No full textRachias iricolor (Mello-Leitão, 1923) comb. nov. Hermacha iricolor Mello-Leitão, 1923: 67. Female holotype from Blumenau, Santa Catarina, Brazil, MNRJ 1366, not located. World Spider Catalog, 2016. Note. Hermacha iricolor Mello-Leitão, 1923 is here transferred to Rachias as the original description mentions the following features: almost glabrous carapace; labium almost as long as wide; maxillae with small area of few basal cuspules, with long and curved setae on ventral side that covering the cuspules (Mello-Leitão, 1923). These features agree those of Rachias, as proposed by Goloboff (1995). The holotype of R. iricolor (Mello-Leitão, 1923) comb. nov. has not been located, and no specimens were found in zoological collections. Three expeditions were carried out by the first author in different altitudinal gradients (150–936 m asl) at the type locality and also by other researchers with pitfall traps (see Lucas et al., 2006: 52). However, no specimens have been collected.Published as part of Indicatti, Rafael P., Chavari, João L., Zucatelli-Júnior, Maurílio, Lucas, Sylvia M. & Brescovit, Antonio D., 2017, Six new species of silk-lined burrow spider genus Stenoterommata Holmberg, 1881 (Araneae, Nemesiidae) from southern Brazil, pp. 435-456 in Zootaxa 4254 (4) on page 451, DOI: 10.11646/zootaxa.4254.4.2, http://zenodo.org/record/55603

Inflorescence one-flowered, axillary, supra-axillary, terminal or leaf-opposed, bracts absent. Flowers with pedicel 4–6 mm long, flower buds 3–6 × 1–3 mm, globose to ovoid to conical with acute apex, covered in trichomes. Sepals completely connate, calyx cupuliform, apex truncate to triangular, 3–6 × 4–7 mm, densely covered in trichomes.

Based on this assessment, its conservation status could be interpreted as Endangered, EN B 2ab(iii), according to IUCN Red List Categories and Criteria (2012), as the populations inhabit very threatened forests.</p> <p> Etymology:— <i>mediterranea</i>, from Latin, <i>medius</i> (middle) plus <i>terra</i> (land), meaning inland, in the middle of the land, remote from the sea (Stearn 1983).</p> <p>Phenology:—Specimens with buds and flowers were gathered from February to April, and with buds and fruits in August and October.</p> <p> Notes:— <i>Hornschuchia mediterranea</i> resembles <i>H. lianarum</i>, from Bahia and northern Minas Gerais (<i>Mello-Silva 3140</i>, SPF, Figure 1E <b>–</b> F), which similarly occurs in inland semideciduous forests. Besides inhabiting similar habitats, the two species share the solitary, internodal flowers with a deeply cup-shaped calyx. Characteristics of <i>H. lianarum</i> that distinguish it from <i>H. mediterranea</i> are the pubescent, ovate to broadly ovate and generally smaller leaf lamina with secondary veins slightly raised on both surfaces, and petals connate and orange-cream in bud. <i>Hornschuchia mediterranea</i> also resembles <i>H. alba</i>. These two species share solitary and internodal flowers, free petals that are white even in bud, and glabrous, shiny leaves. The main differences between the two species lie in floral characters: <i>Hornschuchia mediterranea</i> has a calyx 3 <b>–</b> 6 mm long and 4 <b>–</b> 7 mm in diameter, three to six stamens, and five to eight carpels, while <i>H. alba</i> has a calyx 1 <b>–</b> 3 mm long and 2 <b>–</b> 3 mm in diameter, six stamens, and three carpels. In addition, they inhabit quite different types of Atlantic Forest, compared to the other species of <i>Hornschuchia</i> (e.g. Bertoncello <i>et al.</i> 2011). Apart from these three species, only <i>H. obliqua</i> Maas & Setten in Maas <i>et al.</i> (1988: 260) shows a deeply cup-shaped calyx, but it has numerous flowers on supra-axillary to terminal branched rhipidia, and inhabits tropical moist forests. The variable number of stamens is also a notable attribute of <i>H. mediterranea</i>, as almost all other species of the genus present six stamens, except <i>H. santosii</i> D.M.Johnson in Johnson & Murray (1995: 303), with six to 18 stamens, and <i>H. cauliflora</i> Maas & Setten in Maas <i>et al.</i> (1988: 259), which, like <i>H. mediterranea</i>, shows three or six stamens. Such floral reduction is remarkable within the entire family Annonaceae (Johnson & Murray 1995).</p> <p> Additional specimens examined:— BRAZIL. Bahia: Antônio Cardoso.

Physical and dynamical characterization of (5201) Ferraz-Mello, a possible extinct Jupiter family comet
No full textContext. The subject of asteroids in cometary orbits (ACOs) has been of growing interest lately. These objects have the orbital characteristics typical of comets, but are asteroidal in appearance, i.e., show no signs of a coma at any part of their orbits. At least a fraction of these objects are thought to be comets that have either exhausted all their volatile content or developed a refractory crust that prevents sublimation. In particular, the asteroid ( 5201) Ferraz-Mello has, since its discovery, been suspected to be an extinct Jupiter family comet due to the peculiar nature of its orbit. Aims. The aim of this work is to put constraints on the possible origin of ( 5201) Ferraz-Mello by means of spectroscopic characterization and a study of the dynamics of this asteroid. Methods. We used the SOAR Optical Imager (SOI) to obtain observations of ( 5201) Ferraz-Mello using four SDSS filters. These observations were compared to asteroids listed in the Sloan Moving objects catalog and also to photometry of cometary nuclei, Centaurs, and TNOs. The orbital evolution of ( 5201) Ferraz-Mello and of a sample of asteroids and comets that are close to that object in the a - e plane were simulated using a pure N-body code for 4 000 years forward and 4 000 years backward in time. Results. The reflectance spectrum obtained from its colors in the SDSS system is unusual, with a steep spectral gradient that is comparable to TNOs and Centaurs, but with an increase in the reflectance in the g band that is not common in those populations. A similar behavior is seen in cometary nuclei that were observed in the presence of a faint dust coma. The dynamical results confirm the very chaotic evolution found previously and its dynamical similarity to the chaotic evolution of some comets. The asteroid is situated in the very stochastic layer at the border of the 2/1 resonance, and it has a very short Lyapunov time ( 30 - 40) years. Together, the spectral characteristcs and the dynamical evolution suggest that ( 5201) Ferraz-Mello is a dormant or extinct comet
