The genus Holopodostreptus Carl, 1913 is a poorly known monotypic genus endemic to Ecuador. It differs from most other Pseudonannolenidae by a set of characteristics of the gnathochilarium and gonopods. Herein, we provide descriptive notes of males of H. braueri Carl, 1913 based on recently collected material. Females of the species are described for the first time, and images of the vulvae are provided. In addition, we attempt for the first time to place Holopodostreptus in a phylogenetic context. With a total of 14 taxa and 41 morphological characters, and under implied weighting (k = 6), a single most-parsimonious tree is recovered (total fit = 35.86). The genus is recovered as sister-group of Physiostreptus Silvestri, 1903. The clade Holopodostreptus + Physiostreptus is supported by one synapomorphy (absence of setae on the prefemoral process of leg-pair 1 in males) and one homoplastic transformation (narrow telopodite). Based on the phylogenetic results, notes on the subfamilies Pseudonannoleninae, Cambalomminae and Physiostreptinae and a key for all pseudonannolenid genera are provided.

Abstract: Forest clearance, especially in the tropics, leads to habitat loss for many organisms including litter-dwelling arthropods. Among other invertebrates, millipedes (Diplopoda) provide important ecosystem services like decomposition and nutrient cycling in forest ecosystems. Despite their importance, little is known about litter inverte-brates\&$\#$39; response to tropical forest degradation and their role in reforestation. The present article should rather be regarded as a review of millipedes\&$\#$39; occurrence in tropical forests with a pilot study from Madagascar, because the sample size is small and results need to be confirmed. This pilot study investigated the relationship between millipedes and vegetation characteristics in the eastern rainforests of Madagascar, in the region of Andasibe, parts of which are undergoing reforestation.

Vegetation characteristics were measured in ten different forests encompassing different types: remnant rainforest, secondary forest, old Eucalyptus plantations, recently enriched with indigenous tree species, and degraded sites. Millipede species were searched by hand, identified and their occurrence in relation to the environmental characteristics was described. Vegetation characteristics differed between forest types. Old Eucalyptus plantations, secondary forest, and primary rainforest were associated with higher litter depth and more native millipede species than degraded sites and forests afforested with native tree species since 2007. Non-native millipedes occurred in all vegetation formations except the primary rainforest site and did not show any relationship with vegetation characteristics. In contrast, native milli-pedes\&$\#$39; occurrence was related to conditions associated with mature forest, such as high litter depth and high foliage cover. Logistic regression revealed a threshold of litter depth above which native millipedes are likely to occur. The results indicate that native milli-pedes are affected by forest degradation and are incompletely restored even when the afforested forest might approach the original state. Special care should be taken during reforestation efforts, as non-native soil arthropods can be introduced, completely replacing the indigenous biota.

Resum\é: Les cons\équences de la d\éforestation globale sont multiples. Pour la plupart des organismes, la d\éforestation est la cause principale de la destruction des habitats. Les arthropodes qui vivent sur le sol forestier ou dans le feuillage sont ainsi menac\és, surtout dans les for\êts tropicales. Ces organismes sont pourtant indispensables au maintien de la r\ésilience de la for\êt. Dans l\’\écosyst\ème forestier, les millepattes et autres arthropodes sont tr\ès importants pour la mise \à disposition de diff\érents services \écosyst\émiques, par exemple pour leur r\ôle dans le cycle des \él\éments nutritifs, la formation des sols et la d\écomposition. Malgr\é leur importance, peu d\’informations sont disponibles sur la r\éaction des invert\ébr\és suite \à la d\égradation des for\êts et leur r\ôle dans la reforestation.

