Material examined

THAILAND: Ƌ, Royal Agricultural Station Angkhang, Fang, Chiang Mai, 19°54’05”N, 99° 2’25”E, ca 1420 m a.s.l., 12 August 2014, leg. N. Likhitrakarn ( CUMZ).

Descriptive notes

MEASUREMENTS AND COLOUR. Length 43.8 mm, width of midbody pro- and metazonae 3.51 and 5.04 mm, respectively. Coloration of live animal, as well as of alcohol material black-brown ( Fig. 23 View Fig A–G), head and venter dark to light brown, legs and antennae yellowish brown to light yellowish.

BODY. Antennae rather short ( Fig. 23B View Fig ), extending behind body segment 3 (Ƌ) when stretched dorsally. In width, segment 3 <4 <5 <collum <segment 2 <6–17; thereafter body gently and gradually tapering. Collum with three transverse rows of setae: 4+4 anterior, 1+1 intermediate and 4+4 posterior; a very faint incision laterally in posterior 1/3; caudal corner of paraterga very broadly rounded, not drawn behind rear tergal margin ( Fig. 23B – C View Fig ). Paraterga 2 well-developed ( Fig. 23B – C View Fig ), horizontal, lateral edge with two minute incisions in anterior half, caudal corner very narrowly rounded. Paraterga 3 and 4 each nearly pointed, expanded laterally, with two minute incisions in the middle. Sterna densely setose and finely microtuberculate ( Fig. 24D View Fig ); with a large, subtrapeziform, ventrally slightly concave, sternal lobe between Ƌ coxae 4 ( Fig. 23I – J View Fig ). Legs rather long and slender, midbody ones ca 1.2–1.3 (Ƌ) as long as body height; Ƌ legs without tarsal brushes; Ƌ postfemora and tibiae each with an adenostyle (tubercle) on segments 8–17; Ƌ coxae, prefemora, femora and postfemora microtuberculate ventrally ( Fig. 24C – D View Fig ).

Remarks

This new specimen agrees in most details with the original description ( Golovatch & Enghoff 1993), especially in gonopod structure which shows a huge spine z serrate on both sides ( Figs 24A – B View Fig , 3 View Fig ), and in a large body. Thus, to document its identity the new specimen has been illustrated in detail for comparative purposes ( Figs 23–25 View Fig View Fig View Fig ). The type locality of T. baenzigeri, Doi Suthep National Park, is located quite far away (about 120 km) from this new place.
