Morphological Differences

<p>The genus <em>Lepidochitona</em> (Gray 1821) contains relatively small chitons with a distinctive girdle, dorsally clothed with non-overlapping calcareous corpuscles. In the Caribbean, it is represented by four species: <em>L. liozonis</em> (Dall, &amp; Simpson, 1901), <em>L. rosea</em> Kaas, 1972, <em>L. rufoi</em> García-Ríos, 2010 and <em>L. bullocki</em> García-Ríos, 2011. A rutinary morphological inspection of 10 specimens of a <em>Lepidochitona</em> species from the Florida Keys was concordant with <em>L. liozonis </em>(the only species of the genus informed for Florida). They did not show many morphological differences that could justify its separation from the specimens from Puerto Rico (the type locality). However, the comparison of sequences of the mitochondrial gene coding for cytochrome oxidase I (COI) of <em>L. liozonis </em>from Puerto Rico and the Florida specimens showed a divergence of 14%. This divergence is incompatible with a reproductively connected species. In addition to their genetic differences, the new species differs from <em>L</em>. <em>liozonis</em> in having bigger size, longer marginal spicules and a postmucronal slope very concave.</p>

Most mitochondrial genes are transcribed as a single large transcript from the heavy strand of mitochondrial DNA, and are subsequently processed into the proximal mitochondrial (mt) 12 S and 16 S rRNAs, and the more distal tRNAs and mRNAs. We have shown that in intestinal epithelial biopsies the steady-state levels of mt 12 S and 16 S rRNA are an order of magnitude greater than those of mt mRNAs. Fractionation of rat small intestinal epithelial cells on the basis of their maturity has shown that the greatest ratios of 12 S mt rRNA/cytochrome b mt mRNA or 12 S mt rRNA/cytochrome oxidase I mt mRNA are found in the surface mature enterocytes, with a progressive decrease towards the crypt immature enteroblasts. Cytochrome b and cytochrome oxidase I mt mRNA levels are relatively uniform along the crypt-villus axis, but fractionation experiments showed increased levels in the crypt base. The levels of human mitochondrial transcription factor A are also greater in immature crypt enteroblasts compared with mature villus enterocytes. These results show that the relative levels of mt rRNA and mRNA are distinctly regulated in intestinal epithelial cells according to the crypt-villus position and differentiation status of the cells, and that there are higher mt mRNA and mt TFA levels in the crypts, consistent with increased transcriptional activity during mitochondrial biogenesis in the immature enteroblasts.

  The newly described species, Ziziphus budhensis was confirmed as Chinese Jujuba, Z. xiangchengensis on the basis of their DNA analyses. Z. budhensis was explained as a new species on the basis of some morphological differences in 2015. In the Year 2016, the DNA samples were collected from the type locality of Nepal, and the molecular analyses were carried out. The type specimens and the other available images from the different herbariums were examined. Besides, the protologue and the type images were studied carefully. The result showed that though there were some differences in the habit and the habitat of the plant, the previously described new species, Z. budhensis was found to be same as the Chinese species, Z. xiangchengensis. This study also showed the importance of the molecular work of Z. budhensis and confirmed it morphologically distinct although it was very close to the Chinese species.Banko Janakari, Vol. 27, No. 1, page: 55-59

Nine new species of Duplominona and one new Pseudominona (Platyhelminthes, Proseriata, Monocelididae) are described from the Caribbean coast of Panama and from Puerto Rico.                Duplominona aduncospina n. sp.; D. terdigitata n. sp.; D. pusilla n. sp.; D. bocasana n. sp. (from Panama) and D. dissimilispina n. sp.; D. chicomendesi n. sp.; D. macrocirrus n. sp.; D. diademata n. sp.; D. puertoricana n. sp. (from Puerto Rico) can be distinguished from the numerous congeneric species based on fine details of the sclerotized structures of the copulatory organ. Duplominona aduncospina n. sp. is characterised by a cirrus provided with 3–4 rows of recurve spines, 2–3 μm long. D. terdigitata n. sp. shows a tripartite tail, and needle-shaped cirrus spines, 1.5–9 μm long. Cirrus spines of D. pusilla n. sp. are scale-like, 1.5–3 μm long. D. bocasana n. sp. has triangular spines, 1.5–6 μm long. D. dissimilispina n. sp. has needle-shaped spines, 3.5–15 μm long. D. chicomendesi n. sp. has a small cirrus, with few, strongly curved spines, 2–7.5 μm long. D. macrocirrus n. sp. has a large cirrus, provided with spines 3–9 μm long, with the longest spines placed medially. D. diademata n. sp. has a cirrus with two separate spiny areas, with spines 7–13 μm long. D. puertoricana n. sp. has a very long cirrus, with poorly sclerotised proximal spines, and distal spines to 6 μm long. A taxonomic key of the genus Duplominona is provided. Pseudominona cancan n. sp. from Panama differs from P. dactylifera from Bermuda, the only species known in the genus so far, for its shorter cirrus and fewer, triangular spines 3–5 μm long, and for the position of the vagina, close to mouth. A specimen attributed to P. dactylifera collected in Puerto Rico is described. Distribution of the new species suggests a complete separation of Panamanian and Puerto Rican proseriate fauna, confirming previous reports of restricted ranges and high endemicity of mesopsammic Platyhelminthes.

