The New World family Syringogastridae (Diptera, Acalyptratae) with the single genus Syringogaster is revised. Eleven new extant species are described in four newly recognized species groups to give a total of 20 extant species (S. brachypecta, S. apiculata and S. tenuipes in the rufa-group; S. atricalyx, S. figurata, S. plesioterga, and S. dactylopleura in the figurata-group; and S. nigrithorax, S. brunneina, S. sharkeyi and S. palenque in the brunnea-group; Marshall & Buck are the authors of all extant new species). The craigi-group includes two new fossil species, S. miocenecus Grimaldi and S. craigi Grimaldi, each described on the basis of a unique Miocene (ca. 17 myo) amber specimen from the Dominican Republic. Morphological and molecular characters are used to estimate phylogenetic relationships among species of Syringogastridae, and between Syringogastridae and related diopsids. The fossil species appear to form the sister group to the Central and South American figurata group, and reveal Antillean extinction of the family from earlier in the Tertiary.

Single Genus

The family Corethrellidae, called frog-biting midges, with the single genus Corethrella Coquillett, 1902, is a small group of dipterans including 107 extant species (Borkent, 2017). Females of most species are haematophagous and feed on males of frogs and toads locating them by their calls (Borkent, 2008). Extant frog-biting midges have a pantropical distribution, absent in Europe, north Africa, middle and northern Asia (Giłka & Szadziewski, 2009). The genus during its phylogenetic history dated back to Lower Cretaceous (125–129 Ma) had a broader geographical distribution, and during Eocene was present in Europe. Till now nine fossil species have been described from Lower Cretaceous Lebanese amber (1), mid-Cretaceous Burmese amber (1), Eocene Baltic amber (5) and Miocene Dominican amber (2) (a complete annotated list is provided below).

A New Species

A new species, Nothochrysaehrenbergisp. nov., is described from Chile; it is the first species of Nothochrysa to be reported from the Southern Hemisphere and only the second from the New World. The genus now contains six extant species as well as two species known from late Oligocene and Miocene fossils. An updated catalog of the valid Nothochrysa species is presented, and three nomina dubia are discussed. The inclusion of the new species in Nothochrysa is well supported by morphological features. However, it and other species currently in the genus also share significant features with Archaeochrysa, an older genus of Nothochrysinae which is known only from the Eocene (Ypresian) to the late Oligocene. It therefore appears that N.ehrenbergi is among the least derived Nothochrysa species, and that the separation of Archaeochrysa from Nothochrysa is open to question and further examination.

A New Species

Masona popeye Quicke & Chaul sp. n. is described from Brazil, and differentiated from other species of the genus. Described extant species of Masona are known from Australia and south eastern U.S.A. (Georgia and Florida including the Key Islands). Two undescribed species are known from Tanzania and Cambodia. The new species is therefore the first representative of the subfamily Masoninae van Achterberg from South America, demonstrating the completely cosmopolitan distribution of this very poorly known group. The new species most closely resembles a fossil species, M. pyriceps van Achterberg, 2001, from Dominican amber with which it shares the plesiomorphic presence of a scutellum.

American Clade

The generic placement of New World pholcids assigned to the genus Leptopholcus Simon, 1893 has long been questioned and recent molecular data have shown that Caribbean (Hispaniolan) representatives are more closely related to the Old World genus Micropholcus Deeleman-Reinhold & Prinsen, 1987 than to ‘true’ African Leptopholcus (Dimitrov, Astrin and Huber 2013, Cladistics 29: 132–146). Here we provide new molecular (16S, 18S, 28S, COI, H3, WNT1) and morphological data about Caribbean (Cuban, Puerto Rican) and South American (Brazilian) representatives, supporting the sister-group relationship with Micropholcus and suggesting a monophyletic New World clade that in turn consists of a Caribbean and a South American clade. The ten New World species previously assigned to Leptopholcus are thus transferred to Micropholcus for which an emended diagnosis is provided: M. baoruco (Huber, 2006), comb. nov.; M. brazlandia (Huber, Pérez & Baptista, 2005), comb. nov.; M. dalei (Petrunkevitch, 1929), comb. nov.; M. delicatulus (Franganillo, 1930), comb. nov.; M. evaluna (Huber, Pérez & Baptista, 2005), comb. nov.; M. hispaniola (Huber, 2000), comb. nov.; M. jamaica (Huber, 2000), comb. nov.; M. kiskeya (Huber & Wunderlich, 2006), comb. nov.; M. pataxo (Huber, Pérez & Baptista, 2005), comb. nov.; M. toma (Huber, 2006), comb. nov. Four Brazilian species are newly described: M. piaui, sp. nov.; M. piracuruca, sp. nov.; M. crato, sp. nov.; M. ubajara, sp. nov. Natural history data are provided for M. piaui and M. ubajara.

