Goniagnathus crocodontis Fletcher, sp.nov.
No full textGoniagnathus crocodontis Fletcher sp.nov. (Figures 3, 9, 35–39) Holotype: male, Sth Alligator Inn, NT, 12.40 S 132.30 E. 7–9.vii. 1979, G. Monteith and D. Cook, m. v. light (QM) Paratype: Northern Territory: male, same data as holotype (QM) Colour: generally rich chocolate brown with light brown and cream speckling, lateral margin of pronotum cream extending onto tegmen as irregular cream flash, apical half of costal margin of tegmen and three round spots along hind margin also cream. Morphology: Brachypterous in known specimens. Length (estimate) 3.5 mm Male genitalia: Pygofer (Figure 35) rounded apically, bearing one or two macrosetae on posterodorsal margin. Subgenital plates (Figure 36) fused to form broadly quadrate plate, slightly emarginate medially. Parameres (Figure 37) with apical section very short, broad, finely rugose, shallowly sinuate apically; basal section broad laterally, narrow medially to articulation with connective. Aedeagus in lateral view (Figure 38) curving slightly anterodorsally, apically acute; in posterior view (Figure 39) broad-lanceolate with row of 10– 12 strong curved teeth laterally, apically shortly bifurcate to form pair of triangular processes beyond gonopore. Female: unknown. Etymology: The specific name is derived from dontis = tooth combined with an abbreviated “crocodile” and refers to the strongly toothed margin of the aedeagus and not the type locality. Notes: This is the most distinctively coloured species of Goniagnathus with the lateral flash of cream against the general chocolate brown colouring. The broad aedeagus margined with strong serrations is also quite distinctive. The length measurement given here is an estimate because both male specimens had the abdomen removed for genitalia examination prior to measurements being taken. This is the most northerly distributed species of Goniagnathus in Australia although a single specimen of G. pectinatus is known from N. Qld.Published as part of Fletcher, Murray J. & Zahniser, James N., 2008, The first record of Goniagnathini from Australia with description of four new species of Goniagnathus Fieber (Hemiptera: Cicadellidae: Deltocephalinae), pp. 43-54 in Zootaxa 1692 on page 50, DOI: 10.5281/zenodo.18061
Goniagnathus venenensis Fletcher, sp.nov.
No full textGoniagnathus venenensis Fletcher sp.nov. (Figures 2, 8, 29–34) Holotype: male, Poison Pt Plain, 20km W of Bourke, NSW, 26.ii. 1981, B.J. Loudon (ASCU: ASCTHE005914) Paratypes: New South Wales: 1 male, 1 female, 1 unknown (lacking abdomen) same data as holotype (ASCU); South Australia: 2 males, Keith 26.x. 2004, pit trap, SGSL project (ASCU) Colour: Pale testaceous to light brown, with sparse dark brown speckling. Morphology: Brachypterous. Length: Female (N= 2) 3.80–3.82 mm Male genitalia: Pygofer (Figure 29) roundly lobate, with oblique groove dividing basal section from apical lobate section which bears subapical biseriate row of macrosetae decreasing in length from dorsal to ventral. Ventral margin of lobe emarginate forming two ventral prominences. Subgenital plates (Figure 30) forming quadrate, transverse plate. Parameres (Figure 31) with apical section finely rugose, well sclerotised, short, broad and shallowly concave apically with outer lobe narrower than inner which is little more than angulate corner. Basal section transverse, narrowing towards articulation with connective. Aedeagus (Figures 32, 33) stout, parallel-sided, curved anterodorsally, bifurcate apically on anterodorsal side of apical gonopore. Female: Pregenital sternite (Figure 34) with hind margin sinuately emarginate, deeply triangularly excavate medially. Etymology: The species name is derived from the Greek for poison, reflecting the name of the type locality. Notes: All known specimens of this species are brachypterous. A size range is not given for males since the four males were all dissected prior to measurements being taken. In general size, males are comparable to the females.Published as part of Fletcher, Murray J. & Zahniser, James N., 2008, The first record of Goniagnathini from Australia with description of four new species of Goniagnathus Fieber (Hemiptera: Cicadellidae: Deltocephalinae), pp. 43-54 in Zootaxa 1692 on page 50, DOI: 10.5281/zenodo.18061
Distantasca smithi Fletcher & Donaldson 1992, n. comb.
No full textDistantasca smithi (Fletcher & Donaldson, 1992), n. comb. (Figs 1 –6, 25, 28, 31) Empoasca (Empoasca) smithi Fletcher & Donaldson, 1992: 183 –186 Type materials. Australia: holotype (examined): ♂, Queensland: Mundubbera, 1.iii. 1989, coll. D. Smith, ex Citrus (ASCU); paratypes (examined): 3 ♀♀, same data as holotype Distribution. Australia (Queensland). Note. The anal tube appendages of Distantasca smithi are well developed and the long and narrow subgenital plates have macrosetae reaching the tip of the plate (Figs 1–2). The setae of group group D are divided into two bands one near the mid-length of the plate and one just before the apex and are elongate and hairlike setae (Fig 1). This is a diagnostic feature of Distantasca and consequently this species is transferred from Empoasca (Empoasca) into the genus Distantasca. The narrow, constricted stem of the connective is also characteristic of Distantasca although it is narrower in D. smithi than in other known members of the genus.Published as part of Liu, Yang, Fletcher, Murray J. & Zhang, Ya-Lin, 2014, Reinstatement of Distantasca Dworakowska (Hemiptera: Cicadellidae: Typhlocybinae: Empoascini) as a valid genus with new species and new combinations in Zootaxa 3869 (1), DOI: 10.11646/zootaxa.3869.1.9, http://zenodo.org/record/23131

Koebele ” (BPBM). Description. Head and body (Figs 1, 2) pale testaceous with brown flecking. Vertex (Fig. 2) with indistinct, narrow, transverse band subapically which lacks brown flecking, occipital suture dark brown. Tegmen (Fig. 1) whitish with brown flecking, veins pale brown, claval suture sometimes yellowish. Genitalia. Male: Subgenital plate (Fig. 21B) tapering into apical finger-like process. Parameres (Fig. 21C) each with preapical lobe well developed; apical process with preapical tooth. Connective (Fig. 21E) long with arms about as long as stem. Aedeagal shafts in posterior aspect (Fig. 21F) broadly divergent at base and evenly curved dorsally and of even width to gonopore, bearing narrow, bifurcated apical process directed dorsomedially; in lateral view (Fig. 21D) curved basally, then more or less straight. Basal apodeme (Fig. 21D) short, blunt apically. Female: Apical margin of pregenital sternite (Fig. 31A) transverse with medial section extended slightly posteriorly and shallowly concave. Comments. This species was omitted from Knight’s (1970a) revision of the genus Hishimonus on the basis that he did not have representative material. It is possible, however, that he recognised that the species did not fit into the genus as he had defined it. The species is reasonably well represented in collections and distributed through much of coastal Queensland. It is frequently found on species of Melaleuca L. (Fam. Myrtaceae) which appear to be its natural host.Published as part of Fletcher, Murray J. & Dai, Wu, 2018, A new genus Austrimonus for Eutettix melaleucae Kirkaldy (Hemiptera: Cicadellidae: Deltocephalinae: Opsiini) and nine new species, pp. 310-330 in Zootaxa 4387 (2) on page 312, DOI: 10.11646/zootaxa.4387.2.4, http://zenodo.org/record/118746
