Remarks 
Agauopsis ornatella is a member of the ornata 
group. The most prominent characters of this 
group are: porose areolae of dorsal plates with 
distinct alveoli and numerous canaliculi, ventral 
plates with garland-like arranged porose polygons. 
P-2 with tapering bristle-like spine. P-4 with two 
basal setae, an apical setula and two minute spurs. 
Legs with lamellae. Telofemur I with one 
ventromedial and two to three ventrolateral spines, 
tibia I with two ventromedial and one ventral 
spine. All tarsi with three dorsal setae. Tarsus II 
with lateral pas and ventral seta, and tarsi III and 
IV each with medial but no lateral pas. Members of 
the ornata group are A. bacescui Konnerth-Ionescu, 
A. bemiudensis Bartsch and Iliffe, A. mflata Newell, 
A. ornata (Lohmann), and A. pseudoomata Bartsch. 
A. punctata and A. aequilivestita are very closely 
related with the ornata group but their ventral 
plates lack the garland-like porose areolae. 
A. ornatella is characterized by its frontal process 
with the two narrow ridges, the costae on PD being 
a single alveolus wide, the rather narrow porose 
areolae on the AE and the area with the lateral 
garland being raised. The Philippine A. 
pseudoomata has a triangular frontal process with a 
pair of rounded porose areolae, the costae on the 
PD are three porose polygons wide, the porose 
areolae of the AE are distinctly wider (Bartsch 
1985a). The eastern African A. bacescui has, 
compared with A. ornatella, a longer frontal spine, 
the costae on PD are two porose polygons wide, 
and telofemur I bears four spines (Konnerth- 
Ionescu 1977). 
Genus Halacaropsis gen. nov. 
Type species 
Agaue hirsuta Trouessart, 1889. 
Diagnosis 
Dorsum with AD, OC and PD and the five pairs 
of setae ds-1 to ds-5. Adanal setae on anal plate, 
often in ventral position. AE with three pairs of 
ventral setae and pair of epimeral pores. PE with 
one dorsal and three ventral setae. Female GA with 
four to eight pairs of pgs and two to six pairs of 
subgenital setae. Male GA with about 50 
perigenital setae close around GO; one or two pairs 
of setae may be outlying. Gnathosomal base 
quadrangular, rostrum parallel-sided. One pair of 
maxillary setae on gnathosomal base, one pair in 
distal rostrum. Palps four-segmented, attached 
laterally to base of gnathosoma. P-2 with dorsal 
seta, P-3 with dorsomedial seta, P-4 with three 
setae in basal whorl, one setula and two spurs 
apically. Leg I long and stout, telofemur, genu and 
tibia I with large spines; tarsus I with ventromedial 
spine. Solenidion on tarsus I in dorsolateral 
position, on tarsus II in dorsomedial position. All 
tarsi with ventral setae. Median claw on all tarsi 
stouter than paired claws. One larval and two 
nymphal stages present. 
Remarks 
The genus Halacaropsis includes the species 
formerly assigned to the Agauopsis hirsuta group as 
defined in Bartsch (1986). Halacaropsis differs from 
representatives of the genus Agauopsis in the larger 
number of ventral setae on the tarsi I and II and 
the presence of ventral setae on tarsi III and IV. 
Moreover, tarsi of representatives of Halacaropsis 
have a remarkably enlarged median claw, much 
larger than that of Agauopsis ; and the tarsi of the 
hind legs of Halacaropsis are rather slender, they 
may be somewhat curved. In juveniles of 
Halacaropsis are PD and anal plate widely 
separated, in juveniles of Agauopsis, PD and anal 
plate often are adjacent. 
Halacaropsis resembles Agauopsis in the 
chaetotaxy of tibia I, and Halacams in the number 
of ventral setae on the tarsi and the cerotegumental 
swellings on the plates.
