Tettigia pennata Distant 1881: 11 (type material in BMNH). Cicada pennata Metcalf 1963b: 800.
Type locality. Senahu, Guatemala.
Remarks. While preparing this work, another of the species currently assigned to Cicada Linnaeus, 1758 was investigated in an to attempt to place it in the correct genus. The morphology of this species is significantly different from the Old World genus Cicada, the senior synonym of Tettigia Kolenati, 1857 (Sanborn 2013). Distant (1881) discussed the incongruent distributions of the genera, the fact that many species appear not to belong to the genera, and distinguished Tettigia from Cicada only by the proportions of the basal cell of the fore wing. The general characteristics of the female specimen to which he had access may have left him no other option as to where to classify the species based on the available Neotropical genera of the time. However, the small head with globose eyes much narrower than the base of the pronotum but projecting beyond the anterior angles of the pronotum, the frons deflected ventrally to the frontoclypeal suture, the distance between ocelli being less than the distance between lateral ocelli and eyes, postclypeus and supra-antennal plates broadly rounded, the rostrum reaching beyond the posterior coxae, the lateral margins of the lateral angle of the pronotal collar ampliate but lateral pronotal margins not ampliate, length of pronotum less than length of mesonotum, mesonotum obscuring the dorsal metanotum, opercula not expanding beyond the base of the abdomen, the venation and infuscation pattern on the fore wings, the clear basal cell, and the notched sternite VII of the female combine to place the species in the genus Neocicada as the genus was defined by Sanborn et al. (2005). The species is reassigned here to Neocicada to become Neocicada pennata (Distant 1881) n. comb. The species shares characteristics of both N. australamexicana and N. centramericana in the key to the genus produced by Sanborn et al. (2005) but differs from both species morphologically. In addition, N. pennata n. comb. is distributed south of the known range of N. australamexicana and west of the known ranges of N. centramericana (Sanborn et al. 2005). Specimens of another Neocicada species, N. australamexicana, were also classified by Distant in Tettigia (Sanborn et al. 2005) further illustrating the similarities in their morphology.
Distribution. The only known specimen is the holotype recorded from Guatemala (Metcalf 1963b; Sanborn 2013).
Subfamily CICADETTINAE Buckton, 1889
Tribe ARAGUALNINI n. tribe
Type genus. Aragualna Champanhet, Boulard & Gaiani 2000: 42 (Venezuela).
Remarks. The genus Aragualna does not possess the morphological characters necessary to be classified in the Cicadinae or the Dazini. Aragualna plenalinea Champanhet, Boulard & Gaiani, 2000 was placed in the tribe Dazini when it was described (Champanhet et al. 2000). However, it differs significantly from the other Dazini in terms of its morphology. The single species of Aragualna exhibits the following characteristics of the Cicadettinae as defined by Moulds (2005): the metanotum is visible at the dorsal midline, the supra-antennal plate extends most of the distance to the eye, fore wing cubitus posterior + anal vein 1 fused for most of their lengths, hind wing radius posterior and median veins are fused at their base, timbal cavity lacking a turned-back rim or timbal cover, pygofer distal shoulder undeveloped, pygofer upper lobe present, uncus small and flat, and large claspers dominating abdominal segment 10 (Fig. 1). As a result, the species cannot remain within the Dazini in the Cicadinae and a new tribe is necessary for the genus within the Cicadettinae.
The Aragualnini n. tribe is hereby erected for the genus Aragualna within the Cicadettinae. The name is derived from the only genus, Aragualna Champanhet, Boulard & Gaiani, 2000, currently assigned to the tribe. Characteristics of the new tribe include the lateral margins of the pronotum extend from the lateral angle of the pronotal collar and are angled to the lateral eye, head narrower than pronotum anterior margin and mesonotum, postclypeus truncated anteriorly, opaque fore wings with the nodal line forming an arching transverse nerve from the node to nodulus at the junction of cubitus anterior 2 and cubitus posterior + anal vein 1, distal hind wing cubital cell 1 less than half the width of distal cubital cell 2, metanotum completely visible dorsally, abdomen wider than pronotum, large timbals extending ventrally ventral to wing bases, male opercula reduced, claspers large, forming a tubular encapsulation for the aedeagus.
Within the Cicadettinae, the Aragualnini n. tribe can be distinguished from the Lamotialnini Boulard, 1976 and the Ydellini Boulard, 1973 by possessing timbals and the lateral dilation of the pronotum that are lacking in the species of these tribes. The Carinetini Distant, 1905b can be distinguished by the lack of ampliate lateral pronotal margins and hyaline fore wings lacking the obvious nodal line. The fore wing veins of the Hemidictyini Distant, 1905e form a meshwork of irregular cells producing a reticulated pattern on the fore wing not found in the new tribe. The Tettigomyiini Distant, 1905e possess an inflated abdomen and the hyaline fore wings are not much longer than and sometimes shorter than the abdomen. The head is slightly narrower than the mesothorax, the lateral pronotal collar is not ampliated and confluent to the pronotal sclerites, the fore wing costa is widest at the node, the male abdomen is inflated with a central dorsal ridge and the aedeagus is S-shaped in members of the Chlorocystini Distant, 1905f. The Cicadettini Buckton, 1889 lack the ampliated lateral pronotal margins, the head is about as wide or wider than the maximum width of the pronotum, and the median and cubitus anterior veins of the fore wings are fused or coalesced at the basal cell. Species of the Taphurini Distant, 1905g have a head wider than the pronotum, the pronotum lateral margins are not ampliate, the pronotum is subquadrate and not distinctly narrowed anteriorly. The Parnisini Distant, 1905f have hyaline fore wings, a subquadrate pronotum, and an abdomen that is shorter than the distance between the apex of the head and posterior cruciform elevation. Finally, the Prasiini Matsumura, 1917 possess a very narrow vertex, a large obconical and triangularly protruding postclypeus, and the lateral lobes of the male pygofer have well-developed and posteriorly projecting protuberances all of which are absent in the new tribe.
Genus included. The tribe is represented currently only by the type genus Aragualna.
