Glassfrogs (family: Centrolenidae) represent a fantastic radiation (~150 described species) of Neotropical anurans that originated in South America and dispersed into Central America. In this study, we review the systematics of Ecuadorian glassfrogs, providing species accounts of all 60 species, including three new species described herein. For all Ecuadorian species, we provide new information on the evolution, morphology, biology, conservation, and distribution. We present a new molecular phylogeny for Centrolenidae and address cryptic diversity within the family. We employ a candidate species system and designate 24 putative new species that require further study to determine their species status. We find that, in some cases, currently recognized species lack justification; specifically, we place Centrolene gemmata and Centrolene scirtetes under the synonymy of Centrolene lynchi; C. guanacarum and C. bacata under the synonymy of Centrolene sanchezi; Cochranella phryxa under the synonymy of Cochranella resplendens; and Hyalinobatrachium ruedai under the synonymy of Hyalinobatrachium munozorum. We also find that diversification patterns are mostly congruent with allopatric speciation, facilitated by barriers to gene flow (e.g., valleys, mountains, linearity of the Andes), and that niche conservatism is a dominant feature in the family. Conservation threats are diverse, but habitat destruction and climate change are of particular concern. The most imperiled glassfrogs in Ecuador are Centrolene buckleyi, C. charapita, C. geckoidea, C. medemi, C. pipilata, Cochranella mache, Nymphargus balionotus, N. manduriacu, N. megacheirus, and N. sucre, all of which are considered Critically Endangered. Lastly, we identify priority areas for glassfrog conservation in Ecuador.

This study reviews the family Macrochelidae in Turkey, with new information about species diversity. Nothrholaspis scutivagus sp. nov., Macrocheles niksarensis sp. nov. and Holostaspella bidentata sp. nov. are described as new species from Turkey. Nothrholaspis scutivagus has a characteristic dorsal shield chaetotaxy, and post-genital platelets that are sometimes fused to the ventri-anal shield. Macrocheles niksarensis has 29 pairs of pilose dorsal shield setae and a machete-like cheliceral dorsal seta. The genus Holostaspella is recorded from Turkey for the first time, on the basis of H. bidentata. Macrocheles peniculatus and M. insignitus are reported from Turkey for the first time. Also, Macrholaspis recki and M. evansi are presented here with some notes on the Turkish specimens.

Three New Species

Resuming published and own data, a revision of classification of Chaetognatha is presented. The family Sagittidae Claus & Grobben, 1905 is given a rank of subclass, Sagittiones, characterised, in particular, by the presence of two pairs of sac-like gelatinous structures or two pairs of fins. Besides the order Aphragmophora Tokioka, 1965, it contains the new order Biphragmosagittiformes ord. nov., which is a unique group of Chaetognatha with an unusual combination of morphological characters: the transverse muscles present in both the trunk and the tail sections of the body; the seminal vesicles simple, without internal complex compartments; the presence of two pairs of lateral fins. The only family assigned to the new order, Biphragmosagittidae fam. nov., contains two genera. Diagnoses of the two new genera, Biphragmosagitta gen. nov. (type species B. tarasovi sp. nov. and B. angusticephala sp. nov.) and Biphragmofastigata gen. nov. (type species B. fastigata sp. nov.), detailed descriptions and pictures of the three new species are presented.

Taxonomic Studies

Psychotria subg. Heteropsychotria Steyerm. has been shown by morphological and molecular analyses to be polyphyletic. Most of its species, including its type, belong to Palicourea Aubl. (“Pal.”). Thirty-two species of this group are reviewed here, and 17 species in Psychotria L. are transferred to Palicourea and one to Rudgea Salisb. Two replacement names, Pal. agudeloana C. M. Taylor and Pal. tabayensis C. M. Taylor, are published. Taxonomic studies here clarify circumscriptions of similar, often-confused species for several distinctive species groups found variously in Mesoamerica and the Andes: the Palicourea aschersonianoides group, the Palicourea galeottiana group, the Palicourea sulphurea group, and the Palicourea tristis group. Three new species of Palicourea are described: Pal. aschersonianula C. M. Taylor, Pal. gonzaleziana C. M. Taylor, and Pal. wachterae C. M. Taylor. Nineteen names are newly typified, and infrageneric classifications are noted for the species of Palicourea studied.

