Treatment

Ceratitis (Ceratalaspis) ealensis View in CoL sp. n.

( Figures 4 View Figures 1–5 , 10 View Figures 7–11 , 16 View Figures 12–17 )

Diagnosis

Arista with short rays; frons yellow, without silvery microtrichosity; postpronotal lobe without a spot; scutal pattern with distinct black markings but spots restricted; anepisternum yellow, with two anepisternal setae; wing bands with subapical band joined to discal band, posterior apical band absent; legs without feathering; abdomen without distinct spots, with grey band on tergites 2 and 4; apical part of aculeus with two large rounded indentations.

Description

Female. Head: antenna yellow. First flagellomere two times as long as pedicel. Arista with short rays, longest dorsal rays usually about as long as basal width of arista; if somewhat longer never twice as long as basal width. Frons yellow; with short scattered yellow setulae. Face yellowish white, below lower eye margin darker yellow. Genal setulae and genal seta yellow to orange, well developed.

Thorax: postpronotal lobe yellow; without spot. Scutal pattern ( Figure 4 View Figures 1–5 ), ground colour yellow, with distinct black markings but the latter strongly reduced; prescutellar markings white, separate or merged; with yellow microtrichosity and pilosity. Scapular setae yelloworange. Scutellum yellow-white, basally without black spots, apically with three separate black spots, extending to basal half. Subscutellum yellow with three separate black spots. Anepisternum yellow; setulae yellow; two black anepisternal setae, occasionally with a third, less developed and dark orange, seta below two black ones.

Legs: yellow; setation yellow to orange. Fore femur with ventral setae orange.

Wing: pattern as in Figure 10 View Figures 7–11 ; bands mainly yellowish with some brown patches. Anterior apical and discal bands not separate; subapical band joined to discal band; posterior apical band absent; crossvein R-M at basal third of discal medial cell.

Abdomen: yellow; pilosity mainly yellow. Tergites 2 and 4 with pale grey band occupying posterior third to half of tergite. Tergite 5 with longer black setulae along posterior margin. Oviscape about as long as preabdomen. Aculeus eight times longer than wide, apical part ( Figure 16 View Figures 12–17 ) with two large rounded indentations, tip with small depression.

Male. As female.

Body length. 5.98 (5.15–6.55) mm.

Wing length. 5.75 (5.50–5.95) mm.

Type material

Holotype: ♀, Democratic Republic of Congo, Eala , 26 January 1935, leg. J. Ghesquière, sample 170, ‘‘larves dans fruits d’ Anopyxis ’’ . Holotype deposited in collection of KBIN . Paratypes: 4 „„, 1♀, Democratic Republic of Congo, Eala , 26 January 1935, leg. J. Ghesquière, sample 170 . Paratypes deposited in the collections of KBIN and KMMA .

Etymology

Named after the type locality, Eala.

Host plant

Reared from the fruits of Anopyxis (Pierre) Engl. sp. (Rhizophoraceae) .

Remarks

C. ealensis View in CoL keys out to C. hancocki De Meyer in De Meyer (1998) View in CoL . It shows some affinities with this species, but lacks a black spot on the postpronotal lobe, has lateral presutural black spots that do not reach the postpronotal lobe, and possesses an aculeus that lacks the large blade-like serrations. It seems to be more closely related to C. paradumeti De Meyer. The View in CoL latter has a similar strongly reduced mesonotal pattern with restricted black spots, and an aculeus with rounded indentations. C. ealensis View in CoL can be differentiated by the depression at the tip of the aculeus (rounded and without depression in C. paradumeti View in CoL ), and by the subapical band joining the discal band (subapical band isolated in C. paradumeti View in CoL ). More material of both species is, however, needed to unambiguously confirm the status of both taxa. This species can be identified with the key provided by De Meyer (1998) given the following adjustment.
