Triaenodes guadaloupe , new species

Fig. 14

This is a distinctive species among those that lack the apicoventral projection on the inferior appendage. It is most similar to T. morai in the possession of a spatulate dorsomesal process of tergum X, but differs from that species in its much larger size (7.4 mm vs. 5.3 mm forewing length in T. morai ), by having 2 instead of 3 parameres, and by having both shorter preanal appendages and apex of tergum X.

Adult (male: n=1). Forewing length 7.4 mm, hind wing length 5.4 mm. Eye 0.38 mm wide. Antennal scape 0.38 mm long. Maxillary palp segment lengths (in mm): 0.26, 0.35, 0.50, 0.27, 0.65. Forewing pale yellow, denuded.

Male genitalia. Abdominal segment IX anterior margin nearly straight; pleural region membranous, sparsely setose (or not evident); tergum IX, in dorsal view, with posteromesal margin rounded, dorsomesal papillae not evident; sternum IX in lateral view with posterior margin slightly sinuate. Preanal appendage setose, shorter than wide, broad basally, apex rounded. Dorsomesal process of tergum X spatulate, originating medially, short, extending to apex of tergum X, with apical setae; tergum X, in dorsal view, with lateral margins sinuate, apex slightly excavate medially; in lateral view, parallel sided, apex truncate, apicolateral margins without microtrichia (or not evident). Inferior appendage rounded basally, setose, with sharp apicolateral flange, without apicoventral projection; recurved process abruptly downturned subapically, narrow, tapering throughout length, apex sharply attenuate, with subbasal flange; apicomesal lobe heavily setose, elongate, narrow, parallel sided. Phallobase small, triangular, endothecal membranes prominent, highly convoluted, with single, curved paramere; phalicata troughlike, gently curved, narrow throughout length, apex with very slight cleft, phallotremal sclerite not evident.

Holotype male: PANAMA: Chiriqui: Guadalupe Arriba , 08°52’26”N, 082°33’13”W, 19–25.vi.1985, H Wolda ( UMSP000027126 ) ( NMNH).
