Purenleon farri Miller and Stange , new species

Figures 84–87

Holotype female, Stewart Town , Jamaica ( FSCA).

Diagnosis. Pronotum without elongate white bristles at lateral margin; forecoxa without long white bristles; hind basitarsus longer than tarsomeres II–IV together; forewing vein CuP+1A reaches hind margin well beyond origin of raial sector; female terminal with posterior gonapophysis close together at base (separated by about 3.5 gonaphysis base diameters), about five times longer than median diameter; lateral gonapophyses fused together at middle.

Holotype female. Length of body 34 mm; forewing 40 mm; hindwing 39 mm. Coloration: antennal flagellomeres mostly pale brown except narrow dark brown ring at base, scape all dark posteriorly except apex; pronotum with broad dark brown submedial band, dark brown laterally; pterothoracic nota nearly all dark brown with limited light brown areas; forefemur nearly all dark brown; hindtibia mostly pale brown except apically; tarsi with basitarsus mostly pale brown, tarsomeres II–IV mostly dark brown, distal tarsomere mostly pale brown except apically; abdomen nearly entirely dark brown. Chaetotaxy: pronotum without elongate white bristles at lateral margin, sometimes shorter, often black bristles present which are much shorter than those on forecoxa; thoracic pleura with many elongate white setae ventrally; forefemur with many white, decumbent setae; forecoxa without long white bristles; abdominal sternite II with elongate white setae in contrast to sternites III–VII; midfemoral sense hair about one-half as long as forefemoral sense hair; sternite VIII of female with long setae submedially at posterior margin. Structure: pronotum a little broader than long measured along midline; hind basitarsus somewhat longer than tarsomeres II–IV together; forewing longer than hindwing; forewing costal area abruptly broadened at base, crossveins more than twice as high as wide at middle, not interconnected; forewing vein CuP+1A reaches hind margin well beyond origin of radial sector; female terminalia ( Fig. 87 ) with ectoproct with short postventral lobe with many stout digging setae; posterior gonapophysis close together at base (separated by about 3.5 gonapophysis base diameter), about five times longer than median diameter with long setae toward apex nearly as long as gonapophysis; gonapophyseal plate about four times longer than wide; lateral gonapophyses fused at middle, about three times as long as broad with many short digging setae; pregenitale a transverse sclerite much broader at middle where elongate posterior process exists which is about four times longer than median diameter, narrows apically.

Material studied. Only the holotype female. JAMAICA. Trelawny: Stewart Town (1f, FSCA).

Discussion. The female terminalia differ from other species by having the posterior gonapophyses very close together at base (similar only to P. reductus ), lateral gonapophyses fused at middle and in the shape of the pregenitale which has a long posterior process (about four times longer than median diameter).

Etymology. This species is dedicated to Thomas Farr who contributed greatly to our knowledge of Jamaican insects.
