Colaphellus palaestinus Achard, a new leaf-beetle for Europe (Coleoptera, Chrysomelidae, Chrysomelinae)

Colaphellus palaestinus Achard, an alien invasive species is here reported for the first time for Europe. It was found for the first time in Malta in November 2017, and the year after thousands of individuals were observed in Malta with many photographs posted in social media and local news. Global distribution of this species and information on closely related species is also provided here. Colaphellus zarudnyi Medvedev is probably a synonym of C. palaestinus.peer-reviewe

Some techniques for the study of useful characters in the taxonomy of the genus Timarcha Samouelle, 1819 (Coleoptera, Chrysomelidae)

Historically the taxonomy of the genus Timarcha has been, and continues to be, quite confusing and largely erroneous. The confusion is mainly due to the absence of reliable traits that aid in precise identification; the lack of study of types at species-level has also contributed to the difficulty in the taxonomy. To improve this situation, we propose techniques for the dissection and study of three useful diagnostic characters such as the vestiture of the sole of female tarsi, and the morphology of the endophallus and its sclerites in males. These features combined are distinctive for each of the species and can help to resolve the taxonomy of the genus

Estudio del género Timarcha Samouelle, 1819: las especies del sur de la península ibérica (Coleoptera, Chrysomelidae)

The species of Timarcha Samouelle, 1819 living in the South of the Iberian Peninsula are reviewed basing on the available types. We have recognized twelve species-group taxa: Timarcha apricaria ssp. apricaria Waltl, 1835, T. apricaria ssp. heydeni Weise, 1882, T. apricaria ssp. parvicollis Rosenhauer, 1856, T. granadensis Bechynĕ, 1948, T. insparsa Rosenhauer, 1856, T. intermedia ssp. intermedia Herrich-Schäffer, 1838, T. intermedia ssp. lugens Rosenhauer, 1856, T. kiesenwetteri ssp. kiesenwetteri Kraatz, 1879, T. kiesenwetteri ssp. sagrensis Kuntzen, 1911, T. marginicollis Rosenhauer, 1856, T. scutellaris Waltl, 1835 and T. strophium ssp. carmelenae Petitpierre, 2013. Other two taxa studied here, Timarcha apricaria ssp. melitensis Weise, 1882 and T. strophium ssp. strophium Weise, 1888, are spread all around North Morocco (Rif) and Central-Eastern Spain (Cuenca and Teruel) respectively. The identity of the long-time unknown T. apricaria and T. scutellaris has been re-established. Timarcha heydeni, T. parvicollis and T. melitensis have been downgraded to a subspecific rank of T. apricaria, and T. carmelenae has been downgraded to a subspecific rank of T. strophium. Timarcha lugens is confirmed as a subspecies of T. intermedia, and T. kiesenwetteri ssp. sagrensis is tentatively maintained as a subspecies until more specimens will be available. The following new synonyms are proposed: Timarchaapricaria ssp. apricaria = T. coarcticollis Fairmaire & Allard, 1873, nov. syn. = T. paulinoi Kraatz, 1879, nov. syn. = T. parvicollis ssp. nitentula Bechynĕ, 1953, nov. syn. Timarcha apricaria ssp. parvicollis = T. seidlitzi Kraatz, 1879, nov. syn. = T. parvicollis ssp. elocata Bechynĕ, 1953, nov. syn. Timarcha apricaria ssp. melitensis = T. riffensis Fairmaire, 1888, nov. syn. Timarcha intermedia ssp. lugens = T. parnassia Weise, 1882 nov. syn. = T. nevadensis Fairmaire, 1884, nov. syn. Timarcha scutellaris = T. hispanica Herrich-Schäffer, 1838, nov. syn. = T. rugipennis Perez Arcas, 1865, nov. syn. = T. erosa Fairmaire & Allard, 1873, nov. syn. = T. vermiculata Fairmaire, 1880, nov. syn. = T. laevisterna Fairmaire, 1880, nov. syn. = T. transversicollis Fairmaire 1884, nov. syn. Timarcha strophium ssp. strophium = T. fossulata Bechynĕ, 1944, nov. syn. Timarcha splendida Pérez-Arcas, 1872 and T. sericea var. escalerae Kuntzen, 1911, are confirmed as synonyms of T. marginicollis Rosenhauer, 1856. Timarcha strophium Weise, 1888 has been redescribed basing on the types. The type series of Timarcha granadensis ssp. dislocata Bechynĕ, 1948 is made up by two species: one of them is T. granadensis; the other is a species from Central-Eastern Spain close to T. sobrina Fairmaire, 1884. Neotypes have been designated for Timarcha hispanica, T. intermedia and T. scutellaris. Lectotypes have been designated for Timarcha apricaria, T. erosa, T. granadensis, T. heydeni, T. insparsa, T. kiesenwetteri, T. laevisterna, T. lugens, T. melitensis, T. nevadensis, T. parnassia, T. parvicollis ssp. elocata, T. parvicollis ssp. nitentula, T. paulinoi, T. riffensis, T. rugipennis, T. seidlitzi, T. sericea, T. splendida, T. strophium and T. vermiculata. Timarcha apricaria Gistel, 1832 and T. angulicollis Motschulsky, 1849 are considered nomina dubia, and two species described as native of Andalusia, T. gravis Rosenhauer, 1856 and T. rugosula Rosenhauer, 1856, are alien to the Iberian faun

Description of fiv enew species and proposal of a new synonym in the genus Paropsisterna Motschulsky, 1860, from Australia (Coleoptera, Chryso-melidae, Chrysomelinae)

Five new species of Paropsisterna are described from Queensland, New South Wales and Western Australia, and a new synonym is proposed : Paropsisterna ambigua Daccordi, 2003, n. syn. for P. cernua (Chapuis, 1877). P. dogueti n. sp. is closely allied to P. delmastroi Daccordi, 2003 ; P. sergei n. sp. resembles P. angustipes (Blackburn, 1898) ; P. cooktowni n. sp. and P. fortepunctata n. sp. are related to P. purpureoviridis (Clark, 1864) ; P. fontaniva n. sp. belongs to the species complex of P. sexpustulata (Marsham, 1808). The species can be distinguished by the characters of the aedeagus.Description de cinq espèces nouvelles et proposition d’un nouveau synonyme dans le genre Paropsisterna Motschulsky, 1860, d’Australie (Coleoptera, Chrysomelidae, Chrysomelinae).
