Pachycoris torridus (Scopoli) and P. klugii Burmeister are two widespread, colorful and well known neotropical Pachycorinae, with partial sympatry in southern Mexico and Central America. Both species are polychromatic, which is why they each present a long list of synonyms. However, with exception of papers describing their different color morphs, there are surprisingly few works dealing with the morphology and taxonomy of these species. This paper details for the first time the genitalia of both sexes and both species. Although some color patterns are almost identical between these species, P. klugii and P. torridus can be perfectly distinguished with basis on their internal and external genitalia.

Malpighia emarginata Sessé & Mociño ex DC. or West Indian cherry (acerola) is a wild plant originated in southern Mexico, Central America and the northern region of South America. The species was introduced to Brazil about 60 years ago and now the country is the world's biggest producer. Even though the fruits of acerola have high commercial value, as they are an important source of the natural vitamin C, very little chromosome information is available for this species. Previous studies showed that most Malpighia species are diploids, including M. emarginata with 2n = 20. In the present paper, the chromosome number of acerola was confirmed, and for the first time, its karyotype was described, providing the identification of the homologues for the ideogram construction. The acerola chromosomes are small (1.71 to 2.56 µm) and metacentric with the exception of chromosome 2 that is classified as submetacentric. In addition, it is recommended a protocol to produce rooted-plantlets in vitro for mitotic studies that could be also used for micropropagation of acerola.

A New Species

The Neotropics harbors a tremendous diversity of cockroaches yet their evolutionary history is largely unknown. We reconstructed for the first time the phylogeny of the Neotropical genus Xestoblatta Hebard using mitochondrial and nuclear genes from 12 species distributed in Central America and northern South America. Additionally, we conducted a morphological analysis of external characters and male genitalia. In the phylogenetic analysis we recovered the genus Xestoblatta as non-monophyletic, resulting in three unrelated lineages. From the morphological variability described here, we identified three different morphological groups matching the phylogenetic results. The phylogenetic relationships of the three lineages within the Blattellidae were partially resolved. Lineage 1 was nested within a supported clade corresponding to the tribes Blattellini + Symplocini, while lineages 2 and 3 nested within the clade corresponding to the tribe Pseudomopini. Based on our results, we propose to divide Xestoblatta (sensu lato) into three monophyletic genera: Antroxestoblatta gen.n., Sinatablatta gen.n., and Xestoblatta (sensu stricto). We also describe a new species Sinatablatta magdalenensis sp.n. and propose a taxonomic rearrangement for Xestoblatta (sensu lato).

SummaryThere are only a few sequences of ancient magic signs known to us today that have been preserved on multiple artefacts. A previously unnoticed sequence of 17 signs on a gem in the Museum of Fine Arts in Vienna occurs with minor but significant variations on two other gems in the State Museum of Egyptian Art in Munich. The Viennese gem is dated to the 16th century and is documented as a drawing in a 17th century publication. The first Munich gem has been assigned to the Graeco-Roman period. The second gem, which, according to the inventory card of the museum, also belongs to the Graeco-Roman period, is published here for the first time. A comparative study of the three gems and the drawing has lead to a number of new findings, including the re-dating of the Munich gems.

In 1958 Deichmann synonymized Holothuria inornata Semper, 1868 with Holothuria kefersteinii (Selenka, 1867). This nomenclature has been adopted until now. However, some specimens recently collected from the Mexican Pacific matched the original description of H. inornata Semper (1868) whereas others matched the original description by Selenka (1867). A morphological, molecular and ecological study of the specimens was conducted to confirm the identification of these specimens. The morphological characters of our specimens were compared with those contained in the original descriptions and figures of the types of both species. Besides the different color pattern of live specimens of both species, the main differences found are the presence of straight distally perforated rods in the dorsal papillae, and the presence of Holothuriophilus trapeziformis Nauck, 1880 in the cloaca of H. inornata, versus the absence of these kind of rods in the dorsal papillae, and the absence of symbionts in the cloaca in H. kefersteinii. The species identified by Deichmann (1958) as H. kefersteinii is, in fact H. inornata. Both species might have been confused because the morphology of preserved specimens is very similar and the presence of the straight rods in papillae might have been overlooked during identification. A more thorough review of the ossicles from the specimens, together with the comparison of ossicles from the type specimens, has allowed the resurrection of long-forgotten species, H. inornata

Purpose In recent years, cities have been facing economic, social and environmental crises that need to be prevented and dealt with. The new subject that has been brought up to improve city resistance to crises is urban resilience. The purpose of this study is to compare the resilience of Tehran and Mashhad to identify the strengths and weaknesses of these two cities for better planning in critical situations. Design/methodology/approach The research methodology is a comparative survey. The importance of the subject was manifested through a literature review. A questionnaire is designed using “the Rockefeller Foundation and ARUP’s model” and the Delphi method for testing 21 research hypotheses to evaluate resilience in the two cities (12 Delphi questionnaires and 232 urban resilience questionnaires). The data is analyzed using independent samples t-test by SPSS software. Findings The results show that both the cities are weak in terms of resilience indicators and sub-indicators, but Mashhad is more resilient than Tehran. Originality/value This paper compares urban resilience in Iran for the first time through a comparative study between two metropolises in the country. The Delphi method also is used for the first time (in Iranian case studies) to obtain the dimensions of urban resilience. By comparing the two cities, we can better understand their strengths and weaknesses.
