TYPE MATERIAL. Holotype – male, Australia: “ W. Australia: Kalibarri Nat.

Park, 600 km N Perth, 12–14.XII 1986, J.S. Noyes, NHM(E) 2002-109” ( BMNH).

The holotype is pinned. Genital segments has been removed and the genitalia dissected; these are in a small glass vial of glycerine pinned under the specimen.

DESCRIPTION. Metope elongate, nearly twice as long as wide between the eyes, slightly enlarged below the eyes above the clypeus ( Fig. 24 ). Lateral margins of metope roof-shapedly cover pedicel. Metope with distint median carina running from its straight upper margin through postclypeus and sublateral carinae running from its upper margin and indistinct in its lower third. Metopoclypeal suture weakly convex. Postclypeus with median carina. Anteclypeus without carina. Rostrum nearly reaching hind coxae. Second and third rostrum segments are almost equal in length.

Third rostrum segment conically narrowing apically. Pedicel shortly cylindrical.

Ocelli present. Coryphe transverse, with median carina; anterior margin strongly convex; posterior margin deeply concave ( Fig. 25 ). Lateral margins of coryphe nearly straight. Coryphe margins keel-shaped. Coryphe and metope joint at acute angle (in lateral view) ( Fig. 26 ). Pronotum with median carina and 2 rows of sensory pits with seta inside – upper row with 8 pits and lower row with 4 pits on each side besides median carina. Paradiscal fields relatively wide, each with a row of sensory pits. Paranotal lobes large and long, with trough-curved lower margin.

Mesonotum 1.5 times as long as pronotum, with smooth median and lateral carinae.

Tegulae small. Fore wings elongate, slightly enlarged apically ( Fig. 27 ), with narrow hypocostal plate. Basal cell large, oval. R 2 M 2 CuA 3. Radius and median furcating near to basal cell. Cubitus anterior furcating near to wing middle. Clavus as long as whole wing, close. Pcu fusing A 1 at clavus middle. Hind wings rudimentary. Hind tibia with 2 lateral spines in distal third and with 8 apical spines.

First metatarsomere slightly longer than second one, with 2 latero-apical and around

10 intermediate spines. Second metatarsomere with only 2 latero-apical spines.

COLORATION. General coloration light brown whitish ( Figs 45–47 ). Postclypeus with red lateral stripes besides of median carina. Rostrum with black second and third segments. Pro- and mesonotum whitish, with wide light brown median stripe, but median carinae whitish; sensory pits light brown. Paranotal lobes brown near to antennae, with whitish outer margins. Fore wings whitish, each with large brown area laing between R and CuA. Tegulae whitish. Legs light brown to brown. Apices of leg spines black. Episternae, epimerae, and abdomen including genital block brown. Styles whitish, with brown margins.

MALE GENITALIA ( Figs 28–31 ). Generally very similar to B. modestus .

Pygofer long (vertically), with slightly convex hind margin ( Fig. 28 ). Anal tube wide, narrowly rounded apically (in dorsal view) ( Fig. 31 ), with lateral margins turned down in shape of elongately rounded processes (in lateral view). Anal column (paraproct) long, almost half as long as anal tube. Connective with large and wide cup. Phallobase strongly curved – horse-shoe shaped (in lateral view),

wide in proximal half ( Fig. 28 ). Each dorso-lateral lobe with large elongately rounded process on its ventral margin (which is weakly sclerotized) above ventral aedeagal hooks (in lateral view) ( Figs 28, 30 ). Dorso-lateral lobes rounded apically,

each with oblique transverse carina. Aedeagus with pair of long (more than half as long as phallobase) narrow ventral hooks directed basally, pointed apically. Apical aedeagal processes bilobed apically. Style with convex hind margin and long and narrow capitulum without teeth ( Figs 28, 29 ).

FEMALE. Unknown.

TOTAL LENGTH. 3.0 mm.

DISTRIBUTION. Western Australia ( North of Perth ) .

“New Holl.” (BMNH), fore wing. Abbreviation: hp – hemicircularly protruding costal margin of fore wing.
