Jeepiulus flauus gen. nand sp. n. (Hemiptera, Auchenorrhyncha, Cicadellidae) is described from Mato Grosso and Rondonia, Brazil. This genus is similar to Alocha Melichar andAlbiniana Cavichioli, however, Jeepiulus gen. n. has its head produced and male genitalia with paraphyses. Key words: Auchenorrhyncha, Cicadellidae, Jeepiulus gen. n., J. flauus sp. n. Introduction The  Paromenia genus group was established  by Young  (1977)  with  11  genera.  Cavichioli  (1996) revalidated Alocha Melichar, 1926 and described Albiniana, the latter with one species, Paromenia weyrauchiYoung, 1977, increasing the members of this genus group to 13 genera. Study of specimens from west-central and northern Brazil shows that these possess paraphyses (structures of the male genitalia that are situated between the connective and the aedeagus), a characteristic that  is not found inParomenia,Alocha, andAlbiniana, butis present in Dasmeusa Melichar. However, the general exter-nal structure of these specimens is not similar to Dasmeusa, being closer to that of Alocha and Albi-niana. For these reasons, a new genus is proposed, Jeepiulus gen. n., with one species, J. flavus sp. n. Jeepiulu8 gen. n. Type-species: Jeepiulus flavus sp. n. Description:  Head  produced,  anterior  margin broadly round,  without carina at transition be-tween crown and face; ocelli located on a line be-tween angles of anterior eyes; dorsal surface smooth, with a  fovea between ocelli and eyes; front-genal suture (lateral clypeal suture of Young, 1977) ex-tending onto crown and almost attaining ocelli; antennalledges not protuberant, anterior margins oblique in lateral view and without carina; front (sensu Mejdalani, 1998) convex in profile, arched; clypeus (clypellus of Young,  1977) continuous to front, with apical margin truncate; fronto-clypeal suture medially obscure. Pronotum  as  wide  as  head,  lateral margins slightly convergent anteriorly and posterior margin weakly emarginate  medially;  notopleural carina complete. Forewing almost 4 times its largest width; venation distinct with veins not elevated; with four apical cells, base of third cell more proximal than base of fourth; anteapical cells closed with bases more basal than claval apex. Hindwing almost as long as forewing when at rest. Hindleg with femoral setal formula 2.1.1; first tarsomere of the hindleg longer than combined length of second and third tarsomeres, with two rows of  very short weak setae on plantar surface. Pygofer, in lateral view, almost as wide as long; without process, posterior margin truncate. Sub-genital plate, almost as long as the pygofer, triangu-lar,  bipartite.  Style long,  apically truncate with preapicallobe. Connective short, T-shaped, keeled. Aedeagus subcylindrical, slightly flattened lateral-ly and with apical process. Paraphyses symmetri-cal. Female abdominal sternum VII short with pos-terior margin truncate and with a median emargin-ation. Second valvulae expanded beyond basal cur-vature, with subquadrangular teeth in the dorsal margin, apex slightly angulate dorsally and with a preapical prominence in the ventral margin. Comment. Jeepiulus gen. n.  is closely related to Alocha Melichar and Albiniana Cavichioli by pos-sessing the apical margin of the clypeus truncate, and by its external appearance and coloration. It may be distinguished by having anterior margin of 222  Volume 14, No.4, December, 2000, INSECTA MUNDI 1  8 Figure 1- 9. Jeepiu/us flauus sp.n. 1. Head, pronotum and scutellum, dorsal view; 2.

INSECTA MUNDI, Vol. 14, No.4, December, 2000 the head strongly produced and paraphyses present in the male genitalia. The paraphyses are present  in Das  meusa Melichar, even so in the general aspect it differs mainly in the form of the head. Jeepiulus gen. n. is included in the Paramenia genus group of Young (1977), by possessing style apically truncate, connective with dorsal keel and characters used in the description.

Description: Holotype,  male. Measurements (in mm), total length:  10.60; median length of head: 1.00; transocular width: 2.32;  interocular width: 1.56;  median length of pronotum: 1.48; width be-tween the humeri: 2.32; median length offorewing: 8.60; forewing width: 2.20. Total length of the allo-type: 11.20. Head, in dorsal view, produced, almost triangular, median length 4/10 of the interocular and 6/10 of  the transocular; anterior margin broadly round, almost angulate; dorsal surface without  sculp-ture and with shallow fovea  between ocelli  and anterior angles of eyes;  ocelli on a  line between anterior angles of  eye, closer to the posterior margin than to the lateral borders; antennalledges evident dorsally, in lateral view, slightly oblique and with-out carina;  frontogenal  suture extending to  the crown and almost attaining the ocelli; frons swollen, profile arched, with muscle impressions nitid, con-vex in frontal view; clypeus in profile, continuous to front, with a little median elevation; frontoclypeal suture  incomplete  and  apical  margin  truncate. 223 Pronotum as wide  as transocular width;  lateral margins convergent anteriorly and posterior mar-gin with a slight median emargination; dorsal sur-face without sculpture and pubescence; notopleural carina complete. Scutellum wider than long  basally, non-striate behind transverse sulcus. Forewing al-most 4 times longer than wide; veins not elevated and distinct venation; with four apical cells, base of third cell more proximal than base of fourth; with three anteapical cells  closed,  with bases  not as proximal as claval apex. Hindwing almost as long as the forewing and with R2+3 incomplete. Femora and tarsomeres of the hindleg as the generic descrip-tion. Pygofer, in lateral view, almost as wide as long, posterior  margin truncate,  without  process  and macro  setae in the third apical.  Subgenital plate triangular,  bipartite,  2/3  length  of  the  pygofer, abruptly grooved from the middle to apex, with a lateral postbasallobe and with rows of macrosetae in the lateral margins. Style as long as basal rami of the paraphyses, apically truncate in foot-shaped and with preapical lobe.  Connective inverted "T-shaped" with a strong dorso-median carina. Aedea-gus subcylindrical, slightly flattened laterally, with a  dorso-basal lobe, apically dilated, with a  short unciform process in the apico-ventral margin and one row of denticles located in the ventral margin next to the apex. Paraphyses symmetrical, basal rami very short and with two slender apical rami, which are long, parallel, and dorsally curved. Allotype (female). Body longer and morpholog-ical characters similar to holotype (male). Pygofer long, apically angulate, macrosetae located on the ventral margin of apex. Sternum VII subrectangu-lar, wider than long, posterior margin tetralobate and with the lateral lobes  more  produced than median lobes. Second valvulae (nine valve, sensu Mejdalani, 1998), broadening after the basal curva-ture,  with  subquadrangular teeth in the  dorsal margin; apico-ventral margin angulate and with a pre  apical prominence at the apico-ventral margin. Coloration. Dorsally and ventrally yellow, pos-terior margin of the pronotum and scutellum pale yellow. Forewing with a narrow orange strip, half-moon shaped, located in the apical margin next to the apical cells and with the first apical cell hyaline. Comments. Jeepiulus flavus  sp.  n.  is similar to Alacha sardida  (Signoret,  1854)  in the external aspect, but differs by having the head more pro-duced, dorso-ventrally flattened and male genitalia with paraphyses. 224  Volume 14, No.4, December, 2000, INSECTA MUNDI Acknowledgements This  research  was  supported by  Fellowship CNPq 301527/85-7.
