120 BULLETIN AMERICAN MUSEUM OF NATURAL HISTORY NO. 304 apically. Apical process of first metatarsomeres very reduced. 1mt /2–5mt 5 0.5. MALE: Unknown. Paramblynotus distictus is very similar to P. fraxini and P. kosugii. It can be easily separated from all other Paramblynotus species by having a longitudinally carinate occiput and pronotum raised anteriorly into a peak, yet lacking apical protuberance of first metatarsomere. It differs from P. fraxini and P. kosugii in (1) antennal flagellum distinctly widened apically, apical flagellomere two times as wide as medial width of F1; (2) gena glabrate punctate; (3) mesoscutellum not projected posteriorly; and (4) body orange brown entirely. TYPE MATERIAL: HOLOTYPE: R, Malaysia: Negri S., Pasoh Forest Reserve (forest gap), 1979-II-10, coll. P. and M. Becker (AEI). DISTRIBUTION: Malaysia: Borneo. ETYMOLOGY: From Latin, distinctus, distinct. Paramblynotus fraxinii Yang, 1994 Paramblynotus fraxinii Yang, 1994: 157–164, R; China: Helongjiang; NWCF (HTR, paratype 2RR). FEMALE: Length 4.5 mm. Head, mesosoma, and antenna black. Legs brown except coxae black. Metasoma brown. Wings transparent. Relative size of abdominal T3–T7: 1.9:1.0:1.1:2.4:0.9. Metatarsomere 1mt/2–5mt 5 0.95. MALE: Unknown. Paramblynotus fraxinii is most similar to P. kosugii, but it differs from the latter in (1) mesoscutellum without transverse inflection before the posterior projection, and rounded posteriorly in dorsal view; (2) lateral propodeal carina strongly raised anterodorsally into a lobular process; and (3) size smaller. An additional character to separate P. fraxinii from most other species of Paramblynotus is that the female antenna is 12-segmented. MATERIAL EXAMINED: 1R (paratype), China: Helongjiang, 1989-VI-30, Z. Yang and X. Xu coll. (NWCF). DISTRIBUTION: China: Helongjiang. BIOLOGICAL NOTES: Collected on dead trunk of Fraxinus mandrushica (Oleaceae) infested with Mesosamyops (Cerambycidae) and Tremex simulacrum (Siricidae). (Ronquist, 1995a; Yang and Cui, 1994). Paramblynotus kosugii Watanabe and Sakagami, 1951 Paramblynotus kosugii Watanabe and Sakagami, 1951: 129, =; Japan: Honshu; EIHU (HT=, paratypes 4==). MALE: Length 6.0 mm. Head, mesosoma, and antenna black. Legs brown except coxae black. Metasoma brown. Wings transparent. 1mt/2–5mt50.84. FEMALE: Unknown. Paramblynotus kosugii is most similar to P. fraxinii, but it differs from the latter in (1) mesoscutellum with an inflection prior to the posterior projection, and truncate posteriorly in dorsal view; (2) lateral propodeal carina not raised anterodorsally into a lobular process; and (3) size distinctly larger. MATERIAL EXAMINED: 5== (holotype and 4 paratypes), Japan: Sapporo, 1949- VII-23, K. Kosugi coll. (EIHU). DISTRIBUTION: Japan: Sapporo. Paramblynotus borneanus (Weld, 1922) Paribalia borneana Weld, 1922: 326, =R; Borneo; USNM (HTR, paratype =). Paramblynotus borneanus (Weld) Ronquist, 1994, combination. FEMALE: Length 4.8 mm. Head and thorax black to dark brown; antennae, legs, and metasoma reddish brown. Head, mesosoma, and legs densely pubescent; mesopleural triangle and axillar area with conspicuous pubescence. Wings entirely transparent. Vertex foveate-reticulate. Eye extended laterally beyond outer margin of gena. Ocellar plate distinctly raised, mostly foveate-reticulate, and defined laterally by carina lined along interior side with a row of large foveae. Median frontal carina present between antennal sockets and simple. Upper face foveate-rugose laterally; antennal scrobe distinctly depressed, glabrate with sparse punctures and pubescence, and defined by carina laterally. Gena glabrate with dense punctures and pubescence; lower face and clypeus foveate/punctate-reticulate with

Anterior plate of pronotum glabrate anteromedially and otherwise densely punctate with appressed pubescence. Pronotum with dorsomedial peak distinctly higher than mesoscutum and slightly bent backward apically. Lateral pronotal carina distinct, present only in lower two-thirds. Dorsal pronotal area glabrate, present along anterior third of posterior margin of pronotum. Mesoscutum flat dorsally and transversely costate with superficial foveae set in rows. Mesoscutellum inclined laterally and narrowly rounded posteriorly; lateral dorsal process not raised. Mesopleural triangle conspicuously pubescent. Metepisternum areolate-reticulate in upper part, with a small elevated glabrous area medially, and conspicuously pubescent ventrally. Lateral propodeal carinae strongly curved laterally at middle, and strongly raised anterodorsally into a lobular process with dorsal pubescence; median propodeal area glabrate; median longitudinal carina present anteriorly and two weaker submedian longitudinal carinae present behind median transverse carina. Rs+M of forewing nebulous, arising from middle of basal vein. Marginal cell 3.0 times as long as wide and 1.5 times as long as submarginal cell. Bulla on Sc+R 1 absent. Petiole 0.5 times as long as wide in lateral view. Tergum 8 entirely hidden by T7; relative size of abdominal T3–7: 1.8:1.0:1.0: 3.9:1.9; T3–5 glabrous; T6 mostly glabrous and punctate with a middle transverse band of sparse pubescence dorsolaterally; and T7 densely punctate with anterior band of of conspicuous pubescence dorsolaterally. Apical teeth of metatibia reduced, but distinctly slender and pointed apically. MALE: Length 3.8 mm. MATERIAL EXAMINED: 2: R (type) and = (paratype), USNM. DISTRIBUTION: Borneo. Paramblynotus aptatus, new species FEMALE: Length 3.0 mm. Body entirely black except antenna, base and ventral side of postpetiolar metasoma, fore- and middle leg, and metatarsus brown to dark brown.

Gena glabrate and densely punctate with pubescence; lower face and clypeus foveate/punctate and longitudinally rugose; anterior tentorial pits distinct; clypeo-pleurostomal sulcus and epistomal sulcus form an indistinct, smoothly curved arch.
