description: Cladophorus Guérin-Méneville, 1830
Cladophorus Guérin-Méneville, 1830: Plate II, Fig. 9.
=Odontocerus Guérin-Méneville, 1838: 72 (a homonym of Odontocerus Stephens, 1829 (Trichoptera)) = Spacekia Strand, 1936: 169; Bocak 1998: 247 (an objective synonym of Metriorrhynchus Guérin-Méneville, 1830).
Diagnosis. Cladophorus is defined by long lamellae in male antennomeres 3–10, the characteristic shape of the wide, transverse pronotum, and the large, often brightly coloured body. The phallus reminds those of Cautiromimus Kleine, 1926, it is usually robust and short and, unlike Cautiromimus, does not have any clearly sclerotized part of the internal duct. The dissection of male genitalia is usually needed for the reliable identification. Metriorrhynchu s Gemminger et Harold, 1 869 has prolonged pronotum and internal sac with multiple thorns or spirally coiled sclerotized structure in internal sac (Bocak et al. 2006, Bocak 2007). Porrostoma Castelnau, 1838 and Ditua Waterhouse, 1879 differ in serrate male antennae (Bocak 2002).
Redescription. Body medium-sized to large, 10.1–16.1 mm long, often brightly coloured; pronotum uniformly yellow or black coloured, elytra often bi-coloured; seldom dark coloured body parts with blue metallic shine. Head slightly transverse, cranium without rostrum, eyes relatively small, hemispherically prominent. Male antennomeres 3–10 flabellate, lamella of antennomere 3 1.3 to 4.7 times longer than its stem, lamellae of antennomeres 5–8 regularly slightly longer, up to six times longer than stem of corresponding antennomere (Figs.
6–19), antennal lamellae attached to basal or apical part of stem; maxillary palpi 4-segmented, stout, apical palpomere securiform, labial palpi 3-segmented, similar in shape to maxillary ones. Pronotum transverse, with clearly marked seven areoles, wide and rounded anteriorly, sometimes narrowed frontally and with prominent anterior angles (Figs. 20–32). Scutellum flat, emarginate at apex. Elytra slender, wider and longer than abdomen, with complete four primary and five secondary longitudinal costae (Figs. 33–49), transverse costae dense, reticulate cells tiny, slightly to strongly transverse. Phallus usually stout, only C. haiaensis with very slender phallus, gradually acuminate apically, internal sac partly sclerotized, without thorns, phallobasal membrane pigmented and only partly sclerotized (Figs. 53–78). Ovipositor with moderately wide coxites; valvifers slender; vagina membranous with short spermaduct and gradually widened spermatheca.
Distribution. Australian Region: New Guinea, Yapen, Australia. The identity of the Australian species needs further investigation (see Introduction for details). All previous records outside these regions refer to other genera (Bocak 2002, Sklenarova et al. 2013, 2014).
