Allotisis rara sp. nov.

(®gures 3, 9, 21)

Description

Female. Body length: 9.2 mm.

Colour. Antennae, disc of pronotum and legs reddish brown; head, pronotal nodules and tubercles and abdomen dark reddish brown; remaining parts dark reddish brown to blackish brown. Elytra with a wide, slightly raised yellowish brown ivory fascia, covering between basal 1.3/10 and apical 3.5/10; the fascia divided transversely by a dark zigzag band; a fairly large yellowish brown ivory area of irregular form on disc just before apex (®gure 9).

Head. Distinctly narrower than prothorax; frons and vertex with dense rugose punctures and fairly dense golden depressed hairs; a few long erect hairs at lateral sides of vertex. No carinae between antennal tubercles; distance between lower lobes of eyes more than twice but less than three times distance between antennal socket and lateral angle of post clypeus, and slightly more than 1.5 times distance between upper lobes of eyes. Antennae slightly longer than body; segments 3±7 with fairly long apical spines; segment 3 more than ®ve times but less than seven times length of its apical spine, and distinctly longer than scape, segments 4 or 5; scape not groove d above.

Thorax and abdomen. Prothorax slightly shorter than wide. Pronotum rugose, granulose and un-nitid, with ®ve distinctly raised, granulose and un-nitid nodules on disc: central one oval, anterior pair of irregular form and posterior pair subround; the interspace of nodules with fairly dense and large punctures, each producing a long whitish erect hair, and with dense golden depressed hairs; fairly large rounded tubercles at lateral sides. Scutellum subtriangular with dense golden depressed hairs on disc. Matesternum with dense punctures and dense depressed hairs. Elytra subparallel or slightly tapering, subnitid, slightly more than three times length of prothorax; apex subtruncate with a small spine at marginal angle; dense, large and deep punctures throughtout elytra except disc just before apex, about one-quarter of the punctures producing long whitish erect hairs, and the remaining punctures producing very short (vague) depressed hairs. Abdomen with sparse punctures and depressed hairs.

Ovipositor. As in ®gure 21.

Male. Unknown.

Biology Hosts unknown. Adult was collected in August.

Distribution North-eastern Western Australia (®gure 3).

Comments

This new species closely resembles A. labyrinthina sp. nov. but diOEers in having elytral colour pattern of regular form, i.e. elytra with a wide ivory fascia which is divided transversely by a zigzag dark band; distance between lower lobes of eyes more than twice distance between antennal socket and lateral angle of post clypeus; prothorax shorter than wide.
