A New Species

Abstract—A new species of Eugenia from the Atlantic forest of Brazil is described and illustrated. Eugenia flavicarpa is restricted to the Floresta de Tabuleiro (lowland forests) of Espírito Santo state and is nested in Eugenia subg. Pseudeugenia. Considering all other species of the subgenus that occur in forest vegetation types of the Atlantic forest phytogeographic domain, Eugenia flavicarpa can be distinguished mainly by the combination of smooth leaves with indumentum on both surfaces, with two marginal veins, usually ramiflorous inflorescences, pedicels 4.5‐9.7 mm long, flower buds 3.5‐4 mm in diameter, and by the calyx lobes that are 2‐3 mm long with rounded to obtuse apices. Morphological analyses were performed to explore the significance of quantitative diagnostic features between the new species and the closely related species, Eugenia farneyi. Notes on the habitat, distribution, phenology, and conservation status of Eugenia flavicarpa are provided, as well as a key for all species of Eugenia subg. Pseudeugenia from forest vegetation of the Atlantic forest phytogeographic domain.

Common Group

The nematode diversity in soil and litter was investigated on Mount Hamiguitan, the Philippines, along four eco-habitats from elevations of 75-1600 m a.s.l. A total of 155 and 467 nematodes were identified to 39 and 62 genera from litter and soil, respectively. The nematode assemblages and diversity did not show any relation to eco-habitat or elevation. Bacterivorous nematodes were the most common group (37.5%). Acrobeloides was most abundant from the soil and Aphelenchoides from the litter. Bicirronema hamiguitanense n. sp. is herein described based on morphology, morphometrics and molecular data. The new species has the following diagnostic features: a wide lateral field one-fifth of its body diam. with four incisures forming two ornamented ridges; gubernaculum with proximal thickening; spicules (35-38 μm) and gubernaculum (18-20 μm) longer than B. caledoniense; and with 37 molecular autapomorphies supporting its new species status. The phylogenetic position of the new species within Cephalobomorpha is discussed.

They placed the new genus in the Paussine tribe Metriini, and compared it to the Nearctic genus Metrius Eschscholtz, 1829. Deuve (2020) described a second species S. jaroslavi Deuve, 2020 from Chongqing province.

A New Species

Pseudolebinthus is an intriguing genus of the tribe Xenogryllini with a distribtuion restricted to southeast Africa and characterized by unique morphological features such as asymmetrical male forewings and harp veins shaped as elongated balloons. It is sister group to the widely distributed genus Xenogryllus and has been known by two species, P. africanus Robillard, 2006 and P. whellani Robillard, 2006. The genus was initially diagnosed based exclusively on male morphological features. In this study, we add a new species to the genus, P. gorochovi Robillard sp. nov. and revise the diagnostic features using both male and female characters. We also update identification keys for the species of the genus.

Phylogenetic Studies

The Atlantic Rainforest is a hotspot of biodiversity, housing several endemic species. Environmental stasis through broad time scales, vast latitudinal extension and landscape heterogeneity are thought to contribute in explaining the greater species richness of this biome. Unfortunately, it is threatened mainly due to anthropic-driven habitat loss. Ectotherms of low-mobility, such as tropical, small soft-bodied railroad-worms, may be especially threatened by anthropogenic climate changes. Many of such species have narrow climatic niches and therefore might become extinct before we know them. Here we describe a new genus endemic of the Atlantic Rainforest mountain ranges, and five spatially disjunct new species. Akamboja gen. nov. is unique by its ten-segmented antenna, IV to VIII with two short symmetrical branches, branches of antennomere IX fused in a singular flabellum, slightly depressed medially; elytron short, surpassing the second to fourth abdominal segment (depending on species); first tarsomere of anterior leg with a ventral comb; claws with six long and asymmetrical teeth; aedeagus with patch of bristles at paramere apex. We provide a key to species as well as illustrations for the diagnostic features. We highlight that Akamboja cleidae sp. nov., as defined here, has a disjunct distribution and its populations are surrounded by an unsuitable environmental matrix, thus are probably reproductively isolated. Future phylogenetic studies should address the evolutionary history and delimitation of this taxon. We also provide a key to genera of Mastinocerinae with ten antennomeres, including Akamboja gen. nov.
