An attempt was made to test if Lourinia armata (Claus, 1866)—as it is currently diagnosed—represents a species complex. Detailed examination and comparisons of several specimens collected from different localities suggest that L. armata indeed represents a complex of four closely related morphospecies that can be differentiated from one another by only detailed observations. One of the four species is identified as Lourinia aff. armata and the other three species are described as new to science and named as Lourinia wellsi sp. nov., L. gocmeni sp. nov., and L. aldabraensis sp. nov. Detailed review of previous species records indicates that the genus Lourinia Wilson, 1924 is distributed worldwide. Ceyloniella nicobarica Sewell, 1940, originally described from Nicobar Island and previously considered a junior subjective synonym of L. armata is reinstated as Lourinia nicobarica (Sewell, 1940) comb. nov. on the basis of the unique paddle-shaped caudal ramus seta V. It is postulated that almost all of these records are unreliable in terms of representing true Lourinia aff. armata described herein. On the other hand, the comparative evaluation of the illustrations and descriptions in the published literature indicates the presence of several new species waiting to be discovered in the genus Lourinia.                 It has been determined that, according to updated modern keys, the recent inclusion of the monotypic genus Archeolourinia Corgosinho & Schizas, 2013 in the Louriniidae is not justified since Archeolourinia shermani Corgosinho & Schizas, 2013 does not belong to this family but should be assigned to the Canthocamptidae. On the other hand, it has been argued that the exact phylogenetic position of the Louriniidae still remains problematic since none of the diagnostic characters supports the monophyly of the family within the Oligoarthra. It has also been argued that the close relationship between Louriniidae and Canthocamptidae is supported since both families share the homologous sexual dimorphism (apophysis) on P3 endopod. The most important characteristic that can possibly be used to define Louriniidae is the reduction of maxilliped.

The genusCleafrom SE Asia is from one of only two unrelated families among the megadiverse predatory marine Neogastropoda to have successfully conquered continental waters. While little is known about their anatomy, life history and ecology, interest has grown exponentially in recent years owing to their increasing popularity as aquarium pets. However, the systematic affinities of the genus and the validity of the included species have not been robustly explored. Differences in shell, operculum and radula characters support separation ofCleaas presently defined into two distinct genera:Clea, for the type speciesClea nigricansand its allies, andAnentomeforClea helenaand allies. A five-gene mitochondrial (COI, 16S, 12S) and nuclear (H3, 28S) gene dataset confirms the placement ofAnentomeas a somewhat isolated offshoot of the family Nassariidae and sister to the estuarineNassodonta. Anatomical data corroborate this grouping and, in conjunction with their phylogenetic placement, support their recognition as a new subfamily, the Anentominae. The assassin snailAnentome helena, a popular import through the aquarium trade so named for their voracious appetite for other snails, is found to comprise a complex of at least four species. None of these likely represents trueAnentome helenadescribed from Java, including a specimen purchased through the aquarium trade under this name in the US and one that was recently found introduced in Singapore, both of which were supported as conspecific with a species from Thailand. The introduction ofAnentome“helena” through the aquarium trade constitutes a significant threat to native aquatic snail faunas which are often already highly imperiled. Comprehensive systematic revision of this previously unrecognized species complex is urgently needed to facilitate communication and manage this emerging threat.

The single and endemic species of Eupterote Hübner recorded from Australia is shown not to possess the male genitalia typical of this genus, nor of any other genus of Eupterotidae, and it is consequently placed in a new genus, Ebbepterote Oberprieler, Nässig & Edwards, as E. expansa (T. P. Lucas, 1891), comb. nov. Its genitalia are compared with those of many Asian and African genera of Eupterotidae, resulting in a revised classification and redefinition of the major eupterotid lineages. Five groups are defined: a probably paraphyletic 'basal' Ganisa-group and likely monophyletic subfamilies Janinae (including Tissanga Aurivillius and Hibrildes Druce), Striphnopteryginae, Eupterotinae and Panacelinae. Ebbepterote and the New Guinean 'Eupterote' styx Bethune-Baker species-complex are included in Striphnopteryginae, which is otherwise restricted to Africa. Cotana Walker is reassigned to Eupterotinae from Panacelinae and Sphingognatha Felder is resurrected from synonymy with Eupterote. The genitalia of Ebbepterote and several other critical genera are illustrated, demonstrating that the shape of the uncus does not constitute a suitable synapomorphy for defining the Eupterotidae as a monophyletic group. Another alleged eupterotid synapomorphy, the presence of a row of midventral spurs on the apical tarsal segment of the hindleg of the female, is shown to occur only sporadically in the family but also outside of it, in the lemoniid–brahmaeid–sphingid clade of Bombycoidea. As a result, the monophyly of the Eupterotidae currently rests only on a single, cryptic character of the mesoscutum of the imago and is in urgent need of substantiation.

The genus Monochoria is represented in Sri Lanka by only two species, M. hastata and M. vaginalis. Of the two species M. vaginalis exhibits a high morphological diversity. A morphometric analysis was performed on the Sri Lankan members of the genus Monochoria to evaluate the morphological diversity exhibited by comparing 34 vegetative, anatomical and reproductive characters. Both cluster and principal coordinate analyses resulted in four clusters of which one corresponded to M. hastata, while M. vaginalis was divided into three phenetic groups indicating that the Sri Lankan M. vaginalis is a species complex involving more than one taxon. The length ratio of the lower spathe petiole to inflorescence stalk was identified as an informative character in delimiting the phenetic groups, a character that has not been considered before. Further, the occurrence of sub-palisade cavities that are filled with a red colored liquid in the leaves of two phenetic groups was a novel character for the genus as well as the family Pontederiaceae.Keywords: Monochoria vaginalis; Morphological data; Sub-palisade cavities; Principal coordinate anaysis.Bangladesh J.

