Allophrys miklouhomaclayi Khalaim et Villemant, 2019

Figs 1–6 .

MATERIAL EXAMINED. Indonesia, South Sulawesi, Gowa Prov. [Regency], “Mt. (Gunung) Lompobattang”, 5°23´26´´S, 119°56´01´´E, 2000 m, “5 Malaise traps ”, 16.I–27.II.2012, coll. K. Takasuka, 4 ♀♀, 1 ♂ (3 ♀♀, 1 ♂ in EUM; 1 ♀ in ZISP) .

COMPARISON. Allophrys miklouhomaclayi is similar to A. davichia Khalaim, 2018 as both have a slender mandible with the upper tooth about 2.5 times longer than the lower tooth ( Fig. 5 ), slender antennal flagellum ( Fig. 6 ), strong foveate groove on the mesopleuron ( Fig. 6 ), and antefurcal second recurrent vein (2 m-cu) in the fore wing, but distinct in having a longer gena ( Fig. 3 ), occipital carina dorsally complete, narrower foveate groove of the mesopleuron, and long and narrow basal area of the propodeum.

DESCRIPTION. ♂ (first record). Eyes not enlarged ( Figs 2–4 ). Clypeal pits large and deep ( Fig. 4 ). Vertex mediodorsally impressed ( Fig. 3 ). Malar space almost 1.3 times as long as basal mandibular width (longer than in ♀). Metasoma brown ( Fig. 2 ). Otherwise as in ♀.

REMARKS. Unlike known ♂♂ of other Allophrys species, which have characteristically distinctly enlarged compound eyes (always much larger than the eyes of ♀♀), and thus with considerable sexual dimorphism in the genus, A. miklouhomaclayi possesses unspecialized (i.e. not enlarged) eyes of the ♂. This fact is evidence that this important generic feature of Allophrys (enlarged eyes of ♂♂) does not work well in all species, and therefore must be used with caution in generic and species diagnoses. Nevertheless, species of Allophrys can be distinguished from those of the close genus Phradis Förster, 1869 by the presence of hypostomal carina and usually strongly reclivous nervellus in the hind wing.

VARIATION. One pale ♀ is almost entirely brownish orange.

DISTRIBUTION. Papua New Guinea, Indonesia. First record from Indonesia.
