ROVARTANI KÖZLEMÉNYEK XLV. 1 1984 p. 41-44 A new genus and a new species of crickets (Orthoptera: Gryllidae, Gryllinae) from Africa By A. V. GOROCHOV {Received 4 May, 1983) Abstract: Pollogryllus gen.n. (type-species: Gryllus fuligtnatus Chop.) and Platy- gryllus congolensis sp. n. are described. The new genus is related to Scapstpedus Sauss. and Plebelogryllus Rand, but distinct from both by some peculiarities of male genitalia. The new species differs from all other species of the genus Platygryllus Chop, by its simple spermatophore sack. This paper is based on unidentified cricket material of the Hungarian Natural History Museum (Budapest). Author is very grateful to Dr. H. STEINMANN for the loan of this material. Genus Pollogryllus gen. n. Type-species: Gryllus fullginatus Chopard, 1961. Size small or medium for the subfamily. Body rather stout, pubescent. Head round, shining, uniformly dark without pattern. Frons between antennae noticeably wider than antennái pocket. Clypeofrontal suture feebly curved. Oculi rather large. Ocelli disposed in the form of triangle. Pronotum transverse, with almost parallel lateral sides, pubescent and unicoloured. Male elytra with 2-3 curved oblique veins and rather small quadrangular mirror (Fig. 2). Female elytra with cellular venation at the dorsal field. Legs rather stout, pubescent and unicoloured. Anterior tibiae with large oval external tympanum and very small internal one. Male genitalia rather short (Figs 3-6). Eplphallus short, with 3 short projections at the posterior edge and 2 rather long apodemal processes at the anterior edge. Ectcparameres stout, with narrow semimembranous mesal lobes. Endoparameres long, with small apodema at the base. Virga rather wide, almost straight.Spermatophore sack rather small, with very large superior apodema. Included species: Modicogryllus nlgrodorsatus Chopard, 1961 and possible Gryllulus obscuripennis Chopard. 1938. Diagnosis. General aspect as In the genus Modicogryllus Chop., but head without pattern and male genitalia with simple ectcparameres. Pollogryllus gen. n. is related to Scapslpedus Sauss. and Plebeiogryllus Rand, but distinct from both by habitus and peculiarities of male genitalia (spermatophore sack with large superior apodema, but virga without strong widening at base).
