D. B. BAKER Hope Entomological Collections, University Museum, Oxford, United Kingdom. A NEW GENUS OF NOMADINE BEES FROM NORTH AFRICA (HYMENOPTERA: APOIDEA, ANTHOPHORIDAE) Baker, D. B., 1994. A new genus of nomadine bees from North Africa (Hymenoptera: Apoidea, Anthoporidae). -Tijdschrift voor Entomologie 137: 155-159, figs. 1-4. [issn 0040-7496]. Published 15 December 1994. Aethammobates prionogaster gen. et sp. n. Anthophoridae: Nomadinae) is described from a unique male collected in Egypt. The new genus is referred to the Holcopasitini and its relation-ships with other holcopasitine bees are discussed. D.B. Baker, Hope Entomological Collections, University Museum, Oxford oxl 3pw, U.K. Keywords. — Hymenoptera; Anthophoridae: Holcopasitini; Aethammobates prionogaster, new genus; new species; North Africa. Among a number of epeoline bees received many years ago from the late Prof. Dr. H. Priesner was a single male of a strange nomadine bee that could not be referred to any described genus. A description and figures were prepared, and the specimen was then set aside in the expectation that further specimens, in-cluding possibly the female, would sooner or later come to light. After more than 40 years, this expecta-tion has not been fulfilled, although the locality where the bee was obtained (Gebel el Asfar, near Cairo) was one much visited by both pre-War and more recent local collectors. Since the locality is now being devastated by construction works (C.G. Roche, in litt., 6 September, 1992), making the recovery of further material less likely, and since also the system-atics of the Nomadinae have recently come under re-view by several authors, notably Alexander (1990) and Roig-Alsina (1991), it seems desirable to place the new genus and species on record. Aethammobates gen. nov. Description. — Head in frontal aspect transverse, the eyes rather small, separated by 1.2 times their length, their inner margins convex, subparallel; clype-us short, carinate laterally along epistomal suture, paraocular area adjacent to carina slightly concave and narrowly impunctate; labrum elongate (length to breadth ration 1.44 : 1), apically entire, lacking discal tubercles; antenna] sockets at mid-level of eyes; inter-antennal carina divided, forming a V-shaped protub-erance, the open end of the V upward; facial foveae absent; vertex longer than inter-ocellar distance; pre-occipital ridge carinate; malar area rudimentary. Antennae 13-segmented, scape long (length to breadth ratio 3:1); pedicel free; first flagellar segment long (length to breadth ratio 3:1), equal to segments 2+3; segments 2-10 passing from transverse to quad-rate. Mandibles simple, with weak basal protuberance opposed to lateral termination of clypeal carina; only posterior articulation in contact with eye. Stipital comb absent; maxillary palpi 5-segmented; blade of galea moderately, uniformly sclerotized, acuminate, extreme apex very narrowly rounded. Mesosoma broad, dorso-ventrally compressed. Pronotum with well developed dorsal surface limited anteriorly by an uninterrupted carina; anterior surface broad, flat, rounded abruptly into collum. Mesoscutum little convex; parapsidal lines well marked, about as long as tegula; axillae not protu-berant; scutellum extending laterad slightly beyond axillae, with distinct dorsal and posterior vertical sur-faces separated by a weak, irregular (interrupted by punctation) carina, slightly overhanging subvertical, coplanar surfaces of metanotum and propodeum; omaulus continuous across mesepisternum, forming prominent angles on either side of a median, semicir-cular inflexion; mesepisternum anterior to intermed-iate coxae strongly transverse, transversely concave. Metanotum with prominent lateral lobes. Wings (fig. 4) short, forewing about 0.6 body length. Forewing bare basally, becoming pubescent apically, especially beyond cells; marginal cell broad, rather broadly rounded at apex, apex separated from wing-tip by less than cell length; distal abscissa of Rs absent; two sub-marginal cells, the second much shorter than the first, the first receiving 1 m-cu near its apex, the second 2 m-cu beyond the middle. Hindwine; with jugal lobe 155
