Abstract

Three new genera are described, providing valuable new information on the phylogeny and biogeography of the family Dermestidae: Derbyana, gen. nov., containing only D. matthewsi, sp. nov. from north-western Australia; Orphilodes, gen. nov., with three Australian species, O. australis, sp. nov. (type of the genus), O. minor, sp. nov. and O. malleecola, sp. nov.; and Trichodryas, gen. nov., with one described species, T. esoterica sp. nov., from the Malay Peninsula and undescribed species from the Sulu Archipelago, Sabah, Kalimantan and Java. A cladistic analysis is included based on a matrix consisting of the three new genera, exemplar genera representing all major groups of Dermestidae and outgroup exemplars from the families Eucinetidae, Derodontidae, Nosodendridae, Endecatomidae and Bostrichidae. Based on the results, a new supergeneric classification is proposed and compared with those in other recent works on Dermestidae and related groups. Recognised subfamilies and tribes include Orphilinae, Attageninnae, Thorictinae, Dermestinae (Marioutini and Dermestini), Megatominae and Trinodinae (Thylodriini and Trinodini). Trichelodini is suppressed and Hexanodes Blair is removed from synonymy with Trichelodes Carter. Keys are given to adults and larvae of the subfamilies of Dermestidae and the genera of Orphilinae, Dermestinae and Trinodinae.

Although Peacock (1978) synonymised this genus with Trichelodes Carter, the differences between adults of H. vulgatus and T. delicatula appear to be far greater than those separating other trinodine genera; thus, the two were coded separately for the analysis in order to test the monophyly of the combined taxon.

Appendix 2. Characters used in cladistic analysis

(1) Upper body surfaces: (0) not clothed with stiff, erect, dark bristles; (1) clothed with stiff, erect, dark bristles.

These bristles may also be dehiscent, with a narrowed base that is easily broken or bent; as a result they are often inclined in various directions.

(2) Head: (0) prognathous, not or only slightly declined; (1) moderately to strongly declined.

This refers only to the position of the base of the head relative to the prothorax; some prognathous heads may be strongly declined anteriorly, so that the mouthparts are ventral.

(3) Median occipital endocarina: (0) absent; (1) present.

This begins at the edge of the occipital foramen and extends anteriorly.

(4) Median ocellus: (0) absent; (1) present.

The median ocellus is coded as present in Hexanodes, although it may be very weakly developed, and absent in Trichelodes, which is certainly a secondary loss.

(5) Frontoclypeal region: (0) slightly to moderately, gradually declined; (1) strongly and abruptly declined.

(6) Mandibular base: (0) distinctly wider than antennal scape; (1) distinctly narrower than antennal scape.

(7) Mandibular apex: (0) bidentate; (1) unidentate or rounded.

(8) Mandibular mola: (0) present; (1) absent.

(9) Mandibular prostheca: (0) present; (1) absent.

The prostheca usually refers to a hyaline lobe, often lined with hairs, a brush of hairs or both, which lie immediately distal to the mandibular mola. Such a structure occurs in all mandibles with a mola (e.g. Derodontus, Nosodendron and Orphilus), but a similar structure, here considered as homologous, also occurs in several taxa that lack a basal mola (e.g. Dermestes, Derbyana, Mariouta, and Orphilodes).

(10) Mesodorsal edge of mandibular base: (0) without projecting brush; (1) with projecting brush.

(11) Galea: (0) much broader than subapical maxillary palpomere; (1) subequal to or narrower than subapical maxillary palpomere.

(12) Lacinia: (0) subequal in width to galea; (1) distinctly narrower than galea; (2) highly reduced or apparently absent.

In Thylodrias, the lacinia is a short, basal lobe that is clearly set off from the galea; in Trichodryas this lobe is fused to the base of galea. Only the latter has been coded as state 2.

(13) Inner edge of lacinia: (0) without acute, glabrous, hyaline lobe; (1) with acute, glabrous, hyaline lobe.

(14) Lacinial apex: (0) with uncus; (1) without uncus.

(15) Labial palp articulation: (0) exposed; (1) concealed by mentum.

