M a t e r i a l e x a m i n e d: Holotype, Brunei Darussalam, Temburong, Kuala Belalong Field Studies Center, mixed Dipterocarp forest 60-300m, 16-20 IV 1993 lg. E. Heiss, paratypes 2

3 collected with holotype, 1 from the same area 2-8 V 1995 lg. E. Heiss.

D e s c r i p t i o n: Male, apterous, color of body piceous, legs and antennae of lighter colour; surface of body shiny, legs and antennae beset with fine setigerous tubercles.

H e a d: 1.33 as long as wide (32/24); genae produced over free clypeus with triangular anteriorly diverging apices leaving a median cleft; antenniferous lobes diverging anteriorly its apices acute; antennae 2.1 as long as head (50.5/24), segment I longest and thickest, II-IV thinner and shorter, II shortest, IV fusiform; length of antennal segments I/II/III/IV = 17.5/ 8/ 14/ 11; eyes oblong inserted in head; postocular lobes laterally with 1-2 acute tubercles then sinuately converging posteriorly to constricted collar; vertex with a median tuberculate ridge and lateral smooth ovate callosities, rostral groove deep with carinate margins, closed posteriorly.

P r o n o t u m:About 2.6 as wide as long (42/16); collar ring like, smooth and glabrous, laterally separated from anterolateral lobes by deep incisures; disk with a median longitudinal sulcus and an anterior transverse triangular sclerite; lateral parts consisting of a smaller ovate and a larger polygonal sclerite with irregularly rugose surface; lateral margins straightly converging anteriorly, anterolateral lobes truncate; posterior margin sinuate and separated from mesonotum by a deep furrow.

M e s o n o t u m Median smooth plate of triangular shape, laterally with a smaller ovate and a wider subrectangular sclerite with rugose surface, these separated by deep sulci; lateral margins straight and converging anteriorly; metanotum separated by furrows laterally of median plate.

M e t a n o t u m: Fused median plate wide and raised toward posterior margin, its lateral margins slightly converging posteriorly; structure of lateral parts of disk as of mesonotum; posterior margin bisinuate, separated from fused transverse mtg I+II by a suture.

A b d o m e n Tergal plate consisting of mtg III-VI about as wide as long with a slightly elevated median ridge, laterad with ovate callosities marking the apodemal impressions; lateral margins slightly convex; deltg II-VII with visible rim of dorsally reflexed vltg II-VII on which the spiracles II-VII are exposed and visible from above; spiracles VIII subterminal on paratergites VIII.

G e n i t a l i c s t r u c t u r e s: Pygophore pyriform, narrowing posteriorly, surface rugose (Fig. 6,7); parameres slender as Fig. 1-5.

F e m a l e: Generally as male but of slightly lager size, the reflexed rim of vltg VII is triangular and bears the spiracle VII, paratergites VIII subtriangular and shorter than truncate tergite IX.

M e a s u r e m e n t s Holotype: Length 3.9mm, width pronotum 1.05mm, mesonotum 1.4mm, metanotum 1.5mm, abdomen across tergite IV 1.8mm.

Female paratypes: Length 4.25mm, with / length of head 26/35, prontum 48/18; width mesonotum 1.6mm, metanotum 1.7mm, abdomen across tergite IV 2.05mm; ratio length of antennae / width of head 2.08; length of antennal segments I/II/III/IV = 19/9/15/11.

E t y m o l o g y: This species is dedicated to my friend Dr.Gerhard Tarmann, curator of the insect collections at the Tiroler Landesmuseum Ferdinadeum Innsbruck, in occasion of his 60 th birthday, whose hospitality and the facilities made available at the museum for my work are very appreciated.
