description: Grotea claudiae Kumagai sp. nov.
(Figs 2A–F)
Type locality. Brazil, Pará, Parauapebas (Carajás National Forest).
Diagnosis
Frons between toruli and eye with a crest that border dorsally the dorsal tentorial pit. Pronotum mediodorsally with a transverse crest. Hind wing with nervellus intercepted before middle. Tergite I anteriorly squared in cross section, with dorsal and lateral faces forming a right angle.
Description (Holotype Female, pinned). Body smooth, with shiny and short hairs
Head subglobose, in dorsal view with gena behind eyes flat; in frontal view 0.7× as high as wide. Occipital carina complete, slightly raised on all its length. Lateral ocellus separated from eye by 1.2× its own maximum diameter. Compound eyes with a clear invagination at level of toruli; in frontal view 0.5× as wide as high. Frons laterally between toruli and eye with a crest that border dorsally the dorsal tentorial pit. Malar space 0.5× as long as basal mandibular width. Groove between clypeus and face strong. Clypeus 3.4× as wide as high medially, apically concave. Labrum exposed, semicircular, sclerotized as clypeus, densely pilose. Gena close to the junction of occipital and hypostomal carinae projected into a lamella that projects centrally below head. Antenna with 23+ flagellomeres; flagellomere I 1.17× as long as flagellomeres II and III combined.
Mesosoma 4.1 mm long, 1.1× as long as tergite I. Pronotum with anterior margin impressed and strongly reflexed, turned backwards as a small flange along its lateral portion; mediodorsally with a transverse crest; epomia absent. Mesopleuron with epicnemial carina complete, ending at 0.15 of lower corner of pronotum. Metapleuron slightly convex; submetapleural carina complete; juxta-coxal carina absent. Propodeum with area basalis 1.15× as long as wide and tapered posteriorly; anterior transverse carina weakly indented centrally; propodeal spiracle elongate; pleural carina complete; posterior transverse carina centrally absent; areas apicalis, superomedia, dentipara and postero-externa contiguous; lateral longitudinal carina anteriorly absent, so area spiracularis confluent with area externa; area juxta-coxal quadrangular, about as long as broad. Hind coxa as long as femur. Fore wing 9.6 mm long; crossvein 1cu-a opposite to M&Rs; postnervulus straight, intercepted at middle. Hind wing 6.4 mm long; with 11 basal hamuli on tubular vein C; and 6–7 distal hamuli on vein RA, forming a proximal cluster with the first 2 hamuli and with the others equally spaced; nervellus with CU 0.36× as long as cu-a.
Metasoma. Tergite I 3.75 mm long, very slender, about 0.9× as long as mesosoma, curved upwards posterior to 0.6 of its length, with spiracle on 0.34 of its length. Tergite I anteriorly squared in cross section, with dorsal and lateral faces at right angle. Exposed portion of ovipositor 6.0 mm, about 2.0× as long as hind tibia.
Coloration. Body mostly yellow and black. Head mostly yellow; mandible teeth, irregular spot connecting toruli and anterior ocellus, transverse band connecting eyes to stematicum, antennae (except scape ventrally), gena dorsally and near occipital carina, and occiput black. Mesosoma mostly yellow; pronotum latero-posteriorly black; mesoscutum mostly black with V-like yellow spot; scuto-scutellar groove and axilla black; mesopleuron with black spots around epicnemial carina and below speculum; metapleuron anteriorly and inferiorly black; anterior half of metasternum black; propodeal areas basalis, externa and lateralis black. Fore leg yellow, except apical half of femur posteriorly brownish; claws brown. Mid leg yellow; coxa posterior side spot at the base, and basal half of trochanter dark brown; femur light brown posteriorly; basal third of tibia brownish; tarsi I–III dark brown with yellow apex, tarsi IV–V and claws dark brown. Hind leg with coxa yellow at base and apex, centrally with light brown patch apically bordered with black; trochanter black except apical border yellow; femur basal half light brown, distal half black with yellow apex; tíbia mostly brown except yellow apex, and yellowish spot in the middle of brown area; tarsi I–III dark brown with yellow apex, tarsi IV–V and claws dark brown. Wings hyaline with brown pterostigma. Metasoma mostly yellow; tergite I black with longitudinal lateral stripes near middle and posterior margin yellow; sternite I brownish, darkening towards anterior margin; tergites II–VII with anterior half dark brown; tergite VIII dark brown with extreme posterior margin yellow. Ovipositor sheath black; ovipositor brown.
Remarks. Grotea claudiae sp. n. resembles G. manausi in color of abdominal tergites and hind wing nervellus intercepted before the middle, although it lacks the fore wing distal brownish spot. Both G. claudiae and G. paulista have tergite I anteriorly square in cross section, but they can be easily distinguished by color pattern and wing venation.
Male. Unknown.
Etymology. The species is named after Claudia Maria Jacobi, biologist, Professor at Universidade Federal de Minas Gerais, who was a dear friend.
Distribution. Grotea claudiae sp. n. is described from Brazil, Pará state.
Material examined. Holotype (♀). Brazil, Pará, FLONA Carajás, (S11B- Malaise /campo, 06º21’35”S; 50º23’25”W, 734m.), 21–28.iv.2010, Kumagai / Lopes / Lima / Fonseca col. [1 ♀, CCT-UFMG-IHY-2204329].
Holotype condition. Missing flagellomeres 16+ in the left antenna and 23+ in the right antenna. Apart from that it is in good condition.
