ABSTRACT
Two haemogregarine "species" names, Haemogregarina tarentannulari and Haemogregarina rawashi, were cited by Saoud et al. (1995) as having been described by Mohammed and Ramadan (1996, in press). However, the paper by Mohammed and Ramadan (1996) was never published and, therefore, these names and their authorities must be suppressed because they violate Chapter 3 (Criteria for Publication), Article 8 (What Constitutes Published Work) of the International Code of Zoological Nomenclature. The following new names are introduced to replace them based on the Principle of Priority (Chapter 6, Article 23, 23.1, and Chapter 11, Article 51, Recommendation 51E): Hepatozoon rawashi (Mohammed and Ramadan in Saoud, Ramadan, Mohammed and Fawzi, 1995) n. comb., with gamonts in the erythrocytes and meronts in the lungs and liver of the fan-footed gecko, Ptyodactylus hasselquisiti (Donndorff, 1798) from Egypt, and Haemogregarina tarentannulari (Mohammed and Ramadan in Saoud, Ramadan, Mohammed and Fawzi, 1995), with gamonts in the erythrocytes and meronts in the lungs and liver of the white-spotted wall gecko, Tarentola annularis (St. Hilaire, 1827) also from Egypt. This latter species was determined to be a junior synonym of Haemogregarina annularis El-Naffar, Mandour, and Mohammed 1991, which was later reassigned to the genus Hepatozoon based on their phylogenetic analysis of 18S rDNA gene sequences.

There are two predominant sources of taxonomically useful morphological variability in the diverse tardigrade family Echiniscidae: the internal structure and surface sculpture of the cuticular plates covering the dorsum (sculpturing) and the arrangement and morphology of the trunk appendages (chaetotaxy). However, since the appendages often exhibit intraspecific variation (they can be reduced or can develop asymmetrically), sculpturing has been considered more stable at the species level and descriptions of new echiniscid species based solely on morphology are still being published. Here, we present a case study in which a detailed analysis of the morphology and multiple genetic markers of several species of the genus Viridiscus shows that cuticular sculpture may also exhibit considerable intraspecific variation and lead to false taxonomic conclusions. In a population collected from the eastern Nearctic, in the type locality of the recently described species V. miraviridis, individuals with transitional morphotypes between those reported for V. viridissimus and V. miraviridis were found. Importantly, all morphotypes within the viridissimus-miraviridis spectrum were grouped in a single monospecific clade according to rapidly evolving markers (ITS-1, ITS-2 and COI). Given the morphological and genetic evidence, we establish V. miraviridis as a junior synonym of V. viridissimus. This study explicitly demonstrates that a lack of DNA data associated with morphological descriptions of new taxa jeopardizes the efforts to unclutter tardigrade systematics. Additionally, V. perviridis and V. viridissimus are reported from Lâm Dong Province in southern Vietnam, which considerably broadens their known geographic ranges.
ABSTRACT
In 1901, Forel described an ant species from a relatively poorly known genus of ants from North America, naming it Strumigenys pilinasis. In 1931 M. R. Smith obtained the holotype and redescribed it, and he included a first illustration. The description was incomplete and the illustration resembled Strumigenys brevisetosa Smith, 1935, more than it resembled S. pilinasis, which led subsequent taxonomists to make consistent misidentifications and to consider S. brevisetosa to be a synonym of S. pilinasis. Here I redescribe both S. pilinasis and S. brevisetosa (revived status). Strumigenys manni Wesson Wesson, 1939, and S. ohioensis Kennedy Schramm, 1933, are new junior synonyms of S. pilinasis, and S medialis Kennedy Schramm, 1933, is a new junior synonym of S. brevisetosa.

One of the most northern representatives of the family Atyidae, an amphidromous shrimp Paratya borealis Volk, 1938 (Crustacea: Decapoda: Atyidae), is considered as a junior synonym of Paratya compressa (De Haan, 1844 [in De Haan, 1833-1850]) based on morphological and genetic investigations of the specimens collected in rivers flowing into Peter the Great Bay and Posyeta Bay along the Russian coasts of the Sea of Japan. The study greatly increases the area of distribution of P. compressa to north for more than 1000 km and suggests that the species probably inhabit rivers flowing into the Sea of Japan also along North and South Korean coasts.

