Five new species of Triotemnus (Coleoptera, Curculionidae, Scolytinae) from Morocco and Yemen

Fivenew species of the genus Triotemnus from Morocco and Yemen are described. Triotemnus is a new genus of Scolytinae for the Yemen region. External morphology of the new species and all morphologically related species of the genus were studied. While the new species from Morocco are morphologically similar to the known species from the corresponding region, all three newly described species from Yemen, mainly two of them living in Socotra, are morphologically very different from all other known species of the genus. Geographical distribution and the probability of endemicity are discussed.     

A new species of Kanahia (Asclepidiaceae) with a reconsideration of the genus

A new species, K. carlsbergiana , is described in what is currently considered a monotypic genus. The new species is only known from permanent streams in the Arssi and Bale regions of S Ethiopia. The delimitation and position of the genus is reconsidered in light of the additional information provided by the new species. The distinctiveness of the genus is reconfirmed whilst no new clues to possible relationships with other genera were observed. The taxonomy of the other species, K. laniflora (Forssk.) R. Br., is also briefly reconsidered.

A new genus of soft coral of the family Alcyoniidae (Cnidaria, Octocorallia) with re-description of a new combination and description of a new species

A new genus, Aldersladum (family Alcyoniidae), is established to accommodate a previously described species, Efflatounaria sodwanae Benayahu, 1993 (family Xeniidae) from Sodwana Bay, South Africa that was wrongly assigned to the latter genus. This species is redescribed and a second new species, Aldersladum jengi from Penghu Is., Taiwan, is described. The diagnostic features of the new genus include the presence of only figure-eight shaped platelets in all parts of the colony, thus differentiating it from all known genera of the Alcyoniidae. Based on examination of additional material from other localities, the zoogeographical distribution of the genus is confirmed to include the coral reefs of South Africa, Kenya, Gulf of Oman, Taiwan and Japan. Phylogenetic analyses of two mitochondrial genes strongly support its placement in the family Alcyoniidae.     

Crassophyllum thessalonicae sp.n. (Octocorallia, Pennatulacea), from the Aegean Sea

A new pennatulacean species, Crassophyllum thessalonicae sp.n. is described from the Mediterranean (North Aegean Sea). This is the first record of a Crassophyllum Tixier-Duri vault, 1961 species from the Mediterranean Sea. The differences between the new species and C. cristatum Tixier-Durivault, 1961, the other known species of the genus, are discussed, and the genus Crassophyllum is critically compared with the other two related genera Pteroeides Herklots, 1858 and Sarcoptilus Gray, 1848.     

On a new trematode, Prohemistomum azimi n. sp. (Trematoda: Cyathocotylidae) from the Egyptian slit-faced bat

Prohemistomum azimi n. sp. is described from one out of four Egyptian slit-faced bats, Nycteris thebaica Geffroy, 1910 captured from Giza, Egypt. The new species is compared with other related species of the genus and its specific diagnosis is outlined. The new species is the first record of the genus Prohemistomum Odhner, 1913 from Chiroptera.     

A new mermithid nematode in imagos of Cladopelma collator (Townes) (Diptera: Chironomidae) eclosing from waterways in northern Minnesota

Octomyomermis connellyi n. sp. (Nematoda: Mermithidae) is described from the hemocoel of male and female imagos of Cladopelma collator (Townes) eclosing from Lake Ozawindib and from Gulsvig Landing in the upper Mississippi River in northern Minnesota. The species is distinguished from the other species in the genus. Included is a list of the other 9 adequately described members of the genus Octomyomermis that have been reported from the United States (California and Minnesota), Argentina, Russia, and Zambia. Bionomics and anomalies of the new species are addressed.     

Four new species of the myrmecophile Diplocotes Westwood (Coleoptera: Ptinidae) from Queensland and South Australia

Abstract  Four new species of the Australian ptinid genus Diplocotes are described. Two of these species are from the dry tropical and subtropical areas of northern and central Queensland, while the other two are from the arid areas of South Australia. While the four new species described here have not been observed with ants in the field, the species of this genus are known to be myrmecophilous, and similar interactions may occur between the new species and their host ants. Additionally, many characters are shared with other unrelated myrmecophilous species, and may be convergent adaptations to the ant-associated lifestyle.

A phylogenetic study of Lepidapedoides Yamaguti, 1970 (Digenea) with a key and descriptions of two new species from Western Australia

Two new species of the genus Lepidapedoides are described from the aulopodid teleost Aulopus purpurissatus from south-western Australia. Both are distinguished from other Lepidapedoides spp. by their pedunculate ventral sucker. Lepidapedoides pistoris n. sp. and L. elongatrium n. sp. are distinguished by the possession of a narrow, elongate form, a long ventral sucker to ovary distance, the vitellarium reaching only to the posterior level of the cirrus-sac, the cirrus-sac length and the deep genital atrium with the metraterm entering distally to its base in L. elongatrium. A key to species of the genus is given. A character matrix is included for the genus. Poorly resolved phylogenetic trees indicate two main lineages in the genus. The two new species described here are resolved as sister taxa. The new combination Lepidapedoides freitasi (Kohn &; Fernandes, 1970) is formed for Acanthocolpoides freitasi.
