Alaptus minutus Dozier, 1932

( Figs 185–189 )

Alaptus minutus Dozier 1932: 89 –90. Type locality: Port-au-Prince , Haiti.

Alaptus minutus Dozier : De Santis 1979: 362 (catalog); Yoshimoto 1990: 23 (list).

Type material examined. Holotype male [USNM] on slide ( Fig. 187 ) labeled: 1. “ Alaptus minutus Dozier ♂ Reared from lime foliage infested with Parlatoria zizyphus etc. Port-au-Prince, Haiti. June 18, 1931 H. L. Dozier”; 2. [red] “ Alaptus minutus Dozier ♂ Type No. 69494 U.S.N.M.”; 3. [barcode] “USNMENT 01049024”. The holotype ( Fig. 185 ) is uncleared, complete, mounted dorsoventrally.

Distribution. Neotropical:? Argentina * and Haiti.

Hosts. Unknown.

Comments. The body length of the holotype ( Fig. 185 ) is 291 µm, not 215 µm as it was incorrectly indicated by Dozier (1932). Its other important features are as follows: antenna ( Fig. 188 ) with F1 much shorter than pedicel and a little shorter than the following flagellomeres; midlobe of mesoscutum faintly transversely striate, without adnotaular setae; axillar seta ( Fig. 186 ) extremely long (90 µm), extending beyond posterior margin of propodeum; fore wing ( Figs 185, 189 ) 9.6× as long as wide, disc with a median row of 7 setae on one wing and 10 setae on the other wing, longest marginal seta 4.6× maximum wing width, the macrochaeta on the marginal vein very long (90 µm). This Neotropical species is without any doubt a good taxon but a conspecific female from Haiti is needed to provide its proper diagnosis. However, I have identified the following two rather poorly slide-mounted females as very likely to be A. minutus : ARGENTINA: MISIONES : Loreto, 14.ii. 1 949, [A.A. Ogloblin] [1 ♀, MLPA] . San Ignacio, Chacra Yabebirí, 3.iv.1931, A.A. Ogloblin [1 ♀, MLPA]. They are characterized by the following morphological features: body length 240 µm and 270 µm; antenna shorter than body, with rather short funicle segments (all at least a little longer than wide, F1 the shortest and F2 shorter than following funicle segments), mesosoma notably lighter than head and gaster; fore wing about 10× as long as wide, disc with a median row of about 11 setae, and macrochaeta on marginal vein very long.
