Description. Male. Eyes separated, frontoclypeus with rectangular patch of insertions of hairs connected with dorso-ventral stripe irregularly arranged hair pits between upper apices of eyes ( Fig. 1 ). Minimum distance between eyes 0.5 times as wide as diameter of facet ( Fig. 10 ). Ratios of distance of both tangential points of eyes (dorsal and ventral) to minimum width of frons 9: 1, to facet diameter 18: 1. Antenna with 14 segments ( Figs. 2 , 11); scape almost ovoid, slightly longer than pedicel, the latter hardly globular; flagellomeres 1-9 pitchershaped, nodes bulbose, internodes (necks) shorter than nodes; antennomeres 12-14 progressively decreasing in size, almost globular, segment 12 quite separated, antennomeres 13 and 14 fused; sensory filament composed of two anterior and one posterior branch. Length ratios of maxillary palpomeres ( Fig. 12 ) 1: 1: 1: 1.5, palpomere 4 not annulate, tapering gently to apex. Terminal lobe of labium ( Fig. 3 ) with four digitiform protuberances and two long setae. Ratio of maximum length of cibarium to length of epipharynx 1.3: 1. Thoracic sclerites as in Fig. 13 . Wing ( Fig. 14 ) of characteristic psychodini-shape, clear, 1.3 mm (holotype) and 1.3- 1.6 mm (paratypes) long, wing membrane bare, radial and medial forks complete; following veins or their parts strengthened: Sc (considerably), R 1, R 2, base of R 4, R 5, basal part of M 1+2, M 4 and begining of Cu (conspicuously); basal costal nodes distinct; Sc uninterrupted, bent; M 3, Cu and M 4 not connected basally; R 5 reaching to wing margin with round apex; medial wing angle 96° (BCD); wing indices: AB: AC: AD = 3: 3.5: 2.6 and BC: CD: BD = 1: 1.9: 2.2; maximum wing length equal to 2.3 times its maximum width. Maximum length of haltere equal to 3.3 times its maximum width. Ratios of lengths of femora, tibiae and first tarsomeres: P 1 = 2.6: 2.5: 1; P 2 = 2.9: 3.2: 1.1; P 3 = 3.3: 3.9: 1.2; fore claws generally bent, form depending on angle of view ( Figs. 4, 15 ). Basal apodeme of male genitalia narrow, slightly bent proximally (in dorsal as well as in lateral aspect, Figs. 5, 16 ). Phallobasis bagshaped, with three phallomeres around gonopore, dorsal phallomeres broad, completely fused, distorted in lateral view, ventral phallomere needle-shaped, bent, shorter than dorsal one. Gonocoxites short, thick, protruding laterally in dorsal view; gonostylus thin, 1.5 times as long as gonocoxite ( Figs. 5, 6 ), pointed. Epandrium ( Figs. 7, 17 ) with one large field of insertions of hairs on each side. Basal aperture as well as sclerotized remainders of tergite and sternite 10 inside of epandrium missing. Hypandrium narrow ( Fig. 5 ). Epiproct hardly visible, hypoproct small, with tongue-shaped lobulus in middle, hairy. Surstylus long, distinctly longer than epandrium, bulbose basally ( Figs. 7, 17 ), S-shaped in dorsal view, C-shaped in lateral one, subapically with one rather large retinaculum.

Female. Similar to male. Wing 1.2-1.4 mm long. Genitalia as figured ( Figs. 8, 9, 18, 19 , 20), subgenital plate ( Fig. 18 ) bilobed, with shallow apical concavity, hairy; sensory digital organ developed; plate with a pointed sclerotized rib in medial line basally; complicated sclerotized forms of genital chamber without mesh-like structures ( Figs. 8, 19 , 20). Cercus ( Fig. 9 ) hardly twice as long as subgenital plate, bent.

Differential diagnosis. Copropsychoda bulbosa sp. nov. is characterized by having the radial and medial forks of wings complete ( Fig. 14 ), the ventral male phallomere rectangularly bent at the base and without a conspicuous ring, the gonocoxites bulbous basally ( Fig. 5 ), and the subgenital plate of female with convergent sides ( Fig. 18 ). The most closely related spe-

Copropsychoda bulbosa sp. nov., J (10-17) and ♀ (18-20). 10 – facets; 11 – apical antennomeres; 12 – maxilla and maxillary palpus; 13 – lateral view of thoracic sclerites; 14 – wing; 15 – lateral view of fore claw; 16 – lateral view of aedeagal complex; 17 – dorsal view of epandrium and surstyli; 18 – subgenital plate; 19 – dorsal view of genital chamber; 20 – same, lateral view. Scales = 0.1 mm ( Figs. 10 -13, 16-20); 1 mm ( Fig. 14 ); 0.05 mm ( Fig. 15 ).

cies Palaearctic C. brevicornis (Tonnoir, 1940) has incomplete radial and medial forks, ventral phallomere with a fully developed basal ring which is only inconspicuously bent at the base, only slightly strengthened gonocoxites, and an almost parallel-sided female subgenital plate.

Etymology: Bulbosus (Latin, adjective) = bulbous – gonocoxites with conspicuous lateral protuberances.

Bionomy. Unknown. The adults were collected from October to June in a Malaise trap at Ar Rujum.

Distribution. Yemen.

Comments on the generic classification and extent of the genus. VAILLANT (1971) described the genus Copropsychoda , separating it from Psychoda Latreille, 1796 . He did not establish the type species but included only C. brevicornis (Tonnoir, 1940) in the new genus. It should therefore be recognized as the type species by monotypy. Four species of Copropsychoda are now known: C. brevicornis from Europe and West Siberia ( JEŽEK 1992), C. miyatakei ( Tokunaga, 1958) from Japan, C. dewulfi (Satchell, 1955) from the Belgian Congo (currently Democratic Republic of the Congo) and C. bulbosa sp. nov. from Yemen.
