We report fluid feeding with a sucking pump in the arthropod class Diplopoda, using a combination of synchrotron tomography, histology, electron microscopy, and three-dimensional reconstructions. Within the head of nine species of the enigmatic Colobognatha, we found a pumping chamber, which acts as positive displacement pump and is notably similar to that of insects, showing even fine structural convergences. The sucking pump of these millipedes works together with protractible mouthparts and externally secreted saliva for the acquisition of liquid food. Fluid feeding is one of the great evolutionary innovations of terrestrial arthropods, and our study suggests that it evolved with similar biomechanical solutions convergent across all major arthropod taxa. While fluid-feeding insects are megadiverse today, it remains unclear why other lineages, such as Colobognatha, are comparably species poor.

Siphonophora hui Jiang et al., 2019, known from the mid-Cretaceous Burmese amber, is the first formally described fossil species of the extant myriapod family Siphonophoridae. Here we re-study this species using confocal laser scanning microscopy (CLSM) on the basis of three new specimens from the same deposit. A comparison between the fossil and extant species of Siphonophora is given and several new morphological details are discussed.

Dans le cadre d’un programme d’inventaire conduit depuis 2011, l'entomofaune de cinq zones naturelles d'intérêt écologique, faunistique et floristique (ZNIEFF) situées dans le centre et l’est de la Martinique (Petites Antilles) a été échantillonnée au titre du programme d’étude 2019. S’est également ajoutée une station témoin en zone rurale agricole, La Broue (Vauclin), dont l’objet est d’étalonner la valeur patrimoniale des ZNIEFF. Des techniques de collecte variées (pièges d'interception Polytrap, piège lumineux, piège Polyvie bleu, pièges aériens, recherche active et mise en émergence) ont été utilisées durant une mission de terrain de 18 jours en avril/mai 2019 puis complétées par une phase de terrain en octobre/novembre 2019 (12 jours) comprenant des techniques complémentaires (en particulier piège Malaise, assiettes colorées et tamisage) et de la recherche active. Au total 2040 données, correspondant à 9 046 spécimens étudiés pour 630 taxons d’arthropodes, dont 577 insectes (espèces ou morpho-espèces) ont été déterminées par un ensemble d’une quinzaine de spécialistes.

Comme en 2017 et 2018, le protocole a mis l’accent sur les Hyménoptères, tout particulièrement les fourmis, avec un spécialiste sur le terrain pendant toute la seconde phase d’inventaire (octobre/novembre).

En forêt hygrophile, les sites de Morne des Olives et Bois Duhautmont présentent un fort intérêt, avec de nombreuses espèces endémiques. Le Morne des Olives (ZNIEFF41) figure même parmi les ZNIEFF les plus riches en espèces déterminantes. On peut notamment citer la présence de Castnia pinchoni Pierre, 2003, Rothschildia erycina luciana Rothschild, 1907 ou encore Mionochroma rufescens (Gahan, 1895).

Les trois sites de forêt xérophile, Rocher Leclerc, Morne Valentin et Pointe La Rose, abritent un nombre moyen d’espèces déterminantes, avec le cortège saproxylique typique des milieux secs et littoraux. Une des observations les plus remarquables est celle d’une deuxième station de la cétoine Madiana brigitteae Ratcliffe & Romé, 2019, genre et espèce endémiques très localisés dans l’état actuel des connaissances.

L’inventaire de la station témoin de La Broue (Vauclin), en zone rurale arborée, a été riche d’enseignements : la zone présente une faune plutôt diversifiée, dont 4 espèces déterminantes ZNIEFF. Cependant, il s’agit d’une faune globalement de milieux ouverts et secondaires et cette zone reste moins intéressante que la majorité des ZNIEFF.

Les déterminations réalisées pour cette étude viendront compléter le référentiel taxonomique des insectes de Martinique (TAXREF) de plusieurs espèces connues d'autres îles ou du continent américain, et non encore signalées de Martinique.

