The Middle Triassic palaeontomofauna of Monte San Giorgio with the description of Merithone laetitiae (†Permithonidae) gen. et sp. nov
Full text linkThe Triassic is considered a crucial period for the establishment of the modern insect fauna and fossil records from this period are fundamental for understanding the real impact that the end Permian Mass Extinction events had on these animals. Here, we review the insect fossils from one of the main deposits of this period in the world, Monte San Giorgio, which is considered one of the nine main insect Fossillagerstätten. In this Lagerstätte, located on the border between Switzerland and Italy, a total of 273 fossil insects have been collected in five localities. The fossils found in Val Mara site D, one of the two richest insect fossils sites of Monte San Giorgio, present peculiar features, such as extraordinary sizes and phosphatisation of internal tissues revealing fine internal details. In contrast, the Val Mara site VM 12 fossil record (248 specimens) is dominated by small to medium size insects, usually almost intact, preserving details such as setae on wings and compound eyes. Besides these exceptional features, these fossil insects are of extreme evolutionary importance, since they represent the first or the last occurrence for their lineage. In this regard, their use to calibrate nodes in a phylogenomic dating analysis led to backdating the origin of many insect lineages, including Diptera and Heteroptera. Up to now, a total of five species from Monte San Giorgio have been formally described, belonging to the orders Archaeognatha (†Monura and Machilidae), Ephemeroptera, Hemiptera (Tingidae) and Coleoptera (Adephaga). A further species, Merithone laetitiae (†Permithonidae) gen. et sp. nov., whose fossil is included among the recent findings in Val Mara site VM 12, is described in the present work

Rediscovery of a lost semi-aquatic Leaf Beetle in the Hula Valley, Israel (Coleoptera, Chrysomelidae, Donaciinae)
Full text linkBetween 1951–1958, most of the Hula Lake and its surrounding swamps in the Upper Jordan River (Rift) Valley of Israel were drained with the supposed purposes to eliminate malaria and to reclaim land for agriculture; both reasons later proved to be unnecessary decisions. With the paucity of biological knowledge of the Hula region, especially its aquatic invertebrates, accurate assessment of the environmental damage from this drainage is still being realized. Based on natural history museum collection specimen records, the pre-drainage presence of some aquatic insect species has been verified. Among these was Donacia bicolora, a member of a semi-aquatic subfamily (Donaciinae) of Leaf Beetles (Chrysomelidae) and whose Israeli populations were thought to have gone extinct because of the drainage of the Hula and other locations. Recently this species was rediscovered in two populations. However, the molecular identification of two of these recently collected specimens from one population revealed that the identity of this species is actually Donacia simplex. In this work, the re-discovery of this species is detailed, and its conservation importance discussed
Smittia nudipennis
No full textSmittia nudipennis (Goetghebuer, 1913) Camptocladius nudipennis Goetghebuer, 1913: 166. Material examined. 1 pinned ♁ now mounted on slide, labelled: ‘ Camptocladius nudipennis, Coll. et det. Goetgh. M. Goetghebuer // Gand, 31.III.1914 ’. Comments. The hypopygium is lacking so the specimen cannot be confirmed to be S. nudipennis even if it cannot be excluded.Published as part of Magoga, Giulia, Montagna, Matteo, Marziali, Laura, Rossaro, Bruno & Disaa, 2017, Revision of type and non-type material assigned to the genus Orthocladius by Goetghebuer (1940 - 1950), deposited in the Royal Belgian Institute of Natural Sciences (Diptera: Chironomidae), pp. 723-749 in Acta Entomologica Musei Nationalis Pragae (Acta.

Hydrobaenus conformis
No full textHydrobaenus conformis (Holmgren, 1869) Chironomus conformis Holmgren, 1869: 42. Orthocladius obesus Goetghebuer, 1940: 60. Type material examined. Orthocladius obesus: HOLOTYPE: pinned ♂, now mounted on slide, labelled: ‘ Orthocladius obesus n. sp. // type ♂ / M. Goetghebuer // type locality Abisko Lapp Sved Thienemann 1939 // R.I.SC.N.B. 18.073 / Coll. et det. M. Goetghebuer’. Comments. The synonymy of O. obesus with H. conformis was already proposed by SAETHER (1976), even if the type material was probably not examined; the present examination of the holotype confirms the synonym.Published as part of Magoga, Giulia, Montagna, Matteo, Marziali, Laura, Rossaro, Bruno & Disaa, 2017, Revision of type and non-type material assigned to the genus Orthocladius by Goetghebuer (1940 - 1950), deposited in the Royal Belgian Institute of Natural Sciences (Diptera: Chironomidae), pp. 723-749 in Acta Entomologica Musei Nationalis Pragae (Acta.

Bryophaenocladius muscicola
No full textBryophaenocladius muscicola (Kieffer, 1906) Orthocladius muscicola Kieffer, 1906: 332. Material examined. 1 ♁ pinned, now mounted on slide, labelled ‘ Orthocladius muscicola, Kieff Coll. et det. M. Goetghebuer // Hockai, 1.VII.1920 // 817’. Comments. The specimen is not from the type locality. The hypopygium is lacking, but the wings with coarse points, squama with setae and the well-developed acrostichals suggest conspecificity with B. muscicola (Kieffer, 1906). It is non-type material so nothing more is here stated other that it belongs to Bryophaenocladius Thienemann, 1934.Published as part of Magoga, Giulia, Montagna, Matteo, Marziali, Laura, Rossaro, Bruno & Disaa, 2017, Revision of type and non-type material assigned to the genus Orthocladius by Goetghebuer (1940 - 1950), deposited in the Royal Belgian Institute of Natural Sciences (Diptera: Chironomidae), pp. 723-749 in Acta Entomologica Musei Nationalis Pragae (Acta.
