A new species of the genus Cyrtodactylus is described from Dien Bien Province, northwestern Vietnam based on morphological and molecular data. Cyrtodactylus ngati sp. nov. can be distinguished from remaining congeners by the following combination of characters: maximum SVL 69.3 mm; dorsal pattern consisting of six dark irregular transverse bands between limb insertions; inter-supranasals one; dorsal tubercles present on occiput, body, hind limbs and on first half of tail; 17–22 irregular dorsal tubercle rows at midbody; lateral folds clearly defined, with interspersed tubercles; 32–38 ventral scales between ventrolateral folds; 13 precloacal pores separated by a diastema of 5/5 poreless scales from a series of 7/7 femoral pores in enlarged femoral scales; precloacal and femoral pores absent in females; 1–3 postcloacal tubercles on each side; transversely enlarged median subcaudal scales absent. In the molecular analyses, the new species is shown to be the sister taxon to C. interdigitalis from Thailand. This is the 47th species of the genus Cyrtodactylus and the first member of the C. brevipalmatus species group recorded from Vietnam.

AbstractCopris incertus Say, 1835 (Coleoptera: Scarabaeidae: Scarabaeinae: Coprini) has been described as a New World coprophagous scarab distributed from Mexico to Ecuador with large discontinuities in its range between the Yucatán province and Costa Rica. The C. incertus species complex of the Copris minutus (Drury, 1773) species group consists of C. incertus, Copris laeviceps Harold, 1869, and Copris lugubris Boheman, 1858. Based on external morphology and male genitalia, we discovered that multiple species have been classified as C. incertus. Of these species, five are new: Copris amazonicusnew species, Copris brevicornisnew species, Copris davidinew species, Copris moroninew species, and Copris susanaenew species. Herein, we revise the organisation of the C. incertus species complex and propose a new species complex, the C. laeviceps species complex, which includes: C. davidi, Copris igualensis Warner, 1990, and C. laeviceps, formerly included in the C. incertus species complex. We provide an identification key along with species distribution maps, images of habitus, and diagnostic characters.

Abstract Background and Aims Through careful field examination of the growth habit of the gametophytes and sporophytes of Hymenasplenium volubile across an ontogenetic series, we aim to understand better the evolution of epiphytism in this poorly understood group of ferns Methods We made field observations of H. volubile sporophytes and gametophytes, and brought specimens back to the lab for microscopic analysis. In the field, sporophytes at each ontogenetic stage were photographed to document the species’ growth habit. We used an existing phylogeny to optimize growth form of New World Hymenasplenium. Key Results Young sporophytes were at first fully epiphytic and produced one or two long feeding roots that extend to the soil where they branch profusely. The feeding roots remain in contact with the soil throughout the life of the plant. Thus, H. volubile is a hemiepiphyte. While immature, gametophytes are appressed to the tree trunk, but, as their gametangia mature, their lower margin lifts upward, imparting a shelf-like appearance to the thallus. The thallus attaches to the substrate by branched rhizoids produced along the margin of the thallus in contact with the substrate. Conclusions Hemiepiphytes are a key link in the evolution of epiphytic ferns and may act as a bridge between the forest floor and the canopy. Our finding is the first report of hemiepiphytism in Aspleniaceae, a large lineage with many epiphytic and terrestrial taxa. This work serves as an important model to understand the evolution of epiphytism in this group specifically and in ferns in general. The majority of our understanding of fern gametophyte biology is derived from laboratory studies. Our efforts represent a fundamental contribution to understanding fern gametophyte ecology in a field setting.

DNA molecular data are used to generate a phylogeny for the micropezid subfamily Taeniapterinae. Thirty-two taeniapterine species were sampled, including 10 of the 20 New World genera recognized by Steyskal, as well as one genus formerly treated as a synonym of Poecilotylus Hennig (Hemichaeta Steyskal). Five species from the Micropezinae were included as outgroups. A total DNA dataset of 4705 bp, including mitochondrial genes (12S and cytochrome c oxidase I (COI)) and nuclear coding genes (wingless and CAD), was analysed using maximum parsimony and Bayesian inference. The genus Taeniaptera Macquart was found to be non-monophyletic with respect to the remainder of the Taeniapterini analysed here. Taeniaptera is restricted to the Taeniaptera trivittata Macquart species group, Mitromyia Cresson is resurrected to contain the Taeniaptera grata (Wulp) species group, and Paragrallomyia Hendel is resurrected to contain most species previously considered Taeniaptera. Poecilotylus is recognized as a paraphyletic group awaiting further research.

Vespula akrei Landolt sp. nov. is described from Guatemala. The first record of Vespa crabro L. in Guatemala is given, and Vespula inexspectata Eck from Mexico is re-described. We place Vespula akrei sp. nov. in the Vespula vulgaris (L.) species group (= Paravespula Bluthgen) based on morphology, color pattern, and DNA sequences from two mitochrondrial genes. It is presently known only from the Sierra de las Minas mountain range in southeastern Guatemala.

A new species of Gonatocerus Nees (Mymaridae) is described from the states of San Luis Potosí and Tamaulipas in Mexico, with additional records from Argentina and Peru. Type specimens of G. uat S. Triapitsyn sp. n. were reared in Mexico from the eggs of proconiine sharpshooters (Cicadellidae: Cicadellinae: Proconiini) in the genera Homalodisca Stål and Oncometopia Stål. Taxonomic and molecular evidence from five gene regions (28S-D2, ITS1, ITS2, COI, COII) is provided to help differentiate the new species from the morphologically similar taxon, G. ashmeadi Girault, which also belongs to the ater species group of Gonatocerus.

The discovery of Camilla glabra (Fallen) in Ottawa, Canada, is the first record of the existence in the New World of any member of the interesting little family Camillidae. A single male specimen taken June 15, 1954, by D. G. F. Cobb while collecting insects in her garden, would seem to indicate the species is established here.The family Camillidae consists of the single genus Camilla Haliday, which for many years was assigned to the family Drosophilidae. Frey, (1921) considered it sufficiently differentiated from the Drosophilidae to warrant separate status and erected the family Camillidae to receive it. Duda (1934), Wheeler (1952, p. 164), and Collin (1956) all recognized the group as a family distinct from the Drosophilidae. More recently, Hennig (1958, p. 665) placed it as a separate family in the Drosophiloidea, pointing out that while it has certain characters in common with Curtonotidae and Drosophilidae, it shows even more affinities with Diastatidae and Ephydridae.
