Synonymized by  Blackburn 1903: 129.     Deretaphrus ericksoni: Blackburn 1903: 126, 130. Misspelling, no status.   Diagnosis.This species can be readily distinguished from congeners by the numerously interrupted elytral interstitial intervals near the apex forming multiple granulose denticles, abdominal ventrite V with a bulbous swelling near the posterior margin in females, the nearly glabrous antennae, the sub-quadrate pronotum, the pronotal disc with at most a weak median longitudinal depression, and the orange to reddish color. It most closely resembles  D. wollastoni. For comments on similarities and differences in relation to  D. wollastoni, see the diagnosis under that species.   Redescription.Length 6.3–8.5 mm. Width 1.7–2.4 mm. Body elongate, parallel, orange to dark red; dorsal surface moderately shiny, glabrous; ventral surface moderately shiny, with moderately long setae that arise from punctures. Head: In dorsal view, rounded anteriorly; with laterally expanded supra-ocular ridges; eyes partially concealed from above; posterior margin of eye meets a distinct strip of abruptly raised cuticle; punctures small and dense except sparse along posterior margin. Frontoclypeal suture distinct, straight medially, faintly impressed, suture darker than surrounding area. Anterior margin of clypeus slightly arcuate medially. Submentum shape similar to Fig. 50; short and transverse, distinctly separated from subgenal braces, without paired setose pits; anterior margin arcuate, inflexed medially, slightly expanded anteroventrally over oral cavity, palpi visible, mentum concealed; anterolateral angles rounded. Antennal groove well-developed, impunctate. Antenna appearing glabrous except under high magnification, segments 3–11 with a single transverse row of minute setae; setae on antennal club segments arising near the apex. Antennal club slightly asymmetrical, leading edge of club segments much more inflated than trailing edge. Sensilla on distal surface of antennal club segments not restricted to within cupules. Dorsal surface (external face) of mandible without median setose groove. Thorax( Fig. 64): Pronotum quadrate, widest near anterior ¼; dorsal surface strongly convex; anterior margin straight; anterior angles distinct; base narrower than elytral bases; posterior margin weakly sinuate; posterior angles with small denticle; lateral margin with incomplete carina, forming a distinct raised border in dorsal view, carina more distinct for anterior half, terminating anteriorly at anterior angles, before the true anterior margin of the pronotum. Pronotal disc with moderately large, dense punctures. Pronotal median longitudinal depression weakly developed, surface of pronotal disc only slightly depressed along midline, with no hint of anterior fovea; longitudinal depression slightly wider and deeper posteriorly, forming two small vague keels on either side of midline. Hypomeron large, less densely punctate than on pronotum, punctures slightly larger than found on pronotal disc; lateral walls nearly vertical. Prosternum convex medially, strongly deflexed laterally, before tergosternal suture. Prosternum gradually raised posteriorly, then depressed immediately anterior to procoxae. Tergosternal suture nearly straight. Elytra( Figs. 96–97): Elytron convex; interstitial intervals 3–9 shiny, raised from base until apical 1/3, then becoming interrupted into numerous prominent denticles or granules. Apical elytral margin rugose. Basal elytral margin with intervals 3 and 5 not ending in distinct knob-like protuberance; finger-like callosity on the elytral shoulder indistinct. Legs: Setation sparse; inner face of tibia glabrous. Ventral apex of tibia with 2 pockets of dense setae that arise on either side of the large, curved tibial spur. Tarsus sparsely setose except for 2 pockets of dense setae on the ventral surface at the apex of tarsomeres 1–3. Abdomen: Abdomen with moderately long setae. Ventrite V simple in males, bulbous swelling near posterior margin in females ( Figs. 134–135). Punctures on ventrite V smaller and denser than on ventrites I–IV. Aedeagus: Phallobase as in Fig. 147. Tegmen consisting of paired, subtriangular plates at middle; plates narrowly touching medially. Basal piece with short anterolateral struts; struts strongly curved anteriorly. Parameres moderately long, broadly rounded, well-separated and individually articulated to phallobase, internal lateral margins arcuate; paramere sparsely setose with short setae at apical margin; dorsal surface of paramere with moderately developed, subtriangular process; process evenly curved, narrowing anteriorly, slightly longer than 1/3 the length of the paramere, apex slightly swollen; processes widely separated, parallel medially. Penis similar to Fig. 169; short, moderately thick, more or less straight; apex narrowed and pointed; base slightly expanded, bearing short, paired anterior struts. Penis bicolored, lighter in basal 1/3.  Variation.The color varies from dark orange to dark red, and the surface luster ranges from matte to shiny. In some, the pronotal median longitudinal canal is slightly more impressed.   Distribution. Australia: New South Wales, South Australia, Tasmania, and Victoria( Fig. 177).   Biology.Several specimens were collected under the bark of  E. mannifera. One specimen was collected in a flight intercept window trough trap [ANIC 104NL].   Remarks.Neither Newman (1855) nor Reitter (1877)mentioned the number of specimens examined of  D. erichsoniand  D. granulipennis, respectively. In order to stabilize these names, lectotypesare here designatedfor  Deretaphrus erichsoniNewmanand  Deretaphrus granulipennisReitterfrom the syntypeseries of those species. There is a specimen in the Museum für Naturkunde, Humboldt-Universität zu Berlin[MNHUB 6NL, examined] bearing the label data: “ Tasmania// 1916 26 // ♀// PARATYPUS// Deretaphrus erichsonitasmanica Hze det. Dr. E. Heinze 1942”. This specimen was probably meant to be a paratypefor a subspecies (  D. erichsoni tasmanica), but no formal description was ever published by Heinze.     TypeLocality.  Deretaphrus erichsoni: Adelaide, South Australia;  Deretaphrus granulipennis: New South Wales.  Type Material Examined.  Deretaphrus erichsoni.  LECTOTYPE( Figs. 197–198) ( BMNH, cardmounted) label data: “Type [round label with orange border] // Adelaide [handwritten on blue round label] 54 / 70 [handwritten on underside] // Erichsoni Newman[in Newman’ s hand] // Acc.
