The paper describes a fossil wood identifiable as Burseroxylon baranesis from Bara formation of Sindh, Pakistan. Three dimension sections (transverse, radial and tangential) were prepared from the fossil wood collected from Bara formation, Ranikot. The anatomical characters such as presence of growth rings, parenchyma scanty, paratracheal, vasicentric. Rays are homogenous rays consist of procumbent cells indicate that the species belong to the family Burseraceae of petrified Bursera wood and are assigned name as Burseroxylon on the basis of form genus. This is the first record of genus Burseroxylon from tertiary rocks of Pakistan. Presence of diffuse porous wood indicate that the plants were growing in tropical type of climate.

The family Tischeriidae is recorded from Madagascar for the first time. Coptotriche alavelona Lees and Stonis, sp. n., is described from high elevation tropical moist forest of Madagascar, and its proposed generic placement discussed. DNA of this species has been extracted and conserved for future phylogenetic or barcoding studies. The external features and male genitalia are figured and described. An updated checklist and a distribution map for all 13 Tischeriidae species currently recorded from the Afrotropics are provided.

Herein two new species of the genusSyngastesMonard, 1924 are described from South Korea, with detailed descriptions and illustrations. Both new copepods,Syngastesmulticavussp. nov. andS. pseudofoveatussp. nov., have two inner setae on the first exopodal segment of P2 and P3.Syngastesmulticavussp. nov. most closely resemblesS. gibbosusBartsch, 1999 reported from Australia, as they both have a five-segmented antennule in the female. However,Syngastesmulticavussp. nov. has a rounded body outline instead of the gibbose outline observed inS. gibbosus.Syngastespseudofoveatussp. nov. resemblesS. foveatusBartsch, 1994 in almost all aspects. However, they differ clearly in the number of setae on the first exopodal segment of P2 and P3. We also provide a key to species of the genusSyngastesworldwide. The present study is the first record of the family Tegastidae in Korean waters.

A species of the genus Isoperla Banks, 1906, I. oncocauda Huo & Du, sp. nov. is described as new to science and is the first record for the family Perlodidae from the Tianmu Mountain Nature Reserve, Zhejiang Province of eastern coastal China. Both sexes of the new species are characterized by tergum 10 with a developed process. The partially extruded aedeagus of the male is membranous without conspicuous larger sclerites and with the ventral surface covered with dense scale-like and nail-shaped spines.

The coccidian Caryospora bigenetica was first described in the snake Crotalus horridus (Viperidae) from United States of America. This study represents the first record of the occurrence of C. bigenetica in snakes in South America. Feces were sampled between November 2013 and May 2014 from 256 wild snakes maintained in scientific breeding facilities in the states of Mato Grosso do Sul (MS; n = 214) and Rio de Janeiro (RJ; n = 42), Brazil. Caryospora bigenetica was found in 14 (5.6%) snakes, all belonging to the family Viperidae. Ten Bothrops moojeni and two Crotalus durissus from MS were infected. The coccidian was also found in one C. durissus and in one Bothrops jararacussu from the state of RJ. The oocysts were spherical with a double wall, the exterior lightly mammillated, striations apparent in transverse view, 13.0 µm (12 – 14); polar granule fixed in the internal wall. Sporocysts oval or pyriform, 10.0 × 8.0 µm (9 – 11 × 8 – 9); Stieda body discoid; sub-Stieda body present; sporocyst residuum present, formed by a group of spheroid bodies between sporozoites. This study increases the number of viperid hosts of C. bigenetica and expands the geographical distribution to South America.

The record of the fossil representatives of the family Juliidae is updated. The new genus Candinia is proposed, in the subfamily Juliinae, for two fossil species somewhat intermediate between Julia and Berthelinia. The new species Candinia pliocaenica is recorded from the lower Pliocene shallow marine deposits near Siena (Tuscany, Italy). This is the first record of Sacoglossa in the Mediterranean Basin. Based on the very specialized life habits of the Juliidae, it is suggested that subtropical Caulerpa algal prairies inhabited the Mediterranean during the early Pliocene, likely becoming extinct in this basin because of the mid-Pliocene climatic deterioration.

In a survey on the edaphic mesostigmatic mites in mangrove forests of Qeshm Island, eastern of the Persian Gulf, two species of the family Ascidae were collected in broken cockleshells and sand in littoral zone: Leioseius sepidehae sp. nov. and Protogamasellus mica (Athias-Henriot, 1961). This is the first record of the genus Leioseius from Iran. Leioseius sepidehae sp. nov. is described from adult females. Intraspecific variations of some characters of P. mica are discussed, and based on those, P. primitivus machadoi Genis, Loots & Ryke, 1967 and P. primitivus similis Genis, Loots & Ryke, 1967 are herein synonymized under P. mica. Finally, the occasional presence of the gland pores gv1 in Ascidae is reviewed, and a key to the Iranian genera and species of Ascidae is presented.

The Myristicaceae is a member of the early diverging angiosperm order Magnoliales; however, the family is poorly represented by fossil collections. We describe Virola dominicana sp. nov. (Myristicaceae), the first record of fossilized Myristicaceae flowers, from mid-Tertiary (45–15 million years ago) Dominican amber. The description is based on 24 male flowers in 17 pieces of amber, thus providing some indication of intraspecific variation, including a two-tepaled flower. Diagnostic characters of the new species are the long-simple or few-branched trichomes on the perianth margins, the small pollen grains, and a short staminal column. These fossils also show co-occurring insects, some of which could be Virola pollinators. It is speculated that V. dominicana disappeared from Hispaniola during the Pliocene–Pleistocene cooling events leaving no native members of the Myristicaceae in this region today. Additionally, these fossils demonstrate that Myristicaceae was present in the Western Hemisphere during the mid-Tertiary.

A new genus of lichenized fungi of the family Porinaceae is described, known from Costa Rica and Brazil. Flabelloporina Sobreira, M. Cáceres & Lücking is a thus far monospecific genus with an isolated position of its only species in the family, morphologically different from all other genera in Porinaceae. The genus is characterized by the production of numerous, flabelliform squamules on the surface of the thallus, together with black perithecia and transversally septate ascospores (with three septa in the only species). The new combination Flabelloporina squamulifera (Breuss, Lücking & Navarro) Sobreira, M. Cáceres & Lücking is proposed, based on Porina squamulifera Breuss, Lücking & Navarro, and the species is for the first time reported from Brazil.
