Material examined.

Holotype, f (MNHN): "MUSEUM PARIS / NOUV. GALLES DU SUD / COLL. NOUALHIER 1898".

Description.

Colouration: Head ochraceous, posterior part of eye stalks with irregular brownish marking. Eyes reddish, ocelli hyaline. Antennae missing in the single examined specimen. Labiomeres dark ochraceous. Thorax. Pronotum ochraceous with brownish punctation and an infuscate transversal band across pronotal callosities. Scutellum entirely dark brownish. Hemelytra semi-hyaline, ochraceous with brownish punctation and an irregular infuscate spot on the corium. Thoracic pleurites and sternites dark brownish except prosternal collar, supracoxal lobes and peritreme; propleurite with an ochraceous spot dorsally. Abdomen dark brownish both dorsally and ventrally with a whitish longitudinal band at dorsal part of sternites.

Structure: Head. Median furrow of vertex short, hardly surpassing base of clypeus. Antennomeres missing. Labial trough Y-shaped with suture reduced, reaching approximately midline of head. Relative lengths of labiomeres: 1.00: 0.85: 1.32: 1:38. Thorax. Pronotum with dense and deep punctation except anterior margin, pronotal callosities and posterior margin with humeral angles. Pronotal callosities confluent. Pronotum length to basal width: 1.00: 1.76. Scutellum with trifurcate carina apically reduced. Hemelytra submacropterous. Scutellum length to basal width: 1.00: 1.06. Clavus with an incomplete row of punctures at corial margin. Corium punctate along margin of clavus, Cu, between M-R and costa in apical half. Exocorium slightly widened subapically. Membrane short, not surpassing apex of abdomen.

Measurements. Body length: 4.20; head length: 0.53; head width: 1.66; lengths of labiomeres I-IV: 0.36-0.30-0.47-0.49; pronotum length: 0.88; pronotum width: 1.54; scutellum length: 0.88; scutellum width: 0.83.

Diagnosis.

U. malipatili sp. nov. resembles U. boonei sp. nov. and both subspecies of U. maai in colouration and markings, but its cup-shaped labial trough and the presence of a minute furrow on its clypeus readily distinguishes it from the Indomalayan representatives of the genus.

Distribution.

The single known specimen is from an unknown locality in New South Wales, Australia.
