Abstract: New geolocated records of the invasive ant Linepithema humile (Mayr, 1868) are added to the previous references for the city of Madrid and its surroundings, and the possible causes of the occurrence and permanence of this species in urban areas are discussed. The data collection corresponds to a series of samplings carried out for the last three years in green areas of the city, bibliographic searches, citizen science platforms and personal communications. To date, eleven locations in the urban area of Madrid and four points outside the city have been registered. The city of Madrid is undergoing a colonisation by the Argentine ant, although it is not widespread yet, since observations over time and space are isolated and apparently unrelated. However, this species has a great capacity to disperse and establish new colonies, mainly human-mediated through the transport of goods, plants, gardening tools, etc. Considering the numerous colonizable urban green areas in the city that can provide the necessary conditions for its expansion, the Argentine ant should not be underestimated, and immediate action is strongly recommended.

Nest structure, pollen utilization and parasites associated with two west-Mediterranean bees (Hymenoptera, Apiformes, Megachilidae) nesting in empty snail shells https://jhr.pensoft.net/article/49579/ Journal of Hymenoptera Research 76: 113-125

DOI: 10.3897/jhr.76.49579

Abstract: Around thirty species of European solitary bee species in the family Megachilidae nest in empty gastropod shells. We surveyed this group of bees in semi-natural sites adjacent to almond orchards near Lleida (north-eastern Spain) and collected 35 Hoplitis fertoni and 58 Osmia ferruginea nests in shells of six snail species. We describe the nest structure and report the identity of pollens collected by the two bee species. Both species adjust the number of brood cells to the size of the shell and occasionally build intercalary (empty) cells. H. fertoni uses clay and O. ferruginea chewed plant leaves for building cell partitions and nest plugs. Most nests of both species were built in Sphincterochila candidissima shells. Analysis of the pollen of selected nests confirmed that H. fertoni is oligolectic on Boraginaceae (in our study all pollen was from Lithodora fruticosa) and O. ferruginea is a polylectic species (collecting mostly pollen from Cistaceae, Fabaceae, and Lamiaceae in our study area). Nests of H. fertoni were parasitized by five species, the golden wasp Chrysura hybrida, the cuckoo bee Dioxys moesta, the velvet ants Stenomutilla collaris and Stenomutilla hotentotta, and the bee-fly Anthrax aethiops; nests of O. ferruginea were parasitized by the sapygid wasp Sapyga quinquepunctata and A. aethiops. Except for C. hybrida these are newly recorded host-parasite associations. Our results confirm previous information and bring new findings on the ecology of both species.

Aspilota ajara sp. n. (Hymenoptera, Braconidae, Alysiinae), the first species of the genus Aspilota Foerster from caves https://jhr.pensoft.net/article/10067/ Journal of Hymenoptera Research 52: 153-162

DOI: 10.3897/jhr.52.10067

Authors: Francisco Javier Peris Felipo, Rafael Garcia Becerra, Sergey Belokobylskij

Abstract: Aspilota ajara sp. n., a new species of the A. miraculosa (fasciatae) species group with very short upper tooth, was collected in a cave on La Palma, Canary Islands, Spain. This is the first Aspilota species known to occur in caves as well as the first record of Aspilota for the Canary Islands. The new species is described, illustrated and compared with related taxa.

Dinotrema cavernicola sp. n. (Hymenoptera, Braconidae, Alysiinae), a new species of the genus Dinotrema Foerster from caves of Spain https://jhr.pensoft.net/article/4392/ Journal of Hymenoptera Research 41: 47-56

DOI: 10.3897/JHR.41.8606

Authors: Francisco Javier Peris Felipo, Sergey A. Belokobylskij, Kees van Achterberg, Toni Pérez Fernández

Abstract: Dinotrema cavernicola sp. n. was collected in two caves in Spain. This is the first Dinotrema species known to occur in caves. This new species is described and compared to D. affine (Fischer, 1973) and D. collybiae Munk & Peris-Felipo, 2014, species sharing a mid-longitudinal carina on the propodeum.
