AbstractThe genus Cricotopus of the arctic zone of the Nearctic region, represented by 14 species in seven species groups, is reviewed. Descriptive notes on 11 species supplement those given by Hirvenoja (1973), with addition of descriptions of immature stages of C. lestralis (Edwards) and larva of C. tristis Hirvenoja. Two new species names, C. beringensis and C. trilobus, are proposed. New species names synonymies are Chironomus basalis Staeger and Chironomus holmgreni Kieffer with Chironomus tibialis (Meigen) (= C. tibialis). Several undetermined individuals are assigned to the fuscus group. Eleven species are Holarctic in distribution, of which C. bicinctus (Meigen) and C. sylvestris (Fabricius) are circumboreal. Seven species are restricted to the arctic zone, two are wide-ranging in both arctic and temperate zones, and four temperate species barely extend into the arctic zone. Keys to all known life-history stages and some ecological data, primarily of larvae, are given.

AbstractThere are 16 species of Trichoclinocera Collin recognized from the Nearctic region, including eight new species. Four of six species-groups of Trichoclinocera are recognized in the Nearctic region, with the following included species: (1) T. comata group — T. cascadensis sp.nov. (type-locality Starvation Creek, Oregon, U.S.A.), T. comata (Melander) comb.nov., and T. rupestris sp.nov. (type-locality Newton Creek, Wyoming, U.S.A.); (2) T. dolicheretma group — T. dolicheretma (Melander); (3) T. lapponica group — T. lapponica (Ringdahl) comb.nov.; (4) T. longipes group — T. agilis sp.nov. (type-locality Fall Creek Falls, Tennessee, U.S.A.), T. ctenistes (Melander), T. dasycoxa sp.nov. (type-locality Ottawa, Ontario, Canada), T. falcata sp.nov. (type-locality Gatineau Park, Quebec, Canada), T. fumosa (Vaillant) comb.nov., T. hamifera (Melander), T. longipes (Walker). T. minor (Melander), T. ozarkensis sp.nov. (type-locality Haw Creek Falls, Arkansas, U.S.A.), and T. pectinifemur sp.nov. (type-locality Phoenixville, Pennsylvania, U.S.A.). The following new synonyms are proposed: T. brunnipennis (Melander) = T. dolicheretma; and Seguyella saltans (Vaillant) = T. hamifera. Lectotypes are designated for T. comata, T. ctenistes, T. dolicheretma, T. brunnipennis, T. hamifera, T. lapponica, and T. stackelbergi Collin. Seguyella Vaillant and Acanthoclinocera Saigusa are newly synonymized with Trichoclinocera and all species formerly placed in these genera are transferred to Trichoclinocera, except Acanthoclinocera glaucescens (Brunetti) which is transferred as Wiedemannia glaucescens (Brunetti) comb.nov.This revision includes a key to Nearctic species, a description of each species, and maps of species distributions. Homologies of male terminalia of Clinocerinae are summarized and the first descriptions of the immature stages of species of Trichoclinocera also are provided. A world list of described species of Trichoclinocera is provided and all species are assigned to one of six species-groups, except T. cummingi sp.nov. (type-locality Robber’s Cave, Oklahoma. U.S.A.), T. fluviatilis (Brunetti) comb.nov., T. fuscipennis Saigusa, and T. maewa Smith, which remain unplaced. The monophyly of Trichoclinocera is justified and phylogenetic relationships to the remaining Clinocerinae and among species-groups are discussed.

An integrative taxonomy approach was implemented based on analysis of genetic, phylogenetic, morphological and ecological data to identify the cryptic diversity within the Phyllodactylus lanei complex. At least six species can be identified, of which four are currently considered subspecies: Phyllodactylus lanei, Phyllodactylus rupinus, Phyllodactylus isabelae, Phyllodactylus lupitae and two corresponding to undescribed taxa, which are identified and described in this contribution. These differ from other Mexican geckos in several characters: genetic distance (DNAmt), position in molecular phylogeny (concatened data DNAmt+DNAnu), species tree, morphological characters such as snout-vent length, longitudinal scales, tubercles from head to tail, interorbital scales, scales across venter, third labial–snout scales and rows of tubercles across dorsum; there are also differences in their bioclimatic profiles (temperature and precipitation) and geographical distribution. The most recent studies on taxonomy and evolution of Mexican geckos (Phyllodactylus) show that the diversity of this group of reptiles is currently underestimated, suggesting that more research and conservation efforts are should be addressed at these lizards.

