Centistidea acrocercopsi Ahmad & Pandey sp. nov. Figs 1-4

Material examined.

Holotype: INDIA • ♀: Uttar Pradesh, Etah, 7.VIII.2004; ex. Acrocercops phaeospora (Meyrick) on Syzygyium cuminii , Z. Ahmad leg. (ZDAMU). Paratype: 1♀, with same data as holotype (HB-138, ZDAMU).

Diagnosis.

Following the key to East Palearctic and Oriental species of the genus Centistidea Rohwer ( Ranjith et al. 2018), C. acrocercopsi sp. nov. keys near to C. rugator ( Ranjith et al. 2018); however, it differs in the following characters ( C. rugator in parentheses): (i) body largely yellowish (body largely yellowish except tergites 1-6 dark brown dorsally), (ii) length of eye 1.3 × long as temple in dorsal view (length of eye 2.90 × as long as temple), (iii) ovipositor sheath 0.10 × as long as fore wing length (0.20 × as long as forewing), (iv) first tergite smooth, widening medially, slightly narrowing basally and apically, 4.0 × as long as its maximum width (first tergite smooth, widening medially, distinctly narrowing basally and apically, 3.0 × as long as its maximum width).

Description.

Female: body length: 1.7 mm; length of fore wing: 2.1 mm; length of antenna: 1.7 mm.

Head: ca. 2 × as wide as long in dorsal view; length of eye 1.3 × as long as temple in dorsal view; temple and vertex shiny with indistinct punctures; OOL: POL: AOL: OD = 6: 3: 2: 1.5; inner margin of eyes subparallel; face distinctly convex medially, flattened laterally and almost smooth and shiny; clypeus smooth and evenly convex; malar space ca. 2 × as long as basal width of mandible; antenna 14-segmented, F1 as long as F2, apical flagellomere pointed.

Mesosoma: 1.4 × as long as wide; mesoscutum shiny with indistinct punctures, notauli only anteriorly impressed and finely crenulate; prescutellar furrow poorly developed without any groove; scutellum smooth and shiny, medio-posterior depression of scutellum elliptical; propodeum somewhat smooth, with a complete median longitudinal carinae and two transverse carinae posteriorly, few rugosities adjacent to median longitudinal carina; meso- and metapleuron almost smooth and shiny.

Wings: Pterostigma with long and slender apical expansion, 2.7 × longer than wide, vein r issuing from its middle; vein 1-M 1.5 × longer than vein m-cu; vein 1-CU1 0.9 × as long as vein 2-CU1.

Legs: Hind coxa smooth, length of femur, tibia, and basitarsus of hind leg 3.0 ×, 7.1 ×, and 4.0 × their maximum width, respectively; length of hind tibial spur 0.30 × as long as hind basitarsus. Hind tarsal claw large and without acute lobe.

Metasoma: 1.5 × as long as wide; first tergite, smooth, widening medially, slightly narrowing basally and apically, 4.0 × as long as its maximum width; second tergite sclerotized with strong longitudinal striations; hypopygium small, membranous, desclerotized, sparsely setose at apex, not surpassing end of metasoma; ovipositor thick, setose, distinctly shorter than petiole and hind basitarsus.

Color: Largely yellow except for the following: antenna (except for scapus and pedicel yellow), veins, pterostigma, and ovipositor apically brown; wings moderately infuscate apically.

Male.
