Note on
type
locality:
The
type
locality of
H. multispinulosa
, Dilo
, could not be traced on any map or online source.
However
, it is known that the collector,
Loria
, an
Italian
anthropologist who also collected insects, studied in an area which, at that time, was
British New
Guinea
.
According
to the data in
Dimpflmeier (2019)
the area that
Loria
visited during
June and July 1890
, should lie roughly between
Maopa
(
10°8’S
,
148°1’E
) in the SE, Dorom (see above) and Gabagaba (
9°48’S
,
147°31’E
) in the NW, thus, close to the locality of the second specimen studied
.
Diagnosis.
In general habitus
H. multispinulosa
resembles
H. spada
and the other four species known to have females with an extremely prolonged ovipositor. It differs from all in the shape of the subgenital plate although a basically rhombic shape with a pair of apical spines is common to all of them. In contrast to the subgenital plate of
H. spada
that has the lateral margins slightly thickened but not upcurved, the lateral margins in
H. multispinulosa
are moderately laterally upcurved but not as strongly as in
H. pedala
sp. nov.
,
H. tuta
sp. nov.
and
H. curvata
sp. nov.
, while the apical spines are strongly up-bent as in
H. spada
. It differs from all of them by the subgenital plate that has in basal area a medial furrow but in about mid-length an angular fold that separates a strongly sclerotized anterior area from a thinner, semi-membranous apical area, which is so far unique within the genus.

(E holotype, F Rigo Dorom). Scales 10 mm.
Description.
Coloration of face uniformly pale, of general color; mandibles fully black; inner area of antennal scrobae partly brown. Femora with the following number of spines on ventral margins: (1) a 6–7, p 8; (2) a 6–7, p 4; (3) a 10–14, p 10–16 (n=2).
Male unknown.
Female. Subgenital plate about rhombic with concave anterior margin and little upcurved lateral margins, divided into two halves by a medial furrow; apico-lateral angles provided with acute upbent cones; apical margin of plate triangularly incised but that area filled by a less strong septum that connects the diverging margins unto the bases of the apical spines. Ovipositor about one and a half time as long as body; behind basal constriction straight with dorsal valves only faintly convex but not raised.
Measurements (