(16) Corporotentorium: (0) present; (1) absent.

(17) Laminatentorium: (0) complete; (1) incomplete at midline; (2) absent (anterior arms not widened).

(18) Posterior pronotal angles: (0) obtuse or rounded; (1) more-or-less acute.

(19) Lateral portions of pronotal disc: (0) not tuberculate; (1) tuberculate.

(20) Base of pronotal disc: (0) without sublateral impressions or grooves; (1) with sublateral impressions or grooves.

(21) Pronotal disc: (0) without sublateral carinae; (1) with sublateral carinae.

(22) Pronotal hypomeron: (0) without impression or cavity; (1) with broad, shallow impression; (2) with discrete antennal cavity.

(23) Inner edge of pronotal hypomeron: (0) without narrow antennal groove; (1) with narrow antennal grove.

(24) Prosternum: (0) without or with narrow head rest; (1) with broad head rest.

The head rest is a shiny infolding of the anterior edge of the prosternum. It has been called the prosternal collar by Zhantiev (2000).

(25) Prosternal process: (0) complete, extending behind coxae; (1) incomplete or absent.

(26) Procoxa: (0) less than twice as long as wide, not or slightly projecting ventrally; (1) more than twice as long as wide, strongly projecting ventrally.

(27) Procoxa: (0) without distinct lamina or plate (may be carinate); (1) with distinct lamina or plate.

(28) Procoxa: (0) without secondary mesal articulation; (1) with secondary mesal articulation.

This secondary articulation involves a pair of lateral projections at the apex of the prosternal process, each of which fits into a notch near the procoxal apex.

(29) Protrochantin: (0) at least slightly exposed; (1) completely concealed.

(30) Procoxal cavities internally: (0) open; (1) closed.

(31) Base of scutellum: (0) not or only slightly or gradually elevated; (1) distinctly, abruptly elevated.

(32) Elytral epipleuron: (0) complete; (1) incomplete.

(33) Mesoventral procoxal rests: (0) absent; (1) present.

(34) Anterior edge of mesoventrite: (0) on same plane as metaventrite; (1) on different plane than metaventrite.

(35) Mesoventrite: (0) separated by sutures from mesepisterna; (1) fused to mesepisterna.

(36) Mesoventrite: (0) without cavity for reception of prosternal process; (1) with cavity for reception of prosternal process.

(37) Anterior portion of mesoventrite: (0) neither tumid nor carinate; (1) tumid or carinate.

This refers to the so-called body of the ventrite, as opposed to the mesoventral process, which extends between the mesocoxae.

(38) Mesocoxa: (0) without secondary mesal articulation of dermestine type; (1) with secondary mesal articulation of dermestine type.

This type of secondary articulation, which was first recognised by Lawrence and Newton (1995), involves a mesal impression near the apex of the mesocoxa and a lateral projection near the apex of the metaventral process.

(39) Mesocoxa: (0) without secondary mesal articulation of orphiline type; (1) with secondary mesal articulation of orphiline type.

This type of secondary articulation involves a mesal projection near the apex of the mesocoxa, which fits into the side of the mesoventral process near its apex.

(40) Mesocoxal cavities: (0) contiguous or separated by less than half the shortest diameter of a cavity; (1) separated by more than half the shortest diameter of a cavity.

(41) Metathoracic discrimen: (0) present; (1) absent.

(42) Exposed portion of metanepisternum: (0) moderately narrow (more than 3 times as long as wide); (1) very broad (more than 3 times as long as wide).

(43) Metacoxa: (0) strongly transverse; (1) slightly transverse; (2) more-or-less globular.

(44) Metacoxae: (0) separated by less than 0.25 times coxal width; (1) separated by more than 0.25 times coxal width.

(45) Lateral metacoxal articulation: (0) exposed or barely concealed by elytral epipleuron; (1) concealed by metanepisternum.

(46) Metacoxa: (0) meeting elytral epipleuron; (1) separated from elytral epipleuron.

(47) Metacoxal plates: (0) well developed and complete to lateral edge of coxa; (1) well developed mesally but absent laterally; (2) very weak or absent.

