Elateroidea

Campylomorphus homalisinus has been found on Mt. Lesima Northern Apennines and it is the first record for the Lombardy region. Campylomorphus elaterisae is a rare orophilous species: Little is known about the ecology of the species. This record and the expert-based investigation we performed determined that Campylomorphus homalisinus inhabits shrublands and grasslands, but may elaterida occur in the forests.

This survey includes the only record of Campylomorphus homalisinus foraging on flowers, a behavior that is not rare in the family Elateridae.

We hypothesize that adults integrate their diet with flower resources according to a generalist strategy. As a matter of fact, Elateridae are often sampled by aspiration on flowers Platia and Akrawi Due to unspecialized masticatory apparatus in comparison to others taxa like bees Coleoptera usually forage on disc and open flowers, where the resources are easily available Willmeralthough it is worth highlighting that they can cause damage to reproductive structures of flowers Leavitt and Robertson One of the less studied species is Campylomorphus homalisinus Illiger, It was named as Elater homalisinus by Illiger from a specimen from Portugal, but in Jacquelin du Val considered it as a monospecific genus.

Its larval stages and habits remain unknown Platia Moreover, the exact distribution of the species is uncertain. At present, online databases provide either poor information or no records at all.

Some historic works highlight the presence of the species in Italy, France and Iberian Peninsula Vamiliawithout giving details. Some ancient records of Deyrolle in Chevrolat refers to places by names which are not in use in modern times and therefore are not directly identifiable. Other records are biogeographically unlikely, for example a record at Mt. In the case of Mt. Such cases might be explained by incorrect identification Platia, in verbis.

It is really important to update the distribution of Campylomorphus homalisinus: In addition, changes in species range expansion or contraction might reflect response capability to a changing environment, and thus survival possibility. Species ranges and especially their dynamic are so important that the International Union for Conservation of Nature IUCN includes two criteria related to species biogeography in the process of assessing the threatened status of species: We have three questions about Campylomorphus homalisinus: Lesima Pavia, see Study area.

During the summer they were sampled weekly for 20 minutes, twice a day. In each sampling day the starting plot was chosen at random. The specimens have been identified by a specialist Dr. Historic records of Campylomorphus homalisinus have been verified with Museum collections and published works.

Zapata de la Vega have been interviewed about the ecology and the records of the species. With the purpose of assessing a possible sub-regional differentiation elateridad the altitudinal range of the species, the frequency of Italian records of Campylomorphus homalisinus above m has been calculated for the portion of its Italian distribution range to the west of Mt.

Lesima, and for the portion of the Italian distribution range to the east of the same mountain. The collection took place in a montane grassland formation with a north-eastern exposure and average altitude of m [Fig. This grassland is situated in the Lombardy side of Mt. Lesima m a. According to Rossetti and Ottonethe average rainfalls of the area that rounds Mt.

In the higher peaks, rainfall level is even greater considering both the orographic-lift effect in rainy clouds formations and the effect of moisture addition to air masses by daily heating, which is more frequent in the summer. The Temperate Oceanic Submediterranean bioclimate is the prevailing familiaa type in the mountainous area. Study area of Mt. Lesima Northern Apennines, Lombardy region, Italy. The star symbol shows the sampled grassland.

Above the altitude of famili vegetational stages of the series Trochiscantho nodiflori — Fago sylvaticae sigmetum are established, which are dominated by extended forests of Beech Fagus sylvatica Verde et al.

Some intermediate stages are dominated by mesophilous grasslands of the Festuco-Brometea typology, which are encountered mostly above m Verde et al. They are partly colonized by shrubs as Sorbus aucupariaRosa sp. Data collected on Mt. Lesima yielded the first record of Campylomorphus homalisinus Illiger, inside Lombardy Elateridaae [Fig.

A male specimen was recorded foraging on a flower Laserpitium silerApiaceae: Campylomorphus homalisinus of the picture was collected foraging on flowers of Laserpitium siler Apiaceae. It is not known whether this species has always been present elateridaw the area, but it is certain that it has not been detected in many surveys set in Lombardy Ruffo and StochMazzoldiVilla and VillaCavagna Sangiuliani Di Gualdana et al.

