Abstract
The male of Hymenoepimecis japi (Hymenoptera, Ichneumonidae, Pimplinae) is described and illustrated. The specimen was collected in a modified web (cocoon web) of Leucauge roseosignata (Araneae, Tetragnathidae) made in a laboratory. Both, host and parasitoid were collected in Reserva Biológica Serra do Japi, located in Jundiaí, São Paulo, Brazil.
Highlights
Sobczak et al (2009) described Hymenoepimecis japi parasitizing females of Leucauge roseosignata (Tetragnathidae) Mello-Leitão, 1943. They observed that the larvae in the last instar are able to induce the host to build a very modified cocoon web, consisting of only three support axes with a closed hub where the larva attached to a line holds its cocoon in the modified web
The aim of this study was to describe the male of H. japi
Nine parasitized females of L. roseosignata with egg or larva attached to their abdomen in August and September of 2011 were collected along the edges of a subtropical forest in Serra do Japi (23° 13’ 52” S, 46° 56’ 8” W), located in Jundiai, the State of São Paulo, Brazil
Summary
The genus Hymenoepimecis Viereck, 1912 belongs to the Polysphincta genus-group (sensu Wahl and Gauld, 1998 or Polysphinctini sensu Townes, 1969) and has Neotropical distribution, occurring from Mexico to the South of Brazil (Gauld, 2000; Gauld and Dubois, 2006; Loffredo and Penteado-Dias, 2009; Sobczak et al, 2009).Hymenoepimecis are characterized morphologically by the presence of a pocket-like structure on the pronotum, mesopleuron with epicnemial carina vestigial or absent, and absence of the vein 3rs-m in the fore wing (Gauld, 1991). All species of the genus Hymenoepimecis, whose biology is known, are koinobiontes ectoparasitoids of spiders of the families Nephilidae (Fincke et al, 1990; Gonzaga et al, 2010), Araneidae (Gonzaga and Sobczak, 2007; Sobczak et al, 2009; Sobczak et al, 2012) and Tetragnathidae (Sobczak et al, 2009; Gauld, 2000; Eberhard, 2000a, b, 2001). Sobczak et al (2009) described Hymenoepimecis japi parasitizing females of Leucauge roseosignata (Tetragnathidae) Mello-Leitão, 1943. They observed that the larvae in the last instar are able to induce the host to build a very modified cocoon web, consisting of only three support axes with a closed hub where the larva attached to a line holds its cocoon in the modified web. The aim of this study was to describe the male of H. japi
