A New Species

The male and female of Neotanais krappschickelae n.sp., from the Subantarctic off the Falkland Islands are described from the RV Eltanin deep-water cruises of 1962. Both male and female of the new species can be separated from other species by the combination of characters including: a densely setose dorsal margin of the cheliped carpus, dactylus and fixed finger of subequal length; cheliped sclerite, all pereopodal bases, and posterior-lateral edges of pereonites with numerous plumose setae. The recent activity within tanaidacean taxonomy including neotanaid taxonomy has made it necessary to re-diagnose Neotanais.

A New Species

A new species of the deep-water king-crab genus Neolithodes A. Milne-Edwards & Bouvier, 1894 (Anomura: Lithodidae) is described herein from the southeastern Arabian Sea (1064–1338 m depth). Neolithodes indicus sp. nov. shows morphological proximity with three congeneric species, N. brodiei Dawson & Yaldwyn, 1970, N. flindersi Ahyong, 2010a and N. nipponensis Sakai, 1971 in bearing less numerous secondary spines on the carapace, the dactylus of the chelipeds with a convex dorsal margin and dorsoventrally compressed meri of the pereopods 2–4. The new species can be easily distinguished from these congeners in possessing the less densely spinulose carapace and appendages, short rostrum, simple antennal scaphocerite, the absence of large spines on the flexor margins of the pereopods 2–3 meri, and a stouter pereopod 4 propodus.

Bougainvillia aberrans n.sp. is described from Bermuda in the western North Atlantic Ocean. Specimens were collected at a depth of 150 fathoms (274 m) from the polypropylene buoy line of a crab trap. The hydroid colony of B. aberrans is erect, with a polysiphonic hydrocaulus, a smooth to somewhat wrinkled perisarc, hydranths having a maximum of about 16 tentacles, and medusa buds arising only from hydranth pedicels. Medusae liberated in the laboratory from these hydroids differ from all other known species of the genus in having a long, spindle-shaped manubrium, lacking oral tentacles, having marginal tentacles reduced to mere stubs, and being very short-lived (surviving for a few hours at most). Gonads develop in medusa buds while they are still attached to the hydroids, and gametes are shed either prior to liberation of the medusae or shortly thereafter. The eggs are surrounded by an envelope bearing nematocysts (heterotrichous microbasic euryteles). The cnidome of both hydroid and medusa stages consists of desmonemes and heterotrichous microbasic euryteles. The diagnosis of the genus Bougainvillia is modified to accommodate this new deep-water species.

A New Species

Only three species of Trichomyia Haliday have been recorded in Mexico. Trichomyia cirrata Coquillett, 1902, is recognized by its female characteristics, T. fairchildi Vargas and D az-N jera, 1953, was described based only on the wing and must be considered as species inquirenda, and T. maldonadoi (Vargas, 1953), which was described based on one female specimen. Specimens of Trichomyia collected in the states of Campeche, Yucatan, and Oaxaca, Mexico, allowed this female to be associated with the male of T. brevitarsa (Rapp, 1945), thus providing a first report of this species in Mexico. Consequently, T. maldonadoi is proposed as a synonym of T. brevitarsa. Additionally, a new species of Trichomyia from the state of Veracruz, Mexico, is described and illustrated based on the male and female characteristics.

A New Species

The E. ovina group of species is proposed here to include Edessa ovina Dallas, 1851 from Trinidad and Tobago, Colombia, Paraguay, Brazil, Argentina (new records) and Guyana; E. impura Bergroth, 1891 from Brazil and Argentina (new record); E. sahlbergii Stål, 1872 restricted to Brazil; and E. graziae sp. nov. from Brazil and Argentina. The E. ovina group can be identified by the apex of the second pair of wings narrowing distally and by a tumid area on the ventral surface of the pygophore (male genitalia) projected posteriorly. Descriptions, measurements, and illustrations of the metasternal process, external and internal genitalia of male and female are provided. A map with the distribution of the species is presented. The holotype of Edessa ovina is designated here. Edessa argali Breddin, 1903 is considered a junior synonym of E. impura. Females of E. ovina and E. impura, and male of E. sahlbergii are described for the first time.

High Diversity

Acteonidae d'Orbigny, 1843 is the largest family within the superfamily Acteonoidea (Bouchet et al. 2017) and includes small gastropods typical of infralittoral environments. Most acteonids living on the continental shelf or in deep water have been described on the basis of shell morphology alone (Simone 2006; Valdés 2008; Cunha 2011; Salvador & Cunha 2016), because little material with soft parts has been collected and examined. Consequently, little is known about the ecology of the species.  Recently, many new species of the genus Acteon Montfort, 1810 have been described from tropical Southwest Pacific waters (Valdés 2008), suggesting that a high diversity of acteonid species may await discovery in other deep water environments, including those of Brazil.

A New Species

A new definition for the genus Moribaetis Waltz & McCafferty 1985 is given. Its type species, Moribaetis maculipennis (Flowers 1979) is redescribed based on male and female imagoes reared from larvae near the type locality in Panama. Larvae, formerly wrongly attributed to Moribaetis salvini (Eaton 1885), and a male imago, formerly wrongly attributed to Moribaetis macaferti Waltz 1985, belong to a new species Moribaetis latipennis sp. n., which is described here based on a male imago reared from larva in Panama. Both species, M. maculipennis and M. latipennis sp. n., are distinct from M. salvini, which is known as a single male imago (lectotype) from Costa Rica. All other species, formerly attributed to Moribaetis, are excluded from this genus; a new combination Caribaetis macaferti comb. n. is proposed for the species originally described as Moribaetis macaferti Waltz (in Waltz & McCafferty) 1985, and a new combination Baetis (Rhodobaetis) mimbresaurus comb. n. is proposed for the species originally described as Moribaetis mimbresaurus McCafferty 2007.

A New Species

Pseudolebinthus is an intriguing genus of the tribe Xenogryllini with a distribtuion restricted to southeast Africa and characterized by unique morphological features such as asymmetrical male forewings and harp veins shaped as elongated balloons. It is sister group to the widely distributed genus Xenogryllus and has been known by two species, P. africanus Robillard, 2006 and P. whellani Robillard, 2006. The genus was initially diagnosed based exclusively on male morphological features. In this study, we add a new species to the genus, P. gorochovi Robillard sp. nov. and revise the diagnostic features using both male and female characters. We also update identification keys for the species of the genus.
