Lepidostoma diespiter (Malicky & Sangpradub, 2001)

Dinarthrum diespiter Malicky & Sangpradub, 2001; 13, figs.

Description.

Adult ♂ (Fig. 1D View Figure 1 , 1E View Figure 1 ): Scapes each with single basal process, broad basally and apically tapering to forms finger-like structure. Maxillary palps each single-segmented, medially with long projection apically somewhat tapering, covered with dense setae (Fig. 1D View Figure 1 ). Forewings each with apical forks I and II and with three post-cubital cells (Fig. 1E View Figure 1 ).

Genitalia ♂ (Fig. 1A-C, F View Figure 1 ): Segment IX posterodorsally produced into triangle with round apex, segment IX dorsolateral projections rounded. Segment X in dorsal view (Fig. 1A View Figure 1 ) anterodorsally wide, constricted at mid-length then tapering towards apex, apex with small notch equipped with triangular projection; in lateral view (Fig. 1C View Figure 1 ), posterolaterally divided into two apically round lobes, dorsal lobe projected posterodorsad and pair of ventrolateral lobes projected posteroventrad, small acute triangular projection visible below ventrolateral lobes of tergum X. Inferior appendages each single-segmented, in lateral view (Fig. 1C View Figure 1 ) basal 2/3 tubular, distal 1/3 with two processes: apicodorsal process half as thick as basal 2/3 and apically truncate, apicoventral process digitate; in ventral view (Fig. 1B View Figure 1 ) each inferior appendage curved caudad, apically bilobed with clavate apicodorsal lobe twice as long as clavate apicoventral lobe. Phallus tongue-shaped in ventral view (Fig. 1B View Figure 1 ) and in lateral view (Fig. 1F View Figure 1 ) phallus apically rounded triangular with parameres placed diagonally across genitalia); basodorsal process present, serrated, and finger-like.

Note.

According to Malicky et al. (2000), D. diespiter shows similarities to D. palmipes Ito, 1986 in the morphology of segment X, although the middle cone of segment X (actually the apex of tergum IX) is significantly shorter in D. palmipes . Moreover, D. palmipes possesses bifurcate parameres. D. daidalion Malicky & Prommi, 2000 is even more similar, but it also exhibits a considerably shorter dorsal cone of tergum IX.
