Three barracudina species are recognized in the Stemonosudis rothschildi species complex, which includes Stemonosudis rothschildi Richards, 1967, and two new species described herein. Stemonosudis multifasciatus sp. nov. is described based on five specimens collected off northwestern Australia and Myanmar, Eastern Indian Ocean. It is characterized by having 16 brownish blotches on dorsum (10 before dorsal-fin origin); 49–51 caudal vertebrae; 93‒95 total vertebrae; dorsal-fin origin relatively forward in position, distance between origins of pelvic and dorsal fins 52.3‒63.0% of distance between origins of pelvic and anal fins; and combination of body proportions. Stemonosudis retrodorsalis sp. nov. is described based on 15 specimens collected from off the Philippines, Indonesia and northwestern Australia. It is characterized by having dorsal-fin origin at about vertical through anal-fin origin, insertion of anal fin relatively forward, preanal length 71.5‒79.5% SL; 6 blotches on dorsum before DFO and 4 on abdominal ridge before VFO and unique combination of body proportions. A redescription of S. rothschildi, based on specimens collected from off Dongsha (Pratas) Islands, Australia and West Indies, is also included.

Three New Species

Three new species of the genus Lestidium with complete lateral line are described from the Indo-west Pacific Ocean. Lestidium longilucifer sp. nov., from Western Australia and Taiwan, belongs to the Lestidium atlanticum species complex and can be separated from other congeners by having 41–43 prehaemal vertebrae, 85–88 total vertebrae and 126–146 total lateral-line scales; and body proportions. Lestidium australis sp. nov. from eastern Australia and Lestidium rofeni sp. nov. from Taiwan and the Philippines together with Lestidium prolixum form the L. prolixum species complex. These three species can be separated from each other by a combination of different fin positions, vertebral formula, number of lateral-line scales and pigmentation.

Two genera of barracudinas with luminescent duct in abdominal cavity, Lestrolepis and Lestidium, collected from around Taiwan are studied. Two species in each genus are recognized in Taiwan, including one new species in each genus. New diagnostic characters are used to distinguish these species. Lestrolepis nigroventralis sp. nov. is similar to Lestrolepis intermedia and can be distinguished by having 32–35 prehaemal vertebrae; dorsal-fin origin slightly in front of midline of distance between origins of pelvic and anal fins, distance between origins of dorsal and pelvic fin 9.8–11.7% SL; and pelvic-fin origin at or slightly behind midline of body, prepelvic length 50.6–52.6% SL. Lestidium orientale sp. nov. is similar to Lestidium atlanticum and can be distinguished by having prehaemal vertebrae 37–40; caudal vertebrae 41–44; a relatively short and deep head, reflected by a shorter snout (9.7–10.4% SL), shorter upper jaw (8.6–10.1% SL), shorter lower jaw (11.9–13.7% SL) and a deeper head (31.2–33.9% HL). Data of Lestrolepis japonicus and Lestidium prolixium collected from Taiwan, as well as two Atlantic congeners, are provided. DNA barcoding is conducted to support the recognition of these new species.

The Torodora new species are easily distinguished from congeners by having dark-fuscous wings with various sizes of whitish costal patches or the orange-white wings and body. Illustrations of adults and genitalia for the new species are provided, as well as keys to the species for each the two species-complexes.

Two New Species

Margyricarpus pinnatus is a poorly understood entity from natural grasslands of South America that it better considered as a species complex. In this work we contribute to the advancement of the taxonomic knowledge of this challenging species complex by describing two new species of Margyricarpus from southern Brazil. We present field photographs, illustrations, a distribution map and ecologic and conservation notes on the new species.

A New Species

Microglanis carlae, new species, is described from the río Paraguay basin and distinguished from its congeners by the following combination of characters: paired and anal fins mottled or with thin faint bands, trunk with dark-brown saddles, anterior margin of pectoral spine with serrations retrorse proximally and antrorse distally, tip of pectoral spine as a distinct bony point, continuous portion of lateral line reaching vertical through last dorsal-fin ray, caudal peduncle with irregularly shaped, faint to dark blotch, maxillary barbel surpassing vertical through dorsal-spine origin, and dark bar on posterior flank continuous from base of adipose fin to that of anal fin. The new species is included in the Microglanis parahybae species complex on the basis of color pattern.

Two new species of Hyphessobrycon are described from the upper rio Tapajós basin, Mato Grosso, Brazil. Hyphessobrycon melanostichos is distinguished from its congeners by the combination of a conspicuous longitudinal broad black band beginning on the posterior margin of orbit and reaching the tip of middle caudal fin rays, a distinct vertically elongate humeral spot, and 16 to 18 branched anal-fin rays. Hyphessobrycon notidanos is distinguished from its congeners by the combination of an elongate dorsal fin in mature males, a vertically elongate humeral spot, 2-4 maxillary teeth, iii,8 dorsal-fin rays, and 16 to 21 branched anal-fin rays.

Two new nasal mites of the genus Ptilonyssus Berlese and Trouessart, 1889 are described from sparrows of the genus Passer (Passeriformes: Ploceidae) found in the Leningrad province, Russia: Ptilonyssus degtiarevae, n. sp. from Passer domesticus (L.) and Ptilonyssus lovottiae n. sp. from Passer montanus (L.). Ptilonyssus degtiarevae, n. sp. belongs to the newly established orthonychus species complex, and Ptilonyssus lovottiae n. sp. is referred to the hirsti species complex. The species content of the hirsti complex0, originally defined by Fain and Bafort 1963 is enlarged comparing to the concept of previous researchers.
