Contribution to the knowledge of Galumnidae (Acari: Oribatida) in the Oriental region.

We found two species of galumnid mites from Babeldaob Island of the Palau Republic, which is an island located in the western Pacific Ocean. In the present work, we describe Trichogalumna ekaterinae sp. nov., which is clearly different from other known species of Trichogalumna in the specific structure of sensillus, reduced number of notogastral porose areas, and smaller body size. A supplementary description of another species, Galumna flabellifera, which is recorded for the first time in Palau, is given. Furthermore, we discuss aspects of the distribution, diversity and habitat ecology of species belonging to these genera in the Oriental region.

From Zero-Shot Learning to Cold-Start Recommendation

Zero-shot learning (ZSL) and cold-start recommendation (CSR) are two challenging problems in computer vision and recommender system, respectively. In general, they are independently investigated in different communities. This paper, however, reveals that ZSL and CSR are two extensions of the same intension. Both of them, for instance, attempt to predict unseen classes and involve two spaces, one for direct feature representation and the other for supplementary description. Yet there is no existing approach which addresses CSR from the ZSL perspective. This work, for the first time, formulates CSR as a ZSL problem, and a tailor-made ZSL method is proposed to handle CSR. Specifically, we propose a Lowrank Linear Auto-Encoder (LLAE), which challenges three cruxes, i.e., domain shift, spurious correlations and computing efficiency, in this paper. LLAE consists of two parts, a low-rank encoder maps user behavior into user attributes and a symmetric decoder reconstructs user behavior from user attributes. Extensive experiments on both ZSL and CSR tasks verify that the proposed method is a win-win formulation, i.e., not only can CSR be handled by ZSL models with a significant performance improvement compared with several conventional state-of-the-art methods, but the consideration of CSR can benefit ZSL as well.

Additional contributions to the knowledge of Philippine predatory mites mainly of the subfamilies Cunaxinae and Cunaxoidinae (Acari: Prostigmata: Cunaxidae)

A new species of cunaxid mite belonging to the subfamily Cunaxinae, Cunaxa minidiscondyla sp. nov., is described from the Philippines. This species is distinctive by the presence of a small disc-shaped apophysis dorsodistally on the palp telofemur, two spine-like setae on the palp genu, a long spine-like seta on the palp tibiotarsus, an ill-defined propodosomal shield, the absence of a median hysterosomal shield, long hysterosomal setae, and basifemoral and telofemoral chaetotaxy of 4-4-3-1 and 5-5-4-4, respectively. The previously unknown female of Lupaeus longisetus (Cunaxoidinae) and unknown male of Dactyloscirus trifidus (Cunaxinae) are described. A supplementary description is provided for Scutopalus clavatus (Cunaxoidinae) which is recorded for the first time in the Philippines on coconut leaves infested with the scale insect, Aspidiotus rigidus.

New species and records of phytoptids (Eriophyoidea, Phytoptidae) from cinquefoils (Rosaceae, Potentilla) from Serbia and southern Russia

Two new vagrant species of the genus Phytoptus Dujardin (Eriophyoidea, Phytoptidae, Phytoptinae) from Serbia are described: Phytoptus argenteus n. sp. from Potentilla argentea and P. serbicus n. sp. from Potentilla tommasiniana. Remarks on morphology of Phytoptus alchemillae Jočić et al. 2011 collected from Alchemilla plicata in Serbia and supplementary description of infrequently encountered species Phytoptus potentillae Chen et al. 2005 from Potentilla bifurca (Poaceae) based on mummies recovered from dry plant material from southern Russia are given. Sequences of mtCOI barcode region (658 bp) of three Phytoptus species (P. alchemillae, P. argenteus n. sp., and P. serbicus n. sp.) are provided. A brief comparison of pairwise genetic distances between congeneric eriophyoid mites across taxa of Eriophyoidea (including genus Phytoptus) indicates that COI sequences of congeneric eriophyoid mites do not precisely reflect phylogenetic relations of their hosts. This fact may be explained by (a) different rate of the COI evolution in different mite clades associated with phylogenetically related and unrelated hosts or by (b) similar timing of the associations between mites and plants (while having the same rate of COI evolution).

Taxonomy of the Hirtodrosophila melanderi species group (Diptera: Drosophilidae), with descriptions of four new species from southwestern China.

The Hirtodrosophila melanderi species group contains nine known species recorded from either the Old or the New World. All these species were thought to be strict fungivorous drosophilids. In the present study, we give supplementary descriptions for three of these known species, all recorded from Yunnan, southwestern China, H. furcapenis, H. furcapenisoides, and H. longifurcapenis, by examining respective type specimen(s). We then describe four new species of the same group, H. seticlasper Katoh Gao, sp. nov., H. spinicerca Katoh Gao, sp. nov., H. serratifurcapenis Katoh Gao, sp. nov., and H. truncifurca Katoh Gao, sp. nov., all discovered recently from high altitudes (ca. 3,500 to 3,800 m a.s.l.) in Tibet (Xizang), southwestern China. The delimitation of these new species is firstly performed in light of morphology and further with the aid of DNA sequences of the mitochondrial COI (cytochrome c oxydase, subunits I) gene. In addition, a key to all the species of the species group is provided.

Additional notes, corrections and sporophyte descriptions for Mesochaete (Bryopsida: Aulacomniaceae) in Australia.

The genus Mesochaete Lindb. is known from tropical to temperate regions of the east coast of mainland Australia and Lord Howe Island. It includes two species, M. undulata Lindb. and M. taxiforme (Hampe) Watts & Whitel. Leaf size, leaf cell dimensions and aspects of leaf cross-sectional anatomy appear to be the most reliable morphological features to distinguish the species and new information is given in support of their retention as separate species. Incorrect statements in the Flora of Australia and other Australian treatments are rectified. As there are no previous illustrations of the sporophyte of M. taxiforme, or descriptions of the peristome and spores of either taxon, complete illustrations of the two Mesochaete species are presented with a supplementary description of the sporophyte and, where available, SEMs of peristomes and spores. One of the taxa, M. taxiforme, was represented by very little fruiting material. Consequently, only one sporophyte was sacrificed for the SEM work. Morphologically, peristomes and spores of both taxa appear almost identical.

The cacao bud mite, Aceria reyesi (Nuzzaci 1973)—supplementary description, distribution and comparison with Gymnaceria cupuassu Oliveira, Rodrigues & Flechtmann 2012 (Acari: Eriophyidae)
