Description of a new species of <Emphasis Type="Italic">Amblyomma</Emphasis> Koch, 1844 (Acari: Ixodidae), parasite of deer (Artiodactyla: Cervidae) and wild pigs (Artiodactyla: Suidae) in the Philippines

Amblyomma anicornuta n. sp. (Acari: Ixodidae) is described based on adults and nymphs ex deer (Artiodactyla: Cervidae) and wild pigs (Artiodactyla: Suidae) from Luzon, Philippines. Adults of A. anicornuta n. sp. are similar to those of several Asian and Australasian species of Amblyomma Koch, 1844 with a 4/4 dental formula on the hypostome but can be distinguished by the colouration and pattern of punctations on the conscutum in the male and scutum in the female, the absence of a marginal groove on the conscutum in the male, the possession of long, thick, prominent setae on the alloscutum in the female, projections on anal valves and sclerotised ring around them in the male, a large median sclerite ventrally in the male, as well by the shape of the genital aperture in the female and the size and shape of spurs on coxae I–IV in both sexes. The nymph of A. anicornuta n. sp. is somewhat similar to that of A. babirussae Schulze, 1933 and A. geoemydae (Cantor, 1847) but can be distinguished by the colouration pattern on the scutum, the presence of dorsal cornua and the size of the spurs on coxae I–IV.     

Two new species of Haemaphysalis Koch, 1844 (Acari: Ixodidae) in the H. (Rhipistoma) spinulosa subgroup,parasites of carnivores and hedgehogs in Africa

Haemaphysalis (Rhipistoma) princeps n. sp. (Acari: Ixodidae) and H. (R.) camicasi n. sp. are described based on adults. Adults of H. princeps n. sp. were mostly collected from various carnivores (Carnivora: Canidae, Felidae, Herpestidae, Mustelidae, Viverridae) and hedgehogs (Erinaceomorpha: Erinaceidae); few specimens were found on hare (Lagomorpha: Leporidae), various rodents (Rodentia: Muridae) and an antelope (Artiodactyla: Bovidae) in Benin, Burkina Faso, Cameroon, Chad, Côte d’Ivoire, Ghana, Mali, Nigeria, Senegal, South Sudan and Sudan. Few adults of H. princeps n. sp. were reared from nymphs collected on rodents (Rodentia: Muridae) and shrew (Soricomorpha: Soricidae). Adults of H. camicasi n. sp. were also mostly collected from various carnivores (Carnivora: Canidae, Felidae, Herpestidae, Mustelidae, Viverridae) and hedgehogs (Erinaceomorpha: Erinaceidae); few specimens were found on different rodents (Rodentia: Muridae, Nesomyidae, Sciuridae), hare (Lagomorpha: Leporidae) and bushbaby (Primates: Galagidae) in Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Côte d’Ivoire, Nigeria, Senegal, South Sudan and Togo. Males and females of both species can be differentiated from each other and other H. spinulosa-like ticks by their size, pattern of punctations on conscutum/scutum, size of setae, shape of genital structures, size and shape of spiracular plates, dorsal cornua, posterodorsal and posteroventral spurs on palpal segments II and spur on coxae.

Amblyomma boeroi n. sp. (Acari: Ixodidae), a parasite of the Chacoan peccary Catagonus wagneri (Rusconi) (Artiodactyla: Tayassuidae) in Argentina

All parasitic stages of Amblyomma boeroi n. sp. (Acari: Ixodidae) are described here from Catagonus wagneri (Rusconi) in Argentina. The diagnostic characters for the male are a combination of orbited eyes, a 2/2 dental formula, coxa IV considerably larger than coxae I–III and with a long, sickle-shaped, medially directed spur arising from its internal margin, a scutum which is light grey to very pale ivory in colour, and the absence of a postanal groove. The diagnostic characters for the females are a combination of orbited eyes, a central pair and two marginal pairs of short, coarse notal setae, a 2/2 dental formula, and the absence of a postanal groove. The nymph has short palpi and a 2/2 dental formula arranged in 6 rows, its eyes are convex and orbited, and it has no postanal groove. The dorsally rectangular basis capituli of the larva, its bulging eyes and slightly sinuous posterior scutal margin all serve to distinguish it from the larva of other species of the genus. The principal host for all parasitic stages is C. wagneri (Artiodactyla: Tayassuidae). Phylogenetically A. boeroi appears to represent an independent lineage within Amblyomma Koch, 1844.     

