Description: Proportions (of a male from Danum valley): length: 15 mm; length of head: 2.0; total length of head: 2.5; breadth of head: 2.8; length of eye: 0.9; length of temples: 1.1; length of antenna: 2.4; length of pronotum: 2.7; breadth of pronotum: 2.6; length of elytron: 3.1; breadth of elytra: 3.25. Habitus: fig. 3.

Eyes smaller than in N. iacobi , shorter than temples. Antennae as in N. iacobi .

Colouration of integument as in N. iacobi . Antennae darker than in N. iacobi , frankly black; legs rufo-testaceous. Head, pronotum and abdomen likewise with black pubescence, but head also with sparse, fine yellowish pubescence covering most of base, and conspicuous patches of brassy pubescence on temples; pubescence of elytra as in N. iacobi ; abdominal tergites III-VI with dense short black pubescence, without any brassy pubescence; the two large fasciae of abdominal tergite VII of N. iacobi are fused in N. germana to occupy the entire anterior 2/3rd of the segment, the hairs radiating in all directions from two centres; the pubescence is paler, bright brassy, not golden as in N. iacobi .

Sculpture of head and pronotum as in N. iacobi but conspicuously finer and denser; midlongitudinal band entire or almost so, showing as a long narrow shiny line; puncturation of elytra as in N. iacobi but the shallow umbilicate punctures much more widely spaced, the interstices even more deeply and closely wrinkled, so that the surface appears duller; puncturation of abdominal tergites much finer, not noticeably sparser on posterior part of each tergite.

Male: sternite VII modified; sternite VIII with a small, very shallow emargination, as in N. iacobi ; aedoeagus: figs 3a, 3al, the median lobe broader and much shorter than in N. drescheri , with more broadly rounded apex; ventral extension of basal sclerite broad, about 2 ½ times as long as wide, the apex sub-truncate, a little concave, with acute anterior angles; paramere adpressed, very broad and short but more salient and evident than in N. drescheri , the apical margin slightly concave.

Variability: a single from SABAH: Danum Valley, B.R.L, f.i.t., 14-16.II.2007, G. de Rougemont (in RCO) (" germana ab.?" in key above) attributed here to this species differs from the types in colour and in the shape of the head, as described in the key, and is somewhat larger: proportions: length: 15 mm; length of head: 2.5; total length of head: 2.8; breadth of head: 3.00; length of pronotum: 2.8; breadth of pronotum: 2.6; length of elytron: 3.2; breadth of elytra: 3.5. These differences make it appear to belong to a different species, but as a single male (of typical proportions) of N. germana from the same area has a slightly rufescent pronotum, it is thought more prudent to provisionally regard this female as simply an aberrant individual of N. germana .

This species is so far only recorded from the north (Sabah), whereas the similar N. iacobi nov.sp. occupies the west of the Island ( Sarawak and Brunei, and probably central Kalimantan on the other side of the dividing range of mountains between Sarawak and Kalimantan. As far as is known the two species are allopatric.
