A new genus and six new species of the family Gomphodesmidae from the Udzungwa Mts are described, including Pogoro alopias Rosenmejer & Enghoff sp. nov., Pogoro siren Rosenmejer & Enghoff sp. nov., Pogoropsis prolixopes Rosenmejer & Enghoff gen. et sp. nov., Emphysemastix frampt Olsen & Enghoff sp. nov., Agrophogonus hamulus Olsen & Enghoff sp. nov., and Agrophogonus pusillokiellandi Olsen & Enghoff sp. nov. Emphysemastix dracarys Olsen & Enghoff sp. nov. from Iringa city is described. Descriptive notes are given for Pogoro scharffi Hoffman, 2005, and Agrophogonus mwanihana Hoffmann, 2005. General gomphodesmid gonopod morphology is described and illustrated. A key to Udzungwa gomphodesmids is presented, as well as revised keys to all species of Emphysemastix and Agrophogonus. All gomphodesmid species from the Udzungwa Mts are mapped.
A large, newly collected material of the genus Aquattuor from the Udzungwa Mts, Tanzania, has been studied. Two new species are described, viz., A. mollilobus sp. nov. from the Udzungwa Mts and A. nguruensis sp. nov. from the Nguru Mts, Tanzania. Aquattuor claudiahempae Enghoff & Frederiksen, 2015, is recorded as new for the Udzungwa fauna. Characters from the first pair of male legs are illustrated for all Aquattuor species and are shown to be useful for species discrimination. A new gonopodal difference between A. submajor Enghoff, 2015 and A. udzungwensis Enghoff, 2015 is described and illustrated. Intrageneric relationships and distribution patterns are discussed. A distribution map and a key to all Aquattuor species are presented.
A new giant species of the subfamily Rhynchoproctinae with strikingly bi-coloured, red-yellow legs contrasting with a black body is described: Alienostreptus bicoloripes sp. nov. from Vietnam. The new species is assigned to the genus Alienostreptus Pimvichai, Enghoff & Panha, 2010 hitherto comprising one species, A. alienus (Attems, 1936), and differing from other rhynchoproctine genera by having the femoral spine duplicated. Species of this genus share three synapomorphic characters of the subfamily, viz (1) anterior coxal fold forms deep concavity in posterior view, (2) posterior coxal fold very low, and (3) posterior coxal fold with mesal flap. A superficially very similar colourful species from Borneo, also with bi-coloured legs but clearly not belonging to Alienostreptus due to the position of ventral soft pads on male legs, is documented based on photographs.
This is the second part of a study of a large collection of Siphonophoridae Cook, 1895 from Brazil. Here, those without an abrupt division between the head and rostrum are considered. Two species have been distinguished and are described as Siphonophora setaepromissa sp. nov. and S. tuberculata sp. nov. Siphonophora hebetunguis (Attems, 1951) from the same region has many similarities with the two new species and is redescribed from type material. Comparisons have also been made with S. fuhrmanni Carl, 1914, and comments are made on the genera Cordillerium Verhoeff, 1941, Pterozonium Attems, 1951, Rhinosiphora Verhoeff, 1924, and Siphonophora Brandt, 1837. Finally, some suggestions for characters to look at in future collections of siphonophorids are made based on experience of this collection.
We revise the genus Attemsostreptus Verhoeff, 1941 based on type material of the type species, A. costatus Verhoeff, 1941, synonymise A. orobius (Kraus 1958) with A. costatus and describe a second species of the genus, A. reflexus sp. nov., collected from Kimboza Forest Reserve in Tanzania, and discuss the dubious tribe Trachystreptini.
Jeekelosoma Mauriès, 1985, is upgraded from subgenus status under Eviulisoma Silvestri, 1910 to full genus status. The type species, Jeekelosoma abadi (Mauriès, 1985) is redescribed based on topotypical material from a cave in Morocco. Jeekelosoma heptarachne sp. nov. and J. viginti sp. nov. are described from two further Moroccan caves.
Damacornu gen. nov. (type species: D. transversum gen. et sp. nov.), Geotypodon papei sp. nov. and Spinotarsus fortehamatus sp. nov. are described, and Helicochetus dimidiatus (Peters, 1855), H. mutaba Kraus, 1960 and Hoffmanides dissutus (Hoffman, 1963) are recorded from the Udzungwa Mts, Tanzania. A complete overview of the 39 odontopygid species now known from the Udzungwa Mts is given, including notes on endemism, biogeographical relationships and altitudinal distribution patterns.
We describe five new species of fungi of the order Laboulbeniales Lindau growing on millipedes and belonging to the genera Diplopodomyces W.Rossi & Balazuc and Troglomyces S.Colla. Three new species of Diplopodomyces, viz. Diplopodomyces coronatus Santam., Enghoff & Reboleira sp. nov. living on Serboiulus spelaeophilus Gulicka, 1967 from Bulgarian caves, Diplopodomyces liguliphorus Santam., Enghoff & Reboleira sp. nov. on an unidentified species of Spirobolida from Sri Lanka, and Diplopodomyces ramosus Santam., Enghoff & Reboleira sp. nov. on Pachyiulus spp. from Turkey, Macedonia and Serbia; and two new species of Troglomyces, viz. Troglomyces dioicus Santam., Enghoff & Reboleira sp. nov. on Nepalmatoiulus sp. from Myanmar, and Troglomyces tetralabiatus Santam., Enghoff & Reboleira sp. nov. on Caucaseuma Strasser, 1970 and Heterocaucaseuma Antić & Makarov, 2016 from caves in Western Caucasus. Troglomyces dioicus sp. nov. is the first dioecious species described in the genus Troglomyces. Keys for all hitherto known species of Diplopodomyces and Troglomyces are presented, as is a discussion of the status of both genera. Additional records for Diplopodomyces lusitanipodos Santam., Enghoff & Reboleira and Troglomyces manfrediae S.Colla are also included.
The ‘gigas’ group of dragon millipedes, formerly placed in the genus Desmoxytes Chamberlin, 1923, is revised and assigned to the new genus Gigaxytes gen. nov. Desmoxytes gigas Golovatch & Enghoff, 1994 is the type species of the new genus and is redescribed as G. gigas (Golovatch & Enghoff, 1994) gen. et comb nov. Three new species are described: G. fusca gen et sp. nov. from Thailand and Myanmar; G. parvoterga gen et sp. nov. and G. suratensis gen et sp. nov. from Thailand. All Gigaxytes species are endemic to small distribution areas in limestone habitats in South Thailand and South Myanmar. Illustrations of external morphological characters and an identification key to all known species are provided as well as a distribution map.