(48) Radial cell of hind wing: (0) well developed; (1) reduced and almost obliterated by pigment; (2) absent.

(49) Cross-vein r3: (0) strongly oblique, almost perpendicular to long axis of wing; (1) not or slightly oblique, more-or-less parallel to long axis of wing; (2) absent.

(50) Posterior radial vein: (0) not extending basally beyond mid wing; (1) extending at least to basal third of wing.

(51) Wedge cell of hind wing: (0) present; (1) absent.

(52) Number of free veins in medial field of hind wing: (0) five; (1) four; (2) three or fewer.

The presence of five free veins in the medial field (MP3, MP4+ CuA1, CuA2, AA3 and AA4) appears to be the primitive condition in this group, and possibly in all Coleoptera, owing to the fusion of the medial and cubital systems. Species of Attagenus and related genera may have an additional apical forking, so that there are six free veins. Since these are rarely found in both wings and may involve either MP3 or CuA2, they are considered anomalous.

(53) Anal notch of hind wing: (0) present; (1) absent.

(54) Mesotibia: (0) not or slightly expanded; (1) strongly expanded at or near apex.

(55) Outer edge of mesotibia: (0) simple; (1) crenulate; (2) armed with socketed spines and sometimes teeth.

(56) Tibial spurs: (0) well developed; (1) absent or reduced and not apparent.

(57) First meso- and metatarsomere: (0) not or only slightly shorter than second; (1) much shorter than second.

(58) First and second ventrite: (0) free; (1) more-or-less connate.

(59) Abdominal intercoxal process: (0) subacute to narrowly rounded; (1) broadly rounded to truncate; (2) absent.

(60) Sternite III: (0) not as long as IV and V combined; (1) at least as long as IV and V combined.

(61) Sternite III: (0) without pair of oblique grooves and pits; (1) with paired oblique grooves arising from deep pits.

(62) Sternite III in male: (0) without median patch of setae and glandular pores; (1) with median match of setae and glandular pores.

(63) Sternites V and VI in male: (0) without median patches of setae and glandular pores; (1) with median patches of setae and glandular pores.

(64) Apex of tergite IX in male: (0) not or shallowly emarginate; (1) deeply emarginate, tergite X distinct; (2) deeply emarginate, partly fused to tergite X; (3) completely fused to and indistinguishable from tergite X.

(65) Phallobase: (0) articulating with bases of parameres; (1) overlapping bases of parameres.

(66) Parameres: (0) not joined together dorsally; (1) joined together dorsally.

(67) Parameres: (0) not joined together ventrally; (1) joined together ventrally.

(68) Malpighian tubules: (0) free; (1) of modified cryptonephridial type.

The modified type of cryptonephridism is one in which all Malpighian tubules are reunited with the gut in a single bundle (Saini 1964). This is usually indicated in cleared dry specimens of bostrichoid adults by the presence of a rectal bar, which supports the perinephral sac. In adult dissections of Orphilus and Orphilodes species, the typical rectal bar could not be seen, although a light sclerotisation was present that could have been homologous to that structure. Orphilus was coded as having the modified type of cryptonephridism based on the illustration of the larval gut in Kiselova and McHugh (2005), whereas Orphilodes was coded as unknown for this character.

(69) Larva: body: (0) with sclerotised tergites; (1) without sclerotised tergites.

(70) Larva: body: (0) more-or-less fusiform; (1) C-shaped and grub-like.

(88) Larva: mandible: (0) more-or-less evenly pigmented; (1) heavily pigmented apically, lightly so basally.

(89) Larva: mandibular apex: (0) tridentate; (1) bidentate; (2) unidentate, acute; (3) unidentate, rounded.

(90) Larva: mandibular mola: (0) large, complex; (1) reduced, simple; (2) absent.

(91) Larva: mandibular prostheca: (0) present; (1) absent.

This hyaline lobe is distad of the mola, when present; however, in some mandibles lacking a mola, a similar lobe occurs just distad of the penicillus. This is considered to be homologous to the prostheca.
