The genus Dendrobia n. gen. is erected to include D. amaniensis n. sp. from the East Usambara Mountains as type species. A second species in this genus, D. octopuncata n. sp., is described from the Udzungwa Mountains of Tanzania. Dendrobia n. gen. is a canopy dweller found only high up on trees in closed submontane and montane forest. The peak frequency of its song is lower than in all other known African Agraeciini, correlating with the large resonant areas in the tegmina. Two new Afroanthracites species, A. ngologolo n. sp. and A. nguru n. sp. are described from the Eastern Arc Mountains in Tanzania. These species are dwellers of understory vegetation in closed forest in the Udzungwa and Nguru Mountains respectively.

Twenty-two new species of the genus Eviulisoma Silvestri, 1910, from the Eastern Arc Mountains, Tanzania, are described: E. acaciae sp. nov., E. aequilobatum sp. nov., E. akkariae sp. nov., E. angulatum sp. nov., E. articulatum sp. nov., E. biquintum sp. nov., E. breviscutum sp. nov., E. cetafi sp. nov., E. chitense sp. nov., E. commelina sp. nov., E. coxale sp. nov., E. ejti sp. nov., E. grumslingslak sp. nov., E. kalimbasiense sp. nov., E. navuncus sp. nov., E. nessiteras sp. nov., E. ottokrausi sp. nov., E. paradisiacum sp. nov., E. sternale sp. nov. and E. zebra sp. nov. from the Udzungwa Mts, E. culter sp. nov. from the Rubeho Mts and E. kangense sp. nov. from the Kanga Mts. Eviulisoma kwabuniense Kraus, 1958, and E. dabagaense Kraus, 1958, both from the Udzungwa Mts, are redesribed based on new material. Notes are provided on E. iuloideum (Verhoeff, 1941) based on type material. Eoseviulisoma Brolemann, 1920, is synonymized under Eviulisoma, based on newly collected material of E. julinum (Attems, 1909), type species of Eoseviulisoma. New material of Suohelisoma ulugurense Hoffman, 1964, type species of Suohelisoma Hoffman, 1964, has revealed that the gonopod structure is more similar to that of Eviulisoma than originally thought, but Suohelisoma is retained as a valid genus. Four species groups are recognized among Eviulisoma species from the Udzungwa Mts, but the need for a revision of the entire genus is emphasized. Two types of epizootic fungi are recorded from Eviulisoma spp., and an enigmatic amorphous mass, which may be a kind of plugging substance, is recorded from the gonopod tips and excavated sixth sternum of several species.

This paper reports discovery of a new genus <em>Lupangus</em> gen. n. with three new flightless weevils endemic to the forests of the Eastern Arc Mountains in Tanzania: <em>L. asterius</em> sp. n. (East Usambara; the type species), <em>L. jason</em> sp. n. (Uluguru) and<em> L. orpheus</em> sp. n. (Udzungwa). Maximum Likelihood phylogenetic analyses using parts of mitochondrial (COI), nuclear ribosomal (28S) genes, as well as the nuclear spacer region (ITS2) from 46 terminals grouped together the reciprocally monophyletic <em>Lupangus</em> (3 terminals) and <em>Typoderus</em> (3 terminals), with all three clades strongly supported. Phylogenetic analysis of 32 COI-5’ sequences recovered <em>Lupangus</em> species as reciprocally monophyletic, with <em>L</em>. <em>orpheus</em> being the sister to the rest. Internal phylogeny within both <em>L. jason</em> and <em>L.</em> <em>orpheus</em> are geographically structured, while that of <em>L. asterius</em> is not. Temporal analysis of <em>Lupangus</em> evolution using COI-5’ data assessed under slow and fast substitution rate schemes estimated separation of mitochondrial lineages leading to three <em>Lupangus</em> species at about 7–8 Ma and about 1.9–2.1 Ma, respectively. Temporal analyses consistently failed to suggest correlation between the timing of <em>Lupangus</em> evolution and the late Pleistocene climatic fluctuations, thus rejecting the hypothesis of faunal interchanges during the wettest periods of the last million years. Applicability of flightless weevils for dispersal-vicariance analysis is reviewed, and their mostly undocumented and taxonomically entangled diversity in the Tanzanian Eastern Arc Mountains is briefly highlighted.

