Notes on the status of Protosticta khaosoidaoensis Asahina, 1984 

( Figure 10View FIGURE 10 A–E)

Protosticta khaosoidaoensis: Asahina (1984)  , pp. 588–590, Figs. 8View FIGURE 8 –15. Type locality: Khao Soi Dao mountains, Thailand.— Hämäläinen & Pinratana (1999), p. 60 (Chiang Mai, Chantaburi).—van Tol (2008), pp. 220–221, Figs. 5–10View FIGURE 5View FIGURE 6View FIGURE 7View FIGURE 8View FIGURE 9View FIGURE 10.

Protosticta khaosoidaoensis khaosoidaoensis: Kitagawa & Katatani (2002)  , pp. 33–34, Fig. 1View FIGURE 1 (Pong Nam Ron, Khao Soi Dao).

The material identified in van Tol (2008) as this species, but no longer considered to belong to it: 2 males, Huong Son district, Ha Tinh Province, 2.VII. 1990; 1 male, Ky Son district, Nghe An Province, 8.VII. 1990; 2 males, Thanh Chuong district, Nghe An Province, 11-12.VII. 1990; 1 male, Doi Suthep, Chiang Mai, Thailand (JvT 19422).

Specimens examined. 1 male, Krating waterfall, Chantaburi Province, Thailand, 10.VII. 2011; 2 females, Krating waterfall, Chantaburi Province, Thailand, 03.IV. 2015, Noppadon Makbun leg.

Notes. Van Tol (2008) recorded P. khaosoidaoensis  from Huong Son district, Ha Tinh Province of central Vietnam based on a comparison with a male of P. khaosoidaoensis  from Doi Suthep in Chiang Mai Province, Thailand. Although he recognized that the Vietnamese specimen resembled P. c ur i o s a, he identified it as P. khaosoidaoensis  based on the similarity of the color pattern of the prothorax to the original description ( Asahina 1984). To ascertain the status of P. khaosoidaoensis  in Vietnam, we examined the types and other specimens of this species from its type locality (Chantaburi, Thailand) and compared these with the Vietnamese and Thai P. khaosoidaoensis  illustrated by van Tol (2008: p. 221, Figs. 5–10View FIGURE 5View FIGURE 6View FIGURE 7View FIGURE 8View FIGURE 9View FIGURE 10).

Surprisingly, the male " P. khaosoidaoensis  " from Doi Suthep illustrated by van Tol (2008: p. 221, Figs. 5–7View FIGURE 5View FIGURE 6View FIGURE 7) is different from P. khaosoidaoensis  in several characters: (1) in P. khaosoidaoensis  , the paraprocts have elongated tips, extending as far as the cerci ( Fig. 10View FIGURE 10 B and Fig. 13, p. 589, Asahina 1984), but are very short in van Tol's specimen (2008: p. 221, Fig. 6View FIGURE 6); (2) in P. khaosoidaoensis  the paraprocts have at their dorsal apex a large cup-like structure with a small spine ( Fig. 10View FIGURE 10 B) that is absent in van Tol's male (van Tol 2008: p. 221, Fig. 7View FIGURE 7). Therefore, it appears that the male P. khaosoidaoensis  from Doi Suthep illustrated by van Tol (2008) does not represent true P. khaosoidaoensis  .

Van Tol (2008) also questioned whether P. c u r i o s a and P. khaosoidaoensis  are truly distinct species, as structural differences seemed to be small. In fact there are some clear differences. Whereas P. khaosoidaoensis  has a large cup-like structure with a large spine on its distal margin at the dorsal apex of the paraprocts ( Fig. 5View FIGURE 5 B), P. curiosa  has only a very small cup-like structure lacking a spine ( Fig. 9View FIGURE 9 N). The female of P. c ur i os a differs from the female of P. khaosoidaoensis  by a large oval yellow spot on the dorsum of S 9 ( Fig. 9View FIGURE 9 Q), whereas this segment is generally, but not always, entirely black in P. khaosoidaoensis  ( Fig. 10View FIGURE 10 E).

The Vietnamese material identified by van Tol (2008) as " P. khaosoidaoensis  " is clearly much closer to P. curiosa  than to P. khaosoidaoensis  . Therefore we reject his specimen as P. khaosoidaoensis  and cannot support the occurrence of that species in Vietnam. In fact his material matches our description of P. pseudocuriosa  spec. nov.

from the same locality, especially by having the same two small oval yellow spots at the posterior end of the mesepisternum and mesepimeron (van Tol 2008: p. 221, Fig. 8View FIGURE 8). This character is absent in P. khaosoidaoensis  ( Figs. 10View FIGURE 10 A, 10 D) and P. c u r i o s a ( Fig. 9View FIGURE 9 P).

Distribution. Thailand (Chantaburi and Chiang Mai Provinces), Lao PDR (Louang Phabang, Oudomxay Province).
