The family Scoliidae is a group of aculeate fossorial wasps with solitary habits and belongs to the superfamily Vespoidea of the order Hymenoptera.  Representatives of this family are robust, their body size varying from 5–35 mm, seldom up to 50mm, and are popularly called ‘hairy wasps’ or ‘hairy flower wasps’.  These insects are usually black and bear yellow, with red or white markings (spots or band).  Their wings are dark brown and show metallic or blue iridescence.  Males are slender than females and have longer antennae; often both sexes show variation pattern.  Though cosmopolitan in distribution, they are predominantly found in tropical regions.  Adult wasps are flower visitors and feed on nectar whereas their larvae are parasitoids of ground dwelling larvae of the family Scarabaeidae.  Bingham (1897) provided a consolidated account on Scoliidae fauna of the Indian subcontinent and recorded 53 species of true scoliids.  Later, this insect group was pursued by Betrem (1928), Jonathan & Gupta (1999a, 1999b, 2003), Gupta & Jonathan (2003), Gupta (2007), Kumar & Kazmi (2008, 2012), Kumar (2009a, 2009b, 2010), and Bhattacharjee et al. (2010).

The members of this family can be easily distinguished from other wasps in having: wings finely membranous apically and wrinkled (i.e., striolate) longitudinally; meso- and metasternum form a flat plate overlying the bases of the middle- and hind coxae, and propodeum divided into three by two longitudinal grooves passing through both disc and declivity (Krombein 1978).

Worldwide, this family is represented by about 300 species under 35 genera and two subfamilies (Proscoliinae and Scoliinae).  In India, 79 species under 13 genera in the subfamily Scoliinae have been reported till date.  From Maharashtra State, the scoliid fauna is represented by 10 species under six genera (Gupta & Jonathan 2003; Kumar 2010; Kumar & Kazmi 2012).

In this communication Scolia (Discolia) fasciatopunctata dunensis Betrem is reported for the first time from the Western Ghats, based on the specimens collected from Pune and Kolhapur districts of Maharashtra.  Before this, the subspecies was known from Delhi (I.A.R.I. Campus), Himachal Pradesh (Kangra), Odisha (Gopalpur), Uttarakhand (Dehradun, Chilla), Uttar Pradesh (Khurja), and West Bengal (Kolkata).  The species Scolia fasciatopunctata Guerin is represented by two subspecies which can be distinguished by the key. 



The scoliids were collected at different localities in Pune and Kolhapur districts of Maharashtra.  Both the districts are part of the Western Ghats of Maharashtra state.  All the specimens were captured by sweep net and killed by ethyl acetate and preserved as dry.  Later, the specimens were relaxed, properly spread and held on entomological pins (No. 2; size: 40x0.38 mm) for further taxonomic treatment.  The specimens were studied under a Lawrence & Mayo stereozoom microscope.  All identified specimens were labeled, duly registered and deposited at the Western Regional Centre of the Zoological Survey of India, Pune.  The nomenclature and identification is followed after Krombein (1978) and Gupta & Jonathan (2003).

Distribution: Delhi, Himachal Pradesh, Maharashtra (Pune & Kolhapur), Odisha, Uttarakhand, Uttar Pradesh and West Bengal.

A distribution map (Fig. 1) for S. (Discolia) fasciatopunctata dunensis in India is provided based on the published records and present collection made from the Pune and Kolhapur districts of Maharashtra.  The latitudinal distribution of this subspecies lies in the range of 160N320N latitude while its altitudinal range varies from 121172 m.




Diagnosis: Female (Image 1): Integument and vestiture black, abdomen with faint blue reflecting surface, third tergite with light to dark red band which may be narrow to broad, sometimes the band is interrupted or constricted in the middle.  Wings dark brown, with predominant blue reflections in white light. Length- 1622 mm.

Male (Image 2): Integument and vestiture black, abdomen entirely black with faint bluish to golden reflections.  Wings light brown, anteriorly darker, with coppery to purplish reflections.  Length 1215 mm.







Scolia (Discolia) fasciatopunctata dunensis is reported for the first time from the Western Ghats.  The present record extends its known geographical range significantly southwards from Delhi, Himachal Pradesh, Uttarakhand, Uttar Pradesh and westwards from Odisha, and West Bengal.  New areas need to be explored to find the occurrence of this subspecies in India.  Records of food plants and description of habitats of the subspecies will be important to understand its ecology.
