Type species: Thinobatis ferruginea Eschscholtz, 1831 , by monotypy.

Description. In addition to the characters stated above: Mandibles thick, base 2X wider than apex, both mandibles with dorsal cusp on basal half, shorter on right than on left mandible ( Fig. 5 View Figs ), lacking ventral fossa; labrum exposed, entirely sclerotized; clypeus short, not covering labrum, anterior margin straight or concave, nearly at same level with antennal insertions, lacking row of teeth ( Fig. 5 View Figs ); prementum partially sclerotized, base concealed beneath mentum; anterior margin of mentum narrowly notched ( Fig. 7 View Figs ); eyes small, not protruding, upper margin lacking carina; length of epicanthus 1.5X length of eye ( Fig. 5 View Figs ); antennae reaching posterior margin of pronotum, antennomere 1 as long as 3, emerging from distal half of antennal insertion ( Fig. 7 View Figs ), antennomere 3 longer than 2 ( Fig. 5 View Figs ), antennomeres 9 and 10 triangular, strongly expanded outwards, wider than long, antennomere 11 equal to or longer than 10 ( Fig. 9 View Figs ). Pronotum with anterior angles acute, directed forwards, or rounded sloping towards venter ( Fig. 1 View Figs ). Metasternum short, as long as mesosternum. Metacoxae separated by less than half metacoxal width; metacoxal width 3X metacoxal length; distance between meso– and metacoxae equal to metacoxal length ( Fig. 11 View Figs ). First tarsomere of hind legs longer than 2+3 combined.

Species Included. T h i n ob a t i s f e r r u g i ne a Eschscholtz, Thinobatis rufipes rufipes Solier , Thinobatis rufipes penai Freude , Thinobatis rotundicollis Waterhouse , Thinobatis intermedia Philippi and Philippi , Thinobatis kuscheli Kulzer , Thinobatis brevicollis Kulzer , Thinobatis calderana Kulzer , Thinobatis melcheri Freude , Thinobatis simplex Peña , Thinobatis punctata Peña , Thinobatis confusa Peña , and Thinobatis arenaria Peña ( Peña 1974b) .

Material Examined. Thinobatis intermedia , T. melcheri , T. rufipes rufipes , and T. rufipes penai (IADIZA) . We also examined T. rotundicollis , but it should be classified in a distinct genus because of the shape and proportional length and width of the pronotum, rounded pronotal posterior angles, lack of a dorsal cusp on both mandibles, and clypeus and frons with protuberances.
