First Time

For the first time eggs, larvae and pupae obtained by rearing are described for Astrapaeus, a monotypic West Palearctic rove beetle genus of a puzzling phylogenetic position within the megadiverse tribe Staphylinini. Morphology of the immature stages of Astrapaeus ulmi is compared to that of other members of the tribe and discussed in a phylogenetic context. Contrary to conventional systematics and in accordance with recently developed phylogenetic hypotheses based on morphology of adults, larval morphology supports the non-Quediina affiliation of Astrapaeus. Eggs and pupae provided fewer characters with putative phylogenetic signal. Under laboratory conditions, a peculiar preference for isopod prey was observed for A. ulmi. However, this could not be evaluated in an evolutionary context because of the lack of data on the diet of this and related taxa in nature.

A New Species

The genus Pselactus in the Cape Verde Islands is reviewed. Pselactus obesulus (Wollaston, 1867) from São Vicente is redescribed and P. strakai sp. nov. from São Nicolau is described. Both species are diagnosed and illustrated; their larvae are described, larval morphology is discussed and the current state of knowledge about immature stages of Cossoninae is summarized. The systematic position of the genus within Onycholipini is reviewed, and the placement of genus in Cossoninae is discussed. A short note on biogeography of Pselactus is provided.

Our current knowledge on the crocodyliform evolution is strongly biased towards the skull morphology, and the postcranial skeleton is usually neglected in many taxonomic descriptions. However, it is logical to expect that it can contribute with its own phylogenetic signal. In this paper, the changes in the tree topology caused by the addition of the postcranial information are analysed for the family Allodaposuchidae, the most representative eusuchians in the latest Cretaceous of Europe. At present, different phylogenetic hypotheses have been proposed for this group without reaching a consensus. The results of this paper evidence a shift in the phylogenetic position when the postcranium is included in the dataset, pointing to a relevant phylogenetic signal in the postcranial elements. Finally, the phylogenetic relationships of allodaposuchids within Eusuchia are reassessed; and the internal relationships within Allodaposuchidae are also reconsidered after an exhaustive revision of the morphological data. New and improved diagnoses for each species are here provided.

The development of lonchaeid flies of the genus Earomyia Zetterstedt, 1842 (Diptera: Lochaeidae) in Veratrum album L. stems is reported for the first time. Larvae were collected in July 2015 in Serbia (Crni Vrh) in mountains at 988 m a.s.l. from inside a blackened decaying part of the stem at a point 1/3 from the apex. No other insects were discovered in the same part of stem. Emergence of adult E. crystallophila (Becker, 1895) occurred under laboratory conditions in January 2016. The larva and puparia are described for the first time.

Abstract The life history, morphology, and biology of the immature stages and phylogenetic relationships of Rotunda rotundapex (Miyata & Kishida, 1990) are described and illustrated for the first time. The species is univoltine: eggs hatch in spring (March or April) and the life cycle from egg to adult is completed in about 3 wk, with larvae developing rapidly on young leaves of the host plants, Morus australis and to a lesser extent Broussonetia monoica (Moraceae), and adults emerging in April–May. Eggs are laid in clusters on twigs of the host plant, are covered by scales during female oviposition, and remain in diapause for the remainder of the year (i.e., for 10–11 mo). Larvae (all instars) are unique among the Bombycidae in that they lack a horn on abdominal segment 8. A strongly supported molecular phylogeny based on six genes (5.0 Kbp: COI, EF-1α, RpS5, CAD, GAPDH, and wgl) representing seven genera of Bombycinae from the Old World revealed that Rotunda is a distinct monotypic lineage sister to Bombyx. This phylogenetic position, together with morphological data of the immature stages (egg and larval chaetotaxy), supports the current systematic classification in which the species rotundapex has been placed in a separate genus (Rotunda) from Bombyx in which it was previously classified.

The elmid beetle Orientelmis parvula (Nomura & Baba, 1961) is a rare and endangered species in Japan. Mouth parts and genitalia in adults of both sexes and larval morphology are described based on scanning electron microscope observations. The larva of the genus Orientelmis Shepard, 1998 is described for the first time. The systematic position of the genus is discussed based on the morphology and a phylogenetic tree inferred from the mitochondrial COI, and nuclear ArgK and 18S gene sequences. A new key for larvae of known species and genera of Japanese Elmidae is given.

AbstractImmature stages of the uniquely phytophagous staphylinid, Himalusa thailandensis Pace, Klimaszewski, and Center, 2010 (Coleoptera: Staphylinidae: Aleocharinae) are described. Adults chew or scrape leaf surfaces while larvae bore into leaf petioles where they mature, and then drop to the ground to pupate in silken cocoons. Compared to other aleocharines, the larval body form is unusually compact and rotund, and may be an adaptation to living within the confines of plant tissue. Mandible and maxilla morphology is unique among known larval aleocharines in being robust and dentate, and we suggest this is adaptive for scraping and squeezing plant tissue. The larval defensive gland is ribbed and gland sac ducts are kinked and apically bifid. We suggest that H. thailandensis may share this derived gland morphology with Autaliini, Bolitocharina, Gyrophaenina, Homalotina, Leptusina, and Silusina of Homalotini, and possibly Liparocephalini. The morphology and ecology detailed here for H. thailandensis is the first comprehensive description of immature stages among aleocharines where adults feed externally on plants.

External morphology of larvae belonging to three unidentified genera of the rove-beetle subfamily Leptotyphlinae (Coleoptera: Staphylinidae) collected in Mexico, Chile and Australia, respectively, is described and illustrated. Larvae of Leptotyphlinae can be distinguished from all other Staphylinoidea larvae by the combination of their small size (maximum documented head width 0.128 mm), along with complete absence of eyes, lyriform frontal ecdysial lines, long coronal suture extending for about 40% of head length, short antennae not longer than 1/3 of head length, non-serrate mandibles with a single pre-apical tooth, tibiotarsi swollen in middle with two ventral spines, and indistinctly articulated short urogomphi not longer than twice their basal width. At least some of these characters are likely to support monophyly of the subfamily. Leptotyphlinae are hypothesized to belong to the Staphylinine Group of subfamilies sharing with at least some of them the following larval characters: labrum fully fused with clypeus; posterior tentorial arms extremely thin, thread-like and more than 20 times longer than wide; posterior tentorial pits short, rounded to elongate; cardo lacking transverse sclerotized ridge. The sister-group relationships of Leptotyphlinae to a clade of Pseudopsinae+Paederinae+Staphylininae is hypothesized with the following larval characters in support: lyriform frontal arms; each maxilla articulated laterally to head capsule by a condyle; maxillary mala parallel-sided (=finger-shaped) and articulated to stipes. A larval identification key to all three presently described genera is given.

First Descriptions

In this paper, the mature larva and pupa of Bagous claudicans are described and illustrated for the first time. Measurements of younger larval instars are also given. The biology of the species is discussed in association with larval morphology and feeding habits. Overall larval and pupal morphological characters of the genus Bagous are presented. Confirmation of the larva identification as Bagous claudicans species was conducted by cytochrome oxidase I (COI) sequencing. DNA barcoding was useful for specimen identification of larval stages. The systematic position of the species within the Bagous collignensis-group, based on morphological and molecular results, is also discussed.
