<em>Anthaxia</em> (<em>Haplanthaxia</em>) <em>flaviae</em> n. sp. from the Aeolian Islands (Italy, Sicily) belonging to the <em>A</em>. (<em>H</em>.) <em>olympica</em> Kiesenwetter, 1880 species-group is described, illustrated and compared with <em>A</em>. (<em>H</em>.) <em>scutellaris</em> (Gené, 1839), the most closely related species. From this latter, the new species differs mainly for size and body shape, colour pattern of elytrae, shape of antennomera, margin of anterior tibiae and shape of aedeagus. Some zoogeographical considerations concerning the insular distribution of this endemic taxon are briefly discussed.

AbstractThree new species of snapping shrimps of the genusAlpheusare described from the Persian Gulf. These belong to theAlpheus edwardsiispecies-group, which is mainly characterized by unarmed orbital hoods and the presence of dorsal and ventral notches on the palm of the major chela.Alphus ankerisp. nov. shows a close affinity toA. pacificusDana, 1852 andA. heronicusBanner & Banner, 1982 bearing no balaeniceps crests in both sexes on the dactylus of the minor chela, and the merus of the major chela of both sexes are unarmed. This species differs from the closely related species by the absence of an overhanging proximal shoulder in the major chela. The other rock crevice inhabiting species,A. mohammadpourisp. nov. is diagnosed by exhibiting sexual dimorphism in its balaeniceps crests and the armed merus of the major chela. These two characters are similar to those recorded for three sandy/rubble dwelling species:A. inopinatusHolthuis & Gottlieb, 1958,A. lobidensDe Haan, 1849 andA. australiensisBanner & Banner, 1982. This new species is distinguishable from these latter species by the shape of the minor chela and colour pattern. A coral inhabiting speciesA. abumusasp. nov. appears to be closely related toA. maindroniCoutière, 1898, showing an armed merus of the major chela and the absence of spine-like seta on the ischia of the third legs. This last new species is easily discriminated fromA. maindroniby longer antennular segments, a markedly concave frontal margin between the rostrum and orbital hood, and a different colour pattern.

Dugesia Gonocephala Group

Dugesia gonocephala is a species group, comprising numerous closely related species, which differ from each other in morphological and karyological aspects. In this paper known and presently described species, of the group from the eastern Mediterranean region, are reviewed. Hitherto the triclads of this region have been poorly known in comparison with their western counterparts. Yet there is a wealth of species in the area. Six well-delimited new species of the Dugesia gonocephala group are described and one further species is rescued from synonymy. The wealth of material available has also made possible an assessment of the taxonomic validity of many characters usually considered to be of importance within this difficult group.

The species of the Eumerus tricolor species group in Iran are reviewed. Six species new to science are described from Iran, i.e., Eumerus atricolorus Gilasian &#38; van Steenis sp. nov., E. brevipilosus Gilasian &#38; van Steenis sp. nov., E. chekabicus Gilasian &#38; van Steenis sp. nov., E. ovoformus Gilasian &#38; van Steenis sp. nov., E. pilosipedes Gilasian &#38; van Steenis sp. nov. and E. vallicolus Gilasian &#38; van Steenis sp. nov. Three species, E. hissaricus Stackelberg, 1949, E. longitarsis Peck, 1979 and E. richteri Stackelberg, 1960, are newly recorded from Iran. Photographs of the species as well as illustrations of the male genitalia of the new species and closely related species are provided. An identification key to the males of the Iranian Eumerus tricolor species group is presented. A row of long posterodorsal setae on the wing vein costa basally is presented and argued as a new diagnostic morphological character for the entire Eumerus tricolor species group.

Bush Cricket

A new interesting species of the genus Isophya, I. horon sp. n., is described from Northeastern part of Turkey. The new species can clearly be distinguished from the closely related species by the calling song of male, and morphology. Morphologically, the shapes of the pronotum, tegmina, male cerci and ovipositor are distrinctive. The morphology, song structure and distribution clearly indicate that this new species is a member of the I. zernovi species-group. Additionally, some preliminary data on the male calling songs of closely related species (I. zernovi, I. karadenizensis and I. autumnalis) are also given. In addition, the preliminary data related to spermatophore characteristics (spermatophylax and ampulla weights) and sperm number of the new species are provided.

Osteological Characters

An extinct ictalurid catfish, Ictalurus spodius n. sp., is described from the Pleistocene of Central Mexico. It shares derived osteological characters with the subgenus Ictalurus and the I. punctatus species group. The new species is known from middle Pleistocene fluvial and lacustrine sediments and was abundant until near the end of the Pleistocene when it was replaced by a closely related species, I. dugesi. The latter is known from late and post-Pleistocene lake-bottom deposits and is widespread in Central Mexico today.

Herein I describe Isophya sonora sp. nov. a new bush-cricket species from Trabzon, Northeastern part of Turkey (Black Sea Region). The species is characterized by the shape of the markedly convergent fastigium, distinctly broadened pronotum at metazona, elongate tegmina and large mirror area of left tegmen in the male. The bioacoustic characteristics, and the shape and number of the teeth of stridulatory organs are also different compared to closely related species. The new species is clearly a member of I. zernovi species-group allied with I. bivittata. Both the bioacoustics, and the morphological data, demonstrate the relationships between species of the I. zernovi species-group are as follows: (I. bicarinata + (I. zernovi + I. horon)) + (I. sonora sp. n. + I. bivittata?))) + (I. karadenizensis + I. autumnalis)))).

A New Species

We describe Lepidotrigona satun Attasopa and Bänziger new species from southern Thailand based upon associated males and females (workers). The new species is a member of the L. ventralis species group, which is otherwise represented in Thailand only by L. flavibasis and L. doipaensis. We also describe the males of the latter two species, associated with nests from close to their type localities in northern Thailand. Lepidotrigona doipaensis Schwarz and L. flavibasis (Cockerell) had previously often been misidentified as L. ventralis (Smith), a species confirmed only from Borneo. Based upon differences in male morphology, especially of the metasomal sterna, we conclude that the male described from Vietnam by Sakagami (1975) as belonging to L. flavibasis represents an undescribed species. Our findings support previous taxonomic studies that highlight the importance of including males in the differentiation of closely related species of meliponines and their association with workers. The three species whose males we describe have asymmetric penis valves with the asymmetry differentially developed among the three. We compare this genitalic asymmetry with that known from a different apid genus, Tarsalia.

A New Species

<em>Meligethes</em> (<em>Odontogethes</em>) <em>inexpectatus</em> sp. n. is described from China, Sichuan Province. The new species is based on a female specimen previously incorrectly referred to as <em>Meligethes</em> <em>scrobescens</em> Chen, Lin, Huang &amp; Yang, 2015, which was recently described from a series of male specimens collected in the same area. Both species belong to the taxonomically difficult species-group related to M. chinensis Kirejtshuk, 1979, including a dozen closely related species distributed throughout Nepal and SW and Central China. The true female of <em>Meligethes scrobescens</em> is also described, based on recently collected material from China (Hubei and Chongqing), including a series of male and female specimens. Diagnostic characters distinguishing the new species from all other known members of the<em> M. chinensis</em> species-group and species-complex are discussed, and their overall range distribution are depicted. Additional data on geographic distribution and larval ecology of some of the closely related species are also reported.
