Mesosoma (Figs 14 & 14A). Mesosoma median length = 1.28 mm; mesosoma length/width (1.05) = 1.21. Mesoscutum with coarse punctate sculpture that fades near the scutellar groove with shallow pilosity; scutoscutellar groove distinctly crenulate with 12 deep costulae; scutellum with shallow and distantly placed punctations, scutellum with shallow pilosity, laterally with costulate sculpture which become narrower and elongated towards posterior edge; posterior band of scutellum polished; metanotum subrectangular. Mesopleuron dull rugose with dense pilosity in diagonal anterior half (posterior half smooth shiny and devoid of setae). Metapleuron smooth and shiny, anterior pit deep. Hind coxae shiny, laterally with shallow punctures.

Propodeum with clearly defined wide, strong and shiny areola (areola devoid of setae); propodeum rugose with shallow pilosity (setae confined near the lateral edges) in basal half excluding areola. Areola 1.05× longer than wide; anterior diagonal carinae of propodeum shallowly merging anterior margin of propodeum (evident in KOH treated samples Fig. 14A); areola open near the anterior edge; costulae complete and prominent, anterior diagonal carinae sloping down behind spiracles; spiracles large and oval.

Type material. Holotype, one female on card, INDIA, Karnataka, Jalahalli, 14.viii.13, coll. Ashok Sengupta, ex. larvae of Curetis thetis (Drury) ( Lepidoptera : Lycaenidae ) (Fig. 18) on (= Pongamia ) pinnata (L.) Panigrahi ( Fabaceae ). Paratypes, two females and two males on card, with same data as holotype.

Repository. All types & specimens deposited in NBAII, Bangalore, India. Code. NBAII /Bra/Mic/Para/ arka / 14813-A(Holotype), NBAII /Bra/Mic/Para/ arka /14813-B (Paratype).

Etymology. The specific epithet ‘ arka ’ is of Sanskrit origin and is coined after the host ‘ Curetis thetis ’ commonly known as ‘ Indian Sunbeam’. ‘ Arka ’ in sanskrit means ‘sunbeam’.
