| A revision is given of the Oriental genus Matapa Moore. Two species, M. intermedia and M. deprivata, and one subspecies, M. intermedia nigrita, are described as new. A key to the nine species known at present is provided. Figures are given of male and female genitalia, and of forewings of males. The phylogeny of the genus and its geographic history are discussed. It is shown that three monophyletic groups can be distinguished, which all originated in mainland Southeast Asia. The occurrence of one species in India is the result of a geologically speaking recent invasion. There are indications of a double colonization of Celebes from the Philippines. |

| 1. Pyrgus alveus caucasius Picard and Pyrgus jupei Alberti In a paper on Pyrgus bellieri, Picard (1949: 57) casually named the populations of Pyrgus alveus from the Caucasus and Transcaucasia caucasius. According to Picard, Reverdin (1915) confused this form with the Chinese sifanicus which has different genitalia. The description of caucasius is very short: "Il faut mentionner l'extrême petitesse de la pièce constituée par l'antistyle et le stylifer, ainsi que l'aspect externe qui n'est pas sans ressembler au P. bellieri typique des Alpes". Further, Picard referred to the figures of Reverdin (1915, pl. 5 figs. 5, 6 and 7). Alberti (1967) described the species Pyrgus jupei from the Caucasus, mainly based on the small proportions of the style and antistyle.... |

| The species of Coladenia Moore, 1881, occurring in the Philippines are revised. The following species are shown to occur there: C. igna (Semper, 1892), C. semperi Elwes & Edwards, 1897, C. minor Chiba et al., 1991, and C. palawana (Staudinger, 1889). Two new species are added: C. ochracea and C. similis, and the new subspecies of C. igna marinda, is described. Due to the incorrect identification of the Sundaland form of C. agni (de Niceville, 1883) as the Philippine C. igna by Evans (1949), the former was still unnamed; it is named C. agni sundae here. |

| 1. Geographic variation in the male genitalia of Carcharodus alceae (Esper) Carcharodus alceae is widespread in the Palaearctic region: it occurs from the Sahara to Northern Germany and from Portugal to the Altai, Turkestan and Kashmir, from where it penetrates the Oriental region along the southside of the Himalayas to Mussoree; isolated from its main range it occurs in Southwestern Arabia. Although it is a species of dry and warm localities, such as steppes, sunny slopes, dry meadows, etc., even flying in the semidesert in Morocco, it ascends to 1600 m in the Alps (Kauffmann, 1951). The large range of temperatures thus covered by alceae is reflected by the variation in number of broods per year. In the mountains and north of the Alps there are one or two... |

| The possible zone of contact between Pyrgus (malvae) malvae Linnaeus, 1758, and P. (malvae) melotis Duponchel, 1832, is re-examined. The two taxa apparently meet (in the subspecies malvae and ponticus Reverdin, 1914, respectively) in N. and W. Turkey and possibly in S. Russia north of the Caucasus. There are, however, only few localities or areas from where both are known: Amasya and north of Ankara in N. Turkey and Izmir in W. Turkey. In these areas the two taxa do not seem to recognize each other as belonging to the same species. A population with an intermediate character is known to occur in the Boz Dagh area east of Izmir. The population seems remarkably constant in this character. Its origin is obscure. The available data do not prompt us to change... |

| Three species can be recognized in the Pyrgus alpinus group, viz., alpinus, darwazicus and cashmirensis. They show an interesting geographic variation, so that a subspecies of one species can be very similar to a subspecies of another species, though other subspecies are quite different. The subspecies recognized are described and illustrated. Two subspecies are described as new, viz., Pyrgus darwazicus distinctus and Pyrgus cashmirensis pumilus. Distribution maps and drawings of the male and female genitalia of each species are provided. Although for various characters plesiomorphous and apomorphous states can be distinguished, it is not possible to make a satisfactory choice between the three possible phylogenetic trees of the group. An analysis of the... |

| The belt of lowland forest that stretches from West Africa eastward ends in a number of isolated forests in East Uganda and West Kenya, the most eastern extremity being the Kakamega Forest in the Western Province of Kenya, about 50 km north of Kisumu. Although impoverished as compared with the Congolese fauna, the fauna of these isolated forests is interesting, because much subspeciation has taken place there (Carcasson, 1964). In some cases the isolation appears to have led even to speciation, and below two new species are described from the Kakamega Forest. The former, Celaenorrhinus lourentis, is a member of a wide-spread genus of forest species, most of which (17 out of 23 African species) occur in the Cameroon and Congolese region. The second species,... |

| All species and subspecies of the Hesperiidae known from the Philippines are listed and their distribution across the islands, preferred habitats and flight habits are indicated. By far the richest habitat is the primary lowland forest. In view of the high rate of deforestation it is estimated that 50% of the hesperiid species is endangered and may become extinct over the next 10 to 15 years. With 151 species the Philippines is considerably poorer than Borneo (214 species), but much richer than Sulawesi (84 species). In terms of endemicity, however, the Philippines is with 35 endemic species (23.2%) relatively much richer than Borneo (12 species, 5.6%), and almost as rich as Sulawesi (20 species, 23.8%). The distribution and endemicity of species and... |

| The five known species of the African genus Chondrolepis Mabille are extensively described and figured and two new species are added. Keys are given to the males and females separately. Most species are restricted to montane habitats, mainly in East Africa. Based on their phylogeny the geographic history of the species is analyzed. It is concluded that the distribution agrees with the predictions to be derived from the hypotheses that montane forests were very much restricted during the last Glacial Period of the Northern Hemisphere, later on becoming more widespread than at present, and that the contact between the Cameroun highlands and the highlands of East Africa was through species that temporarily lived in the intervening lowland forests and not... |

| The name Papilio fritillarius Poda, 1761, is shown to be a nomen dubium. It has caused much confusion and has been applied to five or six different species since the first publication and to three different species in the last 40 years. To put an end to the confusion a neotype is designated. For the neotype a specimen has been selected of the species currently known as Pyrgus malvae (Linnaeus), thus making Papilio fritillarius Poda, 1761, a junior subjective synonym of Papilio malvae Linnaeus, 1758. Consequently, Poda's name can no longer be used for the species named Papilio carthami by Hübner, [1813] and now currently placed in the genus Pyrgus. The same species was named Papilio malvae maior by Fabricius (1787) and for reasons of priority Hübner's name... |

| The genus Taractrocera is distributed throughout the Oriental and Australian Regions. It contains 16 species, of which two, T. fusca and T. trikora, are described as new in this paper. All species are briefly characterized and the new species are described in full. The phylogeny of the genus is inferred, based on an analysis of morphological and genital characters, both of males and females. The biogeography of the genus is discussed in relation to the phylogeny. The genus has an Australian origin. After some diversification in Australia it dispersed into Asia, in or before the Miocene. It dispersed in the reverse direction, probably before the late-Miocene emergence of the Banda Arc and the Moluccas, 5-6 Mya. Three species are adapted to high altitude,... |
