Euglossa (Euglossa) monnei Nemésio View in CoL , sp. n.

Diagnosis. This species is assigned to the subgenus Euglossa (Euglossa) Latreille, 1802 due to its small size, short extended tongue, rhomboid metatibia, small and widely separated tufts on S2. It is also easily included within purpurea species group due to the subtriangular mesotibial tufts. Euglossa monnei sp. n. is very similar to the Amazonian Euglossa magnipes Dressler, 1982b , but both can be distinguished from each other due to the following characters: (i) shape of anterior mesotibial tuft, which lower lobe in Euglossa monnei sp. n. is proportionately larger compared to the upper lobe ( Fig. 9 View FIGURE 9 E) (smaller or similar in E. magnipes ); no other species of the purpurea group in the Atlantic Forest present the lower lobe of the anterior mesotibial tuft larger than the upper lobe, (ii) presence of an ivory marking on frontal surface of scape in Euglossa monnei sp. n. ( Fig. 8 View FIGURE 8 E) (absent in E. magnipes ), (iii) glandular scar of the metatibia shorter and wider in E. magnipes than in Euglossa monnei sp. n. ( Fig. 10 View FIGURE 10 E). (High quality photographs of holotype Euglossa magnipes can be found at Smithsonian Tropical Research Institute web site at: http://biogeodb.stri.si.edu/bioinformatics/roubik_bees/index.php?gs%5B%5D= magnipes (accessed October 27th, 2011 )).

Description (Male, Figs. 8 View FIGURE 8 E, 9E, 10E, 11E): Color and vestiture. Clypeus blue, rest of head bluish green, except the plain green inferior paraocular areas ( Fig. 8 View FIGURE 8 E); overall coloration of integument bluish green, except golden green in sterna ( Fig. 11 View FIGURE 11 E). Wings pale brown. Pubescence very sparse, predominantly fulvous hairs on metasoma and antennal sockets, black and fulvous hairs on mesosoma, black hairs especially on scutum. Ivory paraocular markings present and well developed, almost reaching malar area; anterior surface of antennal scape with large ivory marking.

Head. Width 5.0 mm; interorbital distance at level of antennal sockets 2.7 mm; maximum interorbital distance 3.0 mm; scape 0.9 mm; eye length 3.1 mm.

Body. Body length ca. 11.5 mm; anterior wing ca. 8.5 mm; tongue in repose reaching hindcoxa; scutellum 2.8 mm wide and 1.3 mm long; abdominal width 4.8 mm. Punctation on mesosoma dense, with circular punctures of approximately the same size, on scutellum dense, with larger circular punctures.

Legs. Foretibia and forebasitarsus fringed with medium-sized, dense, fulvous hairs; velvet area occupying all the ventral side of mesotibia, posterior mesotibial tuft small, slightly oblong; anterior mesotibial tuft subtriangular, lower lobe slightly larger than upper lobe forming a right angle with the latter ( Fig. 9 View FIGURE 9 E); metatibia oblong-rhomboid, inflated, post-glandular area fringed with medium-sized hairs (0.47 mm long).

Metasoma. Punctation on discal base of T1 sparse, with large circular punctures; on distal part of T1 and T2– T4 dense, comprised of small circular punctures; on T5–T7 dense, with large circular punctures. S2 with welldefined, widely separated tufts ( Fig. 11 View FIGURE 11 E).

Etymology. The specific epithet honors the “coleopterist” Miguel A. Monné.

Type locality. Holotype collected at Floresta Nacional ( FLONA) Rio Preto (18°21’28”S, 39°51’18”W, ca. 18 m a.s.l.), in the municipality of Conceição da Barra, state of Espírito Santo, southeastern Brazil, attracted to vanillin.

Attractive baits. Nine specimens were attracted to vanillin, four to cineole and a single male was attracted to trans -methyl cinnamate.

Geographic distribution ( Fig. 6 View FIGURE 6 ). Besides the type locality, Euglossa monnei sp. n. was collected at (i) RPPN Fazenda Michelin (Igrapiúna, Bahia); (ii) REBIO Una (Una, Bahia); (iii) RPPN Serra Bonita (Camacan, Bahia); (iv) PN Monte Pascoal (Porto Seguro, Bahia); (v) a non-protected forest fragment of ca. 300 ha in Itamaraju (Bahia); (vi) PN Descobrimento (Prado, Bahia), (vii) Reserva Natural Vale (Linhares, Espírito Santo), (viii) REBIO Sooretama (Sooretama, Espírito Santo).

It is important to notice that only 14 Euglossa monnei sp. n. males were recorded among ca. 15,000 orchid bees collected in all these areas. Although widely distributed in the core area of the so-called “Hileia Baiana” (the dense coastal Atlantic Forest of southern Bahia and northern Espírito Santo), this species is rare in orchid-bee samplings.
