Male ( Figs 16–20 ) Diagnosis. Differing from P. casasolai n. sp. , in having the phallosome with one body of endophallic denticles and in having the external parameres shorter, broader, with spiny apices shorter, curved outwards ( Fig. 19 ). Arms of the aedeagal arch shorter than in P. casasolai ( Fig. 19 ); posterior border of the hypandrium similarly biconcave, but the postero-lateral corners are distinctly rounded ( Fig. 20 ). Clunial projection over the area of the epiproct wider and deeper than in P. casasolai ; projections over the area of the paraprocts larger than in P. casasolai ( Fig. 18 ). Differing from all the other species of Prolachesilla in the arrangement of the endophallic denticles and in the shape of the posterior border of the hypandrium. Color . Body tawny brown, compound eyes black, legs pale brown, forewings pale yellow, hindwings hyaline, almost transparent ( Fig. 16 ). Tergal lobes of meso- and metathorax pale brown, abdomen creamy with pale brown subcuticular, transverse bands. Morphology. As in diagnosis plus the following: Head vertex almost straight, slightly below the level of the upper borders of the compound eyes, these large, prominent ( Fig. 17 ). Forewing L/W: 2.53 ( Fig. 16 ). Forewing pterostigma elongate, wider distally, lp/wp: 3.09, without setae in the membrane. Areola postica triangular ( Fig. 16 ). Hindwing L/W: 2.89 ( Fig. 16 ). Hypandrium ( Fig. 20 ) and phallosome ( Fig. 19 ) as in diagnosis ( Fig. 19 ). Paraprocts ( Fig. 18 ), oval; sensory fields with 15 trichobothria on basal rosettes. Epiproct ( Fig. 18 ), almost trapeziform, slightly rounded posteriorly, setae as illustrated. Measurements (in microns).
