Diagnosis.
Eyes 3+3 eyes. Post antennal organ in rosette with 5 or 6 vesicles. Ant IV with six sensilla. Seta a0 on head absent. Mandible with four teeth. Dens with three setae. Unguis without internal tooth.
Description.
Average body length: adults 1009 µm (n = 5); juveniles 847 µm (n = 2). Specimens in ethanol with antenna and abdomen evenly grey, ocular patch dark; head, legs III, and furcula light grey; thorax, legs I and II white to light purple (Fig. 1 View Figure 1 ). Granulation coarse. Body setae comprising short, smooth and thin setae, and long and smooth sensorial setae.
Head: antenna shorter (0.6) than head diagonal. Ant III and IV fused dorsally, ventral separation clearly marked. Ant IV dorsally with trilobed apical vesicle, six subcylindrical thin sensilla and 14 long setae; subapical organite present; dorsoexternal microsensillum absent (Fig. 3 View Figures 3–8 ); no sensorial field ventrally on Ant IV (Fig. 4 View Figures 3–8 ); Ant III sense organ with two small internal slightly bent sensilla, two subcylindrical guard sensilla, Sgv larger than Sgd, ventral microsensillum present (Figs 3 View Figures 3–8 , 5 View Figures 3–8 ); Sgd apically displaced, towards Ant IV, aligned to S2 and S3; Ant II with 10 setae; Ant I with seven setae (Fig. 3 View Figures 3–8 ). Eyes 3+3 on a pigmented eyepatch; PAO with five or six vesicles disposed as a rosette (Fig. 2 View Figure 2 ). Head dorsal chaetotaxy as in Figure 2 View Figure 2 ; seta a0 absent; d row with 4 setae, sd row with three setae; setae Oc 1-3 present; c setae absent; p1-3 setae present. Buccal cone elongate, labium with complete chaetotaxy, A to G setae, C and D apically displaced (Fig. 6 View Figures 3–8 ). Pre-labral/Labral chaetotaxy 4/2322 (Fig. 7 View Figures 3–8 ). Mandible with four teeth, two apical short and subequal, one medial and one basal large and subequal; maxilla styliform with one lamella (Fig. 8 View Figures 3–8 ).
Dorsal chaetotaxy: ordinary setae smooth, distributed as in Figure 2 View Figure 2 . Th I with 2+2 setae; Th II and III with one dorsolateral seta posteriorly displaced. Sensory setae (s) clearly differentiated, in position p3 and p6 in Th II and III and in position p3 in Abd I-V; S-chaetotaxy formula = 022/11111.
Legs chaetotaxy: subcoxae 1, two; subcoxae 2, one; Cx, three; Tr, four; Fe, 10, and Ti 19 setae (Fig. 9 View Figures 9–13 ). Seta M present between B4 and B5 without displacement. Tenent hair acuminate. Claws without teeth, unguis larger than Ti (ratio tibiotarsus: unguis = 1:1.2:); unguiculus absent.
Ventral chaetotaxy as in Figure 10 View Figures 9–13 . VT with 3+3 setae; tenaculum with 3+3 teeth and without setae; furcula well developed, manubrium with 14 setae, dens with three setae, mucro straight with a broad hook-like apex (Fig. 11 View Figures 9–13 ). Ratio mucro: dens = 1: 1.3. Female genital plate with 2+2 pregenital setae, four circumgenital setae, and 1+1 eugenital setae (Fig. 12 View Figures 9–13 ). Male genital plate with 2+2 pregenital setae, ten circumgenital setae, and 4+4 eugenital setae (Fig. 13 View Figures 9–13 ).
Etymology.
Bistribus , Latin for two times three, in reference to the presence of 3+3 eyes and 3+3 setae on dens, diagnostic characters of the species.
Distribution.
This species is only the Furculanurida known from the Luquillo Mountains in the Tabebuia rigida forest type, on Pico del Este 18°16 ’17” N; 65°45 ’40” W; 987.6 m a.s.l. and Pico El Yunque 18°18 ’37” N; 65°47 ’26” W; 1044.8 m a.s.l.
Ecology.
Furculanurida bistribus sp. nov. was extracted from leaf litter and mosses in both dry and rainy seasons during November 2014, and May and August 2015.
