The concept of the genus Gaeolaelaps of the mite family Laelapidae is reviewed, based on species descriptions in the literature and the examination of specimens of selected described and undescribed species. A short diagnosis and a description of the genus is presented, showing the range of morphological character states and indicating species that depart from the typical character states. Gaeolaelaps is restored from subgeneric to generic rank. A new species, G. gillespiei n. sp., is described from adult female and male specimens. This species shows promise in the control of fungus gnats and thrips on greenhouse cucumbers in British Columbia, Canada. It is a relative of the well known biocontrol agent Gaeolaelaps (or Hypoaspis) aculeifer, but presents a set of morphological traits that distinguish it from G. aculeifer and other related species. The diversity of soil-dwelling mesostigmatic mites remains poorly explored, and so is their potential for biological control.

Sperchon fuxiensis Zhang, 2017 was published as a new species based on females alone. Two males of Sperchon were found in the same locality during our recent collection. The males resemble S. fuxiensis female in the integument pattern, excretory pore and the palps shape, but the chitinous plates of both dorsum and venter differ greatly. The males were paired with the female of S. fuxiensis using DNA barcoding, revealing unusual sexual dimorphism in the species. Descriptions and illustrations of the male of S. fuxiensis are given in the present study. Species identification based on the full-length DNA barcoding (658bp) of COI in water mites is also discussed.

The perennial species of Trifolium Linnaeus section Involucrarium Hooker are revised. A key to the species, descriptions of species, synonyms, typification, distribution maps, and notes are presented. The following chromosome numbers are reported as new: T. mucronatum Willd. ssp. mucronatum, 2n = 16; T. mucronatum ssp. vaughanae J. M. Gillett, 2n = 16; and T. wormskioldii Lehmann, 2n = 16. The following combinations are made: T. mucronatum Willdenow ssp. lacerum (Greene) J. M. Gillett, T. monanthum A. Gray ssp. parvum (Kellogg) J. M. Gillett, T. monanthum ssp. tenerum (Eastwood) J. M. Gillett, and T. monanthum ssp. grantianum (Heller) J. M. Gillett. A new species, Trifolium siskiyouense J. M. Gillett and a new subspecies, T. mucronatum ssp. vaughanae are described. Taxonomic problems are discussed.

A New Species

Tiger beetles are a popular group of insects amongst amateur naturalists, and are well-represented in museum and private collections. New species descriptions plateaued in the 19th century, but there is a recent resurgence of discoveries as integrative taxonomy methods, guided by molecular systematics, uncover “cryptic” tiger beetle diversity. In this paper, we describe a new species using multiple data types. This new species, Eunota mecocheila Duran and Roman n. sp., is in the tribe Cicindelini, and is described from specimens collected in saline muddy ditches in northern Mexico. This species is closely related to E. circumpicta (LaFerté-Sénectère, 1841), but is separated based on morphological differences, geographic range, and genetic differentiation. Little is known about the biology or distribution of this species and it has only been collected from two sites in the state of Coahuila. Given the location of this new species, and its genetic divergence from its closest relative, E. circumpicta, we discuss the historical biogeography that may have led to isolation and speciation. The male and female dorsal, lateral and frontal habitus and the male aedeagus are shown.

A New Species

Kataplana celeretrix is described as a new species of proseriate flatworm belonging to the Otoplanidae. This species was found in low-tide-level surface sediments at two high-energy beach sites in North Carolina and is unique among described Otoplanidae in possessing post-pharyngeal germaria. In addition, we consider the intermediate taxonomic position that this new species occupies between Parotoplaninae and Otoplaninae, and point to the utility of confocal microscopy in routine species descriptions.

Molecular Characters

Neacomys Thomas, 1900 is an oryzomyine genus comprising at least 17 lineages distributed from easternmost Panama to northern Bolivia. As is the case for other groups of the subfamily Sigmodontinae, Neacomys have experienced a substantial increase in the rate of species descriptions in the last two decades, prompted by the progressive generation of morphological, molecular and karyological data. Nevertheless, most of the studies related to the genus have focused on the assessment of Cis-Andean populations, so that the Trans-Andean ones have been relegated to the background. In more than a century, only two species have been described from that region, one of them present in Colombia (N. tenuipes Thomas, 1900). Here, a new species of Neacomys is named and described based on samples collected in montane ecosystems of the Serranía de los Yariguíes, an isolated massif in the Magdalena Valley (Trans-Andean Colombia). Its validity is supported by a unique combination of morphological and molecular characters: Neacomys sp. nov. can be distinguished from other congeners mainly by the presence of broad ochraceous-orange patches on the sides of the muzzle, a gray-based ochraceous buff ventral fur, a thick hamular process of the squamosal, an opened ectotympanic ring, and a narrow anterocone of M1. The species is recovered as a clearly divergent and well-supported monophyletic group in the phylogenies, which implies it is not closely related to any other species in the genus and probably represents an early radiation within it. The new species of Neacomys constitutes the only rodent described from Colombia in more than 50 years and brings the list of mammals of the country to 529 species. Its discovery evidences that Trans-Andean region could be an important source of hidden diversity for the genus, and in Colombia, for rodents in general. Thus, further inventories, especially into remote areas, are needed to unveil this diversity. The fact that the new species seems to be endemic to an isolated mountain range implies it merits attention in terms of conservation.
