Head: Above smooth, without punctures but with faintly depressed short irregular lines in anterior third (e.g., Fig. 3 View FIGURES 3 – 4 ), covered with sparse setae, with tylus rounded and as long as jugae, eyes extremely large, occupying almost entire lateral surface of head; length head 0.75 (0.87); width across eyes 1.19 (1.35); interocular space 0.69 (0.75); interocellar space 0.50 (0.57); eye-ocellar space 0.04 (0.04); eye length 0.57 (0.69); eye width 0.23 (0.30). Labium slightly exceeding fore coxae ( Fig. 5 View FIGURES 5 – 6 ), 2nd segment reaching base of head ( Fig. 4 View FIGURES 3 – 4 ); length of segments: I 0.39 (0.46); II 0.39 (0.39); III 0.18 (0.27); IV 0.32 (0.36). Length of labrum 0.34 (0.34). Antennae with 1st segment very short, slightly exceeding apex of tylus; length of segments: I 0.18 (0.20); II 0.57 (0.64); III 0.46 (0.46); IV 0.64 (0.60).

Thorax: Pronotum ( Figs. 3, 4 View FIGURES 3 – 4 ), posterior margin evenly and shallowly concave, entire pronotum covered with sparse setae, anterior lobe smooth, shiny, posterior lobe with sparse large punctures; below with a narrow median groove for receipt of labium ( Figs. 5 View FIGURES 5 – 6 ); median length 1.21 (1.38) (anterior lobe 0.69 (0.73)); width at posterior margin 0.87 (0.98); width at anterior margin 0.75 (0.87). Thoracic scent gland evaporative area as in Fig. 8 View FIGURES 7 – 8 . Femora covered with long setae. Scutellum length 0.39 (0.43); width 0.39 (0.46). Hemelytra generally narrowed with lateral margins concave and highly constricted at level of claval commissure ( Fig. 9 View FIGURES 9 – 10 ) and at about base of abdomen and second abdominal segment ( Fig. 1 View FIGURES 1 − 2 ); corium elongately tapering to reach abdominal tergum 3, apical corial margin almost straight, with costal margin gradually slightly dilated, widest at about mid length; length of hemelytra 2.89 (2.80); length of corium 1.47 (1.65); claval commissure 0.29 (0.32); membrane shiny, with reduced venation with only 2 veins distinct ( Fig. 9 View FIGURES 9 – 10 ); width membrane 0.85 (1.10).

Abdomen: Gradually widened from anterior margin of segment III to V, then gradually narrowed posteriorly ( Figs. 11 View FIGURES 11 − 12 , 17 View FIGURES 17 − 18 ). Tergum almost uniformly sclerotized (e.g., Fig. 11 View FIGURES 11 − 12 ); tergum VII in male with punctures in posteriormedial area ( Fig. 17 View FIGURES 17 − 18 ); connexiva with outer areas with sparse setae, in addition with 1 or 2 long setae with distinct bases particularly in posterior area of each segment; a few sparse short setae present in irregular rows along sutures of IV–V and V–VI ( Figs. 11 View FIGURES 11 − 12 , 17 View FIGURES 17 − 18 ); abdominal sternum V broad and complete, sternum VI in female only slightly narrowed mesally by ovipositor but complete anteriorly ( Fig. 12 View FIGURES 11 − 12 ), uniformly sclerotized, covered with 2 or 3 types of short to medium length setae in addition to a few blunt setae, as well as trichobothria, setae longer towards posterior end, particularly on segments VI and VII ( Fig. 12 View FIGURES 11 − 12 ).

Female genitalia: As in generic description ( Figs. 14–16 View FIGURES 13 – 14 View FIGURES 15 – 16 ). Ovipositor with first ramus traversing to almost 4/5 length of first gonapophysis ( Fig. 15 View FIGURES 15 – 16 ); second gonapophysis spatulate with sparse minute setae in two rows, second gonocoxae almost crescentic ( Fig. 16 View FIGURES 15 – 16 ).

Male genitalia: As in generic description ( Figs. 20–23 View FIGURES 19 – 20 View FIGURES 21 – 22 View FIGURES 23 ).

Egg. Cream coloured. Elongate, narrow and parallel sided, ends gradually rounded, more narrowly on posterior end than micropylar end, which has 6 small knob-like micropyles arranged in an open circle. Length 1.21, maximum width 0.34.

Distribution. India, Western Ghats, Karnataka, Kodagu (Coorg) district, Makuta range, 12°04’39 N; 75°43‘ 33.6 E and altitudes of up to 909 metres.

Etymology. The new species name proposed here, I. makutaensis , alludes to the Makuta range locality within Western Ghats in south India where the specimens were collected.

Notes. All the specimens examined were collected from the canopy of Vateria indica trees.

Vateria indica , the white dammar, belongs to the plant family Dipterocarpaceae . This plant is indigenous to the Western Ghats , Karnataka , Kerala and Tamil Nadu regions of India. It is threatened by habitat loss. This tree grows like a palm but has blunt thorns along its trunk. This is a slow-growing species, found primarily in the west coast evergreen forests, and also occasionally in secondary evergreen dipterocarp forest in the south (Wikipedia, accessed 23 August 2016).
