A female specimen of Diadocidia is also preserved in the HNHM: TAIWAN, Taichung Hsien, Piluchi, TFRI Site, 2200 m – Dec 26–28, 2001, leg. L. RONKAY & A. KUN. That was thought to be the female of the above species by the senior author, but now we think, that may belong to another, undescribed species (the fourth Diadocidiidae species of Taiwan).
Female (body length 2.86 mm, wing length 4.58 mm) similar to the male of D. sevciki with the same dark scutum, also its palpi black, cerci black (ochre with brown apex in D. setistylus ). Contrary to the holotype of D. sevciki , mesoscutal and abdominal setae very long and light (not black), costal vein runs to more than ½ of section between R 5 and M, legs yellow, but tarsi black, vein R 1 ends just at level of M fork base. M ratios 0.49, 0.625; this again contradicts conspecificity with D. sevciki . Fore leg with tarsomeres 2 to 4 slighly swollen, tarsomere 1 being the thickest, tarsomere 2 0.065 mm thick, tarsomere 3 0.055 mm thick. Length ratio of fore tarsomeres 75:23:20:16:12.5. Cx 3 posteroventrally with 9 long setae.

Etymology. The specific name refers to the type locality.
Measurements (in mm): body length 2.45, wing length 2.14, wing breadth 0.91.
Head and thorax orange brown, legs and abdomen brownish yellow.
tail of gonostylus. Scales: 0.1 mm for Figs 11, 13 View Figs 11–14 , 0.01 mm for Figs 12, 14 View Figs 11–14
Head. Three ocelli. Lateral ocelli about as large as median, and separated from the eye margin by a distance of about 1.2 times their diameter. Frons and clypeus setose. Scape and pedicel yellowish, about as long as wide, with dark setae. Mouthparts and palpi brownish yellow. Palpus with 4 palpomeres, covered with dark setae. Palpomere 4 (apical) long and narrow. Relative lengths of palpomeres 1 to 4 are 1:2:3:6.
Thorax. Mesoscutum brownish, with indistinct longitudinal stripes bearing dark setae. Lateral margins of mesoscutum with long setae. Scutellum with four apical bristles. Mediotergite, laterotergite, anepisternum and preepisternum 2 bare. Antepronotum with several setae. Halteres yellowish brown.
Wings. Hyaline, both membrane and veins covered with macrotrichia. Ratio of length to width 2.3. Costa well produced beyond R 5, reaching to about a third of the distance to M1 Sc ending in C well before base of Cu-fork, but its apical part weak. Sc 2 absent. R 1 ending in C slightly before base of M-fork. The ratio of the length of R 1 to the total wing length is 0.55. Veins R-M and M-Cu in one line. M ratios: 0.55 and 0.69, Cu ratios: 0.47 and 0.81. Both Cu 2 and A 1 distinct and setose, the latter reaching wing margin. Calypter with several long setae along its margin.
Legs. Coxae yellowish brown, with a longitudinal row of black setae, c1 and c2 anterolaterally and c3 posterolaterally, the longest setae almost as long as the width of coxa. Apical part of c2 and c3 with black spots.
Abdomen. Brown, all tergites and sternites covered with long dark setae.
Terminalia ( Figs 11–12 View Figs 11–14 ). Brownish yellow. Length of terminalia 0.28 mm. Width 0.32 mm. Gonocoxite swollen. Gonostylus narrow, curved, apically darkened, basally setose, with a relatively strong thorn in the middle ( Fig. 12 View Figs 11–14 ). Gonocoxites almost separated, joined by narrow ventral bridge. Aedeagal complex consists of two parts, Y-shaped aedeagal apodemeand T-shaped fused parameres, the latter rather narrow. Tergite 9 semicircular, cerci remarkable, each bearing a patch of long setae.
Female unknown.
Diagnostic characters. A small species of Diadocidia s. str., similar to D. cizeki ŠEVČÍK, 2003 and D. halopensis ŠEVČÍK, 2003 . Terminalia are very characteristic, especially those long setae on cerci.

Holotype male ( BMNH): Sulawesi, Suunny Mogogonipa, 20.10.1985, leg. J. S. Noyes (Malaise trap). (Placed in a pinned microvial filled with glycerol.)
Etymology. The specific name refers to the type locality.
Measurements (in mm): body length 2.62, wing length 2.45, wing breadth 1.05.
Head and thorax orange brown, legs and abdomen brownish yellow.
Head. Three ocelli. Lateral ocelli slightly larger than median, and separated from the eye margin for a distance of about their diameter. Frons and clypeus setose. Scape and pedicel yellowish, about as long as wide, with dark setae. Length of antenna 1.3 mm, length of flagellum 1.1 mm. Scape and pedicel yellowish, about as long as wide, with dark setae. Flagellum dark brown, cylindrical, densely covered with fine setulae, tapering towards apex, with 14 flagellomeres. Base of first flagellomere yellowish. Ratio of length to width for flagellomeres 1 to 13 is 1.7 and for the apical flagellomere 2.4. Mouthparts and palpi brownish yellow. Palpus with 4 palpomeres, covered with dark setae. Palpomere 4 (apical) long and narrow. Relative lengths of palpomeres 1 to 4 are 1:2:4:8.
Thorax. Mesoscutum brown, with indistinct longitudinal stripes bearing dark setae. Lateral margins of mesoscutum with long setae. Scutellum brown, with several long dark apical bristles, about twice as long as scutellum. Mediotergite, laterotergite, anepisternum and preepisternum 2 bare, brown. Antepronotum with several long setae. Halteres brown.
Wings. Hyaline, both membrane and veins covered with macrotrichia. Ratio of length to width is 2.3. Costa well produced beyond R 5, reaching to about a third of the distance to M 1 Sc ending in C well before base of Cu-fork. Sc 2 absent. R 1 ending in C slightly beyond the base of M-fork. The ratio of the length of R 1 to the total wing length is 0.59. Veins R-M and M-Cu in one line. M ratios: 0.63 and 0.77, Cu ratios: 0.47 and 0.88. Both Cu 2 and A 1 distinct and setose, the latter reaching wing margin. Calypter with several long setae along its margin.
Legs. Yellowish, covered with dark trichia and setae. All coxae with a longitudinal row of long black setae, c1 and c2 anterolaterally and c3 posterolaterally, the longest setae almost as long as the width of coxa. All trochanters and tips of coxae with a black spot ventrally. Femora laterally compressed and thickened medially, clothed with numerous trichia and with a row of longer setae along ventral edge. Mid tibia with 2 weak ventral setae. Hind tibia with 6–8 dorsal setae.
Abdomen. Brown, all tergites and sternites covered with long dark setae.
Terminalia ( Figs 13–14 View Figs 11–14 ). Brownish yellow. Length of terminalia 0.25 mm. Gonocoxites relatively long and narrow. Gonostylus about a half the length of gonocoxite, tapering, directed anterodorsally, apically slightly bifid and bearing a strong pointed thorn and a small subapical seta. Gonocoxites almost separated, joined by narrow ventral bridge. Aedeagal complex consists of two parts, Y-shaped aedeagal apodeme and T-shaped fused parameres. Tergite 9 small, tranverse, subtriangular.
Female unknown.
Diagnostic characters. This species is very similar to D. cizeki . It has, however, shorter gonostyli with pointed thorn and a more triangular tergite 9 than the latter species.
