A new genus, Perplexacara, and new generic placements of species of Australian marsh beetles (Coleoptera: Scirtidae) based on morphology and molecular genetic data
No full textThe Australian Scirtidae species previously identified as misplaced in the widespread genus Prionocyphon Redtenbacher are revisited as well as their possible relationship with the Australian genus Macrodascillus (Lea) using sequence data from the mitochondrial gene, cytochrome oxidase subunit 1 and two nuclear genes, elongation factor 1-alpha and Topoisomerase. The study confirmed the conclusion of Cooper et al. (2014) that the species did not belong in Prionocyphon. The study also included a species from each of three possibly related genera, Chameloscyphon Watts, Daploeuros Watts and Dasyscyphon Watts. Chameloscyphon huonensis Watts, Dasyscyphon victoriaensis Watts and Daploeuros lamingtonensis Watts were recovered as separate lineages with C. huonensis linking with Das. victoriaensis and Dap. lamingtonensis isolated. The species previously included in Prionocyphon were shown to belong in two genera, Macrodascillus and a new genus Perplexacara: Perplexacara caementum (Watts) new combination, P. latusmandibulara (Watts) new combination, P. macroflavida (Watts) new combination, Macrodascillus scalaris (Lea), M. insolitus (Watts) new combination and M. lamingtonensis (Watts) new combination.C.H.S.

Eurycyphon aquilus Watts 2011
No full textEurycyphon aquilus Watts, 2011 (Fig. 51) Material studied. 2 ♂ Vic, Cement Creek beating vegetation 2 / 2 /08 CHS Watts (SAMA, PZ). Male (Fig. 51). The base of the tegmen is more rounded than in the relatives. The parameres are distally not convoluted but divided into a ventral and a dorsal branch. Each ventral branch ends in an approximately triangular sclerite which is directed mediad and opposed to its counterpart. The dorsal branch is longer and ends in an elongate plate which in oblique view is seen to have a ventrally bulging serrate edge. The dorsal paramere branch also bears a sinuous thin sclerite directed mediad and cephalad. The sides of the pala are straight and diverge towards the wide weakly sclerotized front. The tip of the parallel trigonium is shallowly excised, the corners are blunt, in the middle of the notch a small triangle projects ventrally. The parameroids resemble those of the relatives. Note. The males studied here were taken together with syntypes but are inadvertantly left over material without type status (personal communication C.H.S. Watts).Published as part of Zwick, Peter, 2015, Australian Marsh Beetles (Coleoptera: Scirtidae). 8.

Hendrich & Watts des. 2009” [red label, printed] (CLH).</p> <p> <b>Etymology</b>. Named after the Kalbarri National Park where part of the type material was collected.</p> <p> <b>Description</b>. Measurements. TL = 3.6–3.8 mm (holotype 3.8 mm); TL-H = 3.3–3.5mm (holotype 3.5 mm); MW = 1.95–2.05 mm (holotype 2.0 mm).</p> <p> <b>Colour</b>. Upper side yellowish-brown; portions of elytron and sutural lines a bit darker, sutural lines broadly bordered with broad pale strip, apical portions lighter (Fig. 2). Venter yellowish, including pronotum, epipleuron, metaventrite, metacoxal plate, prosternal process, legs and abdominal sternites. All antennomeres completely pale yellowish.</p> <p> <b>Sculpture</b>. Dorsal surface strongly, densely and evenly punctured throughout; those on head weaker and sparser, a little smaller than eye facet. Pronotum and elytron with narrow but well marked lateral beading. Microreticulation on head and pronotum fine, moderately impressed, on elytron very fine and almost unvisible. Ventral surface; punctures very dense, microreticulation similar to that on elytron. Prosternal process narrowly lanceolate, rounded tip, almost keeled in cross section, slightly narrowed between procoxae. Metacoxal lines raised, moderately separated, subparallel in posterior half, diverging to about twice their narrowest width in anterior half.</p> <p> <b>Male</b>. Protarsi moderately expanded, robust; single proclaw thickened, strongly bent near base, continously narrowing to sharp point at apex, with slightly curved large tooth at base (Fig. 5). Mesotibia robust, broadly but weakly indented on inner side in middle. Seta tufts on mesotrochanters somewhat thicker than on female. Median lobe of aedeagus in lateral view rather thin, elongated, in ventral view symmetric tapering towards tip (Fig. 4).</p> <p> <b>Female</b>. Pro- and mesotarsi narrower than in males, not expanded. Proclaws simple. Mesotibia narrow.</p> <p> <b>Affinities</b>. The new species appears closest to <i>A. bakewellii</i>, <i>A. jenniferae</i> and <i>A. simplex</i>. From <i>A. bakewellii</i> (TL = 3.1–3.45 mm) (Figs 1, 3) it differs by its larger size, less marked and more diffuse elytral colour pattern, the more parallel sided and elongated form of the median lobe, and the robust and well developed spine at the base of the claw on the male protarsi (compare Watts 1978: 65 and Watts 1997: 39). From the smaller <i>A. jenniferae</i> (TL = 3.4–3.6 mm) it can be distinguished by its yellowish tarsi (totally black in <i>A. jenniferae</i>), and the form of the aedeagus which is slender and tapering to the tip in <i>A. kalbarriensis</i> <b>sp.n.</b>. From the slightly smaller (TL = 3.5–3.7 mm) <i>A. simplex</i> Watts, 1978 from Queensland, <i>A. kalbarriensis</i> <b>sp.n.</b> can be well separated by its more elongated median lobe of aedeagus, which is more tapered at the tip, and its larger and more robust spine at the base of the claw on the male protarsi as well as a stronger dorsal colour pattern which is virtually absent in <i>A. simplex</i> (compare Watts 1978: 65 and Watts 1997: 39). In the key given in Watts 1997 the species will run to couplet 7.</p> <p> <b>Distribution</b>. Western Australia, Murchison District. Only known from two localities along the Murchison River (Fig. 6).</p> <p> <b>Habitat</b>. At both localities the specimens were collected from half-shaded (sedges at the banks), shallow, sandy backwater pools, with dense mats of Chara and other floating vegetation, beside the Murchison River (Fig. 7). The bottom consisted of fine sand with a thin layer of mud and plant debris (Fig. 8).

