Nototelmatoscopus (Jozifekia) sasakawai sp. nov.

( Figs. 19–36 , 54 )

Type locality. Malaysia, Sabah, Kepong.

Type material. HOLOTYPE: J ( NMPC: Cat.No. 34498, Inv.No. 17660), MALAYSIA: SABAH: Kepong , 5.–6.viii.1986, M.Sasakawa leg. Slide, Canada Balsam, dissected specimen . PARATYPE: J ( NMPC: Cat. No. 34499, Inv. No. 17661), the same locality and data, dissected. The figures are based mainly on the holotype.

Description. Male. Head distinctly broader than high ( Fig. 19 ), eyes separated, vertex largely triangular, on midline approximately three times as wide as frons. Eye bridge of four facet rows, minimum distance between apices of eyes equal to a little more than two diameters of facet ( Fig. 20 ). Frontoclypeus with almost circular patch of insertions of hairs, upper area of patch pointed but not touching convex frontal suture. Antenna ( Figs. 21 , 27 ) with 16 antennomeres. Antennomere 16 twice strangulated and tapering, composed of two basal parts and one digitiform terminal part. Scape long, widened distally, 1.8 times as long as pedicel, the latter almost globular. Flagellomeres excentrically bulbous (not conspicuously) with rather long necks. Ascoids ( Fig. 28 ) of flagellomeres needle shaped, multiple, arranged in a ring, long, bent. Mouthparts small, maxilla and epipharynx as in Figs. 31 and 32 . Length ratios of maxillary palpomeres equal to 1: 1.5: 1.7: 1.8. Palpomere 4 annulate ( Fig. 22 ), connected basally with the apical area of palpomere 3. Labium and labial lobes with many minute folds ( Figs. 29, 30 ). Cibarium 2.1 times as long as epipharynx.

Thoracic sclerites as in Fig. 33 . Allurement organ conspicuously reduced; only widely spaced insertions of hairs present near spiracle. Haltere spatula-shaped, with many scales ( Fig. 34 ). Wings 1.7 mm long (holotype and paratype), widely lancet shaped, apex rounded ( Fig. 54 ), wing membrane bare, radial and medial forks complete; the following veins or their parts strengthened: Sc conspicuously at base (then gradually tapering to a forked broader small patch), almost whole R 1 distally, R 2+3, R 2, R 3, R 5, M 1, M 2, M 4 and Cu (last two conspicuously strengthened at base). R, M and Cu narrow before the junction with wing margin. Basal costal nodes distinct. Sc uninterrupted. Bases of M 3 and M 4 distant from basis of Cu. R 5 extending distally to reach wing margin a little below rounded apex of wing. Veins r-r, r-m and m-m not developed. Medial wing angle 163° (BCD). Wing twice as long as wide. Wing indices AB: AC: AD = 5.8: 5.5: 4.8; BC: CD: BD = 1: 2.5: 3.5. Length ratios of femur, tibia and first tarsomere equal to: P 1 = 2.3: 2: 1; P 2 = 2.6: 3.3: 1.8; P 3 = 2.6: 3.7: 1.6. Fore claws as in Fig. 35 .

Basal apodeme of male genitalia long and thin, almost straight in dorsal view, inconspicuously S-shaped in lateral view. Aedeagal complex ( Figs. 23 , 36 ) conspicuously long and simple, narrowed caudally in lateral view. Gonocoxites long, expanded at base in dorsal view, provided with numerous very long hairs; gonostyli slender, little shorter than gonocoxites in lateral view, gradually tapering to apex and a little bent before end ( Figs. 23, 24 ). Epandrium rectangular, bare, without apertures ( Figs. 25, 26 ). Remainders of tergite 10 and sternite 10 inside epandrium not visible. Caudal coupling of epandrium and hypandrium developed but hypandrium formed as inconspicuous ligament. Hypoproct large, long, almost triangular, with rounded apex, haired ( Figs. 25, 26 ). Epiproct very small, hemicircular, haired. Surstyli cylindrical, almost straight in dorsal view, a little bent in lateral view, expanded basally. Number of retinaculi 11–13.

Female unknown.

Differential diagnosis. Because many species of Paramormiina were inadequately described and I have not seen all type specimens (or the species are known only from females), a direct comparison of the males of Nototelmatoscopus (Jozifekia) sasakawai sp. nov. with them is not possible. The most important morphological characters that characterize the new species are as follows: R 4 ending conspicuously above the apex of wing ( Fig. 54 ); R 5 reaching the wing margin slightly below the apex; haltere spatula-shaped ( Fig. 34 ), with many scales; aedeagal complex with a characteristic shape ( Fig. 36 ); epandrium bare ( Fig. 26 ), with caudal coupling, hypandrium formed only by an inconspicuous ligament without sclerotization.

Etymology. The species is dedicated to Prof. Mitsuhiro Sasakawa (Osaka Prefecture, Japan), who collected the type material of this species.

Bionomy. Unknown.

Distribution. Malaysia: Kalimantan: Sabah state.

Perakomyia gen. nov. Type species. Perakomyia sifneri sp. nov., present designation.

Diagnosis. Perakomyia gen. nov. is characterized by the following characters: radial fork of wing behind medial fork and medial fork a little behind the end of Cu ( Fig. 55 ); end of R 4 in apex of wing; R 5 extending distally and reaching wing margin below apex; costal vein depressed near the end of Sc; aedeagal complex ( Figs. 51, 52 ) distally with paired lateral minute sclerotized protuberances with blunt tips; hypandrium enlarged in middle ( Fig. 51 ); surstyli with conspicuously prolonged area of insertions of retinaculi ( Figs. 44, 45 ).

Differential diagnosis. Perakomyia gen. nov. is similar to Iranotelmatoscopus Ježek, 1987 . However, in Iranotelmatoscopus the radial fork of the wing is conspicuously behind the medial fork, the latter is at a large distance behind the end of Cu, the end of R 5 is in the apex of wing, R 4 ends before the apex, the costal vein is not depressed near the end of Sc, the aedeagal complex has paired long and pointed protuberances distally, the hypandrium is narrow in the middle and the surstyli have a circular area of insertions of the retinaculi.

Etymology. The name is a combination of Perak (silver in Malayan language), the second largest state in Peninsular Malaysia, and myia, the Greek word for a fly. The gender is feminine.

Included species. Perakomyia sifneri sp. nov. (Peninsular Malaysia) and P. kalabakensis (Quate, 1962) comb. nov. (northern Kalimantan).
