description: Melittommatinae, Wheeler, 1986
The subfamily Melittommatinae was proposed by Wheeler (1986) for those members of the family Lymexylidae in which the elytra completely conceal the abdomen or expose at most two abdominal terga, and the larvae have a heavily sclerotised, truncate tergite IX. The largest genus in this group is Melittomma, with about 20 species primarily in tropical and subtropical regions of both Western and Eastern Hemispheres. Other currently recognised genera include Melittommopsis Lane (1955), with at least four species from South America, the monotypic Protomelittomma Wheeler (1986) from the Seychelles and Madagascar and the Australian Australymexylon Wheeler (1986). The remaining fossil species, Ponomarenkylon alexandri Kirejtshuk (2008), an apparent Melittommatine from Baltic amber differ from other lymexylids in having: 1) very large eyes, (2) unusually short prothorax 3) filiform antennae and 4) the apparent connation of the first three abdominal ventrites (straight margins separating the first three ventrites and curved margins separating 3 from 4 and 4 from 5). Only a re-examination of the holotype will support or refute the author’s hypothesis.
More than 20 years ago, the genus, Alcestoma Fairmaire (1895) was transferred to Lymexylidae from Melandryidae in a supplement to a paper dealing with a portion of the beetle fauna of the Prioksko-Terrasny Biosphere Reserve in the Moscow Region, Russia (Nikitsky et al. 1998). Fortunately, Dr. Nikitsky photographed the types in his possession and sent me a habitus figure plus several detailed images. Based on these images, there is little doubt that this species is congeneric with Melittomma insulare Fairmaire (1893) from the Seychelles, which was made the type species of Protomelittomma Wheeler (1986).

Diagnosis. According to Wheeler (1986), adults of the genus Melittomma may be distinguished from other members of the family by having large, often proximal eyes, palp organs in the male, entire or almost entire elyra, appendiculate paratergites on abdominal segment IX and small parameroids, while lacking setose pads on segment VIII in the male. Larvae may be distinguished by the presence of a heavily sclerotised abdominal apex terminating in a concavity lined by a deeply notched ridge. Adults of Australymexylon species differ in lacking palp organs and having setose pads on segment VIII in the male, while Alcestoma species lack the appendiculate paratergites on segment IX and have more elongate parameroids.
Note. The genus Melittomma currently contains about 20 species worldwide, but it is not clear if all of these species share the diagnostic features mentioned above. Wheeler (1986) moved M. insulare Fairmaire (1893) and M. curtipenne Pic (1939) to the genus Protomelittomma Wheeler (= Alcestoma Fairmaire) and considered them to be synonymous, but some Melittomma types were not seen and some names were based on females only. This problem can only be addressed by those with access to the relevant types. The only true Melittomma occurring in Australia, based on male genital and pregenital features listed above, is M. pervagum, which is redescribed below.

description: Atractocerinae Laporte, 1840
The Atractocerinae are unique among the Coleoptera in many respects, but notably in the extreme reduction of the elytra combined with the lack of transverse folds in the hind wings, which are almost completely exposed, lying over the abdomen. Based on the wing character alone, this subfamily was treated as a beetle suborder, Aplicalae, by King (1955); but Selander (1959) demonstrated that this wing type could be derived from that found in the lymexylid genus Melittomma. Likewise, Baehr (1976) in his detailed descriptive paper on the prothoracic morphology of “ Atractocerus sp.” commented on several structures (e.g., spinasternum, dorsal cervical sclerites, karepisternum, which “have been lost” in all other Coleoptera. Although this group appears to be derived from an ancestor well within the Polyphaga, the family Lymexylidae being part of or sister to the large superfamily Tenebrionoidea, the adult has certainly undergone major changes in body structure.
The ideas on relationships of atractocerines to other lymexylids have not really changed from those of Wheeler (1986), with the Palaearctic genus Lymexylon Fabricius as the sister group. It may be time, however, for a worldwide analysis to be performed based on adult and larval morphology and molecular data. This, however, is beyond the scope of the present study.
As noted in the Introduction, the subfamily now includes six extant genera: Arractocetus Kurosawa (1985), with ten species from Japan, Taiwan, Southeast Asia, the Philippines, India, Indonesia, New Guinea and the Moluccas; Atractocerus de Beauvois (1801), with eight species from Central and South America, the West Indies, tropical Africa, Madagascar, India, Sri Lanka, Sumatra and southern China; Fusicornis Philippi (1866), with a single species from Chile; Hymaloxylon Kurosawa (1985), with two species from India, Nepal and western China; Raractocetus Kurasawa (1985), with two species from India, the Philippines, Taiwan, Southeast Asia, Indonesia and Australia (introduced with Eucalyptus into New Zealand and Chile); and Urtea Paulus (2004) with one species from northern Greece. In addition, the following fossil Atractocerinae have been reported: Cretoatractocerus grimaldii WolfSchwenninger (2011), the earliest member of the group from the Lower Cretaceous (Upper Aptian) Crato Formation of Brazil, plus Vetatractocerus burmiticus Yamamoto,(2019), Raractocetus extinctus Yamamoto (2019) and R. fossilis Yamamoto (2019) from the mid-Cretaceous Burmese amber (earliest Cenomanian), R. balticus Yamamoto (2019) from mid-Eocene Baltic amber and Atractocerus sp. from Miocene Dominican amber (Yamamoto, 2019).

