First report of Pseudimatidium pici (Staines, 2009), Coleoptera: Chrysomelidae: Cassidinae in ornamental palms from Paraguay. Investig. Agrar. [online]. 2023, vol.25, n.1, pp.46-48.

Paraguay reports several species of Coleoptera of the Cassidinae Subfamily that have plants from different families as hosts, as well as palm trees for industrial use as ornamentals. Ornamental palms occupy an important place in several landscape areas, being those of the genus Phoenix one of the most important from the aesthetic and economic point of view. In the first months of the year 2022, damage was observed in new palm leaves of the species Phoenix roebelenii, presenting a scratching of the mesophyll, the leaves acquiring ashen-brown stripes, with the consequent loss of aesthetic value. The inspection of these plants recorded the presence of a small beetle with a flattened dark brown body, which was identified as Pseudimatidium pici, Family Chrysomelidae, Subfamily Cassidinae.

Keywords : coleóptero; Cassidinae; Phoenix roebelenii; Pseudimatidium pici.
