RESUMO
Suphisellus grossoi sp. n. is described from the Reserva Natural del Bosque de Mbaracayú, Canindeyú department, Paraguay. Diagnostic characters are described and illustrated in detail. New records are provided for S. flavolineatus (Régimbart, 1889) and S. grammicus (Sharp, 1882), which are also briefly diagnosed. Suphisellus melzeri Zimmermann, 1925 is proposed as a junior subjective synonym of S. flavolineatus (syn. n.), and lectotypes are designated for both taxa.

The Neotropical family Mesembrinellidae is revised. A total of 53 valid, extant species are included in the family, including 15 described as new and 38 redescribed based on study of type and non-type material and of the literature. A total of 18 primary types were examined. An additional ca. 2300 specimens, belonging to 47 species, were studied in detail, including dissection and photographic documentation of terminalia, with many females illustrated for the first time. Keys to subfamilies, genera, species-groups and species are provided. Type specimens of six species housed in South American institutions could not be obtained for study, i.e., M. bequaerti Séguy, 1925 and the five recently described species M. andina (Wolff et al., 2014), M. carvalhoi (Wolff et al., 2013b), M. cordillera (Wolff Ramos-Pastrana in Wolff et al., 2017), M. obscura (Wolff in Wolff et al., 2017) and Laneella patriciae (Wolff, 2013). We accept the synonymy, proposed by previous authors, of Eumesembrinella Townsend, 1931 with Mesembrinella Giglio-Tos, 1893. In addition, we synonymize the genera Albuquerquea Mello, 1967, Giovanella Bonatto in Bonatto Marinoni, 2005, Henriquella Bonatto in Bonatto Marinoni, 2005, Huascaromusca Townsend, 1918 and Thompsoniella Guimarães, 1977 with Mesembrinella Giglio-Tos, 1893, synn. nov., retaining three valid genera in the family: Laneella Mello, 1967, Mesembrinella and Souzalopesiella Guimarães, 1977. Laneella nigripes Guimarães, 1977 and Mesembrinella bellardiana Aldrich, 1922 are fixed as the type species of the genera Laneella Mello, 1967 and Mesembrinella Giglio-Tos, 1893, respectively, under Article 70.3 of the ICZN Code. We separate Mesembrinella into the following species-groups: M. latifrons (Mello, 1967), M. spicata Aldrich, 1925, M. bolivar (Bonatto in Bonatto Marinoni, 2005), M. aeneiventris (Wiedemann, 1830), M. bicolor (Fabricius, 1805), and M. anomala (Guimarães, 1977). The following 15 new species are described: Laneella fusconitida Whitworth, sp. nov. from Costa Rica, Ecuador and Venezuela, Laneella fuscosquamata Whitworth, sp. nov. from Guatemala and Mexico, Laneella purpurea Whitworth, sp. nov. from Costa Rica, Mesembrinella bullata Whitworth, sp. nov. from Bolivia, Mesembrinella chantryi Whitworth, sp. nov. from French Guiana and Brazil, Mesembrinella epandrioaurantia Whitworth, sp. nov. from Venezuela, Mesembrinella guaramacalensis Whitworth, sp. nov. from Venezuela, Mesembrinella longicercus Whitworth, sp. nov. from Bolivia, Mesembrinella mexicana Whitworth, sp. nov. from Mexico, Mesembrinella nigrocoerulea Whitworth, sp. nov. from Costa Rica, Ecuador and Venezuela, Mesembrinella serrata Whitworth, sp. nov. from Peru, Mesembrinella velasquezae Whitworth, sp. nov. from Venezuela, Mesembrinella violacea Whitworth, sp. nov. from Costa Rica, Mesembrinella woodorum Whitworth, sp. nov. from Ecuador, and Mesembrinella zurquiensis Whitworth, sp. nov. from Costa Rica. Mesembrinella abaca Hall, 1948 is proposed as a junior synonym of Mesembrinella socors (Walker, 1861), syn. nov. Lectotypes are designated for Dexia randa Walker, 1849 (now Mesembrinella) and Mesembrinella pictipennis Aldrich, 1922. We analyze the most extensive DNA-barcode dataset for Mesembrinellidae to date, encompassing the three genera considered valid and including 188 sequences (178 new) from 35 species, with data for 23 species provided for the first time. The topology of the resulting Neighbor-Joining tree is mostly congruent with morphology; however, some species show considerable genetic variation that is not reflected by morphology. Finally, we include a corrigendum to the recent Zootaxa paper on Nearctic Calliphora Robineau-Desvoidy (Diptera: Calliphoridae) by Tantawi et al.

