Redescription. Colouration ( Fig. 134 View FIGURES 134 – 137 ). Body dorsally brownish, ventral surface and appendages pale brown; anterior part of pronotal disc, head, tarsi slightly darker; hemelytra brownish, apical halves of antennomeres 4–5 sometimes darkened; apex of last rostral segment black; eyes dark with silver luster; base of clypeus laterally with narrow black lines; two median callosities on pronotum ivory to beige; membrane translucent with brownish veins and inconspicuous brownish spots among them; apical halves of claws, abdominal spiracles, and very small spots ventrally in posterolateral corners of connexival segments black.

Structure. Head ( Fig. 1 View FIGURES 1 – 8 ) medially about as long as wide across eyes; paraclypei slightly insinuated in front of eyes, parallel in median third, then arcuately rounded medially; clypeus and paraclypei not depressed to slightly depressed before apex. Dorsal surface of head covered with coarse, concolorous to brownish punctures. Antenniferes well visible from above. Antennomere 1 slightly stouter than antennomere 5 at its widest diameter. Ventral surface of head covered with concolorous to brown punctures.

Pronotum ( Figs. 9 View FIGURES 9 – 26. 9 – 20 , 134 View FIGURES 134 – 137 ) medially slightly longer than head; anterior angles slightly pointed; lateral margins before humeral angles with more or less well developed carina, only slightly concave before humeral angles; humeral angles blunt, nearly rounded, bearing only an indistinct angle produced laterally; lateral margins behind humeral angles rounded, sidelong narrowing posteriorly towards base of hemelytra, then bent inwards and nearly straight towards base of scutellum; posterior pronotal margin straight. Disc of pronotum bearing a pair of impunctate cicatrices; a pair of impunctate, not elevated, very small, round callosities ( Fig. 134 View FIGURES 134 – 137 ) developed just posteromedially behind cicatrices. Surface of pronotum covered with coarse brown punctures, distinctly denser in anterior part; spaces among punctures convex (especially in posterior part), larger ones of appearance of small callosities ( Fig. 134 View FIGURES 134 – 137 ).

Scutellum triangular, slightly longer than (rarely as long as) wide at base, slightly insinuated before apex; apex narrowly rounded. Surface covered with coarse, concolorous to brown punctures; spaces among punctures more or less convex, sometimes forming small callosities.

Hemelytra. Clavi narrow, anteriorly with 4–5 rows of punctures. Outer margin of corium widened in anterior third of its length (here the hemelytra about as wide as pronotum across humeral angles), then slightly and almost straight narrowing posteriorly. Surface covered with irregular, coarse, concolorous to dark brown punctures, never forming irregular dark lines.

Thorax ventrally (except of evaporatoria) covered with large colourless to brown punctures. Evaporatorium nearly smooth to slightly gyrificated.

Abdomen. Connexivum laterally visible from above, posterolateral angles of segments slightly protruding from the connexival outline; covered with concolorous to reddish punctures. Abdominal venter convex, covered with shallow, concolorous to reddish punctures.

Male genitalia. Pygophore in posterior view nearly oval, the posterolateral angles not protruding laterally ( Figs. 122–123 View FIGURES 122 – 131 ), lateral sides slightly rounded in ventral view (Fig. 32), posterolateral angles not prominent, wide, obtusely rounded in lateral view (Fig. 33). Dorsal sclerites nearly oval, their margins sometimes slighly undulated; base produced, but very short (Figs. 60–61), in situ slightly surpassing apex of lateral projection of paramere blade ( Figs. 122–123 View FIGURES 122 – 131 ). Parameres large, with large rectangular, apically truncated and shallowly concave blade ( Fig. 76 View FIGURES 76 – 83. 76 – 79 d), with one half-crescent dorsal and one triangular lateral projection ( Figs. 76 View FIGURES 76 – 83. 76 – 79 a–e, 80). Phallus ( Fig. 90 View FIGURES 90 – 93 ).

