Formosiepyris rugulosus sp. nov. ( Figs. 1–2 )

Diagnosis. The mandible has 4 teeth, the third antennal segment is much longer than segments 2 or 4, the anterior margin of the clypeus is narrowly rounded, the lateral sides of propodeum are nearly parallel, and the surfaces between median carina and submedian carinae of propodeum lack longitudinal striae.

Female (Holotype, Figs.1–2 ). Female: HL 0.98 mm; HW 0.95 mm; WF 0.48 mm; LM 1.66 mm; LPD 0.58 mm; WPD 0.73 mm; FWL 2.03 mm; TL 5.60 mm. Body black; mandible black brown; antenna black brown, except ventral sides of flagellar segment 3–11 brown; tegulae black brown; legs black brown, except trochanters, tibiae and tarsi reddishbrown. Head approximately as long as wide, with straight posterior margin in full face view; frons and vertex densely punctate with microreticulate interspaces; punctures ca.

0.02 mm in diameter. Mandible with 4 teeth; apical tooth largest and basal most one smallest; anterior margin of clypeus narrowly rounded; length (width) of antennal segments in the following proportions: 24.0 (7.0): 10.0 (5.5): 13.5 (6.0): 11.0 (6.0): 11.0 (6.5): 10.0 (6.5): 9.0 (6.5): 8.0 (6.5): 8.0 (6.0): 7.0 (5.5): 6.0 (5.0): 6.0 (4.5): 9.0 (4.0); EL 0.58 mm; EW 0.36 mm; WF 0.83X EL. Ocelli forming right triangle; OOL 1.07X WOT. Pronotum punctate with microreticulate interspaces; pronotal punctations as that of head; dorsum flat, with median longitudinal carina at posterior 2/3; in dorsal view anterolateral corner rounded. Scutum microreticulate without punctures; scutellum microreticulated and punctured as that of pronotum. Lateral sides of propodeum nearly parallel; propodeal disc 0.79X as long as wide, with 5 discal carinae and slightly concave posterior margin; sublateral carina present; surfaces between median carina and submedian carinae of propodeum transversely striate, without longitudinal striae; declivity microreticulated, with 5 longitudinal carinae. Metasomal tergite 1 smooth and shiny, without punctures; tergite 2 with anterior 3/5 densely punctuated, and posterior 2/5 without punctures; tergite 3 with anterior half weakly microreticulated, posterior half microreticulated and punctuated, that punctuations denser than that on tergite 2; tergite 4–7 weakly microreticulated, with posterior smooth without punctures.

Var ia t io n. Body length 5.1 to 5.6 mm.

Male. Unknown.

Type material. Holotype, female, China, Fujian Province: Zhangzhou City, 24.31°N, 117.39°E, IV.1987, coll. Naiquan Lin, No. 984841. Paratypes: 1 female, China, Fujian Province: Fuzhou City, 26.05°N, 119.18°E, 10.VI.1988, coll. Jian Huang, No. 20009072; 1 female, China, Fujian Province: Xiamen City, 24.27°N, 118.06°E, 10.I.2003, coll. Hejie Chen, No. 20034437.

Distribution. China (Fujian Province).

Remarks. This species is similar to F. marishi Terayama, 2004 from Thailand, but differs from the latter mainly by having the third antennal segment much longer than segments 2 or 4, the clypeus with narrowly rounded anterior margin, OOL 1.07X WOT, the scutum microreticulated without punctures, and the lateral sides of propodeum nearly parallel.
