Type material. LECTOTYPE (here designated) ♁: Victoria: Type [circular label with red border] // Opilus congruus Newman Entomol 365 / 55.91 Pt. Philip [pale blue paper label, folded] // Opilus congruus Type Newm. Port Philip [white card label] // Opilus congruus Newman Entomol 365 [pale blue paper label, folded] ( NHML) ( Fig. 181 ).

Comment on lectotype designation: As Newman (1842) made no reference to specimens in his description, it cannot be assumed that the nominal species group na me, Opilo congruus , was based on a single specimen ( ICZN 1999: Recommendation 73F). The NHML ‘type’ must therefore be considered a syntype ( ICZN 1999: Article 73.2) and available for lectotype designation ( ICZN 1999:Article 74.1).We designate the aforementioned NHML specimen ( Fig. 166 ) as the lectotype of Opilo congruus Newman for the purpose of fixing it as the sole name-bearing type of that nominal taxon. Condition of lectotype: Clean, left fifth pro-tarsomere and claw missing, numerous pronotal and elytral setae rubbed off.

Comment on nomenclature: Several species have been erroneously erected under the genus Opilus Latreille (1806) rather than Opilo Latreille (1802) which has priority over the later, invalid, spelling. Following Article 11.9.3.2 of The Code ( ICZN 1999), which states that “a species group name is deemed to have been published in combination with the correct original spelling of the generic name, even if it was actually published in combination with an emendation or incorrect spelling of the generic name”, the genus component of the original species group name spelling of Opilus congruus (see Newman 1842: 365) is deemed an incorrect subsequent spelling of the genusgroup name Opilo Latreille. The combination Opilo congruus Newman, 1842 , is thefore recognised as the correct available name spelling.

Diagnosis. Pronotum evenly rounded laterally, disc not heavily punctate; elytra dark with orange fasciate and apical maculations (humeral maculae absent), fasciae meeting at suture, punctation lacking nodules ( Fig. 13 ), 8 th stria beginning before fascia, striae 1–3 and 8–10 not reaching apical maculae; femoral bases yellow, apical half (or less) dark, tarsi with three ventral tarsal pads. Notopilo congruus comb. nov. can be separated from N. reduncus stat. rev., nom. n. by its bicoloured legs and from N. confusus sp. nov. by its elytral punctation lacking internal nodules.

Redescription. Habitus: Fig. 166 . Total length: 7–13.1 mm (lectotype 10.02 mm). Head: Vertex, frons (including supra-antennal elevation), genae and submentum dark brown (gula often slightly paler), clypeus and antennae chestnut-brown (clypeus partly black along epistomal suture), anteclypeus transparent yellow/orange, labrum and palpi orange; eyes separated by 0.65–0.85 eye widths (lectotype 0.75); frons subtly raised and semiglabrous medially (variable), dense with shallow punctation laterally, punctations more widely separated nearer to vertex; genae and submentum wrinkled; ratio of exterior to interior edges of terminal palpomeres about 1.7:1 (maxillae) and 2.3:1 (labium); antennae reaching near base of pronotum; eyes and most of cranium vested with erect pale setae, frons with shorter medially-directed setae. Prothorax: Brown (slightly paler than frons), pronotal collar and arch paler; pronotum 1.15–1.26 times longer than wide (lectotype 1.2), sides round, widest just posterior of middle; subapical depression deeply v-shaped, disc with deep central sulcus (sulcus smooth, more open than linear), and baso-lateral semi-sulcate undulations, surface smooth in appearance, punctations small and occasional dorsally, slightly larger and denser laterally; 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 brown (similar shade to pronotal disc) with orange markings (each elytron with a large apical macula and a narrow weakly curved transverse fascia at the mid-length which touches the suture); length to width ratio 2.67– 2.96:1 (lectotype 2.82); mostly 10-striate, 8 th stria beginning between first and fifth punctation of 7 th stria, striae 1–3 and 8–10 end between fascia and apical maculae, punctation lacking nodules, large and complete anterior to fascia, smaller with posterior edge indistinct posterior to fascia, epipleurae extending well into apical curve, interstriae with very fine short semi-reclinate setae (>1 per puncture) and longer thicker erect setae (<1 per puncture), intrafoveal setae present (many setae rubbed from lectotype); hindwing with CuA 3+4 and CuA 1 cross-veins complete, MP 3+4 absent basad of CuA 1 crossvein. Legs: Femora yellow basally, light brown apically (apical half of profemora and one-third of meso- and metafemora), tibiae and tarsi light brown, ventral tarsal pads yellowish; profemora very slightly swollen, other femora slender. Abdomen: Ventrites orange. Male genitalia: Tegmen ( Fig. 7 , 52 ) very broad at ‘bend’ of tegminal arms with parameroid lobes long, narrow and tapering to a point, dorsal sinus just over onethird tegmen length, gradually narrowing then expanded near extremity, internal limit flat (not rounded), ventral sinus a little less than half as long as dorsal sinus, tegminal arms gradually meeting apodeme, apodeme just over quarter tegmen length; median lobe as in Fig. 89 ; pygidium as in Fig. 125 .

Variation. Many specimens blacker than brown; the frons can be lightly (as in the lectotype) or more heavily punctated and with, or without (as in the lectotype), a shallow central impression; the degree in curvature of the tegminal parameroid lobes differs slightly between specimens (though the overall form and proportions of components of the tegmen are consistent).

Biology. Collecting records for N. congruus span the entire year for Victoria and it has been collected in summer and winter in New South Wales and Queensland. Collecting methods include malaise and light trapping.

Distribution (Map 5). Temperate broadleaf and mixed forest ecoregions of Victoria, New South Wales and southeast Queensland; tropical moist broadleaf forests of far north Queensland; Mediterranean environs of coastal South Australia. Absent from Western Australia and the Northern Territory.

Remarks. Despite the abovementioned differences of the tegminal parameroid lobes and frontal sculpturing, the general form of the male tegmen, also elytral and pronotal form and sculpturing, are consistent in specimens from far north Queensland to southern Victoria. We therefore consider the specimens examined to constitute a single species.
