Rhinomiriella Gorczyca, 2001: 416 (type species R h i n o m i r i e l l a t u b e r c u l a t a G o r c z y c a, 2 0 0 1 b y monotypy); Gorczyca, 2006: 74 (catalogue).

Diagnosis

Head longer than high in lateral view, not carinate posteriorly ( Figs 16B, 18C); body impunctate; antenna subequal to or shorter than body length ( Fig. 5); collar present ( Figs 16A, 18B); labial segments I and II subdivided with suture ( Figs 16H, I, 18E, F); calli upraised and conical ( Figs 16B, 18C); evaporatorium triangular and occupying half of metapleuron ( Figs 16J, 18J); cuneus delimited ( Figs 16J, 18O); hind tarsus three-segmented, tarsal segment I twice as long as segments II and III combined ( Figs 16K, 18N).

Redescription: male

Coloration: Mostly pale brown to brown with yellow markings.

Surface and vestiture: Dorsum matte, impunctate, covered with simple setae; meso- and metapleuron covered with microsetae forming net-like ornament ( Figs 16J, 18J) (see also species description).

Structure: Head. In dorsal view, eye slightly removed from pronotum, vertex wider than eye diameter, not carinate ( Figs 16A, 18B); in anterior view, head wider than high, antennal fossa attached near ventral margin of eye, clypeus not separated from frons, its base placed higher than antennal fossa ( Figs 16C, 18A); in lateral view, head distinctly longer than high, distance between eye and ventral margin of head distinct, shorter than half of eye height, antennal fossa placed directly behind suture between mandibular and maxillary plate, removed from eye at a distance subequal to antennal fossa diameter; buccula extending slightly behind antennal fossa; distance between buccula and pronotum longer than buccula length ( Figs 16B, 18C). Antenna ( Figs 16G, 18H). Subequal to or shorter than body length; segment I slightly wider or same width as segment II, segments III and IV slightly thinner than segment II; segments I and II not incrassate. Labium ( Figs 16F, H, I, 18D–F). Extending to segments VI–VII or genital segments; segments I and II subdivided apically. Thorax. Collar delimited with distinct suture, shallow medially; lateral margins of pronotum carinate, slightly upraised, callosite area distinctly upraised, subdivided into two cone-shaped lobes by longitudinal sulcus medially ( Figs 16A, B, 18B, C); mesoscutum exposed ( Figs 16A, 18G); propleural suture T-shaped ( Figs 16B, 18C); mesepimeral apodeme slit-like, metathoracic spiracle narrow, open, with microsculpture along anterior margin, metathoracic gland evaporative area subtriangular, peritreme upraised, rounded, metepimeron narrow ( Figs 16J, 18J). Hemelytron ( Figs 16D, E, 18G, O). Clavus with longitudinal upraising; claval commissure distinctly longer than scutellum, medial fracture distinct, reaching middle of corium; cuneus delimited with indistinct suture, not notched. Legs. Coxae elongate, longer than pleura height, forecoxae longer and wider than other coxae; fore- and hind femora widened, forefemur slightly wider and shorter than hind femur, middle femur distinctly narrower and subequal in length to forefemur ( Figs 16F, J, 18I–L); segment I distinctly longer than segments II and III each ( Figs 16K, 18N); claw with subapical tooth ( Figs 16L, 18M, P). Genitalia. Endosoma subdivided into vesica and conjunctiva sensu Kerzhner & Konstantinov (1999), vesica with two long sclerites, secondary gonopore with microsculpture ( Figs 17A–C, 19A–C). See species descriptions for more details.

Redescription: female

Similar to male, body generally larger and vertex wider (see species description for measurements). Genitalia (see description for Rhinomiriella tuberculata ).

Remarks

This genus is known only from Australia. It has been collected in coastal and inland New South Wales and Queensland and in coastal localities of Victoria, South Australia and Western Australia ( Fig. 25) .

Remarks

Gorczyca (2001) described Rhinomiriella to accommodate his new species Rhinomiriella tuberculata . He placed it in the tribe Rhinomirini based on the long antennal segments III and IV, which are longer than segments I and II, the long labium and long tarsal segment I. Gorczyca (2001) also established the Rhinomiriella complex to accommodate this genus. We obtained molecular data for Rhinomiriella sp. from Western Australia, which is similar to Rhinomiriella aidani externally. Our phylogenetic analyses showed that Rhinomiriella is not closely related to other members of the Rhinomirini , but is nested in Fulviini s.s. with other Australian species of Lygaeoscytus , Peritropisca and Xenocylapidius , with high support ( Figs 1–3). However, to make a definitive conclusion on the phylogenetic position of Rhinomiriella , broader taxon sampling of the Fulviini is required. There are more species of Rhinomiriella in Australia, but they all are represented by singletons. We regard the use of the Rhinomiriella complex as an informal group as unnecessary.
