Paduniella monga, new species is unique in the combination of having a pair of inferior appendages being curved dorsad and truncated in lateral view; a straight median process, and a slightly sigmoid ventral part of sternite IX. The species resembles P. w a n g t a k r a i e n s i s Malicky & Chantaramongkol from Thailand in most genitalic structures. It is separated from that species in lateral view in possessing a more rectangular tergite IX, slightly longer superior appendages, wider inferior appendages, and in ventral view by the presence of a pair of rounded ventral lobes of inferior appendages.
Male genitalia. Sternite IX club-shaped in lateral view (Fig. 10); wide ventral part with convex anterior margins and shallowly concave posterior margins, nearly sigmoid in lateral view; dorsal part of sternite IX parallel-sided, straight, longer than thick ventral part, orienting anterodorsally; joining tergite IX dorsally of mid-height of genitalia. Narrow dorsal part of sternite IX forming right angle with ventral part of sternite IX. Sclerotized part of tergite IX long, narrow, rectangular in lateral view (Fig. 10), pointing posteroventrally, apex truncated. Superior appendages long, narrow in lateral view, posteriorly separate from tergite IX by suture; widening anterad; distal part with slightly convex dorsal margin; covered by setae; ventral margin straight in lateral view (Fig. 10); apex pointed. Median branch of inferior appendages visible immediately above main branch in lateral view (Fig. 10), trapezoid, covered by setae; in ventral view (Fig. 11) forming short, broad mesal lobes with slightly convex lateral margins and straight mesal margins; about half as wide as main branch of inferior appendages; originating at mid-length of main branch (Fig. 11); mesal margins nearly parallel; setae present in mesal row. Ventral lobe of inferior appendages located ventrally of main branch in lateral view (Fig. 10); in ventral view forming pair of rounded, posterad orienting lobes covered by setae (Fig. 11). Main branch of inferior appendages with parallel-sided, straight dorsal and ventral margins (Fig. 10); strongly narrowing at mid-length before widening slightly dorsally at apices; dorsoapical and posterior margins straight (Fig. 10); in ventral view, inferior appendages slightly converging, with truncate apices (Fig. 11). Phallic apparatus connecting to sternite IX and tergite IX by long, slender, nearly parallel-sided, slightly dorsad curving sternal strip (Fig. 12). Phallobase smoothly curving anterodorsally, with strongly convex ventral margin; nearly as long as sternal strip; dorsal and ventral margins parallel; anterior apex thicker than rest of sclerite. Median process long, straight, parallel-sided along its length, except narrowing posteroapically (Fig. 12). Phallicata narrowing at mid-length, slightly sigmoid, posterior apex pointing posteroventrad; apex truncated. Anterior part of paramere forming wide U with basis of phallicata; slightly curving ventrad; ventral part continuing into needle-shaped distal half slightly exceeding phallicata.
