Observational collection data.

One male, observed by Achmad Rian Dietra (Indonesia) in May of 2017. Indonesia: West Papua Province, Kaimana Regency, Aiduma Island.

Discussion. This is only known from photographs of a live individual taken by Achmad Rian Dietra (Indonesia). Based on pro- and mesofemoral lobes being strongly angular and not smoothly arcing from end to end, this individual belongs to the pygmaeum species group. This species group only has males known for six species: N. pygmaeum Redtenbacher, 1906, N. asekiense ( Größer, 2002), comb. nov., N. adisi Zompro & Größer, 2003, N. rentzi Brock & Größer, 2008, N. hasenpuschi Brock & Größer, 2008, and N. australianum Cumming, Le Tirant & Teemsma, 2018.

Based on the profemoral exterior lobe that is wider than the shaft width and not larger than the interior lobe, that rules out N. australianum (exterior lobe of profemora same width as shaft width; Fig. 11D View Figure 11 ) and N. adisi (exterior lobe of profemora larger than interior lobe; Fig. 11H View Figure 11 ). Nanophyllium rentzi (Fig. 18 View Figure 18 ) and N. asekiense ( Größer, 2002), comb. nov. (Fig. 17E, F View Figure 17 ), can also be ruled out as possible identifications, as their entire body coloration is green and the alae are completely transparent, in contrast this specimen from Aiduma Island has a brown body and dark tegmina and alae. The two remaining identification possibilities are N. pygmaeum and N. hasenpuschi which can easily be morphologically separated by the coloration of the alae, solid brown in N. pygmaeum or alae with a large transparent patch in N. hasenpuschi . Unfortunately, this individual has its wings closed so the interior color is impossible to see. A definitive identification is unfortunately not possible at this time. Geographically this individual is located near collection sites of both N. hasenpuschi and N. pygmaeum so no inference can be drawn from locality (Fig. 4 View Figure 4 ). This is however a unique opportunity to share photos of a live individual and to add a new distribution checkpoint to the map of Nanophyllium collection/observation localities (Fig. 15 View Figure 15 ). It is also possible that this individual represents an undescribed species on its own, or the male for an undescribed species based on one of the below females illustrated.
