Paśnik, G., 2007, Review of the New Zealand genus Ecomorypora CAMERON (Coleoptera, Staphylinidae: Aleocharinae), with description of three new species, Linzer biologische Beiträge 39 (2), pp. 1101-1110 : 1105

Ecomorypora longelytrata nov.sp. ( Figs 16-19 )

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 :: same data as holotype ( BMNH) ;: New Zealand, MC: Rakaia River , ca. 9 km W State Highway, 19.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. 16 ); body colour pitchy brown, elytra reddish-brown, 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 with fine 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 with fine meshed microsculpture; punctuation very fine and dense; pubescence at midline directed entirely anteriorly.

Elytra elongate, slightly wider than pronotum, at suture longer than pronotal length at midline; surface with obsolete microsculpture; punctuation fine and very 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 fine and dense; surface of tergites with fine transversely stretched isodiametric mesh microsculpture; last tergites without granules; tergite X as in Fig. 19 .

Male. Aedeagus as in Figs 17-18 .

Female unknown.

R e m a r k s Ecomorypora longelytrata is similar to E. densepunctata nov.sp., from which it can be distinguished by the distinct microsculpture of forebody, the finer punctuation of pronotum and abdomen, the different shape of tergite X an by the shape of aedeagus.
