    Notes: Abstract Information processing in the olfactory pathway underlying the perception of semiochemicals by insects is discussed. Both the chemical message for mates and the message for food consist of blends of chemicals. Olfactory receptors in an insect species are tuned to the detection of those compounds which comprise such chemical messages for that species. The classification of receptors as specialists or generalists coincides with two concepts of information processing, i.e., labeled lines and across-fiber patterns, respectively. The olfactory code coming from antennal receptors inPieris brassicae larvae is a combination of labeled lines and across-fiber patterning. When antennae of adult Colorado potato beetles,Leptinotarsa decemlineata, are stimulated by binary mixtures of leaf odor components, the pattern of neural activities in the olfactory receptors shows some separation into two channels, quantitative versus qualitative detection. The separation is complete in the antennal lobe of this beetle.

    Phylogeny and biogeography of the genus Taractrocera Butler, 1870 (Lepidoptera: Hesperiidae), an example of Southeast Asian-Australian interchange (2004)
    In:  Zoologische Mededelingen (00240672) vol.78, 18-28 (2004) p.383
    Details
    Publication Date: 2007-01-18
    Description: 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, one in the Himalayas and two in New Guinea. Apparently the adaptations occurred independently in the two areas. In New Guinea the high altitude species may have simply been carried up by the Pleistocene and recent uplift of the mountains. Possibly helped by the lowering of the sea-level several times during the Pleistocene, one Australian species colonized some of the Lesser Sunda Islands relatively recently.

    Notes on the genus Pirdana Distant, 1886 (Lepidoptera: Hesperiidae) (1993)
    In:  Zoologische Mededelingen vol. 67 no. 8, pp. 127-136
    Details
    Publication Date: 2024-01-12
    Description: In the Oriental genus Pirdana Distant, 1886, the new species P. fusca is described from Samar (E Philippines). The phylogeny of the genus is discussed and as a consequence the endemic Sulawesi taxon P. hyela ismene (Felder & Felder, [1867]) is given back its species rank, bringing the total number of species in the genus to five. A key to the species is added.

    Superspecies Pyrgus Malvae (Lepidoptera: Hesperiidae) in the East Mediterranean, with notes on Phylogenetic and Biological relationships (1987)
    In:  Zoologische Mededelingen vol. 61 no. 34, pp. 483-500
    Details
    Publication Date: 2024-01-12
    Description: 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 our view on the superspecies status of Pyrgus (malvae). Notes are added on the apparent incongruence of phylogenetic and biological relationships in this case. P. (malvae) melotis is widely distributed in Turkey, extending east to N. Iran, north to north of the Caucasus and south to Israel. Old records of melotis from Greece or the Aegean islands are highly improbable and should be omitted from further literature records. On the basis of external characters two subspecies are distinguished: melotis and ponticus.

    A note on three species of Taractrocera Butler (Lepidoptera: Hesperiidae) (1991)
    In:  Zoologische Mededelingen vol. 65 no. 19, pp. 257-265
    Details
    Publication Date: 2024-01-12
    Description: Three similar looking species of Taractrocera, generally known as ziclea Pl\xc3\xb6tz, archias Felder and alinea Plotz, are re-examined and existing confusion is clarified. As a consequence, the correct name for the first species is shown to be T. luzonensis (Staudinger), and for the last species T. nigrolimbata (Snellen). The name Thymelicus ziclea Pl\xc3\xb6tz turned out to be a junior synonym of Pamphila archias Felder. Diagnostic characters are given to separate the three species, and the geographic variation is surveyed.

    Revisional notes on Coladenia Moore, 1881 (Lepidoptera: Hesperiidae) (1992)
    In:  Zoologische Mededelingen vol. 66 no. 15, pp. 283-293
    Details
    Publication Date: 2024-01-12
    Description: 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.

    Systematics, Phylogeny and Biogeography of the chiefly Afromontane Genus Chondrolepis Mabille (Lepidoptera : Hesperiidae) (1986)
    In:  Zoologische Verhandelingen vol. 231 no. 1, pp. 1-40
    Details
    Publication Date: 2024-01-12
    Description: 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.\nMost 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 through a continuous belt of montane forest across the African continent. There are indications that for Chrondrolepis this contact was possible twice. Similarly, but at other periods, a contact between the montane habitats of East Za\xc3\xafre and Southeast Tanzania may have occurred twice.\nWhile the diversification of the genus is closely linked with the history of the montane forests, the origin of the genus is supposed to be the result of the desiccation of the Limpopo Valley.\nTesting of this hypothesis by studying the phylogeny and biogeography of other groups which should have been influenced in the same way, could lead to a better understanding of the origin of the South African fauna of forests and forest margins.
