Redescription. Colouration (Fig. 135). Entire body, including appendages, pale brown, ventral surface and appendages slightly paler than dorsal surface; anterior part of pronotal disc, head (usually), and antennomeres 4–5 slightly darker; eyes dark brown to black; base of clypeus laterally with very narrow black lines; two median callosities on pronotum beige, only slightly paler than surrounding surface; membrane translucent with brown veins; spiracles on abdominal venter, apices of claws, and apex of rostrum black.
Structure. Head (Fig. 7) medially slightly longer than (rarely as long as) wide across eyes; head in front of eyes parabolic, paraclypei straight to very slightly sinuated in front of eyes, slightly narrowing apicad, then arcuately rounded medially; clypeus and paraclypei not depressed before apex. Dorsal surface of head covered with coarse, concolorous punctures. Antenniferes hardly visible from above. Antennomere 1 as stout as antennomere 5 at its widest diameter. Ventral surface of head covered with concolorous (on bucculae brown) punctures.
Pronotum (Figs. 17, 135) medially only slightly longer than head; anterior angles nearly rectangular, not pointed; lateral margins rounded, broadly concave before humeral angles; humeral angles spinously produced laterally and slightly anteriorly; lateral margins behind humeral angles sidelong narrowing posteriorly towards base of hemelytron, then bent inwards and slightly concave towards base of scutellum; posterior pronotal margin straight. Disc of pronotum bearing a pair of impunctate cicatrices and medially behind them a pair of impunctate, elongated, horizontally oriented, not elevated callosities. Surface of pronotum covered with coarse brown punctures, spaces among punctures convex, larger ones of appearance of small callosities (especially in posterior part).
Scutellum triangular, slightly longer than (rarely as long as) wide at base, slightly insinuated before apex; apex narrowly rounded. Surface covered with rather deep colourless to brownish punctures; spaces among punctures more or less convex, sometimes forming small, not elevated callosities.
Hemelytra. Clavi narrow, anteriorly with 3–4 rows of punctures. Surface covered with irregular, coarse, concolorous to brown punctures, brown punctures sometimes form irregular dark lines.
Thorax ventrally (except of evaporatoria) covered with large colourless punctures. Peritreme and evaporatorium as in Fig. 28; evaporatorium smooth, without apparent gyrification.
Abdomen. Distinctly narrower than pronotum. Connexivum visible from above, posterolateral angles of segments slightly protruding from connexival outline; covered with concolorous to pale brown punctures. Abdominal venter convex, covered with shallow, concolorous to pale brown punctures.
Male genitalia. Lateral sides of the pygophore nearly parallel (Fig. 42); posterolateral angles narrowly produced in lateral view, apically slightly curved ventrally (Fig. 43); ventral wall of pygophore less gibbous in lateral view (Fig. 43); ventral rim of pygophore medially with obtuse, broadly trapezoidal projection (Figs. 42, 44). Base of dorsal sclerites not projected, wide; sclerites small, nearly oval with parabolically produced apex (Figs. 70–71). Parameres with large flat blade with one low dorsal ridge-like and one lateral finger-like projection (Figs. 78–79, 82–83); apex of paramere blade rectangularly truncated (Figs. 78, 82, 138–139). Phallus small (Fig. 92).
Female genitalia. Spermatheca nearly identical to those of T. decorata, apical receptacle smaller (Fig. 117).
Measurements (see Table 1; mm). Body length 7.9–8.7 (males) / 8.7–9.0 (females).
Variation. Females are slightly longer than males. The specimens examined differ slightly in tones of their brown colouration and punctation (punctures colourless, concolorous to brown; punctures on connexivum and abdominal venter being reddish), the development of small callosities on surface of scutellum and posterior part of pronotal disc, and presence of irregular rows of brown punctures on hemelytra. We also observed differences of the lengths of antennomeres 2 and 3; antennomere 2 is usally slightly longer than antennomere 2, but in one specimen their lengths are equal (1.4: 1.4 mm), and in one specimen the antennomere 2 is shorter (1.45: 1.6 mm).
Differential diagnosis. Tripanda collaris is most similar to T. decorata, both differing substantially from all Tripanda s. str. species by the posterolateral angles of pygophore projected and apically curved ventrally, structure of the paramere, and especially by the differences in the structure of spermatheca. Tripanda collaris differs from the continental T. decorata by its smaller size and the following characters: Body dorsally pale brown, without yellowish tinge. Median pronotal callosities beige, only slightly paler than surrounding pronotum (Fig. 135), more narrow and elongated (Fig. 24). Humeral angles of pronoum narrow, distinctly pointed (Fig. 17). Ventral rim of the pygophore medially with obtuse, broadly trapezoidal projection (Figs. 42, 44); projected posterolateral angles of pygophore shorter; ventral wall of the pygophore less gibbous in lateral view (Fig. 43). Apex of the paramere blade rectangularly truncated (Figs. 78, 82, 138–139). Phallus (Fig. 92).
Bionomics. According to P. Švácha (pers. comm.), the specimens from Ankingameloka village were collected at light in area with sparse forest and treeless patches, about 100 m a.s.l. At Morondava it was caught in a forest. Adults were collected in January and November (Cachan 1952). The distribution area of T. collaris corresponds to the areas of tropical rain forest and deciduous forest – woodland savanna biomes (Fig. 147).
Distribution (Fig. 146). Madagascar (Cachan (1952): Fort-Dauphin, Maevatanana, Maromandia; this paper).