Female genitalia. External female genitalia ( Fig. 97 View FIGURES 97 – 100 ). Apical receptacle in examined specimen with two short, recurved processes, none of them surpassing flexible zone of intermediate part ( Fig. 105 View FIGURES 101 – 117. 101 – 104 ); distal part of spermathecal duct very short, dilatation large and long ( Fig. 101 View FIGURES 101 – 117. 101 – 104 ).

Measurements (see Table 1 View TABLE 1 ; mm). Body length 9.4–10.1 (males) / 9.8–10.8 (females). Measurements of the lectotype (ɗ): Body length 10.1; head length 2.0; head width 2.0; vertex width 1.2; length of antennomeres: 1 – 0.45, 2 – 0.75, 3 – 0.65–0.7, 4 – 0.85, 5 – 1.15–1.2; pronotum length 2.3; pronotum width 6.2; scutellum length 4.1; scutellum width 3.8.

Differential diagnosis. Among all Tripanda species, T. dispar is unmistakable by its blunt, broadly rounded humeral angles ( Figs. 9 View FIGURES 9 – 26. 9 – 20 , 134 View FIGURES 134 – 137 ). However, there also other distinct differences, e.g., the two pale median pronotal callosities are very small ( Fig. 134 View FIGURES 134 – 137 ) or completely missing; structure of pygophore (Figs. 32–33, 122–123); dorsal sclerites nearly oval with only very shortly produced base (Figs. 60–61); and structure of parameres ( Figs. 76 View FIGURES 76 – 83. 76 – 79 a–e, 80), and phallus ( Fig. 90 View FIGURES 90 – 93 ). Apical receptacle of spermatheca in examined specimen with only two very short, and recurved processes ( Fig. 105 View FIGURES 101 – 117. 101 – 104 ).

Variation. The specimens examined differ in tones of their brown colouration and punctation (hemelytra with red tinge; punctures colourless, concolorous to brown; punctures on connexivum and abdominal venter being reddish); the development of the pair of impunctate, round callosities posteromedially behind cicatrices, which may be hardly distinct or missing completely; and the development of small callosities on surface of scutellum and posterior part of pronotal disc. We also observed a difference in the lengths of antennomeres 3 in the male from Kimbenza: the ratio of lengths of antennomeres 2 and 3 being 1.5: 1.4 mm in one antenna, while 1.5: 1.6 mm in the second one.

Bionomics. The specimen from Ibadan ( Nigeria) was collected at light (this paper). The adults were collected in January, March, April, June, September, and November ( Schouteden 1909, 1911 (both as T. signitenens ), 1964b; Villiers 1967; Linnavuori 1982; this paper). At the localities Ibadan, Ile-Ife (both Nigeria), Adiapo-Doumé and Bingerville (both Ivory Coast), it was collected syntopically with T. horacekorum sp. nov., and at Foro Foro ( Ivory Coast) with both T. horacekorum sp. nov. and T. longiceps . The distribution area of T. dispar corresponds to the area of tropical rain forest and deciduous forest – woodland savanna biomes ( Fig. 147 View FIGURE 147 ).

Distribution ( Fig. 146 View FIGURE 146 ). Republic of the Congo ( Villiers (1967): Dimonika), Ivory Coast ( Schouteden (1964a, b): Bingerville; Linnavuori (1982): Foro Foro), Nigeria ( Linnavuori (1982): Ibadan, Ile-Ife), Democratic Republic of the Congo ( Schouteden (1964b): Kasaï: Dima). Considered as North Guinean faunal element by Linnavuori (1982).

Note. The Schouteden’s (1964b) information concerning type specimens should be translated as follows: ‘Mr. Decelle supplied me three specimens of this species, all three collected at Bingerville.’ In the next paragraph Schouteden further added: ‘I refer to this species also one specimen originating from former Belgian Congo: Kasaï: Dima (Koller).’ We examined three specimens from the locality Bingerville, deposited in MRAC, labeled by H. Schouteden as ‘holotype’ (a female), ‘allotype’ (a male), and ‘paratype’ (another male). However, as the holotype was not established in the original description (see ICZN 1999: 74.1.3), all these specimens are merely syntypes; we designate here a male (the Schouteden’s allotype) as lectotype. We did not examine the remaining specimen from locality Dima and cannot confirm or reject its syntype status.
