Manota squamulata sp. n. ( Fig. 7 )

Description. Small species.

Male. Head. Antenna with fourth flagellomere 1.8 times as long as wide. Maxillary palpus with third palpomere bearing (3–)4(–5) curved sensilla; fourth palpomere with a small process apically.

Thorax. Anterior basalare and laterotergite each setose. Episternum 3 with ventral portion setose. Wing. Length 1.5 mm. Membrane with a few setae along posterior margin. Sc bare. CuA2 fading away proximally.

Terminalia ( Fig. 7 ). Sternite 9 largely merged with gonocoxites; only posterior margin distinct, situated at almost same level as posterior gonocoxal margin, straight or very slightly emarginate; on interior surface with extensive scale­like pattern; on exterior surface densely covered with setae, sometimes with a small non­setose area medially. Distolateral lobes of gonocoxites absent. Gonocoxites in position I+II with 12–14 thick, blunt and pointed setae on lobe; in position III+IV with 1 pointed megaseta. Gonostyli short, slightly bilobed; ventral lobe on inner margin with some 5 large setae increasing in length posteriorly; dorsal lobe on posterior margin with some 4 large setae curved dorsally. Parastylar lobes large, rounded; each with some 5 setae posteriorly. Tegmen strongly narrowed in distal half, very wide basally with dorsal portions of tegmen extending laterally beyond width of parameral apodemes. Hypoproct tapering to tip; with long setae disto­laterally.

Diagnostic characters. Together with M. major (next species), this is the only species with both the anterior basalare and laterotergites setose. The terminalia with sternite 9 are largely merged with the gonocoxites and with a scale­like pattern on the interior surface; disto­lateral lobes of the gonocoxites are absent; gonostyli are stout and with large setae apically; and the parastylar lobes are large and setose.

Etymology. From Latin, squamulatus, with small scales, referring to the interior surface structure on sternite 9.

Types. Holotype. Male, Costa Rica, Limón province, Hitoy Cerere Biological Reserve, Sendero Espavel , 100–550 m, in tall secondary rain­forest, 18 Sep.–7 Oct. 2003, by sweepnet and aspirator, M. Jaschhof . Paratypes. 1 male, same data as the holotype ; 2 males, same data , but 550 m, by Malaise trap, E. Rojas, B. Gamboa, W. Arana, M. & C. Jaschhof; 1 male, Puntarenas province, Cerro Puma , 100–300 m, 19 June–8 July 2003, by flight interception trap, M. Moraga, A. Azofeifa & K. Caballero ( INBio sample #74480) .
