Type materal: HOLOTYPE ♂, DRC, Kasaï-Occidental Prov., NE Ileboand KasaiRiver, XI.1997( ZSM, genitalia slide 0610). Paratypes( 14 ♂, 2 ♀total): 13 ♂, 2 ♀, data as for holotype but collected during I–III, XI–XII.1997( CGM/ BUM, genitalia slides 0611–0614). DRC: 1♂, Mai-Ndombe, Ekongocamp, 02°45’23.09”S, 20°18’55.37”E, XI.2017, leg. A. & T. Prozorov, V. Kravchenko et al. ( CGM/ BUM).
Diagnosis.Imago of T. kravchenkoigenerally smaller and darker than T. longipennis.Male forewing narrower with dark brown field from M 2to hind margin, medial lines not prominent. Female resembles T. longipennisbut without speckled coloration and with darker stroke along R-Cu cell on forewing. Male and female genitalia of T. kravchenkoiabout twice smaller but of the same shape as in T. longipennis( Figs 26–33).
Description. Male( Figs 14–15, 17–18). Head, thorax and abdomen dark reddish to greenish brown. Thorax dorsally bears triangular speckled reddish spot. Forewing: Forewing length: ca. 15 mm; wingspan: ca. 27 mm. Oval-shaped, apex rounded, outer margin slightly curved, tornal angle well pronounced, covered with longer cilia. Coloration divided into three zones: 1. light to dark brown field from costal margin to M 1; 2. light brown interspace between M 1and M 2; 3. dark brown field from M 2to hind margin. Black discal dot on R-Cu cell outer margin. Medial lines faint, crenulated. Interspace between R 4and M 2darker nearby external margin, small white spot between R 4and R 5. Hindwing: Oval-shaped tornal angle distally protruded. Brown coloration gradually darkens from costal to hind margin, submarginal field dark brown. Medial lines vague dark brown. Genitalia( Fig. 26–28): Tegumen hoodshaped with two short pointed projections. Vinculum a band ventrally widened into a bowl-like form. Valvae short finger-shaped with long base covered with chaetae, base turns ventrally into juxta projection. Juxta bilobed, each projection long finger-shaped. Aedeagus cylindrical, fused basally with juxta. Vesica bag-shaped about one-third of aedeagus length, bears one finger-shaped cornutus. 8 thsternum somewhat trapezoid with two distal lateral apexes. Female( Figs 16, 19). Bigger and paler than male. Head, thorax and abdomen yellowish or pinkish brown. Thorax dorsally bears triangular speckled reddish-yellowish spot. Forewing: Forewing length: ca. 20 mm; wingspan: ca. 40 mm. Wing similar in shape with male but larger. Background color reddish-brown. Blurred dark brown stroke almost from the wing base along M 2limited by postmedial line; faint dark brown sector between R 5and M 1limited by postmedial line. Antemedial line faint, crenulated, dark brown. Black discal dot on R-Cu cell outer margin. Postmedial line crenulated, dark brown. Submarginal line fragmented, crenulated, dark brown. Small white spot between R 4and R 5similar to male’s one. Marginal lunulae dark brown with whitish center placed between R 4, R 5, M 1, M 2, M 3, CuA 1. Hindwing: Oval-shaped, tornal angle distally protruded. Brown coloration gradually darkens from costal to hind margin, submarginal field dark brown. Medial line smooth, dark brown, accompanied by lighter band. Genitalia( Figs 31–32). Papillae anales spherical, densely covered with chaetae. Anterior and posterior apophyses of the same length. Lamella antevaginalis membranous, lamella postvaginalis sclerotized, mesally thinned. Ductus bursae very short, wrinkled. Corpus bursae membranous, wrinkled basally.
Etymology.The species is named in honor of our dear colleague and friend, lepidopterologist Prof. Dr. Vasiliy D. Kravchenko, who passed away recently. He is an example of a devoted specialist and never-give-up man who fought his illness until the very end.
Distribution.This species is found in two locations in DRC( Fig. 34), Kasaï-Occidentaland Mai-Ndombe.
Biology.Adults were collected from November to March which is a part of the rainy season in DRCand 1140 mmof rainfall measured for this period in the Ekongo camp. The mean maximum temperature was 34°C in the camp and 29°C in the forest nearby; the mean minimum was 20°C and 19°C accordingly. The only known habitat is tropical moist broadleaf forests with rare mosaic grassland patches ( Fig. 36), the elevation is around 100 mabove sea-level. One paratypemale of T. kravchenkoiwas collected on the border between forest and grassland in an area of ca. 1 hectare using an auto-trap ( Fig. 37). The larval foodplant remains unknown.
