In the light of the recent revival of interest in butterflies in India in general and islands in particular,we present a checklist of the butterflies of these islands. For the first time in many years we take a critical look at the butterflies recorded as occurring on the Andaman and Nicobar islands. We distinguish between species that are known to occur definitely on these islands versus those which are stragglers and those which have been reported on the basis of erroneous identification. We also indicate which species/subspecies are endemics and present an overview of the knowledge of the life histories,larval food plants and natural history that is known of these butterflies. A bibliography of the butterflies of the Andaman and Nicobar islands is included.

It is a very distinctive species, males of which can be identified easily even in the field because the inner outline of the protibiae is distinctly curved, a feature which is unknown or considerably less prominent in any other Agabus Leach, 1817. The new species undoubtedly belongs to the subgenus Acatodes Thomson, 1859, although males lack the preapical spine of the median lobe, a character which is alsoseen in the Nearctic Agabus audeni Wallis, 1933, and the Holarctic Agabus inexspectatus Nilsson, 1990. Due to an unusual combination of external characters (e.g., double reticulation, shape of tibiae and of pro- and metasternal processes) it is not easyto assign the species to one of the known species groups of the subgenus. It seems likely, however, that it belongs to the confinis-group because several other characters are shared with most members of this group. A few features suggest a closer relationship to Agabus thomsoni (J. Sahlberg, 1871) and Agabus zetterstedti Thomson, 1856. The new species raises the number of members of the confinis-group to 36, seven of which occur in China. A list of all Afrotropical and Palearctic members of this groupis given and their median lobes are figured in lateral view. The lectotype of Agabus turcmenus Guignot, 1957 is designated, and its habitus and aedeagus are illustrated for the first time. Some notes on the distribution and external morphology of A. inexspectatus are included.

The types are deposited in the Entomological Museum of the Universidad del Valle (MUSENUV). A set of infrageneric groups within Loneurais proposed based on the structure of the male hypandrium and phallosome. The species of the genus are assigned to the groups recognized in this classification.

查看更多>>摘要：Two new species of Leptohyphidae are described based on nymphs and adults: Traverhyphes {Traverhyphes) frevo sp. nov. and Tricorythopsis spongicola sp. nov. Traverhyphes (T.) frevo can be distinguished from other species, among other characteristics,by the presence of curved penile spines inserted laterally, and posterolateral projections of styliger plate very short and pointed distally in lateral view. Tricorythopsis spongicola can be distinguished from the others species, mainly by the presence of spine-like lateral projections present on apical part of penes in the male imago, and by the tarsal claws with four to five marginal denticles, and two rows of 2 + 3 submarginal denticles with apical setae in the nymphs.
