Cryptobenthic fauna investigations are highly relevant at studying biodiversity of regions. Studies of the species composition of Gobiesocidae family were carried out in order to clarify ichthyofauna of different regions, and a new species for the Black Sea coastal zone of Crimea was found. Information about its morphology, biology, behavior and other characteristics is very important because of weak study and indeterminate taxonomic status of this species. As a result of morphological studies of the Crimean specimens no significant difference with the type of the Atlantic-Mediterranean populations has been proven. Naturalization of small-headed clingfish in coastal waters of Crimea has been confirmed and some population characteristics, such as a length-weight relationship, have been described. Peculiarities of habitat which which small-headed clingfish prefers and features of localization, enabling competitiveness have been identified. Identification keys were compiled and are given in the paper.

Integrated molecular and morphological studies of newly collected and curated specimens of the genus Caridina from the Atherton Tablelands, Wet Tropics World Heritage Area in north–eastern Queensland, Australia indicated the presence of an undescribed species belonging to the Caridina zebra Short 1993 complex. This species is somewhat intermediate, although distinct on the basis of molecular data and morphology, from two known sympatric species, Caridina zebra and C. confusa Choy & Marshall 1997, and an allopatric species, C. spinula Choy & Marshall 1997, from the Cape York Peninsula, about 500 km north. It is described here as a new species, C. malanda sp. nov., and compared with similar congeners. A key for the identification of the species, as well as notes on its distribution, ecology, and conservation, are provided.

A new species, Selaginella coriaceifolia, is described and illustrated from central Vietnam. The new species can be distinguished from other species in Asia by its habit epilithic, main stem nearly isotomously branched, leaves strongly leathery, ventral leaves imbricate on stem and branch, dorsal leaves with reflexed arista at apex, and sporophylls nearly monomorphic. Molecular and morphological studies of the new species and its allies in S. subg. Heterostachys Baker sect. Heterostachys (Baker) Li Bing Zhang & X.M.Zhou are conducted.

Microcerotermes Silvestri is a cosmopolitan genus and is distributed in all zoogeographical regions, with the exception of the Nearctic. During the study of Iranian termite fauna, specimens of Microcerotermes were collected from Shahroud, Iran. Morphological studies indicated that specimens belonged to a new species. This species comes closest to Microcerotermes varaminicus Ghayourfar, but soldiers differ in possessing darker head-capsule and distinct postclypeus demarcated from frons.

A new species of Paraseison (Rotifera: Seisonacea: Seisonidae) is described from the eastern Pacific Ocean off the coast of California. Female and male specimens of the new species were attached inside the carapace of the leptostracan crustacean Nebalia hessleri, collected at 19 m depth in La Jolla Canyon. This recording represents the first properly identified and described species of Seisonacea for the American coasts. It is furthermore the second known species of the genus Paraseison, which until now included the species P. annulatus only, reported for the Mediterranean Sea and European west Atlantic coast. The new species was diagnosed mostly by its species-specific trophi morphology and in particular by the shape of its fulcrum. Paraseison kisfaludyi sp. nov. is the fourth described species of the order Seisonacea, which accommodates also Seison nebaliae and the recently described S. africanus, all of which live attached to species in the leptostracan genus Nebalia. Even though the Seisonacea are placed in a crucial position within the phylum and may constitute the link between rotifers and other platyzoans, this taxon has in many respects been neglected in morphological studies. Herein we provide new information on the group's taxonomy, morphology and distribution, which will be useful for future phylogenetic and zoogeographical studies.

Stachys babylonica (Lamiaceae). A new species from the mountainous, Kurdistan Iraq, is described and illustrated. Its distinguishing characters are discussed. It is distinguished from the closely related species S. kotschyi by having elliptic-rhombic (vs. ovate or oval- elliptic) leaves, (30-35 x 10-16 mm) (vs. 25-47 x 14-21mm), lower leaves petioles longer ± 16mm (vs. C.7mm), the median leaves petiole ± 7mm (vs. subsessile – sessile), calyx is narrowly tubular appressed (vs. infundibular – campanulate ± spreading), bracteoles are well developed as long as or longer than calyx (vs. shorter than calyx or absent), teeth of calyx are narrowly lanceolate (vs. broadly lanceolate and spreading). This new species to science is represented only by two specimens: the holotype & the isotype #12125.Specimen #12125 has been mistakenly identified as S. tomentosa Rech.f. by Rechinger [1]. Rechinger used only morphological characters in his identification. To clear the ambiguity, Pollen grain study was done and the results of this study were tabulated in Hamodie's work [2] .Specimen #50059 mentioned by Al –Zubaedy [3] as collected by Ali Halob in 2010 from Piera Magron Mt. was also mistakenly identified as S.babylonica. The consideration of specimens belong to S. kotschyi Boiss. as S. babylonica Hamodie & Wilcock made errors on conclusions by Al-Zubaedy [3] on molecular & P.G and morphological studies and reconsideration on these issues are needed. All the indicators so far gathered, approve that plants of this new species were most likely vanished from Piera Magron Mt. in Sulaimaniya sometime after 1948.

The status of the genus Neorthostigma Belokobylskij, 1998 is re-established as a result of additional morphological studies. A new species, N. braetisp. nov., from Papua New Guinea is described and illustrated. Aspilota brachyclypeataFischer 1978 is transferred to Neorthostigma, hence N. brachyclypeata (Fischer, 1978), comb. nov. A new synonym is suggested, Aspilota macrops Stelfox & Graham, 1951 = Neorthostigma eoum Belokobylskij, 1998, syn. nov.; A. macrops is transferred to Neorthostigma. This genus is additionally recorded in the Western Palaearctic (Norway) and Australasian (Papua New Guinea) regions for the first time. A key for the determination of the three known species of Neorthostigma is provided.
