Ala valvae without process on dorsal margin, slender, vaguely L-shaped, with an acute dorso-basal process (dp in Fig. 6C).

Lamella postvaginalis concave with a central swelling; ductus bursae fairly broad, forming a cervix (Figs. 14 and 17 in Birket-Smith 1965) (this character does not match the female genitalia of A. Tryphosa in the original description, but see remarks below).</p><p>Remarks. The female of A. Tryphosa (Fig. 6E), described together with the male by Kiriakoff (1958), displays different genital morphology from the other females of the group, in contrast matching well with the female genitalia of the A. flavifrontella species group above, including the species flavifrontella itself. This suggests that the female described by Kiriakoff (1958: 16–17) should be moved to the flavifrontella species group and indeed be ascribed to the species Archithosia (Acanthosia) flavifrontella, which is also present in Kiriakoff’s list (1958: 18), the female of Tryphosa thereby remaining unknown.</p><p>Archithosia parva sp. nov. is placed here only tentatively due to the missing central swelling of lamella postvaginalis.</p><p>Included species (with geographic range)</p><p>Archithosia (Acanthosia) tryphosa (Kiriakoff, 1958) (DRC, Uganda, Kenya)</p><p>Archithosia (Acanthosia) duplicata Birket-Smith, 1965 (Nigeria, Cameroon)</p><p>Archithosia (Acanthosia) similis Birket-Smith, 1965 (Cameroon, Gabon)</p><p>Archithosia (Acanthosia) parva sp. nov.

This species, very similar to all congenerics, is potentially easily discernible by means of the smaller size of the costal black dot on the forewings (this, however, needs to be validated by a more significant number of observations) The most reliable feature is genital morphology: the shape of the sterigma is unique in the whole genus, with two almost superimposed U-shaped structures (the VII sternum posterior margin—external—and the lamella antevaginalis—beneath). It might be possible to add the oval corpus bursae (too thick to be an artefact, as might result for instance from a hypothetically pressed spherical corpus), the slender ductus and the very short anterior apophyses.</p><p>Description. (Fig. 5C). Wingspan ♀ 28.5 mm. Head ochreous yellow; antennae ciliated, dorsally same colour as head, ventrally unpigmented; labial palpi porrect, not extending beyond frons, same colour as head, with distal segment beige.</p><p>Patagia, tegulae and notum ochreous yellow, thorax ventrally light beige; patagia and tegulae somewhat darker in middle. Legs same colour as thorax sternites, but forelegs darker, mid- and hindlegs lighter, internally ochreous yellow; spurs formula 0-2-4. Forewing upperside ground colour beige-dusted ochreous yellow with one black dot at middle of costa and one smaller dot in middle of space between veins CuA2 and 1A+2A. Forewing underside unmarked, light beige with margins ochreous yellow. Hindwing upperside and underside unmarked, ground colour straw yellow with slightly darker margins. Fringes concolorous with margins.</p><p>Abdomen same colour as thorax sternites,with anal tuft slightly lighter.A2 sternum apodemes long(plesiomorphic character according to Bendib &amp; Minet (1999: 243), but see also Holloway (2001: 281)). Seventh abdominal sternite slightly longer than sixth; seventh tergite twice as long as sixth. Eighth abdominal sternite coincident with lamella postvaginalis; eighth tergite about 1/5 as long as seventh tergite.</p><p>Genitalia. ♀ (Figs. 7C–F). Seventh sternite slightly sclerotised, with caudal margin (ca) swollen in a broad U-shape, covering a large well sclerotised lamella antevaginalis (la) with same shape. Eighth sternite coincident with lamella postvaginalis (lp), contiguous with lamella antevaginalis, well sclerotised, also in a broad U-shape, bearing caudally a smaller U-shaped sclerotization (us), protruding ventrally. The two lamellae compose an annular sterigma around the ostium with no clear distinction between ante- and postvaginalis.</p><p>Papillae anales (pa) smoothly squarish (in pictures appearing to taper caudally due to rolling of ventral caudal corners); anterior apophyses (aa) about 1/3 shorter than posterior apophyses (pp); posterior apophyses slender, a bit longer than papillae anales; dorsal pheromone glands (pg; Fig. 7D) unpaired, with one caudal opening at intersegmental membrane between A8 and A9, anteriorly deeply bifurcated into two finger-like lobes as long as papillae anales.</p><p>Ductus bursae (Fig. 7E) slender, membranous, as long as corpus bursae, with some sclerification (sc) in the posterior half and ductus seminalis (ds; Fig. 7D) arising dorsally from caudal end; corpus bursae (cb) oval, membranous, internally covered in tiny spines; signum (si) roundish, concave, strongly sclerotised, scobinate, with surrounding area also scobinate (Fig. 7F).</p><p>Etymology. The name of this species derives from the Latin “oblongus”, meaning elongated and referring to the oval corpus bursae along the longitudinal axis.</p></div>	https://treatment.plazi.org/id/03D187D5385D0F11FF66FA93FD5CFBE3	Public Domain	No known copyright restrictions apply.

