Manzumbadoa bradysioides sp. n.

( Figs 1-8 )

Description (for characters not mentioned here, see genus description above)

Male. Body length: 2.9-3.1 mm. Head: Antenna with fourth flagellomere 2.2 times as long as wide ( Fig. 1 ). Maxillary palpus as in Fig. 5 .

Legs: Fore tibia with anteroapical depression bearing distal comb of some 20 setae ( Fig. 2 ). Wing: See Fig. 3 .

Terminalia: Gonocoxites ( Fig. 6 ) with setae of various lengths; with megaseta each ventro- and dorso-distally. Gonostyli ( Figs 6, 7 ) elongate, in distal half tapering to tip, inside and distally with very short setae and long setae elsewhere, with 1 short, thick spine outside subterminally and 3 spines in line apically. Ejaculatory apodeme ( Fig. 8 ) as long as tegmen. Tegmen ( Fig. 8 ) with long, sclerotized ventral apodemes, membranous elsewhere and wrinkled laterally. Tergite 9 ( Fig. 4 ) with setae of various lengths, in distal third very weak and lacking setae and trichia. Tergite 10 ( Fig. 4 ) extending distolaterally beyond tergite 9. Cerci ( Figs 4 , 8 ) large, setose, rounded terminally. Hypoproct ( Fig. 8 ) weak, two-lobed, with 2 setae each.

Female. Vor characters not mentioned here, see the above description of the male.

Body length: 3.0 mm.

Abdomen: Segments 1-6 much broader than following segments. Terminalia: Without striking features that deviate from those in other sciarids.

Etymology. The species epithet ‘bradysioides’ indicates the similarity between the new species and typical species of the genus Bradysia , a fact that is most strikingly expressed in the outline of male terminalia.

Types. Holotype: Male, Costa Rica, Puntarenas province, Corcovado National Park , Cerro Rincón, La Tigrilla, 600 m above sea level, 7 Feb.-23 April 2002, by Malaise trap, J. AZOFEIFA (sample no. INBio 70848 ) . Paratypes: 1 male, same data as the holotype ; 2 males, 1 female, Corcovado National Park , Cerro Mueller, 744 m above sea level, 20 Dec. 2001 - 7 Feb. 2002, by Malaise trap, J. Azofeifa (no. 67160) ; 2 males, same locality as the holotype , but 20 Dec. 2001 - 7 Feb. 2002 (no. 67158).

Other material studied. 1 male (in ethanol), Corcovado National Park, 800 m S Cerro Rincón, 745 m above sea level, 20 Dec. 2001 - 7 Feb. 2002, by Malaise trap, J. AZOFEIFA (no. 67159).
