Description.
Length
0.96 to 1 mm
. Body without pigment, 4 + 4 eyes with pigment, two anterior corneola of the same size, the two posterior smaller, rate 0.76 (
Fig. 7
).
Antenna without pigment, its proportion with head is 1.40. Rate of Ant. I:II:III:IV is 15:22:18:42. Ant. IV without apical bulb. Apical organ of third antennal segment peg or rod-like. Labial formula: M1 M2REL1 L2, all ciliated, ratio R with seta M1 is 2.1. R is one microseta (
Fig. 6
).
Dorsal macroseta formula: R001/10/0101+2. Chaetotaxy of Abd. II: -aBq1q2 (
Fig. 10
). Without accessory seta “s” on Abd. IV (
Fig. 8
,
Tab. 1
).

Pseudosinella luenganensis
sp. nov.
: 6, labium; 7, eyes; 8, chaetotaxy of Abd. IV; 9, unguis III; 10, chaetotaxy of Abd. II.
Tibiotarsus with capitate tenent hair, but specimens from sample C: 2294 have tenent hair acuminate, its rate with the length of internal unguis 0.78, differentiated inner seta on hind tibiotarsus clear acuminate. Unguis with an intermedian tooth, located about 64% of the length of the internal side of the unguis. There is a basal pair of teeth, one of them better developed, almost twice the size of the other, and located at 35% of internal side of unguis and the other is more distal and smaller, located about 53.5%. Empodium lanceolate and approximately 0,78 the length of unguis. Legs without scales (
Fig. 9
). All other characters after Christiansen
et al
. (1999) (
Tab. 3
). Retinaculum with 4+4 teeth and no seta in the base. With 2 inner and 2 outer seta in the manubrial plaque. Mucro bidentate, with one seta on its base.
Remarks.
The new species presents the same dorsal chaetotaxy than:
P. oromii
Gama
,
P. decui
Gruia
,
P. bohemica
Rusek
and
P. pallida
Gruia. They
differ from all of them mainly by the number of eyes, chaetotaxy of Abd. II and the labial seta formula (
Table 1
).
