    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

    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

    Micraspis pusillus sp. n. (Coleoptera: Coccinellidae) is described and illustrated from the northeastern region of India. It is unusual in possessing very large eye canthus and is the smallest species of the genus known from India so far

    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)

    Background and aims. The Doryctinae is a considerably diverse, poorly studied group of parasitoid wasps and one of the most diverse subfamilies within Braconidae. Taxonomic knowledge of this group remains highly incomplete, specially in the tropics. In Mexico, it has been reported as the subfamily with the highest number of recorded genera. A preliminary Barcoding study carried out in the Chamela region, located near the Mexican pacific coast in Jalisco, identified 185 barcoding species of Dorytinae assigned to 19 identified doryctine genera. This work updates the later study, representing a three years effort to assess the species richness of this subfamily for the Chamela region. Materials and methods. Ten collecting field trips of 5 to 10 days each were carried out from June 2009 to May 2011. A 2% divergence criterion using the BIN system implemented in BOLD was followed in order to establish species boundaries among the specimens that were collected. Results and conclusions. A total of 961 specimens were collected, from which 883 COI sequences were obtained. The sequences generated corresponded to 289 barcoding species and 30 identified genera. The most speciose genera were Heterospilus Haliday (170 spp.), Ecphylus Förster (19 spp.), Allorhogas Gahan (15 spp.) and Callihormius Ashmead (14 spp.). Addition of previously collected material increased the diversity of the subfamily in the region to 34 genera and 290 species. Paraphyly of Heterospilus with respect to Neoheterospilus and Heterospathius was again recovered. Twenty new species and two new genera (Sabinita Belokobylskij, Zaldívar-Riverón et Martínez, Ficobolus Martínez, Belokobylskij et Zaldívar-Riverón) have been described so far from the material collected in this work
