Eight species of Diplopeltoides are described from the Swedish west coast. Diplopeltoides suecicus sp. nov. has the cuticle with longitudinal striation visible only under SEM; cuticular plate underlying the cephalic cuticle around the amphid present; cephalic sensilla 4–6 μm long; amphid an inverted U-shape; wide space between amphidial branches areolated; spicules 27–31 μm long; gubernaculum with caudal apophysis. Diplopeltoides longicaudatus sp. nov. is characterized by a cuticle without longitudinal striation; cuticular plate underlying cephalic cuticle around amphid present; cephalic sensilla 13 μm long; amphid an inverted U-shape; narrow space between amphidial branches not ornamented; spicules unequal in size, 27–31 μm long; gubernaculum absent; midventral precloacal cuticular ridge present. D. grandis sp. nov. is characterized by a cuticle with longitudinal striation; cuticular plate underlying cephalic cuticle around amphid present; cephalic sensilla 18.5 μm long; amphid an inverted U-shape; wide space between amphidial branches punctate. The following taxonomic changes are proposed: Diplopeltoides asetosus (Juario, 1974) comb. nov., Diplopeltoides botulus (Wieser, 1959) comb. nov., Diplopeltoides bulbosus (Vitiello, 1972) comb. nov., Diplopeltoides lucanicus (Boucher & Helléouët, 1977) comb. nov., Diplopeltoides pumilus (Vincx & Gourbault, 1992) comb. nov. and Diplopeltoides striatus (Gerlach, 1956) comb. nov. Diplopeltoides holovachovi Fadeeva & Mordukhovich, 2013 is synonymised with Diplopeltoides pumilus comb. nov. An updated key to the species of Diplopeltoides is provided.
The genus Dasydorylas Skevington, 2001 is recorded from two provinces in Iran (Sistan-o Baluchestan and Kermanshah Provinces). Dasydorylas derafshani sp. nov. and D. zardouei sp. nov. are characterized morphologically by DNA barcoding of the mitochondrial COI gene. Eudorylas antennalis Kapoor, Grewal & Sharma, 1987 is transferred to Dasydorlyas (comb. nov.). An existing identification key to the males of the western Palaearctic species of Dasydorylas is complemented to include the newly described species.
This study reviews the taxonomy of the ant genus Nesomyrmex Wheeler, 1910 in the Afrotropical region. Previous revisionary studies are discussed and four species groups are proposed on the basis of external morphology. The N. angulatus group contains seven species that are widely distributed throughout the whole Afrotropical region, with one species also occurring in the Palaearctic and Malagasy regions. The N. cataulacoides group is monotypic, with one morphologically bizarre species found in Equatorial rain forests. The N. humerosus group is also monotypic and occurs in East Africa. The last and by far most species-rich group is the N. simoni group that contains 17 species, all of which are endemic to South Africa. The four groups are defined for the first time for the region, and an illustrated identification key is provided. Furthermore, the N. angulatus group is more thoroughly reviewed. One new species from Mozambique is described, N. inhaca sp. nov., and species accounts for the other six are provided. Also, an illustrated identification key to the species of the N. angulatus group is presented.
This paper deals with the taxonomy and faunistics of the genus Diplommatina in Nepal. Altogether 16 species are reported, seven of which are new to science viz. D. abiesiana sp. nov., D. fistulata sp. nov., D. godawariensis sp. nov., D. maipokhariensis sp. nov., D. salgharica sp. nov., D. shivapuriensis sp. nov. and D. syabrubesiensis sp. nov. Information on nine previously reported species is provided: D. exserta Godwin-Austen, 1886, D. folliculus (L. Pfeiffer, 1846), D. miriensis Godwin-Austen, 1917, D. munipurensis Godwin-Austen, 1892, D. oviformis Fulton, 1901, D. pachycheilus Benson, 1857, D. regularis Fulton, 1901, D. silvicola Godwin-Austen, 1886 and D. sperata W.T. Blanford, 1862. Although D. canarica was once reported from Nepal, it is not treated here as it is an endemic of the Western Ghats. A dichotomous identification key for all Nepalese species is presented.
In this work we present a revision of the genus Ommatoiulus Latzel, 1884 in Portugal. Based on recently collected material and older museum samples, including type specimens, we describe six new species to science, viz. Ommatoiulus alacygni sp. nov., O. camurus sp. nov., O. denticulatus sp. nov., O. litoralis sp. nov., O. staglae sp. nov. and O. stellaris sp. nov. The species O. alacygni sp. nov., O. denticulatus sp. nov. and O. staglae sp. nov. described from the Algarve are outstanding by their extremely reduced mesomerital process. The species O. porathi (Verhoeff, 1893) and O. andalusius (Attems, 1927) are recorded and redescribed for the first time after their original description. The finding of O. andalusius – originally described from Andalusia in Spain – constitutes a new record for Portugal together with two species, viz. O. fuentei (Brolemann, 1920) and O. martensi Mauriès, 1969. The taxonomic status of several species is revised. Thus Archiulus (Schistocoxitus) cingulatus Attems, 1927 is here considered as a junior synonym of Ommatoiulus lusitanus (Verhoeff, 1895) while Schizophyllum cervinum Verhoeff, 1910 is synonymized with Ommatoiulus moreleti (Lucas, 1860). An identification key to all hitherto known Portuguese species of Ommatoiulus is presented as well as a distribution map illustrating the various species occurrences in the country.
