The setal arrangement on the dactyl and propodus of pereopods 1 and 2, defined here as the feeding apparatus, of 3 species of cave shrimps of the genus Typhlatya (T. mitchelli, T. pearsei, T. dzilamensis) from the Yucatán Peninsula was studied using SEM micrographs. The setae were classified according to their morphology and position in the propodus and dactyl resulting in 6 main types. The 3 Typhlatya species differed slightly in the number of each type of setae and showed some morphological variations, especially in the central setae. A comparison of the setal arrangement of Typhlatya spp. with that of the epigean Potimirim mexicana and P. glabra, showed important differences probably driven by the specialization to specific habitats.
本文用扫描电镜研究了Yucatán半岛3种洞虾(T. mitchelli, T. pearsei, T. dzilamensis)的足足目1和足足目2(此处定义为摄食器)的指趾和拟足的设置。根据刚毛在足趾和趾趾的形态和位置，将其划分为6个主要类型。3种伤寒菌在各类型刚毛数量上略有差异，在形态上也有一定的差异，特别是在中央刚毛上。对伤寒菌的设置与上世的Potimirim mexicana和P. glabra的设置进行了比较，发现可能是由于对特定生境的特化所致。

La papa es uno de los cultivos alimenticios más importantes para el Cusco, Perú. Sin embargo, es afectado por un gran número de plagas que pueden reducir grandemente su rendimiento. Entre los problemas más importantes se encuentran los “gorgojos” (Coleoptera: Curculionidae) que, a pesar de numerosos estudios, aún no han sido identificados adecuadamente. El presente proyecto de investigación se orientó a identificar las especies de gorgojos asociados con el cultivo de papa. Se estudió el material depositado en la Colección Entomológica de la Universidad Nacional de San Antonio Abad del Cusco. Se logró identificar a 20 especies, pertenecientes a las subfamilias Cryptorhynchinae: Maemactes vestitus Kirsch, 1875; Cyclominae: Adioristidius costulatus (Hustache, 1938), A. manu Morrone, 1994, Amathynetoides nitidiventris, Antarctobius sp., Falklandiopsis magellanica (Morrone, 1992), Hyperoides victus (Germain, 1896), Nacodius alectrus Morrrone, 1994, Puranius obrienorum Morrone, 1994 y Telurus sp.; y Entiminae: Cylydrorhinus villosulus (Hustache, 1926), C. elongatus (Kuschel, 1949), Cylydrorhinus sp., Amitrus mundus (Erichson, 1834), A. nitens Voss, 1947, Premnotrypes solaniperda (Kuschel, 1956), P. latithorax (Pierce, 1914), P. pusillus (Kuschel, 1956), Rhinotrypes grossepunctatus Kuschel, 1956 y R. laevigatus Kuschel, 1956.

Se colectaron 9 especímenes de Paronatrema guillerminae n. sp. de las branquias del tiburón azul Prionace glauca (Linnaeus) durante la captura por pesca artesanal en la localidad de Punta Belcher (bahía Magdalena), Baja California Sur, México. Se propone a P. guillerminae n. sp. como una nueva especie dentro del género Paronatrema (Dollfus), por presentar características distintivas de otras especies cogenéricas, tales como el tamaño del cuerpo (más grande que las restantes), tegumento con extensiones en forma de escamas, forma del ovario (redondeado) y el número de testículos (más de 200 testículos). La nueva especie se describe en este trabajo.

Less than 1% of the literature on El Salvador’s biodiversity is about terrestrial invertebrates, which limits our knowledge of this group’s diversity, richness, and distribution in the territory. Scarabaeoidea are megadiverse in multiple ecosystems and perform many functions. This work aims to catalog the Scarabaeoidea in El Salvador. We conducted an exhaustive review of published literature and reviewed numerous entomological collections with relevant material. Maps were constructed to visualize the known distribution of each species in the country. There are 295 scarab beetle species (including 19 new country records) representing 106 genera in 7 families in El Salvador. Six precinctive species are known. Twenty-two species are discarded as occurring in El Salvador, either because they are not valid species or because of misidentifications or dubious records. This work is the first approach to knowing the Scarabaeoidea in El Salvador, a territory that is usually considered of no importance for the conservation of regional biodiversity due to its small area, high rate of deforestation, and overpopulation. The results of this work reinforce the need for biological prospecting in the territory to know, conserve, and protect the remaining biodiversity.

To study synanthropic plants (weeds), weeds need to be separated from non-weeds, a difficult task due to the existing gradient in nature. A representative family of the Mexican flora (Asteraceae) and a state very rich in species (Michoacán) are used as a model for this task and additional analyses. A total of 357 weeds are listed based on a critical review of specimens and bibliographic information, as well as defined criteria. In addition, tribes, growth forms, and geographic similarities with other states are examined for endemic, more widespread native, and introduced weeds. The main difficulty in differentiating weeds from non-weeds was the lack of accurate habitat information on herbarium labels. Most species grew in both disturbed and natural environments. Nearly half were endemic to the country, with only 4% introduced. The major Asteraceae tribes had relatively similar proportions of weeds, but exotics were concentrated in the tribe Cichorieae. Floristic similarities were mainly towards south-central Mexico. Most species were herbs and less than half annuals. We contribute to the delimitation and understanding of synanthropic species.

