Austrothelphusa wasselli Naser & Davie & Waltham 2018
No full textAustrothelphusa wasselli species-complex Diagnosis. Carapace broadly oval, moderately convex; surface medially punctate; gastro-cardiac (H-shaped) grooves present but not strongly marked; epigastric regions separated by median groove; epigastric crests absent or poorly developed; postorbital crests low or absent; branchial regions not markedly swollen, lacking anterolateral striations, punctate; cervical grooves shallow, poorly marked; anterolateral margins smoothly cristate, evenly convex, with one, more or less distinct, but always small epibranchial tooth. Frontal and orbital margins with raised rim. Exorbital angle spine moderately blunt. Posterolateral borders straight, convergent posteriorly, bearing oblique striations. Front more or less bilobed. Male pleon broadly triangular; somites 4 and 5 strongly tapering; somite 6 slightly tapering; telson length subequal to breadth at base, tongue-shaped. Small species, typically less than 25 mm maximum carapace width; females with mature pleon by 13 mm CW. Remarks. Justification for using the term “species-complex” to treat a group of samples from various river catchments from across Cape York, is given elsewhere in this paper, and will not be repeated here. Suffice to say that we have found discrete morphological patterns within the broad geographic range currently ascribed to A. wasselli sensu lato, and these differences are supported by significant genetic divergence. It is intended to describe a number of further new species as a result of our ongoing study exploring the phylogeny of this group using both mitochondrial and nuclear genetic markers. The members of the A. wasselli species-complex are easily recognisable from other Austrothelphusa species by: the relatively unswollen anterolateral branchial regions that lack obvious oblique striations; the telson of the male pleon being about as long as wide at base; and the small size when fully grown, especially the small size of females at sexual maturity. Based on pleon shape, A. wasselli sensu lato is closest to A. raceki (Bishop 1963: fig. 2A). Preliminary unpublished genetic results (P.J.F. Davie & D. Gopurenko) also indicate that A. raceki samples form the sister clade to A. wasselli sensu lato.Published as part of Naser, Murtada D., Davie, Peter J.

Nathan Newsom diary
No full textNarrative account entitled "A Short summary of a journey, taken by volunteers from Gallia County; for the purpose of destroying Indians and the invasion of Canada," written by Nathan Newsom. Newsom was an orderly sergeant in Captain Calvin Shepard's company from Gallia County, Ohio, during the War of 1812. This volume conveys conditions experienced by soldiers during the war, including low pay, shortages of food and clothing, low morale, and severe weather conditions. Newsom also describes the cooperation of the army with friendly Indians and the disciplinary measures taken for desertion and other offenses
Austrothelphusa gilbertensis Naser & Davie & Waltham 2018, sp. nov.

HOLOTYPE: QM-W28346, male (22.3 × 17.6 mm), Venture Creek, E of Croydon, Gilbert Catchment, Queensland, J. & S. Hasenpusch, 0 1.05.2006. Paratypes: QM-W28040, 3 males (23.0 × 18.1, 22.9 × 18.1, 19.9 × 15.6 mm), 8 females (24.3 × 19.1, 24.3 × 19.1, 23.5 × 18.5, 22.6 × 17.9, 22.0 × 17.2, 19.8 × 15.6, 21.4 × 16.8, 18.4 × 14.5 mm), same data as holotype. QM-W28339, male (20.5 × 16.1 mm), small creek off Gilbert River, coll. Nathan Waltham, 9.05.2014. QM-W28305, female (16.0 × 12.6 mm), Pleasant Creek, off Gilbert River, coll. S. Hedge & J. Sariman, 0 3.04.2007. Description. Small species (maximum CW of present material, female 24.3 mm). Carapace of mature specimens broadly oval (Fig. 8A), c. 1.27 times broader than long (range 1.26–1.28, n = 14). Front projecting beyond level of exorbital angles, prominently bilobed, medial concavity relatively deep; inner part of orbital cup poorly defined, merging broadly with lateral slope of frontal lobe (Fig. 7B). Frontal and orbital margins with raised rounded rims. Postfrontal (epigastric) lobes moderately well developed, bearing distinct striated ridges; separated by deep narrow groove. Postorbital region moderately depressed, short slightly convex crest laterally adjacent to, but not quite reaching, epibranchial tooth. Anterolateral margins smoothly cristate, evenly convex, distinct but small epibranchial tooth (relatively more prominent than in A. wasselli). Branchial regions moderately but not markedly swollen, bearing punctations; anteriorly lacking striations but with striated ridges posterolaterally. Cervical groove shallow, relatively well defined, deeper than in A. wasselli); gastro-cardiac (H-shaped) grooves relatively well defined. Posterolateral borders straight, convergent posteriorly. Male pleon (Fig. 6F, 8B, 10C) broadly triangular; telson tapering, apically rounded, length subequal to breadth at base. Somite 6 slightly tapering (proximal width 1.26 times distal width), c. 1.38 times wider at base than long; with a pair of slightly raised transverse rounded crests distomedially. Somite 5 more strongly tapering (proximal width 1.54 times distal width), c. 2.75 times wider at base than long. Somite 4 also strongly tapering (proximal width 1.57 times distal width), c. 4.3 times wider at base than long. Somites 2 and 3 broad, with lateral margins evenly rounded, narrow. Walking legs moderately long, total length of P5 (basis to tip of dactyl) c. 1.1 times maximum carapace width. P5 (Fig. 7D): merus with anterior and posterior borders diverging distally, relatively straight, 3.11 times longer than wide; propodus short, anterior border only weakly convex, 2.07 times longer than wide; dactylus short, slightly longer than propodus (1.12 times). G1 (Fig. 7G, H) short, broad basally but tapering and slender over distal half, markedly curved inward apically. Outer lateral margin (in sternal view) broadly concave through medial third, before curving inwards towards apex. Terminal opening small, elongate V-shaped, apical flanges smoothly tapering. Some sparse long simple setae along inner margin towards tip. Colour. Dorsal surfaces of fresh and recently preserved material are grey to yellowish-green; a scattering of well separated, small, but obvious and discrete red dots across the dorsal surfaces of the carapace, walking legs and claws. Ventral surfaces generally pale yellow. Frontal face of chelae pale yellow with an oblique broad band of orange behind the gape; tips of fingers orange (Fig. 10). Distribution and ecology. Only known from a restricted area in the central region of the Gilbert River Catchment (Fig. 1), but further collecting will presumably find it to be more widespread within the catchment. Found in freshwater pools, and at the edge of small creeks, on clay and firm mud substrates; often under leaves. Etymology. The species is named for its Gilbert River type locality. Remarks. As already discussed the COI barcoding region for Austrothelphusa gilbertensis sp. nov. shows it to be genetically distinct from A. wasselli by 5.4–6.4% (also see further comment in the Discussion). Careful examination also shows a number of significant morphological differences that can be used to easily separate the two species: Austrothelphusa gilbertensis sp. nov. differs from A. wasselli by: 1) having relatively more prominent epibranchial teeth; 2) the front has a relatively deep medial concavity (Fig. 7B), versus much shallower in A. wasselli (Fig. 7A); 3) the inner part of the orbital cup is poorly defined, broadly merging with the lateral slope of the frontal lobe (Fig. 7B), whereas in A. wasselli the inner part of the orbital cup is moderately well-defined, merging quite steeply with the lateral slope of the frontal lobe (Fig. 7A); 4) the postfrontal (epigastric) lobes are moderately well developed, bearing distinct striated ridges, versus not well developed, and lacking striated crests in A. wasselli; 5) the cervical groove is relatively well defined, and deeper than in A. wasselli; 6) the gastro-cardiac (H-shaped) grooves are relatively well defined, versus shallower and less defined in A. wasselli; 7) somite 6 of the male pleon is c. 1.38 times wider at the base than long, versus c. 1.64 times in A. wasselli; and bears a pair of slightly raised transverse rounded crests distomedially (Fig. 9C) that are lacking in A. wasselli; 8) somite 5 of the male pleon is c. 2.75 times wider at base than long, versus c. 2.97 times in A. wasselli; 9) the merus of P5 has the anterior and posterior borders diverging distally, relatively straight, and 3.11 times longer than wide (Fig. 6D), versus anterior and posterior borders subparallel, slightly convex, and only 2.77 times longer than wide in A. wasselli (Fig. 6C); 10) the G1 is markedly curved inward apically, with the outer lateral margin (in sternal view) broadly concave through the medial third (Fig. 7G), versus moderately curved inward apically, and outer lateral margin relatively straight over the basal two-thirds in A. wasselli (Fig. 7E); and finally, 11) the live colour patterns differ— A. gilbertensis has obvious small well-spaced dark spots across the anterolateral and medial parts of the carapace (Fig. 10), whereas A. wasselli has more of a speckling of fine small red dots, across the anterolateral half of the carapace.Published as part of Naser, Murtada D., Davie, Peter J.