New genera, species and combinations in the Pseudomicrocara Armstrong group (Coleoptera: Scirtidae) based on morphology supported by mitochondrial and nuclear gene sequence data
No full textThe Australian Scirtidae genus Pseudomicrocara Armstrong, previously shown to be polyphyletic, is revised using both morphology and sequence data from the mitochondrial gene cytochrome oxidase subunit 1 and two nuclear genes, elongation factor 1-alpha and topoisomerase. Twenty-three genera, 16 of which are new, are recognised based on morphology, primarily of the mandibles and maxillary palpi, and male and female genitalia. Maximum likelihood and Bayesian phylogenetic analyses were used to examine relationships among species from 21 of the 23 recognised genera. Fifteen of the genera were recovered as distinct lineages. A further six, Accolabass Watts, Anocyphon gen. nov., Copiacyphon gen. nov., Nasutuscyphon gen. nov., Pseudomicrocara and Saprocyphon gen. nov. were considered to be genera based on both morphology and phylogenetic analysis but their species composition is uncertain and will require more work to confirm. The 17 new genera are fully described, keys are provided to all the genera in the Pseudomicrocara group, and to all the species in the genera Copiacyphon gen. nov., Spilotocyphon gen. nov., Accolabass Watts, Saltuscyphon gen. nov. and Vadumcyphon gen. nov. The male aedeagi of all new genera and species are illustrated, as are the female prehensors of some species. The following genera are described as new: Alpestriscyphon gen. nov., Anthocara gen. nov., Anocyphon gen. nov., Copiacyphon gen. nov., Furcacyphon gen. nov., Latuscara gen. nov., Pictacara gen. nov., Nasutuscyphon gen. nov., Nektriscyphon gen. nov., Pumiliocara gen. nov., Ruborcara gen. nov., Saltuscyphon gen. nov., Saprocyphon gen. nov., Sisyracyphon gen. nov., Spilotocyphon gen. nov., Tenebriocyphon gen. nov. and Vadumcyphon gen. nov. A total of 45 new combinations are proposed. The following species are described as new: Accolabass monteithi sp. nov.; Alpestriscyphon bartlefrere sp. nov., Al. spurgeon sp. nov.; Anocyphon lepus sp. nov.; Copiacyphon brindaleensis sp. nov., C. cardinalis sp. nov., C. dytikos sp. nov.; Pumiliocara peneparva sp. nov.; Ruborcara saintae sp. nov.; Saltuscyphon montanus sp. nov., Sal. teraniaensis sp. nov.; Saprocyphon bithongensis sp. nov.; Sisyracyphon brisbanensis sp. nov., S. bulburinensis sp. nov.; Spilotocyphon occidentalis sp. nov., Sp. orientalis sp. nov., Sp. zwicki sp. nov.; Vadumcyphon centralis sp. nov., V. rugosus sp. nov. A checklist of all Australian taxa in the redefined Pseudomicrocara group is included. Sequence data of the Argentinian species Pseudomicrocara antarctica (Fairmaire) is included. Phylogenetic analyses place this species as a distinct lineage within the Pseudomicrocara group.C.H.S. Watts, S.J.B. Cooper, M.L. Libonatt

A COLLECTION OF TICKS (IXODIDAE) FROM SULAWESI UTARA, INDONESIA
No full textIxodid ticks were collected from seven species of endemic murid rodents and from vegetation in Sulawesi Utara, Indonesia. Adult ticks belonging to the species, Amblyomma babirussae, A. cyprium and Dermacentor (Indocentor) steini were taken from the vegetation. Immature ticks assignable to the genera, Haemaphysalis, Amblyomma and Ixodes infested the murids with Parauromys dominator and Maxomys musschenbroekii being the two most heavily tick-infested host species. The data are compared to other tick records from Sulawesi
