New Indian banyan plant bug.
15 pages : illustrations (some color) ; 26 cm.A new genus and new species of the plant bug, Chimairacoris lakshmiae Yasunaga, Schuh, and Cassis are described from Bangalore, India. This morphologically and ecologically specialized mirid belongs to the subfamily Phylinae on the basis of genitalic structures and is currently considered best placed in the subtribe Oncotylina of the tribe Phylini. Its morphological convergence with termatophyline mirids and placement within the Phylinae are discussed. It is associated with psyllid leaf galls on Indian banyan, Ficus benghalensis. The gall-producing psyllid, Trioza sp., and a mealybug, Phenacoccus parvus, are confirmed as prey of this unique mirid. A similar phenomenon observed in some Montandoniola spp. (Anthocoridae) and Fingulus species (Miridae: Deraeocorinae), which are associated with thrips species of the genus Gynaikothrips (Thysanoptera: Tubulifera) on Ficus microcarpa, is also documented
Calvia explanata sp. n. (Coleoptera: Coccinellidae: Coccinellinae) from the Indian Subcontinent
Calvia explanata sp. n. (Coleoptera: Coccinellidae), externally similar to and commonly misidentified as C. albida Bielawski, is described from India and Nepal
Two new species of Scymnini (Coleoptera: Coccinellidae) from Karnataka, India
The Scymnini (Coleoptera: Coccinellidae) of the Indian region is rich and highly speciose, with nearly 90 described species and scores of undescribed species (Poorani 2002). There is a dire need to systematically revise the genera and species of this tribe from the Indian region. Due to paucity of representative collections covering the entire region and lack of access to types, it is difficult to identify most of the Scymnini of the Indian region to species. As a result, many economically important species remain poorly characterized, or worse, unnamed.
Two economically important and unique species of Scymnini (Coccinellidae) belonging to Horniolus Weise (1900) and Scymnus (Pullus) Mulsant (1846) from the Southern Indian state of Karnataka that have remained unnamed for long are treated in this paper. These species are externally similar to other known species and often misidentified. Horniolus sororius sp. n. and Scymnus (Pullus) rajeshwariae sp. n. (Coleoptera: Coccinellidae) are described here and illustrated with notes on their biology and related species

Redescription of Platynaspis flavoguttata (Gorham) (Coleoptera, Coccinellidae) and notes on nomenclature of Platynaspis kapuri Chakraborty & Biswas
Platynaspis flavoguttata (Gorham) (Coleoptera: Coccinellidae) is redescribed and the male genitalia are illustrated for the first time. It is also recorded from Sri Lanka for the first time. Platynaspis bimaculata (Hoang, 1983) is a new junior synonym of Platynaspis bimaculata Pang & Mao, 1979 (new synonym). Platynaspis kapuri Chakraborty & Biswas, 2000, the replacement name for Platynaspis bimaculata Pang & Mao, 1979 established by Ukrainsky (2007), is also the new replacement name for Platynaspis bimaculata (Hoang, 1983), as both are junior homonyms of Platynaspis bimaculata Weise, 1888 besides being synonyms. Platynaspis hoangi Ukrainsky (2007) is an unnecessary replacement name for P. bimaculata (Hoang)
Caenohomalopoda longiscapus Gupta & Poorani, 2008, sp. nov.
<i>Caenohomalopoda longiscapus</i> sp. nov. (Figs 1–10) <p> <b>Diagnosis.</b> In Zhang & Huang (2006), <i>C. longiscapus</i> sp. nov. would key out to the same couplet with <i>C. shikokuensis</i> (Tachikawa). The female of the new species appears to be similar to the females of <i>C. shikokuensis</i> and <i>C. longistylata,</i> but clearly differs from these species by the different dimensions of the antennal segments and infuscation pattern on the forewing. The antenna in females of the new species has the basal segment of clava distinctly longer than other two segments individually, and apical portion of clava paler than the rest of the antenna. All funicle segments are longer than wide. Scape elongate, 5.2x as long as wide; pedicel 2.1x as long as wide. Forewing with the vertical infuscate band towards postmarginal and stigmal veins much broader. The horizontal band separating two hyaline areas in the apical half of forewing much narrower than in <i>C. shikokuensis</i>. The hyaline spot in the apical portion of the forewing almost bean shaped.</p> <p> In <i>C. shikokuensis</i> the antenna is dark brown, except F4 and apical half or so of clava yellowish. Fl slightly longer than wide, rarely quadrate, F2, F3 quadrate or slightly longer than wide. Forewing about 2.8x as long as wide; the vertical infuscate band, towards postmarginal and stigmal veins perpendicular to anterior margin of forewing, narrow, and the horizontal band separating two hyaline areas in the apical half of forewing much broader. Scape about 2.5x as long as wide.</p> <p> <b>Plate-I.</b> Adult female of <i>Caenohomalopoda longiscapus</i> sp. nov.</p> <p> In <i>C. longistylata</i> apex of F3 is pale yellowish, F4 is completely dull yellow; scape is 1.96x as long as wide; ovipositor about 0.5x gaster length and pedicel is 1.24x as long as wide.</p> <p> <b>Description.</b> Female (Plate-I): Body length (holotype) 1.88 mm.
