Mallomonas voloshkoae sp. nov. was described from Russia based on silica-scale morphology studied by means of transmission and scanning electron microscopy. This species belongs to the section Striatae and is characterised by scales with wide anterior flanges, forming wing-like extensions. This species is most similar in scale ultrastructure to M. pechlaneri. Mallomonas voloshkoae was reported in four mountain lakes of the Transbaikal area and was found in acidic to slightly acidic conditions with very low values of specific conductance. Mallomonas pechlaneri was reported in Russia for the first time. This is the first record of this species after the description of this taxon in Europe. Mallomonas pechlaneri was found in three oligotrophic habitats in the Altay and Sayan Mountain areas.

Mallomonas fimbriata, sp. nov. is described from bog pool, located in Cam Ranh Peninsula, Khanh Hoa Province, Central Vietnam. The description is based on silica-scale morphology studied by means of transmission and scanning electron microscopy. New species has 3 types of scales: oval body scales, caudal ones with robust, long, forward pointing spines and elongated, widened to distal part apical scales. Scales are thick, 3-layered, with inner reticulation. Mallomonas fimbriata and the similar M. fenestrata form a special group with unique features of scales structure close to the sections Retrorsae and Quadratae.

Mallomonas distinguenda sp. nov. and Mallomonas skvortsovii sp. nov. are described from Dak Lua swamp, located in Cat Tien National Park (Dong Nai Province, Southeastern Viet Nam). The description is based on silica-scale morphology studied by means of transmission and scanning electron microscopy. These species belong to the section Papillosae based on scale morphology. The most characteristic feature for both taxa is the shield reticulation. In the case of Mallomonas distinguenda, it is an external reticulation. By contrast, Mallomonas skvortsovii has internal reticulation.

This paper describes the new species Mallomonas papuensis from a small bog pool in Papua province, Indonesia. The description is based on silica-scale morphology studied by means of transmission and scanning electron microscopy. The cells of Mallomonas papuensis are covered by three types of scales: asymmetric collar scales with forward projecting spines, rhombic body scales and oval posterior scales with short spines. The shield of all scales types lacks ornamentation. We were not able to find any specimens with bristles or isolated bristles although the small dome is visible on the collar scales. Mallomonas papuensis belongs to the section Torquatae and closely resembles M. newfoundlandicus. Distinctions from other similar taxa are discussed.

Mallomonas kuzminii sp. nov. is described from an oligotrophic lake located in Russia, East Siberia, Northern Baikal region. The description is based on silica-scale morphology studied by means of transmission and scanning electron microscopy. This new species belongs to the section Mallomonas and has several types of scales with or without dome. The form of the scales, the strongly hooded V-rib, and a dome with ribs surrounded by the extensions of the anterior rib, are the main features which distinguish this new taxon from the other species of the section.

This paper describes two new species of Mallomonas. Mallomonas temonis was identified in the Table Mountain Plateau, South Africa; Mallomonas divida was identified in Aquitaine, France. The descriptions are based on silica-scale morphology studied by means of transmission and scanning electron microscopy. Mallomonas temonis belongs to the section Heterospinae. A scale is surrounded by a submarginal rib connected at lateral parts by a strong, more or less transversal rib. Mallomonas divida belongs to the section Torquatae. The shield of scales is covered by regularly arranged, delicate papillae and marked by one or several rows of more distinctive papillae.

A new species Mallomonas lamii sp. nov. is described from Vietnam based on silica-scale morphology studied by means of transmission and scanning electron microscopies. The species belongs to the Mallomonas matvienkoae complex and is characterized by large oval scales with a thick secondary layer with internal reticulation that covers the distal one-third of the scale. The scale morphology of Mallomonas lamii is very similar to that of the fossil taxon M. pleuriforamen. Scales of Mallomonas lamii were found at thirteen localities from six provinces in central and southern areas of Vietnam. The distributions and habitat conditions of the new species are summarized.

Two new species, Mallomonas punctostriata sp. nov. and Mallomonas collucata sp. nov., are described from Vietnam based on silica-scale morphology studied by means of transmission and scanning electron microscopy. Both species inhabits swamp areas. Mallomonas punctostriata belongs to section Striatae. Its scales have unique transverse rows, consisting of papillae, resembling transverse ribs of members of section Striatae. Mallomonas collucata belongs to section Annulatae. This species has small scales with hexagonal reticulation on the shield. Mallomonas punctostriata was found in Phu Quoc Island (Kien Giang Province) and Cam Ranh Peninsula (Khanh Hoa Province). Mallomonas collucata has been observed only in one site on Phu Quoc Island.
