Explotación oportunista del néctar regurgitado de una abeja (Rhodanthidium sticticum (Fabricius, 1787) (Hymenoptera: Megachilidae)) como recurso alimentario por Plagiolepis pygmaea (Latreille, 1798) (Hymenoptera: Formicidae)
[Opportunistic exploitation of a bee’s (Rhodanthidium sticticum (Fabricius, 1787) (Hymenoptera: Megachilidae)) regurgitated nectar as a food resource by Plagiolepis pygmaea (Latreille, 1798) (Hymenoptera: Formicidae)]
Joan Díaz Calafat
Opportunistic exploitation of a male Rhodanthidium sticticum (Fabricius, 1787) regur- gitated nectar as food resource by a worker of Plagiolepis pygmaea (Latreille, 1798) is reported. To the author’s knowledge, this is the first time that an exploitation of such re- source is described. It is discussed whether this is just a random event or part of the ant associative learning triggered by repeated conditioning through the territorial behaviour of the bee.
Lepisiota melas (Emery), una hormiga exótica más para la Península ibérica y dos adiciones a las hormigas de cataluña (Hymenoptera, Formicidae)
[Lepisiota melas Emery, a new exotic ant for the Iberian Peninsula (Hymenoptera, Formicidae) and two additions to the ants of Catalonia (Hymenoptera, Formicidae)]
X. Espadaler, Carlos Pradera, Roger Vila
The presence of Lepisiota melas (Emery, 1915), new to the Iberian Peninsula, in the facilities of the port of Barcelona is documented. The population is well established and coexists with at least seven species of native ants and one exotic. Two other species of ants are also added, one exotic (Paratrechina longicornis (Latreille, 1802)) and another native (Goniomma decipiens Espadaler, 1997) to the check-list of ants known in Catalonia.
Primer listado de hormigas (Hymenoptera: Formicidae) de la provincia de Cuenca
[First checklist of the ants (Hymenoptera: Formicidae) of Cuenca Province]
Aitor Alameda-Martín, J.A. Fernández-Martínez, Francisco Cuquerella Elorza
En este artículo se presenta el primer listado de hormigas de la provincia de Cuenca, que actualmente cuenta con 75 especies, repartidas en 22 géneros y 3 subfamilias. El listado se ha confeccionado con una exhaustiva revisión bibliográfica, que se ha completado con las 13 nuevas citas aportadas por los autores, a partir de muestreos realizados en Belinchón, Priego, Masegosa, Fuertescusa y Carrascosa de la Sierra.
Myrmecina graminicola (Latreille, 1802) is an endogeous species from the Western Palaearctic. In the Iberian Peninsula is widely distributed, specially in the northern forests. The Iberian samples fit perfectly into the accepted conception of the species. Larvae mor- phology is described in detail.
Formica picea Nylander, 1846 en la Península ibérica: estudio biométrico, nuevas citas y distribución
[Formica picea Nylander, 1846 in the Iberian Peninsula: biometrical study, new records, and distribution]
Fede García, Amonio David Cuesta-Segura, X. Espadaler
Formica picea Nylander, 1846 is a specialist ant of wet places. In the Iberian Peninsula, is known from few localities in the Pyrenees and the Cantabrian Mountains. We compile the few previous records and provide new locations for the species in Girona, León and Lleida provinces. The identification of Iberian samples as F. picea based on their biometry and other characteristics, as well as their distinction from the most similar species of the genus, is discussed.
