Manota spinosa sp. n. ( Figs 1A , 11 )

Description. Small species.

Male. Head. Antenna with fourth flagellomere 1.5 times as long as wide ( Fig. 1A ). Maxillary palpus with third palpomere bearing 3 curved sensilla; fourth palpomere with a parasegment or small process apically.

Thorax. Anterior basalare bare. Laterotergite setose. Episternum 3 in ventral portion with up to 3 setae. Wing. Length 1.4–1.7 mm. Membrane without setae. Sc bare. CuAfork complete. Setae on CuA2 and A2 absent or very few.

Terminalia ( Fig. 11 ). Sternite 9 with posterior margin and portions of lateral margins distinct; posterior margin emarginate medially. Ventro­lateral lobes of gonocoxites with 2 small, curved setae interiorly on a separate rim. Disto­lateral lobes of gonocoxites large; inside distally with some 20–25 short, very thick setae; at base with numerous long, fine, curly trichia presumedly belonging to parastylar lobes. Gonocoxites in position I+II with some 15–20 short, stiff setae on lobe; in position III with 1 short, flat, crescent­shaped megaseta plus 2 short, pointed setae; in position IV with 2 thick, blunt megasetae. Gonostyli small, flat, subrectangular in ventral view; each ventro­anteriorly with 4 setae, dorsoposteriorly with 3 setae directed dorsally with one seta particularly strong and re­curved. Parameral apodemes widely spread. Tegmen with ventro­lateral lobes large and very distinct. Hypoproct almost pointed apically; laterally with long setae. Tergite 9 present as a very weak, bilobed plate with strongly sclerotised anterior margin; in holotype specimen even with large setae.

Diagnostic characters. Among the species with setose laterotergites, it has the terminalia quite distinct because of the presence of numerous short, thick setae inside on the disto­lateral lobes of the gonocoxites.

Etymology. From Latin, spinosus, spiny, referring to the dense covering of thick setae on the gonocoxites.

Types. Holotype. Male, Costa Rica, Puntarenas province, Corcovado National Park, 600 m S Cerro Rincón , 745 m, 23 April–24 June 2002, by Malaise trap, J. Azofeifa ( INBio sample #70842) . Paratypes. 10 males, same data as the holotype .
