Abstract

The pentatomine tribe Strachiini Stal of the stinkbug family Pentatomidae Leach comprising the genera Bagrada Stal, Eurydema Laporte, Madates Strand, Stenozygum Fieber and Strachia Hahn from Indo-Pakistan subcontinent including 28 species with four new species and three new records is described in detail with special reference to their metathoracic scent auricles and male and female genitalia In addition to these species, genera and species were also described or studied with new species outside Indo-Pakistan subcontinent for these were either earlier placed or appeared close to the above studied genera of Strachiini. For instance the genus Grossiana Ahmad Khan (1979) representing Strachia persignata (Walker) from Queensland, Australia and Murgantia Stal representing M. histrionica from new world were studied and in agreement with Ahmad and Khan (1979) and Brailovsky (1989) these appeared closely related to the above general Strachiini. The genus Capnoda Jakovlev representing C. batesoni Jakovlev from Eukrane described and illustrated by Puchkov (1961 and 1965) was also included but unfortunately not a single specimen of this or any other species of this genus could be procured, therefore it could not be confirmed whether it actually belonged to the tribe Strachiini in the present sense. In addition to these the genus Gynenica Dallas originally included in the key of his division Eurydemaria by Distant (1902) (equivalent to Strachiini stal for which Leston (1953a) suggested a new tribe within Pentatominae although he did not formally name or describe it and for which Ahamd and Mohammad (1980) described a new tribe Lestocoriini with Lestonocoris Ahmad and Mohammad and Umgababa Leaton was also studied with species of the above genera included by Ahmad and Mohammad (1980). The present studies confirm the findings of not only the above authors but also of Schaefer and Ahmad (1987) who carried out a cladsitic analysis of the members of this tribe Distant (1902) also included in his division Agonoscelis Stal which was originally placed by Dallas (1852) in his Halyidae and Atkinson (1888) following Stal (1876) placed it in Stal’s tribe Agonoscelaria and Ahmad (1979) in his revision of Pentatomidae from Pakistan with their relationships treated it within the tribe Agonoscelini was also studied with A. mubila (F.) from Dacca. Bangladesh and a new species A. karachiensis from Karachi, Pakistan and the treatment in an independent tribe by Atkinson (op.cit) and Ahamad (op. cit) were presently confirmed. Similarly Knightiella Ahmad and Khan (1979) representing Stenozygum flavifons Distant from New Calodenia was also studied for which the above authors (op. cit) tentatively proposed Knightiellini and which taxon was formally described as such by Ahmad (1979). The present studied also confirm their findings. Aplerotus Dallas representing A. grossi from Australia previously treated with other painted bug genera by Kirkland (1909) and later under his Mecidea group by Gross (1976) and considered by Ahmad et al. (1980) close to Niarius Stal in Diemenini was also included for resolving its phylogenetic status. The brilliantly patterned genera Cat acanthus Stal formerly treated in his Nezaria ( a synonym of Pentatomini Leach) representing from Australian and Oriental regions and Parastrachia Distant recently treated under the subfamily Parastrachiinae of the family Cydnidae by Schaefer et. al. (1988) and also Runibia Stal (1961) another painted bug genus representing R. decorate (Dallas) from Texas, North America were also studied to resolve their phylogenetic status. Dallas (1851) and Walker (1867) described a number of species as Strachia which later were included under the genus Runibia Stal by Kirkland (1908 and 1909) Detailed morphology of Eurydema pluchra (Westwood) from Pakistan is also carried out to understand the characters of taxonomic importance. A cladistic analysis of all the described genera of Strachiini from Indo-Pakistan subcontinent with Grossiana. Murgantia, Capnoda, Knight Ella, Aplerotus and Runibia and all the known species of the starchiness from Indo-Pakistan subcontinent is also carried out to understand the relationships of the included taxa
