Zaprionus Zaprionus lachaisei Yassin & David View in CoL ZBK sp. n.
Diagnosis.
This species resembles Zaprionus vittiger , but has the bigger body size (TL> 1.60 mm), spiniform spines enlarged and blackened on the first two tarsomeres of the foreleg ( Fig. 5 View Figure 5 ), and shorter puparial anterior spiracles (H = 5) ( Fig. 11 View Figure 11 ). It is also distinguishable by a peculiar behavior of the larvae which do not leave the culture bottle when disturbed or crowded.
Description.
♂. TL = 1.68 mm.
Head. Arista with 3 dorsal and 2 ventral rays plus a terminal fork, pedicel tan. Frons orange-tan with lateral white stripes; median white stripe absent; ocellar triangle raised and darker; hw:fw = 2.04, fw:fl = 1.05. Face pale; carina large; palpus yellow. Gena broad, o:j = 10.2, o:ch = 5.2. Orbital bristles in straight line; or2 very minute, or1:or2:or3 = 7:2:5, orbito-index = 1.4. Ocellar setae long, divergent; oc:or1 = 1.3, poc:oc = 0.5, iv:ov = 0.6. Eye red and densely pilose.
Thorax. Scutum tan, darker than frons, with four white longitudinal stripes continuing on scutellum; white stripes narrow, bordered with large black stripes, especially on the inner side; acs in 6 regular rows anterior to adc and 4 irregular rows between them; psc enlarged, adc:psc = 1.5; adc:pdc = 0.6. Scutellum slightly pointed at the apex, where white spot absent; bsc:asc = 1.3. Sterno-index = 0.6. F1 with 4 setiferous spines not borne on tubercules on the anteroventral margin. Basitarsus of the foreleg with a hairy brush on the ventral margin. Spiniform spines of the first and second tarsomeres of the foreleg enlaged and blackened.
Wing. Dusky; WL:WW = 2.3, C-index = 3.0, 4v-index = 1.5, 4c-index = 0.8, 5x-index = 0.7, M-index = 0.3, ac-index = 2.5, b/c = 0.6, C3 fringe 0.45, WL = 3.8 mm.
Abdomen. Uniformly tan, with dark spots at the bases of tergal bristles.
Terminalia ( Fig. 13a View Figure 13 ). Epandrium densely pubescent at ventral portion; posterior margin pubescent at dorsal portion with 5 long bristles; anterior phragma narrow; epandrial ventral lobe with 3 long bristles. Surstylus quadrate with two rows of prensisetae. Cercus triangular laterally. Hypandrium with a small pubescent patch at the lateral portion of the paraphyses. Aedeagus expanded apically; aedeagal flap expanded and deeply serrate. Apodeme subequal in length to aedeagus.
♀. TL = 1.76 mm, resembling male.
Terminalia. Oviscape with 8 peg-like and 7 short, marginal setae plus 4 supernumary. Spermatheca large, globulous and smooth ( Fig. 13b View Figure 13 ).
Egg. Elliptical with 4 equally long and fine filaments.
Larva. Not escaping the culture medium when disturbed or crowded.
Puparium. H = 5.0 ( Fig. 11d View Figure 11 ).
Distribution
. Tanzania.
Type material
. Holotype (male) and allotype (female), Tanzania: East-Usambara Mountains, Amani (870 m), ex type strain ZMI.12, 11-VIII-2008, founder female coll. 25-IX-2002, D. Lachaise. Paratypes: 10 males and 10 females with the same label. Types deposited in MNHN.
Discussion
. Attempts to hybridize this strain with others belonging to the vittiger complex have all failed. The species is very prolific and easy to breed in the laboratory.
Etymology
. Patronym, in honor of the French Drosophila systematist Dr. Daniel Lachaise (1948-2006), collector of the types of two new species described here.
