Tetrastichus stramenticius Delucchi (Eulophidae)

Tetrastichus stramenticius Delucchi, 1962d: 378 . Holotype m, Tanzania: Province Morogoro, Bunduki, Uluguru Mts. , middle Mgeta (MRAC [examined]).

Material. HOLOTYPE m (cp, left antenna lacking) labelled` HOLOTYPUS [orange±red, not original]; COLL. MUS. CONGO Tanganyika Terr.: Bunduki Uluguru Mts. , moy. Mgeta 1300 m. 30-IV/ 2-V-1957; Mission Zoolog. I.R.S.A.C. en Afrique orientale (P. Basilewsky et N. Leleup); TYPE [red]; Tetrastichus stramenticius n. V. Delucchi det. ’.

Remarks. According to LaSalle (in litt.) the holotype runs to Pracetus BoucÏek (containing the single species P. longus BoucÏek ) in BoucÏek’s key to Australasian Tetrastichinae (1988: 594) , or Lisseurytomella Gahan and Fagan (containing the single species L. X ava (Ashmead )) in LaSalle’ s key to North American Tetrastichinae (1994: 124) . These three taxa are similar because the antenna is inserted high on the face with the scape exceeding the level of the vertex, they have a distinct rugose petiole, and all funicular segments are very long. T. stramenticius diOEers from both Pracetus and Lisseurytomella in having the propodeum reticulate rather than strongly rugose. Pracetus is similar to stramenticius in having the axillae not strongly advanced so that the scapular ¯ange is broad and triangular, but diOEers in having the antennae composed of four funicular segments and a loosely two-segmented club. Lisseurytomella is similar to stramenticius in having the antenna with three funicular segments and a three-segmented club, but diOEers in having the axillae not advanced so that the scapular ¯ange is linear. Clearly further work is necessary to properly de®ne these taxa. Since this species clearly cannot remain in Tetrastichus , it is provisionally transferred to Pracetus .

Status. Pracetus stramenticius (Delucchi) comb. n.

Trichomalus acuminatus Delucchi and Graham (Pteromalidae) Trichomalus acuminatus Delucchi and Graham, 1956: 548 , 556. Holotype m, Czech Republic: Moravia, Frain [Vranov nad Dyje] (NMW [examined]).

Material. HOLOTYPE m (mp) labelled`3.8.83 Handlirsch; Aus Gymn. villosulus; Trichomalus acuminatus n. m V. Delucchi det. 55; TYPE [red]’.

PARATYPES, NMW: 1 m (mp). MG : 1 m (mp). VD : 1 m (mp), one slide (sc) with left antenna and right fore wing (1956: 553, ®gures 2c±2e) of paratype.

Remarks. A further specimen in VD though properly labelled as paratype was not mentioned by Delucchi and Graham and is therefore not considered as part of the type series.

Status. Trichomalus acuminatus Delucchi and Graham.