description: Arractocetus Kurosawa, 1985
Arractocetus Kurosawa, 1985: 112.
Type species: Atractocerus nipponicus Nakane, 1985 (original designation).
Diagnosis. Species of Arractocetus are distinguished from other atractocerines by the head, which is declined, flattened above and abruptly declined posteriorly, the head and pronotum densely clothed with hairs, the pronotum subquadrate with a distinct median groove, and the hind wings often darkened or metallic. Eyes in this genus are very finely facetted, with individual facets flattened rather than convex.
Distrubution. Arractocetus is primarily an Oriental genus, distributed from India to Southeast Asia, Indonesia, New Guinea, northern Australia, the Philippines, Taiwan and southern Japan.
Biology. As noted by Kurosawa (1985), the eye type in this genus is indicative of diurnal habits and the colour patterns appear to mimic those of various Hymenoptera.

Type species: Atractocerus necydaloides Palisot de Beauvois (monotypy) (= Necydalis brevicornis Linnaeus, 1766).
Diagnosis. Species of Atractocerus in the strict sense are characterised by the large, elongate eyes, elongate, horizontal head, which is narrower than the pronotum, and very short elytra.
Distribution. At least ten species of Atractocerus have been described from California to Brazil, Africa, Madagascar, India, Sri Lanka, Southeast Asia, Indonesia and northwestern Australia, but it is not certain that all of these species are congeneric. According to Kurasawa (1985), A. brevicornis (Linnaeus), A. reversus Walker and A. brasiliensis Lepeletier & Audinet-Serville belong to this genus, and A. crassicornis Clark should be added to this list.

Raractocetus

description: Raractocetus Kurosawa, 1985
Raractocetus Kurosawa, 1985: 111.
Type species: Atractocerus emarginatus Laporte, 1836 (original designation).
Diagnosis. Species of the genus Raractocetus differ from those of Arractocetus Kurasawa, Fuscicornis Philippi and Hymaloxylon Kurosawa and Leptonetron gen. nov. in having the eyes very large and contiguous (male) or subcontiguous (female) in frontal view. Raractocetus is distinguished from Atractocerus by the larger, shorter and more vertically oriented head, as wide as or wider than the anterior pronotal margin, more robust antennae and shorter elytra. A male from Barro Colorado Island, Panama fits the description of Atractocerus procerus Schenkling (1914) and has the head characters of Raractocetus, but A. procerus cannot be transferred to Raractocetus without examination of the type. If this specimen does belong to A. procerus, then the Neotropical species differs from both R. emarginatus and R. kreusleri in having a median groove behind the eyes and a median groove extending the entire length of the pronotum.

Coelostoma turnai Hebauer, 2006: 3.
Type material: not examined.
Material examined. HUNAN: 1 male, 30 km N of Dayong, Yanjiejie, 27–29.v.2005, Oto Nakládal leg (NMPC).
Diagnosis. Body size 4.5–5.0 mm. Prosternum finely carinate medially, with fine dentiform process anteromedially. Head, pronotum and elytra with similar punctation; elytra with lateral portion more strongly punctate, without traces of series of punctures laterally. Mesofemora densely pubescent except at extreme apex. First abdominal ventrite with recognizable median carina basally; fifth ventrite emarginate and with a row of stout setae apically. Aedeagus (Fig. 21). 1.0 mm long. Median lobe bottle-shaped with apex very deeply excavated (bilobed); gonopore situated basally, transversely oval; parameres slightly shorter than median lobe, sinuate on outer face subapically, apices truncate.
Remarks. When Hebauer (2006) originally described this species from Hubei, he stated that the prosternum is not carinate but bears a fine dentiform process anteromedially. The examined specimen from Hunan precisely agrees with the original description in all other characters including the morphology of the aedeagus and moreover also comes from southeastern China. We therefore assign it to C. turnai, despite the fact that its prosterum is finely carinate.
Biology. Unknown.
Distribution. China (Hubei, Hunan) (Hebauer 2006, this paper).
