(Figs 6–9, 11)
Type material. HOLOTYPE: ♁, ‘ MADAGASCAR: 10 km SW of Ranomafana (21°16’03’’ S 47°25’30’’ E), 980 m. a.s.l., 4.XI.2003, F. Menzel leg.ʼ (coll. SDEI).
Diagnosis. Psychomasina violina can be separated from all other Psychomasina species by the eyebridges separated by 0.25 facet diameters; wing veins without expanded areas, gonostylus with a single subapical sensillum and with indistinct terminal hook, and distal phallomeres of aedeagus without mesal teeth but with a single lateral spine (Figs 6–8).
Description. Male (n = 1). Head (Fig. 6) slightly wider than long, vertex covering about 0.3 of total head length; six pairs of postocular setae present on dorsal side, reaching third facet column from middle; eyebridge comprised of four rows of facets, separated by 0.25 facet diameters; interocular suture present, U-shaped with pronounced edges; frontal scar patch trapezoid, posteriorly with line of hairs reaching interocular suture; sides of frons area sharply delimited from rest of face by keels; clypeus with weak anterior U-shaped notch; labellae bulbous with around eight setae; only first palp segments preserved, length of first palpomere 94.5.
Antennae not completely preserved; scapus cylindrical, pedicel round; flagellomeres asymmetrically nodiform with node rounded conical; length of preserved antennal segments 105: 70: 160: 150; ascoids not preserved.
Thorax poorly preserved; dorsum, anepisternum and scutellum densely setose; laterotergite and anepimeron sparsely haired; postpronotum, katepimeron, proepimeron, katepisternum and meron bare; coxae each with dorsal stripe of setae, mid coxae with strong mesal protuberance covered in pores (as in Fig. 3); legs otherwise not present.
Wing (Fig. 7) 2.38 mm long, 0.92 mm wide; costa with single break, thickened basally over S c; S c elongate, weakly curved, almost reaching C; R 5 terminating below wing apex; radial fork distal to medial fork, apex of CuA 2 distal to radial fork; jugum broadly triangular.
Genitalia (Fig. 8) with hypandrium narrow, connected at sides to narrow gonocoxal condyle bridge, together appearing like a membranous structure with anterior and posterior margins sclerotized; gonocoxite about half length of gonostylus; dorsally without sclerotized projections but with mesal elongate seta; gonostylus curved laterally; bulbous at base, with long tube-shaped main shaft with pointed apex; setiform sensillum present subapically; aedeagus with basiphallus narrow in dorsal and ventral views, distally Y-shaped; distiphallus consisting of two symmetrical S-shaped phallomeres jointed to basiphallus; aedeagus with basolateral joint with ventral epandrial plate and mediodistal lateral spine; parameral sclerite elongate V-shaped, more than twice as long as distiphallus; epandrium (Fig. 9) about as wide as long; with single median oval aperture; ventral epandrial plate membranous, U-shaped; surstyli of even width throughout length, slightly curved in the dorsoventral plane, with 15 tenacula in single group inserted distally; tenacula nearly as long as surstylus, with apices appearing frayed; proctiger consisting of membranous oval epiproct (not illustrated) and trilobate micropilose hypoproct with median lobe of rounded V-shape and lateral lobes angulate; area of surstylus flanking proctiger with mesal darkened notch.
Biology. The type specimen was collected near a small brook in a primary alpine rainforest in Southern Madagascar. The holotype of Psychomasina armata was collected in similar habitats, but four degrees further north.
Etymology. Named after Latin violina, violin, because the distal phallomeres resemble the F-holes of a violin. The name is to be treated as a noun in apposition.
Remarks. With the description of Psychomasina violina sp. nov., 27 species of Psychodidae are known from Madagascar; including 13 species of Psychodinae, 13 of Phlebotominae and one species of Trichomyiinae (QUATE 1957, JEŽEK 2004, DEPAQUIT et al. 2008, RANDRIANAMBININTSOA & DEPAQUIT 2013, RANDRIANAMBINTSOA et al. 2014).
