Ability To Regenerate

AbstractTwenty-eight pieces of amber from the Dominican Republic were studied. These pieces, 22–40 million years old, contain 29 cricket specimens as inclusions. Six new species in the Trigonidiidae: Trigonidiinae are described, one in the extant genus Anaxipha (A. dominica) and in three related new genera: Proanaxipha (P. latoca and P. bicolorata), Abanaxipha (A. longispina and A. incongrua), and Grossoxipha (G. yaque). One specimen is described in the Mogoplistidae: Mogoplistinae in the extant genus Ornebius (O. ambericus). The presence of these specimens in amber proves that utilization of the boreal habitat is of long standing. Disparity in the size of the hind legs of one specimen indicates that crickets may once have had the ability to regenerate lost limbs.

Bruchomyiinae from Burmese, Baltic, and Caribbean amber are revised. Five new species from Baltic, one from Caribbean and three from Burmese amber are described. Based on recently discovered specimens, additional details and corrections for previously described species are provided. Six species from Baltic amber were combined in Hoffeinsodes gen. nov. (Hoffeinsodes obtusa sp. nov., H. bifida sp. nov., H. cubicula sp. nov., H. longicauda sp. nov., H. reducta sp. nov. and H. hoffeinsi (Wagner 2006) comb. nov.), based on the fusion of gonocoxites and hypandrium, and a laterally expanded epandrium with posterolateral lobes. Genus Palaeosycorax Meunier, 1905 is re-validated, with Palaeosycorax inexpetatus (Wagner, 2012) comb. nov. included. Caribbean amber species Boreofairchildia dominicana sp. nov. and B. hennigianus (Schlüter, 1978) comb. nov. are congeneric with extant genus Boreofairchildia Wagner & Stuckenberg, 2016. Three new and two described species from Burmese amber are combined in Palaeoglaesum gen. nov. (Palaeoglaesum quadrispiculatum (Stebner et al., 2015) comb. nov., P. velteni (Wagner, 2012) comb. nov., P. muelleri sp. nov., P. bisulcum sp. nov., P. notandum sp. nov.), based on their small size relative to other Bruchomyiinae, and presence of a Y-shaped aedeagal sclerite. Keys to males of species in particular ambers are provided.

Orchid Seed

Aside from a variety of arthropod remains, Dominican amber also contains an assortment of leaves, flowers, and seeds. An orchid seed with a developing embryo in Dominican amber is described as Mycophoris elongatus gen. et sp. nov. Cells of the developing embryo were infected with a fungus that is described as Synaptomitus orchiphilus gen. et sp. nov. The fungus represents a Basidiomycota that was probably serving as an orchid mycorrhiza (OM), based on its morphology and the formation of pelotons inside infected embryo cells. The single piece of amber containing the fossil was obtained from a mine in the Dominican Republic and is at least 15–20 Ma.

AbstractHersiliidae Thorell is a family of conspicuously long-legged spiders, characterized by extremely elongate posterior lateral spinnerets. To date, it includes 148 species distributed within seven genera, of which Tama Simon is the only one recorded in the Neotropical Region. Of the 23 known Tama species, 18 are exclusively Neotropical. In order to enhance the scientific knowledge on the family and its members this study presents a cladistic analysis and a taxonomic revision of the Neotropical and Nearctic hersilids. The cladistic analysis places the Neotropical and Neartic species in two separate clades, none of which are closely related to the genus Tama. Based on this result, Tama mexicana (O.P.-Cambridge) and T. forcipata (F.O.P.-Cambridge) are transferred to Neotama and three new genera are proposed to include the remaining species: Ypypuera n. gen. to include T. crucifera Vellard and T. vittata (Simon); Iviraiva n. gen. to include T. pachyura Mello-Leitão and T. argentina Mello-Leitão; and Yabisi n. gen to include T. habanensis Franganillo. Based on the taxonomic revision, eight synonymies are proposed: Tama crulsi Mello-Leitão, Tama micrura Mello-Leitão and T. occidentalis Schenkel with Ypypuera crucifera (Vellard); T. brasiliensis Piza and T. karinae Carcavallo with I. pachyura (Mello-Leitão); T. catamarcaensis Carcavallo and T. longipes Carcavallo with I. argentina (Mello-Leitão); and T. guianensis Mello-Leitão with Neotama mexicana (O.P.-Cambridge); three names are placed as nomina dubia: Tama americana (Simon), T. albigastra Mello-Leitão and T. sasaimae Mello-Leitão and four new species are described: Neotama cunhabebe, from São Paulo, Brazil, Neotama obatala, from Bahia, Brazil, Ypypuera esquisita, from Quevedo, Ecuador, and Yabisi guaba, from Pedernales, Dominican Republic. The family Hersiliidae, the genus Neotama and all three new genera, as well as all Neotropical and Nearctic species are redescribed and diagnosed and a identification key is presented.