Background: Thesium L. is the largest genus in the family Santalaceae (sandalwood family). The last taxonomic revision of the southern African species dates back to 1925. An urgent revision of the genus is required as indicated in a recent national biosystematics research strategy for South Africa.Objectives: To revise the Thesium confine species complex (Thesium durum, T. confine and Thesium spartioides) and to update the typification, nomenclature, descriptions and distribution ranges.Method: Morphological characters were studied using own field collections as well as herbarium specimens from K, NU, PRE and PRU and images on Global Plants (JSTOR). Distribution ranges of the studied species were updated.Results: An examination of morphological characters revealed great similarity between T. spartioides and T. confine. Both species have an herbaceous habit, decumbent growth form, terminal (or less frequently axillary) inflorescences and a sympatric northern distribution in South Africa. Thesium durum differs from T. spartioides and T. confine in having a shrubby habit, erect growth form and axillary inflorescences and occurs in the southern part of South Africa.Conclusion: Thesium spartioides is synonymised under T. confine, and T. durum is retained as a separate species.

High Diversity

Within the family Archaeobalanidae, the sponge-inhabiting barnacles include species from the subfamilies Acastinae and Bryozobiinae as well as from the genus Membranobalanus in the subfamily Archaeobalaninae. Members of these groups are obligatory symbionts of poriferans, but the Acastinae can also be found in association with alcyonaceans and antipatharians. Acasta sulcata Lamarck, 1818, is one of the most widely reported sponge-inhabiting barnacle species, with numerous records across the Indo-West Pacific region revealing significant morphological variation. A combined morphological and molecular approach has revealed high diversity in recent collections of sponge-inhabiting barnacles in Taiwan and Australia, and four new species, namely Acasta aspera sp. nov., Acasta huangi sp. nov., Acasta radenta sp. nov., and Acasta undulaterga sp. nov., have been described here. All four species are morphologically close to A. sulcata, and the morphological similarity between these proposed species has led to the proposal of a “sulcata species complex.”

AbstractThe species complex and infestations of aphids on plum (Prunus persica) and cherry plum (Prunus cerasifera) in Bulgaria were investigated during the period 2013–2018. Nine species from the family Aphididae were found: Brachycaudus helichrysi Kaltenbach (leaf-curling plum aphid), Hyalopterus pruni Geoffroy (mealy plum aphid), Phorodon humuli Schrank (hop aphid), Brachycaudus prunicola Kaltenbach (brown plum aphid), Brachycaudus cardui Linnaeus (thistle aphid), Brachycaudus persicae Passerini (black peach aphid), Rhopalosiphum nymphaeae Linnaeus (waterlily aphid), Aphis spiraecola Patch (spiraea aphid) and Pterochloroides persicae Cholodkovsky (peach trunk aphid). The dominant species on plum are Hyalopterus pruni and Brachycaudus helichrysi. The first species is more widespread and of significantly higher density. The dominant species on cherry plum are Phorodon humuli and B. helichrysi. The species Brachycaudus prunicola is widespread both on plum and cherry plum in Bulgaria. It was found only on twigs, and therefore cannot be considered as a dangerous pest on fruit-bearing plum trees. The other species, some of them described as dangerous pests on plum, are today fairly rare and occur in low density, thus posing no danger to orchards.

History Of

The genus Macrobrachium Bate, 1868 is one of the best examples of widespread crustacean genera distributed globally throughout tropical and subtropical waters. Previous investigators have noted the systematic complexity of the group, and have suggested rearrangements within the family Palaemonidae. Our phylogenetic analysis of new mitochondrial DNA sequences of 58 species of Macrobrachium distributed mainly in America support the hypothesis of monophyly of this genus, if Cryphiops Dana, 1852 is accepted as a generic synonym. We concluded that the independent evolution of different types of life cycle (abbreviated larval development – ALD and extended larval development – ELD) must have occurred more than once in the history of the group. Similarly, we also concluded that the current type species of the genus, Macrobrachium americanum Bate, 1868, should not be considered valid, as previously proposed. The synonymy of two members of the ‘olfersi’ species complex (M. birai Lobão, Melo & Fernandes, 1986 and M. holthuisi Genofre & Lobão, 1978) with M. olfersi (Wiegmann, 1836) was confirmed. Similar results were found in comparing M. petronioi Melo, Lobão & Fernandes, 1986 and M. potiuna (Müller, 1880), in which the genetic divergence placed M. petronioi within the level of intraspecific variation of M. potiuna. The taxonomic status of the genus Cryphiops, as well as theories on the origin of Macrobrachium, is also called into question.

Aquatic insects in the family Naucoridae are commonly known as creeping water bugs or saucer bugs. The New World genus Ambrysus (Heteroptera: Naucoridae) includes two subgenera in Mexico: Ambrysus (Syncollus) La Rivers and Ambrysus (Ambrysus) Stal. Syncollus includes nine species with mostly Neotropical distributions. The subgenus Syncollus was reviewed and the status of the Mexican fauna was evaluated. Six species of this group are present in Mexico; three of them were described as new in this study. In the subgenus Ambrysus, the A. hybridus Montandon species complex was revised and includes nine species distributed in North America. One of the Mexican species was resurrected as a valid species and two other were considered the same as a third species that was not well known prior to this work. The Ambrysus guttatipennis Stal species complex also was revised and includes eleven species distributed in North America. Six species of this group from Mexico were described as new.
