Diagnosis.

Belonging to the new species group Yalcona . Forewings with a slender, pigmented marginal band, from R4+5 to areola postica (Fig. 43). Pterostigma elongate, not angulated towards Rs. Hypandrium of three sclerites, central one anteriorly straight, with two lateral, long, slender acuminate posterior processes, and two median, shorter, acuminate posterior processes (Fig. 46). Phallosome built on the same plan as in species group Guentherbuchi , but differing in details of the endophallic sclerites.

Description.

Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Antennae pale brown, flagellomeres with apices cream. Maxillary palps pale brown, Mx4 dark brown apically. Tergal lobes of meso- and metathorax dark brown. Thoracic mesopleura brown, more pigmented than pro- and metapleura. Legs: fore- and hind- coxae creamy, with small proximal and distal brown spots; mid coxae brown, trochanters and femora pale brown, tibia and tarsi brown. Wings almost hyaline, forewings as diagnosed above (Figs 43 and 44). Abdomen creamy, with subcuticular transverse ochre bands. Clunium and hypandrium brown. Epiproct and paraprocts pale brown, phallosome pale brown, with endophallic sclerites more pigmented.

Paraprocts (Fig. 48) robust, elongate, setose as illustrated, sensory fields with 32 trichobothria on basal rosettes. Epiproct wide, semioval, posteriorly rounded, convex anteriorly, with macrosetae on each basal angle, posterior border with setae as illustrated (Fig. 48).
