A complex of morphological features of the genera Dictyonota Curtis, 1827, Kalama Puton, 1876 and Derephysia Spinola, 1837 (Heteroptera: Tingidae: Tinginae), inconsistent with the characters of the tribe Ypsotingini Drake et Ruhoff, 1965, is discussed. The common morphological features of these genera together with those of Acalypta Westwood, 1840, which do not correspond to the characters of Tingis Fabricius, 1803, as the type genus of the tribe Tingini Laporte, 1832, are presented. The data on the sex chromosome system X0/XX of these four genera, radically different from that of all the other 17 so far karyotyped Tinginae genera (XY/XX), are summarised. The closely related genera Acalypta, Dictyonota, Kalama and Derephysia are united in a tribe under the resurrected valid name Acalyptini [Acalyptaini; ICZN Case 3813, in press] Blatchley, 1926 according to the principle of priority (ICZN, Article 23). A diagnosis of the resurrected tribe Acalyptini based on morphological and karyological characters and an improved key to the genera Acalypta, Dictyonota, Kalama and Derephysia are given. Резюме. Обсуждён комплекс морфологических особенностей родов Dictyonota Curtis, 1827, Kalama Puton, 1876 и Derephysia Spinola, 1837 (Heteroptera: Tingidae: Tinginae), не соответству- ющих признакам трибы Ypsotingini Drake et Ruhoff, 1965. Представлены общие морфологиче- ские особенности этих родов и Acalypta Westwood, 1840, не соответствующие признакам Tingis Fabricius, 1803, типового рода трибы Tingini Laporte, 1832. Обобщены данные о половой хромосо- мной системе этих четырех родов (X0/XX), кардинально отличающейся от таковой всех других 17 изученных к настоящему времени родов Tinginae (XY/XX). Таксономически близкие роды Acalypta, Dictyonota, Kalama и Derephysia объединены в трибу с восстановленным валидным на- званием Acalyptini [Acalyptaini; ICZN Case 3813, in press] Blatchley, 1926 в соответствии с принци- пом приоритета (МКЗН, статья 23). Даны диагноз восстановленной трибы Acalyptini на основе морфологических и кариологических признаков и усовершенствованный ключ для определе- ния родов Acalypta, Dictyonota, Kalama и Derephysia.