AbstractSeven new species of Milichiella are described from Dominican amber: M. archaia n. sp., M. dolichosurstyla n. sp., M. dominicana n. sp., M. hennigi n. sp., M. margaretae n. sp., M. quadrisetosa n. sp., and M. theodori n. sp. These species represent the first record of the sub-family Milichiinae in amber and the first descriptions of the family in Dominican amber. The fossil species differ from extant species only in species-level details except M. archaia, which probably belongs to the stemline of Milichiella + Ulia.

The oribatid mite genus Caleremaeus (Caleremaeidae) is widely distributed in the northern hemisphere but has been represented by only three extant and one fossil species. We redescribe the North American C. retractus (Banks, 1947) based on adults and nymphs; it is distinguishable from the European type species, C. monilipes (Michael, 1882) by its smaller adult size and minor differences in cuticular structure, and by the elongated, tapered form of seta h1 in nymphs. Two new species are proposed: C. nasutus n. sp. from forest soil in Alabama is unique in having adults with a large anterior rostral lobe (juveniles unknown) bearing lamellar setae; the arboreal C. arboricolus n. sp. from eastern USA and Canada is unique among described extant species in having adults with femoral saccules, a transverse ridge bearing lamellar setae and relatively large notogastral setae, and juveniles with a bothridial seta similar to that of the adult. Based on all available data, Caleremaeus is redescribed and considered the sole genus in Caleremaeidae. The higher classification of the family is reviewed, and past placement in Ameroidea is rejected in favor of the monofamilial Caleremaeoidea.

First Time

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.

High Diversity

Pheidole comprises approximately 1,000 extant species distributed worldwide, being particularly diverse in the New World. In addition to its high diversity and ecological prevalence, the genus is also characterized by the predominantly intraspecific dimorphism, with major and minor workers. Currently, five fossil species are known, all of which are represented only by minor workers. A new species, †Pheidoleanticuasp. nov., is described from Dominican amber, based on a major worker. Additionally, the identity of the currently known fossil species in Pheidole is discussed and †P.cordata from Baltic amber is considered as incertae sedis, resulting in no Pheidole species currently recognized for Baltic amber

Two New Species

Leaves of three species belonging to the family Araucariaceae are described from two Eocene localities in Tasmania. Araucarioides gen. nov. is proposed to contain the fossil species. The erection of a new genus is necessary for two reasons. Two new species, A. linearis and A. sinuosa, are intermediate between Agathis and Araucaria and do not have the Florin rings which are the characteristic of extant species of Araucariaceae. The third new species, A. annulata, while clearly belonging to the Araucariaceae, is not well enough preserved to be assigned to an extant genus. These species confirm the presence of the subtropical/tropical Araucariaceae in Tasmania in the Eocene. The evolutionary position of the fossil species is uncertain at present.

The chelonian fauna of the Portezuelo Formation (Turonian-Coniacian), outcropping at Sierra del Portezuelo (Neuquén province, Argentina), is reported. Two new taxa of pleurodiran turtles are described. One of them is Prochelidella portezuelae new species, a short-necked chelid closely related to extinct species of the Lohan Cura (Albian), Candeleros (Cenomanian), and Bajo Barreal (Turonian) formations from northwestern and central Patagonia, and to the extant species of the genus Acanthochelys. The other is Portezueloemys patagonica new genus and species, a member of the epifamily Podocnemidoidea, and is considered the sister group of the family Podocnemididae. This discovery confirms the coexistence in northwestern Patagonia of a north gondwanan component (Pelomedusoides) and a south gondwanan element (Chelidae) during the Turonian-Coniacian.
