Mendesella yamadai sp. n. Bortoni & Penteado-Dias

( Figs 14 –16)

Material examined. Holotype female ( DCBU 17294 ) “ Luiz Antônio, SP, Brasil, Faz. Capão da Cruz, Armadilha Malaise, S 21°28'35" W 47°53'10", Mata Ciliar— 11.XII.2008, A.M. Penteado-Dias col.” . Paratypes: one male (DCBU 17297) “São Carlos, SP, Brasil, Universidade Federal de São Carlos , 16.X.1987, Armadilha Luminosa, A.S. Soares col.”; two females ( DCBU 184370, 184371 ) “ Jacutinga, MG , Brasil, Morro da Forquilha , S 22°21'40.5" W 46°35'28.2", 05.I.2010, Armadilha Malaise, C.R Araújo col.”

Description of female (holotype). Body length: 3.7 mm; Fore wing length: 3.2 mm.

Color. Head yellow orange except for scape laterally and ventrally, pedicel, flagellomeres, stemmaticum, ocelli and tip of mandible black. Mesosoma mostly yellow except for lateral lobes, basal median lobe of mesoscutum and tegula black. Legs yellow, except for inner side of apex of hind tibia and hind tarsus dark brown to black. Metasoma yellow. Ovipositor sheath brown.

Head. Entirely smooth. Antenna 37 flagellomeres.

Mesosoma. Mesoscutum smooth. Notaulus crenulate anteriorly and absent posteriorly. Propleuron smooth. Pronotum smooth with a weakly striate groove. Scutellar sulcus with seven carinae, scutellum smooth. Mesopleuron smooth. Metapleuron rugose. Propodeum strongly rugose with one areola narrow and nearly parallelsided, inside with some small transverse carinae.

Wings. Infuscate.

Legs. All legs smooth.

Metasoma. Apical width of first metasomal tergite 1.5 × basal width. Length of first metasomal tergite 1.7 × apical width. Hypopygium 2.0 × as long as wide. Ovipositor sheath as long as hind tibia. First metasomal tergite weakly rugose laterally with dorsal carinae narrowing about mid length, remaining parallel until end of tergum, remaining terga smooth.

Male. Body length: 3.7 mm. Fore wing length: 3.2 mm. Antenna with 33 flagellomeres. Hind tarsi with only inner side of basitarsus black, remaining yellow. Length of first metasomal tergite 1.75 × apical width.

Variation. Body length: 3.8 mm, Fore wing length: 3.2 mm to 3.3 mm. Antenna with 38 flagellomeres. Scape and pedicels entirely black mesonotum with a darker color pattern, hind tarsi color might be lighter than holotype.

Diagnosis. This species is closely related to M. jaraguaiensis as both species have the dorsal carinae of first metasomal tergite not diverging posteriorly, but differs in the length of ovipositor (1.5 × hind tibia for M. jaraguaiensis and 1.0 × hind tibia for M. yamadai ).

Biology. Unknown.

Distribution. São Paulo and Minas Gerais.

Etymology. This species is named after Magda Viviane Yamada, one of the authors of the description of M. jaraguaiensis .
