Introduction

This species name has had a rather chequered career with a misidentification as a Nearctic species, two junior homonyms, two replacement names and two synonymies. This is due partly to its wide distribution from Sri Lanka to the centre of the Pacific region and from the Philippines to the wet tropics of North Queensland. Fennah (1965) noted that there was some variation in the male genitalia between the two males available to him. This implies that there may be cryptic species within the complex so the chequered history of the name may yet be extended by further research. The species is distinctly coloured with white margins to the frons and the hind part of the pronotum and tip of the scutellum also white, contrasting with otherwise dark colouring.

Diagnosis

The basal segment of the antennae varies from testaceous to blackish. The middle keel of the frons in the Australasian individuals is usually blackish, though sometimes paler fuscous. The spur has about 20 spines. Male pygophore oval; anal tube cleft ventrally, with 2 diverging spines. Aedeagus a little swollen apically. Genital styles small and laterally arched, nearly meeting apically. This species is very close to "albicollis", but is a little larger, the posterior angle of the scutellum white, the frons is coloured differently and the male pygophore different. (Kirkaldy 1907, as Liburnia puella)

This is a small species, blackish or blackish fuscous in colour with lateral margins of face, posterior half of pronotum, and apex of mesonotum white. General colour black and fuscous, heavily marked with white or light ochraceous buff as follows: median carina and lateral margins of postclypeus, lateral margins of frons, carinae of vertex, posterior half of pronotum, apex of mesonotum, lateeral areas of thorax, dorsum of abdomen chiefly, except the basal areas of the segments, ventral lateral areas of abdomen, posterior tibiae and tarsi. Head short and broad; vertex about one and one-half times as long as its greatest width, slightly narrowed between eyes; lateral margins strongly elevated, broadly curved; median carina fine but distinct, postclypeal margin broader than dorsal margin; postclypeus short, triangular, about half as long as frons; lateral margins distinctly carinate, median carina broad. Antennae short, terete, first segment about one and one-half times as long as its greatest width, about half as long as the second segment. Pronotum short and broad, nearly three times as broad as its median length; posterior margin shallowly and broadly incised. Mesonotum elongate, slightly longer than pronotum, tricarinate. Tegmina brachypterous or macropterous; venation as characteristic of the family. Male genitalia with the pygofer elongate, narrow; anal segment short, terete; anal style elongate, sagittate; outer genital chamber shallow; genital styles small, obtuse at the apex with the inner angle roundly produced; connective elongate, L-shaped; aedeagus short, broad, obtuse at the apex. Length to apex of tegmina: macropterous male, 2.8 mm; brachypterous male, 1.8–2.0 mm; brachypterous female, 1.9–2.2 mm. (Metcalf 1950, as Coronacella bella)
