Triaenodes tajo , new species
Fig. 24 View FIGURE 24 , 36 View FIGURE 36
This is yet another species similar to T. delicatus , all of which may represent individuals of a highly variable species. However, all of the males of T. tajo studied (n=6) are invariate in their morphology and differ from T. delicatus in the short dorsomesal process of tergum X and the broad lateral flanges basolaterally on tergum X.
Adult (male: n=6, female: n=3). Forewing length 5.7–6.5, 6.0 mm (male), 6.7–7.1 mm (female); hind wing length 4.5–5.3, 4.9 mm (male), 5.4–5.7 mm (female). Eye 0.40–0.42, 0.41 mm wide (male), 0.40–0.43 mm wide (female). Antennal scape 0.42–0.47, 0.45 mm long (male), 0.43–0.47 mm long (female). Maxillary palp segment lengths (in mm): 0.23– 0.27, 0.24; 0.32–0.38, 0.35; 0.40–0.48, 0.43; 0.21–0.24, 0.22; 0.39–0.47, 0.43 (male); 0.27–0.29, 0.42–0.45, 0.50–0.53, 0.24–0.27, 0.55–0.58 (female). Forewing golden brown, with narrow line of cream colored hairs along anal margin.
Male genitalia. Abdominal segment IX anterior margin slightly rounded; pleural region membranous, setose; tergum IX, in dorsal view, with posteromesal margin indistinct, with pair of small dorsomesal papillae; sternum IX in lateral view with posterior margin slightly sinuate. Preanal appendage setose, about as long as wide, constricted basally, apex subacute. Dorsomesal process of tergum X digitate, originating basally, short, less than half length of tergum X, with apical setae; tergum X, in dorsal view, with lateral margins subtriangular, apex rounded; in lateral view, triangular, apex acute, slightly upturned, with broad 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, long, straight, tapering; phalicata troughlike, straight, narrow throughout length, apex mucronate, phallotremal sclerite not evident.
Female genitalia. Abdominal segment VIII with sternum setose posteriorly, pleural region highly membranous. Posterior margin tergum IX triangular in dorsal view, with papillose lobes not evident. Valves heavily setose, rounded. Tergum X setose, triangular in lateral view, ventrolateral margin straight, apex acute; in dorsal view constricted medially, apex rounded. Appendage of segment X setose, broad basally, elliptical. Structures of internal genitalia as in Figs. 36A, C View FIGURE 36 ; vaginal chamber in ventral view circular.
