Abstract
The dorsolateral glands at the thoraco-abdominal junction in the Tingidae sensu Carayon 1962 (i.e., excluding Vianaididae) were described by Carayon (1962), who suggested that they are homologous to Brindley’s glands (known only in Reduvioidea and functioning as specific scent glands). The glands described by Carayon (1962) in Tingidae occur in both sexes and consist of two parts, i.e., a true gland composed of glandular cellulae, and the so-called ‘evaporarium,’ composed of more or less rounded alveolae; both parts are connected by several canaliculi. The function of the glands is completely unknown or even hypothesized; and they have never been used for classification (except by Carayon [1962], who excluded Vianaididae from Tingidae partly based on this character) or in phylogenetic analyses.
