Terpnistriella bredoi n. sp.

Figs 10A–10H

Material examined and depository. Democratic Republic of Congo, Elisabethville (now Lubumbashi ) 27.IV.1939, H.J. Brédo (light) (♂ holotype, 1♂ paratype) ( RBINS).

Measurements. Male. Body length: 21.0–21.5; length of pronotum: 5.9–6.0; height of pronotum 5.0–5.1; length of tegmina: 37.9–38.5; width of tegmina: 8.2–8.5; length of hind femora: 26.0–26.7; length of hind tibiae: 28.0–29.3.

Diagnosis. Very characteristic for its hind femora with 10–11 ventral spines in both margins, of which the last 3–4 are large, broad-based and expand into flat, pointed lobes, pronotum without raised margins and hind wings with a wide reddish patch.

Description of the male. Colour. Body yellowish, posterior margin of pronotum lobes black, lateral mesosternum black, tarsi blackish, spine of femora black, those broad-based only black on superior margin ( Fig. 10A ). 4–5 brown spots on posterior part of tegmina, second pair of wings with a wide reddish area ( Fig. 10B ). Head without fronto-genal carinae. Fastigium of vertex compressed, narrower than first antennal segment, sloping steeply to frons, sulcate above. Eyes round, prominent, wider than subocular groove. Pronotum straight along anterior margin, without median carina; lateral carinae just visible in the posterior part, mainly after pronotum excision; surface smooth and covered by small pilosity. Fore coxae armed with a fine spine. Fore and mid femora unarmed. Hind femora with 10–11 ventral spines in both margins, of which the last 3–4 are large, broad-based and expanded into flat, pointed lobes ( Fig. 10D ). Fore tibiae with closed tympanum on inner and open on outer side, with 4 spines on ventral margins, and 1–2 on outer dorsal margin + 1 spur. Mid tibiae with 8 spines on ventral margins and 3 + 1 spur on inner dorsal margin. Hind tibiae with 18–20 ventral spines on both margins and ca. 30 broad-based small spines on dorsal margins + 3 apical spurs on each side ( Fig. 10D ). Both pairs of wings fully developed. Stridulatory area of left tegmen a little elevated above wing plane ( Fig. 10B ); stridulatory file curved, 1.8 mm long and consisting of ca. 30 teeth evenly spaced ( Fig. 10C ). 10th abdominal tergite straight with two lateral small down-curved tips ( Figs 10E, 10F ). Cerci stout, in-curved and pointed ( Figs 10E, 10F ). Subgenital plate upcurved, narrow, long, tri-carinate and apically concave, styli absent ( Figs 10G, 10H ).

Etymology. This species is dedicated to the late H.J. Brédo, collector on behalf of the Royal Belgian Museum in the Democratic Republic of Congo and other tropical African countries; he collected series of very interesting Orthoptera and other orders of Insecta, among which specimens are two new genera here described.
