Ricamela lata gen. et sp. nov. is described from the state of Bahia in Brazil based on a single female from L. Melichar’s collection in the Moravian Museum, Brno, Czech Republic. The new genus belongs to the subfamily Pharsalinae Gnezdilov of the family Ricaniidae Amyot et Serville and represents the third genus of this group. The systematic position of the American Ricaniidae are discussed. A key to genera of Pharsalinae is given.

Two new species of alvinocaridid shrimps are described from a hydrothermal vent field off northeastern Taiwan at depths of 252–300 m. Alvinocaris chelys n. sp. is morphologically very similar to A. williamsi Shank & Martin, 2003 from the Mid-Atlantic Ridge, and A. alexander Ahyong, 2009 from the southern Kermadec Ridge. These three species can be differentiated by the shape of the postrostral ridge, telson, the second segment of the antennular peduncle and the armature of the meri and ischia of the third pereopod. The second new species, although rather similar to Alvinocaris niwa Webber, 2004 from the Kermadec-Arc, is assigned to a new genus Alvinocaridinides gen. nov., which appears to be intermediate between Shinkaicaris Komai & Segonzac, 2005 and other derived genera including Opaepele Williams & Dobbs, 1995, Chorocaris Martin & Hessler, 1990 and Rimicaris Williams & Rona, 1986. Alvinocaridinides formosa n. sp. differs from Alvinocaris niwa by completely lacking any armature on the ischia of the third to fifth pereopods and by bearing two movable spines at the posterolateral angle of the uropodal exopod. These records constitute the first discovery of the family Alvinocarididae in Taiwanese waters and represent the shallowest occurrence for alvinocaridid shrimps.

Diaphoromyrma sofiae, new genus and new species, is a Myrmicinae ant described from workers from the State of Bahia, Brazil. This taxon is characterized by the following traits: Antenna 9-segmented with 2-segmented club, trapezoidal promesonotum in dorsal view, propodeal spiracles situated on the propodeal edges, and the fourth abdominal sternite with a pair of rounded recurved anterolateral extensions which curve up onto the dorsal surface of the segment. Apparently this ant is close to the genera Allomerus and Diplomorium in the Solenopsidini, but its tribal attribution remains difficult because of the inadequate resolution of the phylogenetic relationships within the Myrmicinae.

Molecular Studies

Morphological and molecular studies in the family Loricariidae have revealed that the relationships among its membersare not yet well resolved, and the present study was conducted with the main objective of improving our knowledge aboutthis highly diversified group of catfishes. Maximum parsimony and Bayesian analysis were conducted on a matrix of 53terminal taxa and 4676 characters with partial sequences of the genes COI, CytB, 16S rRNA, 12S rRNA and F-reticulon4. As outgroups, samples of the species Hemipsilichthys gobio and H. papillatus (subfamily Delturinae), Rineloricariajaraguensis (subfamily Loricariinae), Hypostomus nigromaculatus (subfamily Hypostominae), Hypoptopomainexpectatum (subfamily Hypoptopomatinae), and Corumbataia cuestae (subfamily Otothyrinae) were used. The resultsshowed that the subfamily Neoplecostominae is monophyletic, including Pseudotocinclus, and three clades wererecognized. The first one is composed of Pareiorhina rudolphi, P. cf. rudolphi and Pseudotocinclus. The second iscomposed of Isbrueckerichthys, Pareiorhaphis, Kronichthys and Neoplecostomus ribeirensis. The third is composed ofthe remaining species of the genera Neoplecostomus, except N. ribeirensis, Pareiorhina carrancas, P. cf. carrancas,Pareiorhina sp. 1 (possible new species) and an undescribed taxon referred to in this paper as new genus and species 2. In our analyses, Pareiorhina and Neoplecostomus are paraphyletic taxa.

A new genus of terebellid polychaetes is described, from material collected from living colonies of a stony coral (Mussismilia hispida) in the State of São Paulo, south-eastern Brazil. Articulatia is characterized by possessing notopodia from segment 5, neuropodia from segment 5 or 6 with double rows of uncini from segment 7 until near pygidium. Up to segment ten, notopodia with bilimbate capillaries; from segment 11 onwards two types of notochaetae are present, articulated chaetae, due to a deep cut at the sulcus of the third tooth, as well as capillary chaetae, both types with serrated blades. The presence of deep-cut chaetae is unique among all previously described terebellomorph polychaetes. This new genus is compared with other terebelline genera, and the phylogenetic analysis previously performed for the group is rerun, in order to determine the position of Articulatia within the subfamily. The type species of the new genus, A. aberrans, is also new to science and herein described.

Kotumsaridae, a new family of amphipod crustaceans is described from Kotumsar Cave in the state of Chhattisgarh, India. The family is based on Kotumsaria bastarensis, new genus and species, which is the only known member of the new family recorded to date. Although the new family appears to share some morphological characters with several other taxa from the southern hemisphere considered members of the superfamily Crangonyctoidea, including the New Zealand endemic genus Paracrangonyx, both its taxonomic and phylogenetic affinities remain unclear. Specimens of the new taxon, measuring just over 2 mm in length, were collected from the sediments of a pool in Kotumsar Cave but are believed to have migrated from deeper interstices. Kotumsaria bastarensis is only the third subterranean amphipod recorded to date from the Indian subcontinent.

A New Species

A new species of microhylid frog of the genus Gastrophrynoides is described from Gunung Besar Hantu, in the state of Negeri Sembilan, adding a new generic record to the family Microhylidae of Peninsular Malaysia and an additional species to the previously monotypic genus Gastrophrynoides. This new species can be distinguished from its only congener, G. borneensis by having an immaculate, grayish brown dorsum (instead of a spotted one); a longer snout (2.6–3.0 vs. 2.0–2.5 times diameter of eye); and a single, large, oval outer metacarpal tubercle beneath the hand (instead of smaller, paired, rectangular outer metacarpal tubercles in G. borneensis).

It is the third genus of the family Caraboacaridae in the world. The new genus represents a combination of shared character states with the two previously described genera. An illustrated key to world genera of the family is provided. Differentiation of the new genus from other genera and distribution and host range of all known genera and species of the family are discussed.

Two New Species

Leaves of three species belonging to the family Araucariaceae are described from two Eocene localities in Tasmania. Araucarioides gen. nov. is proposed to contain the fossil species. The erection of a new genus is necessary for two reasons. Two new species, A. linearis and A. sinuosa, are intermediate between Agathis and Araucaria and do not have the Florin rings which are the characteristic of extant species of Araucariaceae. The third new species, A. annulata, while clearly belonging to the Araucariaceae, is not well enough preserved to be assigned to an extant genus. These species confirm the presence of the subtropical/tropical Araucariaceae in Tasmania in the Eocene. The evolutionary position of the fossil species is uncertain at present.

The family Microstigmatidae is composed of two subfamilies, Microstigmatinae and Micromygalinae, seven genera and 16 species. Micromygalinae is monotypic, comprising the species Micromygalediblemma Platnick & Forster, 1982 from Panama. A new genus, Tonton is described as a new member of the Micromygalinae. Masteriaemboaba Pedroso, Baptista & Bertani, 2015, is transferred to the new genus and six new species from Brazil are described and attributed to Tontongen. n.: the type species, T.itabiritosp. n., T.quecasp. n., T.matodentrosp. n. and T.sapalosp. n., all from the state of Minas Gerais; T.ipiausp. n. from the state of Bahia and T.quiteriasp. n. from the state of Maranhão. Among the cavernicolous species, only T.itabiritosp. n. is considered troglobitic by the total absence of eyes.
