Culoptila buenoi , new species

Fig. 17 A, B

This species is closely related to Culoptila kimminsi and together they form a distinctive species pair. They are similar in the general shape of the phallobase and its posterodorsal apex, and in the possession of a curved phallic spine with numerous smaller accessory spines. This curved phallic spine is apparently united basally with a 2nd, elongate spine, which is nearly straight and lacks accessory spines. A distinctive and diagnostic difference between C. buenoi and C. kimminsi is the shape of the inferior appendages. In both species they are relatively elongate and curved, but they are much more prominent and apically widened in C. buenoi .

Adult. Length of forewing: male 3 mm. Color brown in alcohol. Mesothorax of male narrow anteromesally; mesoscutal wart elongate, narrowed, rounded anteromesally; mesoscutal setae long. Mesothoracic tegulae of male rounded, distinctly enlarged; tegular setae long; tegular gland present, length not ascertained because gland not everted.

Male genitalia. Sternum VI process short, subtruncate. Tergum IX ventral margin acutely angled, tapered from anterolateral margin, not produced posteroventrally. Inferior appendages very long, wide apically, divergent basally, sharply curving mesad apically. Tergum X short, about as long as wide, apex in ventral view broadly rounded to subtruncate; ventrolateral processes with apices incurved, nearly planar in caudal view, mesal margin nearly orthogonal; apices not or scarcely posteriorly bent. Phallobase moderate in size, rounded, anterior end narrowed, apicodorsal projection weakly arched, apicodorsal projection moderately elongate, apex subacute. Phallic apparatus with 2 phallic spines, phallic spines united basally, shorter spine much thickened, sinuously twisted around longer spine, with numerous, overlapping accessory spines, longer spine about 3/4 length of phallobase, weakly curved, apically narrowed, acuminate.

Material examined

Holotype male: MEXICO: Puebla: 26 km N Xicotepec de Juárez, km 93, Rta 130, 23.i.1985 (Bueno­Soria) ( UMSP 000092422) ( UNAM).

Additional material examined: same data as holotype, 1 larva, 1 pupa (without abdomen), 2 male pupae, 1 female pupa ( UNAM).

Etymology

We take great pleasure in naming this species for Dr. Joaquin Bueno­Soria, in honor of his many contributions to the taxonomy and systematics of Neotropical caddisflies.
