Opilo congruus var. abdominalis Schenkling 1901: 106 (unavailable, occupied by Opilo abdominalis Fairmaire, 1891 , an available name in synonymy with Thanasimodes gigas (Laporte, 1836)) .

Type material examined. LECTOTYPE (here designated): Victoria: Mansfld. (Vict.) Australia EX COLL. F. SCHNEIDER // Coll. S. Schenkling // Schenkling det. // COTYPUS (1, SDEI). PARALECTOTYPE (here designated): Australia (state not known): Australie CH. FRENCH // Determin S. Schenkling // Coll. R.I.Sc.N.B. // Holotype // Opilo congruus var. nov. abdominalis Schklg (IRSNB) ( Fig. 182 ).

Comment on lectotype designation. Despite specimen labelling, Schenkling (1901) neglected to fix the holotype as no reference to specimens accompanied his brief description of abdominalis ; the two located ‘types’ are therefore syntypes ( ICZN 1999: Article 73.2) and available for lectotype designation ( ICZN 1999: Article 74.1). We have chosen to follow recommendation 74D ( ICZN 1999), rather than following the status implied by specimen labels, because: a) the act of designating the SDEI specimen as the lectotype provides this taxon with a more specific type locality; and b) most of Schenkling’s type material is held at SDEI. Condition of lectotype: The specimen is very dirty but complete, though with the left elytron split behind the fascia. Condition of paralectotype: The entire mesothoracic leg, the right mesotarsus and left metatarsus are missing; the specimen is, otherwise, clean and in good condition.

Diagnosis. Antennal flagellomeres slender; elytra dark with orange to yellowish fasciate and apical maculations (humeral maculae absent), fasciae meeting at suture, 8 th stria beginning before fascia, all striae terminating before apical maculae; femora entirely dark.

Notopilo reduncus stat. rev., nom. nov. is superficially similar to N. congruus (Newman) comb. nov. though is easily recognised by its entirely black legs.

Redescription. Habitus: Fig. 168 . Total length: 8–16.5 mm (lectotype 12.5mm). Head: Cranium black, clypeus and supra-antennal elevations with a deep reddish hue, anteclypeus, labrum, antennae and palpi dark brown to orange-brown; eyes separated by 0.6–0.8 eye widths (lectotype 0.61); frons impressed and densely punctate at narrowest point, surface immediately above impression even, medially smooth, punctate laterally, nearer to vertex more densely punctated, surface below narrowest point unevenly punctated, smoother laterally and below; genae and submentum wrinkled; ratio of exterior to interior edges of terminal palpomeres about 1.5:1 (maxillae) and 2.5:1 (labium); antennae reaching near base of pronotum; eyes and most of cranium vested with erect pale setae, frons with shorter medially-directed setae. Prothorax: Black, pronotal collar and arch with deep reddish hue; pronotum 1.17–1.3 times longer than wide (lectotype 1.3), sides round, widest just anterior of middle; subapical depression deeply v-shaped, disc with deep central sulcus (sulcus smooth, more open than linear), a shallow sulcus on each side, and five weakly glabrous tubercles (one on each side just posterior to pronotal collar, one medially at base and one each either side and slightly posterior of that), surface smooth in appearance though with small seta-associated punctations; moderately distributed with short fine multi-directional setae and long erect setae. Pterothorax: Ventrites brown, barely punctate, sparsely vested with short pale and occasional long setae; elytra ( Fig. 25 ) blackish-brown (similar shade to pronotal disc) with orange markings (each elytron with a large apical macula and a narrow, often weakly curved, transverse fascia reaching the suture and lateral margins—its anterior margin at elytral mid-length); length to width ratio 2.4–2.8:1 (lectotype 2.74); 8 th stria beginning between first and eighth punctation of 7 th stria, inner and outer striae terminating within fascia, other striae terminating between fascia and apical maculae, punctation lacking nodules, very large and complete anterior to fascia, smaller with posterior edge indistinct or ‘open’ posterior of fascia, epipleurae extending well into apical curve, interstriae with very fine short semi-reclinate setae and less frequent longer thicker erect setae; hindwing with CuA 3+4 cross-vein complete, CuA 1 cross-veins incomplete, MP 3+4 absent basad of CuA 1 crossvein, RP vein incurvate. Legs: Femora, tibiae and tarsi dark brown to blackish-brown, ventral tarsal pads ( Fig. 19 ) yellowish; profemora very slightly swollen, other femora slender. Abdomen: Ventrites dark brown to orange-brown, posterior margins paler. Male genitalia: Tegmen ( Fig. 53 ) evenly convex (boat-shaped), parameroid lobes slightly pointed apically, dorsal sinus about one-quarter tegmen length, ventral sinus as long or slightly longer, sinuses internally with a complex of sclerites (unique among tegmina studied in this revision), meeting of tegminal arms and apodeme gradual, apodeme notably narrow, about one-quarter tegmen length; median lobe as in Fig. 90 .

Etymology. The specific epithet reduncus (from Latin ‘red-’ meaning back, and ‘uncus’ meaning hook), coined to mean curved backwards, refers to the RP vein of the hindwing, which is characteristically incurvate.

Biology. Collected from September to April by means of flight intercept and Malaise traps or caught at light. Habitat types: Eucalypt grassland; Acacia and eucalypt shrubland.

Distribution (Map 5). This widespread species has been collected in all mainland states and in all ecoregion types with the exception of alpine environs.

Remarks. Tegminal differences alone (compare Figures 52 and 53 ) support elevation of Opilo abdominalis , described by Schenkling (1901) as a variety of Opilo congruus , to full species status. As the available name Opilo abdominalis Fairmaire, 1891 has priority, and as this revision places Schenkling’s species in the new genus Notopilo , we propose the replacement name Notopilo reducnus rev. stat., nom. nov. for Opilo abdominalis Schenkling, 1901 .