Description of three new species of Ixodes Latreille, 1795 (Acari: Ixodidae), parasites of tenrecs (Afrotheria: Tenrecidae) on Madagascar

Ixodes soarimalalae n. sp., Ixodes uilenbergi n. sp. and Ixodes uncus n. sp. (Acari: Ixodidae), are described based on females ex various species of tenrecs (Afrosoricida: Tenrecidae) from Madagascar. Females of all of these new species are similar to those of other species of the subgenus Afrixodes Morel, 1966 known from Madagascar, from which they can be distinguished and from one other by the size of scutum, size of scutal setae, shape of alloscutal setae, shape of genital aperture, development of genital apron, size of auriculae, size of anterior angle of basis capituli, size of palpi, dental formula on hypostome and size and development of spurs on coxa I.

     

Rethinking the evolution of extant sub‐Saharan African suids (Suidae,Artiodactyla)

Gongora, J., Cuddahee, R. E., do Nascimento, F. F., Palgrave, C. J., Lowden, S., Ho, S. Y. W., Simond, D., Damayanti, C. S., White, D. J., Tay, W. T., Randi, E., Klingel, H., Rodrigues‐Zarate, C. J., Allen, K., Moran, C. & Larson, G. (2011). Rethinking the evolution of extant sub‐Saharan African suids (Suidae, Artiodactyla). —Zoologica Scripta, 40, 327–335. Although African suids have been of scientific interest for over two centuries, their origin, evolution, phylogeography and phylogenetic relationships remain contentious. There has been a long‐running debate concerning the evolution of pigs and hogs (Suidae), particularly regarding the phylogenetic relationships among extant Eurasian and African species of the subfamily Suinae. To investigate these issues, we analysed the mitochondrial and nuclear DNA sequences of extant genera of Suidae from Eurasia and Africa. Molecular phylogenetic analyses revealed that all extant sub‐Saharan African genera form a monophyletic clade separate from Eurasian suid genera, contradicting previous attempts to resolve the Suidae phylogeny. Two major sub‐Saharan African clades were identified, with Hylochoerus and Phacochoerus grouping together as a sister clade to Potamochoerus. In addition, we find that the ancestors of extant African suids may have evolved separately from the ancestors of modern day Sus and Porcula in Eurasia before they colonised Africa. Our results provide a revision of the intergeneric relationships within the family Suidae.

Revision of the Cales noacki species complex (Hymenoptera,Chalcidoidea, Aphelinidae)

The genus Cales (Hymenoptera: Aphelinidae) includes 13 species worldwide, of which 10 form a highly morphologically uniform species complex with a native range in the Neotropical region. We recognize ten species previously attributed to a single Neotropical species, Cales noacki Howard, which in the strict sense is a species broadly disseminated to control woolly whitefly. A neotype is designated for C. noacki, and it is redescribed based on specimens molecularly determined to be conspecific with the neotype. Newly described species include: C. bicolor Mottern, n.sp ., C. breviclava Mottern, n.sp ., C. brevisensillum Mottern n.sp ., C. curvigladius Mottern, n.sp ., C. longiseta Mottern, n.sp ., C. multisensillum Mottern n.sp ., C. noyesi Mottern, n.sp ., C. parvigladius Mottern, n.sp . and C. rosei Mottern, n.sp . Species are delimited based on a combination of morphological and molecular data (28S‐D2 rDNA and COI). Additional specimens are included in the phylogenetic analyses and although these likely represent several new species, we lack sufficient specimen sampling to describe them at this time. Cales are highly morphologically conserved and character‐poor, resulting in several cryptic species. A molecular phylogeny of the known Neotropical species based on 28S‐D2–5 rDNA and a 390‐bp segment of COI is included, and identification keys to males and females are provided. This published work has been registered in ZooBank, http://zoobank.org/urn:lsid:zoobank.org:pub:7FEB0479‐9B2E‐48E8‐8603‐4B7C2759D4EC .     

