Lea coll 12 0 6 \ Cyphon fenestratus Id. by J. Armstrong \ det fenestratus (MV, T-21999). Habitus . BL 2.6−2.8mm , BL/BW ~1.7, slender. Light brown, head darkest, humeral area a little paler than rest. One specimen has a faint curved macula on the elytron like N. donnabuangi has. The head punctures are fine, dense, and rough, the integument appears scaly. Pronotal punctures little larger, granular, spaced, integument shiny. Elytral punctures normal, much larger. Semi-erect short yellowish pilosity. Male ( Figs. 82, 86 ). Pala truncate and parallel-sided. The parameroids are of equal width over their entire length. They curve around the trigonium, their apex is scooped out, spoon-like. The flat trigonium is longer than the parameroids, it resembles a bottle: base about three times wider than bottleneck, apex again wider, truncate or indistinctly concave, with a few rough scales along edge. The separate flat parameres have a long basal rod and a short, caudally toothed plate. Left and right paramere of a given specimen often differ in details ( Fig. 91 ). Female . Unknown. Etymology . Endemic to King Island. The name is a noun in apposition, an agglutination of two Latin nouns in the genitive case meaning “from the island of the king“.
