Argogorytes matangensis (Turner)

Gorytes matangensis R. Turner 1914:252, ♀. Holotype: ♀, Malaysia (East): Sarawak: Matang (BMNH), examined. - Maidl and Klima 1939: 55 (in catalog of world Astatinae and Bembicinae ). - As Argogorytes matangensis : R. Bohart and Menke 1976: 492 (new combination, listed).

Malaygorytes konishii Nemkov 1999:3 ♀. Holotype: ♀, Malaysia: Malay Peninsula: Nageri Sembilan: Pasoh Forest Reserve (National Institute of Agro-Environmental Sciences, Tsukaba, Japan), not examined. New synonym. - As Argogorytes konishii : Nemkov and Pulawski 2009: 11 (new combination, in cladistic analysis of Gorytini ).

The only female of this species in the CAS collection agrees to perfection with the type of Argogorytes matangensis and both specimens fit very well the good description of Malaygorytes konishii by Nemkov (1999). Their three most important characters are: scutellum with round preapical fossa whose diameter is about half midocellar width ( Fig. 1a ), terga II-V narrowly double-edged, and a narrow apical fascia of golden setae present on each terga I-IV ( Fig. 1e ). Other significant features include: basal scutellar sulcus foveolate ( Fig. 1a ); postscutellum longitudinally ridged ( Fig. 1a ); mesopleuron with conspicuous longitudinal ridges that do not extend down to mesopleural signum ( Fig. 1b ); metapleuron microscopically punctate; tergal punctures minute; tergum I with erect setae, the longest ones (on the tergum’s side) slightly longer than midocellar width; median carina of sternum I triangular in profile; sternum II moderately angulate anteromesally, with fine, dense, and larger, sparse punctures; sterna III and IV punctate throughout (punctures conspicuous and sparse mesally); pygidial plate unusually narrow, practically parallel-sided, with glabrous median carina ( Fig. 1d ); body all black except at least hindfemur reddish brown (all femora reddish brown in holotype of matangensis; mid- and hindfemora reddish brown in CAS specimen), wings mostly hyaline but marginal cell and beyond conspicuously infumate as well as anterior portions of submarginal cells II and III ( Fig. 1c ). Length 11.1-11.4 mm.

Male unknown.

Argogorytes fuliginosus Tsuneki, 1968, from Taiwan, whose type I have also examined, is similar to matangensis in having double-edged terga and a small preapical fossa on the scutellum as well as a conspicuously ridged mesopleuron. It differs in having the mesopleural ridges attaining the mesopleural signum, the legs all black, and all wings conspicuously infumate.