Titimbera,a new genus of Orthocladiinae from South and Central America (Diptera: Chironomidae)

Titimbera n. gen. is erected based on the males of three new species from South and Central America: T. amazonica n. sp. from the Amazon region, Brazil; T. titi n. sp. from Venezuela and T. laselvensis n. sp. from Costa Rica. The combination of bare eyes and wing membrane; antenna without strong apical seta; scalpellate acrostichals in mid scutum; costa strongly extended; R₄₊₅ ending opposite to M₃₊₄; Cu₁ strongly curved to slightly sinuous; anal point sitting high on tergite IX, nearly parallel-sided with bluntly rounded apex; and club-shaped to subtriangular gonostylus with distinct heel will separate the genus from all other orthoclads.     

A new genus and two new species of chigger mites (Acari: Trombiculidae) from the Laotian rock-rat Laonastes aenigmamus Jenkins, Kilpatrick, Robinson & Timmins (Rodentia: Diatomyidae)

A new chigger mite genus Laotrombicula n. g. and two new species, Laotrombicula khunboromi n. sp. (type-species) and L. fangumi n. sp., are described from the Laotian rock-rat Laonastes aenigmamus Jenkins, Kilpatrick, Robinson & Timmins (Rodentia: Diatomyidae). The new genus is most similar to Trombiculindus Radford, 1948 and Leptotrombidium Nagayo, Miyagawa, Mitamura & Imamura, 1916 and differs from these genera by having the scutum of subhexagonal or semicircular shape vs widely rectangular; pinnatifid dorsocentral idiosomal setae vs foliaceous in Trombiculindus and unexpanded in Leptotrombidium; and by the presence of serrated longitudinal crests in the middle part of scutum.     

A new species of entomopathogenic nematode Oscheius safricana n. sp. (Nematoda: Rhabditidae) from South Africa

In a recent entomopathogenic nematode (EPN) survey in the North West province of South Africa, Oscheius safricana was isolated from soil samples using the Galleria mellonella bait method. Morphological studies using light microscopy and scanning electron microscopy, molecular analysis of the internal transcribed spacer region (ITS), D2\D3 expansion segments of the large subunit rDNA gene (LSU) and concise small subunit rDNA gene (SSU), revealed that it was a new species, described herein as Oscheius safricana n. sp. Oscheius safricana n. sp. was characterised by unique ribosomal DNA sequences, amphidelphic reproduction, six separate lips each two bristle-like sensillae, narrow pharynx, valvated basal bulb, lateral field with four lines, leptoderan and closed bursa and fused spicules. This EPN belongs to the group Insectivorus and is morphologically closest to O. necromenus, O. chongmingensis and O. carolinensis. Oscheius safricana n. sp. is symbiotically associated with Serratia marcescens strain MCB.

A walking stick,Clonistria dominicana n. sp. (Phasmatodea: Diapheromeridae) in Dominican amber

A walking stick, Clonistria dominicana n. sp. (Phasmatodea: Diapheromeridae: Diapheromerinae: Diapheromerini) is described from Dominican amber. The new species can be distinguished from extant members of the genus by the long hind leg tarsomere II (over six times the length of the foreleg tarsomere II), the short metanotum, which is only half the length of the median segment and the prominent median carina. Two phasmatid eggs in separate pieces of Dominican amber are also presented. One of these has characteristics of the genus Clonistria Stål, 1875, which supports the generic placement of C. dominicana. The second egg resembles those of the genus Malacomorpha Rehn, 1906 (Pseudophasmatidae: Pseudophasmatinae). Both of these genera occur in Hispaniola today.     

Role of genital sex pheromones inAmblyomma americanum andA. maculatum (Acari: Ixodidae)

Amblyomma americanum andA. maculatum were studied to determine if genital sex pheromones were present, as reported inDermacentor species. Chemical analysis of methanol extracts of the anterior reproductive tracts (source of the genital sex pheromone) ofA. americanum andA. maculatum confirmed the presence of the same fatty acids that act as components of the genital sex pheromone inDermacentor variabilis andD. andersoni. In bothAmblyomma species, removal of the anterior reproductive-tract of fed females eliminated the male copulatory response. ForA. americanum, use of anterior reproductive tract extracts made with water, methanol, ether and hexane elicited significant probing and copulatory responses by conspecific males. However, inA. maculatum, use of anterior reproductive-tract extracts made with water, methanol, ether, chloroform: methanol (41), hexane and pentane did not restore mating response by males. Treatment with known components ofDermacentor genital sex pheromones elicited weak but significant responses inA. americanum, but did not restore male mating responses inA. maculatum. These results indicate that genital sex pheromones exist inA. americanum and are not restricted to the genusDermacentor. Characteristics of theAmblyomma genital sex pheromone, however, do differ considerably from those inDermacentor. No genital sex pheromone was present inA. maculatum.     

