A New Species

A new species, Janzenella theia Bremer & Talamas, sp. nov., is described from Baltic amber, which is the second known species of the family Janzenellidae (Platygastroidea). Synchrotron scanning was performed to observe internal structures and external morphology that was occluded by turbidity in the amber matrix surrounding the specimen.

A new species of the extant spider family Anapidae is described from a fossil mature male in Eocene amber from the Baltic region and tentatively assigned to the genus Balticoroma Wunderlich, 2004. Phase contrast X-ray computed micro-tomography was used to reveal important features that were impossible to view using traditional microscopy. Balticoroma wheateri new species is easily diagnosed from all other anapids by having clypeal extensions that run parallel to the ectal surface of the chelicerae and in having the metatarsus of the first leg highly reduced and modified into what is presumably a y-shaped clasping structure. Although only a single extant anapid species occurs in northern Europe, the family was diverse in the Eocene. The discovery of yet another anapid species in Baltic amber supports the idea that Eocene European forests may have been a hotspot of evolution for this family of spiders.

Plesiomorphic Character

Succinoraphidia radioni sp. nov. (Raphidiidae) is described from the late Eocene Rovno amber, Ukraine. The genus also includes two species from contemporaneous Baltic amber, i.e., S. exhibens Aspöck & Aspöck, 2004 and S. baltica (Carpenter, 1957), comb. nov. The venation of Succinoraphidia is analysed. It possesses several plesiomorphic character states at the family level, and the monotypic subfamily Succinoraphidinae represents a basal group within the family or possibly even a potential stem group of Raphidiidae. All diagnostic character states of Succinoraphidia (except the structure of the pterostigma) are found in a few Cretaceous species of the paraphyletic Mesoraphidiidae, but some of these are not found in the extant Raphidiidae.

A New Species

Summary A new species of fossil mermithid, Heydenius simulphilus sp. n. (Nematoda: Mermithidae), is described from two parasitic juvenile specimens adjacent to a male black fly (Diptera: Simuliidae) in Baltic amber. It is proposed that the nematodes emerged from their developmental sites in the haemocoel of the black fly host through a wound in the abdomen of the latter, as indicated by the release of a droplet of haemolymph and damaged cuticle. Various internal structures of the nematodes are identified and related to those found on extant developing mermithids. This is the first fossil record of mermithid parasitism of a black fly.

A New Species

Beginning in eastern Cuba, a systematic survey on the aquatic beetle fauna of that country is presently being carried out.We present a comprehensive account of the six species of the family Hydraenidae (Insecta: Coleoptera) so far collectedin this region. A new species, Hydraena franklyni is described. Detailed data on the new record of H. guadelupensis andthe four previously known Cuban species are also included. Remarks on their external morphology, descriptions of somemorphological features not previously described, distributional maps, and notes on their ecology are given for all sixspecies. In order to facilitate their identification, a simple key to adults of the six species is provided. Although the faunaof Hydraenidae in eastern Cuba may not include further species, the total Cuban fauna of this family is not yet completely known.

A New Species

A new species of the family Natricidae Bonaparte is described from a single specimen obtained in Arunachal State, northeastern India. On the basis of its external morphology and of its dentition on the upper maxilla, i.e. 24 + 3 distinctly enlarged teeth separated by a short diastema, it is referred to the genus Hebius Thompson. Hebius lacrima spec. nov. is distinguished from other species of the genera Hebius, Amphiesma Duméril, Bibron & Duméril and Herpetoreas Günther, by the combination of an elongate body, 19 dorsal scale rows at midbody, a distinctive broad, white band on the supralabials interrupted by a dark blotch below the eye, absence of dorsolateral stripes replaced by series of transversally elliptical or divided dorsolateral spots, a cream venter with lateral dark blotches, and scales of the first dorsal scale row entirely smooth. The interrupted, broad, lateral stripe of the head differentiates Hebius lacrima spec. nov. from all other species of the genera Hebius and Herpetoreas inhabiting the Indo-Himalayan and Indochinese Regions. This new species is compared in detail with other Asian species of Natricidae having 19 dorsal scale rows.

ABSTRACTThe first representative of Tipulomorpha in Early Eocene Cambay amber from India is described. The new find belongs to the genus Dicranomyia in the family Limoniidae. This genus has a worldwide distribution today and is relatively common in Eocene Baltic amber. A new species belonging to the subgenus Dicranomyia is described as Dicranomyia (Dicranomyia) indica sp. nov.

The genus Rapisma McLachlan, 1866 (montane lacewings) is a rare and little known group of the family Ithonidae (Insecta: Neuroptera). There have been 21 described species of Rapisma, and all of them are distributed from East Asia, South Asia and Southeast Asia. Here I report a new species of Rapisma from northwestern Yunnan, China, namely Rapisma weixiense sp. nov. The new species belongs to a group of Rapisma species with very short antennae.

Abstract During a parasitological survey of fishes at Iguazu National Park, Argentina, specimens belonging to the allocreadiid genus Auriculostoma were collected from the intestine of Characidium heirmostigmata. The erection of the new species is based on a unique combination of morphological traits as well as on phylogenetic analysis. Auriculostoma guacurarii n. sp. resembles four congeneric species – Auriculostoma diagonale, Auriculostoma platense, Auriculostoma tica and Auriculostoma totonacapanensis – in having smooth and oblique testes, but can be distinguished by a combination of several morphological features, hosts association and geographic distribution. Morphologically, the new species can be distinguished from both A. diagonale and A. platense by the egg size (bigger in the first and smaller in the last); from A. tica by a shorter body length, the genital pore position and the extension of the caeca; and from A. totonacapanensis by the size of the oral and ventral sucker and the post-testicular space. Additionally, one specimen of Auriculostoma cf. stenopteri from the characid Charax stenopterus (Characiformes) from La Plata River, Argentina, was sampled and the partial 28S rRNA gene was sequenced. The phylogenetic analysis revealed that A. guacurarii n. sp. clustered with A. tica and these two as sister taxa to A. cf. stenopteri. The new species described herein is the tenth species in the genus and the first one parasitizing a member of the family Crenuchidae.

Four additional species of quill mites of the family Syringophilidae Lavoipierre have now been recorded in England. This includes one new species, Bubophilus aluconis sp. nov., which parasitizes the tawny owl Strix aluco (Strigiformes: Strigidae). It differs from other species of this genus, B. ascalaphus Philips et Norton, 1978 and B. asiobius Skoracki et Bochkov, 2002 by the number of chambers in transverse branch of the peritremes (2-3), the length ratio of setae vi and ve (1:1.6-2), and the lengths of the stylophore and aggenital setae ag1 (180 and 135-145, respectively).
