Conostigmus bakeri Kieffer, 1908

Species Comments and History. Kieffer (1908) described the species from specimens collected in Claremont and San Mateo, California. The description in Kieffer (1908) specifies that the “scape a peine egal aux articles 2 et 3 reunis; troisieme article trois fois aussi long que gros; quatrieme deux fois; dixieme a peine plus long que gros” (pg. 36). Other than these antennal characters, Kieffer describes the specimen as being black, smooth and shiny, with the wings slightly brownish in color and an indistinct facial pit present. Kieffer (1914) keys out the male and redescribes the species, adding that the preoccipital furrow is absent, as with Conostigmus bacilliger .

The location of Kieffer’s specimens is unknown, and the characters given in the original description could apply to several species. For now, we consider Conostigmus bakeri as a species inquirenda.
