A New Species

Background and Aims: Cochemiea is a genus which currently comprises five species occurring in Mexico. It is morphologically characterized by cylindrical decumbent to prostrate stems and by a long red-scarlet zygomorphic perianth, presumably specialized for hummingbird pollination. As part ofthe ongoing taxonomic studies on the North Mexican flora, a population discovered by Thomas Linzen in 2012 in central Sinaloa (Mexico), previously identified as Mammillaria sp., actually refers to a Cochemiea species and cannot be ascribed to any of the known species of that genus. As a consequence,we here propose to describe this population as a a new species for science.Methods: The work is based on field surveys (autumn 2018 and spring 2019) in central Sinaloa, examination of herbarium specimens, and analysis of relevant literature. Its conservation status was assessed following the guidelines of the IUCN; AOO and EOO were calculated with the programGeoCAT.Key results: Cochemiea thomasii is described and illustrated from Sinaloa. The new species is morphologically similar to C. halei from which it differs by the hanging stems, the larger conical tubercles, less numerous and shorter central spines, and the ovoid fruits. A diagnostic key of the knownCochemiea species is included.Conclusions: Cochemiea thomasii is endemic to the state of Sinaloa where it occupies a small area. On the basis of the criteria B2a (geographic range) and C (small population) of IUCN, the new species can be assessed as Critically Endangered (CR) or Vulnerable (VU). Adopting the precautionary approach, Cochemiea thomasii is considered as Critically Endangered (CR).

African Genus

A new Tunisian species of Acantothereva Séguy is described, reducing several diagnostic characters for this North African genus to interspecific differences among the three included species. An expanded vertex and frons were formerly considered diagnostic for the genus, but the new species, A. oblata, sp. nov., has a vertex lower than the dorsal eye margin and a non-dilated ocellar tubercle. Previously recognized male genitalic characters, however, support the hypothesis that Acantothereva is a monophyletic group. The ability to recognize Acantothereva using external characters is marginally reduced with respect to therevine genera due to the inclusion of the new species, notably relative to Neotherevella Lyneborg. The apparent close phylogenetic relationship among Acantothereva, Acrosathe Irwin & Lyneborg, Irwiniella Lyneborg, and Neotherevella Lyneborg species are discussed herein, based on recent molecular phylogenetic analyses and the morphology of the Tunisian Acantothereva species. A key to the North African therevine genera is included; head and genitalia illustrations and a key to the three Acantothereva species are also presented.

Morphological Investigations

In the first months of 2013, a large group of plants of Centaurea belonging to the section Seridia, initially identified as a morphological variant of C. seridis subsp. sonchifolia, has been found during a naturalistic excursion in the Regional Natural Park of Punta Pizzo—Sant’Andrea Island. Morphological investigations, direct comparisons with species belonging to the same section, both through herbarium’s specimens and in vivo, and punctual bibliographical research indicate that this population belongs to a new species with some similarities with the Euro-Mediterranean C. seridis, C. polyacantha (a species with a distribution comprising the Iberian Peninsula and Morocco), or the North-African C. bimorpha and C. ferox, but is quite different by many characters illustrated in the present work. The new species here described is named C. akroteriensis Gennaio & Q.G. Manni.

The North African genus Afropachyiulus Schubart, 1960 is a poorly defined genus of the tribe Pachyiulini, the taxonomy of which is still obscure. In this paper we retrace the history of the genus Afropachyiulus, we describe A. mauriesi n. sp., from Algeria, and we redescribe the very similar A. comatus (Attems, 1899) from Tunisia based on type and new material.

A New Species

A new species of the genus Ocnogyna Graslin, [1837], O. mooseri sp. n. is described from north-eastern Libya. The female of the new species is fully winged but differs from all known species groups of Ocnogyna in a number of diagnostic features and is also externally reminiscent of Tajigyna gansoni Dubatolov, 1990 endemic to Tajikistan. The diagnostic comparison is made with the North African Ocnogyna advena (Fabricius, 1787) having externally similar males but brachypterous females and to the externally dissimilar Ocnogyna parasita (Hübner, 1790) species group having the most similar female genitalia structures.

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

A New Species

To date, only one species of Temnocephala is known from Chile, Temnocephala chilensis, and three from southern Argentina (Patagonia), namely T. chilensis, Temnocephala dionii, and Temnocephala mexicana. Here we describe a new species of Temnocephala and provide an updated description of T. chilensis based on material found on an anomuran crab (Aeglidae) from southern Chile. Additional hosts and localities are reported for both species in southern Argentina and Chile, and a diagnostic key for all species of Temnocephala hosted on Aegla and Parastacidae is included as well. In southern Chile, both T. chilensis and the new species were found on the crayfish Samastacus spinifrons and on the anomuran crabs Aegla abtao and Aegla alacalufi; in addition, the new species was found on Aegla manni, and T. chilensis on Aegla rostrata. In southern Argentina, T. chilensis and the new species were found on Aegla riolimayana and S. spinifrons. Based on their shared traits (morphology of the penial stylet, host preferences and geographic distribution), the temnocephalans hosted in Aegla are tentatively gathered into two clusters, the Chilensis and Axenos groups.

A new species of amphipod, Bathyporeia watkini sp. nov. from the Atlantic coasts of North Africa is described. This very characteristic species is abundant in some lagoons and estuaries near 28°N. New morphological information on B. elkaimi d’Udekem d’Acoz and Menioui, 2004 is given after specimens that were recently collected on the Atlantic coasts of southern Spain and South Portugal. The male of B. ledoyeri d’Udekem d’Acoz and Menioui, 2004 is described for the first time and new records of North African B. guilliamsoniana (Bate, 1857) and B. chevreuxi d'Udekem d'Acoz and Vader, 2005a are discussed.
