Naddia aureomontis nov.sp.

(Fig. 9)

Holotype: E-MALAYSIA, Sabah, Crocker Range, Gg. Emas 1650-1800 m, 30.IV-25.V.1996, leg. Strba & Hergovits (in NHMW).

Description: Proportions of holotype: length: 22 mm; length of head: 3.0; total length of head: 3.5; breadth of head: 3.8; length of eye: 1.0; length of temple: 1.8; length of antenna: 4.3; length of pronotum: 3.5; breadth of pronotum: 3.25; length of elytron: 3.5; breadth of elytra: 3.8. Habitus: fig. 9.

Antennae short, the first three segments slightly elongate, the following two globose, the rest increasingly transverse, segments 8 to10 asymmetrical. Hind wings not examined, but in view of the small size and depressed form of the elytra probably micropterous and non-functional, although the tergite VII bears a very narrow palisade fringe (it may be significant that this is the only Naddia species found at high altitude in Borneo; however at least one micropterous species has been found at lower altitudes in China).

Integument entirely black; antennae and legs black. Fore-body with some very sparse, inconspicuous paler pubescence and short dark setae on the sides, most numerous on pronotum; apical margins of elytra with a sparse fringe of paler hairs and longer dark setae; abdominal with an increasing extensive middle area of dense black pubescence; tergite VII without such pubescence but with long recumbent black setae, the punctures and setae sparser posteriorly; tergite VIII with coarse irregular puncturation bearing short pale hairs and some black setae; all tergites with lateral patches of brassy pubescence, these patches reduced to very narrow antero-lateral fringes on tergite VI.

Sculpture of head forming very coarse irregular longitudinal rugae; sculpture of pronotum likewise coarse, composed laterally and posteriorly of individual large, close umbilicate punctures, these merging on disc to form irregular vermiculate rugae and leaving a narrow impunctate mid-longitudinal band interrupted in the middle; puncturation of elytra sub-rugose, consisting of close umbilicate punctures; sculpture of sparsely pubescent abdominal tergite III with some coarse transverse rugae.

Male: unknown.