In any case, the genitalia are clearly diagnostic: the corpus bursae is spherical and voluminous (almost as large as the whole abdomen); the ductus bursae is short, about half the diameter of the corpus: normally, i.e. in all other Archithosia except Architosia duplicata Birket-Smith, 1965, the ductus is as long as the corpus ( oblonga sp. nov., similis, tryphosa, parva sp. nov.) or longer ( flavifrontella, similis). In A. duplicata the ductus-corpus complex is very similar to that of brevis sp. nov., but the latter differs in having a shorter lamella antevaginalis, and mostly a lamella postvaginalis that is not divided into two halves as in duplicata . We also note that the signum of brevis sp. nov. is surrounded by a scobination of spines (Fig. 8 E), similar to that of flavifrontella, whereas in oblonga sp. nov. the scobination is made up of irregular smoother or more rounded granicula (Fig. 7 F).</p><p>Description.

MSNS.</p><p>Diagnosis. This species can easily be identified thanks to its small size. However, the capture of only one specimen does not allow us to consider this character as stable and certain. In any case, the forewings are more slender than those of other Archithosia species (length/width ratio 3.16, see Discussion for comments).</p><p>As usual in this genus, genital morphology represents the most concrete diagnostic feature: the broad cylindrical ductus and the pouch-like corpus are clearly diagnostic.</p><p>Description. (Fig. 5F). Wingspan ♀ 21 mm. Head with posterior region vertex beige, anterior region (between antennae) ochreous yellow; frontoclypeus darker beige than vertex; antennae ciliated, dorsally yellow, ventrally unpigmented; labial palpi porrect, not extending beyond frons, same colour as posterior region of vertex.</p><p>Patagia, tegulae and notum same colour as posterior region of vertex, patagia yellow bordered; thorax ventrally like the frontoclypeus. Legs same colour as thorax sternites, with distal end of femurs darkening; spurs formula 0- 2-4. Forewing upperside ground colour ochreous yellow, slightly dusted with beige, with one black dot at middle of costa and one smaller dot in middle of space between veins CuA2 and 1A+2A. Forewing underside unmarked, light ochreous yellow with costa and termen more intense. Hindwing upperside and underside unmarked, ground colour straw yellow with slightly darker margins. Fringes concolorous with margins.</p><p>Abdomen same colour as thorax sternites,with anal tuft slightly lighter.A2 sternum apodemes long(plesiomorphic character according to Bendib &amp; Minet (1999: 243), but see also Holloway (2001: 281)). Seventh abdominal sternite as long as sixth, broadening slightly along the pleurae; seventh tergite twice as long as sixth. Eighth abdominal sternite coincident with lamella postvaginalis; eighth tergite about 1/3 as long as sixth tergite.</p><p>Genitalia. ♀ (Fig. 9). Seventh sternite membranous with caudal margin (ca) swollen; lamella antevaginalis (la) slightly sclerotised, bar-like, laterally not well delimited, at least 1/3 as broad as seventh sternite caudal margin. Lamella postvaginalis (lp) well sclerotised, trapezoidal, almost as broad as whole eighth sternite, with caudal margin bearing U-shaped sclerotization (us) with incision in middle.</p><p>Papillae anales (pa) smoothly squarish; anterior apophyses quite stout, about 1/2 as long as sixth sternite; posterior apophyses slender, about as long as sixth sternite; dorsal pheromone glands (pg; Fig. 9B) unpaired, with one caudal opening at intersegmental membrane between A8 and A9, anteriorly deeply bifurcated into two finger-like lobes, 2/3 as long as posterior apophyses.</p><p>Ductus bursae (db) quite sclerotised, roughly cylindrical, with surface wholly scobinate (Figs. 9C, E), slightly shorter than seventh sternite, caudally and cephalically narrower and more membranous, with ductus seminalis (ds; Fig. 9B) arising from caudal end on right; corpus bursae (cb) membranous, pouch-like, with entire surface scobinate, forming fold at linkage to ductus; signum (si; Fig. 9D) ventral, nearly in middle, concave, with scobination of tiny spines.</p><p>Etymology. The name of this species derives from the Latin “parvus”, meaning small, referring to its general size.</p></div>	https://treatment.plazi.org/id/03D187D5385B0F15FF66FEA8FF5DF9A3	Public Domain	No known copyright restrictions apply.
