Martins, Andre Luis & Krinski, Diones, 2016, First record of the parasitoid Gonatopus flavipes Olmi, 1984 (Hymenoptera, Dryinidae) in Brazil's Amazon forest, Journal of Hymenoptera Research 50, pp. 191-196 : 192-193

Gonatopus flavipes Olmi, 1984

Gonatopus flavipes Olmi, 1984: 1752.

Note.

Only two female specimens were collected (Figs 2-5 ). They present the following diagnostic features:

Diagnosis.

Completely yellow testaceous except petiole black and metasoma partly brown (Fig. 2 ). Pronotum shiny, unsculptured, crossed by strong transverse furrow. Scutum shiny, unsculptured, laterally with two pointed apophyses (Fig. 3 ). Meso-metapleural suture obsolete (Fig. 2 ). Head with frontal line complete; occipital carina absent; OL (distance between the inner edges of a lateral ocellus and the median ocellus)/POL (distance between the inner edges of the lateral ocelli) = 1.5/1.0 (Fig. 4 ). Enlarged claw with one small subapical tooth and one row of six peg-like hairs. Segment 5 of protarsus with two rows of 22 + 12 lamellae (Fig. 5 ). Tibial spurs 1/0/1.

Material examined.

Two females: Brazil, PA, Novo Progresso , Florentino Farm, Upland rice crop, 7°08'41"S 55°22'43"W, 09.ii.2011, D. Krisnki, Pitfall traps (DZUP) .

Gonatopus flavipes was recorded for Argentina, Bolivia, Brazil (Piaui, São Paulo and Santa Catarina States), Costa Rica, Ecuador, Guadeloupe, Jamaica and Mexico ( Olmi and Virla 2014) (Fig. 1 ). In addition we record for the first time the presence of this species from Pará State, Brazil, in upland rice crop.

Therefore, considering the economic importance of rice crops in Brazil, we recommend careful monitoring in rice areas and studies on the biology, morphology and ecology of G. flavipes in different rice crops.

In addition, more studies are needed to assess the population fluctuation of this parasitoid in different rice varieties, mainly to investigate if this species can be used in the future for the biological control of Auchenorrhyncha ( Guglielmino 2002; Mita et al. 2012). In fact, research out of Brazil have reported the occurrence of Gonatopus species associated with important pests of rice ( Mita and Pham 2014).
