First metasomal tergum brown and nitid; widest pre-apically; apically narrower and curvaceous; medially with a shallow curve similar to inverted “U” shape; without any noticeable sculpture except for some fine striations preapically. Second metasomal tergum brown and nitid; subrectangular; ovipositor short and thick at base, barely exserted from hypopygium. Ovipositor sheaths broad in lateral view; hypopygium short in length, ovipositor sheath with setation only at distal 1 / 3; setae long and scattered.

Male. Similar to female.

Distribution. India: Maharashtra

Material examined. Holotype, female on card, INDIA, Maharashtra, Mumbai, Borivli, 11.x. 2011, emerged from parasitized larvae of Elymnias hypermnestra   caterpillar on coconut, leg. Blaise Pereira. Paratypes two females and six males on card and two females and males, dissected, on slide, with same data as holotype. All types deposited in National Bureau of Agriculturally Important Insects ( NBAII), Bangalore, India. Code 111011.

Comments. The most distinctive characters include yellow silken cocoons. Antenna with scape yellow (except apical edge brownish black); scuto-scutellar groove distinctly crenulate with nine deep costulae; mid legs light yellow (except coxae and tarsal claws brownish). Propodeum smooth and nitid with shallow lateral longitudinal carinae inclined medially, areola absent; spiracles conspicuously large and round. First metasomal tergum brown and nitid; widest pre-apically; apically narrower and curvaceous at the edges; medially with a shallow dent or curve similar to inverted “U” shape; without any noticeable sculpture except for some fine striations pre-apically. Ovipositor broad in lateral view and ovipositor sheaths covered with long setae in distal 1 / 3.

Discussion. Resembles G. spodopterae Ahmad et al.   in having a row of long hairs on basal half of hind wing. Differs in having mid femur entirely yellow (mid femur entirely black in G. spodopterae   ). Also differs in having metasomal tergum II more or less sub rectangular and about 2.5 times as broad apically as long medially (tergum II triangular and about 2 times as broad apically as long medially in G. spodopterae   ). Cocoons are gregarious and yellow in colour (cocoons are white in colour in G. spodopterae   ).

G. hypermnestrae   is also compared with the description of G. “ melanitisi   ” and it differs in rugosity of first tergum which is almost smooth except for some very fine striations pre apically. (tergum I rugose in G. “ melanitisi   ”). Also the apex first tergite is much wider. (tergum I much narrower apically in G. “ melanitisi   ”) Second tergite smooth and subrectangular (much more rugulose and triangular in G. “ melanitisi   ”).

In comparisons with Indian species G. bhupali   it strongly differs in having smooth propodeum with lateral longitudinal carinae inclined medially, spiracles large and round, tergite I smooth and ovipositor sheath with many long setae scattered in distal half. (propodeum much more rugose and sculptured with median carina, spiracles small and oval, tergite I rugose-reticulate and ovipositor sheath with few distal setae in G. bhupali   ).

Host Record. Elymnias hypermnestra   larva ( Lepidoptera   : Nymphalidae   ) on coconut palm ( Cocos nucifera   ).

Etymology. Gender, neutral. This species is named after the host E. hypermnestra   .
