 Type material. HOLOTYPE: J, YEMEN: Ar Rujum, 15°29′N 43°41′E, 16.x.2000 - 15.i.2001, Malaise trap, A. van Harten leg. Slide, dissected specimen, Cat. No. 34261, Inv. No. 14050 (NMPC). PARATYPES: 2 JJ (slides, NMPC), same date, Cat. No. 34262, Inv. No. 14051; 16.1.- 9.4.2001, Cat. No. 34263, Inv. No. 14052. Figures based mainly on the holotype, partially on paratypes.   
 Description. Male. Eyes not touching; frontoclypeus with central patch of insertions of hairs trilobed (Fig. 21), medial lobe thin and long, lateral ones short and rounded; areas near tentorial pits with rectangular border. Minimum distance between eyes 0.5 times as wide as diameter of facets (Fig. 26). Ratios of distance of tangential points of ends of eyes to minimum width of frons 21: 1, to facet diameter 10.5: 1. Antennae with 14 segments (Figs. 27, 28); scape cylindrical, short; pedicel almost globular; flagellomeres amphora-shaped.Apical antennomere with bulbose basis, spined, neck as well with a lateral spine, terminal part obovate with one apical seta. Sensory filaments long, thin, with four branches, paired. Length ratios of maxillary palpomeres 1: 1.1: 1.3: 1.6 (Fig. 29); palpomere 4 not annulate, connected basally with apical end of palpomere 3. Terminal lobe of labium as in Fig. 22, with four digitiform projections. Maximum length of cibarium equal to 1.3 times length of epipharynx. Thoracic sclerites as in Fig. 23, anepisternum with rounded inner apical part, pleurotergum with 2-3 hairs. Wing (Fig. 30) narrowly lancet-shaped, 2.0 mm (holotype) and 1.6-1.8 mm (paratypes) long, clear, clouded only between C and R 1; following veins or their parts strengthened: Sc, R 1, R 4 and M 1+2 basally, R 5, M 4 and Cu; basal costal nodes well visible; Sc uninterrupted; M 3, Cu and M 4 not connected basally; R 5 extending distally to reach wing margin in apex of wing; veins r-r, r-m and m-m not developed; medial wing angle 81° (BCD); wing indices: AB: AC: AD = 2.8: 3.5: 2.5; BC: CD: BD = 1: 1.6: 1.7; maximum wing length equal to 2.7 times its maximum width. Maximum length of haltere equal to 2.8 times its maximum width. Ratios of lengths of femora, tibiae and first tarsomeres: P 1 = 2.9: 2.8: 1; P 2 = 3.2: 3.7: 1.3; P 3 = 3.6: 4.4: 1.3; fore claws twice pointed and bent distad (see Fig. 31). Basal apodeme of male genitalia (Figs. 32, 33) narrowed and geniculate (dorsal view), widened from lateral aspect, rounded proximally; distal part of basal apodeme forked in two caudal arms; phallobasis with three phallomeres around gonopore; dorsal phallomeres completely fused, rounded apically from lateral view, pointed from dorsal aspect; ventral phallomere needle-shaped and bent. Paired external additional protuberances short, bilobed; inner lobuli rounded, with tufts of hairs, outer lobuli smaller and pointed. Gonocoxites (Figs. 32, 34) cylindrical with hemispherical lateral protuberances; gonostylus long, with thin pointed and bent tip, inner side covered with long hairs, outer side with one long basal seta. Epandrium (Figs. 24, 25) widely setose (one area on each side), only central rhomboidal aperture developed. Hypandrium narrow. Epiproct and hypoproct inconspicuous, hairy. Surstylus very long, bent in dorsal view, almost straight in lateral view, with one long subapical retinaculum.   
Female. Unknown.  
 Differential diagnosis. Male of Falsologima verrucosa sp. nov. is characterized by having the paired external additional protuberances near phallomeres short and bilobed, of which the inner lobule is rounded with a tuft of hairs and the outer one is smaller and pointed, large and almost equally long phallomeres, and the minimum distance between eyes equal to 0.5 times the diameter of facet. The species thus differs from F. savaiiensis (Edwards, 1928) which lacks the paired external additional protuberances of the male genitalia, has a very short rudimental ventral phallomere in contrast to fused dorsal phallomeres, and the minimum distance between eyes equal to one facet diameter.   
 Etymology. Verrucosus (Latin, adjective) = full of tubercles – in reference to the large hairy tubercles near phallomeres.   
 Bionomy. Unknown. The adults were trapped in a Malaise trap at Ar Rujum between October and April.   
 Distribution. Yemen.   
 Comments on the generic classification and extent of the genus. Falsologima Ježek & van Harten, 1996 was erected for Psychoda auct. (nec Latreille, 1796) partim with the tropicopolitan Psychoda savaiiensis Edwards, 1928 as the type species. The genus now further includes F. guamensis (Quate, 1965) from Guam, the Philippines, New Guinea, New Britain and New Ireland; F. quadrilosa (Quate & Quate, 1967) from New Guinea; F. quadropsis (Quate et Quate, 1967) from New Guinea; F. serpentina (Quate, 1965) from the Philippines and New Guinea; and F. verrucosa sp. nov. from Yemen.
