Three New Species

Thailand is today the richest country for the genus Troglopedetes Joseph, 1872, with 17 species described from the country. In this study three troglomorphic new species are described from caves in the western region. They are T. spectabilissp. nov. and T. rungsimaesp. nov. from Kanchanaburi province and T. takensissp. nov., from Tak province. The three new species share elongated antennae and have the same number of central mac on Th. III and Abd. IV. However, they differ from one another by the combination of: presence of eyes, antennal length, claw morphology, central head macrochaetotaxy and internal row of dental spines. Troglopedetes spectabilissp. nov. is remarkably different from its congeners by its extreme long appendages, especially the antennae (ratio antenna: head = 5.5). In the second part of the paper the arrangment of antennal chaetotaxy and the diversity of its phaneres is analyzed in the three new species, homologized and compared with those of two other species described from Thailand (T. meridionalis and T. kae). A total of 22 types of chaetae have now been recognized among the species. A new type of S-chaetae for the genus was discovered in this study. There are 5 types of ordinary chaetae, 15 types of S-chaetae, the subapical organite of Ant. IV and scales. A total of 1,107 to 2,183 antennal chaetae on each side were observed, which includes 308–485 S-chaetae, 687–1,402 ordinary chaetae, 72–295 scales and a subapical organite.

Two unreported genera and their included species of the shore-fly tribe Scatellini Wirth and Stone that occur in the New Zealand subregion are reviewed. One genus, Haloscatella Mathis, is represented by three species in the subregion and Limnellia Malloch by two. Three of the species, all in the genus Haloscatella, are new (type locality in parenthesis): H. balioptera (New Zealand. Chatham Island: Tennants Lake (43 49.4'S, 176 34'W)), H. karekare (New Zealand. North Island. AK: Karekare (37 00.2'S, 174 28.8'E)), and H. harrisoni (New Zealand. Bounty Islands: Proclamation Island). The fourth and fifth species are in the genus Limnellia: L. abbreviata (Harrison), new combination (originally described in Scatella), was described from specimens collected on Snares Islands, and L. maculipennis Malloch was originally described from a female collected in Sydney, Australia, and is represented by two females from North Island (near Auckland and Hamilton) and a female from South Island (Christchurch). In addition to describing the new species and to facilitate their identification, the tribe and genera are diagnosed, and a key is provided to the known genera of Scatellini from the New Zealand subregion.

A New Species

Piriqueta pampeana, a new species of Turneraceae, is described and illustrated here. The species occurs in the municipalities of Alegrete, Maçambará, Manoel Viana and São Francisco de Assis, in the western region of Rio Grande do Sul state, Brazil. It resembles Piriqueta suborbicularis and Piriqueta taubatensis, but can be distinguished by the presence of a pair of discoid basilaminar nectaries, a pair of petiolar nectaries and small nectaries distributed along the leaf margin, sepals with acute apex and a yellow spot at the base of the petals. Due to the intense environmental degradation of  its habitat, and according to IUCN guidelines, we ranked the species as “Endangered” (EN).

Three New Species

The ‘acantherpestes’ group of dragon millipedes, formerly placed in the genus Desmoxytes Chamberlin, 1923, is revised and assigned to the new genus Nagaxytes Srisonchai, Enghoff & Panha gen. nov. Desmoxytes acantherpestes Golovatch & Enghoff, 1994 is the type species of the new genus and is redescribed as N. acantherpestes (Golovatch & Enghoff, 1994) gen. et comb. nov. Three new species are described from Thailand: N. erecta Srisonchai, Enghoff & Panha gen. et sp. nov. and N. gracilis Srisonchai, Enghoff & Panha gen. et sp. nov. from Kanchanaburi Province, and N. spatula Srisonchai, Enghoff & Panha gen. et sp. nov. from Tak Province. All new species are endemic to western Thailand and all are restricted to limestone habitats. Complete illustrations of external morphological characters, an identification key, and a distribution map are provided.

Passalus Fabricius, 1792 is the largest genus of Passalidae and presents great diversity in South America, mainly in the Amazon region. Currently this complex and heterogeneous genus is subdivided into three subgenera: P. (Pertinax) Kaup, 1869, P. (Mitrorhinus) Kaup, 1871, and P. (Passalus). Herein, two new species of Passalus from the western region of the Brazilian Amazon, a diverse but poorly studied area, are described and illustrated. The new species Passalus (Pertinax) deuterocerus sp. nov. and Passalus (Passalus) cleidecostae sp. nov. are compared with similar species occurring in nearby regions. Also, the diagnostic characters used to define the subgenera and sections of Passalus are summarized.

A new species of Calvatia is described from a semideciduous seasonal forest fragment in the western region of Paraná State, southern Brazil. Calvatia guzmanii is proposed as new based on the combination of dark brown and spiny to velvety exoperidium, prominent subgleba and echinulate-reticulate basidiospores with a short pedicel. A comparison with morphologically similar Calvatia species is giv

Three species of Panaeolus were collected in the western region of Paraná State, South Brazil. Panaeolus sylvaticus is proposed as a new species, based on macro- and micromorphological features and substrate (rotten wood and litter). Panaeolus antillarum and P. papilionaceus var. parvisporus, two coprophilous and widely distributed species, are also reported. All species are illustrated and discussed in detail, regarding their taxonomy, ecology and distribution. A key to the known species of Panaeolus from Paraná State is presented.

Three New Species

Abstract The fauna of bristletails of the genus Lepismachilis Verhoeff, 1910 in Montenegro and Serbia includes only one species L. (Berlesilis) targionii (Grassi, 1887) with 2 + 2 eversible vesicles on abdominal urocoxites II–VI. Three new species of this genus are described: L. (Lepismachilis) prijepolja sp. nov., L. (Lepismachilis) limensa sp. nov. from Serbia, and L. (Lepismachilis) alexandrae sp. nov. from Montenegro. All described new species belong to the species group of the subgenus Lepismachilis s. str. with 2 + 2 eversible vesicles on abdominal urocoxites II–V. Lepismachilis prijepolja sp. nov. differs from L. y-signata Kratochvíl, 1945 and L. notata Stach, 1919 by the color, drawings and ratios of the compound eyes; ratios of sensory field on fore femur of male, number of divisions of ovipositor. Lepismachilis limensa sp. nov. differs from L. hauseri Bitsch, 1974 and L. abchasica Kaplin, 2017 by ratios of paired ocelli, sensory field on fore femur of male; ratios and chaetotaxy of maxillary and labial palps. Lepismachilis alexandrae sp. nov. differs from L. abchasica by the drawings of the compound eyes; ratios of paired ocelli, sensory field on fore femur of male; number of divisions of the parameres and gonapophyses. A list of the Machilidae occurring in Balkan Peninsula is also provided.