Pseudonereis gallapagensis Kinberg, 1865 and P. variegata (Grube & Kröyer in Grube, 1858) are the only two species of this genus commonly recorded along Atlantic American coasts, but their type localities are in the Eastern Pacific, and their morphology differs. Two new Pseudonereis species are described from Eastern Mexico: P. brunnea sp. n. from the Gulf of Mexico, and P. citrina sp. n. from the Caribbean Sea, previously confused with P. gallapagensis. In order to facilitate comparisons, descriptions based on specimens from near the type locality for P. gallapagensis (Peru and Ecuador), and topotypes for P. variegata (Valparaiso, Chile), are included. Based on these comparisons and current descriptions, the synonymies of Nereis ferox Hansen, 1882 described from Brazil with P. variegata, and of Pseudonereis formosa Kinberg, 1865 described from Hawaii with P. gallapagensis, are rejected. Consequently, both are regarded as distinct species and revised diagnoses are provided for them. The record of P. ferox from the Gulf of Guinea proved to be an undescribed species, and is herein described as P. fauveli sp. n. The number of paragnath rows in nereidid pharynx areas VII–VIII has been interpreted in several ways, leading to confusion; an alternative method to determine the number of bands and rows is proposed. The midventral region, the division of areas VII–VIII in furrow and ridge regions, and the description of the arrangement based on the pattern of paragnaths in such regions, are proposed. Further, the terms shield-shaped and pointed (P-bars) bars are redefined, and a new term, crescent-shaped bars, is proposed for paragnaths in the areas VI in some Pseudonereis and Perinereis species. A key for all Pseudonereis species is also included.

The new Neotropical treehopper genera Smergotomia, based on S. clairae, new species, from Ecuador, and Braxtonota, based on B. enigmata, new species, from Puerto Rico are described and illustrated. Despite lacking a posterior pronotal process, Smergotomia appears to be most closely related to Smerdalea Fowler based on the forewing venation and male genitalia, but the subfamily and tribal placement of these two genera is uncertain. Braxtonota appears to be related to the two membracid tribes that are endemic to the Caribbean, but lacks the extra hind femoral cucullate setae diagnostic for Monobelini and the large teeth on the second valvulae diagnostic for Nessorhinini. It is provisionally placed in Monobelini. Smerdalea veracruzensis, new species from Mexico, with a pronotum considerably less ornate than its congeners, is also described and illustrated and a key to species of Smerdalea is provided.

There are 23 species of Myrsidea recognized from passerine thraupid hosts. Five new species parasitic on members of this avian family are described. They and their type hosts are Myrsidea rozsai ex the Thick-billed Euphonia, Euphonia laniirostris d'Orbigny & Lafresnaye, M. cruickshanki ex the Carmiol's Tanager, Chlorothraupis carmioli (Lawrence), M. patersoni ex the Grey-headed Tanager, Eucometis penicillata (Spix), M. pagei ex the Crimson-backed Tanager, Ramphocelus dimidiatus Lafresnaye, and M. valimi ex the Tawny-capped Euphonia, Euphonia anneae Cassin. The first species is placed in the bonariensis species group, while the remaining four are placed in the fusca species group. Sequences of a portion of the mitochondrial cytochrome oxidase I (COI) gene were compared to other species of Myrsidea and were highly divergent.
