Formosargus mangoleensis View in CoL sp. nov.
( Figures 4 View Figure 4 (c), 6(c), 7(g), 16(a), 17(i–j), 19(f), 20(a))
Diagnosis (female)
Medial band on scutum narrow, not reaching the extreme anterior end of scutum ( Figure 7 View Figure 7 (g)), wider posteriorly. Vertex at least twice the length of the ocellar tubercle ( Figure 4 View Figure 4 (c)); upper frons shortened, nearly three times shorter than lower frons ( Figure 6 View Figure 6 (c)). Mediotergite completely yellow; anepisternum with a small subrectangular dark spot ( Figure 20 View Figure 20 (a)). Abdomen entirely pale yellow.
Material examined
HOLOTYPE, 1 ♀ (genitalia dissected and stored in microvial with glycerine), INDONESIA, [North Maluku Province], Sula Isl. [ Island] Mangole , 2 km W. Mandafuhi Camp, Mal. [ Malaise ] trap 19, c 70 m, 07–24 March 1995, C.v. Achterberg and Y. Yasir ( RMNH) . PARATYPE, 1 ♀, INDONESIA, [North Maluku Province], Mangole, Mandafuhi Camp , 05 March 1995, along road, C.v. Achterberg, RMNH 95’ ( RMNH) .
Description
Female. Length (n = 2): body, 10.0 mm; wing, 9.0 mm. Head ( Figures 4 View Figure 4 (c), 6(c)). Vertex area twice longer than ocellar tubercle. Upper frons shortened, twice wider than long, nearly three times shorter lower frons; upper frons black lateral area nearly as broad as ocellar tubercle width, with short brownish pilosity; anterior margin nearly straight at the edge with lower frons, only medially pointing towards antennal insertion. Fourth flagellomere rounded, as wide as each previous flagellomere alone or slightly wider. Face three times shorter than lower frons. Thorax ( Figure 7 View Figure 7 (g)). Medial dark brown band covering less than one-third of scutum width, not reaching extreme anterior end of scutum, wider on posterior half and scutellum; pleuron pale yellow, with only a small subrectangular dark brown spot on anepisternum. Wing. R2+3 originating slightly before r–m, weakly curved on basal third, straight on apical two-thirds. Abdomen. Completely yellow; pilosity yellow. Terminalia ( Figures 16 View Figure 16 (a), 17(i, j)). Genital fork wider at posterior half at level of posterior bridge; anterior half gradually narrowing into a long and curved anterior end; posterior bridge bilobed; posterolateral process parallel, slightly wider at base, gradually narrowing towards a rounded apex; genital opening roughly circular.
Male
Unknown.
Etymology
The specific epithet, mangoleensis , refers to the collection site of the holotype of the new species, the island of Mangole , in the Sula Islands, Indonesia.
Geographic distribution
Oriental Region. Indonesia (North Maluku: Mangole Island) ( Figure 26 View Figure 26 ).
Comments
This species, as mentioned, shares with the females of F. kerteszi a small dark spot on the anepisternum and mediotergite completely yellow. However, it is distinguished from F. kerteszi by a vertex area twice the length of the ocellar tubercle ( Figure 6 View Figure 6 (c)); also, in F. mangoleensis sp. nov., the upper frons is relatively shorter than that in F. kerteszi (see Figures 5 View Figure 5 (b, c) and 6(c) for comparison) and it has a medial band slightly wider, that does not reach the extreme apex of the anterior part of scutum (see Figures 7 View Figure 7 (b) and 7(g) for comparison). Besides these features, F. mangoleensis sp. nov. is so far the only species reported within the limits of Wallacea ( Figure 26 View Figure 26 ) – the area between Wallace’s Line and Lydekker’s Line – while F. kerteszi is found more to the north, beyond Wallace’s Line. The nearest species in geographical proximity to F. mangolensis sp. nov. is a record of F. lineatus from the Island of Waigeo, Indonesia, near the north-west boundary of Lydekker’s Line, which is in the Australian Region.
