Poecilosomella View in CoL picturata ( MALLOCH, 1913)

( Figs 69–72 View Figs 69–72 )

Limosina picturatus View in CoL : MALLOCH 1913: 653 (cf. ROHÁČEK et al. 2001: 201).

Holotype male ( NMNH): 1) Manila PI – 2) RobtBrown Collector – 3) Type No. 15308 U.S. N.M. – 4) “ Limosina picturatus MALLOCH Type” [pencil handwriting]; glued to the tip of a small long narrow card, right wing much damaged; abdomen with genitalia in a plastic microvial with glycerine.

Body features, other than mentioned below, are the same as in P. borboroides (WALKER) and in P. ornata (DE MEIJERE) .

Apical part of vein R 2+3 rather edged at curvature, distally to this point a distinct brown spot present, similarly as in P. formosana sp. n. Mid tibia with ventral medial seta at 3/5.

Male abdominal sternite 5 ( Fig. 72 View Figs 69–72 ) asymmetrical, median hairs located on a broad medial section, similarly as in P. ornata . Subepandrial sclerite ( Fig. 69 View Figs 69–72 ) unique, with comparatively broad and bare medial process and with straight and edged ventral (lateral) pair of processes, broader than in P. ornata ; lateral processes bear thicker setae, contrary to P. ornata and similarly to P. formosana . Ap ical part of surstylus ( Fig. 70 View Figs 69–72 ) caudally with a single thick black tooth, whose size and position are different from those of P. ornata , i.e. without a process caudally to the tooth. Postgonite ( Fig. 71 View Figs 69–72 ) not very broad, not strongly narrowing apically, apical part curved apically but less strongly, apex with a small blunt projection (rather than a tooth as in P. ornata ).

This species is distinguishable from P. borboroides by the distinct brown spot on its wings just distal to the curvature of R 2+3. Of course, the safe distinction is based on the characteristics of the male postabdomen and genitalia.
