Figs 10-13 Material examined. Holotype , female, "INDIA: Uttar Pradesh, Aligarh, 10.VIII.2005; ex Trachys sp. on Corchorus sp., Coll. Zubair Ahmad (ZDAMU)". Paratypes , 3 females and 2 males; with same data as holotype. Diagnosis. Following the key to world species of Parachremylus by Belokobylskij and Maeto (2006) , Parachremylus trachysi sp. nov., runs near to another Indian species viz., P. oblongus (Papp). The new species shares similarities with P. oblongus in having the presence of longer temple; transverse diameter of eye 4.0 x as long as temple length in dorsal view; malar space 1.2 x basal width of mandible; mesopleuron smooth in upper half, striation partly present in subalar depression only; 1-4 segments of hind tarsomere with narrow and partly indistinct flanges and shallow field of hind half of mesonotum with a medio-longitudinal carinae running up to middle of mesoscutum. However, the new species can easily be distinguished from P. oblongus by having the head and mesosoma densely setose (head and mesosoma sparsely setose in P. oblongus ); median longitudinal carina of metasoma reaching up to almost T3 (median longitudinal carina of metasoma reaching up to almost T2 in P. oblongus ); pterostigma 3.5 x as long as high (pterostigma 5.0 x as long as high in P. oblongus ); malar space 1.2 x as long as basal width of mandible (malar space 0.75 x as long as basal width of mandible in P. oblongus ); scutellar sulcus with three crenulae (scutellar sulcus with five crenulae in P. oblongus ); forewing veins 2RS and 3RSa 3.5 x as long r (forewing veins 2RS and 3RSa 2.7 x as long r in P. oblongus ) Description. Female, body length: 2.1 mm; forewing: 2.0 mm. Head. Antennae 27 segmented, about as long as body length, F1- F2 3-3.3 x as long as apical width, except the apical segment which is 4.5 x as long as wide; head transverse, 1.5-1.7 x as wide as long in dorsal view and 1.2 x as high as long in lateral view; eyes in lateral view 1.2 x as high as wide, 4.0 x as long as temple, inner margin of eyes not parallel; temple granulate, sparsely setose, its widest part behind eye 0.25 x as long as width of eye; occipital carina dorsally slightly curved towards ocelli, rather widely interrupted medially; occiput with uniform transverse striations; AOL: POL: OOL: OOD = 2:1:3:2; face polished, laterally shagreened, sparsely setose, 1.5 x as wide as long medially; clypeus 1.6 x as wide as long; vertex granulate, sparsely setose; malar space 0.4 x as long as eye and 1.2 x as long as basal width of mandible; Mesosoma. Mesosoma 1.5 x as long as wide in dorsal view, 1.6 x as long as high in lateral view; pronotum small, indistinct; median and lateral lobes of mesoscutum granulate, sparsely setose; notauli broad anteriorly, shallow posteriorly, shallow field of hind half of mesonotum with a medio-longitudinal carinae running up to middle of mesoscutum; scutellar sulcus deep and 3.5 x as wide as long with three crenulae; scutellum indistinctly granulate, rather densely setose; propodeal areola with a median longitudinal carina anteriorly, two transverse carina inside, lateral areola with longitudinal striations anteriorly and inside with transverse ruguae; propleuron smooth; mesopleuron smooth and polished except few striation at subalar depression. Wings. Forewing 2.5 x as long as wide, as long as body; pterostigma 3.0 x as long as wide, issuing r from its middle; length of marginal cell along R1a about 1.2 x as long as pterostigma; 2RS and 3RSa 3.5 x as long r respectively; hind wing vein M+CU 0.8 x 1M; hind femur 3.4-3.6 x as long as broad medially; hind tibia 1.2 x as long as hind tarsus; hind basitarsus 0.6 x as long as tarsomere 2-4 combined. Metasoma. Metasoma dorsally sub-sclerotized, 1.0 x as long as head and mesosoma combined, T1 evenly and distinctly broadening posteriorly, T2 2.1 x as broad as long, 1. 5 x as long as T3; T3 3.0 x as broad as long; T4 4.0 x , as wide as long medially; basal pair of carinae of T1 meeting at its basal one-third and continuing a medio-longitudinal carinae up to apical end of T3; all tergites sub- sclerotized; ovipositor sheaths setose and blunt, in lateral view 1.2 x as long as hind basitarsus. Color. Vertex yellow with brown marking, mandibles, scutellar sulcus, metanotum creamish; tip of mandible, mesoscutum, claws, dark brown; antennae brown; ocelli transparent; eyes, stemmaticum black; wings hyaline, pterostigma pale yellow, veins brown; scutellum, propodeum, legs yellow. Male. Same as ♀ except body size (2 mm). Host. Trachys sp. on Corchorus sp. (Wild Jute). Distribution. India (Uttar Pradesh). Etymology. The species name is derived from the name of the genus of the host insect. Figures 10-13.
