The Tok-tok beetles (genus ''Psammodes'') are ground-dwelling, Afrotropical beetles in the family Tenebrionidae. They are stout in shape and typically black or dark rufous in colour. They average about 2.6 cm in body length, but the Spindle toktokkie (''P. bertolonii'') has an elongate body shape and measures 5.3 cm, while ''P. sulcicollis'' reaches 6 to 8 cm, and is the largest Tenebrionid in the world. Like the related genus ''Dichtha'', the adults tap out a rhythm on the ground to attract and locate mates. Habitats are varied, from coastal forest to ridges, koppies, woodland and desert sand.〔 ==Species== The genus contains about 270 species, including: * ''Psammodes batesi'' Haag-Rutenberg JG 1871 (southern Africa) * ''Psammodes beccarii'' * ''Psammodes bertolonii'' Guérin-Méneville, 1844 – Spindle toktokkie (South Africa) * ''Psammodes blapsoides'' Haag-Rutenberg JG 1871 (Namibia) * ''Psammodes brunneus'' Olivier AG 1795 * ''Psammodes diabolicus'' Koch C2 (Namibia) * ''Psammodes fartus'' Péringuey LA 1904 (South Africa) * ''Psammodes grandis'' Solier AJJ 1843 * ''Psammodes gurannicus'' Lesne P 1922 (Kenya) * ''Psammodes hirtipes'' Laporte de Castelnau FLN 1840 * ''Psammodes kuisip'' Péringuey LA 1908 (Namibia) * ''Psammodes pilosiusculus'' * ''Psammodes pilosus'' Thunberg CP 1787 (Namibia) * ''Psammodes ponderosus'' Fåhreus OI 1870 (South Africa) * ''Psammodes scabratus'' Solier AJJ 1843 (South Africa) * ''Psammodes sellatus'' Haag-Rutenberg JG 1875 * ''Psammodes solieri'' Gebien, 1910 (South Africa) * ''Psammodes striatus'' Fabricius JC 1775 – Striped toktokkie (South Africa) * ''Psammodes sulcicollis'' Péringuey, 1885 * ''Psammodes terrenus'' Lesne P 1922 * ''Psammodes ventricosus'' Fåhreus OI 1870 * ''Psammodes vialis'' Burchell, 1822 (southern Africa) * ''Psammodes virago'' Koch, 1953 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Psammodes」の詳細全文を読む スポンサード リンク
