Within the framework of the preparation of the treatment of the family Dipterocarpaceae for the Flore d’Afrique Centrale, the revision of the genus Monotes in D.R. Congo is presented, including a discussion on its distinction from the closely related genus Marquesia. Monotes has suffered from taxonomic inflation. A much more synthetic treatment than earlier revisions is here proposed, with 15 new synonyms and seven species or subspecies downgraded to varietal rank. Twenty-seven taxa are accepted in D.R. Congo (13 species, 10 varieties and four forms), of which six are new to the flora of the country. One new species (Monotes duvigneaudii), one new subspecies (Monotes rubriglans subsp. upembensis) and three new varieties are described (Monotes dasyanthus var. heterotrichus, M. duvigneaudii var. concolor, M. rubriglans subsp. upembensis var. griseocoriaceus). Eleven new combinations are made. Monotes hypoleucus is extended, to include var. angolensis, var. caloneurus, var. discolor, var. hypoleucus, and var. loandensis. Lectotypes are designated for M. adenophyllus var. homblei, M. dasyanthus var. dasyanthus forma sericea, M. dasyanthus var. mutetetwa, M. dawei, M. glaber, M. hirtii, M. hypoleucus, M. hypoleucus var. angolensis, M. hypoleucus var. caloneurus, M. kapiriensis, M. katangensis, M. magnificus var. albidus, M. magnificus var. paucipilosus, and M. schmitzii. Four supposed Angolan endemics (M. carrissoanus, M. dawei, M. hutchinsonianus, M. noldeae) and one supposed Congolian endemic (M. schmitzii) are refuted as forms without taxonomic standing. Another three are no longer endemic to Angola because of material collected in D.R. Congo (M. hypoleucus var. loandensis, M. pearsonii, M. rubriglans). In the current state of knowledge, eight taxa are endemic to D.R. Congo (Monotes doryphorus, M. duvigneaudii var. duvigneaudii, M. duvigneaudii var. concolor, M. hirtii, M. hypoleucus var. angolensis f. oxyphyllinus, M. magnificus var. gigantophyllus, M. rubriglans subsp. upembensis var. upembensis and M. rubriglans subsp. upembensis var. griseocoriaceus). The Upper Katanga region appears to represent the most prominent centre of diversity for the genus. Additional field work and collecting is necessary to complete the description of several taxa.

The species of the Australian Hygrophoraceae are considered and three genera recognised: Hygrophorus Fr.; Hygrocybe (Fr.) Kummer; and Camarophyllopsis Herink. Fifty-seven taxa are described, of which 35 are new species, two are new varieties and six are new combinations; the position of Hygrocybe flammans (Berk.) A.M.Young remains uncertain. The taxa described are believed to represent less than 30% of the Australian family flora. Keys, descriptions and line drawings are provided to facilitate identification and a possible systematic structure is proposed. A brief review of Australian literature relevant to the family is provided.

Four additional species of quill mites of the family Syringophilidae Lavoipierre have now been recorded in England. This includes one new species, Bubophilus aluconis sp. nov., which parasitizes the tawny owl Strix aluco (Strigiformes: Strigidae). It differs from other species of this genus, B. ascalaphus Philips et Norton, 1978 and B. asiobius Skoracki et Bochkov, 2002 by the number of chambers in transverse branch of the peritremes (2-3), the length ratio of setae vi and ve (1:1.6-2), and the lengths of the stylophore and aggenital setae ag1 (180 and 135-145, respectively).

Sixty-two taxa are recognized in this study of the species of Puccinia completing their life cycle on Heliantheae. Six new species are described: Puccinia guatemalensis Parmelee on Zexmenia spp. and Wedelia spp., P. ghiesbreghtii Parmelee on Wedelia ghiesbreghtii, P. abramsii Parmelee on Geraea viscida (= Encelia viscida), P. chloracae Parmelee on Viguiera spp., P. calanticariae Parmelee on Viguiera spp., and P. praetermissa Parmelee on Lagascea spp. Six new varieties are recognized: Puccinia electrae var. robusta Parmelee and P. electrae var. depressiporosa Parmelee on Zexmenia brevifolia, P. caleae var. cuernavacae Parmelee on Calea spp., P. cognata var. echinulata Parmelee on Verbesina spp., P. cognata var. fraseri Parmelee on Viguiera fraseri, and P. affinis var. triporosa Parmelee on Viguiera spp. Three taxa have been restored from synonomy under P. abrupta, viz. P. subglobosa, P. ximenesiae, and P. affinis, the last two parasitic on Verbesina spp., the first on Rhysolepis (= Viguiera). P. tithoniae, P. nanomitra, and P. ordinata, are reduced to synonomy with P. enceliae var. enceliae, P. iostephanes, and P. melampodii respectively. New combinations include: P. enceliae var. aemulans (Syd.) Parmelee and P. abrupta var. partheniicola (Jacks.) Parmelee. A key based on uredinial and telial characters, others based initially on the hosts, and a host index are provided. Each taxon is illustrated by a photomicrograph from type material. Distribution and host extensions, supplementary to those given in Arthur's Manual of the Rusts, are indicated.

Approximately half of the species in speciose genus Raorchestes were described during the past 10 years, yet only 11 species are known from Southeast Asia and southern China (SEA-SC), adjacent Himalayas, and northeastern India. Field work in northwestern Yunnan province, China resulted in the discovery of one new species in the genus based on morphological and molecular analyses. The new species is diagnosed by small size with 15.0–19.0 mm SVL in adult males (n=3); tongue pyriform, notched posteriorly; rudimentary webbing between toes; fingers and toes with narrow lateral dermal fringes; tibiotarsal articulation reaching anterior of the eye when hindlimb is stretched along the side of the body; relative finger lengths: I < II < IV < III, relative toe lengths: I < II < V < III < IV; inner metatarsal tubercle oval, outer metatarsal tubercle absent; finger discs and toe discs greyish or orange; flank near the crotch with a distinct black region between two creamy white patches, and the thigh having a similar black patch near the groin, proximal to another creamy white patch; a distinct “) (”-shaped dark marking on the back; male with external single subgular vocal sac; nuptial pad absent. A phylogenetic tree was reconstructed based on the mitochondrial genes for 16S rRNA and ND1. The results indicated that these individuals form a monophyletic group, and show high genetic divergence to their closest relatives within the genus (uncorrected p-distances > 3.2%) by distance of 16S comparable to the divergence between recognized Raorchestes species. This study further enriches the diversity of rhacophorids, especially in northwestern Yunnan.
