( Figs 1–2 View FIGURE 1 View FIGURE2 )
Material examined. “ INDIA: Karnataka, Kadnur , 14.xi.2005, Malaise Trap, ex. Ranjith, A.P. ” Description. Holotype, female, body length 13.7 mm, fore wing 10.5 mm, antennae 13.7 mm, ovipositor 0.7 mm.
Head. Antennae with 64 segments. Terminal flagellomere acuminate. Medial flagellomeres 3.00× as long as wide. Third segment of maxillary palp swollen, 3.60× as long as wide ( Fig. 1D View FIGURE 1 ). Second segment of labial palp swollen, 2.20× as long as wide. Face transversely striate anteriorly and postero-laterally rest rugose with a short medial longitudinal ridge anteriorly ( Fig. 1B View FIGURE 1 ), protruding in lateral view, with long setae ( Fig. 1A View FIGURE 1 ). Distance between posterior ocelli: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye= 6.5: 15.5: 6. Occipital carina complete, more or less evenly rounded ( Fig. 1C View FIGURE 1 ). Frons with medially depressed area, transversely striate laterally with a pair of anteriorly diverging carinae ( Fig. 1C View FIGURE 1 ). Vertex smooth without midlongitudinal groove ( Fig. 1C View FIGURE 1 ).
Mesosoma. Mesoscutum smooth, shiny, sparsely punctate with long setae and a faintly crenulated midlongitudinal groove midposteriorly ( Fig. 1E View FIGURE 1 ). Notauli impressed, crenulate joining with midlongitudinal groove basally ( Fig. 1E View FIGURE 1 ). Scutellar sulcus arched with a single carina medially and incomplete crenulations posteriorly ( Fig. 1E View FIGURE 1 ). Scutellum smooth and shiny with long setae. Mesopleuron smooth and shiny with long setae ( Fig. 1F View FIGURE 1 ). Precoxal sulcus long, weakly impressed ( Fig. 1F View FIGURE 1 ). Medial area of metanotum with complete midlongitudinal carina. Propodeum extensively rugose, transversely striate Midposteriorly, lateral carina distinct posteriorly and protruding ( Fig. 2A View FIGURE2 ).
Wings. Fore wing vein 1CUb 9.20× as long as 1CUa. Vein 3SRa 2.30× as long as r. Vein 3SRb as long as 3SRa. Vein r and 3SRb sinuate ( Fig. 2E View FIGURE2 ). Hind wing vein M+CU 1.60× as long as 1M. Vein R quadrate ( Fig. 2F View FIGURE2 ). Vein m-cu absent ( Fig. 2F View FIGURE2 ).
Legs. Hind coxa smooth with dorsal tubercle ( Figs 1A View FIGURE 1 , 2E View FIGURE2 ). Claws with pointed basal lobe ( Fig. 4F View FIGURE 4 ).
Metasoma. First metasomal tergite longitudinally striate laterally, medially rugose with smooth median field mid posteriorly, 3.70× as long apically wide, posteriorly with well developed shoulders, complete midlongitudinal carina and lateral protuberances medially. Second metasomal tergite longitudinally striate with complete midlongitudinal carina and pair of distinct lateral triangular lobes, 1.30× as long as third tergite, 2.10× as long as apically wide, without smooth triangular area antero-medially ( Fig. 2B View FIGURE2 ). Third metasomal tergite longitudinally striate, 1.10× as long as apically wide with midlongitudinal carina not extending up to posterior margin ( Fig. 2B View FIGURE2 ). Fourth metasomal tergite longitudinally striate without midlongitudinal carina at anterior half ( Fig. 2C View FIGURE2 ). Fifth metasomal tergite transversely striate ( Fig. 2C View FIGURE2 ). Sixth metasomal tergite smooth and shiny ( Fig. 2C View FIGURE2 ). Hypopygium curved ventrally ( Fig. 2D View FIGURE2 ). Ovipositor sheath setose. Ovipositor with distinct ventral serrations ( Fig. 2D View FIGURE2 ).
Colour. Body yellow except eyes, ocelli, frons, occiput medially, mesoscutum laterally near notaular area, mesopleuron, propodeum, mid and hind coxae, fifth and sixth metasomal tergites, hypopygium, ovipositor sheath reddish brown, venation brown except 1R1 and parastigma, pterostigma apically yellow.
Male. Unknown.
Distribution. India (Karnataka).
Host. Unknown.
Etymology. APR dedicates this species to the ‘master blaster’, Sachin Ramesh Tendulkar, former Indian cricketer, for making cricket a passion among Indian youngsters.
Comments. Cystomastacoides sachini sp. nov. differs from all described species by its unique body colour combination and slender first metasomal tergite. Cystomastacoides sachini sp. nov. comes close to C. coxalis in having occipital carina more or less evenly rounded and apex of fore wing infuscated. But it differs from the latter by the following characters; antennae yellow (vs brown), pterostigma yellow apically (vs yellowish brown apically), third segment of maxillary palp 3.60× as long as wide (vs 3.10× as long as wide), frons transversely striate laterally (vs rugose laterally), mesoscutum with crenulate midlongitudinal groove posteriorly (vs without midlongitudinal groove), third metasomal tergite with midlongitudinal carina (vs without midlongitudinal carina).
