Four new Mexican Parajapyx species are described: P. silvestrii sp. nov. differs from P. adisi Pagés by the presence of one ma macroseta on mesoscutum, metascutum and abdominal scutum I; P. pagesi sp. nov. differs from P. grassianus Silvestri in the arrangement and number of macrosetae on all abdominal scuta; P. brunocondei sp. nov. is characterized by the unique feature of 50 glandular setae on the subcoxal organs and femur with one macroseta; P. yunyanorum sp. nov. differs from P. reymi Pagés by having some reduced macrosetae on the mesoscutum and metascutum and one lp macroseta lacking on abdominal II to VII scuta. A redescription of P. isabellae aztecus Silvestri, 1948 is presented including additional characters not previously reported, such as complete body chaetotaxy and descriptions of leg III, antennae and cercus. An identification key is presented for Mexican species of Parajapyx.

A New Species

A new Mexican species of Spigelia (Loganiaceae), distributed in the states of Guerrero and Michoacán, is here described. The new species can be distinguished from the similar-looking S. humboldtiana by its corolla with innerly purple lobes, inserted stamens above the proximal half of the corolla tube and exserted style. With this contribution, Mexico reaches a total of 20 species, of which 50% are endemic, highlighting this country as a center of diversity for this genus. A dichotomous key for the species recorded in the states of Guerrero and Michoacán is included.

A new species of Robertgurneya Apostolov & Marinov, 1988, with an illustrated record of R. rostrata (Gurney, 1927), an amended genus diagnosis and comments on R. soyeri (Apostolov, 1974) and R. spinulosa (Sars, 1911) (Harpacticoida: Miraciidae)

A New Species

Quarterly sampling campaigns were carried out during year 2019 to study the effects of organic pollution on the diversity and abundance of meiofauna from a polluted coastal system in north-western Mexico. Amongst harpacticoids, the family Miraciidae Dana 1846 was by far the most abundant and diverse, and several new species and the proposal of some new genera of Stenheliinae Brady 1880 and Diosaccinae Sars 1906 will be published elsewhere. Amongst the Diosaccinae, the genus Robertgurneya Apostolov & Marinov 1988 was one of the most abundant. This genus was proposed and diagnosed by Lang (1944, 1948) but after a complex taxonomical history, was made available by Apostolov & Marinov (1988) who proposed an amended diagnosis and designated R. similis similis (Scott A. 1896) as the type species of the genus. Here I propose a new species, Robertgurneya mexicana sp. nov., and give a fully illustrated record of the widely distributed R. rostrata (Gurney 1927). The relationships amongst the species of Robertgurneya are not clear, but the new Mexican species shares with R. falklandiensis (Lang 1936) the elongated inner dimorphic spine on the basis of the male P1. Additionally, a new amended diagnosis for the genus Robertgurneya, as well as the reallocation of R. soyeri (Apostolov 1974) into Typhlamphiascus Lang 1944, and the creation of a new genus, Robertgurneyella gen. nov., for R. spinulosa (Sars 1911) are proposed.

To date, the subgenus Rhomboconnus Franz of Euconnus Thomson was represented by twelve species known to occur in Bolivia, Ecuador, Panama, Peru, and Venezuela. Examination of Neotropical species described by David Sharp and Ludwig Wilhelm Schaufuss revealed that two more species, previously not recognized as members of Rhomboconnus, occur in Guatemala and Brazil: Euconnus cavifrons (L.W. Schaufuss) and E. giraffa Sharp. The latter species was redescribed by Herbert Franz and recorded to occur in Mexico. Franz’s ‘redescription’, however, was based on misidentified specimens. Five new species are described, all known to occur in souther n Mexico: Euconnus (Rhomboconnus) agiraffa sp. n., Euconnus (Rhomboconnus) oaxacanus sp. n., Euconnus (Rhomboconnus) bicarinatus sp. n., Euconnus (Rhomboconnus) cordobanus sp. n., and Euconnus (Rhomboconnus) maya sp. n.

A new species of the genus Xenylla Tullberg, 1869 is described. The new species, Xenylla weinerae sp. nov., from China, resembles X. acauda Gisin, 1947, X. brevicauda Tullberg, 1869, X. caudata Jordana, 1993, X. lesnei Denis, 1935, X. nirae Gama & Oliveira, 1994, X. wandae Queiroz & Mendonça, 2016 and X. vanharteni Weiner et al., 2012 due to unique feature––six thickened cylindrical sensilla on antennal segment IV. X. weinerae sp. nov. having moderately modified chaetotaxy (b h1 h2 q t, head with dorsal setae l1 and l3 subequal, dorsal setae a3 on Abd. IV present) and well-developed furca (mucro separated from the dens, bearing 2 setae) is also similar to some populations of X. obscura Imms, 1912 sensu Thibaud et al. (2004). An identification key to Asian Xenylla species is provided.

A New Species

In this study, we analyzed the morphological affinities of the 24 species of Amphitecna based on detailed morphological studies and multivariate cluster analyses. Our results suggest that the genus Amphitecna includes six morphological groups that can be easily distinguished based on floral and fruits characteristics: A. donnell-smithii group, A. macrophylla group, A. megalophylla group, A. molinae group, A. spathicalyx group, and A. steyermarkii group. A new species from Mexico, Amphitecna fonceti, is described. This new species is clearly differentiated by the predominantly ramiflorous inflorescences bearing multiple flowers per shoot, buds rounded at the apex, large flowers with a transverse fold in the corolla throat, calyx surface pubescent and strongly costate, and fruits elliptic, apiculate at the apex. We discuss the characteristics of each morphological group and their geographical distribution, provide a detailed description of the new species including ethnobotany notes, and propose the re-establishment of the giant-leaved species A. megalophylla.
