Head. Antenna shorter (ratio head: antenna: 1:0.47) than head diagonal. Ant III and IV fused dorsally, ventral separation well marked. Ant IV dorsally with eight subequal sensilla, twelve long and pointed setae, apical organ differentiated, subapical bulb absent (
Fig. 2
). Ant III dorsally with two globular sensilla in a cuticular fold and two guard sensilla. S.g.
v. almost
straight and subequal to S.g.d.; one ventral microsensillum (
Fig. 3
). Ant II with eleven setae. Ant. I with seven setae, including three macrosetae with blunt tips (
Fig. 2
).
Eyes absent. Head with three pairs of weakly delimited tubercles, and dorsal chaetotaxy as in
Fig. 1
and
Table 1A
. Mandibles styletiform, maxillae with a hook shape. Labrum elongate, rounded apically; formula 0/2,4 (
Fig. 4
). Labium with ten pairs of setae (
Fig. 5
). Four setae Vi on ventral side of head (
Fig. 5
), head ventral chaetotaxy in
Table 1B
.
Thoracic and abdominal dorsal chaetotaxy as in
Fig. 1
and
Table 1C
. Abd VI unilobed, lacking tubercle. Setal numbers on legs as in
Table 2
. Unguis without inner teeth (
Fig. 6
).
Ventral tube with 4+4 setae. Furcal vestige with two regular setae and one microsetae. Ventral chaetotaxy as shown in
Table 1C
and
Fig.7
. Male genital plate with 3+3 pregenital, twelve circumgenital and four pairs of eugenital setae. Each lateral anal valve with eleven regular setae and two microsetae (
Fig. 7
).
Etymology:
yunquensis
is a reference of the locality were the species was found on mountain peaks at El Yunque National Forest in
Puerto Rico
