Triplocania huitota n. sp.

( Figs 164–175 )

Diagnosis. Related to T. inpa Silva-Neto et al. , and T. fapeam Silva-Neto et al. , differing from them in details of the hypandrium ( Fig. 168 ) and phallosome ( Fig. 169 ). Posterior endophallic sclerites independent, near the distal ends of the external parameres, each with a large proximal tooth on inner border, and three distal teeth; anterior endophallic sclerites with outer arms stout, bow-shaped, and inner arms triangular, anteriorly crenulate; mesal sclerite deeply concave in the middle, with anterior arms acuminate and posterior arms distally forked ( Fig. 169 ).

Male. Color (in 80% ethanol). Body pale brown. Compound eyes brown; ocelli hyaline, with ochre centripetal crescents. Head pattern ( Fig. 166 ); postclypeus with small brown spots; anteclypeus, labrum, genae, antennae and maxillary palps pale brown, Mx4 dark brown distally. Thorax pale brown, with tergal lobes of meso- and metathorax dark brown, pleura with some cream spots. Tibiae and tarsi pale brown, coxae and trochanters cream, femora cream proximally and pale brown distally. Forewings ( Fig. 164 ) with pale brown band proximally on pterostigma; a marginal band from R2+3 to Cu1a; cu1 brown, brown spots at vein ends. Hindwings ( Fig. 165 ) mostly hyaline. Abdomen pale brown, with subcuticular pale brown spots in sternites and part of tergites. Hypandrium, clunium, epiproct and paraprocts pale brown, with small subcuticular areas pale brown. Phallosome dark brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 166 ): H/MxW: 1.47; H/D: 2.59, IO/MxW: 0.75, MxW/IO: 2.00. Vertex slightly above the level of the compound eyes. Outer cusp of lacinial tips broad, with six denticles. Mx4/Mx2: 1.27; Mx4/Mx3: 2.85. Forewings ( Fig. 164 ): L/W: 2.42, pterostigma: lp/wp: 3.58; areola postica elongate, slanted posteriorly, la/ha: 1.64. Hindwings ( Fig. 165 ): l/w: 2.84. Central sclerite of hypandrium wide, straight anteriorly ( Fig. 168 ), with postero-lateral processes blunt ended. Phallosome V-shaped anteriorly ( Fig. 169 ), external parameres membranous, distally rounded and sclerotized, with row of small teeth on outer border; inner border with small sclerotized process. Paraprocts broad, oval ( Fig. 167 ), with posterior margin broadly rounded, with abundant medium and short sized setae in the posterior third and distal border, a macroseta near each sensory field, other setae as illustrated; sensory fields with 26 trichobothria on basal rosettes. Epiproct semioval ( Fig. 167 ), anteriorly convex, with three mesal setae, one to two lateral macrosetae, posterior border with a field of microsetae and 4–5 medium sized setae.

Female. Color (in 80% ethanol). Same as in the male. Head, thorax and subgenital plate pale brown, slightly more pigmented on sides. Gonapophyses and IX sternum brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 172 ): H/MxW: 1.48, H/D: 2.76, IO/MxW: 0.75, MxW/IO: 1.93. Outer cusp of lacinial tips broad, with six denticles; Mx4/Mx2: 1.13. Forewings ( Fig. 170 ): L/W: 2.47, pterostigma: lp/wp: 3.83; areola postica high, la/ha: 1.62. Hindwings ( Fig. 171 ): l/w: 2.82. Subgenital plate ( Fig. 174 ) triangular, with dense field of long setae, apex rounded. Gonapophyses ( Fig. 175 ): v1 elongate, slender, acuminate, about two thirds the length of v2 +3; this wider in the middle, with a proximal, pointed heel, v2 +3 wide basally, a row of 8 medium sized setae, including two macrosetae on v2. Distal process long, sinuous and acuminate, with microsetae. Ninth sternum concave anteriorly, projected posteriorly, with membranous areas on sides ( Fig. 175 ). Paraprocts wide based, triangular ( Fig. 173 ), with setae as illustrated; sensory fields with 22 trichobothria on basal rosettes. Epiproct triangular ( Fig. 173 ), setae as illustrated.
