Manota tricuspis

sp. n.

Manota tricuspis  sp. n.

( Figs 14View FIGURE 14 A –C)

A small-sized Manota  .

Male. Coloration. Almost unicolorous pale yellowish-brown. Head. Antennal flagellomere 4, Fig. 14View FIGURE 14 C. Palpomere 3 of maxillary palpus with apicomesial extension, with 5 apically expanded curved sensilla; palpomere 4 with parasegment. Thorax. Pleural setosity pattern similar to M. bicuspis  , Fig. 1View FIGURE 1 E: anepisternum setose, with 52 setae; anterior basalare non-setose; preepisternum 2 setose, with 19 setae; laterotergite setose, with ca. 28 setae; episternum 3 setose, with ca. 10 setae. Wing. Length 1.6 mm. Hypopygium ( Figs 14View FIGURE 14 A, B). Sternite 9 extending halfway between the base of gonocoxa and the base of gonostylus, laterally sharply delimited, posterior margin slightly notched, anterior margin deeply incised, setae similar to ventral setae of gonocoxa. Parastylar lobe well exposed, flat, with 2 posteriorly directed setae. Paraapodemal lobe exposed in ventral view of hypopygium. The dorsal mesial margin of gonocoxa simple except for a large setose lobe apically. Two juxtagonostylar setae present, a long slightly curved megaseta and a slightly shorter seta, arising from a basal body, which is about one-fourth of the length of the megaseta. Gonostylus elongate, simple, with long setae, apically with three strong setae, which are nearly as long as the gonostylus. Tegmen narrowly triangular, with weakly expressed shoulders. Hypoproct posteriorly extending to the level of the middle of gonocoxa, with ca. 7 setae on each side, mostly placed at the lateral margin. Cerci separate.

Female and preimaginal stages unknown.

Discussion. M. tricuspis  resembles M. gemella  but differs in its quite different gonostylus, which is twice as long, has three huge apical setae and lacks a small setose lobe at the middle of the mesial margin. Furthermore, the setose lobe apicodorsally on the gonocoxa is more mesial in position and has at its mesial margin two transversely directed setae, which diverge from the other setosity.
