Eudyasmus simplex Heller, 1935: 198

( Fig. 10 )

Lectotype. Papua New Guinea: ♂, K. Wilhelmsland / Finshchafen // 1927 / 15 // Typus / Eudyasmus simplex Hr. (handwritten on red card) // LECTOTYPE Eudyasmus simplex Heller (handwritten on yellow card) ( SMTD). New Lectotype Designation. Heller (1935) does not state how many specimens he had of E. simplex , so we have selected the only specimen labeled “Typus” in Heller handwriting as the Lectotype.

Other Specimens Examined. Papua New Guinea: 1♂, Nadzab , Markham / R. val. NGuinea / 13 July 1944 / K.V. Krombein // E. fork Ngafir / Cr. 1000 – 3000 ft / na- tive trail // Ex Colln / KV Krombein ( USNM) ; 1♂, New Guinea: NE / Bupu R., Sitium Vill. / 19 km NE of Lae , 30+ / forest, 15.IV – 15.V ‘70// N.R. Spencer / Light Trap / Bishop ( BPBM) ; 2♀, Newguinea / v. Benningsen // Kani Geb // Coll v. Bennigsen ( SDEI) .

Diagnosis. TL 7.1–11.1 mm, EW 3.0– 5.1 mm. This species is nearly concolorous and lacks the distinct oblique macula or stripes on the sides of the pronotum and dorsum of its congeners. However, it does have a very thin transverse facia of whiteish-tan scales across the elytral base and two of the five specimens examined in this study also have a very faint sutural stripe on the elytra. The most distinct feature of E. simplex is the solitary white scales that are situated in each of the punctures on the dorsum are broadly spatulate and stand out in sharp contrast to the otherwise uniformly dark background scales. But at the elytral humeri, these normally whitish scales are dark and match the color of the surrounding fuscous scales. This gives the appearance of a pair of large sub-triangular black patches at the elytral humeri that are not found in any other species.

Distribution. PAPUA NEW GUINEA: Morobe Province ( Fig. 1 ).
