( Figs. 59 , 86–87 , 132 , 142 , 179 , 187–188 )

Deretaphrus analis Lea, 1898: 547 . Blackburn 1903: 120; Carter and Zeck 1937: 200.

Diagnosis. This species can be readily distinguished from congeners by the nearly smooth body surface, the clearly interrupted pronotal median longitudinal canal with the posterior canal rounded and closed at the base, the densely setose antennae and tarsomeres, bearing setae that are longer than the segment from which they arise, the distinct shape of the submentum, the presence of two depressions on either side of the midline at the apex of abdominal ventrite V resulting in a median V-shaped area near the posterior margin, and genitalic characters. This species is most similar to D. piceus but can be distinguished by the nearly impunctate pronotum and the elytra and pronotal median longitudinal canal distinctly rounded and closed at both ends.

Redescription. Length 5.4–11.2 mm. Width 1.4–3.0 mm. Body elongate, parallel, dark brown to black; dorsal surface glabrous, matte to moderately shiny; ventral surface moderately shiny, glabrous except for minute setae that arise from punctures. Head: In dorsal view, slightly narrowed anteriorly; without laterally expanded supra-ocular ridges; eyes visible from above; punctures minute and dense except sparse along posterior margin. Frontoclypeal suture distinct, arcuate anteromedially. Anterior margin of clypeus broadly arcuate. Submentum shape as in Fig. 51 ; distinctly separated from subgenal braces, with paired setose pits; anterior margin slightly expanded anteroventrally over oral cavity, at least part of mentum visible. Antennal groove well-developed, impunctate. Antenna densely setose; segment 1 with few setae on ventral surface; segments 2–4 with short setae; segments 5–11 with long, golden setae that are longer than and extend beyond distal margin of antennal segment from which they arise. Antennal club segments with multiple transverse rows of setae. Antennal club subsymmetrical. Dorsal surface (external face) of mandible with median setose groove. Thorax ( Fig. 59 ): Pronotum elongate, widest near anterior ¼; dorsal surface flattened along longitudinal midline, convex laterally; anterior margin arcuate, slightly wider than head; anterior angles rounded; base narrower than elytral bases; posterior margin moderately sinuate; posterior angles with small denticle; lateral margin with incomplete carina, forming a distinct raised border in dorsal view. Pronotal disc smooth, with minute, sparse punctures. Pronotal median longitudinal canal well-developed, interrupted to form a deep, anterior fovea and a posterior canal; raised interruption of the canal impunctate; posterior canal wide, deeply impressed, rounded and closed at the base. Hypomeron minutely punctate; strongly deflexed medially. Prosternum flat medially, strongly deflexed at lateral margin. Tergosternal suture slightly sinuate. Elytra ( Figs. 86–87 ): Elytron convex. Elytral surface smooth, punctures weakly impressed, nearly indiscernible; interstitial intervals 3, 5, 7, and 9 feebly raised, more pronounced near apex. Interval 5 meets or nearly meets interval 9 near apex. Intervals 3, 5, and 7 with micropunctures at crest. Apical elytral margin with small, dense punctures. Basal elytral margin with intervals 3 and 5 each ending in a knob-like protuberance; protuberance of interstitial interval 5 merges with finger-like callosity on the elytral shoulder. Legs: Base of femur and trochanter with long, sparse setae; inner face of tibia with fringe of long, dense setae. Tarsus densely setose with long setae that extend beyond the segment from which they arise. Abdomen: Abdominal ventrite V more heavily punctured, bearing two depressions on either side of midline, resulting in a raised, median V-shaped area near posterior margin ( Fig. 132 ), present in both sexes. Aedeagus: Phallobase as in Fig. 142 . Tegmen consisting of paired, elongate, anteriorly-projecting subtriangular plates at middle; plates narrowly touching medially. Basal piece with long anterolateral struts; struts recurved anteriorly. Parameres broadly rounded, broadly fused to one another near base, collectively articulated to phallobase; each paramere with a pair of oblique, elongate-oval patches near base and a pair of suboval patches near apex; patches lighter in color than remainder of paramere; paramere sparsely setose with short setae at apical margin; dorsal surface of paramere lacking process; Penis similar to Fig. 167 ; elongate, slender, variously curved; apex narrowed and pointed; base slightly expanded, bearing long, slender, paired anterior struts. Penis slightly lighter in color near base.

Variation. Deretaphrus analis varies in coloration from light reddish orange to pitchy black. The shape of the anterior portion of the pronotal median longitudinal canal ranges from elongate to teardrop-shaped to oval. The pronota range from slightly to moderately narrowed near the base. In some specimens, the elytral punctures can be seen, but in most the punctures appear absent.

Distribution. Australia: New South Wales and Queensland ( Fig. 179 ).

Biology. One specimen was collected under the bark of Acacia sp. Another specimen was collected by fogging vine scrub with pyrethrum.

Remarks. Lea (1898) did not mention the number of specimens examined. No specimens from Tweed [River?] were examined; however,

three specimens from Richmond River were cardmounted together. In order to stabilize this name, a lectotype and two paralectotypes are here designated from the syntype series of Deretaphrus analis . The lectotype and paralectotypes are mounted on the same card mount and pin. The specimen on the left is the lectotype [ SAMA 279 NL]. The middle specimen [ SAMA 280 NL] and right specimen [ SAMA 281 NL] are paralectotypes .

Type Locality. Tweed and Richmond Rivers , New South Wales .
