Figs 1 E, 2 A–E
Male. Colour. Head yellowish brown, vertex darker brown, antennal flagellomeres 2–14 brown; setae and other vestiture dark. Thorax yellowish brown, scutum and scutellum brown, the former a little paler posterolaterally and at posterior margin, anterior part of anepisternum, laterotergite and the medial part of mediotergite slightly infuscated; the thoracic setae dark. Legs yellowish brown, middle and hind femur infuscated ventrally at apex, the setae and other vestiture dark. Wing brownish; haltere yellowish brown with dark brown knob. Abdomen brown, hypopygium yellowish brown on basal half, setae dark. Head. Antennal flagellomere 4, Fig. 2 A. Other parts of head lost in the single specimen before a detailed study. Thorax similar to Fig. 8a in Hippa et al. (2004). Legs. Apical part of tibia 1, Fig. 2 B. Wing, Fig. 1 E. Wing length 2.0 mm. Hypopygium, Figs 2 C, D, E: Gonocoxae ventrally separated by a membranous area, each side appearing as a very large lobe, posteriorly extending further than the gonostylus, the posterior part two-lobed with a broad mesial lobe and narrow lateral lobe, the latter appearing as a curved prong; the ventral surface evenly rather long setose, the lateral lobe with 3–4 megasetae at apex, the dorsal surface of the broader mesial lobe with an area of numerous megasetae. The part of gonocoxa visible in dorsal view simple with the setae similar to those of the ventral side. Tergite 9 simple, the posterior margin concave, the posterolateral corner only slightly lobe-like prolonged, the setae similar to gonocoxa. Cercus simple. Hypoproct as long as cercus, each half about one third of the width of cercus, each half with 1 seta. Latero-ventrad from the hypoproct there is a setose sclerite which cannot be well observed in any of the slides and which is not drawn in Fig. 2 C. Gonostylus with a dorsal lobe, a ventral lobe and a bifid lobe between them; the dorsal lobe in dorsal view subtriangular, with a comb-like row of submembranous pale lamellae along the posterior margin; the ventral lobe expanded at apex, with a mesial comb-like row of black sclerotized lamellae and on the ventral side of the comb with a plate-like small lobe with four setae at margin; one part of the bifid lobe with an aggregation of black lamellae, the other part with a curved finger-like appendix. Parameres and aedeagus fused to form a sub-quadrangular sclerite, slightly longer than broad, aedeagal apodemes long, directed obliquely anteriod, ejaculatory apodemes similar but smaller.
Female. Unknown.
Discussion. Paramanota bifalx is similar to P. peninsulae. Both of these species differ from the other Paramanota by the ventral gonocoxal lobe which has a narrow prong-like sub-lobe in a lateral position, unlike P. orientalis, P. paxillosa and P. s c h a c h t i which has no prong-like lobe or P. furcillata, P. awanensis and P. sumatrana having it in a mesial position. P. bifalx can be distinguished from P. peninsulae by the following characters: 1) the narrow lateral sub-lobe on the ventral gonocoxal lobe has a few megasetae at the actual apex, in P. peninsulae there are numerous megasetae covering all of the mesial side of the lobe, 2) the bifid lobe on the gonostylus, between the dorsal and ventral lobes, has the part without black lamellae curved, not straight and 3) the parameres and aedeagus are completely fused, in P. peninsulae the apices of parameres are free, visible as subtriangular lobes at the apex of aedeagus.
Etymology. The name is Latin, bi-, two-, falx, sickle, referring to the pair of sickle shaped ventral lobes of the gonocoxa.
