A new species viz., Stantonia hayati Ahmad, sp. nov., is described and illustrated from India, while S. hammersteini Enderlein, 1908 is recorded from Saudi Arabia. Affinities of the new taxa with related species have also been discussed. The genus Stantonia is also recorded for the first time from Saudi Arabia.

The genus Stantonia Ashmead belongs to one of the rarely collected subfamily Orgilinae of the family Braconidae. Members of Orgilinae are solitary koinobiont endoparasitoids of concealed lepidopteran larvae (Shaw and Huddleston, 1991). The known hosts of Orgilinae belong to the lepidopteran families of Coleophoridae, Gelechiidae, Tortricidae, Pyralidae and Oecophoridae (Shaw and Huddleston, 1991; Yu et al., 2016). Stantonia pallida Ashmead have been used in the classical biological control programme against Diaphania hyalinata and D. nitidalis, pests of cucurbit crops in USA (Frank and McCoy, 1993; Yu et al., 2016).

The genus Stantonia is nearly cosmopolitan in distribution with 75 valid species of which 31 occur in the Oriental region (Yu et al., 2016; van Achterberg et al., 2017). When compare Oriental fauna with India, the genus Stantonia regarded as poorly known group as it is reported by only a single species viz., Stantonia agroterae Nixon, 1950. The genus was revised by van Achterberg (1987; Indo-Australian spp.), Braet and Quicke (2004; worldwide), Chen et al. (2004; for China) and van Achterberg et al. (2017; for Vietnam, China, Japan, and Russia). In the present study one new species Stantonia hayati sp. nov., is described and illustrated from India and S. hammersteini Enderlein is recorded from southwestern region of Saudi Arabia.

Materials and methods

The specimens of new species were collected on light traps from northern Uttar Pradesh in order to study the biodiversity and conservation of parasitoid wasps in the northern region of India. Specimens from Saudi Arabia was also collected on light traps from Raidah Protected area which is one of the smallest wildlife reserves in the Kingdom of Saudi Arabia. Raidah is known as the “paradise” of Sarawat, which is the mountain range running parallel to the western coast of the Arabian Peninsula. It is an area of around 9 sq. km, located 20 km northwest of the southern city of Abha on the steep slope below Jabal

Saudah. The steep slopes of the region are densely covered with plants and trees, especially juniper trees, and there are several streams flowing from the height of the mountain and down to various parts of Raidah.

Terminology and identification

Sampling was done by means of light trapping. Photo of body profile was taken by a Nikon SMZ 1000 zoom stereomicroscope with attached camera. Measurements of the different parts were made with the help of an ocular micrometer fitted in Nikon SMZ stereomicroscope. Morphological terms, including wing venation, are based on van Achterberg (1993). Body sculpture terminology follows Harris (1979). Identification to the subfamily based on van Achterberg (1993), to the genus follows van Achterberg (1987) and the species level on Braet and Quicke (2004) and van Achterberg et al (2017). The type specimens of the new species are deposited in ZDAMU, while material pertaining to the new record from Saudi Arabia is housed in BDKKU.

Type material

Holotype, ♀: India: Uttar Pradesh, Aligarh: 24.X.2003 on light Coll. Zubair Ahmad (ZDAMU); Paratypes, 5 ♀ ,2 ♂, with same data as holotype (ZDAMU).


Female, holotype: Body length 3.00 mm; Forewing length 3.05 mm.

Head: Antenna 45 segmented; length of third segment as long as fourth segment; terminal segment 1.3x as long as penultimate segments; length of maxillary palp 2.2x height of head; length of eyes 2.3x as long as temple in dorsal view. OOL: AOL: POL: OD= 13: 3: 3: 6; vertex setose rather convex and punctulate; occipital carina interrupted medially; face rather flat and punctulate; clypeus punctulate; length of malar space about as long as basal width of mandible.

Mesosoma: Length of mesosoma about 2x its height; sides of pronotum crenulate medio-anteriorly and striate posteriorly.precoxal sulcus completely impressed and crenulate; rest of mesopleuron smooth but ventrally punctulate; mesoscutum punctuate to punctulate with hairs; notauli deeply impressed, complete and crenulate; scutellar sulcus deep with one carina; scutellum slightly convex and punctulate; surface of propodium coarsely reticulate rugose, anteriorly sparser than posteriorly. Forewing vein r: 3-SR+SR1=16: 82; 2-SR: r-m =22:12. Hind coxa punctate with few transverse carinae dorso-posteriorly; length of femur, tibia, and basitarsus of hind leg 87: 110: 103; hind tarsal claw rather robust; length of hind tibial spurs 0.45x as long as hind basitarsus.

The new species resembles with S. chaoi Chen et al., 2004 on the basis of its overall body coloration and nearly smooth ventral surface of hind femur. However, it differs from S. chaoi in having: frons yellowish (frons with pair of dark brown spots posteriorly in S. chaoi); median lobe of scutum dark brown (median lobe of scutum yellowish brown in S. chaoi); propodium coarsely reticulate rugose, anteriorly sparser than posteriorly (propodeum rugose medially and re­mainder nearly smooth in S. chaoi; length of forewing 3 mm (length of forewing 4–6 mm in S. chaoi); Vein r-m of forewing omitted comparatively low from vein 2-SR (Vein r-m almost omitted near connection of vein r and 3-SR+SR1 in S. chaoi).


India, Uttar Pradesh.

Host record



The new species is named after Dr. Mohammed Hayat, a well-known Chalcidologist from India.
