Mycetocylapus Poppius 1914: 125, type species: Mycetocylapus major Poppius, 1914 (original designation) Mycetocylapus: Bergroth 1920: 73; Carvalho 1952: 49, 1955a: 21, 1956: 15, 16, 1957: 32; Carvalho & Lorenzato 1978: 123, 124; Schuh 1995: 31; Gorczyca 2000: 51, 2006: 53; Wolski 2008: 156
Diagnosis. Recognized by having labrum in males without spines; anterior lobe of pronotum more or less distinctly narrowed as seen from above (Fig. 2); posterior lobe impunctate (Figs. 2, 5 A); hemelytron covered with shallow and sparsely distributed punctation; endosoma with single, broad sclerite along its length (Fig. 6 B). This genus is most closely related to Proamblia, both sharing a declivous head, broad maxillary and mandibular plates (Figs. 5 A, 7A), and an almost vertical clypeus; but Mycetocylapus can be easily distinguished by the punctation of the hemelytron and an impunctate pronotum, more or less distinctly narrowed at the posterior lobe.
Redescription. Female. Macropterous, suboval. COLORATION (Fig. 2 E–G). Varying from yellow with brownish and reddish areas to castaneous. STRUCTURE AND VESTITURE (Figs. 2 E–G, 4A, 5). Dorsal surface shining, covered with sparse, fine, decumbent setae. Head. Declivous, short in dorsal view, covered with fine, short, decumbent setae; vertex slightly rounded; frons distinctly rounded; clypeus almost vertical, covered by setae somewhat denser than those on vertex and frons; maxillary and mandibular plates broad; gula with bundle of relatively long, semidecumbent setae; antenniferous tubercle almost contiguous with margin of eye; antenna thin; antennal segment I cylindrical; segment II slightly thickened toward apex, covered with relatively dense, semidecumbent setae; segments III and IV covered with relatively long, dense, semidecumbent setae; rostrum long, reaching beyond metacoxae. Thorax. Pronotum. Trapezoidal; anterior lobe narrower than posterior lobe, calli moderately elevated; posterior lobe impunctate, sometimes slightly rugose. Mesoscutum and scutellum. Scutellum flattened. Thoracic pleura. Proepimeron impunctate, smooth; remaining pleura rugose. Hemelytron. Shallowly and sparsely punctate, sometimes rugose, without any punctures; lateral margins rounded, narrowed, almost parallel basally. Legs. Relatively long, covered with rather short, semidecumbent setae; claw not toothed subapically.
Male. Similar to female. Antennal segment I thickened at basal two-thirds (Fig. 5 C); segment II rather stout, bent medially, inner surface covered with very dense, minute, apically curved setae (Figs. 4 A, 5F); lateral margins of hemelytra parallel.
Male genitalia (Fig. 6). Right paramere: paramere body devoid of setae or with several setae; apical process reduced; left paramere with extreme apex of apical process somewhat long; paramere body with only few setae; endosoma with a single, broad sclerite medially; sclerotized portion of ductus seminis inside endosoma long.
Female genitalia. Not examined.
Remarks. I did not have access to the type specimens of M. major and M. minor. They were loaned from the Zoological Museum, University of Helsinki, Finland, several years ago and have not been returned. No information on the specimens has been published since they were loaned from the museum. I found two male specimens belonging to M. minor and one female representing M. major in the material deposited at the National Museum of Natural History, Smithsonian Institution, Washington D.C., USA. The data on the label attached to the specimens are the same as in the type material. They were determined by B. Poppius himself. Therefore, I have decided to redescribe both species on the base of the specimens given above.