As the species Haploclastus devamatha Prasanth & Jose, 2014 is indistinguishable from Thrigmopoeus psychedelicus Sanap & Mirza, 2014, the latter is herein considered junior synonym of the former. Occurrence of polychromatism in H. devamatha is noted, and two distinct colour morphs of the species are recognised, a pink form and a blue form. The natural history and conservation of the species are discussed and its known distribution is updated.
ABSTRACT
The South Asian millipede genus Chondromorpha Silvestri, 1897 is diagnosed and its relationship with Parchondromorpha Jeekel, 1980 is established. The species C. atopus (Chamberlin, 1920) and C. indus (Chamberlin, 1920), as well as the subspecies C. kelaarti kelaarti (Humbert, 1865), C. kelaarti longipes (Verhoeff, 1936) and C. kelaarti valparaiensis (Carl, 1932) are recognised as junior synonyms of C. kelaarti (Humbert, 1865), thereby reducing the total number of Chondromorpha spp. in India to four: C. kaimura Turk, 1947, C. kelaarti, C. mammifera Attems, 1936 and C. severini Silvestri, 1897 (the type-species). Two species, C. kelaarti and C. mammifera, are redescribed and illustrated in detail. All four Indian Chondromorpha spp. are keyed, and the known distribution records of C. kelaarti and C. mammifera are mapped.

In order to unravel the synonymy of Rhinogobius Gill 1859, a neotype for Rhinogobius carpenteri Seale 1910, type species of its oldest synonym, Tukugobius Herre 1927, is designated and described based on topotypic material. The genus Tukugobius is removed from the synonymy of Rhinogobius from which it is distinct in having a longitudinal cephalic lateralis system, a naked pectoral-fin base, the first dorsal fin supported by 7 pterygiophores, and the first pterygiophore of the second dorsal fin inserted in interneural space 9. Its type species further differs from other species of Philippine Tukugobius by the presence of a median naked strip along the belly.

Holo- and paratypes of the root-knot nematodes Meloidogyne mayaguensis Rammah & Hirschmann, 1988 and Meloidogyne enterolobii Yang & Eisenback, 1983 were morphometrically and morphologically compared. All observed female, male and second-stage juvenile morphometrical and morphological characters are identical for the two studied species. Additionally, contradictions between the original species descriptions were unravelled.The present study of holo- and paratypes confirms the taxonomical status of Meloidogyne mayaguensis as a junior synonym for Meloidogyne enterolobii.
ABSTRACT
The genus Achrysocharoides Girault is here reported for the first time from tropical America. Included are ten species, eight newly described: Achrysocharoides asperulus, Achrysocharoides callisetosus, Achrysocharoides cuspidatus, Achrysocharoides foveatus, Achrysocharoides infuscus, Achrysocharoides mediocarinatus, Achrysocharoides purpureus, Achrysocharoides sulcatus, and two already known: Achrysocharoides ecuadorensis (Hansson) and Achrysocharoides gliricidiae (Hansson & Cave). All species are included in an identification key, diagnosed, described and illustrated. Only one of the species, Achrysocharoides gliricidiae, has a host record, an endoparasitoid in a leafmining Gracillariidae (Lepidoptera) on Gliricidia sepium (Fabaceae), thus conforming to the biology of extralimital Achrysocharoides species. The genus Kratoysma Boucek is here established as a junior synonym of Achrysocharoides, and the following species previously in Kratoysma are here recombined to Achrysocharoides: Kratoysma citri Boucek, Kratoysma ecuadorensis Hansson, Kratoysma gliricidiae Hansson & Cave, Kratoysma longifacies Hansson, Kratoysma nepalensis Hansson, Derostenus usticrus Erdös.
ABSTRACT
A proposal to synonymize the freshwater crab species Hypolobocera solimani and Hypolobocera triangula from Colombia. It is proposed that Hypolobocera solimani and H. triangula be considered junior synonyms of H. alata and H. rotundilobata, respectively. We state that the following morphological differences represent natural variations within the population: a) first male gonopod, third maxilliped and larger cheliped between H. alata and H. solimani, and b) the differences of the first male gonopod between H. rotundilobata and H. triangula. Rev. Biol. Trop. 56 (3): 987-994. Epub 2008 September 30.
Se propone considerar las especies H. solimani e H. triangula como sinónimos de H. alata e H. rotundilobata, respectivamente. Se afirma que las diferencias morfológicas a) del primer gonopodo, del tercer maxilipedo y de la quela mayor entre H. alata e H. solimani y b) las diferencias del primer gonopodo entre H. rotundilobata e H. triangula, no son significativas y se originan en variaciones naturales propias de las poblaciones.