Although most millipedes (Diplopoda) show a biting–chewing feeding mode, representatives of the so‐called Colobognatha (Platydesmida, Polyzoniida, Siphonocryptida, Siphonophorida), with their more or less reduced mouthparts, are assumed to have evolved a suctorial feeding mode, which enables them to exploit food sources like algal film and fungi hyphae. The Platydesmida are viewed as the key taxon for the understanding of mouthpart adaptations in Colobognatha, as their mouthpart elements still closely resemble those of biting–chewing millipedes. Studies of the skeletomuscular system of the Platydesmida are rare, impeding further understanding of the mouthpart evolution in millipedes. To overcome this impediment in the understanding of millipede evolution, we study the internal morphology of the head in specimens from four genera of Platydesmida: Brachycybe lecontii, Dolistenus spp., Gosodesmus claremontus, and Pseudodesmus spp. Although all Platydesmida show similarly structured skeletal elements and accompanying musculature, they are distinct from all other Diplopoda. Their head lacks eyes and organs of Tömösváry, and is pyriform and posteriorly bulging, overlapping the collum. The narrow mandibles are hidden underneath the broad genae. A previously described gnathochilarial postmentum is absent. Muscle attachment sites, such as the transverse mandibular tendon and the median septum, are reduced. The strong modifications of the head capsule, mandibles, and musculature limit the movability of the mandible for biting–chewing motions based on simulations of possible gape angles. Platydesmida likely show a scraping and slurping feeding mode, which is facilitated by the comparably well‐developed pharyngeal dilator muscles. We suggest that the Platydesmida show an intermediate state between the biting–chewing millipedes and the other suctorially feeding Colobognatha.

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' response to tropical forest degradation and their role in reforestation. The present article should rather be regarded as a review of millipedes' 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' 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.

Resumé: Les conséquences de la déforestation globale sont multiples. Pour la plupart des organismes, la déforestation est la cause principale de la destruction des habitats. Les arthropodes qui vivent sur le sol forestier ou dans le feuillage sont ainsi menacés, surtout dans les forêts tropicales. Ces organismes sont pourtant indispensables au maintien de la résilience de la forêt. Dans l’écosystème forestier, les millepattes et autres arthropodes sont très importants pour la mise à disposition de différents services écosystémiques, par exemple pour leur rôle dans le cycle des éléments nutritifs, la formation des sols et la décomposition. Malgré leur importance, peu d’informations sont disponibles sur la réaction des invertébrés suite à la dégradation des forêts et leur rôle dans la reforestation.

Cette étude tient surtout lieu de révision de l’occurrence des millepattes dans les forêts tropicales avec une étude pilote menée à Madagascar, dans la mesure où l'échantillonnage est réduit et que les résultats restent partiels. Cette étude pilote analyse les relations entre les millepattes et les caractéristiques végétales dans les forêts de l’Est de Madagascar, dans la région d’Andasibe. Ces forêts sont très diverses et dix types de forêt ont été considérés, à savoir une forêt récemment dégradée et une forêt dégradée, une forêt dégradée et reboisée avec des espèces arborées indigènes en 2007, 2012 ou 2015, des plantations d’Eucalyptus abandonnées depuis 1930 ou 1909, deux forêts secondaires, une forêt primaire. Dans ces différents types de forêt, les caractéristiques de la végétation ont été enregistrées et des millepattes ont été récoltés à la main. Les espèces de millepattes ont été identifiées et leur occurrence ont été analysées par rapport aux caractéristiques de la végétation. Les vieilles plantations d’Eucalyptus et les forêts secondaire et primaire étaient caractérisées par une couche plus épaisse de feuilles et davantage d’espèces de millepattes indigènes par rapport aux forêts dégradée et replantée. Les espèces allogènes étaient présentes dans tous les types de forêt à l’exception de la forêt primaire. La présence de ces espèces n’était pas liée aux caractéristiques de la végétation. En revanche, l’occurrence des espèces indigènes était associée à des conditions qui sont caractéristiques des forêts matures, par exemple une couche de feuilles épaisse et une couverture foliaire dense. L’analyse de régression logistique a révélé une valeur seuil pour la hauteur de la couche de feuilles mortes. Au-delà de ce seuil, il est probable que les millepattes indigènes soient présents. L’étude a montré que les millepattes indigènes sont impactés par la déforestation et qu’ils ne sont pas facilement restaurés même si la restauration semble permettre à la forêt de se rapprocher de son état initial.

