Twenty species of Pselaphinae are newly recorded from New Brunswick, Canada. This brings the total number of species known from the province to 36. Thirteen of these species are newly recorded for the Maritime provinces of Canada. Dalmosella tenuis Casey and Brachygluta luniger (LeConte) are newly recorded for Canada. Collection and habitat data are presented for these species.     

Development of the braconid wasp Cotesia flavipes in two Crambids, Diatraea saccharalis and Eoreuma loftini: Evidence of host developmental disruption

Cotesia flavipes is an important gregarious larval endoparasitoid of several crambid stem borers, including Diatraea saccharalis. The suitability of two crambid species, Eoreuma loftini and D. saccharalis, pests of sugarcane and rice in Texas, for C. flavipes development was tested. The effect of parasitization by C. flavipes on encapsulation response was assessed in vivo in both D. saccharalis and E. loftini. The results indicated that the parasitoid developed and emerged successfully in D. saccharalis larvae. Although E. loftini larvae were readily parasitized by C. flavipes parasitoids, no wasp larvae hatched from the eggs in this host because eggs were encapsulated by the host's hemocytes. The developmental fate of the E. loftini larvae with encapsulated parasitoids was variable. Most died as abnormal fifth instars or as post-wandering prepupae, while a few developed normally to the pupal stage. In vivo experiments, there was a significant reduction in the percent of beads encapsulated in parasitized larvae in both hosts. However, the percent of beads showing melanization decreased significantly in parasitized D. saccharalis larvae but did not differ significantly in parasitized or unparasitized E. loftini larvae. Our results showed that D. saccharalis is a suitable host for C. flavipes whereas E. loftini is an unsuitable host. This study indicated that lepidopteran stem borers that are taxonomically, behaviorally, and ecologically very similar can differ in their ability to encapsulate a parasitoid species.     

Two new species of Amblypsilopus Bigot with a key to species from Taiwan (Diptera, Dolichopodidae)

The following two new species of the genus Amblypsilopus Bigot from Taiwan are described: Amblypsilopus flavellussp. n. and Amblypsilopus ventralissp. n. One species, Amblypsilopus crassatus Yang, 1997, is newly reported from Taiwan. A key to the species of the genus from Taiwan is given.     

A new marine gobiid species of the genus Clariger Jordan & Snyder (Gobiidae, Teleostei) from Taiwan

A new species of Clariger Jordan & Snyder, 1901 was collected from northern Taiwan. The genus was previously known only from Japanese waters. This discovery is the first formal and southernmost record of these marine gobies from the waters of subtropical Taiwan. The new species, Clariger taiwanensissp. n., is distinguished from its congeners by a unique combination of features: (1) fin rays: dorsal-fin rays III, I/8; anal-fin rays modally I/8; and pectoral-fin rays modally 19 (2+16+1); (2) longitudinal dermal ridge on head with 6 barbels; and (3) specific coloration pattern: head and trunk dark brown with scattered pale spots and blotches; cheek, ventral portion of head sometimes pale with deep brown spots; pectoral-fin base with a dark brown band; and caudal fin mostly dark brown proximally and with alternating and irregular dark brown and pale bands distally. A diagnostic key to all nominal species from Japan and Taiwan is provided.     

Three new species of Fancy Case caterpillars from threatened forests of Hawaii (Lepidoptera, Cosmopterigidae, Hyposmocoma)

The endemic Hawaiian moth genus Hyposmocoma includes 348 described species and perhaps twice as many that remain undescribed. The genus is unusual within Lepidoptera in that its larvae create distinctive silk cases in which they perambulate while protected and camouflaged. An extraordinary diversity of case types exists, and to date more than ten different types have been identified, each corresponding roughly to a separate evolutionary lineage. In this study, we describe three new species of Hyposmocoma: Hyposmocoma ipohapuusp. n. from Big Island, Hyposmocoma makawaosp. n. from Makawao Forest Reserve in Mauiand Hyposmocoma tantalasp. n. from Mt. Tantalus, Oahu, all of which produce tubular purse cases during their larval stage. We also describe the female of Hyposmocoma inversella Walsingham, which was previously undescribed, and re-describe two closely related species, Hyposmocoma auropurpurea Walsingham and Hyposmocoma nebulifera Walsingham, neither which have been formally described in recent years. We present for the first time, primer sequences for a 705 bp fragment of CAD, designed for Hyposmocoma and relatives. The molecular phylogeny based on mitochondrial and nuclear loci demonstrates that all are distinct species. The discovery of a new, endemic species from Mt. Tantalus, an area with many invasive species, suggests that even relatively degraded areas in Hawaii would be worthy of active conservation efforts.     

Amphipoda (crustacea) from palau, micronesia: families ampeliscidae, ampithoidae, aoridae, colomastigidae and cyproideidae

12 species of amphipod in 5 families, collected from shallow reefs in Palau by S. DeGrave during 2002, are reported here. Of these, five species are new to science and Microdeutopus tridens Schellenberg (1938) is redescribed and transferred to the genus Bemlos Shoemaker (1925). The collection included several additional species in the genera Amphilochus Bate, 1862, Ampithoe Leach (1814), Bemlos, Byblis Boeck (1871), Colomastix Grube (1861) and Notopoma Lowry & Berents (1996), that were either incomplete or juvenile and could therefore not adequately be described. In addition, two new species of Plumithoe Barnard & Karaman (1991) are erected from the literature. Other families collected in Palau will be considered in later contributions.