A New Species

A new species of scolebythine wasp (Chrysidoidea: Scolebythidae) is described and figured from a female beautifully preserved in Early Miocene amber from the Dominican Republic.  The specimen is the first fossil record of the extant genus <em>Clystopsenella</em> Kieffer, and is quite similar to the extant <em>Clystopsenella longiventris</em> Kieffer, a species that occurs widely from Brazil to Belize.  <strong><em>Clystopsenella mirabilis</em></strong> Engel, new species, is distinguished from <em>C. longiventris</em> on the basis of size; head, pronotal, and pterostigmal shape; and putative color differences.  The living and fossil diversity of the family is summarized and evolutionary patterns within the clade are discussed.

The Family

Nephila are large, conspicuous weavers of orb webs composed of golden silk, in tropical and subtropical regions. Nephilids have a sparse fossil record, the oldest described hitherto being Cretaraneus vilaltae from the Cretaceous of Spain. Five species from Neogene Dominican amber and one from the Eocene of Florissant, CO, USA, have been referred to the extant genus Nephila . Here, we report the largest known fossil spider, Nephila jurassica sp. nov., from Middle Jurassic (approx. 165 Ma) strata of Daohugou, Inner Mongolia, China. The new species extends the fossil record of the family by approximately 35 Ma and of the genus Nephila by approximately 130 Ma, making it the longest ranging spider genus known. Nephilidae originated somewhere on Pangaea, possibly the North China block, followed by dispersal almost worldwide before the break-up of the supercontinent later in the Mesozoic. The find suggests that the palaeoclimate was warm and humid at this time. This giant fossil orb-weaver provides evidence of predation on medium to large insects, well known from the Daohugou beds, and would have played an important role in the evolution of these insects.

Similar Combination

A strange moss is illustrated and described from Dominican amber (Miocene). It is densely triseriate foliate with ligulate lateral leaves which are strongly auriculate at base and small costate ventral leaves. A similar combination of characters is found in the Hypopterygiaceae, however, no extant species of this family matches the fossil. It is therefore described as Eophypopterygiopsis dominicensis J.-P. ,Frahm as new species in a new (possibly extinct) genus. In addition, the pantropical Pyrrhobryum spiniforme (Hedw.) Mitt. is recorded from Dominican amber for the first time, and Calyptothecium duplicatum (Schwaegr.) Broth. as well as a species of Homalia are reported.

The robber fly fauna of the 6 subfamilies Apocleinae, Asilinae, Laphrinae, Ommatiinae, Stenopogoninae, and Trigonomiminae of Hispaniola with special reference to the Dominican Republic is reviewed in light of new collections. This paper reports 6 genera (Cerotainia Schiner,   Eumecosoma Schiner, Holcocephala Jaennicke, Pilica Curran, Proctacanthella Bromley, and Rhopalogaster Macquart) new to the island, increasing the number to 20. Within the West Indies,   Eumecosoma, Holcocephala, Pilica, and Proctacanthella are only known from Hispaniola. Also, 33 species are reported, including 15 new species (Atomosia anacaona, A. ciguaya, A. jagua, A. jimagua, A. yurabia, Cerotainia sola, Eumecosoma caerulum, Holcocephala indigena, Ommatius geminus, O. laticrus, O. maculosus, O. praelongus, Proctacanthella taina, Plesiomma simile, and Rhopalogaster albidus), increasing the number to 62 species plus 2 species in Dominican amber. The male of O. cinnamomeus Scarbrough & females of Plesiomma inflatum and Proctacanthus darlingtoni Curran are reported for the first time. The Ommatius lucidatus species group is established with 8 extant and 2 fossil species. Plesiomma angustum (Macquart) and Atoniomyia mikii (Williston) are rediscovered and redescribed. Plesiomma lineata (Fabricius) is removed from the distribution list for Cuba and Jamaica and Neophoneus is removed from the list of West Indies asilids because of an error in identification. Neophoneus flavotibis Bigot tentatively diagnosed as belonging to the genus Efferia. Plesiomma macra Loew is removed from synonymy. Significant structures of most species are illustrated and keys to selected species are included. At least one species of Atoniomyia and Pilica remain undescribed from this survey. New distribution records for most species and a checklist of the Hispaniolan fauna are also included.

Dominican amber is the fossil resin famous for the best quality of inclusions, exploited in Dominican Republic from the deposits formed in the late Early Miocene, ca. 16 Ma. A new species, Polymera (Polymera) alexanderi sp. n. of the dipteran family Limoniidae is described from this amber. This new limonid belongs to the genus Polymera Wiedemann, 1820 with 63 extant species described mostly from South America. Only three fossil species are known so far from Dominican and Baltic amber.
