Lotobia latipes View in CoL sp. n.

( Figs 11–22 View Figs 11–14 View Figs 15–18 View Figs 19–22 )

Description – Body length 2.7–3.1 mm (holotype male 3.0 mm).

Head: Mostly dark reddish brown; gena mostly bright reddish brown, shining, subgena darkened; frontal vitta entirely granulated; inner and outer vt, oc, and 2 ors almost same length; postocular setae weak and few; lunule, epistoma and clypeus entirely yellowish brown, clypeus small, about twice as wide as long; eye round, about 1.5 times as long as smallest genal width; antenna yellowish brown; scape with 2 long hair-like setae; pedicel with 2 long blunt setae and several short setae.

Thorax: Postpronotal lobe and scutum entirely black; ac setae very short and dense, completely diffused with dc setae; only posterior np distinct; anepisternum dark brown; katepisternum reddish brown to dark brown, 2–5 setae along central vertical axis and 2–3 long hairs ventrally; scutellum with 18 marginal tubercles, concolorous to scutellum, basal 2 fused at the base.

Wing: Slightly brownish, veins brown; R 4+5 only slightly bent forward; M 1+2 strongly bent forward and distinctly convergent to R 4+5; halter pale brown to yellow.

Legs: Coxae, femora, tibiae and basal 2 tarsomeres yellow to yellowish brown, 3–5 tarsomeres somewhat darkened; male fore and hind femora somewhat thickened; fore and hind tarsomeres much dilated; hind tibia with 2 strong ventral spines apically.

Abdomen: Preabdominal tergites strongly sclerotized dark brown, tergites 1+2, 3 and 4 in both sexes with large central microsetose areas ( Figs 11, 13 View Figs 11–14 ).

Male. Black, syntergite 1+2 about 1.5 X as long as tergite 3, tergite 3 a little shorter than tergite 4, tergite 4 twice as long as tergite 5, male tergite 5 ( Fig. 11 View Figs 11–14 ) slightly asymmetrical, about 2 times as broad as long, and only slightly longer than half length of T4, wholly covered by microsetae. Male sternite 2 (setae sparse, only on caudal part) and 3 (setae comparatively long but much less dense than on S4) normal in size, both somewhat broader than sternite 4, but much less sclerotized (melanized) than sternite 4. Male sternite 4 ( Fig. 12 View Figs 11–14 ) much longer than broad, with latero-caudal prolongations, and wholly covered by setae; sternite 5 very narrow.

Male cerci ( Fig. 15 View Figs 15–18 ) rather large with long setae, particularly medially and apically, crescent-shaped in caudal view. Surstylus ( Figs 17–18 View Figs 15–18 )) rather long with rounded apex, medial surface with short and medium-long thick black setae ( Figs 15, 17 View Figs 15–18 ), lateral (outer) surface with numerous long setae. Paramere (postgonite) ( Fig. 20 View Figs 19–22 ) characteristic with its large sub-basal seta and with its strong subapical process. Distiphallus ( Fig. 16 View Figs 15–18 ) robust, medium long and rather thick.

Female. Black, syntergite 1+2 about 1.5 times as long as tergite 3, tergite 3–5 almost same length; tergite 5 ( Figs 13–14 View Figs 11–14 ) slightly broader than long, with rows of caudal setae but without microsetae. Female sternites 2 and 3 ( Fig. 19 View Figs 19–22 ) rather large but weakly sclerotized, sternite 2 with a small anterior patch of microtrichia, sternite 4 ( Fig. 21 View Figs 19–22 ) rather large with a more melanized central part. Sternites 2–5 with a pair of long setae on posterior margin; sternite 5 not divided. Sternites 3 and 4 without microtrichia, sternite 5 ( Fig. 21 View Figs 19–22 ) with a large central microtrichose spot.

Female hypoproct ( Fig. 22 View Figs 19–22 ) twice as long as than epiproct, cerci normal. Spermathecae globular.

Holotype male ( NIID): Nagarahole National Park , 720 m, Karnataka Sta., India, Oct. 9–10, 1993, T. Hayashi.

Paratypes. INDIA: 5 males, 1 female, same data as holotype (a pair in HNHM) ; 2 females, Gudalur , 1,200–1,500 m, Tamil Nadu Sta., Oct. 6–9, 1993, T. Hayashi . THAILAND: 4 females, Khaophappha Khaochang , 200–400 m, Trang Prov., Jan. 4, 1964, G. A. Samuelson ( BPBM) .

Distribution. India and Thailand. for Figs 11 and 12 View Figs 11–14 , respectively, 0.5 mm for Figs 13–14 View Figs 11–14 lateral (outer) view. Scales: 0.2 mm for Fig. 15 View Figs 15–18 , 0.1 mm for Figs 16–18 View Figs 15–18

Remarks. This species is very characteristic among the Oriental species, having much dilated tarsomeres and 2 developed spines on hind tibia apically.

The specimens from India were collected on wild elephant and gaur dung.
