Adult female. ID tentative based on anal plate deeply cleaved with triangular median branches without appendages. Globulus very short, stalk nearly absent. Tergal antennal branch longer than sternal. Head with anterior two rows of setae inflated and pubescent. Posterior two rows mostly inflated and less pubescent, lateral pairs of fourth row longer and less pubescent/inflated. Temporal organ with small pore, no pistil. Collum process medially creased, apically split. Setae of collum and coxae/trochanters platelike, with a small articulated appendage. Empodium with at least 2 well developed claws, pad divided into two "toes." 9th tarsus with a long obliquely ciliate proximal seta and a relatively long striate seta. Tergite 1 with anterior and posterior row of 2 setae; 2 with anterior of 4 and posterior of 6; 3-4 with anterior of 3 and posterior of 3; 5 with anterior of 3 and posterior of 2; 6 with anterior of 2 and posterior of 1. T1-2 thin and with fine erect ciliation; T3-4 thicker and with thick oblique ciliation; T5 with extremely reduced oblique ciliation. A2-3 longer than a1, a2 angularly bent. Pygidium tergum with a medially indented posterior lappet. Pygidium sternum with a low rounded posterior bump. St cylindrical, short. B1 very long, b2-3 about as long as a2-3, b3 apically inflated. Anal plate cleaved nearly to base, triangular medial branches without appendages, very thing lateral branches.
Female sperm receptacle and genital atrium observed, imaged. Duct leading to sperm receptacle much longer than the one described for P. silvaticus, long, tube like, and corrugated. Spermatophores visible inside ellipsoid receptacle.
Small indentations and invavigations at the bases of all legs observed; very likely these are the remants of tracheae due to structure.

Keys to this genus, but I have doubts. Hind femur with dorsal macroseta, mesonotum with 3+3 macrosetae, and abdominal tergite 8 with 4+4 lateral macrosetae makes this Clivocampa. But the bacilliform sensillum is inserted between phanere d and e instead of c and d and there appear to be chaetotaxic differences in some of the abdominal segments.

Head of a remarkable structure, completely unlike any other pauropoda. Closest analogue I can think of is some members of Brachypauropodidae. Antennal segments extremely short and flattened, 4 in number. Tergal antennal branch very small, bearing a well developed flagellum. Sternal antennal branch very large, bearing a globulus and three flagella, one of which is less well developed than the rest. Globulus with an outer ring of around 12 bracts and an inner ring of 3 bracts. All flagelli, with the possible exception of the smallest on the sternal branch, with a biramous calyx in the form of a larger appendage curving around the smaller. Temporal organ of the form seen in Millotauropus. Collum indistinct, invisible in a dorsal view and without any setae. Setae of trunk extremely small, sparse, and spinelike. T1-4 filamentous, bristly. T5 thicker, ciliate. Pygidium dorsum in adults with at least 4 setae. Pygidium sternum in adults with 6 setae. Both the tergite and sternite are very thick, and completely envelop the anal plate(if present, may be replaced by cuticular appendages like in Polypauropodidae.) Last pair of legs, and maybe first, with only 4 segments. All other legs with 5 segments. All legs nearly devoid of the usual setae, what's present being highly reduced. Empodium of two claws and a pad.

Same situation as https://www.inaturalist.org/observations/153459428, but a distinctly different species. Differs from the other species in the shape and number of bracts of the globulus, the shape of the flagellar calyx, the length of the pygidial a1 setae, the shape of the anal plate, the shape of the setae of the head, and the lack of a temporal organ vesicle, among other differences.

Conspecific with https://www.inaturalist.org/observations/152898844. T3 differentiated from t4 and presumably 5 in adults by the shorter length and anteriorly developed ciliation. Of extreme interest is the external vesicle of the temporal organ; I've yet to read about a member of the genus with one and it seems to be rare overall in the family.

Probably a new species, due to the anterior row of setae on tergal plate 1 being significantly larger than the posterior row (equal or smaller in D. luteus and D. magnus. Literature lacking for D. macswaini.)
