The metathoracic wing venation in 41 species of 18 genera of Afrotropical Scutelleridae was studied and the results are presented and illustrated. Four main types of venational pattern can be recognized. The hindwing venation in Scutelleridae has also been compared with that of some other Pentatomoidea (Cydnidae, Dinidoridae, Pentatomidae and Tessaratomidae). Furthermore, the taxonomie value of metathoracic wing venation in the Afrotropical Scutelleridae has been discussed.
Forty nine species of jumping spiders from the Calabar area in southeastern Nigeria and two from Kaduna Junction in central northern Nigeria are listed in this paper. Among these, the following 8 species are described as new to science: Bacelarella gibbosa sp. nov. (♂ ♀ ), Brancus lacrimosus sp. nov. (♀), “Brancus” nigeriensis sp. nov. (♂), Mexcala smaragdina sp. nov. (♂), Phintella paludosa sp. nov. (♂), Thiratoscirtus atakpa sp. nov. (♀), Thiratoscirtus efik sp. nov. (♂) and Thiratoscirtus procerus sp. nov. (♀). Females of Baryphas jullieni Simon, 1902, Longarenus brachycephalus Simon, 1903 and Thiratoscirtus torquatus Simon, 1903 are described for the first time. Two species names are synonymized, Schenkelia gertschi Berland et Millot, 1941 with Schenkelia modesta Lessert, 1927 and Myrmarachne insulana Roewer, 1942 with Myrinarachne hesperia (Simon, 1887). Four new combinations are proposed, Viciria mondoni Berland et Millot 1941, Vidria niveimana Simon, 1902 and Viciria peckhamorum Lessert, 1927 are transferred to the genus Brancus, and Mithion grassei Berland et Millot, 1941 is transferred to the genus Pseudicius. Twenty eight salticid species are recorded for the first time in Nigeria.
Following eight species of dendryphantine jumping spiders are described as new to science: Deridryphantes elgonensis (♂), D. holmi (♂♀), D. luridus (♂♀), D. minutus (♂), D. serratus (♂), D. subtilis (♂), Rhene kenyaensis (♂) and R. mombasa (♀).D. hewitti is recorded in Kenya for the first time.
A new species of Phytodietus Gravenhorst, 1829, Ph. (Weisia) pearlus sp. nov. from the Republic of South Africa is described and compared with congeneric Afrotropical species.
Redescriptions of members of the African jumping spider genus Nigorelia are presented, key for males is provided and distribution map is given. One species from South Africa and Zimbabwe N. hirsuta sp. nov. is described. Phileus manicus and Pachypoessa albimana are removed from the synonyms of Euophrys plebeja. The name Euophrys plebeja is treated as nomen dubium.
Brachycyphon anthracinus Fairmaire, the type species of Brachycyphon Fairmaire is redescribed, its lectotype is designated. The genus Brachycyphon Fairmaire is compared with other Cyphon-like scirtid genera, a differential diagnosis and an identification key is provided. The following afrotropical taxa are transferred to Brachycyphon: Cyphon alberti Pic, Cyphon alexandri Pic, Cyphon atriceps Pic, Cyphon atricolor Pic, Cyphon atrofasciatus Pic, Cyphon atrovittatus Pic, Cyphon aymerichi Pic, Cyphon aymerichi tananarivanus Pic, Cyphon fairmairei Pic, Cyphon fasciatosinuatns Pic, Cyphon fuscopictus Fairmaire, Cyphon gerardi Pic, Cyphon gerardi basilewskyi Pic, Cyphon gerardi insuturalifer Pic, Cyphon grandenotatus Pic, Cyphon humerosus Fairmaire, Cyphon jeanneli Pic, Cyphon jeanneli innotaticollis Pic, Cyphon kijabensis Pic, Cyphon luteosignatus Pic, Cyphon oblongulus Fairmaire, Cyphon ovatulus Fairmaire, Cyphon plurisignatum Pic, Cyphon uviranus Pic, Cyphon villiersi Pic, Cyphon villiersi insignatus Pic, Elodes clemenceaui Pic, Elodes lloydi Pic, Elodes petaini Pic, Scirtes lippensi Pic, Scirtes seminiger Pic. Cyphon mimodiversicolor rutovuensis Pic and Cyphon mimodiversicolor semimarginatum Pic are elevated to species level and transferred to Brachycyphon. Brachycyphon afrosuturalis nom. nov. is proposed for Cyphon suturalis Pic, 1952 (nec Cyphon suturalis Tournier, 1868). Cyphon leoni Klausnitzer, 1974 is a new objective synonym of Cyphon fairmairei Pic, 1913. A catalogue of Brachycyphon is included.
