The morphology of the first nine zoeal stages of the upper-bathyal caridean shrimp Heterocarpus abulbus Yang, Chan and Chu, 2010 are described and illustrated in detail from laboratory-hatched material. In comparison with previous studies of Heterocarpus larvae, an important progress in larval rearing was achieved, with the larvae surviving in the laboratory for 25 days. Although some adult characters had started to develop, the absence of pleopods at the zoea IX suggests that H. abulbus has an extended planktonic larval phase that likely consists of at least 11 zoeal stages. The larvae of H. abulbus can be readily distinguished from other known Heterocarpus zoeae by the large size of their zoea I and for having four instead of three setae on the first segment of the endopod of the second maxilliped in zoea II and subsequent stages. © 2016 by The Crustacean Society.

Mantodea are very rare in the fossil record. 28 fossil species are reported since the earliest occurrence of mantodeans in the Upper Jurassic (Tithonian). Here, I describe Cretophotina santanensis n. sp. from the Aptian (Lower Cretaceous) Crato Formation of Chapada do Araripe (northeastern Brazil). This species is characterized by long antenna and primitive raptorial forelegs. Morphological characters shared with the living genus Chaeteessa would support its assignment to the family Chaeteessidae. The tropical occurrence of the Early Cretaceous genus Cretophotina in Gondwana, together with occurrences of the genus Chaetessa from subtropical and temperate zones of Laurasia, implies that members of the family Chaeteessidae achieved nearly cosmopolitan distribution during the Early Cretaceous.

The eggs of three deep-sea pandalid shrimps Heterocarpus abulbus, H. hayashii and H. sibogae are successfully hatched in the laboratory. The first zoeal stage of these shrimps are described, with those of H. abulbus and H. hayashii being reported for the first time. First zoeae of different Heterocarpus species can be distinguished by the spination at the anteroventral carapace, body size, rostral length and appendage setation. Copyright © 2014 Magnolia Press.

The first four larval stages of the pandalid shrimp Chlorotocus crassicornis (A. Costa, 1871) are described and illustrated from laboratory-reared material obtained from ovigerous females collected in the southwestern Spain and south Taiwan. The second to fourth larval stages of this species are reported for the first time to science. Detailed examination of the first larval stages reveals that previous description misidentified some key larval characters which have prevented its identification in plankton samples. It is found that the zoeal morphology of Chlorotocus is not very different from other pandalid larvae, and in fact closely resembles Plesionika and Heterocarpus. Copyright © 2015 Magnolia Press.

A new owstoniine bandfish, Owstonia kamoharai, is described based on six specimens (147–402 mm in standard length) collected from off southern Japan: Shikoku Island, Kii Peninsula, and Suruga Bay. The new species differs from its congeners by the following combination of characters: dorsal-fin rays III, 21; anal-fin rays I, 14; pectoral-fin rays 21–23; total caudal-fin rays 17 (branched 13); vertebrae 28–29; gill rakers on first arch 39–40; cheek with 88–123 scales in 8–10 rows; lateral line without branch, not forming loop in front of dorsal fin, ending below 8th–10th dorsal-fin soft rays; scales in longitudinal rows 53–56; lower margin of preopercle smooth; pelvic fin short, not reaching to anus; posterior margin of caudal fin rounded; uniformly reddish coloration with black markings on membranes of both jaws; and white margins of vertical fins. © 2015 The Ichthyological Society of Japan