The nine genera of the Afrotropical Ommatiinae are briefly reviewed and include a revised key to genera. A new genus and a species group are diagnosed and described. New genus: Longibeccus (type species, O. fuscovittatus Ricardo, 1900). New combinations: Transferred to Longibeccus from Ommatius, 1821: O. fuscovittatus Ricardo, 1900, and O. imperator Oldroyd, 1939. New status: subgenus Metommatius Hull, 1962, is elevated to generic level. New species group: neotenellus includes Ommatius coperitus n. sp., O. latus n. sp., O. neotenellus Bromley, O. polixus n. sp., and O. ultimus n. sp. from east Africa. The male of O. neotenellus is described for the first time. Only one species of Michotamia (M. coarctata Macquart, 1855), is confirmed from Madagascar. New synonymies: Afroestricus minutus (Bromley 1936)=Ommatius flavipes Loew, 1860; Michotamia cothurnata (Bigot, 1875)=Cophinopoda pulchripes (Bigot,1859). Illustrations of heads, antennae, wings, and terminalia of selected species and keys to the species of Longibeccus and the neotenellus group are provided. Distributions of the Afrotropical genera are briefly discussed.

AbstractThe rhytirrhinine genus Andesianellus gen. n. (type species A. microphthalmicus sp. n.), and nine new species, are described from the highlands of Colombia (1), Ecuador (5), and Peru (3). Andesianellus species are characterized by the following combination of character states: very small body size (< 3.5 mm), eyes reduced to 8 or fewer facets, rostrum distinctly tricarinate dorsally, and basal elytral margin raised and subcarinate. Most specimens were collected in berlese funnel samples of various kinds of montane forest leaf litter. The closest relatives are hypothesized to be the Andean genera Adioristidius Voss and Macrostyphlus Kirsch.

The new zoropsid spider genus Chinja Polotow & Griswold is diagnosed and described and the following two new species are described: C. chinja sp. nov. and C. scharffi sp. nov. The species were collected in the Eastern Arc Mountains of Tanzania and appear to be endemic to this region. The genus belongs to the oval-calamistrum clade (OC Clade), which also includes Dionycha and Lycosoidea. Based on the synapomorphies and diagnostic characters of members of the OC Clade, Chinja is considered a member of Zoropsidae, although without a clear subfamily placement due to insufficient data. Males of Chinja can be distinguished from other Zoropsidae by a straight PER, by lacking a tibial crack, by having a male palpal cymbium with a retrobasal process and the male palpal tibia with an RTA and a retromedian cluster of stout setae. Females have a divided cribellum with cribellar spigots evenly arranged, and the epigynum with the median plate broad and laterally procurved into hooks, and the lateral lobes each with a wide tooth. The following set of characters can be also helpful to identify the genus: presence of a third tarsal claw, absence of claw tufts and presence of a cribellum and calamistrum.

Three New Species

The Andean cloud forests of western Colombia and Ecuador are home to several endemic mammals; members of the Oryzomyini, the largest Sigmodontinae tribe, are extensively represented in the region. However, our knowledge about this diversity is still incomplete, as evidenced by several new taxa that have been described in recent years. Extensive field work in two protected areas enclosing remnants of Chocó montane forest recovered a high diversity of small mammals. Among them, a medium-sized oryzomyine is here described as a new genus having at least three new species, two of them are named and diagnosed. Although externally similar to members of the genera Nephelomys and Tanyuromys, the new genus has a unique molar pattern within the tribe, being characterized by a noticeable degree of hypsodonty, simplification, lamination, and third molar compression. A phylogeny based on a combination of molecular markers, including nuclear and mitochondrial genes, and morphological data recovered the new genus as sister to Mindomys, and sequentially to Nephelomys. The new genus seems to be another example of a sigmodontine rodent unique to the Chocó biogeographic region. Its type species inhabits cloud forest between 1,600 and 2,300 m in northernmost Ecuador (Carchi Province); a second species is restricted to lower montane forest, 1,200 m, in northern Ecuador (Imbabura Province); a third putative species, here highlighted exclusively by molecular evidence from one immature specimen, is recorded in the montane forest of Reserva Otonga, northern Ecuador (Cotopaxi Province). Finally, the new genus is also recorded in southernmost Colombia (Nariño Department), probably represented there also by a new species. These species are spatially separated by deep river canyons through Andean forests, resulting in marked environmental discontinuities. Unfortunately, Colombian and Ecuadorian Pacific cloud forests are under rapid anthropic transformation. Although the populations of the type species are moderately abundant and occur in protected areas, the other two persist in threatened forest fragments.
