 ♂♂ 29 ♀♀): Province Nord: Pic d’Amoa , 20.9351°S 165.2946°E, 220-350 m, 14-15.I.2007, maquis; leg. MW & RD ( MW, IRD, IACP, USMB, IRB, BMNH) .

DIAGNOSIS. — The species resembles M. chloris in body size, shape of rostrum, and has a close host plant, a broadleaved Hibbertia wagapii . It differs from M. chloris primarily in much duller body coloration, stronger microreticulate integument, more regularly oval elytra with evenly convex intervals, less inflated basally profemoral tooth in male, asymmetrical apically and differently shaped aedeagus (Figs 59, 65), and the peculiar 5 th abdominal ventrite of female, with well separated in outline and deeply divided apical lobes (Figs 38, 39).

DESCRIPTION. — Body 4.4-6.2 mm long, whole with slight bluish TABLE 2. Morphological indices of Megatracheloides millei reflex. Rostrum shiny, finely and densely punctured to the apex, (mean value in parentheses).

in profile weakly arched (Figs 14, 15, 20, 21). Antennal segments

cally bent, parallel-sided apex (Fig. 59), in profile markedly arched,

distinctly sinuous in apical part (Fig. 65); flagellum as in Fig. 79.

Female: Antennal insertion 0.35-0.38. Profemur almost alike that

of male. Abdominal V5 apically flexible, with a pair of distinct lobes separated from its outline (Fig. 39), in back view forming a high rim divided by deep and broad fossa (Fig. 38). Terminalia similar as in M. chloris : ovipositor as in fig. 95; styli with several apical setae; apices of coxitae with numerous pores and a few short setae; bursa with finer membrane, more inflated; spermatheca shorter and stouter than in M. chloris (Fig. 103).

The remaining characters as in M. chloris . Morphological indices in Table 2.

BIOLOGY. — Collected in maquis from Hibbertia wagapii .

DISTRIBUTION. — Pic d’Amoa (Northern Province).

ETYMOLOGY. — Named in honour of Christian Mille (IACP), in thanks for his great hospitality and help in field and laboratory work on New Caledonia in January 2007.
