The genus Platystigma Kennedy, 1920 is revalidated based mainly on the third segment of the penis that is plate-like, whereas in the other Pseudostigmatidae it is a flagellum. Dijkstra et al (2014) have merged this family into the Coenagrionidae. However, we prefer to maintain the long-used name Pseudostigmatidae until more detailed phylogenetic studies with more sampling are done. Eight species are here considered in the genus, three of which are described as new: P. humaita, P. minimum and P. quadratum. The genus is divided in two species group, jocaste and quadratum, the latter studied here. The hitherto unknown male of P. martinezi (Machado 1985) is described for the first time. Evidence for exophytic oviposition is presented in at least one species of the genus. A key is provided for the species of the quadratum group.

AbstractThree new species of snapping shrimps of the genusAlpheusare described from the Persian Gulf. These belong to theAlpheus edwardsiispecies-group, which is mainly characterized by unarmed orbital hoods and the presence of dorsal and ventral notches on the palm of the major chela.Alphus ankerisp. nov. shows a close affinity toA. pacificusDana, 1852 andA. heronicusBanner & Banner, 1982 bearing no balaeniceps crests in both sexes on the dactylus of the minor chela, and the merus of the major chela of both sexes are unarmed. This species differs from the closely related species by the absence of an overhanging proximal shoulder in the major chela. The other rock crevice inhabiting species,A. mohammadpourisp. nov. is diagnosed by exhibiting sexual dimorphism in its balaeniceps crests and the armed merus of the major chela. These two characters are similar to those recorded for three sandy/rubble dwelling species:A. inopinatusHolthuis & Gottlieb, 1958,A. lobidensDe Haan, 1849 andA. australiensisBanner & Banner, 1982. This new species is distinguishable from these latter species by the shape of the minor chela and colour pattern. A coral inhabiting speciesA. abumusasp. nov. appears to be closely related toA. maindroniCoutière, 1898, showing an armed merus of the major chela and the absence of spine-like seta on the ischia of the third legs. This last new species is easily discriminated fromA. maindroniby longer antennular segments, a markedly concave frontal margin between the rostrum and orbital hood, and a different colour pattern.

Three species of Lachesilla, in species group rufa, from the Sierra Tarahumara, Chihuahua, Mexico, are here described and illustrated: L. byei n. sp., L. furthi n. sp., and L. raramuri n. sp. Two of them belong in Subgroup IIb of the species group, one showing affinities with L. sommermanae García Aldrete and L. yakima Mockford & García Aldrete, the second one showing affinity with L. salamana García Aldrete. The third species belongs in Subgroup I of the species group, showing affinities with L. aspera García Aldrete and L. chiricahua García Aldrete. The especies here described raise to seven the number of species of Lachesilla in the Sierra Tarahumara.

Three New Species

Three new species of the genus Oligaphorura are described from southwestern China (O. wanglangensis sp. nov.) and Russian Far East (O. ussurica sp. nov. and O. kedroviensis sp. nov.). The first species is most similar to O. inya (Weiner & Kaprus’, 2014) known from the Altai Mountains, and can be distinguished from the latter by larger body size and the number of ventral psx (00/000/121101m in O. wanglangensis sp. nov. vs 1/000/212101m in O. inya). The other two species, together with O. montana Weiner, 1994, O. pseudomontana Sun & Wu, 2012 and O. chankaensis Sun & Wu, 2012, form a distinct species-group characterized by the presence of 4+4 pso on antennal base and full-sized anal spines. Both these new species differ from the known congeners of this group by having only 2+2 posterior pso on the head. O. ussurica sp. nov. and O. kedroviensis sp. nov. can be separated due to different number of abdominal pso, i.e. 5(6)5554 in the former vs 44454 in the latter species.

A new species of Darwin wasp of the genus Dicamptus Szépligeti (Hymenoptera: Ichneumonidae: Ophioninae), D. curvus Pham, Matsumoto & Shimizu sp. nov., is described on the basis of type specimen from Lai Chau Province, northwest Vietnam. The new species probably belongs to the giganteus species group and is easily distinguishable from the other species of the group by the smaller indices of fore wing AI and CI as well as the form of sclerites. Two species, D. cantoni Gauld & Mitchell and D. reticulatus (Cameron), are recorded for the first time from Vietnam; and additional distribution records for D. nigropictus (Matsumura) in Vietnam are provided. Through the present study, a total of four Dicamptus species have been recognized in Vietnam and illustrated.

Three new species of Monepidosis Mamaev, 1966, a Holarctic genus of Porricondylinae (Diptera, Cecidomyiidae), are described: M. heterocera sp. nov. from Sweden and Germany, M. scepteroides sp. nov. from Sweden, and M. shikokuensis sp. nov. from Japan. A new porricondyline genus, Antipodosis gen. nov., is introduced for eight new species from New Zealand, named A. australis gen. et sp. nov., A. elongata gen. et sp. nov., A. granvillensis gen. et sp. nov., A. pureora gen. et sp. nov., A. rakiura gen. et sp. nov., A. rotoiti gen. et sp. nov., A. rotoroa gen. et sp. nov., and A. waipapa gen. et sp. nov. Male genitalic morphology indicates that Monepidosis and Antipodosis gen. nov. are closely related, together forming the Monepidosis group of genera, which stands out from the other Porricondylini. Monepidosis spatulata Spungis, 2006, a species originally described from Latvia and Lithuania, is for the first time reported to occur in Sweden.

Epiphytic Bromeliads

A survey of the camerobiid mites living on epiphytic bromeliads and the forest floor of a Mexican tropical dry forest was carried out. We found three new species of the genus Neophyllobius, which are described in this paper; the first two, namely N. cibyci sp. nov. and N. tepoztlanensis sp. nov., were both found inhabiting bromeliads (Tillandsia spp.) and living on two tree species (Quercus obtusata and Sapium macrocarpum); the third, N. tescalicola sp. nov., was found in soil and litter under Q. obtusata. These three new species can be differentiated from other species in the genus by a combination of morphological characters in adult females, mainly those setae on femora and genua I. The idiosoma and leg setal ontogeny of a camerobiid mite is presented for the first time in this paper, illustrating chaetotaxic notations and their relative positions in N. cibyci sp. nov. larva, protonymph and adults (female and male), and establishing setal homologies among instars. Setal homology with other species in the cohort Raphignathina is briefly discussed. Additionally, a compilation and an identification key to all known species of camerobiid mites in Mexico is provided.

A resumé of the genus Mylonchulus is presented, including three new species which are described and illustrated, Mylonchulus prodenticulatus, M. sigmaturellus, and M. solus. Males of M. brevicaudatus, M. incurvus, M. index, M. montanus, and M. striatus are described and figured for the first time. Several known species from various parts of the world are redescribed and figured. Relationship of amphid aperture width to the length and width of the buccal cavity and its position in this genus was studied and evaluated for use in taxonomy. Two taxonomic keys are included, one of all known females, the other of all known males.
