Parasitism on Araneus venatrix (Koch, 1838) (Araneae: Araneidae) by Hymenoepimecis silvanae Loffredo and Penteado-Dias, 2009 (Ichneumonidae, Pimplinae) with description of male of the wasp

Abstract

The wasp Hymenoepimecis silvanae Loffredo and Penteado-Dias, 2009, was recorded parasitising females of Araneus venatrix. The male of H. silvanae is described and illustrated. Specimens were collected in the Parque Estadual de Intervales and Reserva Biológica Serra do Japi, both located in the state of São Paulo, Brazil.Keywords: Polysphincta, Hymenoepimecis, parasitoid of spider, host.

First record of egg sac predation on a wall crab spider Selenopidae (Araneae) by the wasp Camera lunavenatrix sp. n. (Ichneumonidae, Cryptinae)

“…The transport of prey items to pre-made nests was hypothesized to be a pre-adaptation for the evolution of social behavior (Evans 1957, Evans andShimizu 1996); as a consequence, such interactions have sparked much attention. Ichneumonid wasps from the Polysphincta group (Wahl and Gauld 1998) are koinobiont ectoparasitoids of various groups of spiders (Sobczak et al 2012a, 2014, Gonzaga et al 2015. Likewise, this has drawn much interest due to the phenomenon of host behavioral manipulation Sobczak 2011, Takasuka et al 2015).…”

Description of the male Hymenoepimecis japi Sobczak et al. 2009 (Hymenoptera, Ichneumonidae) parasitoid of Leucauge roseosignata Mello-Leitão 1943 (Araneae: Tetragnathidae)

“…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, 2000aEberhard, , b, 2001. During the last larval stage of some of these interactions, the larva of parasitoid induces the host to make a modified web, called "cocoon web" (Eberhard, 2000a(Eberhard, , b, 2001Gonzaga and Sobczak, 2007;Sobczak et al, 2009;Gonzaga et al, 2010).…”

Hymenoepimecis neotropica (Brues & Richardson) (Hymenoptera, Ichneumonidae, Pimplinae) parasitoid of Araneus omnicolor (Keyserling) (Araneae, Araneidae): first host record and new occurrence to Brazil

“…In Brazil, occur six species of the genus Hymenoepimecis, five of that with record of host. Hymenoepimecis bicolor (Brullé, 1846) attacks females of Nephila clavipes (Linnaeus, 1767) (Nephilidae) (Gonzaga et al 2010); H. sooretama Sobczak et al 2009 attacks females of Manogea porracea (C. L. Koch, 1838) (Araneidae) (Sobczak et al 2009), H. japi Sobczak et al 2009 is parasitoid of the spider Leucauge roseosignata Mello-Leitão, 1943 (Tetragnathidae) (Sobczak et al 2009), H. silvanae Loffredo & PenteadoDias, 2009, used as host the spider Araneus venatrix (Koch, 1838) (Araneae, Araneidae) (Sobczak et al 2012) and H. jordanensis , with host unknown. H. veranii Loffredo & Penteado-Dias, 2009, is known as parasitoid of Araneus omnicolor (Keyserling, 1893) (Araneidae) (Gonzaga & Sobczak 2007) and Araneus orgaos Levi 1991 (Araneae, Araneidae) (Sobczak, unpublished data).…”
