Allotisis furva sp. nov.

(®gures 3, 13, 28, 29)

Description

Male. Body length: 7.9-12.5 mm.

Colour. Anteclpeus, labrum, maxillary and labial palpi, antennae and legs reddish brown or dark reddish brown, remaining parts blackish brown or dark reddish brown. A fairly wide, slightly raised yellowish brown ivory fascia on disc of elytra, wide at external margin and narrow at suture, covering between basal 1.3/10± 1.7/10 and apical 4.3/10±4.9/10; the fascia divided transversely by a zigzag dark band: posterior part wide, more or less straight and anterior part much narrower, zigzag or broken into two or three spots on each elytron; a fairly large subround yellowish brown spot on disc just before apex (®gure 13).

Head. Distinctly narrower than prothorax; frons and vertex heavily depressed so the area from vertex to frons almost ¯attened, with spares or fairly sparse punctures and depressed hairs; a few long erect hairs at lateral sides of vertex and frons. No carinae between antennal tubercles; distance between lower lobes of eyes twice as long as or slightly less than twice distance between antennal socket and lateral angle of post clypeus, and more than 1.5 times but less than twice distance between upper lobes of eyes. Antennae distinctly longer than body; segments 3±6 with small apical spines; segment 3 slightly more than seven times length of its apical spine, and distinctly longer than scape, segments 4 or 5; scape not grooved above.

Thorax and abdomen. Prothorax longer than wide. Pronotum rugged and rugose, with ®ve distinctly raised and two slightly raised nodules on disc: central and anterior pair of nodules more or less smooth and nitid; medial pair (smallest) and posterior pair rugged, rugose and un-nitid; the interspace of nodules rugged and rugose with sparse but large punctures, each producing a long whitish erect hair, and with fairly sparse pale depressed hairs; very prominent but rounded tubercles at lateral sides. Scutellum triangular with dense pale depressed hairs on disc. Metasternum with dense punctures and depressed hairs. Elytra subparallel or slightly tapering, nitid, slightly less than three times length of prothorax; apex subtruncate with small spine or tooth at marginal angle; basal half of disc with dense, large and deep punctures, about onequarters of the punctures producing long whitish yellow erect hairs; apical half of disc with dense but small and shallow punctures, producing fairly dense but very short depressed hairs and sparse long whitish yellow erect hairs. Abdomen with sparse punctures and sparse depressed hairs.

Male terminalia. Apex of median lobe pointed to sharply pointed. Unspined region of internal sac slightly more than 1.3 times as long as spined region; spined region divided into two sections: ®rst section absent; second section with dense simple large and long spines and simple small and long spines; third section almost ®ve times as long as second section, with dense simple large and long spines and sparse basally forked spines; a small area between second and third sections unspined (®gure 28). Eighth sternite rounded at sides; setae absent in mid-terminal area; no microspines and processes on ventral surface. Apex of eighth tergite rounded.

Female. Body length: 9.1±14.1 mm.

Antennae slightly longer than body; segments 3±7 with small apical spines. Elytra slightly more than three times length of prothorax.

Ovipositor. As in ®gure 29.

Variation

The dark band dividing the ivory fascia of the elytra may be incomplete or vague and the ivory spot on disc before apex varies from subround to suboval.

Biology Hosts unknown. Adults were collected in June, November and December.

Distribution

Southern, western and north-western Victoria, northern and north-eastern New South Wales and south-eastern Queensland (®gure 3).

Comments

Many specimens of this new species were wrongly identi®ed and labelled as A. discreta (Pascoe) in various Australian museums. It closely resembles the latter species but diOEers in having the area from vertex to frons ¯attened, with fairly sparse punctures; prothorax wider; the central and anterior pair of nodules on disc of pronotum more or less smooth and nitid; the apex of the elytron with a small spine or tooth at marginal angle.
