Biology
Predatory. Adults can be beaten from dry branches or individually collected on fallen timber, where they hunt for other insects.
Distribution
Africa in the south of Sahara, eastern Asia (from India to Japan and Russian Far East), Australia: Queensland, New South Wales (types of Ancyrona aegra, Ancyrona amica, Ancyrona latebrosa, Ancyrona laticeps, Ancyrona vesca checked), New Guinea (including undescribed species). Strangely enough, one Japanese species, Ancyrona japonica, was introduced to Europe and first recorded in Hungary (“Visegrad 1904”). It has now been collected several times in adjacent Slovakia, on branches of decaying oak. Two Tertiary fossil species are known from European Eocene.
Species groups
In a review of Afrocyrona and Ancyrona, I divided the latter genus in several informal species groups (Kolibáč 2007b[2]). They are listed below together with a short diagnosis, although not all Ancyrona species are classified within the particular groups. This is only the first attempt to classify the rich and complex genus, so a monophyly of these groups should be checked and tried, then the groups may be established at the rank of subgenera).
lewisi species-group Species. Ancyrona lewisi, Ancyrona shibatai, Ancyrona haroldi, and numerous undescribed species from south and eastern Asia and New Guinea.
Distribution. Japan, China, southeastern Asia.
Diagnosis. Small, flat, broad, oval species. Dorsal surface with colour pattern formed by scales or rigid decumbent setae.
gabonica species-group Species. Ancyrona gabonica, Ancyrona ferrarii, Ancyrona vicina, Ancyrona bivittata, Ancyrona feai, Ancyrona incensa, Ancyrona martini, Ancyrona plana, and numerous undescribed species from eastern Asia and tropical Africa. Australian species Ancyrona aegra, Ancyrona amica, Ancyrona latebrosa, Ancyrona laticeps, Ancyrona vesca probably also belong to the group.
Distribution. Tropical Africa, south-eastern Asia and probably Australia.
Diagnosis. Extremely flat, broad, oval species without scales and lacking decumbent pubescence on dorsal surface; dorsal side quite bare or with inconspicuous or erect pubescence. Some species with longitudinal colour stripes on elytra; stripes not formed by pubescence or scales. Antennal club very loose, nearly serrate. Tegmen composed of two or three parts.
japonica species-group Species. Ancyrona japonica, Ancyrona diversa.
Distribution. Japan, northern China, Ussuri. Ancyrona japonica also spread to south-eastern and central Europe (from Bulgaria through Hungary to Slovakia); first European record in 1904.
Diagnosis. Rather elongate unicolorous species with long, soft pubescence on dorsal surface. Tegmen composed of 1 or 2 parts (parameral piece fused with phallobase), male abdominal segments IX–X more or less reduced.
colobicoides species-group Species. Ancyrona colobicoides, Ancyrona fairmairei, Ancyrona kosnovskorum (syn. fairmairei?), Ancyrona minor.
Distribution. Madagascar.
Diagnosis. Flat, elongate species with conspicuously elevate eyes and compact 3-segmented club. Yellowish elytra with dark black-brown pattern (stripes, spots), pubescence short and decumbent. Primitive tegmen composed of three parts. Elytra with distinct carinae. One specimen known to me from Madagascan copal (Cap d’Ambre).
endroedyi species-group Species. Ancyrona endroedyi, Ancyrona muellerae, Ancyrona caffra(?).
Distribution. South Africa.
Diagnosis. Body quite elongate (as in japonica group), with long, soft, erect hairs or short, decumbent, scale-like setae. Dorsal surface unicolorous or with pattern formed by pubescence. Radial cell completely or partly reduced. Tegmen composed of two or three parts. Elytra with more or less conspicuous carinae.
