Abstract. Rhopalosomatidae are a family of aculeate wasps that are ectoparasitoids of crickets as larvae and are predominantly distributed pantropically. The published fossil record of the family is scarce. Here, we report three new fossil rhopalosomatid wasp specimens from Dominican and Mexican amber. Rhopalosoma hispaniola Lohrmann sp. nov. is described and documented from Dominican amber by two separate inclusions – one of each sex. An additional fossil female Rhopalosoma is described and documented from Mexican amber but is not named due to the insufficient preservation of the fossil. The new fossils, which are morphologically intermediate between Townes' isopus and poeyi species groups, do not only represent the first fossil records of an extant genus of this peculiar family but also the first records of the family in Dominican and Mexican amber.

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.

AbstractTwo new semiaquatic bugs of the families Mesoveliidae and Gerridae are described from the Middle Miocene Dominican amber, Mesovelia dominicana sp.n. and Miohebrus anderseni gen.n., sp.n. The former is the first fossil record of the extant genus Mesovelia and the second described fossil of the family Mesoveliidae (the first mesoveliid fossil record was from undescribed fossils in French Cretaceous amber). The latter is the second described fossil Hebridae.

Coleoptera Tenebrionidae

The fossil record of Tenebrionidae (excluding the Quartenary) is presented. In total, 122 fossil species, clearly belonging to the family, are known; some beetles were determined only to genus; 78 genera are listed in the fossil record, including 29 extinct genera. The great diversity of tenebrionids occurs in the Lower Cretaceous Lagerstätte of China (Yixian Formation), Middle Paleocene of France (Menat), Lower Eocene deposits of Germany (Geiseltal), Upper Eocene Baltic amber (Eastern Europe), Upper Eocene deposits of Florissant Formation (USA) and Miocene (Dominican amber). Tenebrionids of the following major lineages, including seven subfamilies, are currently known in the fossil record. These include the lagrioid branch (Lagriinae, Nilioninae), pimelioid branch (Pimeliinae), and tenebrioid branch (Alleculinae, Tenebrioninae, Diaperinae, Stenochiinae). The importance of the fossil record for evolutionary reconstructions and phylogenetic patterns is discussed. The oldest Jurassic and Early Cretaceous darkling beetles of the tenebrionoid branch consist of humid-adapted groups from the extant tribes Alleculini, Ctenopodiini (Alleculinae), and Alphitobiini (Tenebrioninae). Thus, paleontological evidence suggests that differentiation of the family started at least by the Middle Jurassic but does not indicate that xerophilic darkling beetles differentiated much earlier than mesophilic groups.

A protonymph of the snout mite genus Odontoscirus Thor, 1913, O. cretacico sp. nov., is described and illustrated from Cretaceous amber of Myanmar is described and illustrated, constituting the earliest fossil species described of the family Bdellidae (ca. 99 Ma). After reexamining the literature and recollected specimens from type localities, we conclude that the following five recent species do not belong to the genus Biscirus and should be transferred to Odontoscirus: O. anomalicornis (Berlese 1916) comb. nov., O. symmetricus (Kramer 1898) comb. nov., O. uncinatus (Kramer 1898) comb. nov., O. norvegicus (Thor 1905) comb. nov., and O. insularis (Willmann 1939) comb. nov. The implications of the fossil record of the family is discussed.

AbstractThe fossil record of the family Camerobiidae has been represented by only one species, Neophyllobius succineus Bolland and Magowski, 1990, described from Eocene Baltic amber. These prostigmatan mites are distinguishable by their distinctly long and slender stilt-like legs, and they are associated with aboveground vegetation where they hunt for other small invertebrates. This paper enhances the knowledge of fossil stilt-legged mites. Two new fossil species, N. electrus new species and N. glaesus new species, are described from samples of Baltic amber, and remarks on their morphology and taphonomy are provided. The discovery is complemented with a discussion on morphological singularities (the shape of the prodorsum, the location of setae h1 and h2 in living specimens, and lengths of genual setae), an anomaly of hypertrophied seta (found in the N. glaesus holotype), and some biogeographical issues.UUID: http://zoobank.org/d1602384-ae4f-4f90-b4a1-6cdedd77c9e1

Two New Species

The dipteran family Bolitophilidae, with the single extant genus Bolitophila, is a small family of mycophagous flies. In marked contrast to related families such as Sciaridae and Mycetophilidae, the family has a poor fossil record with no definite species assigned to the genus. In addition, the position of the extinct Cretaceous subfamily Mangasinae Kovalev, 1986 (described in Bolitophillidae) has been controversial and it has been suggested that species in this clade may belong to other sciaroid families. This situation is made worse by misplacement of the type specimen. We herein describe two new species of Bolitophila, Bolitophila warreni sp. nov. from the 46-million-year-old Kishenehn Formation in Montana, USA and Bolitophila rohdendorfi sp. nov. from Baltic amber. Bolitophila pulveris Lewis, 1969 is reassigned to Sciaroidea incertae sedis. The subfamily Mangasinae is reviewed and its position within the Bolitophilidae confirmed. Two new species of Mangas, M. kovalevi sp. nov. and M. brevisubcosta sp. nov., both from the Lower Cretaceous of Khasurty in Western Transbaikalia, are described.

Lepidopsocids are well diversified in recent fauna, but fossil records remain very scarce. Echmepteryx (Loxopholia) dominicanus sp. nov. from Dominican amber is herein described and illustrated. This species is attributed to subfamily Lepidopsocinae Enderlein, 1903 and assigned to genus Echmepteryx Aaron, 1886. This new record is the second oldest lepidopsocid. It is also the first species in this family to be described from Dominican amber and the only fossil record of Lepidopsocinae.

Although the family Kateretidae has fewer than 100 described extant species, its fossil record is growing. The description given here of Electrumeretes birmanicus gen. et sp. nov. and Polliniretes penalveri gen. et sp. nov. brings the number of fossil species in Kateretidae up to nine. Eight of the fossil species have been described from amber deposits and six are from the Cretaceous. All the Cretaceous fossil species and one from the Eocene share atypically short elytra and three dorsally exposed abdominal tergites, whereas in Recent relatives, even though they have shortened elytra, only the pygidium and a part of the preceding one or two abdominal tergites are exposed. It is suggested that shortened elytra (brachelytry) represents an ancestral state and that elytra may have become secondary longer in extant relatives.

Pseudochiridium lindae n. sp. is described from Dominican amber (Miocene), representing the first fossil record of the family Pseudochiridiidae. The extant species Pseudochiridium insulae Hoff, 1964 is newly recorded from the Dominican Republic. Paracheiridium vachoni Vitali-di Castri, 1970 is transferred to the genus Pseudochiridium With, 1906 (n. comb.). The correct publication date for family-group names based on Cheiridiinae Hansen is shown to be 1894.

The flat bug family Aradidae is represented to date in Dominican Amber only by two species: Calisiopsis brodzinskyorumFroeschner, 1992 and Mezira scheveni Heiss, 2000 belonging to the subfamilies Calisiinae and Mezirinae respectively.Now two fossil species sharing the characters of the extant genera Nesoproxius Usinger & Matsuda, 1959 (N.latocanusn.sp.) and Carventus Stål, 1865 (C. bechlyi n.sp.), and one tentatively assigned to Acaricoris Harris & Drake, 1944 (A.robertae n.sp.), are described and illustrated below. Another specimen cannot be placed into an extant genus, and Proneoproxius n.gen. is proposed to accommodate P.cornutus n.sp.
