Triaenodes woldai , new species

Fig. 29 View FIGURE 29

While the inferior appendage of this new species is similar to that of T. delicatus and others in the genus, tergum X of T. woldai is unique in two characteristics: the apex is upturned and attenuate and the dorsomesal process is represented by a low setose mound.

Adult (male: n=6). Forewing length 4.3–5.3, 4.8 mm; hind wing length 3.3–4.2, 3.7 mm. Eye 0.35–0.37, 0.36 mm wide. Antennal scape 0.37–0.42, 0.39 mm long. Maxillary palp segment lengths (in mm): 0.24–0.29, 0.26; 0.26–0.35, 0.31; 0.32–0.42, 0.37; 0.18– 0.21, 0.19; 0.35–0.39, 0.37. 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 indistinct, with pair of bulbous dorsomesal papillae; sternum IX in lateral view with posterior margin sinuate. Preanal appendage setose, about as long as wide, constricted basally, apex subacute. Dorsomesal process of tergum X a small setose medial protuberance; tergum X, in dorsal view, with lateral margins subtriangular; in lateral view, narrowly triangular, apex acute, upturned, with lateral flange, apicolateral margins with microtrichia. Inferior appendage subquadrangular basally, setose, with tapering apicoventral projection; recurved process gradually downturned, narrow, tapering throughout length, apex attenuate; apicomesal lobe heavily setose, elongate, narrow, parallel sided. Phallobase small, triangular, endothecal membranes prominent, highly convoluted, with pair of parameres, parameres subequal, one long, curved, tapering secnd shorter, gently curved, tapering, both with microtrichia; phalicata troughlike, gently curved, narrow throughout length, apex acute, irregularly serrate, phallotremal sclerite small, u­shaped.