An inventory of the Myriapoda (Diplopoda, Chilopoda, Symphyla) from Cretaceous Burmese amber, Myanmar, is presented, including the oldest and/or first fossil record for numerous orders. For millipedes (Diplopoda) 527 records, including 460 new specimens determined by us, belonging to 13 of 16 recent orders are listed: Polyxenida, Glomeridesmida, Glomerida, Siphonophorida, Polyzoniida, Platydesmida, Siphoniulida, Chordeumatida, Polydesmida, Stemmiulida, Callipodida, Spirostreptida and Spirobolida. For centipedes, 33 records for 4 of the 5 recent orders are listed: Scutigeromorpha, Lithobiomorpha, Scolopendromorpha and Geophilomorpha. For Symphyla, three records for both families, Scutigerellidae and Scolopendrellidae, are listed. The majority of Diplopoda records (30.5%) are Polydesmida. The record of the Polyzoniida includes first instar octopod juveniles. The checklist includes the first fossil representatives known of the Platydesmida, as well as the oldest known fossils of the Polyxenida, Glomeridesmida, Glomerida, Siphonophorida, Polyzoniida, Siphoniulida, Spirostreptida, as well as both Symphyla families. Misidentifications by Zhang (2017) are corrected; while most Chilopoda in that list are correct, almost all Diplopoda are misidentified.

Representatives of 11 genera (Lophoproctus?, Glomeridesmus, Epinannolene, Siphonophora, Siphonotus, Docodesmus, lomus, Lophodesmus?, Psochodesmus, Dasyodontus, and Inodesmus?) are reported from Dominican amber, most of them constituting the first or oldest fossils of their corresponding higher taxa. Extant species of lomus and Inodesmus have not been reported from Hispaniola; a chelodesmid seems more closely related to South American genera than to present-day Caribbean diplopods. Siphonophora hoffmani spec. nov. and S. velezi spec. nov. are described from adults embedded in Dominican amber.

New localities are reported to detail the distributions of the order Siphonophorida and the family Siphonophoridae in the southwestern and southcentral United States, and northern Mexico. The northernmost sites are in Los Angeles County, California; Yavapai County, Arizona; and Coryell County, Texas. The Siphonorhinidae is represented by only one genus and species, Illacme plenipes Cook & loomis, known only from northern San Benito County, California, the northernmost ordinal record. Congeneric starus is confirmed for Siphonacme lyttoni Cook & loomis, in Arizona, and S. pseustes (Chamberlin), in Sonora, Mexico; Californizonium Verhoeff is synonymized under Siphonacme Cook & loomis. Diagnostic illustrations are presented for I. plenipes, S. lyttoni and pseustes, and Siphonophora limitare Loomis and texascolens Chamberlin & Mulaik.

Fossil records of the ancient and less studied millipede order Siphonophorida are rare and only known from Oligocene-Miocene Dominican amber to date. Here, we describe a Mesozoic species of this order, Siphonophora hui sp. nov., based on two well-preserved specimens from mid-Cretaceous Burmese amber. The new species can be placed in the family Siphonophoridae by having mouthparts strongly modified into a long beak, straight antennae, the separation of tergites, pleurites and sternites, leg-like gonopods derived from 9th and 10th leg pairs, and absence of ommatidia. This discovery pushes back the fossil record of Siphonophorida by more than 60 Ma. It also demonstrates that the details of the siphonophorid body plan have remained virtually unchanged for nearly 100 million years. An enigmatic structure on the antennae of the paratype may represent either the ancestral form of the circular sensory pits, or more unlikely, the earliest occurrence of a fungus parasitic or commensal on an arthropod.
