Cletus saucius Stål, 1873: 78.
Redescription. Male. Head length 1.30; width across eyes 1.56; interocular space 0.78; interocellar space 0.36; preocular distance 0.66; antennal segment length I, 1.92, II, 1.88, III, 1.60, IV 1.80; pronotum length 2.20; width across humeral angles 5.00; scutellar length 1.48; width 1.52; maximum width of abdomen 3.72; total body length 10.40. Dorsal coloration.— General color dark yellowish orange, punctures reddish brown; head with black narrow longitudinal stripe behind eyes; antennal segments I to IV pale reddish orange, with yellowish white granules; scutellum, clavus, corium, densely suffused with pink marks; middle third of pronotal disk with complete yellowish orange longitudinal stripe; anterolateral and posterolateral borders of pronotum with creamy white teeth; spine of humeral angle dark yellowish orange to shiny dark brown; apex of scutellum pale yellow; hemelytral membrane dark yellow, basal angle dark brown; connexival segments III to VI dark yellow, upper border pale yellow, punctures reddish brown, and VII pale reddish orange, upper border pale yellow, punctures reddish brown; dorsal abdominal segments III to VI shiny yellowish orange, VII shiny reddish orange. Ventral coloration.— Pale yellow, suffused or not with pink marks, following dark brown to black: apex of rostral segment IV, punctures, broad spot on abdominal sternite II, six rows of small to medium-sized discoidal spots on abdominal sterna III to VII; anterior and posterior lobe of metathoracic peritreme yellow; coxae yellow with two black discoidal spots; trochanter dark yellow; femora dark yellow with dark brown discoidal or irregular spots; tibiae yellowish orange, apical third shiny reddish orange; tarsi shiny reddish orange. Structure.— Head.— Antennal segment I uniformly stout, wider, granulate, segments II and III barely robust, cylindrical, and IV fusiform, and elongate; segments I>II>IV>III; antenniferous tubercles widely separate, outer border armed with one short acute spine; rostrum reaching posterior border of mesosternum, or anterior third of metasternum (Fig. 12). Thorax.— Pronotum.— Humeral angle tapering into large acute spine, directed outward and slightly backward (Fig. 8). Legs.— Femora and tibiae granulate. Genital capsule.— Posteroventral edge with lateral angles straight, without expansions, mesally relatively elongate, mesial lobe wide, protruding, obtusely rounded at apex, and with weakly inflexed at center (Fig. 22).
Female. Head length 1.24; width across eyes 1.58; interocular space 0.82; interocellar space 0.38; preocular distance 0.70; antennal segment length I, 2.00, II, 2.00, III, 1.60, IV 1.96; pronotum length 2.10; width across humeral angles 5.04; scutellar length 1.48; width 1.56; maximum width of abdomen 3.72; total body length 10.37. Coloration similar to male. Connexival segments VIII and IX and dorsal abdominal segments VIII and IX shiny yellowish orange; genital plates pale yellow. Structure.— Head: antennal segment I longest or equal than II, and III shorter than IV.
Variation. 1. Ventral surface of body pale yellow, densely suffused with pale shiny reddish orange marks. 2. Apical margin and apical angle of corium reddish. 3. Costa border of corium with yellowish white teeth. 4. Tibiae pale yellow, apical third reddish, and 2 or 3 dark brown rings, these sometimes hard to see. 5. Middle third of abdominal sterna III to VII with irregular black longitudinal stripe.
Type locality. N AUSTRALIA (as Australia Borealis).
Distribution. AUSTRALIA: New South Wales: Gayndah, and SE coastal; Queensland, NE coastal. (Blőte 1935, and Cassis and Gross 2002).
Material examined. New records. AUSTRALIA: 1 male, New South Wales, Bellinger River, 3 km W Thora, 12-I-1990, B. y M. Baher (ZSMC); 1 male, 1 female, Queensland, Brisbane, 3-VII-1911, 20-IV-1912, H. Hacker (BMNH); 1 female, SE Queensland, Mt. Maroon, S. Rathdownes, 27-I-1973, M. Baher (ZSMC); 1 female, Queensland, Broken R, Eungella, 8-XII-1961, McAlpine and Lossin (AMUS); 1 male, Queensland, Edge Hill, NW of Cairns, 6-IX-1969, J. E. Tobler (UNAM); 1 male, 2 females, Queensland, Baldwin Swamp, E of Bundaberg, 31-X-1977, 2–19-XI-1977, H. Frauca (ANIC); 1 male, New South Wales, Hawkesbury Reserve, 19-VII-1980, R. Patterson (ANIC).
Comments. This species is recognized by having outer border of antenniferous tubercles armed, humeral angle of pronotum tapering into large acute spine directed outward, and slightly backward (Fig. 8), apical third of tibiae and tarsi shiny reddish, and by the shape of the posteroventral edge of male genital capsule (Fig. 22).
Additionally in C. saucius Stål (1873) the apical edge of the corium lacks an ivory to whitish discoidal spot, and the anterior half of pronotal disk, as well as the propleuron, mesopleuron, and metapleuron, lack a black discoidal spot
In C. minutus Blöte (1935) and C. similis Bl öte (1935) the antenniferous tubercles are unarmed, the humeral angles obtuse or subacute (Figs. 7, 9), the apical edge of corium has an ivory to whitish discoidal spot, and the anterior half of pronotal disk, as well as the propleuron (sometimes hard to see to absent), mesopleuron, and metapleuron each has a black discoidal spot.
