Recognition
Species of Haywardina may be distinguished from other Tephritidae by the following
combination of characters: .
Description
Head: Yellow except brown between ocelli. 3 frontal setae. 1-2 reclinate orbital
setae, if 2, separated by less than distance from anterior seta to eye margin. Ocellar
seta strong. Face with distinct carina. Antenna short to medium length, never extended to
ventral margin of face; first flagellomere tapered, with small dorsoapical point; in
lateral view 1.7-3.2 times as long as wide.
Thorax: Usually mostly yellow with brown marks on scutum and often on scutellum, anepisternum, katepisternum, katatergite, or mediotergite, or mostly brown with orange anepisternum (H. obscura). Scutal brown spots on mesal side of lateral white stripe not connected posteriorly (not forming U-shaped mark). Also with following white areas: medial scutal stripe or spot; narrow lateral postsutural scutal stripe, usually not extended along transverse suture (except in H. cuculiformis); postpronotal lobe (except in H. obscura); apex of scutellum; and dorsal anepisternal stripe. Notopleuron and katepisternum without white markings. Thorax usually entirely microtrichose (bare in H. cuculiformis). Dorsocentral seta slightly to distinctly posterior to postsutural supra-alar seta but closer to it than to postalar seta.
Wing: Crossvein R-M near middle of cell dm, less than 0.60 distance from BM-Cu to DM-Cu, except in cuculi. Subbasal, discal, and apical crossbands present. Discal band with anterior end basally curved, usually connected to subbasal band in cells c, r1, and/or r2+3; not extended over DM-Cu, except in cuculi. Subapical band present (except in H. cuculi), connected to or separate from discal band at posterior wing margin. Apical band connected to subapical band at anterior wing margin or isolated. Posterior apical band absent. Accessory costal band present or absent.
Abdomen: Tergites mostly yellow with brown spots, usually at least tergite 5 with basal submedial pair.
Male terminalia: Lateral surstylus elongate, with distinct mesal lobe near prensisetae. Medial surstylus elongate.
Female terminalia: Aculeus tip slender, acute, entire or with small subapical notches. 2 spermathecae, small, ovoid or spherical, with short base.
