A total of 128 birds of 19 species were parasitised with 17 species of Myrsidea. Descriptions and illustrations are given for four new species of Myrsidea. These new species and their type hosts are: Myrsidea bidentata ex Piranga bidentata (Cardinalidae), M. dolejskae ex Arremon brunneinucha (Emberizidae), M. roubalovae ex Ramphocelus sanguinolentus (Thraupidae), and M. rubica ex Habia ru-bica (Cardinalidae). Records of new host-louse associations are: Chlorospingus ophthalmicus (Emberizidae) and Eupho-nia hirundinacea (Fringillidae) for M. violaceae, Ramphocelus costaricensis (Thraupidae) for M. fusca, and Tangara dowii (Thraupidae) for M. bonariensis. Records of ten other louse species of the genus Myrsidea from birds belonging to these families are also presented and discussed.

New synonymy is proposed for Epyris afer (Magretti, 1884): Epyris pilosipes Ki-effer, 1904, syn. nov.; Epyris analis Kieffer, 1905, syn. nov.; Epyris secundus Brues, 1906, syn. nov.; Epyris rugicollis Cameron, 1906, syn. nov.; Epyris plurilineata Turner, 1928, syn. nov. Two new species Epyris enerterus Stein & Azeve-do, sp. nov. (Myanmar) and Epyris penatii Stein & Azevedo, sp. nov. (Sudan) are described and illustrated. Epyris afer (Magretti) is newly recorded from Yemen, United Arab Emirates, Thailand, and Vietnam.
查看更多>>摘要：Lichenodraculus matti gen. et sp. nov. is described, along with its conspicuous diurnal calling song and some aspects of its interesting ecology and life history. The song allowed a complete acoustic assessment of the altitudinal distribution of this otherwise very cryptic canopy-dwelling insect. The nymph perfectly mimics epiphytic lichens growing in the same elevation range, and apparently the downside of this camouflage is a strictly lichenous diet.
查看更多>>摘要：The genus Capicua Navas, 1921, synonymised with Geyria Esben-Petersen, 1920 by Stange (2004), is reinstated and re-described. The unique specimen of Capicua fitlvicauda Navas, 1921 kept in the Museum d'Histoire Naturelle, Paris is designated as lectotype. Two new species of antlions from West Africa are described and tentatively included in Capicua pending more material of the type species C.fulvicauda to verify this placement. Holotypes and paratypes are deposited in the collection of CIRAD/CBGP inMontpellier, France.
查看更多>>摘要：Baetidae is one of the most diverse families of Ephemeroptera. In South America this family now encompasses 27 genera and more than 130 species. The Guyana region is known for its extraordinary diversity and high level of endemism, which is, above all, remarkable at the tops of the isolated flat-topped table mountains - tepuis. Recently various international speleological expeditions to Churi-tepui explored the cave systems of this mountain. Here we describe a new genus of Baetidae recently found during the mentioned expeditions to Churi-tepui and Auyan-tepui. Parakari n. gen. can be distinguish from the other genera of this family, among other characters, in the nymphs by the absence of abdominal gills I, tarsal claws with subapical denticle largerthan the others, right mandible with prostheca bifid and pectinate and with incisors positioned in obtuse angle to mola area, lingua with a tuft of setae, segment II of maxillary palpi with a concavity and a hole apically and segment II of labial palpiwith a strong distomedial projection. In the adults the hind wings are absent and genitalia with segment II of forceps with a constriction, segment III elongate and long. Two new species are included in this genus; each one was collected at different tepui. A key and illustrations are included.
查看更多>>摘要：A new species of hangingfly, Bittacus coheri, is described from the eastern Terai of Nepal. The male of this species differs from all other known south Asian hangingflies by the presence of a bifurcated flap-like structure between the male epiandrial lobes of tergum 9. Bittacus taraienseis Penny is placed in synonymy with B. indicus Walker, leaving south Asia (Iran to Bangladesh) with six species of hangingflies: at least two with West African affinities and at least two with oriental affinities. Additional records of B. nodosus and B. henryi are given.
查看更多>>摘要：Ditrysia are the largest lepidopteran clade comprising about 99% of the order's species richness (Kristensen & Skalski 1998). Currently, the group is classified into three superfamilies (Tineoidea, Gracillarioidea, and Yponomeutoidea) plus the large clade Apoditrysia (van Nieukerken et al. in press). A number of 20th century authors have studied morphological features of the second abdominal sternum (sternum II) in Ditrysia, particularly how the various sternal processes articulate with the metathorax (e.g., Borner 1939; Brock 1968, 1971; Kyrki 1983; Minet 1983, 1991). In the clade Apoditrysia, sternum II is highly modified, and this structure is considered the principal morphological synapomorphy supporting the monophyly of the clade (review: Kristensen 2003; see below for details).