Two new species of Leptomorphus Curtis, L. guatemalensis sp. n. and L. juxtafurcatus sp. n., are described from Guatemala, figured, and compared with congeners. The new species belong to the clade including the “furcatus” and “walkeri” species-groups as defined by Borkent & Wheeler (2012). L. guatemalensis sp. n. can be recognized by the gonocoxite bulbous and crescent-shaped with the apex asetose and spatula-like, but remains without a clear sister-species. Based on the structure of the male terminalia, particularly the presence of submedian, pointed lobes on sternite nine, L. juxtafurcatus sp. n. is suggested to be the sister-species to L. furcatus Borkent from the southwestern USA and northern Mexico; these species can be distinguished by the form of the gonocoxites.

This is the first record of the genus Ljania Thor, 1898 (Axonopsinae, Aturidae, Hydrachnidiae, Acari) from China. Two new species, Ljania jini sp. nov. and Ljania guangxiensis sp. nov., are described from Guangxi Province, P. R. China. The new detections bring the total number of Chinese aturid mites to eleven species, representing seven genera.

Eutarsopolipus burwelli sp. nov. and E. echinatus sp. nov. (Acari: Podapolipidae) are described from Nurus medius Darlington, 1961 (Coleoptera: Carabidae), a large burrowing carabid beetle found in the rainforests of coastal central Queensland, Australia. Eutarsopolipus burwelli belongs to the ochoai species group, which is herein refined, and E. echinatus is placed tentatively in the pterostichi species group. A revised key to the species groups of Eutarsopolipus is provided. The synhospitalic species of Eutarsopolipus are reviewed and synhospitality within the genus is discussed.

The genus Nebrioporus Régimbart, 1906 is reviewed and partially revised. The historical subgeneric divisions have not been subscribed to here because they fail to reflect the natural grouping within the genus. Instead, Nebrioporus has been divided into eight species-groups recognised and described with character analysis and keys for their identification. The N. laeviventris-group, comprising 4 subgroups and 13 species, has been revised. The N. depressus-group, the most speciose within the genus, is redefined and dealt with in detail with keys for the identification of the species and morphological illustrations accompanying the taxonomic discussion for selected species. The N. sansii-group, as here defined, is also keyed and illustrated and the species N. lynesi (J. Balfour-Browne, 1947) is revised and inserted into this group. Revisional notes are provided also for the following species: Nebrioporus canariensis (Bedel, 1881), N. capensis (Omer-Cooper, 1953), N. dubius (Aubé, 1838b), N. kiliani (Peyerimhoff, 1929), N. kilimandjarensis (Régimbart, 1906), N. seriatus (Sharp, 1882), N. simplicipes (Sharp, 1884), N. solivagus (Omer-Cooper, 1965), N. vagrans (Omer-Cooper, 1953). All revised species are provided with a short redescription, illustration of diagnostic characters and distributional analysis. For several species new distributional records are given. Illustrations of habitus and male characters are provided also for species not discussed in the text. A comprehensive checklist of the genus Nebrioporus is given, with synonyms. Two new species are described: N. amicorum sp.n. from Crete and N. sagartus sp.n. from Iran, both belonging to the N. laeviventris-group, the former described from material previously determined as Nebrioporus stearinus (Kolenati, 1854). Nebrioporus seriatus (Sharp, 1882) is found to be a member of the abyssinicus-group and inserted into previous identification keys. Nebrioporus suavis (Sharp, 1882) is here considered as a western subspecies of N. stearinus (new status as Nebrioporus stearinus suavis (Sharp)). New synonyms: Zimmermannius Guignot, 1941 = Nebrioporus Régimbart, 1906; Hydroporus walkeri Branden, 1885 = Hydroporus crotchi Preudhomme de Borre, 1871; Hydroporus variegatus Aubé, 1838a = Hydroporus stearinus Kolenati, 1845; Deronectes turca Seidlitz, 1887 = Hydroporus stearinus Kolenati, 1845; Potamonectes sulphuricola Zaitzev, 1951 = Hydroporus airumlus Kolenati, 1845. Lectotypes are designated for: Hydroporus clarkii Wollaston, 1862; Deronectes simplicipes Sharp, 1884; Deronectes anchoralis Sharp, 1884; Hydroporus kiliani Peyerimhoff, 1929; Deronectes seriatus Sharp, 1882; Deronectes arabicus Sharp, 1882; Deronectes islamiticus Sharp, 1882; Deronectes princeps Sharp, 1882; Hydroporus stearinus Kolenati, 1845; Deronectes suavis Sharp, 1882; Hydroporus crotchi Preudhomme de Borre, 1871; Hydroporus insignis Klug, 1833; Hydroporus semiclusus Walker, 1871; Deronectes hostilis Sharp, 1884; and Hydroporus melanogrammus Régimbart, 1899.