Additionally, records for Lombardy of this species are not present in the entomological collections of three Italian Natural History Museums: The hypothesis of an expansion northwards of the occupancy area should not be rejected. Indeed, 4 specimens of the species were collected in the nearby Mt. Antola Genova province, Liguria, stored in the collection of Natural History Museum of the University of Pavia, dated andwhich is only 15 km from Mt.

Elqteridae and has similar altitude and habitats. The distance between the most western record in France and the most eastern record in Spain is almost 10 3 km in straight line computed with GoogleEarth. Eastern distribution area of Campylomorphus homalisinus. Light green signs Italian administrative regions, yellow is the French one. Blue points sign occurrences of Campylomorphus homalisinus according to literature, databases and museums collections.

The red star shows mt. Western distribution area of Campylomorphus homalisinus. Red colour signs administrative regions of Spain, Portuguese ones are in orange.

Famlia can this discontinuous distribution be explained? During the Pleistocene era, ice-sheets extended their surface covering Central Europe several times. During glaciers expansions, species migrated towards southern not-iced refugia, namely the Iberian, Italian and Balkan Peninsulas.

During Earth’s warmer periods the glaciers receded and some species colonized the newly uncovered land. Some of them established continuous areas, like the mammal Erinaceus europeus Randi or the grasshopper Chorthippus parallelus Lunt et al. In Italy, Pedroni recorded a high proportion of Turanic species in the Northern Apennines Elaterid fauna and explained that as result of glaciers dynamics.

Might the discontinuous distribution of Campylomorphus homalisinus be explained in such a scenario? A continuous area of occurrence was probably present before the species took refuge in two different localized areas: However, after the glaciers receded, the species failed to occupy its previous area.

In fact, it is believed that colonization of central Europe post glaciations has been carried from extra-Mediterranean refugia because mountainous barriers like Pyrenees and Alps isolated the Mediterranean ones Randi This may be a reason why Campylomorphus homalisinus could not establish a continuous area after ice-sheet recession, having only taken refuge in the Mediterranean area.

Is it still the same species in both peninsulas? Platia states that specimens of the two distributive fanilia are morphologically identical Dr. Elaterridae, in verbis but a genetic analysis could help in validate such observation. In Italy and France, Campylomorphus homalisinus is orophilous, being present at altitudes between m and m CK-map database in Ruffo and Stoch In the Famikia Peninsula, such range is extended towards lower altitudes: Baselga and Novoa Thus, the altitudinal range differs between the two parts of the species’ range.

Our survey detected it on a flowered grassland of ha. In the Iberian Peninsula, records of Campylomorphus homalisinus are associated to Elateridae that elaterisae grasslands and shrublands like matorral Zapata de la Vega, in verbis. In Italy, Platia once recorded Campylomorphus homalisinus on the grassed top at a altitude of m a.

Catria, Platia in verbis without any trees. This situation is very similar to the studied area. Lesima the captured species were feeding on nectar Fig. Despite little available information, our observations on the ecology of Campylomorphus homalisinus suggest that clearings and grasslands are inhabited by the species, without excluding the presence in forests.

Data on the larval habitat are not available but it is possible that the larva inhabits forests, as it may live in the dead wood or underground humus Platia, in verbis. Finally, the female is very difficult to record 9 females out of 96 specimens have been collocated in G.

In the Ck-map database Ruffo and Stoch records of 22 elatdridae of Elateridae are present in 7 mountainous localities near the sampled grasslands Mt. Six others species inhabit either grasslands or clearings; also in this cases the usage of flowering plants resources is possible.

Thus, flower feeding is quite widespread in the Elateridae of this area: It is a surprisingly higher precentage than other areas: As highlighted by this sampling, by the other Elateridae fajilia in the area and according to the literature Arnett et al. In fact, pollination services are documented: The two plant species from which Elateridae were collected on Mt. Lesima have open flowers, but they differ in colour, presence of short tube and reward accessibility: Laserpitium silerwhich Campylomorphus homalisinus elatdridae Limonius minutus feed on, has disc white flowers with accessible nectar, grouped in umbrella-shape blooms; Knautia drymeiawhich Athous flavipennis feed on, has pink short tubular flowers grouped in head-blooms.

In the case of Elateridae resource usage of Mt.

Lesima is occurring a functional generalization sensu Ollerton et al. The authors would thank Dr.
