ABSTRACT Collections of mosquitoes were conducted for the surveillance of species of medical importance in the state of Morelos, Mexico, in June 2017. Species collected included Mansonia (Mansonia) dyari, which was identified using morphological characters and cytochrome c oxidase I DNA barcoding. Although 3 species of genus Mansonia have been previously reported in Mexico, this is the 1st confirmed record of Ma. dyari in Morelos State, where no Mansonia species had been recorded. Historical records of Ma. dyari and Ma. indubitans in Mexico were reviewed. Therefore, this record increases the number of mosquito species occurring in Morelos to 46. The specimens collected in this study were deposited in the Culicidae collection of the Universidad Autónoma Agraria Antonio Narro, Unidad Laguna.

ABSTRACT Theobald first described Culex nigripalpus in 1901 from St. Lucia Island of the Lesser Antilles. It is a Neotropical mosquito species that is documented throughout Central and South America, the Caribbean, and the southeastern USA. Reports within the last 3 decades show the species has expanded its range farther into North America and is not only being discovered sporadically but appears to be establishing itself in several states, of which data are underreported and difficult to find. Five female specimens were collected—4 on October 13 and 1 on December 6, 2017—at 3 separate sites in the city of Suffolk, VA—2 in a BG-Sentinel 2® trap, 3 in Centers for Disease Control and Prevention light traps—during routine mosquito surveillance; subsequent collections were made in 2019 and 2020. These findings represent the 1st record of Cx. nigripalpus in the state of Virginia and the most northeastern records in the USA. An updated mosquito species checklist for the state of Virginia is provided. Additionally, this report serves to update the records of North Carolina to 28 total counties reporting Cx. nigripalpus. These new records, along with other reports and published studies, show this species now documented in 201 jurisdictions in 16 states of the USA. As recent literature on this species is scarce, we provide a review of the bionomics, defining morphological characters, and an updated US distribution map.

Banyaknya spesies invertebrata laut yang memiliki kemiripan morfologi menyebabkan kesalahan identifikasi sangat mungkin terjadi. Identifikasi spesies secara molekuler sangat diperlukan dalam mempelajari taksonomi yang akurat. Penelitian ini bertujuan untuk menentukan identitas invertebrata laut dari Perairan Papua dengan teknik DNA barcoding menggunakan marka gen COI (Cytochrome c oxidase I). Penelitian mengidentifikasi 29 individu invertebrata laut, yang terdiri dari teripang (6 sampel), lobster (6 sampel), gurita (6 sampel), chiton (5 sampel), dan bulu babi (6 sampel). Metode identifikasi molekuler terdiri dari isolasi DNA, PCR fragmen gen COI, sekuensing, dan analisis sekuens DNA menggunakan software bioinformatika.Hasil penelitian ini menunjukkan bahwa teripang merupakan spesies Bohadschia marmorata, lobser merupakan spesies Panulirus versicolor, gurita merupakan spesies Octopus cyanea, chiton merupakan spesies Ischnochiton australis, dan bulu babi merupakan spesies Tripneustes gratilla,  berdasarkan analisis BLAST dan Boldsystem. Dengan tingkat kemiripan sampel dan rujukan dalam kisaran 84.58 sampai 100.00%. Indeks disparitas, jarak genetik dan pohon filogenetik mendukung hasil ini.

This paper reports four new species of the primitively segmented spider genus Songthela from Chongqing Municipality, China, based on morphological characters of both males and females: S. jinyun sp. nov., S. longbao sp. nov., S. serriformis sp. nov. and S. wangerbao sp. nov. We also provide the GenBank accession codes of mitochondrial DNA barcode gene, cytochrome c oxidase subunit I (COI), for the holotype of four new species for future identification.

A new record of Plectropomus pessuliferus (Serranidae: Epinephelinae) wasdocumented based on morphological characters and DNA barcoding. The species was collectedduring a regular survey for making an inventory of reef associated fishes in Saint Martin`sIsland, Bangladesh. This is the first report of roving coral grouper from the marine waters ofBangladesh validated by morpho-meristic analysis and DNA barcoding. This is also the firstreport from the northern Bay of Bengal.
