Specimens examined. Four females, Papua New Guinea, Northern Province, Popondetta, October 1980 to May 1981 (UN 1212, 1214, 1506, 1507).

This species was described from a single specimen collected at “Sattelberg” ( Fig. 3 View FIGURES 1 – 5 ), from the same geographical region as Popondetta ( Fig. 32 View FIGURE 32 ). The type specimen belonged to Prof. Gustav Hauser (1856 – 1935) and was preserved in his collection. My colleague Stephan Gottwald told me (in litt.) that the Hauser collection was acquired by the Museum für Naturkunde der Humboldt Universitat zu Berlin, Germany in 1938 and he kindly took photographs of the type and sent them to me for comparison ( Figs. 3–5 View FIGURES 1 – 5 ). They are in concordance with my specimens ( Figs. 1, 2 View FIGURES 1 – 5 ).

Redescription of figured specimen (UN 1507). Collection date April 1981. Head: L 21 mm, W 6,8 mm, L/W=3,1. Black, shining with fine punctuation. H= 3,9 mm. V=2,2, F=1,8. Deep triangular depression between eyes with short pubescence and faint reflections of metallic-greenish hue. Deep furrow at middle of depression, broadest in middle. Eyes large, prominent. Antennae: Reaching just over humerus. First antennomere greenish blue, slightly bent, following antennomeres brown. Pronotum: Nearly trapezoidal but anterior half almost cylindrical, L/W=0,7, dark brown with metallic lustre. Median furrow fine, widening towards base. At each side depressed dfp spot with green metallic lustre anteriorly and golden red posteriorly. Scutellum: Small, oval, depressed, with golden lustre. Elytra: Concolorous with head and pronotum, attenuating behind shoulders, slightly impressed towards metacoxae, thereafter attenuate to apices in a smooth curve. Lateroposterior borders strongly denticulate, apices bidentate. Elytra weakly striate, punctures partly confluent. Each elytron with five golden dfp impressions: first near anterior border, next two just posterior to humeral protuberance, from 4th striae to lateral border, one just posterior to metacoxa and one small elongate impression near apices. Sides in bright illumination reflect red hue. Legs: Femora and proximal half of tibiae green, distal part of tibiae and tarsi yellow-brown, claw dark. Prosternum: Broad, strongly punctuated medially. Ventral side dark, central parts of ventrites dark brown, no dfp. Anal ventrite with narrow incision.

From the examination of the photographs ( Figs. 4, 5 View FIGURES 1 – 5 ) of the type specimen, it is apparently male.

Remarks: This species is very much like M. (Metamroczkowskia) loriae ( Kerremans, 1895) . The differences ( Table 1) can be seen on the additional pictures of the holotype and a specimen from the central part of Papua New Guinea, Kamanea Village, Aseki, Morobe Province 2005 (UN 1820).

Metataenia hauseri ( Figs. 2, 4, 5 View FIGURES 1 – 5 ) Metataenia loriae ( Figs. 7, 8, 9, 11 View FIGURES 6 – 11 ) Pronotum strongly attenuate from base until middle, then Pronotum is straight from base then attenuate towards almost cylindrically towards anterior margin anterior margin
