AbstractCast exuviae from final-instar larvae of four species of hymenopterous parasitoids of Dendroctonus rufipennis (Kirby, 1837) were examined for diagnostic characters. The head capsules of Bracon tenuis Muesebeck and Walkley, 1951, Coeloides rufovariegatus (Provancher, 1880), Roptrocerus xylophagorum (Ratzeburg, 1844), and Dinotiscus dendroctoni (Ashmead, 1894) each displayed unique combinations of characters allowing discrimination among species. Head capsules are illustrated, and a key to species is presented.

A New Species

AbstractAhnea keejeongi Park and Carlton (Coleoptera: Staphylinidae: Pselaphinae), a new genus and new species of New Zealand endemic beetle belonging to the supertribe Faronitae is described. Six previously described species are included to this genus and four species are synonymised as follow: Sagola dissonans Broun, 1921 and S. planicula Broun, 1921 under Ahnea ventralis (Broun, 1912); S. carinata Broun, 1912 and S. lineiceps Broun, 1921 under Ahnea lineata (Broun, 1893). A key to species, habitus photographs, line drawings of diagnostic characters, and distribution maps are provided.

Mangabea troglodytes sp. nov. (Hemiptera: Heteroptera: Reduviidae: Emesinae) is described based on four specimens collected in a cave of the Namoroka Karstic System, Madagascar, and deposited in the Collection of the Muséum National d’Histoire Naturelle, Paris. The dorsal habitus as well as diagnostic characters of male and female genitalia are extensively illustrated and imaged. A key to species of the genus Mangabea Villiers, 1970 is provided and the degree of cave specialization of the new species is discussed.

Formation of Pattern and Diagnostic Instar Features of the Head in Caterpillars from Genus Peridea (Lepidoptera, Notodontidae) Pattern and colouration of caterpillar head of all larval instar of 7 species from genus Peridea Stephens, 1828 are studied. Formation of caterpillar head pattern in ontogenesis is discussed. Diagnostic characters, both specific and larval instars, are recorded for the first time. Key to species according to larval instars is given. Evidently, only larvae of the 1st instar demonstrate different directions in the pattern formation. This characteristic can be used for clearing of taxonomic relations in the genera and on the earliest ontogenetic stages (1st larval instar) only. In the following (2nd-5th) instars, the pattern became more or less of the same type. It depends on stripes shape or colouration only and can serve as good specific diagnostic character. To determine larval instar, both width of the head capsule and head pattern should be taken into account.

The congrid eel genus Conger in Taiwan is reviewed. Five species are recognized, including C. jordani, C. cinereus, C. macrocephalus, C. myriaster and a newly collected species, C. philippinus. A mature male specimen of Conger myriaster is described for the first time. Specimens previously identified as C. japonicus (= C. myriaster) were misidentifications of above mentioned species. The diagnostic characters are discussed. Detailed data on all five species and a key to species in Taiwan are provided.

The male of S. cirrus L. Benick, 1940 was found and illustrated for the first time. A key to species of the cirrus group is provided. All six new species have diagnostic characters of the subgenus Hypostenus. Some species of this group, including S. cirrus, fit the concept of the subgenus Hemistenus.
