Ecomorypora densepunctata nov.sp. ( Figs 12-15 )

T y p e m a t e r i a l: Holotype :: New Zealand, AK: Orere stream banks, 2.I.1984, P.M. Hammond ( BMNH) . Paratypes :: New Zealand, 3 km NE Cardrona, banks of Cardrona river , 500 m, 3.II.1984, P.M. Hammond ( BMNH) ;: New Zealand, MK: Hooker Valley , 3-5 km N Hermitage, 750-830 m, 22.I.1984, P.M. Hammond ( BMNH) .

D e s c r i p t i o n: Body. Length 4.2-4.5 mm, convex, parallel-sided, glossy (Fig. 6); head and pronotum pitchy brown, elytra and abdomen brownish-red, tergites V-VI blackish, antennae and legs brown, tarsi red.

Head circular in outline, convex, glossy, narrower than pronotum, widest across eyes; eyes relatively small, protruding from lateral contours of head, length of each seen from above shorter than postocular region; surface of head without microsculpture; punctuation fine and dense; pubescence short and dense, directed inward. Antennae long, very weakly increase in width apically, antennomere 3 longer than 2, antennomeres 4-10 longer than wide, decreasing in length.

Pronotum quadrate, moderately convex, glossy, widest in apical third, lateral sides gradually narrowed in straight line to rounded hind angles; before base with transverse impression, surface lacking microsculpture; punctuation moderately fine and dense; pubescence at midline directed anteriorly.

Elytra elongate, slightly wider than pronotum, at suture longer than pronotal length at midline; surface without microsculpture; punctuation relatively fine and dense, interstices between punctures smaller than their diameter, pubescence short and dense.

Abdomen parallel-sided, bases of tergites III-VI each with deep transverse impression, impressions punctuate, tergal punctuation relatively coarse and dense; surface of tergites with fine transversely stretched isodiametric mesh microsculpture; surface of tergites VI and VII covered by moderately large granules; tergite X as in Fig. 15 .

Male. Aedeagus as in Figs 13-14 .

Female unknown.

R e m a r k s Ecomorypora densepunctata is very similar to E. pseudogranulata nov.sp., from which it can be distinguished by its smaller size, the pronotal pubescence directed entirely anteriorly, the coarser punctuation of pronotum and abdomen and by the shape of tergite VIII and aedeagus.
