Heiss, E., 2011, Bruneiaptera tarmanni nov. gen., nov. sp., a new apterous Carventinae from Brunei Darussalam (Hemiptera: Heteroptera: Aradidae), Linzer biologische Beiträge 43 (1), pp. 331-336 : 332

Bruneiaptera nov. gen.

T y p e s p e c i e s Bruneiaptera tarmanni nov.sp.

D i a g n o s i s The new genus is easily distinguished from the other apterous Carventinae genera recorded from Borneo e.g. Froeschnerissa KORMILEV 1986, Zoroaptera DRAKE 1957, Sandakaptera VÁSÁRHELYI 1988 and Enkopicephalus HEISS 2010 by the fused bottle shaped smooth median plate of meso- and metanotum followed posterorly by a smooth rectangular plate of fused mtg I+II. At a first view it resembles the monotypic genus Ainocoris ( DRAKE 1957, 1958) described from Julu (Jolo) Island in the Philippines, however in Ainocoris the pentagonal smooth median plate is depressed and extends into the pronotum and its head is subquadrate and distinctly shorter (fig. 8).

D e s c r i p t i o n: Apterous, body surface glabrous and shiny beneath incrustation, colour piceous.

H e a d: At least 1.32 as long as wide, genae produced over clypeus, apices triangular and diverging anteriorly; antennae about 2.1 as long as width of head, segment I thickest and longest, the following ones thinner and shorter, antenniferous lobes diverging anteriorly, apices acute; eyes oval inserted in head; postocular lobes with a distinct tubercle, sinuately converging to constricted collar; rostrum arising from a slit like atrium, shorter than head.

P r o n o t u m Collar ring like and smooth, separated from anterolateral angles of pronotum by deep incisures; disk of pronotum with a median longitudinal furrow; surface irregularly rugose, lateral margins straight and converging to blunt anterolateral angles; posterior margin sinuate, a deep furrow separates it from mesonotum.

M e s o n o t u m:Themediansmoothbottleshapedplateistriangular on mesonotum, then widening posteriorly and subrectangular on metanotum; lateral sclerites with rugose surface, separated by sutures from each other and metanotum.

M e t a n o t u m: Consisting of the smooth median plate and ovate rugose lateral sclerites; the fusion line to mtg I+II is marked by a sinuate suture.

M e d i o t e r g i t e s I+II: They are fused but separated from tergal plate by a deep sulcus; the median subrectangular smooth plate is at a lower level than the elevated posterior margin of the preceding median plate; lateral parts rugose anteriorly and smooth posteriorly.

A b d o m e n:Tergalplatewithaslightlyelevatedmedianridge,laterallywithdistinct apodemal impressions; deltg II+III fused, IV-VII separated by deep sulci; lateral margins of deltg II-VII showing the exposed rim of the dorsally reflexed vltg II-VII bearing the spiracles which are visible from above; spiracles VIII sublateral on paratergites VIII.

V e n t e r: Surface smooth except lateral parts, sternites separated by deep sulci with the usual pattern of apodemal impressions.

L e g s: Femora and tibiae straight and nearly cylindrical, surface with fine setigerous granules, tibal comb on fore legs present; claws with apically enlarged pseudopulvilli.

E t y m o l o g y: Named after Brunei and the apterous condition.
