( Fig. 8 )

Cicada obtusa Fabricius 1787: 269 [n. sp.]

Oncometopia obtusa ; Schröder 1959: 17 [listed, described, pl. 1, figs. 1, 2] Cicada obtusa ; Young 1965a: 15 [lectotype designated]

Oncometopia (Oncometopia) obtusa ; Metcalf 1965: 579 [catalogued] Oncometopia (Oncometopia) obtusa ; Young 1968: 227 [listed] Oncometopia (Oncometopia) obtusa ; McKamey 2007: 309 [catalogued] Description. Length of male 11.0– 12.3 mm, female 11.7–12.3 mm. External structure as in O. orbona .

Coloration. Body shape and coloration of examined specimens from Trinidad and Tobago ( Fig. 8 A, B) match well the description of Schröder (1959). Head and thorax with ground color sordid yellow peppered with minute reddish dots, except posterior pronotum and forewings green to purplish brown; black pattern as in O. clarior . Specimens at USNM are dark, reddish-brown, apparently due to post-mortem color change.

Male terminalia. Aedeagus expanded apically, in caudal view with narrow fleshy border ( Fig. 8 C, D), otherwise similar to O. clarior . Pygofer process ( Fig. 8 E) as in O. clarior , other characters as is typical for the group (see O. orbona ).

Female terminalia. Similar to O. clarior specimens from Oaxaca, with posterior extension of vestibulum short and wide, its apex broadly rounded ( Fig. 8 H).

Types. The lectotype, male, in the collection of the Zoologisches Museum der Universität Kiel (ZMUK), Germany, has been designated by Young (1965a) and was not examined in this study. According to Schröder (1959), who examined the specimen, the type locality is Cayenne in French Guiana.

Material examined. Trinidad and Tobago: Trinidad: [no locality], xii.1902, [no collector] [2♀, USNM] ; St. Augustine , 12.xii.2003, V. Thompson [1Ƌ, INHS] ; Tobago: Friendship Estate , 07.ix.1918, H. Morrison [1Ƌ, USNM] .

Distribution. Young (1968) listed the species from Colombia, Venezuela, Trinidad Island, and Suriname. It is also known from French Guiana ( Schröder 1959) and Tobago Island.

Notes. The species is close to O. clarior , being distinguished by the aedeagus expanded in the apical part ( Fig. 8 C).
