Figure 58, 99, 110

Ctenoplus brunneus Fleutiaux 1940b: 197 ; sex and number of specimens not stated; type locality: “ Laos: Haut­Mékong, Ban Mone, mai ( Vitalis de Salvaza )”.

Diagnosis

Medium sized, uniformly brown Ctenoplus indistinguishable externally from C. coomani Fleutiaux. In the female genitalia of C. brunneus , the tubular extension is less elaborately coiled and relatively shorter ( Fig. 99 ). In C. coomani , the tubular extension is relatively long and has a characteristic proximal and distal set of coils ( Fig. 98 ). The male of C. brunneus is unknown.

Description

As in C. coomani , except as noted.

Colour slightly darker than C. coomani , with setae slightly more yellowish. Length: 8.0 mm; width: 2.0 mm (n=1).

Female genitalia, Fig. 99 ; bursa copulatrix with band of individual thorn­like spines in concavity of bursal plates and continuing around base of tubular extension; tubular extension: long, proximal 1/2 uncoiled, distal 1/2 strongly coiled (8–9 coils); with 2 bands of spines increasing in width distally, extending almost to spermathecal gland, spines with expanded bases; spermatheca absent.

Type material

C. brunneus was described based on an unspecified number of specimens collected in Laos. A single female specimen was received from MNHN. It bears the following labels: “Ban Mone, Ht Mekong, 16­5­18" [handwritten]/ “ LAOS, LUANG PRABANG ENVIRONS, VITALIS DE SALVAZA”/ “ TYPE “[red ink]/ “ Ctenoplus brunneus Fleut. type” [handwritten] “COLLECTION FLEUTIAUX”. This specimen is here designated the lectotype .

Material examined and range The lectotype is the only known specimen ( Fig. 110 ).
