description: Naddia ignipennis nov.sp.
(Figs 6, 6a, 6al)
1 Holotype: INDONESIA, Borneo, Kalimantan Tengah, Busang/Rekut confl. 0˚03’S 113˚59’E, Flight Intercept FIT 9, Brendell/Mendel, August 2001, Barito Ulu 2001, BMNH(E) 2001-191 (in NHML); 1 paratype: ibid., but FIT 7 (in RCO); 1 paratype: MALAYSIA, Sabah, Tawau, 16- 24.ii.2012, 4.76N 117.54E, 399 m Alt., Coll. C.L. Gray, SAFE project area, F.I.T Riparian forest strip in oil palm, OUMNH-2013-056 (in OUMNH).
Description: Proportions of holotype: length: 19 mm; length of head: 2.85; total length of head: 3.5; breadth of head: 3.5; length of eye: 1.1; length of temple: 1.6; length of antenna: 4.5; length of pronotum: 3.45; breadth of pronotum: 3.1; length of elytron: 4.5; breadth of elytra: 4.3. Habitus: fig. 6.
Antennomeres elongate but relatively short; antennomeres 4-10 subquadrate, the general appearance of antennae therefore moniliform (= like a string of beads); all segments symmetrical.
Integument black, that of head and pronotum with a distinct bluish reflex, contrasting with colour of elytra and abdomen; antennae and legs black. Pubescence of disc of head and pronotum dark, short, inconspicuous, the sides of both with fairly dense white pubescence; Ground pubescence of elytra dark, sparse, inconspicuous; in addition the elytra each bear three patches of silvery pubescence, one broad, extending posteriad from humeral angles, one narrow behind this in posterior half of elytron, and one short patch on the declivous lateral portion of elytron; each elytron in addition with a large, very conspicuous fascia of dense coppery red pubescence; abdominal tergites 3-8 with sparse, short dark pubescence, the sides with narrow elongate patches of silvery pubescence decreasing in length posteriad, each segment with some lateral dark setae; pro- and mesotibia with pale pubescence and spines.
Sculpture of fore-body unique within the genus: head with dense umbilicate punctures in posterior half, very sparse on an umbonate median portion between the eyes, and frons practically impunctate; both these areas glossy; other glossy impunctate areas are on the emargination of occipital area and the anterior half of neck; pronotum with sparse small umbilicate punctures, the interstices as broad as or broader than the diameter of punctures, flat and glossy, the puncturation leaving a broad, entire but irregular glossy midlongitudinal band; puncturation of elytra very fine and dense, rugose, consisting mostly of small umbilicate punctures, the surface therefore dull, in sharp contrast to head and pronotum, and even to abdomen; sculpture of abdominal tergites consisting of sparse punctures of different sizes, the integument with microsculpture, noticeably denser on anterior parts of tergites VI and VII, which therefore appear duller than posterior parts
Male: sternite VII unmodified; sternite VIII with an extremely small apical emargination; aedoeagus: figs 6a, 6al, in ventral view the median lobe gradually dilated distally, the apex evenly, broadly rounded; ventral extension of basal sclerite long, the distal part narrow, parallel-sided, the apex shallowly bifurcate; paramere very short, bilobed, with apical setae clearly visible on the tips of the lobes.
The only other known species of Naddia with a similar very dense patch of red pubescence on the elytra is N. decipiens CAM. from continental Asia, but in that species the pubescence is more extensive, and the sculpture of the head and pronotum is of the usual sub-rugose kind, albeit with an entire mid-longitudinal band on the pronotum. The type of sparse puncturation of the fore-body of N. ignipennis is on its own sufficient to recognise the species.
