Tribe Alycini G. Canestrini & Fanzago, 1877

Type genus: Alycus C.L. Koch, 1842 .

Differential diagnosis. The tribe Alycini can be segregated from the tribes Proteromichaeliini , Bimichaeliini , Petralycini , and from the rest of the Endeostigmata, by the sensilla being filamentous or just slightly swollen (ve and sci in e.g. Fig. 1 ), chelate chelicera with two to four teeth ( Fig. 34 ), and prodorsum with a rudimentary pair of posterolateral eyes (e.g. Fig. 1 , but one undescribed exception in Australia).

Figures

FIGURES 1−5. Alycus augrabiensis sp. nov. 1—Prodorsum, integument mostly soft on crista, i.e. the area from naso to sensilla (from vi to ve), exp subequal in size with sce; 2—Dorsal habitus; 3—Integument and setal microplates; 4—Ventral habitus, 18–19 genital setae per valve, 2 eugenitals (female), 5 anal setae per valve on PA (cf. Fig. 2); 5—Genital valve of female, 19 genital setae, 1 pair of eugenital setae.

FIGURES 29−35. Amphialycus (Amphialycus) acaciae sp. nov. 29—Prodorsum, sclerotized crista, setae vi wide apart from each other; 30—Nasal area in lateral view; 31—Dorsal habitus, holotrichy; 32—Ventral habitus, 22 genital setae per valve, 8–9 anal setae per valve on PA (cf. Fig. 31); 33—Genital valve of female, 21 genital setae, 1 pair of eugenital setae; 34—Chelicera, smooth cheliceral seta more abaxially than the figure suggests; 35—Palp tarsus with 2 pairs of pseudacanthoid eupathids.