Two new Mallinella species from southern China (Araneae,Zodariidae)

Two new species of the spider genus Mallinella Strand, 1906 are reported from China: Mallinella sphaerica sp. n. (male, female) from Tianmu Mountain, Zhejiang Province and Mallinella pluma sp. n. (male) from Daming Mountain, Guangxi Zhuang Autonomous Region.     

Five new monogenean species from the gills of Mulloidichthys vanicolensis (Perciformes: Mullidae) off New Caledonia, with the proposal of Volsellituba n. g. and Pennulituba n. g. (Monogenea: Dactylogyridae)

Three species of Volsellituba n. g. and two species of Pennulituba n. g. are described from the gills of the yellowfin goatfish Mulloidichthys vanicolensis (Valenciennes) off New Caledonia (South Pacific). Volsellituba and Pennulituba resemble dactylogyrid genera whose species lack eye-spots and possess tandem or slightly overlapping gonads, a single prostatic reservoir, a male copulatory organ without an accessory piece, a dextroventral non-sclerotised vagina, ventral and dorsal anchor/bar complexes, and hooks with shanks comprising a single slender unit. Volsellituba n. g. is characterised by its species having ventral tegumental folds at the level of the vaginal duct, a male copulatory organ with a subterminal basal opening and a two-piece dorsal bar. The following new species of Volsellituba are described: V. orchidea n. sp. (type-species), V. nabla n. sp. and V. elephantina n. sp. Pennulituba n. g. is distinguished by its species possessing a male copulatory organ with a wing-shaped membrane and a dorsal bar with a poorly to non-sclerotised medial part. This genus includes P. piratifalx n. sp. (type-species) and P. cymansis n. sp. A tabular summary of the species of Haliotrema Johnston & Tiegs, 1922 reported from mullids is provided.     

Mitogenomic phylogenetics of Diochus occultus n. sp., a palaeoendemic endogean species within the tribe Diochini (Coleoptera: Staphylinidae: Staphylininae)

The tribe Diochini has a worldwide distribution, with 2 and 74 epigean species within the genera Antarctothius and Diochus, respectively. Recent phylogenetic studies suggest a sister relationship of Diochini and a lineage formed by Xantholinini, Maorothiini, and Othiini, within the subfamily Staphylininae. Here, we describe the first known endogean representative of Diochini, Diochus occultus n. sp., and provide the first two complete mitogenomes for the tribe, corresponding to the two European Diochus species: Diochus occultus n. sp. and Diochus staudingeri. These sequences were combined with 40 additional mitogenomes from representatives within Staphylininae, Paederinae, Silphidae, and Aleocharinae, and COI sequences from 5 additional species of Diochus to conduct a series of mitogenomic phylogenetic and dating analyses. The estimated molecular phylogeny is fully consistent with previous studies based on morphology and molecular data, finding a sister relationship of Diochini with a clade formed by Xantholinini and Othiini (Maorothiini not sampled). Dating analyses inferred an early split of the tribe Diochini at 140–156 Mya. Morphology shows clear differences in the aedeagal and external morphology of D. occultus n. sp. and D. staudingeri, whereas a sister relationship of these taxa is found in the phylogenetic analyses, with the split dated at 48–61 Mya. Although the study of additional Palaearctic Diochus species will be required to conclusively establish that D. occultus n. sp. is a palaeoendemic taxon sister to D. staudingeri, associated with forests of Abies pinsapo in the south of the Iberian Peninsula, this conclusion is consistent with the ancient estimated age of speciation, endogean habitat specificity, low dispersal capacity (flightless species), and microendemicity of D. occultus. This is also consistent with the continued emersion of the Betic sub‐plate along its tectonic evolution. The estimated ages of diversification of the Paederinae‐Staphylininae lineage are also discussed.
