Stelis Minima Schenck, 1859 (Hymenoptera: Apoidea: Megachilidae) - A Species of Wild Bee New to Polish Fauna

Abstract

S u m m a r yThe paper presents information on Stelis minima Schenck, 1859, a species of cleptoparasitic bee new to Polish fauna representing the family Megachilidae. Stelis minima. probably inhabits most of Europe except for the southern and northern parts of the continent. The species was also found in the southern part of Finland, where it reaches its northern range limit (ca. 62°N). During the years 2002-2006 four specimens of S. minima were collected in the Kraków-Częstochowa Upland (1 male) and Roztocze region (2 females and 1 male). All specimens were observed close to nests of probable host species of solitary bees -Chelostoma campanularum (Kirby, 1802) and Heriades truncorum (Lin n a e u s , 1758). The female of Stelis minima can be distinguished from other Central European species by the following characteristics: rounded head, clypeus about 1.5 times wider than its length, legs black, hind basitarsus almost parallel sided (not broadened on the distal part), distances between punctures on mesopleurae ca. as big as their diameter, posterior margins of metasomal tergites (T) black and without lateral bands of hair, T 1 or T 1-2 with small, lateral, yellowish white maculae; the maculae are sometimes absent. The male Stelis minima can be separated from other Central European species by the following characteristics: clypeus short (not covering mandibles), legs black, distances between punctures on mesopleurae and tergites T 4-5 ca. as big as their diameter, posterior margins of metasomal tergites black and without lateral bands of hair, T 1-2 or T 1-3 with small, lateral yellowish white maculae, posterior margin of seventh tergite with short mid-process, posterior margin of third sternite with triangular emargination in the middle, posterior margin of fourth sternite with a tooth-like, mid-process.

Wastelands: their attractiveness and importance for preserving the diversity of wild bees in urban areas

“…The names of species and information on their social behaviour (solitary, eusocial, cleptoparasitic), nesting sites (soil, hive, cavity), food preferences (oligolectic, polylectic), and body size (small < 8 mm, medium 8-15 mm, large > 15 mm) follow Banaszak (1993), Celary (1995), Scheuchl (1995), Schmid-Egger andScheuchl, (1997), Pesenko et al (2002), Pawlikowski and Celary (2003), and Michener (2007) (Online Table A2). For each group, the number of species, the number of individuals, the percentage contributions to the total, and Shannon's index of diversity were calculated.…”
