Another new amphipod species, Gammarus egmao sp. nov., from Peynirlikönü Cave [Evren Günay Mehmet Ali Özel (EGMA) Cave] was identified. The specimens of the new species were sampled from 350 m inside of the cave entrance. This is the second species identified from the cave in addition to Gammarus ustaoglui Özbek and Güloğlu, 2005. The newly identified species has the following characteristic features: a) small eyes, b) 2- segmented accessory flagellum of antenna II, c) aesthetascs on the flagellar segments of antenna I, d) reduced armaments in distal part of palp of maxilla I e) short inner ramus of uropod III and reduced setation on margins of rami of uropod III. A detailed description of holotype female and illustrations of the appendages were presented. Additionally, differences from the related species were discussed.

A New Species

A new species of freshwater Amphipod, Gammarus topkarai sp. nov., collected from Ivriz Creek, Tarsus Province, South Anatolia, is described and illustrated. The new species belongs to Gammarus pulex-group and shows similar characteristic features with Gammarus agrarius G. S. Karaman, 1973. Absence of well developed dorsal elevations on the urosome segments, smaller body length and relatively lower endopod/exopod ratio of third uropod are the most obvious features differ from G. agrarius. A detailed morphological description and illustrations of new species are given and differences from related species are discussed. An updated identification key of Gammarus taxa reported from Turkey, up to date, was also presented.

The present paper contains descriptions of four new species of the genus Tumicla Wallengren, 1863: T. elephantina sp. nov. (South Mozambique), T. mbeghai sp. nov. (NE Tanzania), T. admiranda sp. nov. (SE Democratic Republic of the Congo) and T. smithi sp. nov. (Central Zambia). The male paratype specimen of T. doa Kühne 2007 is proved to be not conspecific with the holotype female but belongs to an undescribed species described here as T. mbeghai sp. nov. rendering Tumicla doa to be known by the female holotype only. Adults, male and female genitalia of the new and related species are illustrated.

A new amphipod species, Dikerogammarus istanbulensis sp. nov., is described. Specimens were collected from a reservoir, near Silivri district, İ stanbul province, Turkey. The new species is similar to Dikerogammarus bispinosus Martynov, 1925 except for the presence of setae on inner surface of basal segment of pereopod 7 in both sexes and absence of long setae on the ventral side of second peduncle segment of antenna 1. In addition, epimeral plate 2 has many setae along the ventral margin in both sexes. A detailed morphological description and illustrations of the new species are given. Differences between the new species and related species are discussed. An identification key for the genus Dikerogammarus is presented.

A New Species

A new species of the Aeolosomatidae, Aeolosoma vietnamicum sp. n., found in freshwater bodies of Vietnam, is illustrated and described. The new species differs from its congeners in the presence of specific sigmoid chaetae in the dorsal and ventral bundles of all segments, beginning from II. These chaetae are characterized by tips with two apical teeth and an additional row of three to nine distinct denticles on the concave side of the chaetae’s distal part. Aeolosoma vietnamicum sp. n. also differs from closely related species in the length, pattern and number of hair chaetae per bundle.

A New Species

The morphological and morphometric analyses of 88 orbiniids from the continental shelf of the Gulf of California lacking thoracic neuropodial hooks confirmed that a new species, Leitoscoloplos multipapillatus, described herein, is present along with Leitoscoloplos panamensis (Monro. 1933), already recorded there. The new species is closely related to L. panamensis, but can be clearly separated from this, and all other species of Leitoscoloplos, by the unique presence of up to 14 stomach papillae per chaetiger. A third taxon was identified, Leitoscoloplos sp., which is morphologically indistinguishable from L. panamensis, except for the presence of 1-2 stomach papillae on 1-2 segments, a feature that although important was not considered significant enough to erect a new species. Morphometric analyses between the closely related species, L. panamensis (including its type material) and L. multipapillatus sp. nov., in addition to Leitoscoloplos sp., were used to verify the new species. The generic diagnosis is emended to include species with numerous stomach papillae. Anatomical examination of these species was carried out with SEM to illustrate their characteristic features and corroborate the presence of capillary chaetae only along the thorax of the analysed specimens, as well as the unusual occurrence of stomach papillae.

We describe a new species of the Rhacophorus genus, which differs from all species known in Asia by the combination of characters. It strongly differs also from small and middle-sized species of Rhacophorus sensu lato: Rhacophorus calcaneus Smith, 1924, Leptomantis cyanopunctatus (Manthey et Steiof, 1998), Rhacophorus hoabinhensis Nguyen, Pham, Nguyen, Ninh et Ziegler, 2017, Rhacophorus hoanglienensis Orlov, Lathrop, Murphy et Ho, 2001, Zhangixalus jarujini (Matsui et Panha, 2006), Rhacophorus laoshan Mo, Jiang, Xie et Ohler, 2008, Rhacophorus pardalis Günther, 1858, Rhacophorus rhodopus Liu et Hu, 1960, Rhacophorus robertingeri Orlov, Poyarkov, Vassilieva, Ananjeva, Nguyen, Sang, and Geissler, 2012, Leptomantis robinsonii (Boulenger, 1903), Rhacophorus spelaeus Orlov, Gnophanxay, Phimminith, and Phomphoumy, 2010, Rhacophorus translineatus Wu, 1977, Rhacophorus turpes Smith, 1940, Rhacophorus vampyrus Rowley, Le, Thi, Stuart et Hoang, 2010, Rhacophorus viridimaculatus Ostroshabov, Orlov et Nguyen, 2013 by having brown color with two green dorsolateral stripes starting at the groin level and connecting through the distal part of eyelid with green triangle on the head, slender body and head, lower ratio HW/HL 0.86, lower HW/SVL 0.28 and lower ratio HL/SVL 0.32.

Two New Species

This paper continues the publication of new data obtained during field studies in remote and poorly studied regions of Laos in 2015–2018. It provides descriptions of two new species (Bulbophyllum brachyscapum Aver. and Sunipia saccata Aver.), emended descriptions of two previously published but insufficiently known species (Cleisostoma verrucosum Aver., Oberonia vesiculifera Aver.) and reports of eight species newly recorded in the flora of Laos (Biermannia calcarata Aver., Bulbophyllum farreri (W. W. Sm.) Seidenf., Didymoplexiella trichechus (J. J. Sm.) Garay, Eria eriopsidobulbon C. S. P. Parish et Rchb. fil., Habenaria ciliolaris Kraenzl., Liparis caudata Aver. et K. S. Nguyen, Odontochilus umbrosus (Aver.) Ormerod, and Porpax ustulata (C. S. P. Parish et Rchb. fil.) Rolfe). Appropriate citations of regional literature, colour illustrations, data on types and distribution, descriptions, etymology, as well as notes on taxonomy and related species are provided for the studied species.