Cette \étude tient surtout lieu de r\évision de l\’occurrence des millepattes dans les for\êts tropicales avec une \étude pilote men\ée \à Madagascar, dans la mesure o\ù l\&$\#$39;\échantillonnage est r\éduit et que les r\ésultats restent partiels. Cette \étude pilote analyse les relations entre les millepattes et les caract\éristiques v\ég\étales dans les for\êts de l\’Est de Madagascar, dans la r\égion d\’Andasibe. Ces for\êts sont tr\ès diverses et dix types de for\êt ont \ét\é consid\ér\és, \à savoir une for\êt r\écemment d\égrad\ée et une for\êt d\égrad\ée, une for\êt d\égrad\ée et rebois\ée avec des esp\èces arbor\ées indig\ènes en 2007, 2012 ou 2015, des plantations d\’Eucalyptus abandonn\ées depuis 1930 ou 1909, deux for\êts secondaires, une for\êt primaire. Dans ces diff\érents types de for\êt, les caract\éristiques de la v\ég\étation ont \ét\é enregistr\ées et des millepattes ont \ét\é r\écolt\és \à la main. Les esp\èces de millepattes ont \ét\é identifi\ées et leur occurrence ont \ét\é analys\ées par rapport aux caract\éristiques de la v\ég\étation. Les vieilles plantations d\’Eucalyptus et les for\êts secondaire et primaire \étaient caract\éris\ées par une couche plus \épaisse de feuilles et davantage d\’esp\èces de millepattes indig\ènes par rapport aux for\êts d\égrad\ée et replant\ée. Les esp\èces allog\ènes \étaient pr\ésentes dans tous les types de for\êt \à l\’exception de la for\êt primaire. La pr\ésence de ces esp\èces n\’\était pas li\ée aux caract\éristiques de la v\ég\étation. En revanche, l\’occurrence des esp\èces indig\ènes \était associ\ée \à des conditions qui sont caract\éristiques des for\êts matures, par exemple une couche de feuilles \épaisse et une couverture foliaire dense. L\’analyse de r\égression logistique a r\év\él\é une valeur seuil pour la hauteur de la couche de feuilles mortes. Au-del\à de ce seuil, il est probable que les millepattes indig\ènes soient pr\ésents. L\’\étude a montr\é que les millepattes indig\ènes sont impact\és par la d\éforestation et qu\’ils ne sont pas facilement restaur\és m\ême si la restauration semble permettre \à la for\êt de se rapprocher de son \état initial.

Two new species of Plusioglyphiulus are described from southern Cambodia. Plusioglyphiulus biserratus sp. nov. is clearly distinguished from all congeners by the shape of the telopodites of the posterior gonopods which are distinctly serrate laterally and by the anterior gonopods showing only a pair of single, smooth and curved coxosternal processes. Plusioglyphiulus khmer sp. nov. is distinguished by having most crests on the collum being complete and male legs 1 showing long, prominent, one-segmented telopodites, coupled with the oblong-subtrapeziform, membranous, posterior gonopods with a small bifid process at about a third of the telopodite length. Notes on the variation of Plusioglyphiulus boutini Mauri\ès, 1970 are also given, including a colour photograph of fresh, live material. A key to all four species of Plusioglyphiulus currently known to occur in Cambodia is also presented.

Laboulbeniales are highly specialized arthropod-associated fungi. The majority of the almost 2200 known species live on insects, although they also occur on other arthropod hosts. Recently, the number of Laboulbeniales associated with millipedes has increased considerably. Here we describe the first species of a Laboulbeniales fungus, Troglomyces twitteri sp. nov., from an American millipede. The new species was initially discovered on a photo of Cambala annulata (Say, 1821) from Ohio, USA, which had been shared on Twitter. A subsequent microscopic study of Cambala millipedes in museum collections in Denmark and France confirmed the discovery.

A new, giant species of Trachyjulus from a cave in southern Thailand is described, illustrated, and compared to morphologically closely related taxa. This new species, T. magnus sp. nov., is much larger than all other congeners and looks especially similar to the grossly sympatric T. unciger Golovatch, Geoffroy, Mauri\ès \& VandenSpiegel, 2012, which is widespread in southern Thailand. Phylogenetic trees, both rooted and unrooted, based on a concatenated dataset of the COI and 28S genes of nine species of Cambalopsidae (Trachyjulus, Glyphiulus, and Plusioglyphiulus), strongly support the monophyly of Trachyjulus and a clear-cut divergence between T. magnus sp. nov. and T. unciger in revealing very high average p-distances of the COI gene (20.80\–23.62\%).

Twenty caves located in a high altitudinal quartzite area in Brazil were examined for invertebrate richness and composition and in terms of environmental factors that determine community structure. We evaluate how distance, altitude, cave extension, environmental stability, number and size of cave entrances and stream presence can act on species composition and richness. The caves presented a high richness of troglophilic (463 spp.) and troglobitic species (6 spp.) in relation to other siliciclastic caves around the world. The average richness was 39.55 species per cave (sd = 21.87), the quantitative similarity among caves was 41\% and turnover was \βrepl. = 0.769. Araneae (20\% of the sampled species), Diptera (18\%) and Coleoptera (14\%) were the dominant orders regarding species richness. Only twenty percent of the caves were placed out of the confidence interval of the average taxonomic distinctness (∆+); however, the ∆+ decreased with the increase of environmental stability. Cave extension and stream presence were the main factors determining the variation of species composition among caves. Cave extension also influenced species richness variations. Furthermore, the total richness and richness of troglobitic species increased with cave extension. The threats to these habitats further revealed that the fauna is at risk due to tourism, trampling and natural soil erosion that can promote microhabitat alterations. Therefore, quartzite caves also require special attention regarding conservation actions in order to keep their natural biological dynamics.