Polyclads are a conspicuous group of marine invertebrates, the most charismatic members of the phylum Platyhelminthes. From Brazil, a total of 71 polyclad species were reported or described. Only three of them were recently described, five are recent records for the Brazilian coast, and 55 were described by Ernest and Eveline Marcus, who were by far the most productive workers. However, they quite often published in Portuguese or German, rather than English, and have not designated type material or specified material deposited in museum collections. Most of the polylcad material studied by the Marcus was found to be in the Swedish Museum of Natural History. Here we summarize the knowledge about Brazilian polyclad biodiversity, give information about deposited material in different museums for future reference, and designate type material for the species that did not have any. We examined 58 polyclad species reported from Brazil and designated type material and information available on type series of 52 species. Lectotypes (89 vouchers) were designated for 30 species and paralectotypes (73 specimens / 70 vouchers) were designated for 22 Brazilian species. Among the 261 type vouchers examined in this work, 22 species (77 vouchers) had material recognized as holotypes and 2 vouchers were recognized as paratypes. Of the total number of species reported from Brazil, 10 species remain without information about type material. In the present paper we also propose a new combination (Lurymare cynarium nov. comb.). Eleven species have their geographical distribution range broadened and 42 were photographed for the first time, five of those were photographed live as well. The number of Brazilian polyclad species is expected to rise when different regions and environments are surveyed.

An updated checklist of species of Ipomoea L. found in Cuba is presented with analysis of the different elements represented. I. alterniflora Griseb. is defined broadly to include I. obtusata Griseb. and I. excisa Urb. and its differences from the little-known I. cubensis (House) Urb. are discussed. I. calophylla C. Wright ex Griseb. is reinstated as the correct name for the species generally known as I. lacteola House. I. praecox C. Wright is recognised as a distinct species from I. argentifolia A. Rich. and images are provided to help distinguish the two species. I. flavopurpurea Urb. and I. dajabonensis Alain are shown to be conspecific with I. longeramosa Choisy, whose disjunct distribution is mapped and discussed. The little-known I. montecristina Hadac is described and illustrated and the cited collections show it to be locally common in the Guantánamo region. I. microdonta J. R. I. Wood & Scotland is described as new from Camagüey in central Cuba. Eight species endemic to Cuba collected by Ekman and described by Urban in 1924 - 25 are evaluated but only two, I. balioclada Urb. and I. erosa Urb., are deemed to warrant recognition as distinct endemic species. The origin and typification of I. horsfalliae Hook. are discussed and an epitype designated. Cultivated plants named I. horsfalliae occur in many tropical countries including Cuba but their extreme variation suggests hybrid origin. Four species from Jamaica, I. rubella House, I. lineolata Urb., I. carmesina Proctor and the Jamaican plant called I. horsfalliae are treated as synonyms of a variable I. lineolata, which is endemic to the island. I. saxicola Proctor is treated as var. saxicola J. R. I. Wood & Scotland of I. ternata Jacq. I. cyanantha Griseb. is treated as a synonym of I. lindenii M. Martens & Galeotti. Lectotypes are designated for I. cyanantha, I. lindenii, I. praecox, I. punctata C. Wright, I. geranioides Meisn. and I. grisebachii Urb.
