Discussion — N. macropunctatus is allied to N. micropunctatus but there is difficulty in distinguishing them from each other. In addition to most of the colour and structural features as discussed under the latter, many ratioes and the genitalia make them further distinct from each other. As far as its ecological adaptations are concerned, these are almost similar to N. micropunctatus. Both the species are coexistent and sometimes may be caught in the same sweep. Since the resting plants are the same, so there may be similar possibility with regard to their host plant as well. In its population density it is somewhat ahead to N. micropunctatus. Etymology — Species is named after the macropunctation of the frontal area. Neostromboceros maculatus sp. n. (Figs 3, 7, 11, 15, 19, 23,27) Female — Colour: Body black, whitish are: dorsal margin of pronotum, parapterum, metatrochanter and adjoining parts of coxa and femur, basal 1/2 outer aspect of protibia, basal 2/3 of outer aspect of mesotibia, complete basal 2/3 of metatibia. Wings hyaline, venation including costa, subcosta and stigma fuscous. Structure: Average length 7 mm. Antenna tapering towards apex, 2 x head width, flagellum not compressed, segments 3 and 4 as: 6:5. Clypeus (Fig. 3) shallowly emarginate, labrum (Fig. 3) broader than long as 3:2 with rounded anterior margin, malar space 0.5 x diameter of median ocellus, supraantennal pits double, not connected, deep, anterior one smaller. LID:IDMO:EL =1:1.3:1.1, POL:OCL:OOL =1:1.2:1.2. Frontal area at level of eyes, median fovea in form of distinct pit just above supraclypeal area and in form of a shallow pit anterior to median ocellus, postocellar furrow absent, interocellar furrow fine, circumocellar furrow distinct; lateral furrows distinct, excurved, ending just before hypothetical hind margin of head: postocellar area convex, broader than long as 3:2, head narrowing behind eyes. Hind wing with vein lr - m joining Rs away from junction with R+Sc. ICD: ITD = 1:4, mesoscutellum subconvex, appendage ecarinate. Tarsal claw (Fig. 7) with subapical tooth shorter than apical one, basal lobe distinct, metabasitarsus longer than following 3 joints combined as 6:5, IATS:MB:OATS = 1:2.7:0.9. Ovipositor sheath as in Fig. 11 (lateral view), and Fig. 15 (dorsal view). Lancet (Fig. 27) having 6 serrulae. Sculpture: Head and thorax impunctate except posterior margin of mesoscutellum that bears a row of deep distinct punctures. Abdomen impunctate, subshining. Pubescence: Silvery, 0.5 x scape length. Male — Average length 6 mm. Similar to female except colour (brownish to fuscous) of basitarsi and following 1-2 joints. Genitalia: Penis valve (Fig. 19), gonoforceps (Fig. 23).
