Chonocephalus collini sp. nov.

( Figs 13­16 )

Chonocephalus similis Collin, 1912: 105 , part (male only) nec Brues, 1905. Misidentification.

I have remounted four of Collin’s males attributed to C. similis and found three to be this undescribed species and one to be C. depressus (see below). His females attributed to C. similis are partly C. dominicanus (see below) and partly C. heymonsi (see below) and partly a hitherto undescribed species, which will be dealt with in a future paper on the Afrotropical species

Male

Frons brown with a darker ocellar triangle. Third antennal segment brown and 1.2­ 1.3x as broad as palp, which is paler, yellowish, brown with numerous hairs and a differentiated fine apical bristle. Hypopygium mainly pale brown. The left side of epandrium with a darker process bearing a differentiated bristle and the adjacent surstylus is also dark ( Fig. 13 ). The left gonopod straw yellow lightly tinged brown and paler than the longer, sinuous, hypandrial process ( Fig. 16 ). Right gonopod ( Figs 14 and 15 ) a little darker than left but paler than tip of right hypandrial process ( Fig. 15 ). The lowest 2­3 hairs of right side of epandrium situated on a small projection. Legs brown, but mid and front tibiae paler. Wing 1.0­1.1 mm long and brownish grey tinged.

PARATYPES 16 males, as holotype (8­130­132); 1 male, Lantana/Lantana North, marsh edge, Malaise trap in open, 30 July­1 August 2000, J.
