Billingham & G. Theischinger , AM (K.394961). Description ♂ ( ♀ unknown). Head : pale whitish yellow, antennal pedicel and scape pale whitish yellow, antennal flagellum with basal segments pale whitish yellow, terminal segments missing, palpus pale whitish. Figures 12–13 . hypopygium, ventral view. ( 12 ) Molophilus (Molophilus) chichester sp. nov. ; ( 13 ) Molophilus (Molophilus) trispina sp. nov. Thorax. Pronotum whitish. Prescutum, scutum, scutellum and mediotergite pale whitish yellow. Cervical sclerite and pleurites pale whitish yellow. Coxae and trochanters pale whitish yellow, other leg segments missing. Wing hyaline with veins pale whitish yellow. Halter with stem pale whitish yellow, knob white. Abdomen : pale whitish yellow. Terminalia ( Fig. 13 ). Hypopygium pale whitish yellow with lobe of tergite 9 quadrate, caudal margin straight. Gonocoxite with ventral lobe large, edges broadly rounded and apically strongly bowed mediad, ending in a dark strongly hooked beak. Inner gonostylus about ⅔ the length of the ventral lobe, mostly straight, with three spines towards the tip; one terminal, long and faintly curving medially, one long, faintly hooked on the dorsal edge, one short, appressed on the face of the style. Outer gonostylus largely parallel sided, with apex forked into two mostly even prongs. Aedeagus long and thin. Dimensions. Body length 4 mm , wing length 4.5 mm . Etymology . This species is named with reference to the threespined tip of the inner gonostylus. Discussion . Molophilus (M.) trispina is allied to numerous morphologically similar species around M. (M.) flavidellus Alexander, 1930 (see Theischinger 1992 for more details on these species). It can be distinguished from all of these species by the tip of the inner gonostylus, which bears three distinct spines.