Las luciérnagas (Coleoptera: Lampyridae) tienen importancia turístico-cultural debido a su bioluminiscencia. En el “Santuario de las Luciérnagas” (Nanacamilpa, Tlaxcala) habitan poblaciones de Photinus palaciosi. Anualmente, este sitio es visitado por una gran cantidad de turistas. Sin embargo, faltan estudios ecológicos sobre la biología de la especie y factores abióticos que afectan la abundancia de sus poblaciones. Se comparó la abundancia de adultos en 3 tipos de vegetación y se analizó la relación de factores abióticos sobre la abundancia local de esta especie, se registró talla promedio y proporción de sexos. Se hicieron muestreos en bosque de encino, pino y mixto (pino-encino), con redes aéreas. Se recolectaron 397 especímenes (386 machos y 11 hembras). La temperatura, humedad, punto de rocío y el índice de calor, afectaron la abundancia de las poblaciones de la especie. No hubo un efecto de la vegetación sobre la abundancia y el tamaño corporal. La proporción sexual mostró un sesgo hacia los machos y diferencias entre el bosque de encino (frecuencia menor a la esperada) y el mixto presentó un patrón contrario. Es necesario seguir con estudios a largo plazo para comprender el estado de las poblaciones y proponer medidas de conservación.

Sceloporus aeneus y Sceloporus bicanthalis son especies de reciente evolución, similares en morfología e historia de vida, pero difieren en el modo reproductor y número de escamas cantales. Sin embargo, este último carácter es altamente variable y es el único, a una escala morfológica, que se ha usado hasta la fecha para diferenciarlas. En el presente trabajo se analizó el grado de variación morfológica de las escamas cefálicas, mediante morfometría geométrica y estadística multivariada, para determinar si el uso de estos métodos permite separar con mayor precisión ambas especies. Para ello, se utilizaron fotografías digitales de S. aeneus y S. bicanthalis y se colocaron marcas en escamas de la región dorsal, ventral y lateral de la cabeza. Los resultados muestran diferencias significativas en la forma de las escamas entre ambas especies para todas las vistas, de manera que cada especie presenta un morfotipo definido en lo que respecta a la escutelación del cráneo. El análisis sugiere que ambas especies pueden ser identificadas mediante variaciones en la forma de las escamas parietal e interparietal y no por el número de escamas cantales.

The study of planktonic mollusks is a relevant element to understand the dynamics of the benthic communities under present and future environmental conditions. We present the description of the biodiversity of planktonic gastropods at 2 sampling sites on the Pacific coast of the Baja California Peninsula, Mexico. Organisms collected from plankton tows at 2 locations (Cabo Tosco, n = 89 and La Bocana, n = 213) were sequenced for a portion of the 18S rDNA gene. High diversity was registered, with 71 Molecular Operational Taxonomic Units (MOTUs), which contrasts with the low phenotypic diversity of stereoscopic images. Differences in community composition between and within sampling sites indicate that planktonic gastropod distribution is not random but probably modulated by micro-environmental processes such as currents or biological events. The presence of non-gastropod sequences within some shells (n = 6) suggests their use as carriers of eggs or larvae of other taxa.

The Mexican Caribbean Sea is the longest section of the Mesoamerican Caribbean Sea, with 16 protected marine areas. During 2015 and 2016, 2 sampling campaigns in the Puerto Morelos Coral Reef National Park and the Sian Ka’an Biosphere Reserve, Quintana Roo, Mexico, were carried out to determine the biodiversity of benthic amphipods. In addition, the previously documented amphipod data were included to summarize the first checklist of such amphipods along the Mexican Caribbean Sea. The present study found 35 families, 70 genera, and 121 species, of which 41 species had not been previously reported in the Mexican Caribbean Sea, and 5 species represented new records of amphipods from the Caribbean Sea. According to the information summarized in this amphipod’s inventory, both the coral reefs Puerto Morelos and Sian Ka’an, located in the north and central Mexican Caribbean Sea, represented the protected natural areas with the largest amounts of benthic amphipod species thus far.
墨西哥加勒比海是中美洲加勒比海最长的一段，有16个海洋保护区。2015年和2016年，在莫雷洛斯港珊瑚礁国家公园和墨西哥金塔纳罗奥州的Sian Ka 'an生物圈保护区进行了两次采样活动，以确定底栖片脚类动物的生物多样性。此外，还包括以前记录的片脚类动物数据，以总结墨西哥加勒比海沿岸这种片脚类动物的第一个清单。本研究共发现35科70属121种，其中41种为墨西哥加勒比海片脚类新记录，5种为加勒比海片脚类新记录。根据该片脚类动物清单总结的信息，位于墨西哥加勒比海北部和中部的Puerto Morelos珊瑚礁和Sian Ka’an珊瑚礁是迄今为止底栖片脚类动物物种数量最多的自然保护区。

In addition, the previously documented amphipod data were included to summarize the first checklist of such amphipods along the Mexican Caribbean Sea. The present study found 35 families, 70 genera, and 121 species, of which 41 species had not been previously reported in the Mexican Caribbean Sea, and 5 species represented new records of amphipods from the Caribbean Sea. According to the information summarized in this amphipod’s inventory, both the coral reefs Puerto Morelos and Sian Ka’an, located in the north and central Mexican Caribbean Sea, represented the protected natural areas with the largest amounts of benthic amphipod species thus far.","PeriodicalId":49603,"journal":{"name":"Revista Mexicana de Biodiversidad","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49006532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pilotrichella, a genus of epiphytic mosses comprising 6 species and 1 form, is represented in Mexico by P. flexilis(Hedw.) Aongstr., P. flexilis fo. nudiramulosa (Müll. Hal.) B. H. Allen & Magill, P. mauiensis (Sull.) A. Jaeger, and P. reesei B. H. Allen & Magill. The last species is known from a single specimen. The Peruvian P. vermiformis B. H. Allen & Magill is reported here as new to Mexico from Hidalgo, Veracruz, and Oaxaca. In total, 260 specimens deposited at MEXU served to illustrate, map, and discuss the basic morphology of the local taxa.
