Eudyasmus praecox Faust, 1898: 177

( Fig. 9 )

Lectotype. Papua New Guinea: 1♂, Mailu, / Brit. N.G., / July 95. // praecox Faust (handwritten) // Coll J. Faust / Ankauf 1900 // Type (on red card) // LECTOTYPE Eudyasmus praecox Faust (handwritten on yellow card) ( SMTD). New Lectotype Designation. Faust’s collection contains two specimens with “type” labels and we select this male specimen to be the name bearing type.

Paralectotype. 1♀, same label data as the lectotype // PARALECTOTYPE / Eudyasmus praecox Faust (handwritten on blue card) ( SMTD) .

Other Specimens Examined. Papua New Guinea: 1♂, NEW GUINEA, PAPUA / Kokoda – Pitoki / 450m . III-24-1956 // J. L. Gressitt / Collector ( BPBM) .

Diagnosis. TL 7.7–8.6 mm, EW 3.1–3.6 mm. This species is most easily confused with E. albertisii but can be distinguished from it and its other congeners by the solid medial longitudinal vitta of whitish-tan scales that runs the full length of the dorsum from the apex of the pronotum to the tip of the elytra. Like E. albertisii and E. basalis sp. nov. this species has oblique, white markings on each side of the pronotum. However, in E. praecox these markings form stripes that run laterally from the posteroapical margin of the pronotum (starting near the postocular lobes) reaching the dorsolateral basal margin and are visible in dorsal view near the base. There is no transverse fascia on the elytra in this species, however, there is a white, rectangular patch of scales laterally on each elytral humerus (adjoining the lateral stripe from the pronotum).

Distribution. PAPUA NEW GUINEA: Central and Oro Province ( Fig. 1 ).
