Potter wasps (or mason wasps) belong to the subfamily Eumeninae of the family Vespidae.  It is a widely distributed subfamily which includes about 3,000 species in more than 150 genera (Brothers & Finnamore 1993).  The adults are small to large (7-28 mm) and compact to elongate with a sessile to strongly petiolate metasoma.  They are easily recognized by the following combination of characters: mesoscutum with a posterolateral projection known as parategula (Fig. 1); tarsal claws bifid; hind coxa with a longitudinal dorsal carina or folding (Fig. 2), often developed into a lobe or tooth and forewing with three submarginal cells. All the known eumenine species are predators; most of them solitary mass provisioners, though some isolated species show primitive states of social behaviour and progressive provisioning. Adult feeds on nectar.

The knowledge of Indian potter wasps is scanty and fragmentary. The important work available on Indian potter wasps is by Bingham (1897).  Van der Vecht (1937, 1959, 1961, 1963, 1981) made some important contribution. Recently, Gusenleitner (1996, 1998, 2001, 2006, 2008) also contributed to Eumeninae of India.  Note worthy contributions to the taxonomy of potter wasps of India are by Chhotani & Ray (1975), Ray & Kundu (1985), Gupta (1997, 2003, 2007), Ray (2000, 2003), Lambert & Narendran (2002), Lambert (2004) and Lambert et al. (2007, 2008).  In this paper, we present information on six genera and eleven species of potter wasps from Arunachal Pradesh, India, of which five genera and 10 species are new records for the state.  

 

Materials and Methods

Samples were collected by sweep net, killed by ethyl acetate and preserved as dry specimens.  The specimens were studied under Wild Heerbrugg Stereozoom microscope.  All the studied specimens are deposited at Arunachal Pradesh Regional Centre of the Zoological Survey of India, Itanagar (APRC/ZSI).
