Manota hidalgoensis sp. n.

Figs 2 A–D

Male. Colour. Head pale brown, frons, vertex and dorsal part of occiput darker brown, ventral part of two basal flagellomeres paler than rest of antenna, mouthparts paler than face. Thorax brown, preepisternum 2 paler than the other parts. Legs unicolorous pale yellowish. Wing unicolorous yellowish-brown; haltere yellowish-brown with dark brown knob. Abdominal tergites brown, sternites very pale, almost colourless. All the setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 2 A. Palpomere 3 of maxillary palpus with apicomesial extension, with three apically expanded curved sensilla; palpomere 4 with parasegment; palpomere 5 1.3 times as long as palpomere 4. Number of large postocular setae 8–9. Thorax. Anepisternum setose, with 37–42 setae, anterior basalare non-setose, preepisternum 2 non-setose, laterotergite non-setose, episternum 3 setose, with 8–11 setae. Wing. Similar to Fig. 1 B, length 1.9 mm. Hypopygium, Figs 2 B, C, D: Sternite 9 with the lateral margin fused with gonocoxa, with a deep medial furrow, posteriorly extending to the middle between anterior margin of gonocoxa and base of gonostyli, anterior margin deeply incised, the setae similar to the adjacent ventral setae of gonocoxa. Ventral mesial margins of gonocoxa slightly concave, close to one another. Posteroventral margin of gonocoxa transverse at middle and then curving posteriad to form the mesial margin of large posterolateral lobe. Ventral setosity of gonocoxa unmodified. No parastylar lobe observable. No paraapodemal lobe observable. Dorsal mesial margin of gonocoxa simple, convex. At dorsal medial margin, lying on a more ventral level, with two lobes, a more anterior finger-like lobe bearing a long sharp megaseta and a more posterior low lobe bearing 7–8 blunt megasetae. In addition, with a membraneous pointed lobe between the latter and the juxtagonostylar megasetae. Setae on the dorsal side of gonocoxa unmodified except for a large transverse megaseta at base of the large posterolateral lobe. Two juxtagonostylar megasetae present, the more ventral one flattened and flame-shaped, the more dorsal one rod-like with a short fine apex, both megasetae arising from a common basal body which is nearly as long as the megasetae. Gonostylus short, broadening from narrow base to broad and transverse apex, non-setose except for apical margin where there are two long setae at apicomesial angle, three strong curved setae at middle of margin and a group of fine setae at apicolateral angle. Aedeagus elongate-subtriangular, without distinct lateral shoulders, without Discussion. M. hidalgoensis is similar to M. arenalensis Jaschhof & Hippa , known from Costa Rica. The two species are distinguished by the shape and chaetotaxy of the gonostylus. In M. hidalgoensis the gonostylus widens from base to a very broad transverse apex, whilst in M. arenalensis the gonostylus is narrow throughout the whole length; in M. hidalgoensis there are two fine setae at the apicomesial angle, whilst in M.

arenalensis there is one fine and one conspicuously thicker seta; and in M. hidalgoensis , there are three very strong curved setae at the apical margin between the apicomesial and apicolateral corners, whilst in M. arenalensis the setae are absent. Furthermore, the two species differ by the dorsomesial chaetotaxy of the gonocoxa. In M. hidalgoensis there are 5–6 megasetae on the lobe between the large anterior-most megaseta and the juxtagonostylar megasetae, whilst in M. arenalensis there are only three; and in M. hidalgoensis the more dorsal of the juxtagonostylar megasetae is rod-like, whilst in M. arenalensis it is flat and slightly bilobed. M. arenalensis differs from the three other Mexican species dealt with in this paper by having a nonsetose laterotergite.

Etymology. The name is a Latinised derivation from the Mexican state of Hidalgo where the type locality is situated.