AbstractMorphological, life history, and distributional data are presented for North American species of the subgenus Stygomomonia (sensu stricto) Szalay, 1943. Adults of the seven previously recognized species are redescribed, and deutonymphs of five of these species are described for the first time. Two species, S. (s.s.) neomexicana Cook and S. (s.s.) occidentalis Cook are substantially revised on the basis of an examination of the types and extensive series of newly collected specimens. Three new species are described, S. (s.s.) californiensis on the basis of deutonymphs and adults, and S. (s.s.) imamurai and S. (s.s.) cooki on the basis of adults. A new diagnosis of the subgenus is proposed and discussed, the relationships of the various species are discussed, and a key to deutonymphs and adults of North American species is presented. New distributional data are presented for all species, and dispersal patterns from Pleistocene refugia are discussed.

Three New Species

Three new species of Chrysomelidae with extraordinary extensions of the male mandibles are described: Scaphodius drehu sp. nov. and S. ferox sp. nov. (Cryptocephalinae), from New Caledonia, and Chaloenus gajah sp. nov. (Galerucinae), from Borneo. Designation of the type species of Chaloenus Westwood, 1861, is clarified. Synonymy of Scaphodius Chapuis, 1874, with Nyetra Baly, 1877, is supported. Four species of Ditropidus Erichson, 1842, described from New Caledonia, but hitherto regarded as nomina nuda, are shown to be available and are placed in Scaphodius: S. aeneus (Fauvel, 1907), comb. nov., S. nitidus (Fauvel, 1907) comb. nov., S. striolatus (Fauvel, 1907) comb. nov., S. sulcatus (Fauvel, 1907) comb. nov. Ditropidus opacicollis Fauvel, 1907, is also transferred to Scaphodius, as S. opacicollis (Fauvel) comb. nov. The genus Ditropidus does not occur onNew Caledonia. Male mandible enlargment in the Chrysomelidae is reviewed: it is common in Cryptocephalinae, but otherwise restricted to a few species of Chrysomelinae, Eumolpinae and Galerucinae. Possible reasons for its distribution in the Chrysomelidae are discussed.

Partial Revision

The genus Robinsonia Grote, 1866 is partially reviewed following a large DNA barcode campaign. In the Robinsonia praphoea Dognin, 1906 group three new species are described: R. simulans sp. n. from French Guiana, up to now confused with R. praphoea itself and then R. decaensi sp. n. and R. maranhensis sp. n. both from the lower Amazon. R. drechseli sp. n. is described from Paraguay and R. inexpectata sp. n., a species close to R. mera (Schaus, 1910) from Costa Rica, is described as new from Peru and Bolivia. Finally the full species status is confirmed for R. flavicorpus Dognin, 1910 which is found to be differentiable from R. marginata Rothschild, 1909. All types are figured along with the male genitalia for most and some female genitalia for all studied species.

Three new species of oribatid mites of the family Galumnidae are described from soil and coniferous litter of Hogsback State Forest, Eastern Cape Province, South Africa. Pilogalumna hogsbackensis sp. nov. differs from Pilogalumna tenuiclava and P. ornatula by the presence of elongate oval postanal porose area and narrowly unilaterally dilated bothridial head. Pergalumna amatholensis sp. nov. differs from Pergalumna distincta by the presence of smaller body size, rounded rostrum, unilaterally dilated bothridial head, one pair of notogastral porose areas Aa, and the localization of opisthonotal gland opening and lyrifissure im. Stictozetes ihaguensis sp. nov. differs from all species of the genus by presence of bothridial seta with narrowly dilated head and median pore in both genders. An identification key to known species of Stictozetes is presented.
